infections in healthcare workers: guidelines for prevention and
management in industrialised countries. Occup Environ Med
SUMMARY - The Viral Hepatitis Prevention Board (VHPB) convened a meeting of international experts from the public and private sectors in order to review and evaluate the epidemiology of blood-borne infections in healthcare workers, to evaluate the transmission of hepatitis B and C viruses as an occupational risk, to discuss primary and secondary prevention measures and to review recommendations for infected healthcare workers and (para)medical students. This VHPB meeting outlined a number of recommendations for the prevention and control of viral hepatitis in the following domains: application of standard precautions, panels for counselling infected healthcare workers and patients, hepatitis B vaccination, restrictions on the practice of exposure-prone procedures by infected healthcare workers, ethical and legal issues, assessment of risk and costs, priority setting by individual countries and the role of the VHPB. Participants also identified a number of terms that need harmonization or standardisation in order to facilitate communication between experts.
Strauss KW, Onia R, Van Zundert AA. Peripheral intravenous catheter
use in Europe: towards the use of safety devices. Acta Anaesthesiol
BACKGROUND: Peripheral intravenous catheters are among the most widely used medical devices in the world. European patients are increasingly aware of the risk of health care associated infections and the role catheters play in their facilitation. AIMS: We intend to show that European health care providers are increasingly aware of the occupational risks of bloodborne infections such as HIV and hepatitis which can be transmitted by the needles from catheters and that the political will is building to take action to ensure safer devices are provided. METHODS: We review the wide variety of peripheral intravenous catheters which are specially engineered to reduce these risks. RESULTS: Available safety devices include spring-loaded retractable needles, guards that shield the dangerous tips and closed, needle-free access valves for intravenous sets. CONCLUSIONS: It is no longer necessary for patients and professionals to take risks to health and life when solutions which minimize these risks are at hand.
Clarke SP, Schubert M, Korner T. Sharp-device injuries to hospital
staff nurses in 4 countries. Infection Control and Hospial Epidemiology
ABSTRACT- Objective: To compare sharp-device injury rates among hospital staff nurses in 4 Western countries. Design: Cross-sectional survey. Setting: Acute-care hospital nurses in the United States (Pennsylvania), Canada (Alberta, British Columbia, and Ontario), the United Kingdom (England and Scotland), and Germany. Participants: A total of 34,318 acute-care hospital staff nurses in 1998-1999. RESULTS: Survey-based rates of retrospectively-reported needlestick injuries in the previous year for medical-surgical unit nurses ranged from 146 injuries per 1,000 full-time equivalent positions (FTEs) in the US sample to 488 injuries per 1,000 FTEs in Germany. In the United States and Canada, very high rates of sharp-device injury among nurses working in the operating room and/or perioperative care were observed (255 and 569 injuries per 1,000 FTEs per year, respectively). Reported use of safety-engineered sharp devices was considerably lower in Germany and Canada than it was in the United States. Some variation in injury rates was seen across nursing specialties among North American nurses, mostly in line with the frequency of risky procedures in the nurses' work. Conclusions: Studies conducted in the United States over the past 15 years suggest that the rates of sharp-device injuries to front-line nurses have fallen over the past decade, probably at least in part because of increased awareness and adoption of safer technologies, suggesting that regulatory strategies have improved nurse safety. The much higher injury rate in Germany may be due to slow adoption of safety devices. Wider diffusion of safer technologies, as well as introduction and stronger enforcement of occupational safety and health regulations, are likely to decrease sharp-device injury rates in various countries even further.

et al. Risk factors for hepatitis C virus transmission to health care
workers after occupational exposure: a European case-control study.
Clinical Infectious Diseases 2005;41:1423-30.
ABSTRACT- Background: Additional studies are required to identify risk factors for hepatitis C virus (HCV) transmission to health care workers after occupational exposure to HCV. Methods: We conducted a matched case-control study in 5 European countries [France, Italy, U.K., Switzerland, Spain] from 1 January 1991 through 31 December 2002. Case patients were health care workers who experienced seroconversion after percutaneous or mucocutaneous exposure to HCV. Control subjects were HCV-exposed health care workers who did not experience seroconversion and were matched with case patients for center and period of exposure. Results: Sixty case patients and 204 control subjects were included in the study. All case patients were exposed to HCV-infected fluids through percutaneous injuries. The 37 case patients for whom information was available were exposed to viremic source patients. As risk factors for HCV infection, multivariate analysis identified needle placement in a source patient's vein or artery (odds ratio [OR], 100.1; 95% confidence interval [CI], 7.3-1365.7), deep injury (OR, 155.2; 95% CI, 7.1-3417.2), and sex of the health care worker (OR for male vs. female, 3.1; 95% CI, 1.0-10.0). Source patient HCV load was not introduced in the multivariate model. In unmatched univariate analysis, the risk of HCV transmission increased 11-fold for health care workers exposed to source patients with a viral load >6 log(10) copies/mL (95% CI, 1.1-114.1), compared with exposures to source patients with a viral load < or =4 log10 copies/mL. Conclusion: In this study, HCV occupational transmission was found to occur after percutaneous exposures. The risk of HCV transmission after percutaneous exposure increased with deep injuries and procedures involving hollow-bore needle placement in the source patient's vein or artery. These results highlight the need for widespread adoption of needlestick-prevention devices in health care settings, together with other preventive measures.

Occupational Post-Exposure Prophylaxis Study Group. Towards a standard
HIV post exposure prophylaxis for healthcare workers in Europe. Euro
ABSTRACT- Antiretroviral prophylaxis (PEP) after occupational exposure to HIV in healthcare workers (HCWs) is used across Europe, but not in a consistent manner. A panel of experts, funded by the European Commission, formulated a set of recommendations. When it has been decided that the characteristics of the exposure indicate the initiation of PEP, PEP should be started as soon as possible; initiation is discouraged after 72 hours. PEP should be initiated routinely with any triple combination of antiretrovirals approved for the treatment of HIV-infected patients; a two class regimen is to be preferred. The source patient's treatment history should be sought. Counselling, psychological support, HIV testing and clinical evaluation should be performed at baseline, at 6-8 weeks, and at least 6 months post exposure. Additional clinical and laboratory monitoring at one and two weeks should be considered, as adherence with and tolerance of the regimen can highlight adverse reactions and potential toxicity. Routine HIV resistance tests in the source patient, and direct virus assays in the exposed HCW are not recommended.

SUMMARY: In Europe (Europe of the Twelve plus Austria, Finland, Norway, Sweden and Switzerland) 6.5 million workers (or 6.8 including students) are potentially exposed to the hazards of blood contact. Before studying the incidence and the causes of blood exposures the characteristics and risk factors of accidents that have led to infection by [HIV, hepatitis B and hepatitis C] will be reviewed, based on European data.

Moens G, Mylle G, Johannik K, Van Hoof R, Helsen G. Analysing and
interpreting routinely collected data on sharps injuries in assessing
preventative actions. Occup Med 2004;54(4):245-9.
BACKGROUND: Sharps injuries (SI) occur frequently in hospitals and are a risk for exposure to bloodborne pathogens. During the 1990s, the safety service of a university general hospital introduced, in collaboration with the occupational health service, specific measures to reduce the number of SI. AIM: The aim of this study was to assess the occurrence and evolution of SI during this period and to evaluate the effectiveness of the preventative measures taken, making use of routinely collected data. METHOD: In a retrospective study, we analysed the number of SI recorded from 1990 to 1997. The study population was all employees at risk of SI. Because the introduction of intensive preventative measures dates from 1996, an effect on the incidence of SI can be expected from 1996. To assess this effect, mean incidence rates for 1990-1995 and for 1996-1997 were compared. RESULTS: In the study period, a total of 4230 SI were recorded. The global SI incidence rate decreased from 33.4 SI per 100 occupied beds per year in 1990-1995 to 30.1 in 1996-1997 (P < 0.01). In the same period, among nurses a decrease in incidence rate from 17.2 to 12.7 SI per 100 person-years was noted (P < 0.0001) and for the hotel service from 4.8 to 3.7 (not significant). CONCLUSION: Although this study has various restraints, these results suggest that intensive preventative actions, in combination with technological advances, may have contributed to a drop of 67 SI cases per year.

Blood borne viral infections among Danish health care workers--frequent
blood exposure but low prevalence of infection. European Journal of
ABSTRACT- Denmark is a country with low prevalence and incidence of blood borne viral infections. Among health care workers (HCWs) vaccination for hepatitis B is only offered to high-risk groups. The aims of this cross sectional survey were to determine the prevalence of hepatitis B, -C, and human immunodeficiency virus (HIV) among the staff at a Danish University hospital and to correlate this with risk factors for transmission. Additionally, we wanted to examine the current frequency of blood exposure, reporting habits and hepatitis B vaccination status in the staff. Of 1439 eligible hospital staffs included, 960 (67%) were HCWs. The overall prevalence of human immunodeficiency virus (HIV), hepatitis C Virus (HCV), and hepatitis B virus (HBV) was 0% (0/1439), 0.14% (2/1439), and 1.6% (23/1439), respectively. Twenty-three percent of HCWs were vaccinated against HBV. Age, blood transfusion and stay in endemic areas were associated independently to HBV infection as opposed to job-category, duration of employment, HBV vaccination status and blood exposure. Based on a 4-week recall period, the incidence of percutaneous blood exposure was 1.5/person-year. In conclusion the HIV and hepatitis prevalence was low despite frequent blood exposure and the principal risk factors were unrelated to work. Danish HCWs do not seem to be at increased risk of hepatitis B even though universal HBV vaccination has not been implemented.
Nelsing S, Nielsen TL, Nielsen JO. Percutaneous blood exposure among
Danish doctors: exposure mechanisms and strategies for prevention. Eur
J Epidemiol 1997;13:387-93.
ABSTRACT- The objective of this study was to describe the mechanisms of percutaneous blood exposure (PCE) among doctors and discuss rational strategies for prevention. Data were obtained as part of a nation-wide questionnaire survey of occupational blood exposure among hospital employed doctors in Denmark. The doctors were asked to describe their most recent PCE, if any, within the previous 3 months. Detailed information on the instruments, procedures, circumstances and mechanisms that caused the PCE was obtained. Of 9375 doctors, 6256 (67%) responded, and 6005 questionnaires were eligible for analysis. Of 971 described PCE the majority were caused by suture needles (n = 483), IV-catheter-stylets (n = 94), injection needles (n = 75), phlebotomy needles (n = 53), scalpels (n = 45), arterial blood sample needles (n = 41) and bone fragments (n = 23). Inattentiveness was the most common cause, contributing to 30.5% of all PCE. Use of fingers rather than instruments was a major cause of injury in surgical specialties and was a contributing cause of 36.9% PCE on suture needles. Common contributing causes when fingers were used (n = 199) were poor space in (30.2%) or view of (18.6%) the operation field. It was often argued that instruments were not practical to use or might harm the tissue. Of 689 PCE in surgical specialties, 17.4% were inflicted by colleagues. Up to 53.3% of PCE on hollow-bore needles could be attributed to unsafe routines like recapping only, but other mechanisms like sudden patient movements and acute situation were common, especially in the case of PCE on iv-catheter-stylets. It is concluded that the exposure mechanisms of PCE reflect both unsafe routines, difficult working conditions and unsafe devices. Education in safer working routines are needed in all specialties. Introduction of safer devices should have a high priority in surgical specialties, and should be considered in non-surgical specialties too.
Pedersen EB. [Potentially hazardous exposure to blood among hospital
personnel: A retrospective study of systematically registered exposure
during the period 1990-1994.] [Danish]. Ugeskr Laeger
ABSTRACT- The purpose of this study was to investigate the self-reported incidence of needlesticks and other exposures to patients' blood or body fluids among employees at Glostrup County Hospital, Copenhagen. Furthermore the nature of and circumstances under which these exposures occurred were explored. Four hundred and thirty-two reports of exposure were received from 389 health care workers during a period of four years (1990-1994). Ninety-three percent of the exposures were percutaneous, 7% mucocutaneous. The incidence rates of exposure per full-time employee per year were as follows: Midwives: 0.11; doctors: 0.093; laboratory - technicians: 0.084; registered nurses: 0.068; auxiliary nurses: 0.025; porters: 0.024 and housekeeping staff: 0.016. Accidents related to disposal containers, where the health care worker is injured while disposing a needle or handling the disposal container, account for 10% of all percutaneous exposures. Improper placing of sharp instruments account for 7% and recapping is responsible for 6% of all percutaneous exposures. Mucocutaneous exposure was caused by unexpected splash during the procedure, in 86% of the cases the conjunctivae were contaminated. No occupationally acquired infections were observed. It is concluded that occupational exposure to blood and body fluids among health care workers is considerable. To reduce the frequency of blood exposure education of the health care workers and safer equipment are needed. A good strategy for preventing exposures must be based on careful registration of the accidents, which is obtained by encouraging reporting of the exposures among the health care workers. Data base registration would be desirable.

ABSTRACT- We investigated mechanisms of mucocutaneous exposure (MCE) and percutaneous exposure (PCE) to blood, and compliance with protective barriers among all former and presently employed medical staff at a Danish Department of Infectious Diseases. All subjects were asked to complete an anonymous questionnaire. 135 out of 168 (80%) subjects responded. 37 incidents of PCE and 15 MCE were described. More than 50% of PCE had occurred without obvious explanation during medical procedures, or were caused by unexpected patient movement, while only 1 PCE was caused by recapping. 35% of PCE occurred during drawing of venous blood samples. Compliance with usage of gloves was high (70-100%), depending on the procedure, and 72% of the subjects claimed to have sufficient knowledge of the risk of blood exposure and how to prevent it. Yet 11 (73%) out of 15 MCE might have been prevented by appropriate use of protective barriers. To further reduce the frequency of blood exposure, the development of safer instruments and unceasing education in safer technique and use of protective barriers are of major importance.

health-care workers (HCW) in a department of infectious diseases (DID).
International AIDS Conference 1992 (Jul 19-24);8:179 (abstract no. PuC
ABSTRACT- Objective: To study the epidemiology of blood exposure among staff in a DID with a high prevalence of HIV-positive patients, from 1987-1991. Methods: All former and present employed staff members, attending physicians and chief physicians, nurses and nursing assistants were asked to fulfill an anonymous questionnaire. Subjects were asked to detaily describe all percutaneous (PCE) and mucocutaneous (MCE) exposures to blood during their employment at the department. Results: 80% (135 out of 168) responded. 45 persons experienced 37 PCE and 15 MCE. In 83% of the exposures the index patient was known to be HIV-positive. In 73% of PCE and 33% of MCE the subject had a HIV test performed. 65% of PCE and only 13% of MCE were reported. 76% of the subjects claimed to wear appropriate protection during the exposure. Rate of PCE per person year (py) was highest among staff members 0.51 PCE/py compared to 0.09-0.11/py among other groups. Staff members perform the major part of sharp procedures. Rates of MCE/py was highest among doctors in general 0.17-0.21/py and lowest among nurses 0.03 MCE/py. Almost 50% of PCE happened during the first 6 months of employment. No relation between anciennity and exposure rates in general was found for neither staff members, nor nurses. Exposure mechanisms were for PCE: Unexpected patient movement 8, during disposal 7, picking up instrument 4, left instrument 2, recapping 1, stuck by colleague 1, during procedure 12. For MCE: Unexpected patient movement 3, unexpected colleagues movement 1, during procedure 11. Conclusions: Blood exposure is still a considerable problem, even among staff experienced in caring for patients with infectious diseases. Recapping was no major cause of PCE in this study. Most PCE happens during the first 6 months of employment, while anciennity does not seem to influence on the risk of blood exposure. Staff members are at highest risk of blood exposure. The importance of reporting and being HIV-tested following blood exposures needs to be stressed.

types of safety-engineered devices: results of a French multicenter
study. Infect Control Hosp Epidemiol. 2010 Apr;31(4):402-7.
OBJECTIVES: To evaluate the incidence of needlestick injuries (NSIs) among different models of safety-engineered devices (SEDs) (automatic, semiautomatic, and manually activated safety) in healthcare settings. DESIGN: This multicenter survey, conducted from January 2005 through December 2006, examined all prospectively documented SED-related NSIs reported by healthcare workers to their occupational medicine departments. Participating hospitals were asked retrospectively to report the types, brands, and number of SEDs purchased, in order to estimate SED-specific rates of NSI. Setting. Sixty-one hospitals in France. RESULTS: More than 22 million SEDs were purchased during the study period, and a total of 453 SED-related NSIs were documented. The mean overall frequency of NSIs was 2.05 injuries per 100,000 SEDs purchased. Device-specific NSI rates were compared using Poisson approximation. The 95% confidence interval was used to define statistical significance. Passive (fully automatic) devices were associated with the lowest NSI incidence rate. Among active devices, those with a semiautomatic safety feature were significantly more effective than those with a manually activated toppling shield, which in turn were significantly more effective than those with a manually activated sliding shield (P < .001, chi(2) test). The same gradient of SED efficacy was observed when the type of healthcare procedure was taken into account. CONCLUSIONS: Passive SEDs are most effective for NSI prevention. Further studies are needed to determine whether their higher cost may be offset by savings related to fewer NSIs and to a reduced need for user training.

Risk of needlestick injuries among nurses using novofine® autocover® safety needles and nurses' satisfaction with the needles: The NOVAC Study. Insulin 2008;3(4):232-7. ABSTRACT - Background: Needlestick injuries among health care professionals are a costly problem, both economically and in terms of anxiety and stress. NovoFine® Autocover® (NFA) 30G safety needles (Novo Nordisk A/S, Bagsvaerd, Denmark) were designed to minimize the risk of such injuries when used with insulin pens, which are increasingly preferred over syringes for injecting insulin. Objective: This prospective study compared the risk of needlestick injury with NFA needles and regular needles on insulin pens among nurses who administered insulin to patients. Methods: Nurses with ≥3 months' experience in diabetes care were eligible for participation. Nurses were trained in the use of NFA needles and then instructed to use them in their daily practice for 4 weeks, recording details of the injections administered and any injuries that occurred in a logbook. Results: A total of 143 nurses at 52 hospitals located throughout France received training. Demographic data were available for 139 nurses (mean age 38.4 years, 96.4% female, with a mean of 8 years' diabetes experience): 123 of the nurses used NFA needles (7854 injections administered), 122 of whom also used regular needles (4491 injections). No needlestick injuries occurred with NFA needles, whereas 1 needlestick injury occurred with a regular needle. Nurses were very satisfied with the NFA needles, giving them a score of 8.1 on a scale of 0 to 10, rating personal safety as a particularly important benefit (score 9.5). Nurses preferred NFA needles to both regular needles on insulin pens and needles on syringes, citing personal safety and the saving of time as the main reasons. Conclusions: These results suggest that NFA needles could reduce the risk of needlestick injuries and that nurses would welcome their other advantages, such as ease of use and saving of time.

