We are not at a tipping point yet by any means. I think we've gone from this being heresy to being something that is now on the table and discussed. We have gone from probably no pilots to some very extensive pilots, for example, with primary care models in several jurisdictions involving millions of patients now. There are entire other models of care around hip and knee replacements, and hundreds of cataract surgeries, etc., are being done in this model, but unfortunately we're not quite at the tipping point yet.
This is a huge culture change for the health system. It is very profound and it requires a realignment of a lot of other parts of the health system: compensation, regulation, in some cases legislation, and in some cases insurance issues, depending on who you talk to.
I believe at least now a discussion is being held, but I think it is incredibly powerful, and the results we're seeing from those who have gone there are incredibly positive.
