Years ago, medical residents worked 100 hours or more per week with little rest and virtually no life outside the hospital. Today, with new rules in place, young doctors in training are not permitted to work more than 80 hours per week. The original goal was clear… well-rested doctors should provide better care. Those in charge of training future medical providers, however, feared cutting the training hours would lead to decreased experience for the next generation of doctors.
It appears as though the debate will continue as new research is coming to light that there might be no significant difference either way. Personally, I would prefer the surgeon working on me to be well-rested and highly experienced, but then I always want to have my cake and eat it too.
