Confound it all

Yes, it is possible to lose your medical license after one patient dies.

Can I just say that I’m a little horrified at the callousness of the people on the internet who have suggested that “one patient“  dying is too little for someone to get their license revoked? Although, this being the internet I shouldn’t be that surprised in retrospect.

(Context: I have read several claims that, by making Watson in CBS’s Elementary a former surgeon who had her license revoked after one itty-bitty person died under the knife, not only had they ruined the character but that such a thing is improbable.)

Losing your licence is a matter of malpractice, so if one patient dies and if they conclude that you were at fault when they reviewed the incident, then yes, you get your licence revoked. 

Actually, not even one patient has to die.
