An outreach strategy to increase uptake of vaginal self-sampling for cervical cancer screening in older French women: The RIDECA interventional research protocol

Background: In France, approximately 40% of women, including menopausal women, do not participate in cervical cancer screening. Many studies and meta-analyses have shown that self-sampling devices for high-risk human papillomavirus (HR-HPV) testing are valuable tools to increase participation. The success of self-sampling screening strategies depends on several factors, including the manner and circumstances in which the women are invited to participate. The acceptability and effectiveness of these strategies should be evaluated before further implementation. Objectives: The primary objective is to evaluate the uptake of cervical cancer screening in under-screened women, based on a direct offer of a vaginal self-sampling device by a midwife. Design: RIDECA is an interventional research project located in the South of France. Methods and Analysis: Six hundred women aged 50–65 with no cervical smear or HR-HPV test for 3 years or more will be recruited at two sites. The device will be offered to enrolled women to utilize at home and return to the Montpellier Hospital laboratory for HR-HPV testing. Completion of self-sampling by women who have accepted the device and follow-up of those with positive HR-HPV DNA tests will be monitored. During recruitment, participants will complete questionnaires on their socio-economic environment and motivational factors based on the psychosocial I-Change model. Semi-structured interviews will be conducted with a sub-group to identify barriers and levers to participation. Statistical analyses will be conducted for the full research sample and for each recruitment site. Ethics: The project was approved by the Ethical Research Committee Ile de France VI and by the French Data Protection Authority. Discussion: The results will provide useful information on the effectiveness (acceptability, efficiency) of this outreach strategy and identify barriers and levers that facilitate its implementation. Registration: ClinicalTrials.gov (NCT04716127), January 20, 2021.

A Proximity-incentive Strategy for Cervical Cancer Screening

In France, cervical cancer screening is based on a cervical smear for women aged 25 to 30 years and on High Risk- HPV (HR-HPV) testing for women aged 30 to 65 years. One of the main concerns in France is poor attendance to this screening program, up to 40% of women, which led French Health Authorities to implement population-based organized cervical cancer screening (DO CCU), based on remind letters, starting in 2019. Our project is a complementary strategy to DO CCU based on direct proposal of a vaginal self-sample device for HR-HPV testing to non-attendee women while attending health care centers. Our hypothesis is that contacting under-screened women directly and proposing them a self-sample device to be used at home will increase their participation to cervical cancer screening. This project will be held in the Departments of Hérault and Aude, which are among those in the region of Occitanie (south of France) with the lowest participation to cervical cancer screening. Women aged 50 to 65 years with no cervical smear and/or gynecological examination for more than three years, will be recruited in two sites: in a mobile unit for breast cancer screening implemented in the whole Department of Hérault and in a Medical and Social Care located in a particularly deprived area of Aude (Limoux-Quillan). In each site, non attendee-women will be proposed by a trained mid-wife, a vaginal self-sample device to perform at home and send back by mail to the laboratory of the Hospital of Montpellier, which will perform HR-HPV testing. Women with positive HR-HPV DNA test will be asked to perfom a cervical smear and completion of follow-up will be monitored. The primary objective of this study will be to evaluate attendance of under-screened women to vaginal self-sampling for cervical cancer screening, i.e. the number of women who accepted a self-sample device among women to whom it has been proposed. A second objective will be to analyse psycho-social factors associated with cervical cancer screening in this population of non-attendee women, i.e. their socio-economic environment and the way women perceive and are implicated in cervical cancer screening. This secondary objective will be based on a specific questionnaire at recruitment and on semi-directive phone interviews in a sub-group of women. The efficacy of this screening strategy (number of women who performed vaginal self sample and sent it to the laboratory, and number of women who completed follow-up in case of a positive HR-HPV test) will also be monitored. The number of women to be recruited is 660. The total estimated duration of the project is 60 months, including 24 months for women's recruitment. Expected results from this project are: * An increase in participation to cervical cancer screening of non-attendee women aged 50 to 65 years in the Departments of Hérault and Aude. * Women's education about cervical cancer screening through discussion with the midwife during recruitment and information tools developed for the project * Information of local health staff and community-based associations about cervical cancer screening and the place of HR-HPV testing. * Identification of psycho-social factors and potential barriers to compliance to cervical cancer screening. * Identification of organizational and practical difficulties that must be overcome to improve preventive actions towards deprived populations.
