The author describes a practical set-up for practising psychiatry in a non-psychiatric department of a general hospital. Initially, patients were seen on an unorganized basis, each time psychiatric advice was asked for. Subsequently, a meeting was held each week, with all the staff members (physicians, nurses, social workers...) and the same consulting psychiatrist. This meeting serves several purposes: clinical evaluation of patients, training of staff members, exchange of information between hospital departments, and choice of treatment. The different situations leading to admission and the diversity of clinical pictures are described. Appropriate answers are more likely to be provided if each staff member is assigned clear-cut responsibilities.
