Patterns and correlates of psychiatric hospitalization in a nationwide sample

Summary A nationwide random sample of psychiatric patients (n = 832) admitted for hospitalization in Israel in 1980 was followed up until the end of 1984 regarding their hospitalization patterns. Information about hospitalizations as well as demographic and diagnostic data were obtained from the Israel Central Psychiatric Case Register. Two main contrasting patterns of hospitalization emerged. One pattern consisted of a single short hospitalization during the entire follow-up period. This pattern was found among more than 50% of those patients for whom this hospitalization was the first in their life. The second pattern characterized the patients who accumulated long periods of inpatient stay, that is, at least one year during the follow-up period. These are the new chronic patients (about 30% of the total sample). About one third of these new chronic patients (8.2% of the total sample) accumulated their long stay through one continuous hospitalization, thus resembling the old chronic patients; two-thirds accumulated their long stay over several hospitalizations. Each patient has a fairly constant pattern of hospitalization, regarding the length of stay in hospital and out of hospital.
