The purpose of this study is to integrate elements from existing interventions developed by our team into a single intervention (QUIT-AD), designed to improve smoking cessation and favorable HIV/TB treatment outcomes among individuals with HIV and/or TB in Cape Town, South Africa. If feasibility, acceptability, and preliminary efficacy are demonstrated, the intervention will be ready for large-scale effectiveness/implementation testing. This program will has the potential to dramatically improve public health by increasing the smoking quit rate and facilitating favorable HIV/TB treatment outcomes among patients with HIV and/or TB in resource limited South African settings.
