Jennifer Rodney, MD, a fifth-year resident physician in the department of otorhinolaryngology at the University of Oklahoma Health Sciences Center in Oklahoma City, never really understood the work hours limitation on first-year interns. Under rules put in place in 2011, first-years were limited to 16-hour shifts, while other physicians could still work 24-hour shifts.

August 2017Under revised rules that went into effect July 1, 2017, that limitation was lifted and all residents can work the same number of hours.
Good, said Dr. Rodney.
“It didn’t make a whole lot of sense to have the limitation and have them have to clock out at a certain time each day,” she said. “And when July 1 hit this year, all of a sudden that rule doesn’t apply, and they have to stay until the end of the day when the patient is done being seen. That’s the thing about medicine. … You can’t go home at a certain hour. You go home when your patients are taken care of. It was just unrealistic to treat an intern differently than the rest of the residents, because they’re going to be out of that position the next year anyway.”
In the long run, the Accreditation Council for Graduate Medical Education (ACGME) agreed. Rowen Zetterman, MD, chair of ACGME’s board, said that when the hours limit was set in 2011, it was with the understanding that the threshold would be reviewed after five years. A similar review of the new rules will take place in 2022, or sooner if new evidence warrants it.
“We heard from residents who were in the middle of an operative case,” Dr. Zetterman said. “A patient that had admitted in the previous 16 hours needed an emergency operation … and 16 hours came in the middle of the case, and they were told to go home. That was clearly an issue.”
The ACGME reviewed more than 1,000 studies and, in March 2016, held a two-day conference to which it invited 60 medical groups and organizations “to testify to us about what should be done in the learning/working environment,” Dr. Zetterman said. “Of all the 60 medical organizations that were there, the majority said we needed to return to 24 hours for first-year residents,” he added. “Most of them cited the impact it had on team-based care.”

Continuity of Care
Otolaryngologist Nilesh Vasan, MD, an associate professor at the University of Oklahoma Health Sciences Center, specialist in head-and-neck oncologic surgery, and program director for his hospital’s otolaryngology–head and neck surgery residency program, said that continuity of care is a major factor in weighing out the change in work hours.
First to consider is the paramount importance placed on patient care. “Following through with a patient from when you might meet them to how you make a diagnosis to subsequently initiating some sort of treatment is important, obviously, for the patient,” said Dr. Vasan. “But it’s just as important for the physician who is learning how to manage these patients.”
Second, patient care is helped along when staff are able to reduce the number of hand-offs and transitions of care. Limiting one member of a team to an hours limit to which others don’t have to adhere to opens the door to a problem in transferring information. “If you were to have frequent handovers, there’s potential for error,” Dr. Vasan added. “That’s why companies now exist that utilize software as a means to minimize errors and to make sure that everyone’s on the same page. This is something new that has been created because of work-hour restrictions.”
Dr. Zetterman said there is one major study that looked at hours limits and their impact on patient outcomes. The review, which was published in The New England Journal of Medicine in February 2016 and involved 117 U.S. general surgery residency programs and 151 hospitals, found that longer shifts and less time off between shifts were not associated with an increased rate of death or serious complications (9.1% in the flexible-policy group and 9.0% in the standard-policy group) or of any secondary postoperative outcomes studied (N Engl J Med. 2016;374:713-727). “That was certainly an added factor,” Dr. Zetterman said.
The third leg of the proverbial stool that is continuity of care is the health of physicians themselves, Dr. Vasan said. To wit, the NEJM surgical study found “no significant difference in residents’ satisfaction with overall well-being and education quality.”
“That’s one of the things the ACGME stresses, that physicians receive education in terms of recognizing fatigue and fatigue mitigation,” Dr. Vasan added. “It is important for physicians to have an opportunity to rest; that goes hand-in-hand with having these doctors work potentially 24 hours now.”
Dr. Rodney said that the 16-hour limit on interns meant that they could work a few of those shifts in a row, which could be more dangerous for them. “Sixteen hours on paper looks better than 24, but working 16 hours day after day instead of 24 hours with a post-call day off does not result in better quality of life,” she said, “and may actually lead to worse quality of life for the resident.”
Maintaining a Balance
Dr. Zetterman emphasized that while first-year otolaryngology residents and their program directors may be focused on raising the hours cap, the newly unveiled revision to the ACGME Common Program Requirements, the formal name of the rules that govern residents, is much broader. The five-year review placed a greater emphasis on patient safety and quality improvement, added a section to address the critical importance of physician well-being to graduate medical education and patient care, and implemented more explicit requirements regarding team-based care and professionalism, coupled with a framework for clinical and educational work hours that allows for flexibility, with a maximum that aims toward the ultimate goals of physician education and patient care.
Dr. Rodney said any changes that add plasticity to the rules for residents are good changes. “Inflexibility is a bad thing in medicine, because this is not a 9-to-5 job,” she added.
Dr. Vasan added that ACGME has a challenging task to ensure that residents are learning safely. But being equal to their senior peers is a major boon to first-year residents under the revised rules.
“Interns for otolaryngology are now within our specialty for six months out of 12 months,” he said. “Previously, they may have rotated through, say, one rotation of ear, nose, and throat, and the rest of the year would have been general surgery, and so on … If they’re going to be involved in patient care, they should be, in my opinion, working under the same work-hour limits, restrictions, or maximums as their contemporaries.”
That said, as a residency program director, he appreciates ACGME’s review of the available evidence every few years to tweak work hours, ensuring the best outcomes for patients and physicians. “There’s a very fine balance,” Dr. Vasan added, “between getting residents maximum experience within, say, a four to five-year block versus having a period of mental and physical rest that’s adequate throughout their training.”