Post-exposure prophylaxis with a maraviroc-containing regimen after
occupational exposure to a multi-resistant HIV-infected source person.
Journal of Medical Virology 2008;80:9-10.
ABSTRACT- We report the case of a health care worker who received a post-exposure prophylaxis including an investigational drug, maraviroc, after a needlestick percutaneous injury to an HIV-infected patient with late-stage disease and harboring a multi-drug resistant virus. Post-exposure prophylaxis including maraviroc was pursued for a total of 28 days, with a weekly clinical and biological evaluation. Post-exposure prophylaxis was well tolerated, with no increase in liver function tests. The health care worker remained HIV-negative after a 6- month follow-up.

needlestick injuries in 32 French hospitals. Infect Control Hosp
ABSTRACT - Objectives: To evaluate safety-engineered devices (SEDs) with respect to their effectiveness in preventing needlestick injuries (NSIs) in healthcare settings and their importance among other preventive measures. Design: Multicenter prospective survey with a 1-year follow-up period during which all incident NSIs and their circumstances were reported. Data were prospectively collected during a 12-month period from April 1999 through March 2000. The procedures for which the risk of NSI was high were also reported 1 week per quarter to estimate procedure-specific NSI rates. Device types were documented. Because SEDs were not in use when a similar survey was conducted in 1990, their impact was also evaluated by comparing findings from the recent and previous surveys. Setting: A total of 102 medical units from 32 hospitals in France. Participants: A total of 1,506 nurses in medical or intensive care units. Results: A total of 110 NSIs occurring during at-risk procedures performed by nurses were documented. According to data from the 2000 survey, use of SEDs during phlebotomy procedures was associated with a 74% lower risk (P<.01). The mean NSI rate for all relevant nursing procedures was estimated to be 4.72 cases per 100,000 procedures, for a 75% decrease since 1990 (P<.01); however, the decrease in NSI rates varied considerably according to procedure type. Between 1990 and 2000, decreases in the NSI rates for each procedure were strongly correlated with increases in the frequency of SED use (r=0.88; P<.02). Conclusion: In this French hospital network, the use of SEDs was associated with a significantly lower NSI rate and was probably the most important preventive factor.

healthcare worker to a patient. Infection Control and Hospital
ABSTRACT- We investigated the source of infection in a patient who developed acute hepatitis C virus infection after cardiothoracic surgery. A healthcare worker was found to be infected with hepatitis C virus, and molecular analysis indicated the strain was similar to that found in the patient. The exact mode of transmission was not identified; however, atopic eczema on the healthcare worker's hands may have contributed to the transmission.

blood and body fluid exposures among French healthcare workers in 2004.
Infection Control and Hospital Epidemiology 2007;28:1196-201.
ABSTRACT- Objective: To estimate the incidence rate of reported occupational blood and body fluid exposures among French healthcare workers (HCWs). Design: Prospective national follow-up of HCWs from January 1 to December 31, 2004. Setting: University hospitals, hospitals, clinics, local medical centers, and specialized psychiatric centers were included in the study on a voluntary basis. Participants: At participating medical centers, every reported blood and body fluid exposure was documented by the occupational practitioner in charge of the exposed HCW by use of an anonymous, standardized questionnaire. Results: A total of 375 medical centers (15% of French medical centers, accounting for 29% of hospital beds) reported 13,041 blood and body fluid exposures; of these, 9,396 (72.0%) were needlestick injuries. Blood and body fluid exposures were avoidable in 39.1% of cases (5,091 of 13,020), and 52.2% of percutaneous injuries (4,986 of 9,552) were avoidable (5.9% due to needle recapping). Of 10,656 percutaneous injuries, 22.6% occurred during an injection, 17.9% during blood sampling, and 16.6% during surgery. Of 2,065 splashes, 22.6% occurred during nursing activities, 19.1% during surgery, 14.1% during placement or removal of an intravenous line, and 12.0% during manipulation of a tracheotomy tube. The incidence rates of exposures were 8.9 per 100 hospital beds (95% confidence interval [CI], 8.7-9.0 exposures), 2.2 per 100 full-time equivalent physicians (95% CI, 2.4-2.6 exposures), and 7.0 per 100 full-timeequivalent nurses (95% CI, 6.8-7.2 exposures). Human immunodeficiency virus serological status was unknown for 2,789 (21.4%) of 13,041 patients who were the source of the blood and body fluid exposures. Conclusion: National surveillance networks for blood and body fluid exposures help to better document their characteristics and risk factors and can enhance prevention at participating medical centers.

Cost-effectiveness of HIV post-exposure prophylaxis in France. AIDS
ABSTRACT- Objective: To assess the cost-effectiveness of HIV post-exposure prophylaxis (PEP) in France. Methods: We used a decision tree to evaluate, from a society's perspective, the cost of PEP per quality-adjusted life-year (QALY) saved. We used 1999-2003 PEP surveillance data and literature-derived data on per event transmission probabilities, PEP efficacy and quality of life with HIV. HIV prevalence and lifetime cost of HIV/AIDS management in the HAART era were derived from French studies. We assumed that mean life expectancy in full health was 65 years among uninfected individuals and that the mean survival time after HIV infection was 22.5 years. The costs of PEP drugs and follow-up were derived from the French public sector. A 3% annual rate was used to discount future costs and effects. Results: During 1999-2003, PEP was prescribed to 8958 individuals (heterosexual sex: 47.6%; homosexual sex: 28.4%; occupational exposure: 23.4%; drug injection: 0.6%); of those, 2143 were exposed to a known HIV-infected source. PEP was estimated to prevent 7.7 infections and saved 64.5 QALY at a net cost of euro 5.7 million, resulting in an overall cost-effectiveness ratio of euro 88,692 per QALY saved. PEP was cost saving for 4.4% of cases and cost effective (< euro 50,000 per QALY) in a further 11.3% of cases. In contrast, 72 and 52% of prescriptions had a cost-effectiveness ratio exceeding euro 200,000 and euro 2 millions, respectively, per QALY saved. Conclusion: Overall, the French PEP programme is only moderately cost effective. PEP guidelines should be revised to target high-risk exposures better.

E. Risk of needlestick injuries by injection pens. Journal of Hospital
ABSTRACT: Injection pens are used by patients when auto-administering medication (insulin, interferon, apokinon etc.) by the subcutaneous route. The objective of this study was to evaluate the rate of injection pen use by healthcare workers (HCWs) and the associated risk of needlestick injuries to document and compare injury rates between injection pens and subcutaneous syringes. A one-year retrospective study was conducted in 24 sentinel French public hospitals. All needlestick injuries linked to subcutaneous injection procedures, which were voluntarily reported to occupational medicine departments by HCWs between October 1999 and September 2000, were documented using a standardized questionnaire. Additional data (total number of needlestick injuries reported, number of subcutaneous injection devices purchased) were collected over the same period. A total of 144 needlestick injuries associated with subcutaneous injection were reported. The needlestick injury rate for injection pens was six times the rate for disposable syringes. Needlestick injuries with injection pens accounted for 39% of needlestick injuries linked with subcutaneous injection. In all, 60% of needlestick injuries with injection pens were related to disassembly. Injection pens are associated with needlestick injuries six times more often than syringes. Nevertheless, injection pens have been shown to improve the quality of treatment for patients and may improve treatment observance. This study points to the need for safety-engineered injection pens.

preventive measures for accidental blood exposure in operating
theaters: A survey of 20 hospitals in Northern France. American Journal

ABSTRACT- Background: Accidental exposures to blood of body fluids (ABE) expose health care workers (HCW) to the risk of occupational infection. Objectives: Our aim was to assess the prevention equipment available in the operating theater (OT) with reference to guidelines or recommendations and its use by the staff in that OT on that day and past history of ABE. Methods: Correspondents of the Centre de Coordination de la Lutte contre les Infections Nosocomiales (CCLIN) Paris-Nord ABE Surveillance Taskforce carried out an observational multicenter survey in 20 volunteer French hospitals. Results: In total, 260 operating staff (including 151 surgeons) were investigated. Forty-nine of the 260 (18.8%) staff said they double-gloved for all patients and procedures, changing gloves hourly. Blunt-tipped suture needles were available in 49.1% of OT; 42 of 76 (55.3%) of the surgeons in these OT said they never used them. Overall, 60% and 64% of surgeons had never self-tested for HIV and hepatitis C virus (HCV), respectively. Fifty-five surgeons said they had sustained a total of 96 needlestick injuries during the month preceding the survey. Ten of these surgeons had notified of 1 needlestick injury each to the occupational health department of their hospital (notification rate, 10.4%). Conclusion: The occurrence of needlestick injury remained high in operating personnel in France in 2000. Although hospitals may improve access to protective devices, operating staff mindful of safety in the OT should increase their use of available devices, their knowledge of their own serostatus, and their ABE notification rate to guide well-targeted prevention efforts.

ABSTRACT- Objective: Midwives appear to be the health care workers exposed to the highest rates of bloodborne injury. In this paper - based on a national survey - we describe the bloodborne injuries occurring in this profession. Material and method: During the year 2003, 241 hospitals took part in a national survey of bloodborne injuries. Employees registered anonymous standardized reports of bloodborne events with the Occupational Medicine Unit. The data were processed by the coordination center for the fight against nosocomial infections (C. CLIN) which is in charge of the national analysis of all the events reported in this database. Results: 169 of the 6973 bloodborne events reported during 2003 (2.4%), were signed by midwives or midwife students. The first three most frequent accidents reported were: ocular projections during childbirth, pricks when repairing episiotomy, pricks or cuts when handling soiled instruments. Conclusion: Improving knowledge of risk as well as promotion of protection/prevention measures well adapted to this profession should be helpful in optimizing future attitudes.

ABSTRACT- Background: Factors that influence the risk for HCV infection after occupational exposure to hepatitis C virus (HCV) have not yet been determined. The objective of this study was to assess potential risk factors for Hepatitis C seroconversion after occupational exposure to HCV. Methods: We conducted a European matched case-control study from 01/01/1991 through 31/12/ 2002. Cases were Health Care Workers (HCWs) who were HCV seronegative at the time of exposure, sustained a documented exposure to HCV, and present documented HCV seroconversion temporally associated with the exposure. Control-HCWs had a documented exposure to HCV, were HCV seronegative at the time of exposure, and remained so at least 6 months later. Controls were matched to cases for the center and the time period of the exposure occurrence. Results: 60 cases and 204 controls were included. All cases were exposed to HCV-infected materials through percutaneous injuries. Those for whom information was available (61.6%) were exposed to viremic source patients. Multivariate conditional logistic regression analysis, in which HCV viral load was not introduced because of missing values, identified needle placed in the source patient's vein or artery (Odds Ratio [OR]=100.1; 95% Confidence Interval [CI]=7.3-1365.7), deep injury (OR=155.2; 95%CI=7.1-3417.2), and HCW's gender (M vs. F: OR=3.1; 95%CI=1.0-10.0) as risk factors for HCV infection. In univariate unmatched analysis the risk of HCV transmission was increased 11-fold (C195%=1.1-114.1) in HCWs exposed to sources with a viral load>6 log10 copies/mL when compared to sources with a HCV viral load<4 log10 copies/mL. Conclusion: The risk of HCV transmission after percutaneous exposure increases with a larger volume of blood, and a higher titer of HCV in the source patient's blood. The role of HCW's gender need to be further investigated. The results of this study have important implications for counselling and follow-up of HCWs after exposure.

devices for preventing percutaneous injuries related to phlebotomy
procedures in health care workers. American Journal of Infection
ABSTRACT- Background: Use of protective devices has become a common intervention to decrease sharps injuries in the hospitals; however few studies have examined the results of implementation of the different protective devices available. Objective: To determine the effectiveness of 2 protective devices in preventing needlestick injuries to health care workers. Methods: Sharps injury data were collected over a 7-year period (1993-1999) in a 3600-bed tertiary care university hospital in France. Pre- and postinterventional rates were compared after the implementation of 2 safety devices for preventing percutaneous injuries (PIs) related to phlebotomy procedures. Results: From 1993 to 1999, an overall decrease in the needlestick-related injuries was noted. Since 1996, the incidence of phlebotomy-related PIs has significantly decreased. Phlebotomy procedures accounted for 19.4% of all percutaneous injuries in the preintervention period and 12% in the postintervention period (RR, O.62; 95% CI, 0.51-0.72; P < .001). Needlestick-related injuries incidence rate decreased significantly after the implementation of the 2 safety devices, representing a 48% decline in incidence rate overall. Conclusions: The implementation of these safety devices apparently contributed to a significant decrease in the percutaneous injuries related to phlebotomy procedures, but they constitute only part of a strategy that includes education of health care workers and collection of appropriate data that allow analysis of residuals percutaneous injuries.

ABSTRACT- Au cours de la période 1990-2000, une surveillance a porté sur les accidents d'exposition au sang (AES) parmi les personnels de l'AP-HP. 24143 questionnaires standardisés ont été remplis par les médecins du travail au décours de chaque accident. D'après les résultats obtenus, les professionnels les plus exposés sont les infirmières (48 % des déclarations d'AES), les médecins et les étudiants en médecine (26 %). Entre 1995 et 2000, le taux d'incidence est passé chez les infirmières de 9,52 à 8,22 pour 100 équivalents temps pleins et pour l'ensemble des personnels paramédicaux de 4,10 à 3,97. L'évolution de la nature des accidents montre la prédominance persistante des piqûres et l'augmentation relative des projections. La fréquence des accidents percutanés les plus graves est en diminution: 69 % de blessures profondes en 1990 et 34 % en 2000 (p<0,001). La survenue d'accidents liés à des prélèvements a été divisée par deux. La recherche des sérologies VIH et VHC du patient-source s'est beaucoup développée. De plus, 99 % des victimes d'AES étaient protégées contre le VHB en 2000. Les taux de séroconversion VIH et VHC ont été estimés respectivement à 0,22 et 0,80 %. Parmi les facteurs de risque identifiés en 2000 figurent des éléments liés au contexte de travail (urgence, surcharge de travail, malade agité...). Les efforts de formation et d'organisation du travail doivent donc être poursuivis parallèlement à la mise à disposition des matériels de sécurité.

surveillance in France. [French] Hygiènes 2003;11:101-7.
ABSTRACT: La surveillance épidémiologique des accidents avec exposition au sang (AES) s'inscrit en France dans un cadre réglementaire et de bonnes pratiques. Articulée autour du Médecin du travail, cette surveillance doit faire appel à une méthodologie standardisée permettant une homogénéité du recueil et une comparabilité des données. Sur la base des travaux du GERES, les centres de coordination de lutte contre les infections nosocomiales ont mis en place depuis 1995 des réseaux multicentriques de surveillance des AES. L'analyse des résultats disponibles permet déjà une bonne approche descriptive des AES survenant dans les établissements de santé ainsi que le calcul de différents indicateurs d'incidence (par catégorie professionnelle, selon le nombre de lits et d'admissions ou encore en fonction de l'usage de certains dispositifs médicaux à risque). Ces différents travaux ont abouti à la création d'une méthodologie commune nationale de surveillance sous l'égide du réseau d'alerte, d'investigation et de surveillance des infections nosocomiales et à la mise en place en 2003 d'un recueil national de données.

Taskforce. Occupational blood and body fluids exposures in health care
workers: four-year surveillance from the Northern France network.
American Journal of Infection Control 2003;31:357-63.
ABSTRACT- The risk of accidental blood and body fluid (BBF) exposure is a daily concern for health care workers throughout the world, and various strategies have been introduced during the past decade to help reduce that risk. To assess the impact of multifocal reduction strategies introduced in hospitals affiliated with the Northern France network, we recently examined data from 4 years of BBF-exposure reports filed by network employees. A total of 7,649 BBF exposures were reported by health care workers to occupational medicine departments in 61 hospitals. Nurses and nursing students accounted for 4,587 (60%) of exposures, followed by nurses' aides and clinicians. Most (77.6%) of the reports were related to needlestick injury (NSI). In addition, we examined BBF exposure trends over time by analyzing data from 18 hospitals (29.5%) with data available for the time period of 1995 to 1998. These were assessed in nurses, who have the highest and most consistent reporting rate. We noted that the BBF-exposure incidence rate for all BBF exposures in nurses decreased from 10.8 to 7.7 per 100 nurses per year between 1995 and 1998 (P <.001), whereas the NSI rate decreased 8.9 per 100 nurses per year in 1995 to 6.3 in 1998 (P <.001). The percentage of NSIs that resulted from noncompliance with universal precautions also decreased significantly (P =.04). Widespread improvements in procedures and engineering controls were implemented in the Northern France network before and during the study period. Significant reductions were observed in reports of BBF exposures and NSIs, particularly in nurses. These findings are similar to those in other countries and reflect the overall improvement in the management of occupational risk of BBF in health care workers.

ABSTRACT: Although the risk of human immunodeficiency virus (HIV) infection through occupational exposures to blood has received considerable attention, relatively few studies have addressed blood exposure accidents (BEAs) among medical students. Guidelines for preventing needlestick injuries and administrating postneedlestick HIV prophylaxis are available, but these guidelines may be unfamiliar to medical students. This study investigates BEA exposure, BEA reporting, and use of universal precautions in a population of French medical students. Methods: An anonymous questionnaire was administered to medical students in the fourth, fifth, and sixth years of training at Nice University, France. Students answered questions regarding the use of gloves, handling of sharps, and personal exposure to needlestick injuries (BEAs). Information on risk reduction behaviors, number of BEAs, BEA reporting, and BEA management was collected. Data were analysed with Epi-Info 6.04a and BMDP software. Results: Of 237 registered students, 200 (84%) completed the questionnaire. The overall prevalence of BEA exposure was 24%, with 37% of sixth-year students reporting at least 1 BEA. The mean number of BEAs per student was 1.4. Wound suturing and arterial puncture for blood gas studies accounted for 58% and 20% of BEAs, respectively. The remaining 22% of the cases occurred during intramuscular (2 BEAs), intravenous (2) or lumbar (2 ) puncturing, and other procedures (5). Of students who recalled having experienced a BEA, 39% had reported the incident to hospital personnel. Students most frequently indicated their inability to influence the outcome (40%) as the reason for not reporting a BEA. Several students reported that they did not know whom to consult (20%) or had been advised against reporting (20%). Only 19% of students reported never recapping needles and always using a sharps container (Table 1). The decision to wear gloves was influenced by the procedure; most students used gloves for suturing, but not for intradermal or intramuscular injections. Of the students, 87% reported having received no information about universal precautions or BEAs during rotations. Discussion: Studies from several countries have found the prevalence of BEAs in medical students to be similar to that reported here. In this study, adherence to the universal precautions of using gloves and disposing of sharps was poor, suggesting a need to more carefully educate students on safe practices. Perhaps the most disquieting finding pertains to the reasons students frequently did not report BEAs. A surprising number of students cited their inability to influence the outcome as a chief reason for keeping silent. This pessimism is at odds with data showing that postexposure prophylaxis may result in substantial reduction in the risk of HIV transmission. Furthermore, our finding that many medical students may perceive that they are being dissuaded from reporting BEAs or do not know to whom they should report such incidents suggests that students need more occupational risk management training in medical student education.

ABSTRACT- A multicentric prospective trial was conducted to evaluate the frequency and kind of blood exposure in operating room. From march to june 1992, 3554 procedures were observed in 22 surgical units (visceral, orthopaedic and vascular), with 129 surgeons, 133 residents and 216 nurses. Statistic analysis was done on Epi Info 5 (CDC Atlanta) and EGRET (Statistic and Epidemiology Research Corporation, Seattle). 11.7% of procedures were the case for an incidental blood exposure: 4.2% for percutaneous exposure; 8.4% for cutaneous or mucosal exposure. Rates change with the surgical specialty. Surgeons were involved in 50.7% of percutaneous exposure and 58.7% of the cutaneous or mucosal exposures, especially when they were operators (respectively 2 and 5.6% person-act). A significative rate was founded between incidental blood exposure and the length of procedure, the sepsis character of the procedure, but not with emergency or number of globular units transfused. To diminish the incidental blood exposure and its risks, this data suggests three kinds of practice: a better work for vaccination; in our study 59% of surgeons declare an adequate vaccination against hepatitis B; a best operative hygiene, with knowing of risks factor of blood exposure, depending of the kind of procedure, changing between different units; the use of protections: non coated dressing, double gloving, ocular protection.

protective gloves in pathology--effective and cost-effective. Virchows
ABSTRACT - Cutting injuries and needle-stitch injuries constitute a potentially fatal danger to both pathologists and autopsy personnel. We evaluated such injuries in a large German institute of pathology from 2002 to 2007 and analysed the effect of the introduction of cut-resistant gloves on the incidence of these injuries. In the observation period, 64 injuries (48 cutting injuries and 16 needle-stitch injuries) were noted in the injury report books. Most injuries were located at the non-dominant hand, preferentially at the index finger and the thumb. Around one fifths of the injuries were at the side of handedness. The average number of injuries per month was 1.22 for the 50 months prior to the introduction of cut- resistant gloves, more than seven times higher than after their introduction (0.158; 19 months; p < 0.001). Considering the medical and administrational costs of such injuries, cut-resistant protective gloves are an effective and cost-effective completion of personal occupational safety measures in surgical pathology and autopsy. We strongly recommend the use of such gloves, especially for autopsy personnel.

