Impact of a Permanently Maintained Healthcare Multidisciplinary Facility (PASS-MULTI) on Unscheduled Readmissions at 12 Months for Persons in Precarious Situations.

Created in 1998, PASS departments are mostly intrahospital structures providing primary care to vulnerable patients. The main objective of the project will be to measure the impact of a multidisciplinary PASS benefiting from outpatient pharmaceutical interviews on the rate of unplanned rehospitalization of patients in precarious situations. The impact of the implementation of such a device will also be measured on other indicators of major interest in the course of care of the precarious patient: average lengths of stay, emergency room, improved continuity of treatment, quality of life of the patient related to his health, medication compliance, effective accessibility to social rights, qualitative improvement in the use of care, medico-economic efficiency of the intervention compared to existing practice. The study will be multicenter: 6 centers spread throughout France (Marseille, Paris, Nice, Toulouse, Poitiers and Bayonne).
