What this trial studies

This project aims to enhance smoking cessation strategies for individuals living with HIV by integrating four evidence-based components into existing HIV care in South Africa. The study will assess the effectiveness of intensive behavioral counseling, peer support, combination nicotine replacement therapy, and varenicline in a randomized trial involving 660 adults. Participants will be recruited from selected clinics and will undergo a 12-week intervention period. The trial will also evaluate the implementation and cost-effectiveness of these interventions across diverse settings in Gauteng.

Why it matters

Potential benefit: If successful, this study could significantly improve smoking cessation rates among people living with HIV, leading to better health outcomes.

How similar studies have gone: Other studies have shown success with integrated smoking cessation interventions in similar populations, indicating a promising approach.
