[Benchmarking in psychiatric acute care--a demonstration project in a hospitals network].

The aim of this project was to improve treatment processes and results in acutely ill inpatients within a network of nine psychiatric state hospitals of the Landschaftsverband Rheinland by introducing a benchmarking process. The project was based upon pre-existing measures of quality management. Patient groups were selected that were characterised by a severe clinical development or a high demand for mental health care services (alcohol abuse, depression of the elderly, schizophrenia).
