In the pre-managed-care era, within our recent memory, both private and public insurance offered strong incentives for providing inpatient care. Coverage was generous for those who crossed the threshold from outpatient to inpatient status, and extremely stingy for any day, outpatient, or residential care. It's not surprising that even weak incentives through managed care to move patients out of hospital beds would reduce costs. These incentives should provide greater access to cost-efficient and effective alternative approaches, especially for patients with severe and persistent mental illness with a dual diagnoses of substance abuse.
