Clinical Trial Summary

This cluster-randomized trial in Uganda will evaluate the effectiveness and implementation of a novel, peer-led TB education and counseling strategy to improve outcomes among persons with tuberculosis (TB) with and without HIV/AIDS and assess the social-behavioral mechanisms underlying the observed treatment effects.


Clinical Trial Description

Study Design Aim 1. The investigators will conduct a parallel cluster-randomized hybrid Type 2 effectiveness-implementation trial at 16 sites. Aim 2. Within the Aim 1 study, the investigators will nest a longitudinal observational study in both arms of the cluster-randomized trial to determine the feasibility, acceptability, and appropriateness of a peer-navigation strategy for TB-EC. The investigators will concurrently assess biological adherence using urine biomarkers) and will also perform a mediation analysis of social and behavioral factors (i.e., TB knowledge, perceived social support, general self-efficacy, HIV/TB stigma) to identify causal mechanisms of impact. Finally, the investigators will pilot and culturally adapt study instruments in a pilot study prior to the trial. Aim 3. The investigators will also conduct a qualitative and mixed methods studies to assess the implementation fidelity and context of the peer-navigation strategy for TB-EC: 1. Process evaluation of intervention fidelity to quantify the adoption, reach, implementation, and maintenance of the peer navigation strategy, 2. In-depth interviews with people with Tuberculosis (PWTB) with and without HIV, 3. In-depth interviews with and direct observation of peer navigators, and 4. Focus-group discussions (FGDs) with healthcare workers. The focus of this registration is Aim 1 and 2. ;
