[A hospital foundation for research on precariousness and social exclusion].

The hospital in Nanterre (92) offers a wide range of services for the reception, orientation and medical care of people in precarious situations on a daily basis, both in the social medicine department and in other departments. The medical teams wanted to create a structure that could document and analyze the life trajectories and experiences of people in precarious situations, but above all innovate, propose adapted systems and evaluate them, in order to develop knowledge and practices. The hospital foundation for research on precariousness and social exclusion was thus created at the end of 2019 [1], with the structuring support of the Île-de-France regional health agency.
