But, if I were a patient, or a fellow doctor, what really matters? Everything has tradeoffs....no one can be the best in the world at more than a few things. What would the number 1 surgeon in the entire world (the best surgeon) have as a characteristic?
The answer is : results. The best surgeon in the world would choose the best possible intervention for each patient (including not operating at all), and then would carry out that intervention with perfect technical skill. No more, no less. Each patient would have the best odds for gaining the most quality years of life gained.
The best surgeon might not teach anyone, or be a terrible teacher. Yet, I argue, he would still be the best.
The best surgeon might be a complete *******, or a total pushover. But as long as he or she got the staff to do their jobs, such annoying personality traits don't change reality.
Patients might hate the surgeons' beside manner....doesn't change anything, this surgeon is still the best.
Hospital administrators, medical boards, the entire world might hate this surgeon....but the reality is what it is. No other definition of "best" fits the bill.
I'm trying to create an extreme case here (obviously the best surgeon wouldn't stay the best for long if he couldn't get access to top notch staff and top notch operating equipment) to show that this question has a clear answer.
And one final comment : if such a person exists, statistics might not show it. You would have to have perfect knowledge (aka viewpoint of God) to actually determine who the "best surgeon" by my definition actually is.
I'm not meaning to be inflamatory : but the whole topic reminds me of various wishy-washy stuff in a recent ethics class. If this question was rephrased : "What makes an excellent golfer?" the answer is pretty cut and dried (hits the ball as few times as possible). The person that touches the ball the least is the best. A surgeon's job is to repair patients to extend their conscious time on earth. The surgeon that averages the longest times is the best (assuming identical patients). End of story.
