After 10 hours on the job, a truck driver must pull off the road. After 16 hours, an airline pilot can no longer legally fly a plane. But after 24 hours or more on the job, with perhaps an hour nap somewhere along the line, a first-year medical resident can perform a surgical procedure, write a prescription, or insert a chest tube.
This introduction to a 2004 article in Focus Online, the newsletter from Harvard Medical, Dental, and Public Health Schools, says it all: we expect doctors to be superhuman.
When you stop and think about it, the expectation that medical residents, especially first-year interns, can, or should, perform incredibly complex procedures with minimal sleep is crazy. Medical researches agree—which is why hospital shifts of doctors-in-training have come under much scrutiny in recent years.
In 2003, the Accreditation Council for Graduate Medical Education (ACGME) created standards to restructure residents’ hours in order to combat fatigue, and the dangerous mistakes that accompany exhaustion. The council’s reforms limited residents’ hours to:
- No more than 80 hours a week
- No more than 6 work days a week, averaged over 4 weeks
- No more than 24 continuous hours of duty, except for another 6 hours of education or transfer of care In-house call no more often than every third night
- No less than 10 hours of rest between duty periods
These changes were meant to benefit not only residents, but also patients: an exhausted doctor is a careless doctor. But for all of the Council’s good intentions, studies show that the ACGME reforms don’t go far enough—residents need more of a break if they are to maximize their effectiveness and ensure the safety of their patients.
How do we know? Last year, two studies from Kevin G. Volpp, MD, PhD, from the Center for Health Equity Research and Promotion, VA Hospital in Philadelphia, Pennsylvania looked at whether the first four years of the ACGME guidelines had resulted in a meaningful decline in patient mortality—in other words, if the guidelines had saved lines by keeping doctors alert and rested.
