[Systems analysis as a necessary preliminary to improving psychiatric services].

The systems analysis approach to the work of a regional psychiatric service is described. Standard rehabilitation programs for principal groups of patients have been developed. These programs allow one to choose an optimal structure of the rehabilitation complex based on real requirements of the population. The complex includes a dispensary division, a hospital, a home treatment service, daytime and night wards, and workshops for occupational therapy.
