Utilization of mental health services by the aging.

A descriptive study of persons 55 years of age and older who were newly admitted (60 cases) or in ongoing treatment (30 cases) in a mental health center was done as an outgrowth of a utilization review study. The total population of 461 was studied from July 1, 1977, to June 30, 1978. A chart review of 90 cases was performed. The newly admitted subsample was married, was diagnosed as depressed, and had a broad range of dispositions into various treatment modalities. The chronic subsample was single, diagnosed as schizophrenic, and in treatment in a single community-support unit. These differences were statistically significant at the P<.01, P<.001, and P<.001 levels, respectively. Although the newly admitted subsample had no previous contact with psychiatric services, 44 of the 60 patients (73 percent) were on psychoactive medication prescribed by nonpsychiatric physicians. Implications for the training of general medical practitioners and mental health center staff, and the need for ongoing assessment of patients in community support units are discussed, as well as the significant risk to patients from potentially harmful drug interactions.
