This study evaluated the impact of a patient-centered medical home (PCMH) pilot on utilization, costs, and quality and assessed variation in PCMH components. Data included the New Hampshire Comprehensive Healthcare Information System and Medical Home Index (MHI) scores for 9 pilot sites. A quasi-experimental, difference-in-difference model with propensity score-matched comparison group was employed. MHI scores were collected in late 2011. There were no statistically significant findings for utilization, cost, or quality in the expected direction. MHI scores suggest variation in type and level of implemented features. Understanding site-specific PCMH components and targeted change enacted by PCMHs is critical for future evaluation.Keywords commercial insurance; delivery system reform; patient-centered medical home; primary careHealth care organizations are increasingly looking for ways to address rising health care costs, inconsistent quality, and fragmentation in the US health care system. The predominant payment system, fee-for-service, rewards volume over value (Aaron & Ginsburg, 2009;Goroll & Schoenbaum, 2012;Miller, 2009), does not incentivize coordination between providers or care settings (Miller, 2009), and does not invest in health information technology, chronic condition management, or broader practice and systemwide improvements (Abrams et al., 2011;Barr, 2008;Ginsburg et al., 2008). As the number of people with multiple chronic conditions grows, the task of providing and coordinating care becomes increasingly complex (Matlow et al., 2006). Communication errors are common, information sharing is in-sufficient, and handoffs between individual physicians, hospitals, and other health care providers are poorly coordinated (Institute of Medicine, 2001;Matlow et al., 2006).The patient-centered medical home (PCMH) model aims to improve quality and reduce costs by treating the patient as a whole person, improving care coordination, and providing advanced team-based primary care and population health management supported by health

Recent findings from nonintegrated primary care settings on the impact of the PCMH on utilization, costs, and quality show moderate improvements. A study by Friedberg et al. (2014) evaluated the impact of the Southeast Pennsylvania Chronic Care Initiative, a multipayer PCMH pilot guided by NCQA recognition. The authors reported improvement in one diabetes process measure (nephropathy monitoring) for PCMH sites relative to non-PCMH sites, but no statistically significant improvements in utilization or cost measures by PCMH sites relative to non-PCMH sites over 3 years (Friedberg et al., 2014). A study of the Rhode Island Chronic Care Sustainability Initiative showed lower rates of ambulatory care-sensitive emergency department (...
