Innovations in Integrated Dual Diagnosis Treatment in Public Managed Care: The Choate Dual Diagnosis Case Rate Program

This article describes the implementation and preliminary evaluation of a dual diagnosis case rate program developed as a collaborative experiment between a public managed Medicaid organization (MHMA) and a specialized integrated dual diagnosis provider (Choate) with a vertically integrated, managed-care oriented system of care. The case rate program applied to dually-diagnosed inpatient referrals for a period of 65 days. On admission, 68% of the patients had little insight, motivation and compliance regarding addiction or psychiatric management. Nonetheless, 56% maintained sobriety for 65 days, and 49% of these were still sober at 95-day follow up.
