Mental disorders among non-elderly nursing home residents.

Many Medicaid beneficiaries aged 22 to 64 with serious mental illness may be admitted to nursing facilities rather than psychiatric facilities as a result of Medicaid policies prohibiting coverage of inpatient psychiatric care in institutions of mental disease while requiring states to cover nursing facility care. Using nationwide Medicaid Analytic Extract claims from 2002, we found that nearly 16% of nursing home residents aged 22 to 64 had a diagnosed mental disorder, while 45.5% received antipsychotic medication, but these rates varied widely across states.
