In the mid-Atlantic region of the United States, an effort is under way to get insurers, providers, employers, and unions to cooperate in creating a system that can reduce total health care costs and premiums while achieving better outcomes. Our organization — the Institute for Healthcare Improvement — is assisting because we believe that this kind of regional initiative is the most promising way to move the U.S. to a system that achieves the “Triple Aim”:  better care for individuals, better health for populations, and a lower per capita cost.
