  1. Evaluation of the two-step tuberculin skin test in health care workers at an inner-city medical center.

    Article - En anglais

    The increased rate of tuberculosis (TB) infection and transmission from patients to health care workers (HCWs) has brought awareness of the need for better surveillance programs.

    The two-step purified protein derivative (PPD) skin test decreases the misinterpretation of a « boosted reaction » as a recent infection with Mycobacterium tuberculosis in HCWs.

    We reviewed the medical records of 4082 HCWs at an inner-city medical center who had PPD skin-testing performed as a component of the TB medical surveillance program during the years 1994 and 1995.

    Of those HCWs tested, 3896 (95.4%) returned for the PPD skin-test evaluation.

    Of those 3896 HCWs, 3659 (93.9%) had a negative baseline PPD skin test, and 237 (6.1%) had a positive skin test.

    Of those HCWs with a negative baseline skin test, 252 (6. 9%) were eligible for the second PPD skin test.

    Of the 241 who returned for their second PPD skin-test reading, six (2.5%) had positive results.

    All six cases were foreign-born physician residents with a previous history of Bacille bilié de Calmette-Guérin (BCG) vaccination.

    We conclude that the two-step PPD skin test method is not indicted for HCWs at this urban medical facility.
