Evaluating the Formation and Performance of Accountable Care Organizations: Focus on High-Need, High-Cost Populations, Year 5


Evaluating the formation of accountable care organizations (ACOs) is essential to determining whether this model of integrated care delivery can achieve its promise of providing high-quality, population-based care at lower cost. In the previous phase of this project, the Dartmouth team conducted a first-of-its-kind national survey of more than 170 ACOs, identified ACO market characteristics, and described how these organizations manage high-risk patients and distribute shared savings. In the next phase, the team will continue to advance the state of knowledge about ACOs. Focusing on the treatment and management of high-need, high-cost patients, the team will field a follow-up survey of ACOs and conduct additional analysis to assess: 1) ACOs’ management of care transitions for these patients; 2) the degree to which Medicare ACOs are pursuing Medicaid contracts, and how these contracts affect care for dually eligible beneficiaries; 3) whether ACOs are engaging patients in care decisions and treatment plans; and 4) the likelihood of ACOs forming in areas with a concentration of high-need residents.
