[Evaluation of a geriatric psychiatry ambulatory treatment concept].

After beginning the gerontopsychiatric ambulance the number of patients, who had to be treated in the psychiatric hospital could be reduced about 20% during one year. Nevertheless, the total number of ambulant and/or stationary treatments increased continuately as the years ago. More patients could be sent home or to their families after stationary therapy than before starting the ambulance, less patients had to be sent to nursing homes or the other hospitals. Especially patients with severe demential disorders had to stay in hospital for a shorter time (30%). The number of ambulant treated patients increased during the same time at a third, the number of consultations of other non-psychiatric hospitals at a sixth.
