Recreating the residency
Under new rules, residents may not work more than 80 hours a week. This
change has forced physicians to rethink the underpinnings not only of
training, but also of patient care.

On the night of March 4, 1984, an 18-year-old patient named Libby Zion
was admitted to the emergency room of Cornell Medical Center’s New
York Hospital complaining of fever and an earache. Just hours later, while
in the care of the hospital’s residents, she lay dead. Zion’s
father, Sidney Zion, was a prominent, well-connected journalist and a
former federal prosecutor, and in what would soon become notorious as
“the Zion case,” he and his wife filed suit, claiming that
the negligence of the hospital’s overly fatigued and poorly supervised
house staff was the direct cause of their daughter’s death.

In the end, a New York grand jury did not find sufficient evidence
that overtired residents were responsible for Zion’s death, and
postmortem lab results suggested that she had died from an overdose of
cocaine. But the enormous publicity surrounding the Zion case cast a bright
light on aspects of graduate medical education that the American public
had long ignored. Medical residents’ duty hours, once an esoteric
and jealously guarded prerogative of medical school faculty and hospital
administrators, had become the focus of intense interest on the part of
legislators and regulatory boards nationwide.

In the wake of the Zion case, New York state and Puerto Rico enacted
statutes that set limits on duty hours for hospital house staff. But the
most significant shock wave from the case wasn’t felt until July
2003, when the Accreditation Council for Graduate Medical Education (ACGME),
citing concerns for patient safety, imposed strict limits on residents’
duty hours at all teaching hospitals. Though the rules themselves are
straightforward—they limit residents to an 80-hour workweek and
24 continuous hours on call, and guarantee one day off each week—they
have set off a sea change in American medical education and patient care.
The traditional residency system was deeply ingrained in the educational
structures of medical schools, and the presence of hardworking, inexpensive
house staff has long been taken for granted by hospitals in their day-to-day
operations.

Yale is no exception. Some 175 new residents in specialties as
diverse as anesthesiology and urology arrive in New Haven each year. Though
most of these residents are technically employees of Yale-New Haven Hospital
(YNHH), the dual educational and clinical missions of residency are reflected
in the Graduate Medical Education Committee, which directly oversees the
program and reports both to the chief of staff at YNHH and to the dean’s
office at the School of Medicine.

Some residency programs, such as pediatrics and psychiatry, have adapted
fairly easily to the new rules, but for others the regulations have forced
a sweeping re-evaluation of both education and patient care. For example,
the sheer size and complexity of the residency program in internal medicine,
which shepherds 180 residents through 13 clinical rotations at four different
hospitals each year, have required painstaking organizational and educational
adjustments.

“The structure of the program at Yale has been built over
the last 50 years, and it has been built in pieces, so nobody knew when
you changed one piece what the domino effect would be,” says Asghar
Rastegar, M.D., professor of medicine (nephrology) and associate chair
for academic affairs. “This is sort of like a spring cleaning. Every
room in the house had to be looked at.”

Institutions that skirt the new rules do so at their own peril.
In 2002 the ACGME threatened to withdraw accreditation of the surgical
residency program at Yale for violations of its previous duty-hours guidelines,
and the accrediting board has come down hard on other elite programs since
July 2003. Residency programs at Johns Hopkins, Duke and the University
of Rochester have been subjected to similar “adverse actions”
by the ACGME. However, just one year after the new rules took effect,
Rosemarie L. Fisher, M.D., HS ’75, professor of medicine (digestive
diseases) and director of graduate education at the School of Medicine,
says that Yale has adapted well. According to Peter N. Herbert, M.D. ’67,
HS ’69, chief of staff and senior vice president for medical affairs
at YNHH, the close call with the surgical program’s accreditation
may have been a blessing in disguise: the crisis led YNHH to take steps
over the past two years—the Department of Surgery hired 12 physician
assistants to lighten residents’ workloads, for example—that
put Yale ahead of the curve for compliance.

Herbert says that problems arising from the new regulations may loom large
at the moment, but he is confident that the rules will present few difficulties
for Yale or for graduate medical education in general in the long run.
“I think all of these concerns will be history in two or three years,”
Herbert says. “We will find a way to educate our residents and to
give them all the necessary experiences, in and out of the operating room,
and at the same time take good care of patients.”

Education or service?
It has been a screenwriter’s staple since the earliest days of television
medical dramas. A harried hospital resident, running on empty after yet
another all-nighter, slinks into a darkened storeroom during an unexpected
lull. The young doctor lies down and closes her eyes. But after just a
few seconds of blessed sleep, the door bursts open—emergency! Cut
to our rudely awakened heroine, who shakes off her drowsiness and rushes
off to slay whatever dragon may await.

