I think it was quite strategic in how they picked their procedures because they elected to choose preference- and supply-sensitive conditions and probably in surgical specialties where they had the least resistance or surgical groups who were trying to advocate for additional funding there. So I think that's on that triad of the different factors as to how they pick them.
Also, for them I think it is assessing whether or not they have the informational capacity to be able to link all the cost data, the hospitalization data, and now the patient-reported outcomes data. That they're now bearing fruit from this and able to discuss effectiveness at a population level is truly outstanding. Although we don't hear any rumblings of expansion of this program I certainly think it's something we should take a hard look at.
