Document the effectiveness of the "Respite Site" program in relation to the current health system. Document in particular the number and type of constraints, lengths of hospitalization and mode of exit, as well as the exit destination of psychotic homeless people.

Between 2012 and 2015, the practice of "stress-related care" related to crisis situations increased by 15%, with about 90,000 people under duress making France one of the European countries where practice most under stress. Being homeless, from a visible ethnic minority, combined with the lack of alternatives in the territory are well-documented risk factors for being hospitalized under duress. A review of the 2015 literature has shown that out-of-hospital crisis sites achieve results equivalent to those of conventional hospitalization in terms of reduced symptomatology and would have better outcomes in terms of increase in remission and recovery times of professional activity and social inclusion, with greater efficiency. In Marseille, an experimental device has shown its capacity to propose an alternative to hospitalization, for this type of population.Running the lessons of this experiment and inspired by the experimentation Parachute, a new device experimental, called "Place of respite", This place proposes a model of resolution of the psychotic crisis where the person decides the type of care that she wish to receive. It is a device that is therefore an alternative to conventional psychiatric care under duress. The investigators formulate the hypothesis that alternative support to the resolution of the crisis by using the skills of people with disorders severe psychiatric conditions in the experimental "Respite site" decreases in the short term the number of hospitalizations and their duration, as well as the experience of the constraint in the course of care of these people, compared to the subjects who did not benefit from this device and could represent a model of crisis management / psychiatric emergency efficient with regard to the current offer.
