ABSTRACT

Introduction: tuberculosis is traditionally considered as a professional disease in health care workers. Objective: to evaluate the individual and collective tuberculosis infection risk by areas or departments in the National University Pneumologiic Hospital of Havana, Cuba. Methods: the individual risk was assessed during 2008-2009 by means of a survey administered to the staff that includes personal data, labor location and exposition to M. tuberculosis, and a Tuberculin Skin Test (TST) was applied to 112 of them. A ≥ 10 mm cut-off point was used for positivity. The collective risk was measured in each area or department by the prevalence of TB infection, the tuberculin conversion rate and the number of tuberculosis cases hospitalized per year. Results: of the 183 surveyed workers, 60.7 % had workers for more than 5 years in the institution. Of the 64 negative workers in the previous survey, 34.4 % became positive in this survey. The latent TB infection prevalence was 50.8 % (CI 95 %: 43.36--58.23); higher prevalence found in nurses (64.7 %-CI 95 %: 38.6- -84.7) and lower in health non-related technicians(30 %-CI 95 %: 8.1-64.6). Half of the departments or areas (17/34) were evaluated as high risk, 23.5 % as intermediate risk, 11.8 % as low risk and 14.7 % as very low risk. Conclusions: the National Pneumologic Hospital, as it was expected, is a high risk facility for Micobacterium tuberculosis infection that may affect its workers, and most of its areas pose a potential risk potential for the staff working there.
