Brief Summary

The investigators are conducting a longitudinal mixed-method intervention study with a multi-center, multi-case explanatory sequential design. The ECEMSo study aims to identify the impact of health mediation on fostering healthcare utilization, in particular organized cancer screening uptake, by underserved populations living in informal housing in France.

Outcome Measures

Primary Outcomes (3)

• Impact of health mediation on healthcare utilization in people living in informal housing (PLIH) in France

  The difference in healthcare utilization by PLIH between groups 2 and group 3

  At six months follow-up

• Impact of the intervention on people living in informal housing (PLIH) uptake of organized cancer screening

  The difference in organized cancer screening uptake (breast cancer, colorectal cancer, cervical cancer) between PLIH in group 1 and PLIH in group 2

  At six months follow-up

• Health mediation conditions required to foster utilization of healthcare services among people living in informal housing (PLIH) in France

  The difference in organized cancer screening uptake (at 2 years since diagnosis for breast cancer and colorectal cancer, at 3 years since diagnosis for cervical cancer) between PLIH in group 1 and people living in informal housing in group 3

  At six months follow-up

Study Arms (3)

ECEMSo intervention

This group is composed of health mediators, the people living in informal housing they support and stakeholders. The ECEMSo intervention will be implemented in this group

Behavioral: Knowledge mobilization to facilitate the structuring of health mediation

Group 2 : No intervention

This group is composed of health mediators, the people living in informal housing they support and stakeholders. The ECEMSo intervention will not be implemented in this group.

Group 3 : No intervention

This group is composed of health workers, social workers, the people living in informal housing they support and stakeholders. The ECEMSo intervention will be implemented in this group.

Interventions

Knowledge mobilization to facilitate the structuring of health mediation BEHAVIORAL

The ECEMSo intervention involves knowledge mobilization to facilitate the structuring of health mediation throughout French territory, and the development of a co-designed effective action plan to facilitate cancer screening uptake by people living in informal housing. The action plan will, consider territorial specificities at the regional level. The ECEMSo project team will organize a seminar and three workshops. The aim of the seminar and workshops is to mobilize knowledge to facilitate i) the structuring of health mediation in the regions, and ii) the development of an action plan with health mediators and other stakeholders to foster organized cancer screenings uptake by underserved people. This action plan must match with the needs of people living in informal housing, and must be coordinated, suitable and feasible to implement, in terms of knowledge about people living in informal housing specificities and specific local collaborations