ABSTRACT- Needlestick injuries routinely occur in everyday clinical practice. Adequate instruction of employees in health care and correct prophylaxis against exposure could conspicuously reduce the incidence. Successful prevention of chronic infectious diseases comprises strict vaccination plans and substantial knowledge of post-exposure prophylaxis. The introduction of self-securing cannulas and injection instruments represents an important technological advance.

Determination of risk of infection with blood-borne pathogens following
a needlestick injury in hospital workers. Ann Occup Hyg 2008; published
online July 29, 2008.
ABSTRACT - Objectives: Our paper measures the prevalence of hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV) in patients at the University Hospital of Frankfurt/Main, and correlates the prevalence with risk factors for exposure to and infection of healthcare workers (HCWs). Individual risk assessments were calculated for exposed HCWs. Methods: Survey of patients admitted to a German University Hospital. Markers for HBV, HCV and HIV were studied and evaluated statistically. Data on needlestick injuries (NSIs) among HCWs were correlated with the prevalence of infectious patients. Results: The HBV, HCV and HIV prevalence among patients at the University Hospital were 5.3% (n = 709/13 358), 5.8% (n = 1167/20 163) and 4.1% (n = 552/13 381), respectively. Our results indicate that the prevalence of blood-borne infections in patients was about nine times higher for HBV, approximately 15 times higher for HCV and approximately 82 times higher for HIV than in the overall German population. The highest risk of acquiring a blood-borne infection via NSI was found in the department of internal medicine due to increased prevalence of blood-borne pathogens in patients under treatment. Conclusions: While accidental NSIs were most frequent in surgery, the nominal risk of blood-borne virus infection was greatest in the field of internal medicine. The study underlines the importance of HBV vaccinations and access to HIV-post-exposure prophylaxis for HCWs as well as the use of anti-needlestick devices.

needlestick injury: must the index patient be informed?][Article in
German] Dtsch Med Wochenschr 2008;133(28-29):1517-20.
ABSTRACT - As a current case of needlestick injury (NSI) has demonstrated, it is obvious that in clinical practice there is often uncertainty about the procedure if the index patient refuses a blood test or is not able to give his/her consent. The question about the legality of implementing HBV, HCV and HIV testing after NSI is commented on from different points of view: occupational medicine, infection control, virology and the legal system. The testing of the index patient - without his/her consent - seems to be appropriate. The protection of health care workers should be given priority over the right of the index patient "not wanting to know" about his/her infection status.
2008;42(7):742-5.ABSTRACT: Medical students are at risk of occupational exposure to blood-borne viruses following needlestick injuries (NSIs) during medical school. The reporting of NSIs is an important step in the prevention of further injuries and in the initiation of early prophylaxis or treatment. The objective of this study was to describe the mechanisms whereby medical students experience occupational percutaneous blood exposure through NSIs and to discuss rational strategies for prevention. Methods: Incidents of exposure to blood-borne pathogens among medical students at a large German university were analysed. Year 6 medical students completed a written survey immediately before the clinical part of their training began, describing incidents that had occurred during the previous 5 years. Results In our study, 58.8% (183/311) of participating medical students recalled at least one NSI that had occurred during their studies. Overall, 284 NSIs were reported via an anonymous questionnaire. Discussion: Occupational exposure to blood is a common problem among medical students. Efforts are required to ensure greater awareness of the risks associated with blood-borne pathogens among German medical students. Proper training in percutaneous procedures and how to act in the event of injury should be given in order to reduce the number of injuries.

[Injuries from needles contaminated with hepatitis C virus: how high is
the risk of seroconversion for medical personnel really?][in German]
Der Internist (Berlin) 2007;48:1165-72.
ABSTRACT- The risk of infection after injury with a needle contaminated with hepatitis C virus (HCV) is thought to be about 3%, but this assumption is mainly based on studies published in the 1990's, which were limited by small sample sizes and insensitive HCV-RNA assays. We therefore investigated needle injuries at the Hannover Medical School over a period of 6 years and performed a systematic review of the literature identifying 22 studies with a total of 6,956 injuries with HCV contaminated needles. Between 2000 and 2005, 1,431 occupational injuries were reported at our institution and two-thirds were needle injuries. Index patients were known to be HCV infected in 166 cases but there were no cases of HCV seroconversion during follow-up. Analysis of published data showed seroconversion rates of 0-10.3% with a mean of 0.75% (52/6,956). The risk of acute HCV infection was lower in Europe with 0.42% compared to Eastern Asia with 1.5% of cases where an HCV viremia was reported during follow-up. In summary, the risk of acquiring an HCV infection after a needlestick injury is lower than frequently reported. Worldwide differences in HCV seroconversion rates suggest that genetic factors might provide some level of natural resistance against HCV. Future studies should address not only the frequency of acute hepatitis but also factors associated with a higher risk of becoming HCV infected.

virus (HCV)-specific T cells by needle stick injury in the absence of
HCV-viraemia. European Journal of Clinical Investigation
ABSTRACT- Background: The risk of hepatitis C virus (HCV) infection after occupational exposure is low with seroconversion rates between 0 and 5%. However, factors associated with natural resistance against HCV after needle stick injury are poorly defined. HCV-specific T-cell responses have been described in cross-sectional studies of exposed HCV-seronegative individuals. Materials and methods: In this study, we prospectively followed 10 healthcare professionals who experienced an injury with an HCV-contaminated needle. Blood samples were taken on the day or the day after the event and at different time points during follow-up for up to 32 months. HCV-specific T-cell responses were investigated directly ex vivo and in T-cell lines. Results: None of the individuals became positive for HCV-RNA in serum tested with the highly sensitive transcription-mediated amplification (TMA)-assay or in peripheral blood mononuclear cells (PBMC). All of them remained anti-HCV negative throughout follow-up. At the time of injury, HCV-specific CD4+ T-cell responses were already detectable in two individuals and became detectable thereafter in three additional persons. Transient HCV-specific CD8+ T-cell responses developed in two HLA-A2 positive patients, which became negative until the most recent follow-up after 5 and 17 months, respectively. Conclusion: We demonstrate the development of HCV-specific T cells in HCV-exposed individuals after needle stick injury indicating subinfectious exposure to HCV. T-cell immunity against HCV may contribute to the low prevalence of HCV in medical healthcare professionals in Western countries.

and prevention of needlestick injuries among health care workers in a
German university hospital. International Archives of Occupational and

ABSTRACT- Objective: Health care workers (HCWs) are exposed to bloodborne pathogens, especially hepatitis B (HBV), hepatitis C (HCV), and human immunodeficiency virus (HIV) through job-related risk factors like needlestick, stab, scratch, cut, or other bloody injuries. Needlestick injuries can be prevented by safer devices. Methods: The purpose of this study was to investigate the frequency and causes of needlestick injuries in a German university hospital. Data were obtained by an anonymous, self-reporting questionnaire. We calculated the share of reported needlestick injuries, which could have been prevented by using safety devices. Results: 31.4% (n = 226) of participant HCWs had sustained at least one needlestick injury in the last 12 months. A wide variation in the number of reported needlestick injuries was evident across disciplines, ranging from 46.9% (n = 91/194) among medical staff in surgery and 18.7% (n = 53/283) among HCWs in pediatrics. Of all occupational groups, physicians have the highest risk to experience needlestick injuries (55.1%-n = 129/234). Evaluating the kind of activity under which the needlestick injury occurred, on average 34% (n = 191/561) of all needlestick injuries could have been avoided by the use of safety devices. Taking all medical disciplines and procedures into consideration, safety devices are available for 35.1% (n = 197/561) of needlestick injuries sustained. However, there was a significant difference across various medical disciplines in the share of needlestick injuries which might have been avoidable: Pediatrics (83.7%), gynecology (83.7%), anesthesia (59.3%), dermatology (33.3%), and surgery (11.9%). In our study, only 13.2% (n = 74/561) of needlestick injuries could have been prevented by organizational measures. Conclusion: There is a high rate of needlestick injuries in the daily routine of a hospital. The rate of such injuries depends on the medical discipline. Implementation of safety devices will lead to an improvement in medical staff's health and safety.

ABSTRACT- This paper will examine the experience of Needle Stick Injuries (NSI) in Germany. There is evidence that these experiences have relevance for the whole of Europe. The protective measures described in this paper are important for the safety of all health care workers. This paper will describe incidents of NSI with reference to sero-conversion after the incident. The protection of health care workers is of prime importance and this paper will discuss the most successful methods of protection. The paper will examine briefly the cost of these protective measures.

SUMMARY- As of August 2006, [German] healthcare employees must be better protected from needlestick injuries. For with the amendment to the Technical Rules for Biological Agents - TRBA 250 (Technischer Regel für Biologische Arbeitsstoffe - TRBA 250), the use of so-called safety instruments for specific fields of work - mostly unnoticed by the majority of people - has been made mandatory. A current legal opinion now makes it clear that the new TRBA 250 turns the "should-regulation" into a "must regulation". It also emphasizes that safety instruments are not only obligatory in hospitals, but in doctors' offices as well. Should a doctor or employer fail to abide by this regulation, they could face monetary fines or even imprisonment for up to three years in the event of an injury and/or claim.

ABSTRACT: Recent transmission of dengue viruses has increased in tropical and subtropical areas and in industrialized countries because of international travel. We describe a case of nosocomial transmission of dengue virus in Germany by a needlestick injury. Diagnosis was made by TaqMan reverse transcriptionpolymerase chain reaction when serologic studies were negative.

ABSTRACT: Two hundred and eighty-six occupational transmissions of HIV had been reported worldwide by the end of 1997 (1). A third of these cases (95), usually associated with seroconversion after a specific occupational exposure, were classified as definite occupationally acquired infections. The remaining infections (191) were classified as possibly occupationally acquired. Three of the 95 definite (2,3) and 22 of the 191 possible occupationally acquired HIV infections occurred in German health care workers (1).

needle-stick-injuries during abdominal closure][Article in German]
Zentralbl Chir. 1996;121(1):30-4.
SUMMARY: A randomized study is presented, which compares closure of laparotomy with 2 different needles (sharp: HR48, blunt: HR48PP = protect point). Handling and glove perforation rate is to be compared. 400 gloves in 100 laparotomies have been tested. Slightly more effort was reported from the surgeon to perforate the fascia with the blunt needle, but there was also a significantly lower perforation rate in the glove of his non-dominant hand. To avoid a contamination during operation the use of blunt needles has to be recommended.

Incidents of the Health Care Personnel in a Newly Founded Tertiary
Hospital: A Prospective Study. PLoS ONE 2007; 2(2):e194. (Published
online 2007 February 7.)
ABSTRACT- Background: Percutaneous exposure incidents (PEIs) and blood splashes on the skin of health care workers are a major concern, since they expose susceptible employees to the risk of infectious diseases. We undertook this study in order to estimate the overall incidence of such injuries in a newly founded tertiary hospital, and to evaluate possible changes in their incidence over time. Methodology/Principal Findings: We prospectively studied the PEIs and blood splashes on the skin of employees in a newly founded (October 2000) tertiary hospital in Athens, Greece, while a vaccination program against hepatitis B virus, as well as educational activities for avoidance of injuries, were taking place. The study period ranged from October 1, 2002 to February 28, 2005. Serologic studies for hepatitis B (HBV) and C virus (HCV) as well as human immunodeficiency virus (HIV) were performed in all injured employees and the source patients, when known. High-titer immunoglobulin (250 IU anti-HBs intramuscularly) and HBV vaccination were given to non-vaccinated or previously vaccinated but serologically non-responders after exposure. Statistical analysis of the data was performed using Mc Nemar's and Fisher's tests. 60 needlestick, 11 sharp injuries, and two splashes leading to exposure of the skin or mucosa to blood were reported during the study period in 71 nurses and two members of the cleaning staff. The overall incidence (percutaneous injuries and splashes) per 100 full-time employment-years (100 FTEYs) for high-risk personnel (nursing, medical, and cleaning staff) was 3.48, whereas the incidence of percutaneous injuries (needlestick and sharp injuries) alone per 100 FTEYs was 3.38. A higher incidence of injuries was noted during the first than in the second half of the study period (4.67 versus 2.29 per 100 FTEYs, p=0.005). No source patient was found positive for HCV or HIV. The use of high-titer immunoglobulin after adjustment for the incidence of injuries was higher in the first than in the second half of the study period, although the difference was not statistically significant [9/49 (18.37%) vs 1/24 (4.17%), p=0.15]. Conclusions: Our data show that nurses are the healthcare worker group that reports most of PEIs. Doctors did not report such injuries during the study period in our setting. However, the possibility of even relatively frequent PEIs in doctors cannot be excluded. This is due to underreporting of such events that has been previously described for physicians and surgeons. A decrease of the incidence of PEIs occurred during the operation of this newly founded hospital.

care workers in a Greek general hospital. Occupational Medicine
(Oxford, England) 1999;49:423-6.
ABSTRACT- Between July 1990 and June 1996, 284 exposures to infectious material were reported by 247 health care workers (HCWs) at AHEPA University Hospital, Thessaloniki, Greece, representing an overall rate of 2.4% reported injuries per 100 HCWs/year. Nurses reported the highest rates of incidents (3.0%) and in all but one working group women exhibited higher injury rates per year than male HCWs. Young workers (21-30 years old) were primarily affected in incidents (P < 0.001). Needles were the most common implement causing injury (60.6%) and resheathing of used needles as well as garbage collection were common causes of injury. None of the HCWs seroconverted in exposures where immune status to blood-borne pathogens was estimated. Efforts by the infection control committee need to be more intense, in order to increase the rate of reported staff injuries. This will facilitate identification of unsafe practices and provide more adequate preventive measures.

ABSTRACT- Needlestick injury is the most important risk event for human immunodeficiency virus (HIV) and hepatitis B Virus (HBV) transmission to health-care workers. We examined phlebotomy practices, the frequency of needle stick injuries, the reporting of such injuries and hepatitis B status among interns in St James's Hospital during a six month period. This study took the form of a questionnaire. The response rate was 100%. 72% had at least one needlestick injury during this time period, 23% had injuries from known HIV sero-positive or hepatitis B surface antigen positive patients, less than 5% of all injuries were reported and only 41% of interns were definitely hepatitis B immune. The majority (77%) resheated needles by hand.

and mucocutaneous exposures in nursing students: an Italian
observational study. Journal of Nursing Scholarship
ABSTRACT - Purpose: To investigate occupational exposures to biological material potentially infected by blood-borne viruses in nursing student population during the course years. Design and methods: An observational retrospective study was designed. Data were collected in May 2007. Two-thousand-two-hundred-fifteen nursing students from the 3 years of degree course were enrolled in the four Italian universities. A structured questionnaire was constructed and was given out unannounced to nursing students in four universities on a randomly chosen day. The likelihood of association between nursing student exposure and certain assumed risk factors was measured. Findings: The exposure risk is associated with each study year of nursing students. Specifically, the probability of accidental exposure is reduced significantly with the increase of clinical skills during the training period. The risk for exposure in the 1st year students appears significantly higher than in those of the next years (odds ratio [OR] 1.465; 95% confidence interval [CI] 1.105-1.943). Data highlighted a gradual increase of bio-safety knowledge in nursing students from the 1st to the 3rd years of study. However, a statistically significant association exists only between awareness of a correct use of gloves and exposure risk (OR 0.435; 95%CI 0.227-0.834). Mucocutaneous exposures are more frequent than percutaneous exposures (62.2%), and the hollow-bore needle is the device most often involved. In 42.5% of cases, accidental exposures occurred when nursing students are working alone in a medical ward or surgery area. Conclusions: During their clinical training, nursing students can encounter a real risk for percutaneous and mucocutaneous exposures to blood potentially infected with blood-borne viruses. However, this risk is reduced with an increase in clinical skills. Clinical relevance: Results show that some new strategies are necessary for exposure risk reduction such as development of simulation laboratories for nursing practice and the adequate presence of tutors in clinical training education.

hepatitis B vaccination coverage among healthcare workers in Italy 10
years apart. Dig Liver Dis 2008;40(4):275-7.
ABSTRACT - BACKGROUND: In Italy, vaccination against hepatitis B virus infection was strongly recommended for healthcare workers since 1985. Update findings on vaccination coverage are lacking. AIM: To assess current vaccination coverage against hepatitis B in this job category. METHODS: In 2006, 1,632 healthcare workers randomly selected in 15 Italian public hospitals completed a self-administered precoded questionnaire. RESULTS: The overall vaccination coverage was 85.3%, a figure higher than the 64.5% observed in 1996. Vaccine coverage showed a significant downtrend (p<0.01) from the Northern (93.1%) to the Southern (77.7%) areas. Logistic regression analysis showed that residence in the North (Odds ratio 4.2; 95% confidence interval 2.6-6.7) and youngest age (Odds ratio 4.5; 95% confidence interval 2.6-7.8), both were independent predictors of vaccine acceptance. CONCLUSIONS: Ten years apart, vaccine coverage has markedly increased, closely paralleling the downtrend in the incidence of acute B hepatitis among healthcare workers in Italy.

ABSTRACT- Background: Several studies have investigated both the frequency and modality of occurrence of occupational exposure of health-care workers to blood-borne pathogens. At the moment no complete epidemiological data are available covering the hospitals of an entire Region. Objectives and methods: To describe the characteristics of mucocutaneous and percutaneous exposure to body fluids of the healthcare workers in 47 out of the 56 public hospitals (90% of a total 15,000 beds, 28,000 health-care workers full time equivalent) in Piedmont, Northern Italy (4.5 million inhabitants) over a three-year period (1999-2002), using SIROH (Studio Italiano Rischio Occupazionale da HIV) model to collect the data. Results and conclusions: 5174 percutaneous injuries (12.7/100 beds) and 1724 mucocutaneous exposure (4.1/100 beds) were recorded. Surveillance data were similar to those collected in other multi-hospital studies. The variability of rates between hospitals was high, most likely due to the amount of underreporting. The categories most at risk of percutaneous and mucocutaneous exposure were, respectively, surgeons (9.3/100 surgeons) and midwives (2.9/100 midwives). Needles (syringe, winged steel, suture) were the medical devices most frequently involved in percutaneous injuries, 60% of which occurred after the use of such devices. Eighty-three per cent of healthcare workers had been HBV-vaccinated versus only 45% of cleaning staff. After percutaneous injuries with exposure to an HIV positive source only 40% of those exposed received post-exposure prophylaxis; in the case of mucocutaneous exposure the rate was 11%. We recorded 2 seroconversions following occupational exposure to an HCV positive source (risk of seroconversion: 0,2%). In order to implement preventive programmes the use of safety devices, an increase in the number of HBV-vaccinated contract workers, the use of chemoprophylaxis for HIV exposure, and the use of protective equipment are deemed necessary.

[Article in Italian]
SUMMARY: Needlestick injuries since 2004 to 2006 were evaluated in University healthcare workers that reported an accident by point, sharp or mucosal contamination. During this period, 497 accidents with instruments contamined with biological fluids were reported. The injuries were most frequent between 9 a.m. and 1 p.m. (233 accidents). There is no difference during the week (excluding Saturday and Sunday), whereas February, May, June, and July were the months at risk. The most of accidents were during the first four hours of the job. They were identified 423 known sources and compliance with follow-up was evaluated. Only 26.3% of subjects injured with known hepatitis B source, 32.3% with known HIV source, and 40% with known HCV source completed follow-up. Fortunately, no seroconversion was observed. The lack of compliance with the follow-up, also if the source is known, needs to stimulate healthcare workers to subject to the protocols and to follow the standard procedure to prevent the needlestick injuries.

