A Milbank Memorial Fund report’s writers conclude that ”Medicaid ACOs have the potential not only to align payment and care delivery incentives to promote high-quality, well-coordinated care, but also to improve population health within their enrolled population and beyond. States, in conjunction with county governments and commercial payers, can help ensure that Medicaid ACOs play an important role in improving health outcomes across the life course by (1) requiring ACOs to incorporate population health–focused design and governance structures, patient services, metrics, and information-sharing systems; and (2) focusing on building strategic partnerships between ACOs and other population health–oriented entities. States that incorporate population health components in Medicaid delivery system reforms will experience health improvements and cost reductions—but these improvements will only reach the height of their potential if states coordinate these initiatives with other agencies, insurers, and providers.”
