The decisive incident that forced a decision that a particular individual could no longer remain in the community and must be admitted to a mental hospital was studied from the point of view of the person making this decision. Descriptive data on 100 schizophrenic patients were analyzed to determine whether prompt medical and social work collaboration at the point of admission might prevent hospitalization.Fifty-three patients actually committed or threatened to commit a dangerous act. Thirty-eight patients exhibited behavior that was socially unacceptable. Nine patients were perceived as needing treatment for illness. Only 4 patients requested hospitalization.Demographic and social characteristics were not statistiscally significant in relation to the type of "last straw." As the number of hospitalizations mounted, the crucial event tended to progress from a mild behavioral change to threatening behavior, to actual assault. The final events were "family and community specific"and depended on particular standards and sensitivities.Since many "last straws" are extreme and the family and the community have reached their limit of tolerance, the number of hospital admissions can be reduced only by extending care to the patient before his removal from the community is the only alternative.Abstract Teaser