ABSTRACT- A 47-year-old woman was pricked accidentally with a needle previously used for a neurosyphilitic man. At day 0 she had no positive laboratory results for the infection, while the source, at day 1, had TPHA positive, but no post-exposure prophylaxis (PEP) against syphilis was prescribed. The subject missed the day 30 follow-up, and underwent our visit at day 90, when she showed no clinical signs, but she seroconverted (VDRL = positive 1/2; TPHA = positive 1/320; FTA-Abs IgG and IgM = present). She started antibiotic therapy, and currently her serological status is VDRL = positive 1/2, TPHA = positive 1/160, FTA-Abs IgM = negative.

sharps injuries among nursing students: an emerging occupational risk.]
[Article in Italian]
SUMMARY: The biohazard represents a major occupational risk among workers in the health sector, this risk is not only exclusive for healthcare workers but involve also nursing students. The study reports data of a survey on injuries from accidental puncture in a group of 223 students of the third year of Nursing of Bari University. The 18% of students say they have suffered over the past 12 months an accidental puncture with sharp instruments. The cutting device most frequently involved is the needle from the syringe and insulin. The most at risk are the recovered and disposal of the needle. The biohazard in training is further compounded by factors such as lack of experience and skill manuals consolidated combined with a non perception of the risk. In the obligation of protection, training and information to students of Nursing, the University must implement programs aimed at both knowledge of the risks to which they are exposed, as well as security procedures to contain an emerging risk, which one of injury from sharp instruments, which are exposed young students not yet in employment.

SUMMARY - Occupational injuries represent an important risk factor in the nurses. In this paper we have studied the characteristics of the phenomenon in a group of nursing school students of one University of the Lazio. The results show an elevated frequency of the phenomenon, characterized exclusively from biological accidents and the necessity to plan preventive measures, insisting, mainly on needles and sharps manipulation.

ABSTRACT: The aim of the study was to examine the preventability of percutaneous injuries either through the adoption of correct behaviour or by the use of needles with safety features. We analysed the report forms of occupational needlestick or sharps injuries in a sample of healthcare workers exposed to the risk of percutaneous injuries in the period between 1 June 2000 and 31 May 2001; the forms were returned to the regional SIROH (Italian Study on Occupational Exposure to HIV) centre in which all hospitals of the Piemonte region (Italy) participate. Percutaneous injuries caused by needles (injection, phlebotomy, infusion), suture needles and scalpels were analysed; three samples were extracted according to the type of device that caused the injury. In the sample of 439 needlestick-related percutaneous injuries, 74% were caused by incorrect health worker behaviour and 26% were unpreventable, seventy-nine percent of accidents caused by incorrect behaviour and 24% of accidents could have been prevented by using needles with safety features. In the sample of 221 suture needle and 114 scalpel injuries, incorrect health worker behaviour was identified in 26.2% and 14%, respectively, and unpreventable causes in 73.8% and 50.9%, respectively. A high rate of percutaneous injuries, especially those involving needles for injection, phlebotomy, infusion, and scalpels, could be prevented by adopting safe work behaviour practices and using personal protection equipment. The introduction of devices with safety features could lead to a significant reduction in the number of injuries from needles.

effects of HAART: decreasing and changing occupational exposure to
HIV-infected patients. Journal of Biological Regulators &

ABSTRACT- To investigate percutaneous exposures to HIV in the highly active antiretroviral therapy (HAART) era, we performed an analysis of all percutaneous exposures reported from January 1994 to December 1998 in 18 Italian acute-care hospitals. Frequency and rate per 100 prevalent AIDS cases of HIV exposures decreased by 40% (from 4.3% to 2.6%, and from 1.0% to 0.6%, respectively; p<0.001), which were mainly those related to the insertion/manipulation of peripheral vascular access devices (from 7.2% to 4.8%; p=0.05). We conclude that the benefits of HAART have changed the complexity of care required and therefore, the number and type of procedures performed on HIV patients that place the HCW at risk of injury.

workers in hospital. Digestive & Liver Disease
ABSTRACT- Recommendations are made for controlling the transmission of the hepatitis B and hepatitis C viruses from healthcare workers to patients. These recommendations were based both on the literature and on experts' opinions, obtained during a Consensus Conference. The quality of the published information and of the experts' opinions was classified into 6 levels, based on the source of the information. The recommendations can be summarised as follows: all healthcare workers must undergo hepatitis B virus vaccination and adopt the standard measures for infection control in hospitals; healthcare workers who directly perform invasive procedures must undergo serological testing and the evaluation of markers of viral infection. Those found to be positive for: 1) HBsAg and HBeAg, 2) HBsAg and hepatitis B virus DNA, or 3) anti-hepatitis C virus and hepatitis C virus RNA must abstain from directly performing invasive procedures; no other limitations in their activities are necessary. Infected healthcare workers are urged to inform their patients of their infectious status, although this is left to the discretion of the healthcare worker; whose privacy is guaranteed by law. If exposure to hepatitis B virus occurs, the healthcare worker must undergo prophylaxis with specific immunoglobulins, in addition to vaccination.

workers in the AIDS era. Journal of Biological Regulators and
Homeostatic Agents 2001;15:243-8.
ABSTRACT- Laboratory workers are at occupational risk of exposure to microrganisms that cause a wide variety of diseases, from inapparent to life-threatening ones. Principal routes of transmission include percutaneous and permucosal inoculation (comprising clinical inapparent cutaneous or mucosal exposure to blood or blood products), inhalation, and ingestion. The appearance of the Acquired Immunodeficiency Syndrome (AIDS) epidemic and the first reports of occupational Human Immunodeficiency Virus (HIV) infections in health care workers resulted in high anxiety among laboratory workers. Indeed, 21% of worldwide documented cases of occupational HIV infection occurred among laboratory workers. Research laboratories pose the highest risk of infection. Safe methods for managing infectious agents ("containment") in the laboratory setting include laboratory practice and technique, safety equipment, and facility design. Infection control in the laboratory setting should take into account adherence to guidelines (biosafety levels), education and training, and the development of safety products designed to reduce the risk of exposure.

in healthcare workers: an Italian study of occupational risk of HIV and
other blood-borne viral infections. British Journal of Infection
ABSTRACT- From January 1994 to December 1999, 44 hospitals were enrolled in the Studio Italiano Rischio Occupazionale da HIV (SIROH), an Italian hospital network established in 1986 to study, monitor and prevent the risk of occupational transmission of blood-borne pathogens in the healthcare setting. During the study period, 21,118 percutaneous exposure and 6,400 mucocutaneous exposures were reported. Nurses were the most exposed (57%), and had the highest combined (percutaneous and mucocutaneous) exposure rates in all working areas, ranging from 15.1 per 100 full-time equivalent positions in general surgery to 9.5% in medical specialities. Among percutaneous exposures, 66.2% involved a hollow-bore (HB) needle device. Device-specific exposure rates per 100,000 devices used for disposable syringes, winged steel needles, vacuum tube phlebotomy sets, and IV catheters (90% of involved HB devices) were higher for those devices with a more complicated design. Twelve cases of occupational infection were detected; the seroconversion rates following percutaneous and mucocutaneous exposures to HIV, HCV and HBV were all <0.5%. No cases of infection followed non-intact skin exposure. Our study shows that the implementation of standardised program by a network of acute care hospitals provides us with the ability to address many important questions concerning the safety of HCWs.

ABSTRACT- Objective: To analyze the rate of occupational exposure to blood and body fluids from all sources and specifically from human immunodeficiency virus (HIV)-infected sources among hospital workers, by job category and work area. Design: Multicenter prospective study. Occupational exposure data (numerator) and full-time equivalents ([FTEs] denominator) were collected over a 5-year period (1994-1998) and analyzed. Setting: 18 Italian urban acute-care hospitals with infectious disease units. Results: A total of 10,988 percutaneous and 3,361 mucocutaneous exposures were reported. The highest rate of percutaneous exposure per 100 FTEs was observed among general surgery (11%) and general medicine (10.6%) nurses, the lowest among infectious diseases (1.1%) and laboratory (1%) physicians. The highest rates of mucocutaneous exposure were observed among midwives (5.3%) and dialysis nurses (4.7%), the lowest among pathologists (0%). Inadequate sharps disposal and the prevalence of sharps in the working unit influence the risk to housekeepers. The highest combined HIV exposure rates were observed among nurses (7.8%) and physicians (1.9%) working in infectious disease units. The highest rates of high-risk percutaneous exposures per 100 FTE were again observed in nurses regardless of work area, but this risk was higher in medical areas than in surgery (odds ratio, 2.1; 95% confidence interval, 1.9-2.5; P<.0001). Conclusion: Exposure risk is related to job tasks, as well as to the type and complexity of care provided in different areas, whereas HIV exposure risk mainly relates to the prevalence of HIV-infected patients in a specific area. The number of accident-prone procedures, especially those involving the use of hollow-bore needles, performed by job category influence the rate of exposure with high risk of infection. Job- and area-specific exposure rates permit monitoring of the effectiveness of targeted interventions and control measures over time.

Italiano Rischio Occupazionale HIV. Risk of HIV and other blood-borne
infections in the cardiac setting: patient-to-provider and
provider-to-patient transmission. Annals of the New York Academy of
ABSTRACT- Health care workers (HCWs) face a well-recognized risk of acquiring blood-borne pathogens in their workplace, in particular hepatitis B and C viruses (HBV/HBC) and human immunodeficiency virus (HIV). Additionally, infected HCWs performing invasive exposure-prone procedures, including in the cardiac setting, represent a potential risk for patients. An increasing number of infected persons could need specific cardiac diagnostic procedures and surgical treatment in the future, regardless of their sex or age. The risk of acquiring HIV, HCV, HBV infection after a single at-risk exposure averages 0.5%, and 1-2%, and 4-30%, respectively. The frequency of percutaneous exposure ranges from 1 to 15 per 100 surgical interventions, with cardiothoracic surgery reporting the highest rates of exposures; mucocutaneous contamination by blood-splash occurs in 50% of cardiothoracic operations. In the Italian Surveillance (SIROH), a total of 987 percutaneous and 255 mucocutaneous exposures were reported in the cardiac setting; most occurred in cardiology units (46%), and in cardiovascular surgery (44%). Overall, 257 source patients were anti-HCV+, 54 HBsAg+, and 14 HIV+. No seroconversions were observed. In the literature, 14 outbreaks were reported documenting transmission of HBV from 12 infected HCWs to 107 patients, and 2 cases of HCV to 6 patients, during cardiothoracic surgery, especially related to sternotomy and its suturing. The transmission rate was estimated to be 5% to 13% for HBV, and 0.36% to 2.25% for HCV. Strategies in risk reduction include adequate surveillance, education, effective sharps disposal, personal protective equipment, safety devices, and innovative technology-based intraoperative procedures.

ABSTRACT- Health care workers (HCWs) face a serious risk of acquiring bloodborne infections, in particular hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV), all of which are associated with significant morbidity and mortality. In 1986 the coordinating centre of the Italian Study on Occupational Risk of HIV Infection (Studio Italiano Rischio Occupazionale da HIV, SIROH) began a multicentre prospective study to estimate the risk of transmission of HIV and other bloodborne pathogens to HCWs following an occupational exposure to blood and other body materials, and to identify high risk devices, procedures, and jobs in the health care setting. The coordinating centre has managed the Italian registry of antiretroviral post exposure prophylaxis in order to monitor the use of and the short term toxicity of zidovudine (ZDV) since 1990, and, since 1995, of antiretroviral combination prophylaxis. This paper describes the SIROH and presents results that illustrate its potential.

ABSTRACT- In 1991, to assess the risk of occupational exposure to blood or other body fluids in health-care workers (HCWs) working in the dialysis setting, properly trained interviewers used standardized questionnaires asking the 583 HCWs employed in 19 Italian dialysis units to recall exposures sustained in the previous year. On a total of 208,498 dialyses performed in the previous year, 105 (5 per 10,000 dialyses) needlesticks, and 579 (28 per 10,000 dialyses) skin/mucous membrane contaminations were recalled. Recapping injuries were recalled in 38 cases (1.8 per 10,000 dialyses), but 67 needlestick injuries (4.1 per 10,000 dialyses) occurred during other circumstances (p = 0.006). The highest rate of skin/mucous membrane contaminations were recalled during the dialysis patient care, but more than one third of exposures occurred in other circumstances (break in blood circuit, disposal, contamination with blood-soiled equipment. To minimize the risk of occupational exposure to blood efforts must continue to increase compliance with Universal Precautions; moreover, needle designs incorporating safety features to prevent sticks are needed.

ABSTRACT- A seroprevalence survey of hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV), was conducted using serum samples obtained from 5813 health care workers (HCWs) in five public hospitals in the Latium region of Italy, during the 1985 vaccination campaign against HBV. The seroprevalences of HBV, HCV and HIV were 23.3% [95% confidence interval (CI) = 22.3-24.4%], 2% (95% CI = 1.6- 2.4%) and 0.07% (95% CI = 0.001-0.13%), respectively. In a logistic regression model, sex, increasing age, all job categories vs. physicians, dental treatment in the previous six months, and needlestick injury during the previous year were significantly associated with HBV. Conversely, no occupational and community risk factors, but only history of blood transfusion were significantly associated with HCV. Nevertheless, the documented risk of HCV as well as of HIV transmission through percutaneous and mucocutaneous exposure to blood and body fluids should lead to continued efforts to minimize risks of infection by enhancing the compliance of HCWs with vaccination against HBV and adherence to infection control measures, and by introducing safer devices and techniques.

Italian Multicenter Study on Nosocomial and Occupational Risk of
Infections in Dialysis. American Journal of Infection Control
ABSTRACT- Background: The dialysis setting has been recognized as a high-risk environment for transmission to both patients and health care personnel of blood-borne infections, such as hepatitis B virus, hepatitis C virus, and HIV. Methods: A seroprevalence survey of HIV, hepatitis B virus, and hepatitis C virus infection among 1002 patients and a subsequent 1-year surveillance study of percutaneous injuries and skin and mucous membrane contaminations were carried out among 527 health care workers in nine Italian dialysis units. The risks of occupational acquisition of HIV, hepatitis B virus, and hepatitis C virus infections among health care workers were calculated according to a deterministic model. Results: HIV antibody, hepatitis B surface antigen, and hepatitis C antibody prevalences among patients were 0.1%, 5.1%, and 39.4%, respectively. A total of 67 percutaneous injuries, 29 mucous membrane contaminations, and 271 skin contaminations were reported by health care workers. The risk of acquiring infection was calculated to be 4000 and 8000 times lower for HIV than for hepatitis B and C, respectively. Conclusions: The risks of infection with HIV, hepatitis B, and hepatitis C for health care workers at dialysis units differ greatly and depend on the demographic profile and medical history of patients undergoing dialysis. To minimize the risk of exposure to HIV and other blood-borne pathogens, efforts must continue to increase compliance with universal precautions. Needle designs incorporating safety features and improvements in dialysis equipment design are also needed to avoid potential exposure.

after occupational exposures in health care workers. American Journal
of Infection Control 1995;23:273-7.
ABSTRACT- Background: To determine the incidence of hepatitis C virus (HCV) seroconversion, health care workers reporting an occupational exposure with blood or other risk-prone body materials from a patient known to be seropositive for HCV antibody were enrolled. Methods: HCV seroconversion within 6 months of a reported exposure was assessed by second-generation enzyme immunoassay and immunoblot assay. Results: From January 1992 through December 1993, 331 (51%) hollow-bore needlesticks, 105 (16.5%) suture needle or sharp object injuries, 85 (13%) mucous membrane contaminations, and 125 (19.5%) skin contaminations were reported. Four HCV seroconversions were observed after hollow-bore needlesticks (1.2%; 95% CI 0.3% to 3.0%); no seroconversions occurred after other routes of exposure. Blood-filled needlesticks and source patient coinfection with HIV appeared to be associated with a higher risk of seroconversion. Conclusions: The risk of HCV seroconversion after occupational exposure appears to be low but is not negligible. Aggressive implementation of universal precautions is important for preventing risk-prone exposure, but safer devices are also needed.

Occupational hepatitis C virus infection in Italian health care
workers. Italian Study Group on Occupational Risk of Bloodborne
Infections. American Journal of Public Health 1995;85:1272-5.
ABSTRACT: The risk of exposed health care workers in 16 Italian hospitals becoming infected with hepatitis C virus was assessed through two serosurveys at a 1-year interval and at followup. Prevalence, which was 2.2%, was significantly associated with previous acute hepatitis, blood transfusions, housekeeping, and older age (> 46 years) but not with occupational risk factors. After 1 year, 2622 (87%) of the 3006 seronegative health care workers were retested, and 3 (0.1%), who did not acknowledge occupational or community risk factors, seroconverted. Additionally, 133 (97 needlesticks) out of 370 reported occupational exposures were to hepatitis C virus; one pricked nurse seroconverted (0.75%). Although the risk is not negligible, hepatitis C virus infection does not seem to be easily occupationally transmitted.

immunodeficiency virus infection for emergency department workers.

Emergency Medicine 1994;12:737-44.
ABSTRACT: To evaluate the risk of human immunodeficiency virus (HIV) exposure among emergency department workers (EDWs) and their ability to identify HIV-infected patients, a seroprevalence study was performed in March 1991 in the emergency departments (EDs) of six Italian urban hospitals. At each visit, patients aged 18-65 years were asked to undergo fingerstick blood sampling for anonymous, unlinked HIV testing performed on blood adsorbed filter paper collection cards. Demographic characteristics, known or suspected HIV risk factors, and occupational exposures reported by the EDWs during the patient's visit were recorded. On 9,457 consecutive visits, 9,005 samples (95%) were tested and 65 (0.7%) were HIV positive. ED staff failed to identify 59% of HIV- infected patients. The rate of occupational exposures was 0.13/100 visits. As it is impossible to predict the HIV status of patients attending EDs, adherence to universal precautions and the development of safer devices should be utilized to minimize the risk of blood-borne infections in EDWs.

et al. Device-specific risk of needlestick injury in Italian health
care workers. Journal of the American Medical Association
ABSTRACT- Objectives: To identify the types of medical devices causing needlestick injuries among Italian health care workers, to document the device-specific injury rates and time trends for different hollow-bore needles, and to compare injury rates from these devices with those reported in the United States. Design: Longitudinal survey. Settings: Twelve Italian acute care public hospitals. Methods: Data were obtained from a multihospital surveillance database on the number of total injuries reported in each device category. Hospitals provided the corresponding number of devices used annually for each needle type. Main outcome measure: Number of needlestick injuries by type of hollow-bore needle per 100,000 devices used per year. Results: A total of 2524 injuries from hollow-bore needles were reported. Disposable syringes/hypodermic needles accounted for 59.3% of injuries, followed by winged steel needles (33.1%), intravenous catheter stylets (5.4%), and vacuum-tube phlebotomy needles (2.2%). Intravenous catheter stylets had the highest needlestick injury rate (15.7/100,000 devices used), and disposable syringes had the lowest needlestick injury rate (3.8/100,000). In contrast to the other devices, the injury rate from winged steel needles increased from 6.2 per 100,000 in 1990 to 13.9 per 100,000 in 1992. Conclusions: The device-specific needlestick injury rates in Italy are similar to those reported in the United States, suggesting similar exposure experience in two countries. However, in contrast to the United States, needleless intravenous access is standard practice in Italy and thus eliminates one potential risk to Italian health workers. Implementation of safer equipment, such as shielded or retracting needles, and continuing training programs are needed to further reduce the hazards that health care workers face.

