PCMH Evidence

Patient-Centered Medical Homes are driving some of the most important reforms in health care delivery today. A growing body of scientific evidence shows that PCMHs are saving money by reducing hospital and emergency department visits, reducing health disparities, and improving patient outcomes. The evidence we present here outlines how the medical home inspires quality in care, cultivates more engaging patient relationships, and captures savings through expanded access and delivery options that align patient preferences with payer and provider capabilities.

NCQA-Recognized PCMH Studies

Additional PCMH Evidence


NCQA Patient-Centered Medical Homes Cut Growth in Medicare Emergency Department Use: Medicare Claims & Enrollment Data

NCQA PCMHs cut the growth in outpatient ED visits by 11% over non-PCMHs for Medicare patients. The reduction was in visits for both ambulatory-care-sensitive and non–ambulatory-care-sensitive conditions, suggesting that steps taken by practices to attain patient-centered medical home recognition may decrease some of the demand for outpatient ED care.

NCQA Patient-Centered Medical Homes Lower Total Cost of Care for Medicare Fee-for-Service Beneficiaries: Medicare Claims & Enrollment Data

Medicare fee-for-service beneficiaries receiving care in NCQA-recognized PCMH practices had lower total annual Medicare spending than beneficiaries in comparison practices. Medical home implementation resulted in lower payments to acute care hospitals and fewer emergency department visits. The declines were larger for practices with sicker than average patients, primary care practices, and solo practices.

Patient-Centered Medical Home Initiatives Expanded Fourfold from 2009–13
Programs that promote Patient-Centered Medical Home transformation with payment reform incentives continue to rapidly expand across the United States. Private and public payer initiatives together have grown from 18 states in 2009 to 44 states in 2013, and now cover almost 21 million patients. These heterogeneous initiatives overall are becoming larger, paying higher fees, and engaging in more risk sharing with practices.

Patient-Centered Medical Home Initiatives Produce 6 to 1 Return on Investment: UnitedHealth Center for Health Reform & Modernization

An actuarial evaluation of four medical home programs in Arizona, Colorado, Ohio, and Rhode Island, based on operation between 2009 and 2012 for 40,000 members, found average gross savings of 7.4% of medical costs compared to traditional primary care practices. Every dollar invested in care coordination activities produced $6 in savings in the third year (a return on investment of approximately 6 to 1). Including the cost of the intervention, the programs saved approximately 6.2% of medical costs on average.
