evaluation of the impact of case manager intervention on the 3-year psychotic episode recurrence rate in patients aged 16 to 30 years with a first psychotic episode.

Conditions: Psychotic Episode

Summary: the study investigators hypothesize that the intervention of case managers specifically trained in case management of early psychosis will change the paradigm of care of a first psychotic episode from the current organization of the care system. indeed, the creation of specific services for emerging psychotic disorders cannot easily be generalized throughout the country and requires specific funding. the intervention of case managers according to the recommendations of good practices will make it possible to propose the fundamental principles of early intervention to young patients and their families on a large scale throughout the territory, namely: personalized and proactive accompaniment, psycho-education of the pathology and treatments, involvement and support of the families, and support for socio-professional reintegration
