The recent creation of a psychiatric unit in the hospital Broussais gives rise to reflection on what, according to the authors, could constitute the originality of such a treatment unit. It should not be used to satisfy all the requests for psychiatric care within the hospital itself, nor act in parallel with the specialized psychiatric departments established as such in psychiatric or general hospitals. The presence, however, of a group of psychiatrists working as a team in a general hospital, and having several beds for their own autonomous use, should enable the first approach to be made, under the best conditions, to pathological disorders produced by psychological disturbances which are not immediately recognized by the patient: somatic manifestations of anxiety or depression, psychosomatic disorders, behavioural problems such as alcoholism, or even suicide attempts. This clinical function cannot be dissociated from the daily therapeutic approach of the health team or from the conception of medical psychology training based on the true needs of general practitioners. It is also the starting point for a close collaboration with physicians and basic scientists in the field of medical research.
