Introduction: Healthcare workers (HCWs) are at substantial risk of acquiring blood borne infections through contact with blood and other products of patients. Our main objectives were to determinant epidemiological characterists of occupational exposure to blood/body fluids and its related risk factors.

Methods: This cross sectional study was conducted on healthcare workers at risk of exposure to blood and other body fluids in three hospitals of Tehran University of Medical Sciences. Using a structured interview, all selected HCWs who were at risk were questioned about the exposure to blood born pathogens in the preceding year (Dec 2003–Dec 2004).

Results: Of the 900 HCWs, 391 (43.4%) had at least one occupational exposure to blood and other infected fluids during the previous year, with the total number of 467 exposures (52.88%) with annual rate of 0.5 exposure per HCW. The highest rate of occupational exposure was found among nurses (26.1%) and housekeeping staff (20.2%) and occurred most commonly in the medical and emergency wards (23.3%, 21% respectively). The rate of exposure in HCWs with less than 5 year experience was 53.8%.

Percutaneous injury was reported in 280 participants (58.8%). History of hepatitis B vaccination was positive in 85.93% of HCW among exposed workers. Sixty one percent had used gloves at exposure time. Hand washing was reported in 91.38% and infectious diseases specialist consultation in 29.38%. There were 72 exposures to HIV, HBV, HCV and exposure to HBV was the most common and in 237 of enrolled cases source was unknown.

Conclusion: Sharp injuries among HCWs are a widespread occupational problem. In this study, job categories, work experience and hospital ward were the most important risks for exposure. An effective and goal oriented education programme targeting HCWS, use of protective barriers, vaccination against hepatitis B are important way to prevent viral transmission among HCWs.
