The ACO Surprise: 30 million Americans are enrolled in one

"Successful ACOs won’t just siphon patients away from traditional providers. They will change the rules of the game."

The healthcare world has only gotten serious about accountable care organizations in the past two years, but it is already clear that they are well positioned to provide a serious competitive threat to traditional fee-for-service medicine. In "The ACO Surprise", Oliver & Wyman's analysis finds that 25 to 31 million Americans already receive their care through ACOs—and roughly 45 percent of the population live in regions served by at least one ACO. While relatively few organizations have achieved the full potential of the model, the top performers are already generating savings and delivering improved care.
