Earlier quoted context omitted.
To some extent the sleep deprivation is a weeding process/learning experience in and of itself. Being able to perform under stress/lack of sleep is a good quality in a doctor.
I am a 3rd year in medical school, and firmly believe that sleep deprivation is a terrible weeding process. If a doctor is sleep deprived I do not want them touching me with a ten foot pole. They make enough mistakes as it is! Sure you argue that they limit work hours, but I can tell you first hand that these limits are only paid lip service to, and I routinely see residents work 80+ (sometimes 90+) hours a week. Oh…
My SO is a medical resident. They really are placed in unstable situations (to use a math/physics term). They are required to work 80 hr/week. If they report working more than 80 hr/week they get into trouble for a duty hours violation and yelled at for being "inefficient". If they report less than 80 hr/week they get in trouble for being slackers (a.k.a. "unprofessional", actually that's a catch-all phrase for anything the speaker doesn't like). No serious thought seems to be given to increasing staff levels.
