Improving cervical cancer screening rates: a scoping review of resources and interventions.

INTRODUCTION: Cervical cancer mortality can be prevented through early detection with screening methods such as Pap and high-risk human papillomavirus (hrHPV) tests; however, only 81% of women aged 21-65 are up-to-date on screening. Many interventions to increase cervical cancer screening have been implemented, but there is limited understanding about which intervention components are most successful. METHODS: We conducted a scoping review of existing literature and available resources for cervical cancer screening interventions to identify gaps in the research. We used t tests and correlations to identify associations among intervention components and effect sizes. RESULTS: Out of nine studies, the mean overall effect size for interventions was 11.3% increase in Pap testing for cervical cancer screening (range = - 4-24%). Interventions that included community health workers or one-on-one interaction had the biggest effect size (p < 0.05). No associations with effect size were noted for literacy level, number of intervention components, or targeting by race/ethnicity. CONCLUSIONS: Future interventions may include educational sessions with community health workers or one-on-one patient interaction to improve cervical cancer screening. Further research is needed to establish effect sizes for large-scale interventions and hrHPV screening interventions.

Promoting colorectal cancer screening: A scoping review of screening interventions and resources.

BACKGROUND: Early detection through screening can reduce colorectal cancer (CRC) mortality, but approximately 33% of adults aged 50-75 are not getting screened as recommended. Many interventions to increase CRC screening have been tested, but clinical and community organizations may be challenged in identifying the optimum programs and program materials to increase screening and ultimately reduce CRC mortality. METHODS: We conducted a scoping review to characterize existing, US-based interventions to improve CRC screening and to identify gaps in the literature. We used t-tests and correlations to analyze the relationship between project features and intervention effect sizes. RESULTS: The overall effect sizes were + 16% for changes in screening by any modality. The average effect sizes were greater for projects with more components, used patient navigation, and provided free/low-cost testing. CONCLUSION: Interventions varied greatly in terms of follow-up time, test modality, and data sources. Organizations seeking to implement a program aimed at increasing CRC screening should consider both intervention components and relevant program materials.
