Hepatitis C virus infection in healthcare workers: risk of exposure and infection.

Objectives: To determine the incidence of hepatitis C virus (HCV) infection among healthcare workers (HCWs) at a university hospital, the proportion of HCWs having non-A, non-B hepatitis (NANBH) who were anti-HCV positive, and the rate of HCV transmission following a HCV-positive needlestick injury.

Design: Longitudinal analysis of a dynamic (cohort) population.

Measurements: From 1980 through 1989, HCWs who had clinical NANBH were identified, and from 1987 through 1989, HCWs who reported a blood or body fluid exposure and the patients who were the source of the exposure were screened for antibodies to HCV.

Decline of clinical hepatitis B in workers at a general hospital: relation to increasing vaccine-induced immunity.

Hepatitis B is a well-recognized occupational hazard of health-care workers that can be prevented with vaccination. However, because data on the current epidemiology of hepatitis B virus (HBV) in this population are limited, no consensus exists regarding the requirement for immunization. In 1980-1989, 4,908 exposures of health-care workers to patients' blood and/or other body fluids were reported and evaluated at a general hospital.

Effect of educational programs, rigid sharps containers, and universal precautions on reported needlestick injuries in healthcare workers.

Objective: To evaluate the effect of infection control programs on reported needlestick injuries in a general hospital.

Design: Surveillance of all reported needlestick injuries at the University of Cincinnati Hospital was maintained by the infection control department for five years, from 1985 through 1989. Data on individual workers were collected, tabulated on a monthly basis, and reviewed continually to monitor trends in injuries.
