Protocol for a hybrid systematic review of the barriers and facilitators to implementing lung cancer screening in community settings.

Résumé fourni par la source

Background Lung cancer remains a leading cause of cancer-related mortality, with early screening using low-dose computed tomography (LDCT) substantially improving survival. However, participation in screening programmes remains low, particularly among underserved populations. This review aims to identify barriers and facilitators to the implementation of lung cancer screening within a behavioural and implementation science framework, to inform strategies that enhance community-based screening uptake. Methods This hybrid systematic review will be conducted in two phases. First, existing systematic reviews on global LDCT-based lung cancer screening recruitment strategies will be identified and screened against eligibility criteria. Second, we will search databases for individual studies not covered by the identified reviews. Studies must focus on community-based lung cancer screening recruitment, with the primary outcome being barriers and facilitators to implementation in these settings. Two independent reviewers will perform screening, selection, bias assessment, and data extraction. A thematic synthesis will be conducted using the Consolidated Framework for Implementation Research (CFIR), with evidence strength assessed using GRADE and CERQual. This protocol adheres to the Joanna Briggs Institute (JBI) Reviewers’ Manual and PRISMA-P guidelines. Conclusion The review will provide comprehensive insights into factors influencing the implementation of lung cancer screening in community settings, aiming to guide improvements in recruitment strategies and increase participation rates. Findings will be disseminated widely to researchers, healthcare practitioners, policymakers, and the public to support the effective implementation of lung cancer screening programmes.
