This is Scientific American’s 60-Second Science. I’m Steve Mirsky. Got a minute?

Over the years regulations have developed to limit the hours of hospital interns¹ and residents, because someone putting in a 100-hour workweek might not be at their best when deciding which medication to prescribe or when inserting a Foley catheter. But doctors who have finished their training don’t face any restrictions² in their hours. Now The New England Journal of Medicine argues in an editorial that sleep-deprived physicians set to perform elective surgery should have to get the informed consent of the patient.

Sleep deprivation³ can impair⁴ motor skills as much as alcohol intoxication⁵ can. The editorial cites a 2009 study in the Journal of the American Medical Association that found an increase in the risk for complications in patients who had elective surgery performed by surgeons who’d had the chance for less six hours of sleep during a previous on-call night.

The editorial’s authors note that such consent represents a new responsibility for patients in making decisions about their care. It could damage the patient-doctor relationship. But, they say, "This shift may be necessary until institutions take the responsibility for ensuring that patients rarely face such dilemmas⁶."

Thanks for the minute. For Scientific American’s 60-Second Science, I’m Steve Mirsky.