ABSTRACT- Background: More than 50 cases of occupationally acquired human immunodeficiency virus (HIV) infection in health care workers (HCWs) have been reported worldwide. Determinants of injuries and of infection are important to investigate to design effective prevention programs. Methods: In Italy, 29 acute-care public hospitals were enrolled in a multicenter study between 1986 and 1990. At each facility, all HCWs were enrolled who reported percutaneous, mucous-membrane, or nonintact- skin exposure to the body fluids and tissues to which universal precautions apply from an HIV-infected patient. Data were collected at the time of the incident on clinical status of the HIV-infected source, circumstance and type of exposure, and use of infection control precautions. The HCWs were followed up clinically and serologically for HIV infection at 1, 3, 6, and 12 months. Results: A total of 1592 HIV exposures were reported in 1534 HCWs; most exposures (67%) occurred in nurses, followed by physicians and surgeons (17.5%). Needlesticks were the most common source of exposure (58.4%), followed by nonintact-skin and mucous-membrane contamination (22.7% and 11.2%, respectively) and cuts (7.7%). At the time of exposure, 77.5% of the HCWs knew or suspected that the source patient was HIV infected. Two seroconversions were observed among a total of 1488 HCWs followed up for at least 6 months: one occurred in a student nurse who had been stuck with a needle used for an HIV antibody-negative, p24 HIV antigen-positive drug addict; the other was in a nurse who experienced mucous-membrane contamination with a large quantity of blood from an HIV-positive hemophilic patient. The seroconversion rate was 0.10% after percutaneous exposure (1/1003; 95% confidence interval, 0.006% to 0.55%) and 0.63% after mucous-membrane contamination (1/158; 95% confidence interval, 0.018% to 3.47%). Conclusions: The study demonstrates a small but real risk of HIV infection after percutaneous and mucous-membrane exposure to blood of HIV infected patients and that transmission can occur during the "window period" of infection. Furthermore, exposures to HIV are not infrequent, and many exposures could be prevented with the use of barrier precautions, appropriate behaviors, and safer devices and techniques.

C, Franco E, Perucci CA, Rapiti E, Zullo G. Needlestick injury in
hospital personnel: a multicenter survey from central Italy. The Latium
Hepatitis B Prevention Group. Infection Control and Hospital
ABSTRACT- Objectives: To assess the rate of needlestick injury in hospital personnel in an Italian region. To identify risk factors potentially amendable to correction. Design: Hospital workers undergoing hepatitis B prevaccination testing in 1985 through 1986 were interviewed regarding needlestick injury in the previous year, job category, area of work, years of employment, and other pertinent information. Setting: Of the 98 public hospitals of the Latium region, 68 participated in the survey: 32 of 55 with less than 200 beds, 20 of 25 with 200 to 300 beds, 11 of 13 with 400 to 900 beds, and all of the 5 with more than 1,000 beds. Participants: All healthcare workers providing direct patient care or environmental services as well as student nurses were invited by the hospital directors to undergo hepatitis B prevaccination testing and vaccination, if eligible. Results: Of 30,226 hospital workers of the 68 participating hospitals, 20,055 were interviewed (66.3%): 47.7% of the 7,172 doctors, 71% of the 14,157 nurses, 55.9% of the 2,513 technicians, and 71.9% of the 6,384 ancillary workers. Needlestick injury was recalled by 29.3%; the rates were 54.9%, 35.3%, 33.8%, 26.5%, 18.7%, and 14.7% in surgeons, registered and unskilled nurses, physicians, ancillary workers, and technicians, respectively. The recalled injury rate was 39.7% and 34.0% in surgical and intensive care areas; in infectious diseases, it was 16.7%. Rates were lower in hospitals with 200 to 300 beds (25.6%). The needlestick injury rate declined from 32% in those with less than 5 years of employment to 28% in those with more than 20 years (p less than .01). Prevalence of HBV infection was higher in student nurses and young workers recalling a needlestick exposure (14.3% and 15.8%, respectively), versus 10.1% and 12.8% in those not exposed (p less than .01 and less than .05, respectively). Conclusions: Parenteral exposure to blood-borne infectious agents is a relevant risk among healthcare workers in our region, particularly in defined job categories and hospital areas (surgeons, nurses, surgical, and intensive care areas). Immunization and educational efforts should be made along with better designs of devices to reduce the risk of infection.

Ganczak M, Barss P. Nosocomial HIV infection: epidemiology and
prevention - A global perspective. AIDS Reviews 2008;10:47-61.
ABSTRACT- Because, globally, HIV is transmitted mainly by sexual practices and intravenous drug use and because of a long asymptomatic period, healthcare-associated HIV transmission receives little attention even though an estimated 5.4% of global HIV infections result from contaminated injections alone. It is an important personal issue for healthcare workers, especially those who work with unsafe equipment or have insufficient training. They may acquire HIV occupationally or find themselves before courts, facing severe penalties for causing HIV infections. Prevention of blood-borne nosocomial infections such as HIV differs from traditional infection control measures such as hand washing and isolation and requires a multidisciplinary approach. Since there has not been a review of healthcare-associated HIV contrasting circumstances in poor and rich regions of the world, the aim of this article is to review and compare the epidemiology of HIV in healthcare facilities in such settings, followed by a consideration of general approaches to prevention, specific countermeasures, and a synthesis of approaches used in infection control, injury prevention, and occupational safety. These actions concentrated on identifying research on specific modes of healthcare-associated HIV transmission and on methods of prevention. Searches included studies in English and Russian cited in PubMed and citations in Google Scholar in any language. MeSH keywords such as nosocomial, hospital-acquired, iatrogenic, healthcare associated, occupationally acquired infection and HIV were used together with mode of transmission, such as "HIV and hemodialysis". References of relevant articles were also reviewed. The evidence indicates that while occasional incidents of healthcare-related HIV infection in high-income countries continue to be reported, the situation in many low-income countries is alarming, with transmission ranging from frequent to endemic. Viral transmission in health facilities occurs by unexpected and unusual as well as more frequent modes. HIV can be transmitted to patients and to donors of blood products by specific vehicles and vectors during blood transfusion, plasma donation, and artificial insemination, by improperly sterilized sharps, by medical equipment during activities such as dialysis and organ transplantation, and by healthcare workers infected by occupational exposure to hazards such as blood-contaminated sharps. Personal, equipment, and environmental factors predispose to acquisition of nosocomial HIV and all are pertinent for prevention. For infection and injury control, poverty is often an underlying determinant. While sophisticated new tests offer improved HIV detection, increasingly higher marginal costs limit their feasibility in many settings. Modest investment in safer equipment and appropriate integrated training in infection control, injury prevention, and occupational safety should provide greater benefit.

[Article in Polish]Medycyna Pracy 2007;58:13-17.
ABSTRACT- Sharp injures continue to pose a significant risk for the transmission of blood-borne pathogens from the patient to health care workers. Appropriate use of safe devices can significantly reduce such risk. On the basic of a literature review, information is provided about active and passive safety features of medical equipment, and the crucial elements needed for the proper evaluation of a safe device are discussed. Examples of safety equipment are presented. Barriers to the use of these new products are addressed. The user-based system approach for the selection and implementation of safety devices is also described.
Ganczak M, Szych Z. Surgical nurses and compliance with personal
protective equipment. Journal of Hospital Infection
ABSTRACT- The study objectives were to evaluate self-reported compliance with personal protective equipment (PPE) use among surgical nurses and factors associated with both compliance and non-compliance. A total of 601 surgical nurses, from 18 randomly selected hospitals (seven urban and 11 rural) in the Pomeranian region of Poland, were surveyed using a confidential questionnaire. The survey indicated that compliance with PPE varied considerably. Compliance was high for glove use (83%), but much lower for protective eyewear (9%). Only 5% of respondents routinely used gloves, masks, protective eyewear and gowns when in contact with potentially infective material. Adherence to PPE use was highest in the municipal hospitals and in the operating rooms. Nurses who had a high or moderate level of fear of acquiring human immunodeficiency virus (HIV) at work were more likely (P < 0.005 and P < 0.04, respectively) than staff with no fear to be compliant. Significantly higher compliance was found among nurses with previous training in infection control or experience of caring for an HIV patient; the combined effect of training and experience exceeded that for either alone. The most commonly stated reasons for non-compliance were non-availability of PPE (37%), the conviction that the source patient was not infected (33%) and staff concern that following locally recommended practices actually interfered with providing good patient care (32%). We recommend wider implementation, evaluation and improvement of training in infection control, preferably combined with practical experience with HIV patients and easier access and improved comfort of PPE.

bloodborne viruses in Poland. Infection Control and Hospital
ABSTRACT- Study objective: To record descriptions of occupational exposures to blood, determine factors predictive of exposure, and identify interventions that might reduce the frequency of exposure. Design: An analytic, cross-sectional survey. Study population: A total of 601 nurses from surgical wards, operating rooms, and emergency departments. Study instrument: An anonymous questionnaire developed by the authors on the basis of previously published guidelines was distributed between January and March 2003. Sampling: Random, with 18 hospitals selected from 2 urban and rural locations. Results: Almost half of respondents reported having had at least 1 puncture injury during the preceding year, 1 in 5 had exposure via mucous membranes, and more than half had worked at least once with a recent abrasion or cut on their hands. The number of injuries was independent of age (P=.26), duration of practice (P=.21), and workplace setting (P=.78). The percentage of nurses without percutaneous exposure during the preceding year was significantly higher in the group that received special HIV/AIDS training than in the group that did not (95% confidence interval, 5.8-24.1%; P<.002). The most recent exposure was primarily caused by hollow-bore needles, involved the palm and fingers II-V, was self-inflicted, took place during an elective procedure, and was not reported to the hospital's infection control center by 74% of respondents. The most common reason for not reporting the exposure (38% of cases) was the conviction that the source patient was not infected. Conclusions: Because of the large number of occupational exposures to blood, especially those due to injuries with hollow-bore needles, nurses should adopt more adequate behavioral strategies to prevent the transmission of blood-borne pathogens. Policies for providing adequate education programs tailored to encourage nurses to report all exposures are urgently required.
Bilski B. Needlestick injuries in nurses--the Poznan study.
International Journal of Occupational Medicine & Environmental
ABSTRACT- Objectives: Needlestick injuries in healthcare workers are common. They are one of the main ways of transmitting large numbers of pathogenic micro-organisms in healthcare institutions. The aim of this study was to estimate the incidence and circumstances of needlestick injuries in a selected population of nurses from the city of Poznan and the Wielkopolskie province. Materials and methods: A questionnaire was filled in by 232 active nurses with secondary education, studying externally at the Medical University in Poznan. The sample was representative of nursing specialisations and workplaces of nurses in Poznan and the Wielkopolskie province. It comprised of nurses aged 22-51 years (mean, 35 years) and with work experience of 2-31 years (mean, 13 years). The workplaces of the study group were fairly diverse, but the great majority of nurses were employed in inpatient care, working in shifts (166 people). Results: The probability of needlestick injuries per year equals 28.0%. Accidents of this kind were most common among nurses working in surgical wards, operating rooms, emergency medical care, GP surgeries and dialysis units. There were significant differences in the incidence of needlestick injuries between GP surgeries (statistically more common) on the one hand, and surgical wards, non-surgical wards and operating rooms on the other. Moreover, accidents in operating rooms and surgical wards were significantly more common compared to non-surgical wards. Instruments contaminated with infectious material accounted for 73.8% of the injuries in the study group of nurses. They were usually injection needles. Injuries from sterile needles, clean scalpels and contaminated scalpels were much less common. In the vast majority of cases, injuries were self-inflicted, and much less frequently caused by patients or colleagues. Most of these accidents happened during an attempt to remove a needle from a syringe, and much less while trying to place a used needle in a full medical waste container. In almost half of the cases (44.9%), the accidents occurred between the second and the fourth hour of the shift, which was probably due to a typically heavy workload during those hours, particularly on a morning shift. In the great majority of cases (84%), the nurses were wearing protective gloves at the time of accidents. Conclusions: The probability of a needlestick injury in the study group per year was 28.0%. Accidents of this kind were most common in nurses working in dialysis units, emergency medical care, GP surgeries, surgical wards, and operating rooms. Occupational sharps injuries were most often caused by a contaminated injection. The injuries were self-inflicted in the vast majority of cases. The most common cause of injuries from needles was an improper handling of syringes and needles after injections (removing a needle from a syringe or placing the needle in a full container for medical waste).
Chlabicz S. [The healthcare worker as a source of hepatitis C virus
infection][Polish] Polski Merkuriusz Lekarski 2005;19:225-8.
ABSTRACT- The paper discusses risks associated with the possibility of transmission of hepatitis C virus (HCV) infection from an infected healthcare worker to a patient. Reports describing infections where a healthcare worker was the source of HCV infection to patients are summarized and guidelines concerning approach to infected healthcare workers in other countries are presented. Surgeons performing exposure-prone procedures are almost the only source of infection to patients, provided that universal precautions are respected. Exposure prone procedures occur most commonly during gynaecologic, orthopedic, thoracic operations. At present routine testing of all healthcare workers for HCV infection is not justified. Some experts recommend screening for HCV infection surgeons performing exposure-prone-procedures. Although the present risk of HCV transmission from a HCV infected (HCV-RNA positive) healthcare worker to a patient is small, estimated to be about 1/7000 surgical procedures, some countries recommend that healthcare workers infected with HCV should be restricted from undertaking exposure prone procedures.

ABSTRACT- Patients can be infected with hepatitis B or C or HIV as a result of exposure to blood of infected health professionals, especially surgeons. This article reviews the literatureon single and multiple cases of such infections. Risk factors for exposure and for infection are summarised. The probability of infection after a single exposure is reviewed. Standard recommendations for prevention on infection from health controversy and this also considered. Experts and regulatory bodies in Poland need to take decisions and prepare written policies on how best to prevent transfer of blood borne viruses from health care workers to patients.
Hutin YJ, Harpaz R, Drobeniuc J et al. Injections given in
healthcare settings as a major source of acute hepatitis B in Moldova.
International Journal of Epidemiology 1999;28:782-6.
ABSTRACT: Background: Reported rates of acute hepatitis B are high in many former Soviet Union republics and modes of transmission are not well defined. Methods: Two case control studies were undertaken in Moldova to identify risk factors for acute hepatitis B in people aged 2-15 years (children) and > or =15 years (adults). Serologically confirmed acute hepatitis B cases occurring between 1 January 1994 and 30 August 30 1995, were matched on age, sex, and district of residence to three potential controls who were tested for hepatitis B markers to exclude the immune. Stratified odds ratios (SOR) were calculated using bivariate and multivariate methods. Results: In multivariate analysis, compared with the 175 controls, the 70 adult cases (mean age 25 years, 66% male) were more likely to report receiving injections in the 6 months before illness during a dental visit (SOR = 21; 95% CI: 3.7-120), a hospital visit (SOR = 35; 95% CI: 7.2-170), or a visit to the polyclinic (SOR = 13; 95% CI: 2.4-74). Among children, receiving injections during a hospital visit (SOR = 5.2; 95% CI: 1.2-23) was the only exposure reported significantly more often by the 19 cases (mean age 8 years, 68% male) compared with the 81 controls. Conclusion: These results, along with reported unsafe injection practices in Moldova, suggest that injections are a major source of hepatitis B virus transmission and highlight the importance of proper infection-control procedures in preventing transmission of blood-borne infections.

ABSTRACT- Markers of hepatitis B (HBsAg, anti-HBs) and C (anti-HCV) were detected in 1990-1992 by enzyme immunoassay in 1581 medical workers, 230 last-year students of medical schools, 269 patients hospitalized at hemoperfusion wards, and 701 blood donors. Hepatitis B markers were detected in medical workers two times more frequently than in donors (HBsAg in 4.7 and 2.2% of these, respectively, anti-HBs in 26.2 and 14.0%), and anti-HCV were found almost three times more frequently (in 3.1 and 1.1%, respectively). The incidence of these markers in students of medical schools was the same as in donors. Hepatitis B markers (HBsAg, anti-HBs) were detected in 39.0% of patients of hemoperfusion departments, HBsAg being present in 11.9%, and antiHCV in 25%. A direct relationship was revealed between the incidence of hepatitis B and C markers and duration of treatment at dialysis centers or length of service at therapeutic institutions. Three vaccinations with Engerix B 944 vaccine were administered to 944 medical workers and 162 medical students and four vaccinations in double doses to 40 patients of hemoperfusion centers who had no hepatitis B markers; a month after immunization anti-HBs in protective titers were detected in 91.4, 93.9, and 76.1% of them, respectively, and a year after vaccination these values were 77.2, 82.5, and 53.3%. No cases of hepatitis B, detection of HBsAg, or postvaccination complications in the vaccines were recorded.

perception and attitudes towards HIV in Serbian health care workers.
Occup Med (Lond) 2006;56(4):275-8.
ABSTRACT - BACKGROUND: Health care workers (HCWs) are at risk of occupational exposure to human immunodeficiency virus (HIV). AIM: To investigate the perception of professional risk from, and the knowledge, attitudes and practice of HCWs to HIV and AIDS in Serbia. METHODS: Cross-sectional study of 1,559 Serbian HCWs using self-administered anonymous questionnaires. Chi-square testing and multiple logistic regression analysis were applied. RESULTS: Eighty-nine per cent of HCWs believed that they were at risk of acquiring HIV through occupational exposure. The perception of professional risk was higher among HCWs frequently exposed to patients' blood and body fluids (OR 7.9, 95% CI 4.4-14.5), who used additional personal protection if the HIV status of patient was known (OR 2.6, 95% CI 1.5-4.6), who had experienced sharp injuries within the last year (OR 1.9, 95% CI 1.0-3.8) or who had been tested for HIV (OR 2.1, 95% CI 1.2-3.5), and among HCWs who had treated HIV-positive patients (OR 1.7, 95% CI 1.1-2.8). The majority of respondents had deficient knowledge about modes of HIV transmission. Attitudes towards HIV-positive patients were significantly different by occupation. Seventy per cent of HCWs used appropriate protection during their daily work with patients. CONCLUSIONS: HCWs require specific educational programmes and training protocols to ensure that they are adequately protected when carrying out high quality care.

professional exposure to blood and blood-containing materials in
serbian health care workers. J Occ Health 2006;48:377-82.
ABSTRACT: Safety practice is an important element of workplace safety and quality of health care. To investigate the safety practice and professional exposure to blood and bloodcontaining materials during a one-year period among Health Care Workers (HCWs) in Serbia. Cross-sectional study of 1559 Serbian HCWs using a self-administered questionnaire. Mantel-Haenszel statistics and multiple logistic regression analysis were used in statistical analysis. Fifty-nine percent (921) of HCWs had skin contact with patients blood, followed by 51% (791) with needle stick injuries, 38% (599) with cuts from sharp instruments, and 34% with contact of eye and other mucosa with patient's blood. Nurses reported professional exposure more often than others. Safety practices consisted of using appropriate barriers (gloves, mask, glasses) in all procedures with patients and were used by 58%, 23%, and 4% of HCWs, respectively. Doctors protected themselves more regularly than others. Hospital protocols for post exposure prophylaxis and safety disposal of medical waste are not common in Serbian health care settings. Safety practices in use were having hospital guidelines for safety practice in hospitals [odds ratio (OR)=1.58, 95% confidence interval (CI)=1.14-2.19], carrying out some form of intervention with risks of infection (OR=3.76, 95% CI=2.57-5.51), and HCWs aware of the professional risk of acquiring infection (OR=1.48, 95% CI=1.28-1.79). This study indicates that emphasis on work practice, attire, disposal systems and education strategies, should be employed to reduce.

Occupational exposure to human immunodeficiency virus in hospital
health care workers in Spain. Vacunas [Vaccines] 2007
ABSTRACT: Human immunodeficiency virus (HIV) is an occupational risk in health workers exposed to HIV-positive blood. In the present study prospective surveillance of all cases of occupational exposure to HIV among health workers in a large Spanish hospital was performed over a 4-year period. In the present study prospective surveillance of all cases of occupational exposure to HIV among health workers in a large Spanish hospital was performed over a 4-year period. Methods. Methods. We performed a prospective epidemiological study of all cases of occupational exposure to HIV infection from July 1998 to June 2002. We performed a prospective epidemiological study of all cases of occupational exposure to HIV infection from July 1998 to June 2002. Details on the source patient and exposed health worker, as well as place and time of exposure, were gathered.

