The authors describe the ethical considerations underlying the inclusion of mental health services into a prioritized health care system. The Oregon Health Plan is a process for defining and delivering basic health services to an entire state. As the plan was developed, the mental health community needed to decide whether or not to participate in the process and, if so, how. Lengthy discussions among mental health consumers, family members, and providers led to a strategy that emphasized the integration of mental (...) health and chemical dependency services into a comprehensive and universal health care program. This approach appears to have achieved relative parity for mental health. (shrink)
