> Patient outcome and contentedness compared to others with similar indications.

and how you would achieve it? "similar indications" would be coming from doctor that you are trying to rate

rating "contentedness" gets you doctors prescribing useless medications to keep patients happy

expert surgeons have often bad survival rates as they get complicated cases, and trying to rate how complicated cases are to compare two experts would be nightmare as bad as rating doctors - so you only replace one hard problem with another as hard problem