ABSTRACT- Objective: To study the effectiveness of safety devices intended to prevent percutaneous injuries.Design. Quasi-experimental trial with before-and-after intervention evaluation. Setting: A 350-bed general hospital that has had an ongoing educational program for the prevention of percutaneous injuries since January 2002. Methods: In October 2005, we implemented a program for the use of engineered devices to prevent percutaneous injury in the emergency department and half of the hospital wards during the following procedures: intravascular catheterization, vacuum phlebotomy, blood-gas sampling, finger-stick blood sampling, and intramuscular and subcutaneous injections. The nurses in the wards that participated in the intervention received a 3-hour course on occupationally acquired bloodborne infections, and they had a 2-hour "hands-on" training session with the devices. We studied the percutaneous injury rate and the direct cost during the preintervention period (October 2004 through March 2005) and the intervention period (October 2005 through March 2006). Results: We observed a 93% reduction in the relative risk of percutaneous injuries in areas where safety devices were used (14 vs 1 percutaneous injury). Specifically, rates decreased from 18.3 injuries (95% confidence interval [CI], 5.9-43.2 injuries) to 0 injuries per 100,000 patients in the emergency department (P=.002) and from 44.0 injuries (95% CI, 20.1-83.6 injuries) to 5.2 injuries (95% CI, 0.1-28.8 injuries) per 100,000 patient-days in hospital wards (P=.007). In the control wards of the hospital (i.e., those where the intervention was not implemented), rates remained stable. The direct cost increase was euro0.558 (US$0.753) per patient in the emergency department and euro0.636 (US$0.858) per patient-day in the hospital wards. Conclusion: Proper use of engineered devices to prevent percutaneous injury is a highly effective measure to prevent these injuries among healthcare workers. However, education and training are the keys to achieving the greatest preventative effect.

exposure to biological material contaminated with HIV in workers at a
third level hospital in Madrid]. [Spanish] Revista espanola de salud
ABSTRACT - Background: Human Immunodeficiency Virus (HIV) is an occupational hazard among healthcare professionals accidentally contaminated with HIV-positive blood. This study is aimed at describing the characteristics of the accidents involving blood of HIV-positive patients recorded over a sixteen-year period at a general hospital. Methods: Epidemiological study of the accidents reported in 2001 involving biological material from an HIV-positive source by the healthcare personnel of a general hospital throughout the 1986-2001 period entailing the presence of biological material from HIV-positive serology individuals. Individual, time and place-related variables, in addition to the initial serologies and those throughout the protocolized follow-up were studied for those individuals involved in these accidents. RESULTS: A total 550 accidents entailing an HIV-positive source were reported. The average number of accidents was 34.4/year. The accidental exposure rate for the period under study was 7.5/1000 workers/year. The professional group showing the highest accident rate was the nursing staff (54.4%). Percutaneous injuries were the most frequent (80.2%). The mean exposure rate was 2.6/100 beds/year. The anatomical areas involved to the greatest degree were the fingers (75.6%). A total 53.4% of those injured completed the serological follow-up without having shown any seroconversion. CONCLUSIONS: Throughout the sixteen-year period under study, the annual incidence of accidents involving an HIV-positive source increased from the 27 accidents reported in 1986 to the 60 accidents reported in 1990, there having been a downward trend as of that point in time, to the point of 12 accidents having been recorded in 2001.

ABSTRACT- Background and objective: The bloodborne injury is the most frequent risk in healthcare workers. Among them, the hollow-bore needlesticks are the most associated with the risk of acquire a bloodborne infection. In this study, occupational percutaneous injuries and risk factors associated to hollow-bore needlesticks registered in a national multicenter surveillance system are described. Patients and method: Prospective and analytical study of percutaneous injuries registered in the surveillance system EPINETAC (Exposure Prevention Information Network) in Spain between 1996-200. A descriptive analysis of the variables related to the exposed healthcare worker, the exposure and their mechanism and the source patient is performed. The incidence rates were calculated by 100 occupied beds and by job category. A multivariable analysis is performed in order to know the risk factors most associated to hollow-bore needle. Results: 16,374 percutaneous injuries has been registered, which 87% are hollow-bore needlesticks. The incidence rate has been 11.8 expositions per 100 occupied beds. Midwives are the most risky workers (9 injuries per 100 occupied beds). The risk factors most associated to hollow-bore needlesticks are the following: job category of midwife (OR = 7.5 95% CI, 4.1-13.7) and student nurse (OR = 2.1; 95% CI, 1.2-3.7), recapping (OR = 28.8; 95% CI, 16.5-50.6), working in venipuncture room (OR = 3.3; 95% CI, 1.2-9.5) or in the dialysis unit (OR = 2.5; 95% CI, 1.4-4.3). Conclusions: The incidence of occupational percutaneous injuries in Spain is similar to those described in other countries using comparable surveillance systems. The risk of hollow-bore needlestick is directly related to job category, work experience, work area and the activities that the healthcare worker does.

workers] [in Spanish] Enferm Infecc Microbiol Clin. 2001
ABSTRACT - Objective: To determine the rate of occupational exposures to blood-borne pathogens in different occupations of health care workers. To analyze the characteristics and outcome of the occupational exposure. Material and methods: We have evaluate occupational exposures to blood-borne pathogens reported by health care workers during 1996-1999. The following data were collected: characteristics of the workers, type of occupational exposure, immunity status of the exposed worker, infectivity of the source patient and follow up serologic testing of the worker. Results: A total of 407 occupational exposures were reported. The highest rate of occupational exposure was found among nurses (61.6%). Needlestick accident was the most often occupational exposure reported (84.5%). Mucosal exposures with accidental splashes were reported in 15.2% of cases. In 14.5% of these accidents workers were at risk for occupational transmission of blood-borne pathogens. Among the different occupations of health care workers, the rate of exposures with a source infected patient was higher in medical staffs (28.3%) than nurses (13.9%) The rate of exposures with a source infected patient was higher in accidental splashes than in percutaneous exposures (33.8% vs 13.3%), besides in none of the accidental splashes, employees had used appropriate barrier precautions. There were no cases of transmission of occupational blood-borne infections. Conclusions: Although nurses are the health care workers with highest rates of occupational exposures, medical staffs are the most often occupationally exposed to a source infected patient. Universal barrier precautions are no appropriately used in most of the occupational accidents, specially in those involving mucosal exposures.

Group). Epidemiology of biological-exposure incidents among Spanish
healthcare workers. Infection Control and Hospital Epidemiology
ABSTRACT- Objective: To determine the frequency and the epidemiological characteristics of biological-exposure incidents occurring among healthcare personnel. Design: Prospective surveillance study. Setting: Participating Spanish primary-care and specialty centers from January 1994 to December 1997. Participants: 70 centers in 1994, 87 in 1995, 97 in 1996, and 104 in 1997. Methods: Absolute and relative frequencies were calculated for several variables (position held, area of care, type of injuring object, activity, etc) and for the different categories of each variable. Results: There were 20,235 registered incidents. Annual incidence rates were as follows: 1994, 51 per 1,000; 1995, 58 per 1,000; 1996, 54 per 1,000; and 1997, 59 per 1,000. Mean age of accident victims was as follows: 1994, 35.68 (standard deviation [SD], 16.26); 1995, 33.6 (SD, 11.9); 1996, 38.2 (SD, 17.27); and 1997, 36.7 (SD, 16.33) years. Of the 20,235 incidents, 15,860 (80.7%) occurred to women; 50% (9,833) accidents were among nursing staff. The type of incident most frequently reported was percutaneous injury (81.1%). The highest frequency of accidents was seen in medical and surgical areas (28% and 25.6%, respectively). Blood and blood products were the most commonly involved material (87.6%). Administration of intramuscular or intravenous medication was the activity associated with the highest accident rate (20.3%). The most frequent immediate action in response was rinsing and disinfecting (65.6%). Conclusions: The incident registry was highly stable in terms of incidence rates over the observation period and served to highlight the large number of incidents recorded each year. The potential implications of the results are the need to explore reasons for increased exposures in certain areas, with the aim of focusing prevention efforts, and, similarly, to establish the factors associated with diminished incidence rates to model successful measures.

accidents in a teaching hospital in Spain. Clinical Performance and
Quality Health Care 1999;7:88-91.
ABSTRACT- The study's objectives were to determine the frequency of biological-risk accidents involving percutaneous exposure and to identify factors associated with underreporting. Two hundred fifty healthcare professionals from inpatient services at high risk for exposure at the Puerta del Mar University Hospital of Cádiz, Spain, participated in the study. A questionnaire was used to measure personal and work variables, the number of accidents suffered and reported in the last year, and the circumstances motivating the reporting or nonreporting. Two hundred thirty-two persons (92.8%) completed the questionnaire. The accident rate was 12 per 100,000 hours worked. Physicians were the most frequent accident victims (rate 22/100,000 hours). The general surgery and emergency services had higher rates than other services (rates 19.82 and 14.17, respectively). Sixty-six percent of the accidents were not reported to the register. The main predictors of the underreporting were length of professional service greater than 19 years, working in the surgery service, and the perception that the accidents did not involve health risk. The true accident rate was higher than that reflected in the Accident Register. Underreporting was high. The main variables associated with underreporting were length of professional service, work area or department, and perception of risk from the accident.

infection after accidental exposure. Medicina Clinica
ABSTRACT- Background: The objective of the study was to quantify the risk of infection by hepatitis C virus (HCV) in health care workers (HCWs) after accidental exposure. Subjects and methods: The study was carried out in Catalonia (Spain) and included data from 22 hospitals. All reported cases of accidental exposure to blood or other biological fluids contaminated by HCV were included, which occurred between January 1993 and June 1995 to HCW with a negative HCV serology at the time of exposure, and with a follow-up of at least six months. Results: The hospitals reported a mean of 1.7 exposures per 100 beds per year. Ninety one percent of exposures were needlestick injuries or cuts. Three cases of HCV seroconversion were detected among a total of 443 exposures, with a risk of seroconversion of 0.7% (95% confidence interval [C]: 0.14-1.9%). Details of clinical and serological data of infected HCWs are included. In all of them the source patient was coinfected with HIV. Overall, in 106 (25.2%) exposures the patient source was infected by HCV and HIV, with a risk of seroconversion associated with coinfected of 2.8% (95% Cl:0.59-8.05%). None of the HCWs exposed only to HCV seroconverted. Conclusions: The risk of HCV infection after accidental exposure to infected biological material is below 1%. This risk significantly increases for simultaneous exposures to HCV and HIV.

associated with accidents caused by percutaneous exposure in nursing
staff at a tertiary level hospital [in Spanish]. Revista española de
salud pública 1997;71:369-81.
ABSTRACT- Background: Accidents resulting from percutaneous exposure account for approximately one third of all accidents suffered at work by health workers in hospitals. Their importance lies in the illnesses caused by pathogens that can be transmitted in this way (hepatitis B, hepatitis C, HIV virus). The aims are to describe accidents of this type notified in a tertiary level hospital, identify factors associated with these accidents in nursing staff and build a predictive model for the individual risk of having an accident. Methods: A descriptive study of a retrospective cohort made up of all the people who notified having suffered an accident between 1-1-93 and 30-6-96. A study of cases and controls in nursing staff during the period 1-1-95 to 30-6-96, analysed through multiple logistical regression. Results: The cumulative incidence of cases of accidents in one year was 0.078 for male and female nurses. In 57.3% of cases, disposable or pre-loaded syringes were involved. The cumulative incidence of cases in one year was greater for intravenous catheterisation (8.5% per 100,000). The risk of having an accident, adjusted on account of confusing variables, was greater for female and male nurses (OR = 3.22; I.C.95% = 1.96-5.27), or workers in the Haemodialysis Unit (OR = 35.21; I.C.95% = 3.74-331.16) and for those employed on a temporary contract (OR = 4.50; I.C.95% = 2.24-9.04). Conclusions: Accidents resulting from percutaneous exposure at this hospital are more frequent among nursing staff and are basically caused by any type of hollow needles. Factors associated with these accidents were identified, allowing specific prevention programmes to be targeted at those workers at greater risk. The model obtained is valid to estimate the degree of individual accident probability for the subjects studied.

transmission of HIV infection among health care workers. European

ABSTRACT- The aim of this study was to evaluate the HIV seroconversion rate associated with different types of occupational exposures in health care workers. A longitudinal study was conducted from January 1986 to October 1992 in a teaching hospital in Spain, where HIV infection is prevalent among patients. Each health care worker was asked to complete a questionnaire regarding age, sex, staff category, lace of exposure, other exposures, type of exposure, body fluid, infected material and HIV status of source patient. These health care workers were then followed up at 6 weeks, 3 months, 6 months and 12 months with repeated test for HIV antibody. Four hundred twenty three reports of occupational exposure were analysed. Nursing was the profession with more exposures (42.8%). Ninety five percent of total exposures were percutaneous, 4% mucous membrane contacts and 1% skin contacts, 88.3% were described as blood contact and 71.8% had resulted from needlestick and suture needles. Exposures from HIV-positive patients comprised 23.2% of occupational exposures. There was a significant difference in the length of follow-up in physicians (p=0.00009) and nurses (p=0.00001), when we compared HIV-positive patients with patients in whom the HIV status was unknown or negative. The HIV seroconversion rate was 0.00%. We consider that the risk of acquiring HIV infection via contact with a patient is low, but not zero. Well documented cases of seroconversion have been published. Because it is often impossible to know a patient's infection status, health care workers should follow for rotine the universal precautions for all patients when there is a possibility of exposure to blood or other body fluid. Equally important is the development of new techniques to minimize the risk of exposures to blood.

the Swedish health care setting and potential cost savings from
needle-stick prevention devices with needle and syringe. Scand J Infect
Dis 2009 Feb 19:1-7. [Epub ahead of print]
ABSTRACT: The number and costs associated with reported sharps injuries in Swedish hospitals and the potential cost offset by introducing safety devices with needle and syringe was estimated from a health care perspective. Data about reported sharps injuries were collected from infection control nurses at 18 Swedish hospitals and information about the procedures following such injuries from doctors at Swedish hospitals and published articles. Unit costs were derived from the Southern Regional Health Care Board, SEK 2007. On average, 3.14 injuries per 100 full-time equivalent positions are reported annually in Swedish health care. Approximately 60% involves hollow-bore needles. The cost of occupational sharps injuries in Sweden was estimated at euro1.8 million (SEK 16.3 million) or euro272 (SEK 2513) per reported injury, of which euro1 million was for hollow-bore sharps injuries. The expected number of injuries that could be avoided by introducing safety devices was estimated at 3125 injuries and the corresponding expected cost offset at euro850,000. Most costs are associated with investigation as opposed to treatment. The cost per reported injury in Sweden seems to be lower than in other EU countries and the US, due to more thorough investigation and treatment procedures in countries with confirmed transmission of pathogens to healthcare workers.

exposure incidents among healthcare workers in a university hospital in
Sweden. Journal of Hospital Infection 1997;35:223-35.
ABSTRACT- In an attempt to document blood exposure incidents and compliance with recommended serological investigations, universal precautions and incident reporting routines, data was collected from occupational injury reports during a two-year period. In addition, a sample of healthcare workers (HCWs) answered a questionnaire about blood tests and work routines. In a third part of the study some HCWs were asked about the type and actual frequency of incidents, together with the number of reported incidents during the two-year study period. Of a total of 473 reported occupational blood exposures, the majority came from nurses and the minority from physicians. Most reported incidents occurred on hospital wards. The most common incidents were needlestick injuries, and 35% occurred when the needle was recapped. Medical laboratory technicians (MLT) reported significantly more mucocutaneous incidents than other professionals (P < 0.01). In 10% of the incidents, the patient had a known blood-borne infection. Serological investigations post-exposure varied among professional groups, and 35% were not tested. No seroconversion was shown in the HCWs tested. In the third part of the study, respondents recalled 1180 incidents, although only 9% of these had been reported. The majority occurred in operating theatres, and in connection with anaesthesia. There was a significant difference (P < 0.001) between the different professional groups with regard to the frequency of incident reporting. Physicians reported only 3% and MLTs 36% of the incidents. Eighty-one percent believed that the accident could have been avoided. Despite knowledge of universal precautions, professionals continue to behave in a risky manner, which can result in blood exposure incidents.

the risk of surgical site infection. Arch Surg. 2009 Jun;144(6):553-8;
ABSTRACT: Clinically apparent surgical glove perforation increases the risk of surgical site infection (SSI). DESIGN: Prospective observational cohort study. SETTING: University Hospital Basel, with an average of 28,000 surgical interventions per year. PARTICIPANTS: Consecutive series of 4147 surgical procedures performed in the Visceral Surgery, Vascular Surgery, and Traumatology divisions of the Department of General Surgery. MAIN OUTCOME MEASURES: The outcome of interest was SSI occurrence as assessed pursuant to the Centers of Disease Control and Prevention standards. The primary predictor variable was compromised asepsis due to glove perforation. RESULTS: The overall SSI rate was 4.5% (188 of 4147 procedures). Univariate logistic regression analysis showed a higher likelihood of SSI in procedures in which gloves were perforated compared with interventions with maintained asepsis (odds ratio [OR], 2.0; 95% confidence interval [CI], 1.4-2.8; P < .001). However, multivariate logistic regression analyses showed that the increase in SSI risk with perforated gloves was different for procedures with vs those without surgical antimicrobial prophylaxis (test for effect modification, P = .005). Without antimicrobial prophylaxis, glove perforation entailed significantly higher odds of SSI compared with the reference group with no breach of asepsis (adjusted OR, 4.2; 95% CI, 1.7-10.8; P = .003). On the contrary, when surgical antimicrobial prophylaxis was applied, the likelihood of SSI was not significantly higher for operations in which gloves were punctured (adjusted OR, 1.3; 95% CI, 0.9-1.9; P = .26). CONCLUSION: Without surgical antimicrobial prophylaxis, glove perforation increases the risk of SSI.

Francioli P. The occurrence of percutaneous injuries to health care
workers: a cross sectional survey in seven Swiss hospitals.
Schweizerische Medizinische Wochenschrift 1998;128:536-43.
ABSTRACT- Objectives: In 1995, a cross sectional survey was conducted in 7 Swiss hospitals to estimate the incidence of percutaneous injuries among nurses, surgeons, anesthetists and domestic personnel, and to describe the circumstances of these injuries and the reporting process within the hospital. Methods: An anonymous questionnaire was distributed and filled out on-site in the case of nursing staff and domestic personnel, and was sent by post to physicians (anesthetists and surgeons). Participants were asked to report in detail on percutaneous injuries of the last workday and the last working month (nurses and physicians), and of the last month and the last year for domestic personnel. The overall response rate was 72%, representing a total of 3116 health care workers. Results: The annual incidence rates of percutaneous injury with material contaminated with blood or other biological fluids were calculated by type of worker for the two available units of time. For nurses, the incidence was 0.49 and 2.23, for surgeons 4.28 and 11.05, for anesthetists 2.11 and 3.14, and for domestic personnel 0.11 and 0.17 respectively. Most of the injuries occurred in a "normal" situation (no emergency, no stress, no fatigue) and were described as avoidable. Compliance with universal precautions was not optimal and declaration rates within the hospital rather low (nurses 39.7%, physicians 3.4%, domestic personnel 87.9%). Conclusions:Percutaneous injuries with blood-contaminated material are frequent in health care workers, and are not always adequately assessed because of under-reporting of accidents within the hospital. This may result in underestimation of current occupational exposure of health care workers to HIV and other blood-borne viruses.
Meyer-Wyss B, Erdin D, Prisender S, Stalder GA. Needlestick injuries
in hospital personnel and the risk of hepatitis-B infection [in
German]. Schweizerische Medizinische Wochenschrift
ABSTRACT- The risk of employees of the University Hospital of Basel acquiring virus hepatitis B following needle stick injuries (NSI) was evaluated prospectively. Over four years, 555 NSI were reported, resulting in a mean incidence of 48 NSI/1000 persons working/year. Of the injured, 455 (82%) had previously been vaccinated against hepatitis B, 32 (6%) were HBsAg and/or anti-HBc positive, and only 65 (12%) were at risk for HBV infection. The origin of 365 (66%) of the needles implicated in the NSI was identified, and of these 15 (4%) had been contaminated with HBsAg-positive blood. None of the 555 persons with NSI developed hepatitis. We conclude that the risk of HBV infection following NSI is low at our institution, but general measures need to be enforced to reduce the incidence of NSI in view of the potential risk that other infectious diseases may be transmitted by NSI.

