Well, I think we have pretty good evidence from a number of places and a number of different countries that a fee-for-service way of funding health professionals does not encourage interdisciplinary care--and it does not lead to the best possible care, either.
I think that's a huge change, though, because we have a tradition of funding most medical practitioners, although certainly not all of them, and not all of them in primary care. As we move to true primary care as opposed to family practice, I think we're seeing a move away from fee-for-service and other means of remuneration that support well all the health professionals.
I think that's a fundamental change that is needed in order to move us more universally to that.
