That's fair, and yes, there are other layers of physician-led peer discipline. The difference, of course, is that other than the licensing board these extra layers are not public. The lack of public disclosure may have good reasons behind it, but the end result is a fairly opaque process for our patients and the perception that all we do is cover up each others' mistakes. It also facilitates the phenomenon of bad physicians traveling from one location to another, along the lines of child abusing priests. I'm continually amazed at how many hoops drug or alcohol abusing physicians are made to jump through to keep their license (and rightly so, of course), but how few requirements the boards impose on negligent physicians.
The starting point of this discussion was the off-handed remark by another poster that "all malpractice attorneys are scum" or something along those lines. I continue to believe that they serve an important role, and are a key element for patients to "find out what happened" when something goes wrong. Given how many board and hospital actions are precipitated by malpractice actions, one could almost argue that are necessary to a functioning supervision system of physicians.