Key Points
- Effective July 1, 2017, first-year resident limitations on work hours were revised, and all residents can now work the same number of hours.
- The new rules maintain an 80-hour-per-week cap on residents’ work but extend permissible work shifts for first-year residents from 16 to 24 hours.
- Continuity of patient care was a major factor in revising the guidelines.
Hospitalists as Test Subjects
Thanks to television shows like “MASH” and “Scrubs,” the image of exhausted physicians sleeping in any nook and cranny of a hospital they can find is a common one. But the ACGME works to make sure that’s not quite true.
The long hours of medical shifts, as compared with the more traditional eight-hour workday for many, have their origin in the early days of residency, when young physicians received brief periods of intense training. Over the years, residency evolved into a multi-year process and, as early as 1981, the ACGME Common Program Requirements for Graduate Medical Education in both internal medicine and pediatrics noted the “need for time for education and personal pursuits,” according to ACGME’s online history of work hours.
The first formal recommendations came in 1988, when a task force said residents should spend one day in seven away from a hospital and be on call no more than every third night. The next year, the now standard 80-hour workweek, averaged over four weeks, was put in place for internal medicine. Over the next few years, five more specialties added a weekly work-hour limit.
In 2001, ACGME created the Working Group on Resident Duty Hours and the Learning Environment. In large part, the report was inspired by the 1999 Institute of Medicine report, “To Err is Human,” which found that between 44,000 and 98,000 people die annually in hospitals due to preventable medical errors.
In 2003, the 80-hour weekly limit became standard for all specialties.
Fast forward to 2008, when ACGME was slated to “explore refinements” to its rules. The organization waited until 2010 for a report from Institute of Medicine and the Agency for Healthcare Research and Quality that examined resident hours.
Those standards were updated in 2010, and ACGME’s 2011 revisions were based in part on the updated version.
Timeline of Resident Work Hours
Early 1900s: Medical residents generally reside in a hospital; hence the term “resident.” House staff work every day and every other night.
Mid-1900s: Residents and interns are on call for 36 hours starting every other night, totaling more than 100 hours per week.
1975: Residents in New York City go on strike, calling for fewer hours. They return to work after hospitals agree to reduce on-call frequency from every other night to every third night.
1981: ACGME is formed.
1987: After Libby Zion’s case in 1984, New York State recommends an 80-hour limit on weekly resident duty hours, with no more than 24 consecutive hours on duty.
1990: ACGME sets an 80-hour workweek in four specialties (internal medicine, dermatology, ophthalmology, and preventive medicine) and limits on-call duties to every third night, with at least one 24-hour period off every seven days.
2001: Federal legislation is proposed to limit resident work hours.
2003: ACGME announces duty-hour requirements for all specialties, including an 80-hour workweek, one day off in seven, and a maximum shift length of 24 hours.
2011: ACGME restricts interns to 16-hour shifts.
2017: ACGME raises cap on resident duty hours to 80-hour weeks, with shifts of no longer than 24 hours, and up to an additional four hours for handoffs.
