df, I believe there is a workshop happening up in LA in the next few months. It's not much of a major discussion here in southern cal. at ths time. Dr. Wilson out of Costa Mesa is one of the speakers and a very good presenter. ACOs provide a mechanism to transition from paying for volume and intensity to paying for value. most of our discussion has been about wether they are compatible with a range of other payment reforms to improve quality, such as medical homes and bundled payments and can they lead to quality improvemnets. Alot of pros and cons, as with any new implementation. I think the upcoming conference will address a lot of key points and questions.
