Total Health is a vision for the future and a strategy to prevent preventable disease, save lives, and make health care more affordable. Total Health means health of mind (behavior health) and health of body (physical health). To achieve Total Health we need healthy people in healthy communities. A behavior medicine specialist is a psychologist who works in the medical home with the primary care physician instead of in the Mental Health Department with a psychiatrist. The key to achieving Total Health will be to transform our current health care system from a focus on treating disease to a focus on preventing disease. This transformation will require complex behavior change interventions and services not usually provided in the medical home. The behavior medicine specialist will bring the knowledge and experience used to treat mental illness into the medical home to help the primary care physician improve the care of all patients in the medical home. The behavior medicine specialist will help improve outcomes in synergy with the primary care physician by universal screening of high-risk diseases, stepped care protocols, and efficient use of all resources available to care for patients in the medical home (health education classes, wellness coaches, and online social networking lifestyle management programs). These interventions should increase patient satisfaction, increase access to specialty care (psychiatry), and help us achieve Total Health.
