Psychiatry must have among its main aims to reintegrate in their own environment of life people with psychotic disorders, personality disorders and other serious disorder of the psychic sphere. We must be able to operate in places built ad hoc, that is, where time, space and procedures are marked with certainty and, as much as possible, managed firsthand. The environment must be constructed or modified in such a way as to make it unlikely the failure or discomfort. Patients also need to be strengthened in their ability to integrate in their environment and in the ability to cope with various life events. The goal is to transfer a first group of patients from large psychiatric hospital of La Habana to the territory, specifically in 2–3 already identified communities, to realize the rehabilitation projects that in 3–4 years can bring patients selected at their home or, alternatively, at self-managed apartments. The reference model of rehabilitative interventions is multimodal. The model explains the onset, course, prognosis and social functioning of the major mental disorders as a complex and mutually conditioning relation between biological, environmental and behavioural. The results will be evaluated over the next three years and will be the subject of future publications. A good practice cannot disengage from safe theoretical and methodological references. To show clearly and verifiably their work, operators must be trained before and during all phases of work, a job training, continuing education, which has as its primary objective the descriptive clarity and verifiability of results.
