General Internal Medicine (GIM) faces a burgeoning crisis in the United States, while patients with chronic illness confront a disintegrating health care system. Reimbursement that rewards using procedures and devices rather than thoughtful examination and management, plus onerous administrative burdens, are prompting physicians to pursue specialties other than GIM. This monograph promotes 9 principles supporting the concept of Coordinated Care--a strategy to sustain quality and enhance the attractiveness and viability of care delivered by highly trained General Internists who specialize in the longitudinal care of adult patients with acute and chronic illness. This approach supplements and extends the concept of the Advanced Medical Home set forth by the American College of Physicians. Specific components of Coordinated Care include clinical support, information management, and access and scheduling. Success of the model will require changes in the payment system that fairly reimburse physicians who provide leadership to teams that deliver high quality, coordinated care.
