Abstract
Evidence suggests that social protection policies such as Brazil's Bolsa Família Programme (BFP), a governmental conditional cash transfer, may play a role in tuberculosis (TB) elimination. However, study limitations hamper conclusions. This paper uses a quasi-experimental approach to more rigorously evaluate the effect of BFP on TB treatment success rate. Methods Propensity scores were estimated from a
complete-case logistic regression using covariates from a
linked data set, including the Brazil’s TB notification system
(SINAN), linked to the national registry of those in poverty
(CadUnico) and the BFP payroll.
Results The average effect of treatment on the treated
was estimated as the difference in TB treatment success
rate between matched groups (ie, the control and exposed
patients, n=2167). Patients with TB receiving BFP showed
a treatment success rate of 10.58 percentage points
higher (95% CI 4.39 to 16.77) than patients with TB not
receiving BFP. This association was robust to sensitivity
analyses.
Conclusions This study further confirms a positive
relationship between the provision of conditional cash
transfers and TB treatment success rate. Further research
is needed to understand how to enhance access to social
protection so to optimise public health impact.
