The value of health care — defined as the health outcomes achieved relative to the costs invested — is an increasing concern in the United States. Health care spending is expected to accelerate over the next 5 years, reaching 20% of the U.S. gross domestic product by 2025. Quality of care and health outcomes remain sub-optimal. While environmental, social, and behavioral factors are the primary determinants of poor population health status and health outcomes in the U.S.,4 significant opportunities remain to improve the value of health care and the health care delivery system. Moreover, the health care system has an obligation to play a meaningful role in helping to overcome the effects of these external factors.
