The national campaign marks the first time that a number of large health systems—such as RWJBarnabas Health in New Jersey, UMass Memorial Health Care in Massachusetts, Advocate Aurora Health in Wisconsin, and Intermountain Healthcare in Utah—have collectively pledged to make such impact investments. Kaiser Permanente plans to make one of the largest, at $200 million, to help finance affordable housing in Northern California and elsewhere. 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.
