That's a good idea.
Maybe, but the best surgeons get the hardest cases, which have less desirable results.
The best surgeons can take on the toughest patients, and considering what they are up against do very well, but not have that reflected in these numbers.
The 'cherry pickers' who only do the easiest cases will have the best survival rates.
Without a difficulty scale, or an explanation of the types of cases, the numbers could be incredibly misleading.
