A global scoping review of interventions to increase participation in screening programmes for breast, cervical and colorectal cancer between 2016 and 2025
摘要
Implementation of timely and targeted health screening programmes is strongly aligned with the United Nations Sustainable Development Goals (SDGs) in promoting prevention, early detection, and timely intervention across populations. However, participation in breast, cervical, and colorectal cancer screening remains suboptimal and inequitable, and is increasingly challenged. This review synthesised global evidence on implementation interventions aimed at increasing screening participation and reducing disparities, to identify gaps that must be addressed to achieve screening targets.
MethodsThis scoping review was conducted and reported in accordance with PRISMA-ScR and the Joanna Briggs Institute methodological guidance. The Consolidated Framework for Implementation Research (CFIR) was used to extract and synthesise barriers and facilitators, while the RE-AIM framework for the performance of interventions. We used descriptive quantitative methods and a hybrid (deductive–inductive) thematic analysis to summarise and interpret the evidence.
ResultsOne hundred ten studies were included and identified ten intervention categories: educational, reminders, self-sampling, outreach, peer education and counselling, quality improvement, promotional messages, patient navigation and tracking, mass media, and multicomponent interventions. Barriers and facilitators to screening participation were assessed using the CFIR framework, while intervention performance was synthesised using RE-AIM components. Although most interventions demonstrated promising effectiveness, multicomponent interventions showed the greatest impact. However, most interventions were implemented in highly controlled settings, limiting their real-world applicability and scalability.
ConclusionFindings revealed important gaps in culturally responsiveness and real-world intervention approaches for cancer screening. Future research should prioritise pragmatic, culturally appropriate, and multiple component interventions, supported by sufficiently long follow-up periods to assess sustainability and real-world effectiveness.
