Summary
Brief summary (as posted)
Organized breast cancer screening (OBCS) has been implemented nationwide since 2004 inFrance, but the participation rate remains low (51%) and inequities in participation were reported. Strategies as mobile mammography units could be effective to increase participation in OBCS and reduce inequities, especially in underserved areas in regard to this screening. Our main objective is to evaluate this device and to identify how to incorporate a mobile unit in the OBCS with a view to tackle territorial inequities in OBCS participation. The project will be conducted as a randomized controlled cluster trial in 2022-2024, in remote areas of 4 French departments. The main intervention is to propose an appointment at the mobile unit in complement to the current OBCS in these remote areas. In addition, few weeks before this intervention, local actors will carry out actions to promote OBCS with mobile unit specific information tools. This randomized controlled trial will provide a high level of evidence in assessing the mobile unit effects on participation and inequities.
