When I say things like “controlling health-care costs is about treating sick people,” ACOs are the sort of thing I’m talking about. If they work as well as their advocates hope, costs could go down and quality could go up. If they don’t, it’s back to the drawing board. But most people don’t know much about them, even as their success or failure is ultimately the sort of thing that will determine whether the Medicare cuts can stick.

For more on ACOs, NPR has a good explainer. But if you’re the type of person who could do the explaining yourself, head over to the Incidental Economist, where they’re trying to crowdsource their way through the new regulations. Getting that done would be a real service.
