Occupational Exposures to Blood and Body Fluids among Health Care Workers at University Hospitals

Introduction Occupational exposure to blood and body fluids is a serious concern of health care workers and presents a major risk of transmission of infections such as human immuno-deficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV). Objective The aim of this study was to determine the frequency and circumstances of occupational blood and body fluid exposures among health care workers. Methods Cross-sectional study was conducted in three university hospitals in Belgrade. Anonymous questionnaire was used containing data about demographic characteristics, self-reported blood and body fluid exposures and circumstances of percutaneous injuries. Results Questionnaire was filled in and returned by 216 health care workers (78.2% of nurses and 21.8% of doctors). 60.6% of participants-health care workers had sustained at least one needlestick injury during their professional practice; 25.9% of them in the last 12 months. Of occupational groups, nurses had higher risk to experience needlestick injuries than doctors (p=0.05). The majority of the exposures occurred in the operating theatre (p=0.001). Among factors contributing to the occurrence of needlestick injuries, recapping needles (p=0.003) and decontamination/cleaning instruments after surgery (p=0.001) were more frequent among nurses, while use of a needle before intervention was common among doctors (p=0.004). Only 41.2% of health care workers had reported their injuries to a supervisor in order to obtain medical attention. 50.2% of health care workers were vaccinated with three doses of hepatitis B vaccine. Conclusion There is a high rate of needlestick injuries in the daily hospital routine. Implementation of safety devices would lead to improvement in health and safety of medical staff.
