Optimizing Tobacco Cessation: A Systematic Review of Integration Approaches in Primary Care Settings

Introduction: Tobacco use remains a leading cause of preventable morbidity and mortality worldwide. Integrating tobacco cessation strategies into primary care presents a valuable opportunity to address this public health issue. This systematic review evaluates the effectiveness of integrated interventions – combining pharmacotherapy and behavioural counseling – compared to standard care within primary care settings. Materials and Methods: A comprehensive search of PubMed, EBSCO, and the Cochrane Library was conducted, yielding 188 records. Following duplicate removal, screening, and eligibility assessment, 10 randomized controlled trials were included in the study. The review aimed to evaluate the effectiveness of integrated tobacco cessation interventions and to summarize key implementation strategies and challenges. Results: The majority of included studies demonstrated that integrated interventions, especially those combining nicotine replacement therapy (NRT) with behavioral counseling, led to significantly higher cessation rates than standard care. Various models were employed, including high-dose NRT protocols, proactive opt-out strategies, and culturally adapted programs. Key barriers included limited resources, inadequate provider training, and restricted access to cessation medications. Facilitators of successful implementation were structured support systems, proactive outreach, and cultural tailoring. While few studies addressed cost-effectiveness directly, low-cost pharmacotherapies such as cytisine showed promising results in low-resource settings. Conclusion: Integrated tobacco cessation interventions in primary care significantly improve smoking cessation outcomes. Addressing implementation barriers and promoting cost-effective models are essential for widespread adoption.
