Race, gender, and health care service utilization and costs among Medicare elderly with psychiatric diagnoses.

OBJECTIVE: To investigate race and gender differences in health care service utilization and costs among the Medicare elderly with psychiatric diagnoses.
METHODS: The authors employ a 5% sample of Medicare beneficiaries from Tennessee (N = 33,680), and among those with a psychiatric diagnosis (n = 5,339), they examine health care service utilization and costs by race and gender.
RESULTS: African Americans had significantly higher rates of diagnosis for dementia, organic psychosis, and schizophrenia, whereas Whites had significantly higher rates for mood and anxiety disorders. White and African American men have higher rates of utilization of emergency and inpatient services and lower rates of outpatient utilization compared to White women and African American women. African American men have significantly higher health care costs. DISCUSSION: The findings suggest that race and gender interact to influence service utilization and preventive care, thereby driving up costs of care, for elderly persons with psychiatric diagnoses.
