As others have pointed out, the issue is not so clear cut.
1. There is no question that the BOM should "police" the system and should remove the license / limit privileges / set restrictions on physicians who clearly endanger patients.
2. Giving the BOM wide discretion is complicated, as if they remove your license you are essentially out of business. It's reportable to all the other states, who are likely to follow suit. One could imagine a story of the chairperson of a BOM simply removing the license of a competitor, or just someone that they don't like. Even if it was appealed and successful, losing you license for a short period of time will cost you your job, all of your patients, etc.
3. Is the BOM really staffed to review all these cases? Getting to the bottom of any story like this is complicated. Hosiptals and physicians are unlikely to hand over records willingly, knowing that these records could also be used in a medmal suit. Hence, you'll have lawyers, subpeonas, quashing, the whole nine yards -- very expensive and time consuming.
4. Should the BOM take the primary role of punishment, or remediation? An interesting question. The drunk MD who kills someone by failing to intubate, for example. certainly, they are going to be sued by the family and lose (assuming the family knows the whole story). Should the doc be forever prohibited from working? Or, if they get treated and are EtOH free, then should they get to work again? What if they just have a high EtOH level but no patient harm happens? Is that really any different? It's not so clear, at least to me.
5. What should happen to physicians during the investigation? Should they get to continue working? If not, their practices could go bankrupt. If so, they could put someone else in harm's way.
6. Where does this stop? if you make an error as a resident, is that it for your career?
There is no question that in the article, there are some crazy seeming situations -- docs who expose themselves / abuse children continuing to practice as child psychiatrists. This is completely crazy. Docs with clear evidence of unacceptable behavior need to be stopped.
