Last month, a superb study by the Michigan Bariatric Surgery Collaborative showed that the more skilled surgeons were, the better were their outcomes.
Surgeons submitted a video of their choice depicting their performance of a laparoscopic gastric bypass. Since it was self-selected, it was presumably their best work. At least 10 of their peers, blinded as to the name of the surgeon, rated skills on the video which had been edited to include only the key portions of the case.
Surgeons in the lowest quartile of ratings for surgical skill had significantly more postoperative complications, readmissions, reoperations, and deaths.
A New York Times article about the paper features a couple of short video clips—one from a not-so-skilled and one from a very skilled surgeon. The differences are obvious and dramatic.
According to the discussion section of the paper, the Michigan bariatric surgeons are now watching each other operate and will soon be receiving anonymous feedback about their technique from their peers.
It is not clear whether this will improve the skills of the lower-rated surgeons or have any effect on outcomes.
Many people rightfully praised the research. Some suggested that all surgeons should be scrutinized in this same fashion.
I agree that the study was well-done and shows that technically better surgeons have better outcomes.
But there are some problems with generalizing this to all surgeons.
