A Peer Navigator Model to Improve Quit Attempts and Smoking Cessation Rates Among HIV-positive Smokers

Completed · Not applicable

Conditions studied: HIV

In brief

Effective antiretroviral therapy has led to an increased lifespan for persons living with HIV (PLWH), when diagnosed early and engaged in care. This transition to HIV as a chronic illness has resulted in cancer being a leading cause of morbidity and mortality in PLWH. The increased risk of cancer is due in part to a high prevalence of risk factors for cancer - most notably tobacco use. Smoking prevalence is substantially higher in PLWH (40%) compared with the general population (15%) and is associated with increased rates of lung cancers, and other malignancies. Furthermore, combined data from three national surveys showed that the proportion of deaths attributed to AIDS-defining cancers decreased from 2000 to 2010, while the proportion of deaths attributed to non-AIDS-related cancers increased significantly over the same period of time. Smoking cessation studies in PLWH have demonstrated disappointing outcomes, with low quit rates, poor adherence to therapy, and a lack of sustained abstinence. In an HIV and smoking review, it was suggested that research develop focused interventions that targets: 1) adherence to smoking cessation medications, 2) self-confidence for quitting, and 3) social support for smoking cessation. The investigators are proposing is specifically designed to address these 3 targets by using peer navigators to facilitate access to effective smoking treatments and to support abstinence. This study is highly innovative in its application of peer navigators to improve HIV-positive smokers' access to and utilization of existing resources to improve smoking cessation outcomes. The proposed study will provide initial evidence of whether targeting mechanisms of behavior change (self-efficacy and social support) during a quit attempt using peer navigators is effective at improving outcomes. If demonstrated to be successful, it has significant implications for the transformation of current clinical approaches to smoking cessation in HIV clinics. This approach could then be widely implemented to improve outcomes in this group of smokers.
