Using Multiphase Optimization Strategy (MOST) to Optimize a Cost-effective, Sustainable and Scalable Smoking Cessation Package for Smokers in HIV Clinical Care

This study will utilize Multiphase Optimization Strategy (MOST) to optimize a smoking cessation treatment for HIV clinical care by directly targeting patient barriers to quitting and clinical care barriers to reaching and effectively treating a broad heterogeneous population of smokers living with HIV. The four intervention components will be aimed at barriers to quitting among smokers living with HIV and include Motivational Interviewing; Peer Mentoring; Text-messaging; Combination Nicotine Replacement Therapy. These components have shown promise in research but are under-utilized to help smokers living with HIV quit and have not been tested in an optimization trial. This study will also incorporate data to evaluate the fidelity, acceptability and feasibility of the interventions in the HIV clinical care context in order to identify the most cost-effective, sustainable and scalable tobacco treatment package for the care environment.
