Tobacco Cessation Tailored to Patients Living With HIV (PLWH) in Brazil

The overall goal of this feasibility study is to make adaptations to these evidence-based approaches in collaboration with PLWH and health care providers working with this population, and develop, implement, and evaluate the feasibility and scalability of a theory-based, culturally relevant tobacco cessation intervention for PLWH receiving care through the public health system in a southern town in Brazil (Londrina). This proposal will focus on the intervention development, pretesting, and feasibility testing. The primary outcome will be a 7-day point prevalence abstinence (defined as no tobacco use in the past 7 days and verified through measurement of salivary cotinine and exhaled carbon monoxide levels) at 6-month follow-up. We will also conduct detailed treatment fidelity and scalability assessments (acceptability, feasibility, potential reach and adoption, alignment with the strategic context) to inform a full-scale efficacy trial.
