I don't have accurate numbers, but anecdotally, yes, they made more money. They had an incentive to do this, because they certainly had the time available to do it.
We're also tracking to see what impact it's had on the rest of their practice to make sure that no one else is at a disadvantage in the process of focusing on hips and knees.
I have to say that they've all become advocates of this, not only because they had more volume, but because it's better. They're now selling it to their colleagues and in fact saying that they've got to do this central triage approach with the teams because it's better for the patients. They become the advocates for others, who admittedly see that they can make more money with the current compensation system, which still has a volume incentive. But the case rate actually gives us the ability to give them an incentive across the continuum for access, quality, and cost-effectiveness, as opposed to only volume.
