In 2007, the Joint Principles of the Patient-Centered Medical Home were released by the four primary care physician societies—the American Academy of Family Physicians (AAFP), the American Academy of Pediatrics (AAP), the American College of Physicians (ACP), and the American Osteopathic Association (AOA)—and have since been endorsed by 19 additional physician organizations, including the American Medical Association, as well as the Patient-Centered Primary Care Collaborative (PCPCC), a multi-stakeholder coalition with a mission to develop and advance the patient-centered medical home. Following the release of these Joint Principles, the PCMH concept has become a fast-growing model of primary care redesign across the country, with many demonstration and pilot projects underway or in development. As a result of the proliferation of test* projects and the overall growing interest in the PCMH concept, there are now multiple entities developing or offering medical home recognition or accreditation programs. The primary care physician societies have long supported the need for robust recognition and/or accreditation programs to help assess whether a given practice is delivering care based on the PCMH model. Therefore, to assist with the development and use of these programs, the AAFP, AAP, ACP, and AOA offer these “Guidelines for Patient-Centered Medical Home Recognition and Accreditation Programs.”