Three-Year Prospective Study to Improve the Management of
Blood-Exposure Incidents. Infect Control Hosp Epidemiol 2008 Aug 25.
[Epub ahead of print]
ABSTRACT - Objective: Throughout 2003-2005, all blood-exposure incidents registered by an expert counseling center in The Netherlands accessible by telephone 24 hours a day, 7 days a week, were analyzed to assess quality improvement in the center's management of such incidents. The expert center was established to handle blood-exposure incidents that occur both inside and outside of a hospital. Infection control practitioners carried out risk assessment, made the practical arrangements associated with managing incidents, and carried out treatment and follow-up, all in accordance with standardized procedures. Design: We analyzed the time it took for exposed individuals to report the incident, the time required to perform a human immunodeficiency virus (HIV) test for the source individual when needed, occurrence of injuries, hepatitis B (HBV) vaccination status of exposed individuals, and adherence to protocol at the expert center. Results: A mean of 465 incidents was registered during each year of the 3-year study period. Although 698 (50%) of 1,394 reported exposures took place in a hospital, 704 (50%) took place outside of a hospital, and 460 (33%) occurred at a time other than regular office hours. HIV tests for source individuals were performed increasingly quickly over the course of the 3-year study period because of earlier reporting and improvements in practical matters associated with performing and processing the tests. The percentage of healthcare workers employed outside a hospital who were vaccinated against HBV increased from 34% (52 of 152) to 70% (119 of 170) during the 3-year study period. Consequently, the administration of immunoglobulin and unnecessary laboratory testing were reduced. In assessing the quality of the expert center, flaws in the handling of incidents were identified in 148 (37%) of 396 incidents analyzed in 2003, compared with 38 (8%) of 461 incidents analyzed in 2005. Conclusions: The practical matters associated with management of blood-exposure incidents, such as timely reporting and administration of prophylaxis, should be optimized for incidents that occur at times other than regular office hours and outside of hospitals. The establishment of a 24-hour centralized counseling facility that was open 7 days a week to manage blood exposures resulted in significant improvements in incident management and better care.

Effectiveness of protocols for preventing occupational exposure to
blood and body fluids in Dutch hospitals. J Hosp Infect
SUMMARY: Compliance of different healthcare workers (HCWs) (nurses, physicians, laboratory technicians and cleaners) with protocols to prevent exposure to blood and body fluids (BBF) was studied. Questionnaires were used to assess perception of risks, familiarity with protocols, motivation and actual behaviour. Performance of the protocols in practice was also tested. The practical test provided more reliable results than the questionnaire. HCWs overestimated their knowledge and skills, and compliance was influenced by risk perception. HCWs encountered problems with comprehension, acceptability and applicability of protocols, especially for post-exposure precautions. Protocols are not tailored to the differences in knowledge, risk perception and practical needs of different professional groups, probably because HCWs have rarely been involved in writing them and they are governed more by legal considerations than applicability. Most HCWs experienced a lack of organizational support to aid compliance. To improve compliance, we recommend information and training on risk management and individual responsibilities regarding the safety of coworkers and patients, participation of HCWs in protocol development, and support of management to avoid reversion to previous habitual behaviour.

exposure to blood : The need for improving the hepatitis B vaccination
grade among health care workers outside the hospital. Am J Infect
ABSTRACT: To describe the characteristics of needlestick injuries occurring to health care workers outside the hospital, a new case report form was implemented and analyzed after 12 months. A total of 144 incidents were reported. Of the needlestick injuries in nursing assistants, 84% involved an insulin needle or pen. Thirty-five percent of all health care workers and 47% of the nursing assistants were not vaccinated against hepatitis B. Hepatitis B vaccination grade in health care workers outside the hospital should be improved, in particular among nursing assistants.

Am J Prev Med 2005;28(2):169-74.ABSTRACT - OBJECTIVES: To assess and evaluate the rate and outcome of occupational exposure to hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) in the Amsterdam police force. METHODS: Retrospectively, all accidents with risk for viral transmission reported to the Municipal Health Service between January 1, 2000 and December 31, 2003 were described and analyzed in 2004. RESULTS: Over a 4-year period, 112 exposures with a viral transmission risk were reported (the estimated exposure rate was 68/10,000/year). Of these exposures, 89 (79%) sources were tested, finding 4% HBV-positive, 4% HIV-positive, and 18% HCV-positive. Immunoglobulin for HBV infection was given 44 times; HIV post-exposure prophylaxis was prescribed 16 times and 13 of 16 discontinued the course within a few days because the transmission source tested HIV-negative. No seroconversions were seen in persons exposed. CONCLUSIONS: The rate of exposure is low. The majority of the sources could be traced and tested. However, a comprehensive and effective protocol is essential in minimizing the risk of occupational HBV, HCV, and HIV infection in police officers, even if HBV vaccination is provided.

Beld MG. A physician with a positive hepatitis C virus RNA test after a
needlestick injury. Eur J Gastroenterol Hepatol 2003; 15:1367-9.
ABSTRACT: Needlestick accidents continue to be a hazard for healthcare workers. We report the development of acute hepatitis C infection in a physician after needlestick injury. Hepatitis C virus (HCV)-RNA, seroconversion and a raised plasma alanine aminotransferase (ALAT) level were found in plasma three months after the accident. Treatment with interferon alfa and ribavirin was started. While the physician was on treatment, HCV-RNA test results from plasma taken the day treatment was started became available. HCV-RNA was undetectable by quantitative bDNA assay, undetectable by qualitative polymerase chain reaction (PCR) and undetectable by transcription mediated amplification (TMA). A dilemma arose at this point: should the patient stop the treatment or continue the planned therapy? The physician decided to continue a 24-week course of treatment. Six months after the end of treatment, the physician was still HCV-RNA-negative and with a normal plasma ALAT level. The rationale of the decision to continue therapy is discussed. This information may be useful for clinicians confronted with a similar dilemma.

infections for various occupational groups in Amsterdam, 1986-1996][in
Dutch]. Nederlands Tijdschrift voor Geneeskunde 1998;142:2312-4.
ABSTRACT- Since 1986 the number of parenteral exposures to potentially infectious blood reported to the Amsterdam Public Health Service increases every year. The number of needlestick accidents increased significantly from 64 in 1986 to 166 in 1996 whereas the number of other exposures decreased from 59 to 44 in these years. The increase was mainly seen in nonhospital based (para)medics. A possible explanation of this increase is greater awareness of the potential infection risk with HIV, hepatitis B or C virus leading to a tendency to report more readily. This assumption is in contradiction with results of studies in hospital-based personnel where a decrease is observed as a result of educational programmes. Other explanations are a higher frequency of use of sharp instruments and (or) an increase in the workload. Out of a total of 1886 needlestick accidents in 1986-1996 one woman became HIV positive; she was deliberately infected by her ex-partner who injected her with blood of an AIDS patient, and one person contracted an hepatitis C virus infection: a policeman wounded by a needle used by a drug addict.
de Graaf R, Houweling H, van Zessen G. Occupational risk of HIV
infection among western health care professionals posted in AIDS
endemic areas. AIDS Care 1998;10:441-52.
SUMMARY- By the end of 1995, a total of 79 occupationally acquired HIV cases had been documented worldwide among health care workers. As part of a larger study on the sexual and occupational risks of HIV among Dutch expatriates, 99 medical professionals (48 physicians and 51 nurses, midwives, or anesthesia assistants) who had worked in AIDS-endemic areas were identified. 96% of physicians and 92% of nurses had last worked in sub-Saharan Africa--typically in rural areas or refugee camps. When tested upon return to the Netherlands, none of these health care professionals was HIV-infected. However, 71% of physicians and 51% of nurses experienced at least one percutaneous exposure (mean number, 2.0 and 1.9, respectively) during an average stay abroad of 2.3 and 1.2 years, respectively. 235 of the 337 accidents described involved solid needles. Given an estimated HIV prevalence in the patient population of 19%, an HIV transmission per accident of 0.3%, and 1.9 percutaneous exposures per year, the occupational HIV risk per health worker per year in countries with high HIV prevalence can be estimated as 0.11%. Most injuries occurred during routine acts and tended to be self-inflicted as a result of negligent needle disposal, recapping errors, cleaning materials for reuse, carelessness due to fatigue, or rushing. Accidents with solid needles were significantly more likely to occur if more procedures were performed, the stay abroad was longer, co-workers were local, and management consisted of local personnel. Worry about occupational exposure to HIV was reported to occur sometimes in 68% of physicians and nurses, regularly in 12%, and often in 6%. HIV prevention programs for health workers should address not only how to prevent occupational exposure, but also how to prepare for the emotional responses to exposure and the consequences this may have for sexual behavior.

infection and health care workers in the tropics. Trop Doct
SUMMARY - A literature review revealed 33 reports of health care workers who have contracted HIV infection as a result of their work. Four of these were expatriate doctors who had worked in Africa. The commonest mode of transmission was needlestick injury, but several infections acquired through contact or skin or mucous membrane with infected blood have been reported. In this paper we outline how the risk of HIV infection in a health care worker can be estimated for a given number of exposures. The formula is based on the known likelihood of transmission per needlestick, the seroprevalence rate among patients, and the number of needlestick injuries that occur. We also suggest a list of measures by which the risk of HIV transmission to hospital staff can be minimized.

Naghavi SH, Sanati KA. Accidental blood and body fluid exposure
among doctors. Occup Med (Lond) 2009;59(2):101-6.
AIM: To study the epidemiology and time trends of blood and body fluids (BBF) exposures among hospital doctors. METHODS: A 3-year study was carried out using data from the Exposure Prevention Information Network of four teaching hospitals in the UK. RESULTS: One hundred and seventy-five cases of BBF exposures in doctors were reported over the 3-year study period. Eighty-one (46%) occurred in senior doctors and 94 (54%) in junior doctors. Junior doctors had a higher rate of BBF exposures compared to senior doctors: 13 versus 4 incidents per 100 person-years, respectively (relative risk 3, 95% confidence interval 2-4). The most frequent setting for BBF exposures among senior doctors was the operating theatre/recovery (59%). Among junior doctors, it was the patient room (48%). The commonest original reason for use of sharps by junior doctors was the taking of blood samples (42%). Among senior doctors, it was suturing (41%). CONCLUSION: While ongoing training efforts need to be directed towards both junior and senior doctors, our data suggest that junior doctors are at higher risk of BBF exposures and may need particular attention in prevention strategies. An improvement in the safety culture in teaching hospitals can be expected to reduce the number of BBF exposures.
Thomas WJ, Murray JR. The incidence and reporting rates of
needle-stick injury amongst UK surgeons. Ann R Coll Surg Engl
ABSTRACT - INTRODUCTION: Needle-stick injuries are common. Such accidents are associated with a small, but significant, risk to our career, health, families and not least our patients. National guidelines steer institution-specific strategies to provide a consistent and safe method of dealing with such incidents. Surgeon-specific guidelines are not currently available. We have observed that hospital sharps policy is often considered cumbersome to the surgeon, resulting in on-the-spot decision making with potential long-term implications. By their essence, these decisions are inconsistent, not reproducible and, thus, we believe them to be unsafe. The under-reporting to occupational health departments is well documented. Current surgical practice has the potential to expose the surgeon to unnecessary risk. The aims of this study were to establish the true incidence of contaminations caused by needle-stick injury in our hospital and to assess how well current protocols are really implemented. SUBJECTS AND METHODS: We identified all surgeons of consultant, non-career staff grade (NCSG) and registrar grade working in a large 687-bed district general hospital serving a population of 550,000, in the UK. We designed a retrospective, anonymous 30-second survey. Surgeons' awareness and opinion of local policy was sought in a free-text section. RESULTS: Of the 98 surgeons in the hospital, 77% responded to the questionnaire and 44% anonymously admitted to having a needle-stick injury. Only 3 of the 33 (9%) who sustained an needle-stick injury said that they followed the agreed local policy. Twenty-three surgeons (70%) performed first aid type procedures such as informing scrub nurse, changing needle and gloves. Seven surgeons (21%) simply ignored the incident and continued. Forty-three surgeons commented on the policy's nature with only 9 who regarded it as 'user friendly'. CONCLUSIONS: Needle-stick injury is still a common problem, particularly in the surgical cohort and remains significantly under-reported. The disparity between hospital sharps policy and actual surgical practice is considered and an explanation for the difference sought. Without this awareness of 'real-life' surgical practice, the occupational health figures for sharps injury will always tell a rosy story under-estimating a real problem. We strongly advocate universal precautions in the operating theatre. However, we acknowledge that sharps injuries will occur. We should remain vigilant and act upon contaminations without surgical bravado but with mater-of-fact professionalism. This includes regular review of policy and, particularly, promotion of surgical awareness.
Varsou O, Lemon JS, Dick FD. Sharps injuries among medical students
Occ Med 2009;59(7):509-11.
ABSTRACT - Background:Medical students may be at risk of sharps injuries for several reasons. These exposures can transmit a range of blood-borne pathogens including hepatitis B, hepatitis C and human immunodeficiency virus. Aims: To evaluate medical students' knowledge regarding the prevention and management of sharps injuries and their experience of such exposures in the calendar year 2007. Methods: A cross-sectional, web-based, survey of fourth and fifth year medical students enrolled at the University of Aberdeen in Scotland. All students were at the mid-point of their year of study. An invitation e-mail and two electronic reminders were sent, on specified days, to the study population. These contained a summary of the study and the link to the anonymous questionnaire. Results: Of the 395 medical students e-mailed, 238 (60%) responded. When compared with fourth year medical students, final year students had higher mean knowledge scores for sharps injury management (P < 0.01). Of total, 18% reported resheathing used needles and 31% reported disposing of sharps for others, indicating poor compliance with standard precautions. In the event of an injury, 29% stated that they would scrub the wound. Only 44% were familiar with policies for reporting exposures. In all, 11% of students had experienced at least one contaminated sharps injury in 2007 and, of those, 40% had reported the most recent incident. Conclusions: Medical students are at risk of sharps injuries and their knowledge regarding the prevention and management of these exposures is limited: training on these issues should be increased.

occupational exposures: epidemiology and factors associated with
initiation of post-exposure prophylaxis. J Epidemiol Community Health.
BACKGROUND: Occupational exposures to bloodborne viruses are very common. Whilst occupational HIV transmissions are rare, the serious physical, psychological and cost implications of potential transmission make this an important public health topic. European and UK guidelines recommend HIV post-exposure prophylaxis (PEP) as a valuable tool of preventing occupational HIV infection. Yet one in five UK healthcare workers did not initiate PEP despite having been exposed to an HIV-positive source patient. The aim of the study is to examine factors associated with PEP uptake behaviour. METHODS: The study is based on an analysis of the UK Health Protection Agency surveillance database of 'Significant Occupational Exposures to Bloodborne Viruses in Healthcare Workers'. Associations between possible predicting factors and PEP-uptake have been examined with univariate analysis and logistic regression modelling. RESULTS: Univariate analysis and logistic regression found significant associations between PEP-uptake and visible blood on the device (p<0.0001) and a linear relationship with increasing injury depth (p<0.0001). Doctors were significantly more likely to start PEP than nurses (OR 1.88, 1.16; 3.02). Multiple imputation of missing values did not significantly alter these results. CONCLUSIONS: PEP-uptake was associated with known transmission risk factors, suggesting awareness of current guidelines. The significant differences in PEP-uptake across occupation categories may be due to differential risk perceptions or other underlying factors. This is the first national study to examine PEP-uptake following occupational exposures to HIV. Further research and exploration of these findings are warranted, to understand the role of PEP-uptake behaviour in preventing occupational HIV transmission.
Au E, Gossage JA, Bailey SR. The reporting of needlestick injuries
sustained in theatre by surgeons: are we under-reporting? J Hosp Infect
ABSTRACT - Surgeons frequently sustain needlestick injuries when operating. The aim of this study was to evaluate the incidence and reporting rate of needlestick injuries at one institution. A questionnaire was distributed anonymously to 69 surgeons of all grades and specialties in a district general hospital in the UK. The questionnaire was returned by 42 surgeons (60.9%). There were 840 needlestick injuries over two years, of which 126 caused bleeding. Senior surgeons who spent more hours operating per week had a higher rate of needlestick injuries compared with junior surgeons (29.1 vs 6.59 injuries per surgeon over two years). Of the total number of injuries, 19 (2.26%) were reported to Occupational Health according to the surgeons questioned, but only six reported incidents were found in the Occupational Health records. Junior surgeons were significantly more likely to report needlestick injuries than senior surgeons (9.82% vs 1.10% of injuries reported, P=0.0000045). The main reasons for failure to report needlestick injuries were due to the lack of time and excessive paperwork. Seventy-three percent of surgeons did not routinely use double gloves when operating, mainly because of decreased hand sensation. The rate of needlestick injury reporting by surgeons at this institution is extremely low. Previous studies have shown a higher reporting rate suggesting that, despite awareness of blood-borne infections, surgeons are still not following recommended protocols.
Blenkharn JI, Odd C. Sharps injuries in healthcare waste handlers.
Ann Occup Hyg 2008;52(4):281-6.
ABSTRACT - Clinical waste disposal carries with it a risk of serious and possibly life-threatening infection. Combining confidential questionnaires and structured interviews with discrete observation, the attitudes and approach to safe handling of bulk clinical wastes by staff in a specialist waste treatment facility were assessed. With particular attention to glove use and hand hygiene, observations were supplemented by review of group-wide accident and incident records, with emphasis on sharps injuries and related blood and bloodstained body fluid exposures. Deficiencies in glove selection and use, and in hand hygiene, were noted despite extensive and on-going training and supervision of waste handlers. Though ballistic puncture-resistant gloves protect against sharps injury, these were uncomfortable in use and were sometimes rejected by waste handlers who preferred thin-walled nitrile gloves that were more comfortable in use though provide no resistance to penetrating injury. Among the waste handlers working for a single specialist waste disposal company, sharps injuries (n = 40) occurred at a rate of approximately 1 per 29 000 man hours. Injuries were caused by hypodermic needles from improperly closed or overfilled sharps boxes (n = 6) or from sharps incorrectly discarded into thin-walled plastic sacks intended only for soft wastes (n = 34). Most injuries occurred to the fingers or hands. No seroconversions occurred, though two individuals suffered anxiety/stress disorder necessitating prolonged leave of absence with professional counselling and support. Glove use and hand hygiene must feature prominently in the on-going training of waste handlers. Though ballistic gloves afford protection against sharps injury, the initial segregation and safe disposal of clinical wastes by healthcare professionals must provide the primary control measure. Despite robust and unambiguous legislation and good practice guidelines, serious errors by healthcare staff that result in the disposal of hypodermic needles and other sharps to thin-walled plastic waste sacks places waste handlers at risk of bloodborne virus infection. Further improvement in the standards of waste segregation and disposal by healthcare professionals are still required to protect ancillary and support staff and waste handlers working in the disposal sector.

