The document discusses Accountable Care Organizations (ACOs) created by the Affordable Care Act. ACOs allow groups of doctors, hospitals, and other providers to share responsibility for the cost and quality of care received by their patients. If ACOs meet quality benchmarks and reduce costs, they receive a share of the savings from insurers. The document outlines key features of ACOs such as local accountability, shared savings based on quality and cost measures, and a minimum of a 3-year contract period with Medicare.
