 Patients come to me delirious, sometimes unconscious, and they have no choice in where they end up. And the last thing I want my patient with a stroke or heart attack to do is start shopping around and looking at which would be the cheapest place to get their emergent procedure done. I want them to show up as close as possible, as quickly as possible. So I do worry that if we marry this with high-deductible health plans, as has been done in the past, that we're not going to solve the problem. Dr. Luke Messick from Brigham and Women's Hospital.
