Background: In 2017, the John A. Hartford Foundation partnered with the Institute for Health Care Improvement, American Hospital Association, and Catholic Health Care Organization to define the 4Ms framework to improve quality of care and health outcomes for older adults. The senior leadership of one of the largest integrated healthcare organizations (HCO) in the country recognized the relevance of these recommendations to the aging demographic of the United States.