Any doctor knows that the relentlessly action-packed arena of ER
only faintly resembles the everyday practice of medicine, but the stock
character of the sleep-deprived resident is drawn from real life, and
has been a familiar figure in hospital hallways for a century.

The punishing life of the resident, like many other features of
graduate medical education in America, was a product of innovations in
medical education made by William Halsted, M.D., a Yale College graduate
who founded the vastly influential surgical training program at the Johns
Hopkins Hospital during the 1890s.

For Halsted, who strongly admired the German medical system of his day,
“residency” was literal: he required doctors in training to
live at the hospital, and he discouraged his charges from marrying to
ensure that they gave their all to the profession. His residency system
combined the rigor of boot camp, the asceticism of the monastery and the
esprit de corps of a college fraternity.

Senior physicians often speak of this system as if it had been
in place since Hippocrates, but as Kenneth M. Ludmerer, M.D., professor
of medicine and history at Washington University in St. Louis, says, residency
was only one of many possible routes to medical specialization in Halsted’s
time, and it did not become the dominant system in graduate medical education
until the 1920s. Moreover, says Ludmerer, author of Time to Heal: American
Medical Education From the Turn of the Century to the Era of Managed Care,
residency was originally considered a privilege reserved for a few students
who had demonstrated promise for an academic career, and a high attrition
rate was considered a virtue.

“The concept was to start with a broad range of talented
individuals, and of those, to select the very best,” says Robert
Udelsman, M.D., M.B.A., Lampman Professor of Surgery and Oncology, chair
of the Department of Surgery and chief of surgery at YNHH. This model
was known as the “pyramidal system,” because fewer residents
remained in a program each year; only those at the top tier survived to
become senior or chief residents.

After World War II, several trends converged to “democratize”
residency, vastly increasing enrollments in residency programs. An explosion
in medical knowledge made specialization increasingly necessary, and there
was growing pressure on faculty at teaching hospitals to provide clinical
care while pursuing research. The availability of more residents to care
for patients freed faculty for laboratory work, and residents took on
more responsibility for teaching medical students. By the 1950s, grueling
100-hour workweeks had become the norm for residents, but the system was
remarkably efficient and cost-effective. As Udelsman says, residents “worked
like the devil, didn’t complain too much and saved hospitals a fortune.”

But according to medical historian Ludmerer, the educational mission of
residency suffered greatly as hospitals increasingly relied on house staff
for clinical care. “The dominant theme in the history of graduate
medical education is the ongoing tension between education and service,”
Ludmerer says. Graduate medical education still comes under fire for overemphasizing
service and de-emphasizing education, a charge leveled since the 1930s,
he says.

If anything, the devaluing of residents’ educational experience
has only increased in the era of managed care—patients admitted
to the hospital are far sicker and require more medical care than inpatients
of a generation ago. Moreover, in the face of the recent nursing shortage
residents have shouldered duties that have little or no relevance to the
education of a physician. Because patient care must always take precedence
over opportunities to teach medical students, medical school education
has suffered as well. Nevertheless, Herbert says, arguments to reform
residency to better meet educational goals have largely fallen on deaf
ears, while the patient-safety crusade that grew out of the Zion case
ultimately carried the day, leading directly to the ACGME’s restrictions
on duty hours.

Unintended consequences
Like military service or athletic competition, enduring the trials of
traditional residency has been a source of great pride and camaraderie
for generations of physicians and has undoubtedly burnished the profession’s
mystique in the public mind. But whatever its romantic aspects, the intense
schedule of the medical resident had a purely practical benefit known
as “continuity of care”: by treating newly admitted patients
for long, uninterrupted stretches, budding doctors could see the natural
course of disease and the effects of treatment unfold in ways no textbook
could describe.

The new limitations on duty hours inevitably create breaches in
continuity of care. Under the ACGME rules, residents must leave the hospital
when their shift is over regardless of the clinical situation at hand,
and the lack of flexibility in this regulation is the greatest source
of dissatisfaction among both faculty and residents.

Robert J. Alpern, M.D., the Ensign Professor of Medicine (nephrology)
and dean of the School of Medicine, says that “continuity of care
was one of the best parts of the educational experience. Limiting continuity
of care is especially bad for education because you learn about a patient
much better if you follow them through their whole treatment.” Surgery
chair Udelsman agrees. “I don’t think there’s any question
that the residents are sleeping more, are home more, and I think they
basically like that,” he says. “There’s also no question
that they’re not getting as much exposure to patient care as they
used to. There’s no getting around it.”

The same is true for medical students, whose schedules are tethered to
resident teams’ shifts, says Herbert S. Chase Jr., M.D., professor
of medicine (nephrology) and deputy dean for education at the medical
school. “One learns by observing a patient live the natural history
of an illness from beginning to end,” Chase says. “In the
future, students are going to have to piece together the mosaic of a syndrome;
they’re only going to see snippets of it. It will never be the same.”

