The transition from ACO 1.0 and ACO 2.0 for most organizations will be necessary but challenging. In ACO 2.0, risks will be greater requiring advanced actuarial capabilities and meticulous attention to care coordination. Relationships between and among physicians will change as risk is shared among tighter networks of high-performing practitioners in the acute and post-acute settings around patient populations covered in bundled payment programs. The scope of regulatory oversight will widen, publicly accessible data about the performance of the ACO will be readily available and the effectiveness of patient engagement magnified.
In this issue brief, the authors provide lessons learned from successful ACO 1.0 leaders and three considerations that can assist in optimizing shared savings.
