A new health report released by the Primary Care Collaborative (PCPCC) documents the adoption of the patient-centered medical home model (PCMH) in the U.S. as nothing short of impressive."The number of medical home providers has grown to the tens of thousands, serving millions of Americans," reads the Benefits of Implementing the Primary Care Patient-Centered Medical Home: A Review of Cost and Quality Results, 2012 "Momentum for the model is rapidly increasing with public and private sector investment.”Complementary to the PCPCC’s 2010 study on PCMHs, the current review summarizes model initiatives promoted over the past two years, including cost and quality outcomes. One such PCMH initiative launched in early 2011 by CareFirst — a mid-Atlantic private insurance carrier — garnered nearly $40 million in savings for the Washington metropolitan area during that fiscal year. A 4.2 percent reduction in patient overall healthcare costs among 60 percent of the practices utilizing the model for six months or more was also facilitated by the initiative.
