Nosocomial tuberculosis in hospital staff. The size of the problem in a Hong Kong chest hospital.
In the past three decades, among 831 staff (over 6,862 staff-years) under regular chest radiographic survey in the Grantham Hospital, Hong Kong, the cumulative incidence of active pulmonary tuberculosis requiring treatment was 27 (belonging to 23 staff). Number of cases detected per year ranged from 0 to 3. The mean duration from the beginning of employment to the first evidence of disease was 6.43 years. Although this incidence is low, yet the hospital caters for quite a large number of patients with bacteriologically confirmed tuberculosis, we feel that the active screening program for hospital staff should be maintained, and that review of the situation is also recommended.
