Socioeconomic support to improve initiation of tuberculosis preventive therapy and increase tuberculosis treatment success in Peru: a household-randomised, controlled evaluation

For the first time in the modern era of tuberculosis control, the WHO's End TB strategy specifically integrates socioeconomic support for people affected by tuberculosis with existing biomedical interventions. However, there is little evidence of the impact of this approach on tuberculosis outcomes. We designed and implemented one of the world's first tuberculosis-specific socioeconomic support interventions, assessed its impact on tuberculosis prevention measures and treatment success, and refined the support for use in the Community Randomized Evaluation of a Socioeconomic Intervention to Prevent Tuberculosis (CRESIPT) project.
