Incidence and risk factors of occupational blood exposure: a nation-wide survey among Danish doctors.
Occupational blood exposures involves a risk of transmission of serious infections. We performed a nation-wide survey, to describe the incidence and risk factors of percutaneous (PCE) and mucocutaneous (MCE) blood exposures among hospital employed doctors in Denmark. Of 9,374 questionnaires, 6,256 (67%) were returned and 6,005 were eligible for analysis. The highest risk per person-risk-year (pry) was found in General surgery, Neurosurgery, Obstetrics-Gynaecology and Orthopaedic surgery (6.2-8.5 PCE/pry and 7.3-8.8 MCE/pry). The second risk group Anaesthesiology and Oto-rhino-laryngology (2.6-3.1 PCE/pry and 6.0-6.9 MCE/pry). Finally Pathology, Internal medicine, Radiology and Paediatrics had a considerable risk (0.8-1.3 PCE/pry and 1.3-2.9 MCE/pry). Potential risk factors were examined by Poisson regression. Employment as senior as compared to junior doctor was associated with a higher risk of PCE (RR 2.2) and MCE (RR up to 2.7 depending on experience) among surgeons and an increased risk of PCE in anaesthetists (RR 1.7). In contrast, senior physicians in Internal medicine, Radiology and Paediatrics had a several fold lower risk of PCE (RR 0.6) and MCE (RR 0.6 in males, 0.3 in females). Only 35% adhered to the basic principles of universal precautions (UP) and non-compliance was associated with a considerably increased risk of both MCE and PCE, especially in non-surgical specialties. In conclusion, we found an unacceptably high incidence of occupational blood exposures among Danish doctors. Non-compliance with UP was associated with an increased risk of exposure and efforts to improve compliance with UP as well as implementation and evaluation of other preventive measures are needed.
