Yield of tuberculinic test between tuberculosis contacts in a basic health unit

Objective: To describe the Tuberculinic test yield, between contacts of Tuberculosis treated in a Basic Health Unit. Methodology: It is a descriptive, cross-sectional, quantitative study carried out in a Basic Health Unit, in the capital of a state in the Brazilian Northeast. Data collection was of the secondary type, using forms from the Health Department of the municipality, which was under the study, when the contacts of Tuberculosis performed the Tuberculinictest, in local action. Results: One hundred and thirty-three contacts were examined, of which 62.4% were households. According to the unit of origin, 72.2% were from the unit where the action was carried out; according to sex, 67.7% were female; 42.1% contacts obtained a result ≥ of 5mm from Tuberculinic test (TT). According to the TT result, contacts ≥ of 10 years old with a result ≥ of 5mm were 52.5% and p-value = 0.001. Conclusion: Tuberculinic test showed a 42.1% efficiency of reactors between the contacts. The unit, which hosted the action in Basic Health Unit, had a greater number of contacts, thus demonstrating that close access to the service optimizes screening and adherence to the exam.
