Hospitalization patterns in schizophrenia. A 13-year follow-up.
All first admitted patients in 1972 from a catchment area of 582,000 inhabitants aged 15 years or more who were diagnosed as schizophrenic at least once from 1972 until September 1983 (n = 53) were followed-up on average 13 years after first admission. About 20% of the cohort was hospitalized on any given day throughout the length of the follow-up period. The duration of hospitalization decreased from a mean of 8.2 months for the first admission to 1.7 months for the tenth or later admission. The readmission risk increased as a function of the number of previous admissions. Patients with income from occupation or from grants for education had shorter duration of first in-patient period. If the patients were diagnosed as schizophrenics already during the first hospitalization the risk for prolonged duration of the first in-patient period was increased but the readmission risk diminished. Furthermore, readmission risk after the first discharge was diminished by own income and by out-patient treatment and increased by low social status. High proportion of follow-up time in hospital (greater than or equal to 30%) was correlated to affective flattening present at first admission. Of the cohorts' total number of admissions (n = 493) 12% were involuntary. Involuntary admissions were more frequent in the first half of the follow-up period and were correlated to a previous involuntary admission.
