ABSTRACT

Introduction: Tuberculosis in health professionals is a global health problem. The purified protein derivative test (PPD) is a tool for initial assessment and follow up for the health staff. The aim of the study is to determine the incidence of positive PPD and the conversion rate. Methods: An ambispective, observational and descriptive study in pediatric resident physicians. The cohort was divided by year of residence and was applied to them, prior informed consent 2UI of PPD serially from May 2016 to January 2017. Data such as sex, age, cough, weight loss, fever, diaphoresis, chest X-ray report reactivity and PPD size were collected. Results: 103 applications in 43 residents. Nineteen (44%) men versus 24 (56%) women. Average age was 26.79 ± 1.3 years. Four subjects had a cough that last more than 15 days, representing 12% of the cohort. Ninety one percent of subjects have BCG. In the period May 2016 to January 2017 we found 20 subjects (46.5%) PPD (+), with a total conversion rate of 25.5% (11 subjects), the highest conversion rate was found in first year residents with a 11.63 % (five subjects). The statistical analysis of Cochran Q, and T Student McNemar was statistically significant p = 0.001. Conclusion: Increase in the conversion rate as the in-hospital stay progresses. Positive PPD rate within described mean and conversion rate higher than previously reported.
