There have been numerous efforts by payers and providers to improve patient access to high-functioning medical homes—an enhanced model of primary care that offers whole-person, comprehensive, ongoing, and coordinated patient- and familycentered care. Public payers, especially Medicaid, have been leaders in these efforts, with the hopes of preventing illness, reducing wasteful fragmentation, and averting the need for costly emergency department visits, hospitalizations, and institutionalizations. With the support of The Commonwealth Fund, the National Academy for State Health Policy (NASHP) has fostered these efforts through the Consortia to Advance Medical Homes for Medicaid and CHIP Participants.
