First-episode non-affective psychosis in a total urban population: a 5-year follow-up.
BACKGROUND
The aim of this study is to investigate incidence rates, treatment, and outcome of a total in- and outpatient population of 71 patients (of 18-45 years of age) treated for a first-episode psychosis (DSM-IV) in three catchment areas in Stockholm.


METHODS
The study is based on the investigation of records and databases and on information by staff members and patients.


RESULTS
The incidence rate was 34.8 per 100,000 inhabitants (aged 18-45 years) and 16.5 per 100,000 inhabitants (total population). Sixty percent were diagnosed with schizophrenia syndromes. At 5-year follow-up, 73 % of the patients in the schizophrenia syndromes group versus 47% of the non-schizophrenia group had a sick pension or were on long-term sick leave. Nine percent of the schizophrenia patients and 39% of the non-schizophrenia psychosis patients were rated as not being in need of treatment. Non-compliance of medication was present in one-third of those patients prescribed neuroleptic medication. Seven percent had never received neuroleptic medication, all of whom were rated as ill at the 5-year follow-up.


CONCLUSIONS
Incidence of treated first-episode psychosis is higher than has earlier been found, when exclusively outpatient treated individuals are also included. The social outcome is negative, even in the non-schizophrenia group. Non-compliance with medication and insufficient clinical follow-up may have worsened the results.
