[Involuntary admissions in emergency psychiatric institutions. A comparison between the county of Hedmark and the Ullevål sector in Oslo].

In this paper we compare the acute psychiatric wards in Hedmark county and the catchment area of Ullevål hospital with regard to involuntary hospitalizations and admission rates for psychosis during the period 1989-94. In the former area the percentage of involuntary admissions decreased from 58% to 48% during the period, but in the Ullevål catchment area it remained fairly stable at 85%. The latter area showed a higher percentage of involuntary hospitalizations for both psychotic and non-psychotic patients. The admission rate for psychotic patients was higher in the Ullevål catchment area and tended to increase in the course of the study period. We relate our findings primarily to a higher incidence of psychiatric disorders in a city like Oslo. Structural differences in psychiatric and primary care, especially for long-term patients may also be a contributory factor.
