OBJECTIVE: Multidrug-resistant tuberculosis (MDR-TB) remains a serious public health problem worldwide. Accordingly, this study sought to identify individual, community and access to health services risk factors for MDR-TB.
METHODS: Retrospective cohort of all TB cases diagnosed between 2006 and 2016 in the state of São Paulo. A Bayesian spatial hierarchical analysis with a multilevel design was carried out.
RESULTS: It was identified that the history of previous TB treatment (Odds Ratios [OR]:13.86, 95% credibility interval [95% CI]:12.06-15.93), positive sputum culture test (OR: 5.26, 95% CI: 4.44-6.23), diabetes mellitus (OR: 2.34, 95% CI: 1.87-2.91), residing at a standard address (OR: 2.62, 95% CI: 1.91-3.60), positive sputum smear microscopy (OR: 1.74, 95% CI: 1.44-2.12), cavitary pulmonary TB (OR: 1.35, 95% CI: 1.14-1.60) and diagnosis performed due to spontaneous request (OR: 1.26; 95% CI: 1.10-1.46) were associated with MDR-TB. Furthermore, municipalities that performed HIV tests in less than 42.65% of patients with TB (OR: 1.50, 95% CI: 1.25-1.79), that diagnosed TB cases only after death (OR: 1.50, 95% CI: 1.17-1.93) and that had more than 20.16% of their population with income between ¼ and ½ of one minimum wage (OR: 1.56, 95% CI: 1.30-1.87) were also related to the MDR-TB.
CONCLUSIONS: Knowledge of these predictive factors may help to develop more comprehensive disease prevention strategies for MDR-TB, avoiding the risks expressed regarding drug resistance expansion.
