The use of a psychiatric register in predicting the outcome "revolving door patient". A nation-wide cohort of first time admitted psychiatric patients.
A nation-wide cohort of all first admitted patients to all Danish psychiatric institutions over a 1 year period and aged 15 years or more was followed for 10 years in the Danish psychiatric register. Revolving door patients were defined as patients with a minimum of four admissions and 1) no admission or discharge period lasting for more than 1/4 of the observation period or 2) at least four admissions over the first 1/4 of the observation period. The revolving door population comprised 1,397 patients with an incidence rate of 0.42 males and 0.32 females per 1,000. Forty-three point five percent belonged to the same diagnostic group at first and last diagnostic assessment ranging from 28.3% in "organic psychosis" to 57.6% in "neurosis". A multiple contingency analysis showed a number of variables at first admission significantly associated with the outcome "revolving door". Many were conditioned by others and the independent variables were "age group", "main diagnosis" and "sex". Patients aged 15-24 years constituted a high risk group among schizophrenics. The 15-24 age group was further at high risk among females with personality disorder or abuse and males with manic depressive and psychogenic psychosis. Living close to a psychiatric institution was in males associated with the outcome independently of age and diagnosis, in females it was restricted to personality disorder. Revolving door patients were significantly younger than others and more likely to suffer from schizophrenia or alcohol/substance abuse.
