Discussions of health care reform emphasize the need for coordinated care, and evidence supports the effectiveness of medical home and integrated delivery system models. However, mental health often is left out of the discussion. Early intervention approaches for children and adolescents in primary care are important given the increased rates of detection of mental illness in youth. Most adults also receive treatment for mental illness from nonspecialists, underscoring the role for mental health in medical home models. Flexible models for coordinated care are needed for people with serious mental illness, who have high rates of comorbid medical problems. Programs implemented in the New York State public mental health system are examples of efforts to better coordinate medical and mental health services.
