Occupational blood-borne diseases in surgery

Background Human immunodeficiency virus (HIV), hepatitis B (HBV), and hepatitis C (HCV) infections are transmitted by blood exposure. Surgeons have been concerned about the risks of blood exposure in the operating room as a potential source of occupational infections from these viruses. The actual risk and frequency of operating room transmission remains poorly understood by many surgeons. Methods The pertinent recent literature on the pathophysiology, diagnosis, prevention, and treatment of HIV, HBV and HCV were reviewed to address the current understanding of these viruses as occupational risks to surgeons. Results HIV transmission to surgeons has not been documented in the United States by the Centers for Disease Control. HIV transmission from a surgeon to a patient in the environment of the operating room, as well as transmission from an HIV-infected surgeon to a patient, has not been documented. HBV infection of surgeons has declined with the general acceptance of the HBV vaccine. HCV infection remains a real risk for transmission in the operating room, given that no vaccine is currently available and that the overall number of chronically infected patients remains quite high. Conclusion The risk of occupational infection from known viral pathogens for surgeons is low, but it is not zero. Effective barriors, modified patterns of behavior, and prompt responses to blood exposure events are the best methods for prevention.
