Measuring the medical home infrastructure in large medical groups

The patient-centered medical home is taking center stage in discussions of primary care innovation as a new delivery model that provides comprehensive, coordinated care across the lifespan. Although the medical home is widely discussed by policymakers, payers, and other stakeholders, the extent to which physician practices have the infrastructure in place to function as medical homes is not known. Using data from the 2006-07 National Study of Physician Organizations, we examine the extent of adoption of medical home infrastructure components among large primary care and multispecialty medical groups and their association with medical group size and ownership.
