Accountable care organizations and antitrust: restructuring the health care market.
"Accountable care organizations represent a major experiment in health care delivery and financing. Two major questions remain unanswered. How can clinical integration be encouraged while preventing excessive antitrust risk; and how can cost shifting from federal to private payers be mitigated? Achieving the appropriate balance between market power and efficiencies is critical to that experiment. A significant challenge will be in those instances for which there is evidence of increased prices due to market power of large ACOs but also evidence of increased efficiencies in care coordination and patient experience with their care. Whether the relevant parties involved will regard this type of outcome as acceptable remains to be seen."
