See also T.P. Wright's Law governing the rate of process improvement with the volume of production. This focuses on labour input, not quality output, but is on the order of 10-15% with each doubling of output.

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.
