Near the end of the book Why We Sleep, the author specifically talked about this. The lack of sleep contribute to 170% likely more cause an error during surgery. Scary to ponder... He mentioned the guy that started the residency program, Halstead, in John Hopkin turned out to be a cocaine addict. He stressed that a doctor needs to work all the time. No one knew about his drug addiction until he had passed away. He even tried to get rid of the addiction by checking into a rehab up north but came away in addition to the cocaine addiction but also a morphine addiction as well.
