Trends in first admissions to a general psychiatric hospital from 1980 to 1993

J. Spijker, J. van Limbeek, J.F.J. Jonkers, W. van Tilburg

In this study an analysis was made of possible trends in first admissions to a general psychiatric hospital (GPH) in the Netherlands in the period 1980-1993. Data were obtained from the Stichting Informatievoorziening Gezondheidszorg (SIG) in the Netherlands (SIG: Foundation for Information on Health Care). In the so-called PIGG-registration the SIG keeps, among other things, records on admissions to GPHs. To describe the pattern seen in the observed data a poisson regression was used. The incidence of admissions to a GPH showed a decline. Based on the observed incidence rates this decline is about 18%. Corrected for age and gender influences the decline is 23%.
