Tuberculosis Recurrence: Associated Factors in an Epidemiological Surveillance Group of São Paulo

Abstract

Analyze the factors related to cases of tuberculosis (TB) recurrence in reports of the Epidemiological Surveillance Group XXIX/São José do Rio Preto/SP. This is a case-control study that analyzes pulmonary TB reports in the period between 1996 and 2014. Cases were reports of “Recurrence" and control: reports classified as "New" case and with "Healed" outcome. Odds ratio and multivariate analysis with 95% confidence interval were used to analyze the data. The variables of gender and adverse outcome in the 7^th month remained significantly associated with recurrence. Males showed 1.8 times greater risk (p = 0.0551) and individuals who obtained an adverse outcome in the 7^th month of treatment were 4.6 times more likely to recur (p = 0.0000). We found two factors associated with recurrence: male gender and adverse treatment outcome, which shows the need to assess the quality of the care provided.