in primary care in Wales. Journal of Public Health (Oxford, England)
BACKGROUND: Accidental needle-stick injuries (NSIs) are a hazard for health-care workers and for the general public. OBJECTIVES: To estimate the presentation rate of NSIs to general medical practices, their relation to practice characteristics, and review practice policies for managing NSIs. METHOD: Descriptive study using logistic regression analysis. RESULTS: Annual rates of 2.73 (95% CI 2.08, 3.50) occupational NSIs per 100 clinical practice staff and 2.14 (95% CI 1.39, 3.13) non-occupational NSIs per 100,000 practice population were recorded. Stepwise logistic regressions showed that chance of a practice reporting at least one occupational NSI in previous five years was best predicted by being a single-handed practice (decreased odds). In contrast, the chance of a practice reporting at least one non-occupational NSI was best predicted by being a rural practice (increased odds). About one in five practices possessed no written policy on managing NSIs. Stepwise logistic regressions showed that the chance of a practice owning a NSI policy was best predicted by being located in an LHB area with a coastline (increased odds). CONCLUSION: NSIs are an important public health issue in Wales. We have tried to address the lack of guidance by developing new guidelines in Wales.
Casey AL, Elliott TS. The usability and acceptability of a
needleless connector system. British Journal of Nursing
ABSTRACT- Needleless connectors were introduced into clinical practice to reduce the rate of needlestick injuries to healthcare workers (HCWs). There have, however, been limited reports of user acceptability of these devices. The usability and acceptability of the Clearlink needleless connector (Baxter Healthcare, UK) was therefore completed by HCWs at University Hospital Birmingham NHS Foundation Trust following a 12-month clinical evaluation. Seventy percent (28/40) of HCWs reported that they would prefer to use Clearlink needleless connectors rather than conventional luers caps, 15% (6/40) would use either, and only 15% (6/40) preferred to use luer caps. In total, 85% of HCWs reported that Clearlink was acceptable to use in the clinical situation. The results demonstrate that comprehensive training and technical support both before and after new device implementation were essential to ensure a smooth transition.
Cutter J, Gammon J. Review of standard precautions and sharps
management in the community. British Journal of Community Nursing
ABSTRACT- Standard precautions are imperative for staff and patient safety and provide a basis for sound infection control practice in all health-care settings. One key element of these precautions relates to the safe handling and management of sharps to prevent occupational acquisition of blood-borne viral infection. Many inoculation injuries could be avoided by following standard precautions whenever contact with blood or body fluids is anticipated. However, evidence suggests that compliance with standard precautions is inadequate. With the modernization of the health service in the UK, community health care is becoming more complex, potentially increasing the risk of inoculation injury to community nurses. Although compliance with standard precautions in hospitals is well documented, there is limited research specific to community nurses. This review examines compliance with standard precautions by community nurses and discusses some strategies aimed at improving compliance with one of the key elements of standard precautions, i.e. sharps management.
Davies CG, Khan MN, Ghauri AS, Ranaboldo CJ. Blood and body fluid
splashes during surgery - the need for eye protection and masks. Annals
of the Royal College of Surgeons of England 2007;89:770-2.
ABSTRACT- Introduction: While most surgeons make an effort to avoid needlestick injury, some can pay little attention to reduce the potential route of infection occurring when body fluids splash into the eye. It has been shown that transmission of HIV, hepatitis B or C can occur across any mucous membrane. This study aims to quantify how frequently body fluids splash the mask and lens of wrap around protective glasses thus potentially exposing the surgeon to infection. Patients and methods: A prospective study was carried out by a single surgeon on all cases performed over a 1-year period. Protective mask and glasses were examined before and after operations. Results: A total of 384 operations were performed with 174 (45%) showing blood or body fluid splash on the lens. A high incidence of splashes was found in vascular surgical procedures (79%). All amputations showed splash on the protective lens. Interestingly, 50% of laparoscopic cases resulted in blood or body fluid splash on the protective lens. Conclusions: This study has shown a high incidence (45%) of blood and body fluid splashes found on protective glasses and masks. There was a very high incidence (79%) during vascular surgical procedures. With the prevalence of HIV and hepatitis increasing, it seems prudent to protect oneself against possible routes of transmission.

interventions on primary health care workers' knowledge of occupational
exposure to blood or body fluids. Occupational Medicine (Oxford)
ABSTRACT- Aim: To assess the impact of educational interventions on primary healthcare workers' knowledge of management of occupational exposure to blood or body fluids. Methods: Cluster-randomized trial of educational interventions in two National Health Service board areas in Scotland. Medical and dental practices were randomized to four groups; Group A, a control group of practices where staff received no intervention, Group B practices where staff received a flow chart regarding the management of blood and body fluid exposures, Group C received an e-mail alert containing the flow chart and Group D practices received an oral presentation of information in the flow chart. Staff knowledge was assessed on one occasion, following the educational intervention, using an anonymous postal questionnaire. Results: Two hundred and fifteen medical and dental practices were approached and 114 practices participated (response rate 53%). A total of 1120 individual questionnaires were returned. Face to face training was the most effective intervention with four of five outcome measures showing better than expected knowledge. Seventy-seven percent of staff identified themselves as at risk of exposure to blood and body fluids. Twenty-one percent of staff believed they were not at risk of exposure to blood-borne viruses although potentially exposed and 16% of exposed staff had not been immunized against hepatitis B. Of the 856 'at risk' staff, 48% had not received training regarding blood-borne viruses. Conclusions: We found greater knowledge regarding management of exposures to blood and body fluids following face to face training than other educational interventions. There is a need for education of at risk primary health care workers.
Sherwood CS. Needleguard systems: an evaluation. Journal of the
Royal Society of Health 2007;127:280-6.
ABSTRACT- Aims: The National Blood Service is responsible for ensuring that the NHS demand for blood products is met. The use of needles forms a fundamental procedure in the collection of blood. A common engineering control used to minimize needlestick injury is a needleguard. This study investigates the effectiveness of needleguards as a risk reduction measure. Injury rates, performance and the effectiveness of training are also addressed. Methods: The methodology adopted two techniques for collecting data, namely database analysis and questionnaire analysis. In examining the accident database, it was identified that the incidence of needlestick injuries fell when needleguards were introduced in 2001. However, a rise in injuries was observed over the 12 months of 2003. Results: Although the questionnaire showed that staff directly involved in the collection of blood believed that needleguards act to reduce the risk of injury, they also reported difficulties in the operation of the needleguard system. An association was identified between the perceived quality of training and the reported difficulties. It was also identified that training provided by external organizations had the least effect in reducing the operational difficulties. Conclusions: The study concludes that the use of needleguards as a successful control measure requires further investigation and that further research should be carried out to ensure the effectiveness of training in reducing injuries.
Adams D, Elliott TS. Impact of safety needle devices on
occupationally acquired needlestick injuries: a four-year prospective
study. Journal of Hospital Infection 2006;64:50-5.
ABSTRACT- A four-year prospective study was undertaken at the University Hospital Birmingham National Health Service Foundation Trust to evaluate the effect of the introduction of a range of safety hypodermic needle devices on the number of reported needlestick injuries (NSIs). Data on the number of reported NSIs for four clinical areas began in 2001. Following an enhanced sharps awareness strategy in 2002, the number of NSIs reduced from 16.9/100,000 devices used in 2001 to 13.9/100,000 devices (P=0.813). In 2003, when only standard training was provided, the number of NSIs increased to 20/100,000 devices. However, the subsequent introduction of three safety needle devices with concomitant training resulted in a significant reduction in the number of reported NSIs to 6/100,000 devices in 2004 (P=0.045). User satisfaction and acceptance of the safety needles was also very favourable. These results suggest that when safety needle devices are introduced into the clinical setting and appropriate training is given, a significant reduction in the number of occupationally acquired NSIs may ensue.

needlestick injury prevention among healthcare workers through safety
device usage and improvement of guideline adherence: expert panel
assessment. Journal of Hospital Infection 2006; 63:445-51.
ABSTRACT: A prospective survey was conducted over six months in order to estimate the proportion of reported occupational needlestick injuries sustained by National Health Service (NHS) Scotland staff that could have been prevented through either safety device introduction, improved guideline adherence, guideline revision or a combination of these. This survey involved the administration of a standard proforma to healthcare workers followed by an expert panel assessment. All acute and primary care NHS Scotland trusts, the Scottish Ambulance Service and the Scottish National Blood Transfusion Service were included. Proforma and expert panel assessment data were available for 64% of injuries (952/1497) reported by healthcare staff. These injuries were all percutaneous. The expert panel concluded that: 56% of all injuries and 80% of venepuncture/injection administration injuries would probably/definitely have been prevented through safety device usage, 52% of all injuries and 56% of venepuncture/injection administration injuries would probably/definitely have been prevented through guideline adherence and 72% of all injuries and 88% of venepuncture/injection administration injuries would probably/definitely have been prevented through either intervention. Multi-factorial analysis indicated that injuries sustained through venepuncture/injection administration were significantly more likely to be prevented through safety device usage [adjusted odds ratio (OR) 5.09, 95% confidence intervals (CI) 3.11-8.31 and adjusted OR 2.70, 95% CI 1.64-4.45, respectively], and significantly less likely to be prevented through guideline adherence (adjusted OR 0.26, 95% CI 0.11-0.60 and adjusted OR 0.31, 95% CI 0.12-0.78, respectively). Injuries sustained after completing procedures were significantly more likely to be prevented through safety device usage and guideline adherence. The study's findings support the need for improvements to staff's adherence to needlestick injury guidelines and appropriate implementation of safety devices for venepuncture and injection administration.
Elder A, Paterson C. Sharps injuries in UK injury rates, viral
transmission efficacy of safety devices. Occupational Medicine
ABSTRACT- Aims: To review the literature on sharps injuries and occupational bloodborne virus transmission in health care in the UK and the worldwide evidence for injury prevention of sharps safety devices. Methods: Literature review by online database and Internet resource search. Results: Twenty-four relevant publications were identified regarding UK reported sharps injury rates. UK studies showed as much as a 10-fold difference between injuries reported through standard reporting systems (0.78-5.15 per 100 person-years) and rates estimated from retrospective questionnaires of clinical populations (30-284 per 100 person-years). National surveillance data from England, Wales and Northern Ireland gives a rate of 1.43 known hepatitis C virus or human immunodeficiency virus (HIV) transmissions to health care workers per annum. When extrapolated, this suggests an approximate rate of 0.009 such viral transmissions per 1000 hospital beds per annum. Risk of infection from sources with no risk factors is extremely small (less than one in one million for HIV transmission based on Scottish data). Thirty-one studies on the efficacy of sharps safety devices showed evidence of a reduction in injuries,with the greatest reductions achieved by blunt suture needles and safety cannulae. Conclusions: Although injuries remain common, confirmed viral transmission in the UK has been relatively rare. The degree of under-reporting of sharps injuries may be as much as 10-fold. Safety-engineered devices are likely to be effective at injury reduction.

Occupational health departments have invested considerable resources in the prevention of these injuries, which can be very distressing to the affected individuals. We surveyed health care workers, i.e. doctors, nurses and operating department practitioners, in the operating theatre and critical care units of two UK hospitals located in the Midlands and Merseyside to compare attitudes and experiences. There were significant deficiencies in several aspects of the safe practice of universal precautions. These deficiencies were similar in the two hospitals surveyed and may reflect a national trend. We conclude that every individual, department and trust needs to reflect on their practice and address these deficiencies.

injuries. J Hosp Infect 2005; 60:374-7.
ABSTRACT: Healthcare workers (HCWs) including medical students are at risk of occupational exposure to blood-borne viruses following sharps incidents including needlestick injuries. The recent Department of Health guidelines recommend that all HCWs entering a career involving exposure-prone procedures should be tested for hepatitis C, making preventative strategies even more relevant. A survey of current medical students' knowledge regarding prevention of sharps injuries in Birmingham, UK was carried out to determine their awareness of these risks and to compare the findings with an earlier cohort of students. Two hundred and fifty-six medical students were enrolled into the study. Their knowledge of needlestick injury, prevention and management had significantly improved compared with the previous study. This demonstrates that intensive teaching and self-learning programmes can improve the knowledge of HCWs and reduce the number of needlestick injuries.

Needle-stick injuries in the National Health Service: a culture of
silence. J R Soc Med 2004 July; 97(7): 326-7.
ABSTRACT - Injury by contaminated sharp instruments and needles constitutes a major occupational hazard for healthcare workers. In a confidential survey at a district general hospital, 300 healthcare professionals were asked about their personal experience of needle-stick injury and their attitudes to reporting.279 individuals responded, of whom 38% had experienced at least one needle-stick (mean 1.8) in the past year and 74% had sustained such an injury during their careers (mean 3.0). Although 80% of respondents were aware that such incidents should be notified, only 51% of those affected had reported all needle-stick injuries. Doctors were less likely to report than nurses, despite a higher liability to injury.This survey adds to evidence of a culture of silence pertaining to needle-stick injuries. The consequent risks to health, and the ethical and financial implications, remain uncertain.
Watterson L. Monitoring sharps injuries: EPINet surveillance
results. Nursing Standard 2004;19(3):33-8.
ABSTRACT- Sharps injuries are one of the main types of accident sustained by NHS staff. The RCN's Be Sharp Be Safe campaign was launched in 2001 with the aim of reducing sharps injuries and includes a surveillance project to describe the current pattern of sharps injuries being experienced in participating trusts. This article gives an overview of the results from the second year of the surveillance project and indicates how the data can be used to help improve practice. Nurses emerge as the staff group reporting the highest proportion of injuries recorded in the study period. The most common sharps injury scenario involves nurses giving injections in the patient's room or ward area. Aspects of poor disposal practice and incidents involving the recapping of needles continue to result in injuries and are worthy of further investigation. Analysis of the data by location can highlight specific tasks which could be reviewed to identify safer working practices.

healthcare workers in England, Wales, and Northern Ireland to
bloodborne viruses between July 1997 and June 2000: analysis of
surveillance data. British Medical Journal 2001;322:397-8.
SUMMARY- Since July 1997 occupational health departments have been requested to complete a brief form outlining the circumstances of any work related exposure to potentially infectious material from patients who are known to be positive for HIV antibodies or hepatitis C antibodies, or for hepatitis B surface antigens. For exposures to HIV or hepatitis C virus, the follow up at six weeks includes more information about the incident, baseline testing of both the healthcare worker and the source patient, and, for exposure to HIV, details of post-exposure prophylaxis. A total of 813 initial reports were received of exposure of healthcare workers to bloodborne viruses between July 1997 and June 2000: 725 reports of exposure to only one of the bloodborne viruses, 83 to two, and five to all three. After records with missing information were excluded, the most commonly reported exposed groups were nurses and midwives (45% (308/678) of the health professionals exposed) and doctors (38% (255/678)) (table), and percutaneous injuries were the most commonly reported type of exposure (70%).

prophylaxis guidelines following HIV needlestick injury may increase
the risk of seroconversion. Br J Anaesth. 2000; 84:767-70.
ABSTRACT: Needlestick injury is relatively common amongst healthcare workers, particularly those, such as anaesthetists, who regularly perform invasive procedures. The risk of seroconversion following needlestick injury may be reduced by knowledge of body fluids that are high risk and knowledge of post-exposure prophylaxis following possible HIV-contaminated needlestick injury. A structured questionnaire was used to establish knowledge regarding high HIV risk body fluids and measures to be taken following needlestick injury in anaesthetists working in a large teaching hospital. Completed questionnaires were obtained from all 76 anaesthetists working in the department (39 consultant, 37 trainee/non-consultant). Only 45.2% correctly identified high-risk body fluids. Sixty-eight per cent of anaesthetists knew the appropriate first aid measures to be taken following needlestick injury. Only 15% of anaesthetists were aware that post-exposure prophylaxis (oral medication) should be administered within 1 h of injury. This study reveals a surprisingly poor knowledge of high-risk body fluids and action to be taken following needlestick injury. Timely post-exposure prophylaxis, after needlestick exposure to high-risk body fluids, is believed to reduce the risk of seroconversion to HIV. Ignorance of this may increase the risk of seroconversion to HIV for anaesthetists and other healthcare professionals.

appreciate the risks of infection due to needle stick accidents: a
hospital based survey. J Hosp Infect 1999;42(1):53-9.
ABSTRACT - One of the most important occupational risks to healthcare workers is exposure is to blood-borne viruses. This study examined nurses' perceptions of risk of contracting infection following single or multiple exposure to blood or body fluids. Two hundred and ninety nurses were surveyed using a questionnaire. One hundred and thirty-three responded; 85 worked in higher risk areas (ITU, Haematology, Haemodialysis and Neonatal Surgical Units) (Group A) and 48 worked in lower risk areas (medical wards, an orthopaedic and an ENT ward) (Group B). Forty-nine percent of subjects from group A and 60% of subjects from Group B believed that a needle stick injury with a needle contaminated with infected blood was an unlikely source of infection. Fifteen percent from group A and 20% from group B thought that infection with a blood-borne virus following a needle stick injury contaminated with Human Immunodeficiency Virus (HIV) infected blood was very unlikely. Twelve percent from group A and 10% from Group B did not know whether resheathing needles between use can provide protection against HIV. Sixty-seven percent from group A and 71% from group B disagreed with the statement that nurses are at higher risk of exposure to HIV/HBV than the other healthcare workers. Thirteen percent from group A and 5% from group B agreed with the statement, whereas 8% from group A and 5% from group B thought that nurses are at less risk. Only 22% from group A and 23% from group B would take more precautions if they knew that the patient had HIV/HBV infection, whilst 11% and 8% respectively admitted that they would take special precautions only when the patient has clinical symptoms of HIV/HBV infection. The findings suggest that these nurses would benefit from further education regarding infection from blood-borne viruses.
Gyawali P, Rice PS, Tilzey AJ. Exposure to blood borne viruses and
the hepatitis B vaccination status among healthcare workers in inner
London. Occupational and Environmental Medicine 1998;55:570-2.
ABSTRACT- Occupational exposure to blood borne viruses was examined during one year at a London teaching hospital. A total of 236 incidents occurred of which 83% were related to sharps, 32% were clearly avoidable, and 7% involved an infected source patient. Overall uptake of hepatitis B vaccine was 78% but it was particularly low in paramedical (70%) and domestic staff (45%). Continued effort needs to be applied to improve uptake of hepatitis B vaccine and to maintain high standards of control of infection.
Matthew IR, Frame JW. Sharps injuries involving a sheathed needle.
British Dental Journal 1997;183:70-1.
ABSTRACT- Two dental nurses each sustained a sharps injury while attempting to remove the sheathed needle from a used dental local anaesthetic syringe. The needle had been bent inadvertently during use. Neither of the dental nurses were aware that the needle had perforated the side of the sheath during resheathing. This incident emphasises the need for constant vigilance during the disposal of sharps and for the routine avoidance of direct contact with sheathed or unsheathed needles and other sharps after use.

Randomized trial of blunt-tipped versus cutting needles to reduce glove
puncture during mass closure of the abdomen. Br J Surg
ABSTRACT - Eighty-five consecutive patients were randomized to undergo mass closure of the abdomen with no. 1 polydioxanone mounted on either a blunt-tipped (n = 46) or cutting (n = 39) needle. Gloves were changed before closure and tested for perforation afterwards using standard air or water techniques. Fourteen pairs of gloves were punctured when using a cutting needle, and three pairs when a blunt-tipped needle was used. The majority of punctures were to the non-dominant glove. The surgeon was aware of the puncture in eight of the 14 instances involving a sharp needle and in one of the three involving a blunt-tipped needle. Blunt-tipped needles, while not eliminating the risk, significantly reduced the incidence of surgical glove puncture (P < 0.001, Fisher's exact test). The use of cutting needles for abdominal closure should be abandoned.
Williams S, Gooch C, Cockcroft A. Hepatitis B immunisation and blood
exposure incidents among operating department staff. British Journal of
ABSTRACT- A questionnaire was sent to all 158 staff of the operating department of a London teaching hospital to confirm their hepatitis B immunization status and establish the number of incidents involving exposure to blood during the preceding 4 weeks. Of these personnel, 104 (66 per cent) were known to be immune to hepatitis B either through immunization (97) or previous infection (seven). A further 23 (15 per cent) had completed a course of immunization but their seroconversion had not been checked. There were 26 sharps injuries sustained by 14 (12 per cent) of 119 staff and 240 other exposures to blood. Four of the sharps injuries had been reported. Staff known to be immune were more likely than those with unknown or negative immunity to report incidents (20 versus 0 per cent (95 per cent confidence interval of difference 2-38 per cent)). Doctors sustained more non-sharps exposures to blood than others (47 versus 23 per cent (95 per cent confidence interval of difference 7-40 per cent)). An important minority of operating department staff remains unimmunized against hepatitis B, although exposure to blood is common. Incidents are rarely reported and staff with unknown or negative immunity seem less likely to report than those known to be immune.
