OBJECTIVE: To review the existing evidence to identify the optimum methods for implementing human papillomavirus self-sampling to increase screening uptake for underserved groups.

SETTING: Specific groups are less likely to participate in cervical screening. These include individuals from low socioeconomic status groups, ethnic minority groups, younger age groups (25-29), older age groups (=50), with a physical disability, with a learning disability and with an LGBTQ+ identity. The advent of human papillomavirus self-sampling for cervical screening presents an opportunity to promote equitable access to screening. Implementation for human papillomavirus self-sampling can vary, for example, opt-out or opt-in approaches. However, it is unclear which of these is the best method of offering human papillomavirus self-sampling to underserved groups.

METHODS: Six databases were searched through May 2023. Studies comparing cervico-vaginal human papillomavirus self-sampling provision using different implementation strategies with the standard screening pathway in underserved groups were identified. A narrative synthesis was conducted.

RESULTS: In total, 4574 studies were identified; 25 studies were included, of which 22 were from high-income countries. Greater uptake was found for offering human papillomavirus self-sampling compared to standard clinician-based sampling. Directly mailing human papillomavirus self-sampling kits to participants resulted in higher uptake of screening than using an 'opt-in' approach or standard recall in low socioeconomic status and ethnic minority groups, and older women. Strategies that used community health workers or educational materials increased uptake in ethnic minority and low socioeconomic status groups.

CONCLUSIONS: Directly mailing human papillomavirus self-sampling kits to low socioeconomic status groups, ethnic minority groups and older women has the potential to increase uptake of human papillomavirus self-sampling. Using community health workers to offer human papillomavirus self-sampling should be considered for ethnic minority and low socioeconomic status groups. Further research exploring the preferences of younger women is needed.
