To compare health care utilization and payments between ‐recognized patient‐centered medical home () practices and practices without such recognition.
Medicare Part A and B claims files from July 1, 2007 to June 30, 2010, 2009 Census, 2007 Health Resources and Services Administration and Utilization file, Medicare's Enrollment Data Base, and the 2005 American Medical Association Physician Workforce file.
This study used a longitudinal, nonexperimental design. Three annual observations (July 1, 2008–June 30, 2010) were available for each practice. We compared selected outcomes between practices with and those without recognition.
Individual Medicare fee‐for‐service () beneficiaries and their claims and utilization data were assigned to or comparison practices based on where they received the plurality of evaluation and management services between July 1, 2007 and June 30, 2008.
Relative to the comparison group, total Medicare payments, acute care payments, and the number of emergency room visits declined after practices received recognition. The decline was larger for practices with sicker than average patients, primary care practices, and solo practices.
This study provides additional evidence about the potential of the model for reducing health care utilization and the cost of care.
