Family Health Strategy and determinants for the directly observed treatment of tuberculosis in Brazil: cross-sectional study with data from the Surveillance System, 2014-2016

Abstract

Objective. To analyze the association between tuberculosis determinants and the performance of directly observed treatment (DOT) in different coverage of the Family Health Strategy (FHS) in Brazil. Methods. Cross-sectional study with tuberculosis cases notified between 2014 and 2016 in the Information System on Diseases and coverage of the Family Health Strategy in the municipality of residence. Logistic regression was used. Results. 177,626 individuals were included. Having alcoholism (odds ratio (OR) 1.09 – confidence interval 95% (95%CI) 1.03;1.16), being deprived of freedom (OR=1.21 – 95%CI 1.12;1.32) and positive sputum smear microscopy (OR=1.15 – 95%CI 1.10;1.21) increased the chances of performing the DOT. When stratified by FHS coverage, these associations were emptied at the highest level of coverage. Conclusion. The DOT was associated with determinants of tuberculosis. However, it was not confirmed among residents in municipalities with greater FHS coverage.
