Treating older persons with severe mental illness in the community: impact of an interdisciplinary geriatric mental health team.

Little information is available concerning community-based interventions to treat the growing number older persons with severe mental illness. This study examined treatment efficacy of a specialized interdisciplinary geriatric mental health team (mental health geriatric interdisciplinary teams or MHGITs) for 69 older clients with severe mental disorders. Depression, life satisfaction, health, and psychiatric and medical hospitalization data were gathered. A decrease in depressive symptoms and in psychiatric hospitalizations, and an increase in life satisfaction at 6 months were found. No change in health nor medical hospitalizations were reported. This study provides preliminary support for the feasibility and efficacy of a MGHIT approach in treating older community-dwelling adults with severe mental illnesses. Implications for social workers are discussed.
