We've discussed ACO's for some time, both here, and on Angry Bear. There is still a lot of nervousness regarding their implementation based on their pilot project results.
Wyoming however, is coming up with a new, novel concept
Rather than allow hospitals and providers to form smaller, perhaps fragmented ACO systems, they are proposing a state-wide ACO, with adoption, and implementation of the concept throughout the state.
Very interesting take on the ACO concept, and perhaps a great idea. More at the link.
