Medical experts are calling for resident working hour restrictions to prevent medical errors from medical resident fatigue and lack of supervision. They called for sweeping changes in the design, supervision and financing of US hospital residency programs to protect both patients and medical residents in training from serious, preventable medical errors, and end dangerously long work hours.
There is no justification for maintaining unsafe work hours, other than they save hospitals substantial sums of money that would need to then be spent to pay for more physicians or physician assistants. This could come to tens of millions of dollars every year that they don't want to pay.
