title: Need and demand in psychiatric emergency service utilization: explaining topographic differences of a utilization sample in Mannheim.
abstract: Up to now all investigations about the topographic distribution of psychiatric utilization rates ignore whether or not the patients really require care (need for care) respectively express that need by themselves (demand for care). To analyze utilization rates of the psychiatric emergency service of the Central Institute of Mental Health in Mannheim (CIMH), variables differentiating between need and demand for emergency care were included. The investigation is based on contacts in the psychiatric emergency service between 1982 and 1993 and comprises 6463 patients with 14,628 contacts. To operationalize the concepts of need and demand the items "instance of consultation", "reasons for consultation", "inpatient admission" and "rated urgency" from the standardized record system of the psychiatric emergency service were used. The association between need, demand and ecological, socio-demographic and distance-related factors were analyzed. The results show that demand for psychiatric emergency care is an important factor for explaining topographic differences in service utilization. Demand correlates with ecological, socio-demographic and distance related factors; need only correlates with age. The amount of demand also varies with specific mental disorders.
