Background:

Since 1980s, several reports, based mainly in hospital registers, have suggested that the incidence of schizophrenia is decreasing. However, changes in capacity of mental hospitals, in admission policy and in diagnostic practice have not always been taken into account.

Aims:

Our aim was to study 1) how annual first admission rate for schizophrenia varied during a quick deinstitutiolisation period in Finland and 2) how it was associated with changes in admission policy and diagnostic practice.

Methods:

From the National Hospital Discharge Register, we identified 30 041, 15 to 64 year old patients admitted for the first time for schizophrenia to mental hospital in Finland between 1980 and 2003, as well as numbers of annual inpatient days in and all patients admitted to mental hospitals. Rates for all admitted patients and first-admitted schizophrenia patients (RFASpo) were calculated and analysed with Poisson regression analysis.

Results:

RFASpo decreased from 56.4 in 1980 to 29.5 in 1991, stayed stable until 1998 and slightly increased thereafter (30.8 in 1998 and 37.8 in 2003). Changes in RFASpo, coincided with changes in all admissions and periods of official diagnostic classifications. RFASpo varied also between gender and age groups.

Conclusions:

In 1980s, decrease of first-admission rate for schizophrenia seemed to be dependent on change in admission policy, in number of mental beds available and in diagnostic practice. In 1990s, increase of first-admission rate for schizophrenia may be associated with economic recession and increased number of beds for adolescents.
