Fourteen hospital systems from across the United States in November announced plans to invest more than $700 million in community-based efforts to tackle the economic and environmental forces that contribute to disparities in health outcomes. The national campaign marks the first time that a number of large health systems have collectively pledged to make such impact investments. The effort has been spearheaded by the Healthcare Anchor Network, the collaborative of hospitals and health care systems started in 2017 to help members learn about challenges, innovations, and best practices from peer institutions.
