The model I would suggest is endorsing the hospitals to create innovation teams of some sort. They would, for example, bring forward a proposal that they would see savings, let's say, of 10%, in a certain set of procedures. They would then communicate that to an office that says, “We have this plan. If we actually achieve that, let us keep that 10% and we'll use that for further innovations within the system. If we don't achieve it, then we won't be able to keep it.”
Basically, you could propose an innovation, register it, and if you do have the savings you get to keep them in your budget and roll them forward. You would turn the hospitals into environments that would look for innovation because they would then have more resources to address the other pains that many of them are fighting.
