However, I think hand in hand with this you need to map outcomes data, especially for invasive procedures. Often, the reason to go to a "Big Hospital" say UCSF instead of Podunk Community Hospital is that there is often a big disparity in skill between a UCSF faculty surgeon vs. others. Or, even between different hospitals.

I'm not sure how to do this - hospitals like to hide adverse outcomes from the public, but it's really information in the public interest. Ideally you'd want some sort of index that weighs complication rates (something unexpected happening), outcome/effect measures (procedure did what it was supposed to do), with price.
