Interesting. I'm familiar with the concept and have been for decades, though I don't know that I'd previously seen actual data. A sixfold difference in mortality outcomes strikes me as pretty significant. Usually you'd want to see a caseload severity index when comparing data such as these, though I suspect for elective surgery that isn't a major contributing factor.

You're making me want to dig deeper into this area of study. Thanks.
