Attitudes towards latent tuberculosis among physicians in training: the role of BCG vaccination.

Prior work has demonstrated that international medical graduates physicians are less likely to recommend treatment of latent tuberculosis infection (LTBI) for themselves or their patients. Our objective was to measure differences in LTBI treatment attitudes among resident physicians when diagnosis is established with a positive tuberculin skin test (TST), as compared with a positive interferon gamma release assay (IGRA), and to determine whether a resident physician's personal history of Bacillus Calmette-Guerin (BCG) vaccination was associated with these attitudes. We conducted a cross-sectional survey of Internal Medicine resident physicians at two different training sites.
