Trends in psychiatric hospitalisation of people with schizophrenia: a register-based investigation over the last three decades.
The number of psychiatric beds has declined considerably in many countries over the past decades. Long-term studies on the impact of these health care changes for the severely mentally ill, however, are still scarce. This epidemiological study investigates the use of inpatient psychiatric services by people with schizophrenia, compared to that by people with other mental disorders. We used psychiatric register data of the Swiss canton Zurich to establish the annual treatment prevalence in the period 1977-2004. For patients with psychoses, the length of inpatient episodes decreased by half. The annual number of inpatient admissions doubled. The proportion of schizophrenia patients, which accounted for 36%-41% of all inpatient treatments up to 1993, dropped to 20% in 2004, while that of other psychoses remained about the same (8%-10%) throughout the study period. This contrasts with a 2-3 fold increase in other patient groups. The annual treatment prevalence for people with schizophrenia declined from 7.3 to 2.2 per 10000 population since the 1990s and affected patients of all ages and of both sexes equally. The treatment prevalence for other psychoses remained virtually unchanged (1.3 per 10000). For all other mental disorders, there was an up to twofold increase. The study suggests that the downsizing of psychiatric hospitals has resulted in a far-reaching redistribution of overall inpatient treatment resources. The considerable decrease in inpatient treatment for people with schizophrenia emphasizes the need to further investigate the current state of coverage for and the appropriateness of health care available to this patient group.
