Summary
Hepatitis B poses a significant occupational hazard for hospital personnel. Exposure to blood products containing Hepatitis B surface antigen (HBsAg) led to clinical hepatitis B in 3.0% of nonimmune employees.
Area of Science:
- Occupational Health
- Infectious Diseases
- Virology
Background:
- Hepatitis B virus (HBV) infection is a major global health concern.
- Healthcare workers are at increased risk of occupational exposure to HBV.
- Standardized protocols are essential for managing occupational exposures.
Purpose of the Study:
- To evaluate the incidence of hepatitis B among employees with occupational blood product exposures.
- To assess the risk of hepatitis B infection following exposure to HBsAg-positive blood.
- To determine the effectiveness of follow-up protocols for exposed employees.
Main Methods:
- Prospective evaluation of employees with known blood product or body fluid exposures.
- Identification of exposures involving HBsAg-positive blood.
- Follow-up of nonimmune employees for at least nine months post-exposure.
- Calculation of cumulative incidence of hepatitis B.
Main Results:
- 1,235 exposures occurred over 40 months, with 155 involving HBsAg-positive blood.
- Three (3.0%) of 101 nonimmune employees developed clinical hepatitis B after exposure.
- Cumulative incidence of hepatitis B was 106.0 per 100,000 employee years.
Conclusions:
- Hepatitis B is a significant occupational hazard for healthcare personnel in tertiary medical centers.
- Occupational blood product exposures pose a tangible risk of hepatitis B infection.
- Vigilant monitoring and standardized protocols are crucial for mitigating HBV transmission in the workplace.
