Heading in for elective surgery can be a nerve-racking experience. People tend to worry about who's taking care of the kids, how much work they'll miss or how much pain and discomfort the operation will bring on. They don't generally stress over whether their surgeons have had enough sleep.
But some doctors believe patients should think about how much sleep their surgeon got the night before, and should be told if the surgeon may be sleep-deprived so they can decide whether to go through with the surgery that day or reschedule it.
"We have data that show that sleep deprivation affects clinical performance, and we also have data that show that patients want to be informed if their surgeon didn't get enough sleep, so it's become a patient advocacy and safety issue," said Dr. Michael Nurok, lead author of an article on sleep deprivation and informed consent in the latest issue of The New England Journal of Medicine.
Nurok, who is also an anesthesiologist at the Hospital for Special Surgery in New York, alluded to a past study published in the Journal of the American Medical Association that highlighted some of the risks posed by surgeons who operate in a sleep-deprived state.
"When looking at procedures done when a surgeon has less than six hours of sleep, there's an increased risk of bleeding and organ damage," he said.
Nurok said he hopes to draw attention to the need for patients, doctors and medical centers to become more aware of the hazards posed by sleep deprivation. He and his co-authors believe that medical institutions should prohibit surgeons who have been on emergency call all night from scheduling elective procedures the next day, and institutions should also make it easier to reschedule surgeries.
He acknowledged, however, that there are a number of barriers that could make it difficult to enforce regulations against surgeons operating on too little sleep, among them the "culture of surgery" and the current demands of the health care system.
"The culture of surgery [meant] to forge ahead and not complain about things like lack of sleep," said Dr. David Cronin, an associate professor at the Medical College of Wisconsin in Milwaukee. Complaining about lack of sleep "was looked down upon as ... a sign of weakness."
In general, people don't always judge their own level of fatigue very well, and surgeons are no different.
"As with everybody, they could be impaired and not even be aware of it," said Nurok.
But other surgeons believe the decision to disclose should be up to the physicians. They told ABC News they've been in several situations where they've been too tired to perform surgery and opted out, offering the patient the chance to reschedule or have another surgeon operate.
"I believe the vast majority of surgeons want the best for their patients and are aware enough of their own abilities to make this call," said Dr. John Byrne, chairman of the department of cardiac surgery at Vanderbilt Heart and Vascular Institute in Nashville, Tenn.
