SETTING: A private university hospital in South Korea. OBJECTIVE: To investigate the incidence of tuberculosis (TB) among health care workers (HCWs) employed at a university hospital in South Korea. DESIGN: The occurrence of TB cases among HCWs over a 6-year period (2001-2006) was reviewed. The prevalence of TB was compared with that of the general population using a prevalence ratio (PR) adjusted by age and sex. RESULTS: The study involved 8433 people. TB developed in 61 HCWs (0.72%). The prevalence ratio among all HCWs was 1.05 (95%CI 0.80-1.35). In occupational subgroups, the PRs for doctors, nurses and employees in other departments were respectively 0.58 (95%CI 0.30-1.01), 1.81 (95%CI 1.21-2.59) and 0.95 (95% CI 0.58-1.46). For nurses working in TB-related departments, the relative risk of developing TB was 3.4 times higher (95%CI 1.52-8.25) than for employees in other departments (P=0.005). The PR for nurses working in TB-related department was 5.1 (95%CI 3.23-8.42). CONCLUSION: Among HCWs, nurses working in TB-related departments were at increased risk of developing TB. This suggests that some TB develops via in-hospital infection.
