Title Historical risks of tuberculin skin test conversion among non-physician staff at a large urban hospital
Bibliographic information Sep. 2002, Vol.42, No.3, p.228-235. 33 ref.
Abstract Following cases of nosocomial transmission of Mycobacterium tuberculosis among workers at a 1000-bed urban hospital, an extensive evaluation was carried out of this risk among workers with potential exposure to tuberculosis patients or to contaminated biological samples. A retrospective cohort study was conducted to determine the incidence and risk of tuberculin skin test (TST) conversions among workers employed between 1 January 1990 and 30 September 1992. Personal, social and occupational risk factors were evaluated in 2,362 workers with potential exposure and 886 workers with no known exposure. The 33-month cumulative rate of TST conversion was 5.8% for potentially exposed workers and 2.0% for controls. Among workers with potential tuberculosis exposure, statistically significantly elevated risks were found for nurses, laboratory technicians, pharmacy workers, phlebotomists, housekeepers, clerks, emergency room workers and emergency responders.