But the advantages of continuity of care are not just educational.
Though it might seem obvious that better-rested physicians will improve
patient safety, Rastegar says that rigorous studies on this question in
a medical setting are sparse and inconclusive. David J. Leffell, M.D.,
HS ’86, professor of dermatology and surgery and associate dean
for clinical affairs, has similar concerns. “I don’t know
if there’s any evidence that an 80-hour workweek is advantageous
apropos risk,” says Leffell. “It seems like an arbitrary figure.”

On the other hand, there were some clear advantages to the traditional
residency’s longer hours. For one thing, longer schedules meant
fewer “handoffs” of patient histories and test results from
one resident to another when signing out. Fisher used to warn residents
to be especially vigilant about the possibility of medical errors during
handoffs, which she says can come perilously close to the children’s
game of “Telephone”—information passed from one person
to another changes as it moves down the line. Though the pitfalls of handoffs
are more subtle than resident fatigue and have largely escaped the notice
of regulators, Rastegar says that two studies published in the 1990s in
Annals of Internal Medicine and JAMA: The Journal of the American
Medical Association presented convincing and worrisome data to back
up Fisher’s concern. “There’s a trade-off between a
rested team and handoffs,” he says. “Often handoffs have more
negative impact on patient care than residents who have worked longer
hours.”

Herbert says that some of these problems should diminish over the
next three years as YNHH becomes an increasingly “paperless”
hospital. “We need exquisitely tight signoff systems from caregiver
to caregiver when we have so many more individuals involved in the care
of patients,” he says. “The handoff with index cards and paper
sheets is still going on, but there’s a lot of effort on computerized
formats for doing signout, so any caregiver can go into the computerized
medical record and see the major concerns and things that need to be followed
up in patient care.”

Even as systems are put in place to alleviate procedural issues,
many faculty worry that the new rules will create a “shift-worker”
mentality in residents that will erode the absolute commitment to patient
care so esteemed in traditional residency. Reports of residents at other
institutions being physically forced to leave hospitals at the moment
their duty hours end are troubling to those trying to instill absolute
dedication to patients’ welfare at Yale. “Those are the residents
you want to be your doctor when they leave,” says Leffell, “because
they’re the ones who care the most.”

Meeting the challenge
Whatever the shortcomings of the new rules, those entrusted with implementing
them are convinced that they are here to stay. Instead of greeting the
ACGME ruling with a grudging passivity, Yale faculty and YNHH administrators
have seized the moment to examine the fine structure of the residency
system at Yale. Their ultimate aim is not rote compliance with the rules,
but a reinvention of medical training that meets requirements but exceeds
expectations in both education and clinical care.

For example, surgical volume is sharply up in Udelsman’s
department, which has added 22 surgeons to the faculty in just the past
two years. Because today’s hospital patients need a great deal of
care, the reduction in resident duty hours has required junior faculty
to perform many tasks formerly handled by interns; some assistant professors
are logging in excess of 80 hours a week since the ACGME rules were enacted,
Udelsman says.

His department has hired a dozen physician assistants to relieve
residents and comply with the rules, but Udelsman suggests that tapping
retired surgeons in the New Haven area would be a creative way to take
up even more clinical slack. “What a waste to have these people
sitting at home doing crossword puzzles when they could be in the operating
room two or three days a week doing what they love to do,” he says.
“It could be a win-win situation.”

In the Department of Internal Medicine a hospitalist service has been
formed to care for an increasing number of patients who cannot be cared
for by the medical house staff.

When it became clear that restrictions on duty hours were inevitable,
Rastegar and his colleagues in the Department of Internal Medicine began
to convene regular meetings of residents, chief residents and faculty
to take a fresh look at house staff policies. “There was no blueprint
to follow,” says Rastegar. “We had to develop it locally for
our own hospital, and we knew we wouldn’t get it right the first
time.”

They didn’t. A system in place last year was deemed unworkable
and was jettisoned in favor of the current model, which is based on teams
of two senior residents and two interns (first-year residents) under the
watchful eye of an attending physician. Two medical students are assigned
to each team.

One resident/intern pair in a team arrives for duty at about 7:30
a.m., working through the night and admitting new patients until 7:30
the next morning, when the other resident/intern pair arrives. The first
pair is now deemed to be “postcall”; according to the new
ACGME regulations, this pair may hand off patient care to the second team
during rounds, but they may not admit new patients and they must refrain
from any other clinical duties not crucial to continuity of care.

After rounds, which start at 7:30 a.m. and last until about 9 a.m., responsibility
for the unit’s patients is in the new pair’s hands, and with
the medical student’s help, the first team’s intern completes
orders for tests and medications and any other paperwork. The postcall
pair are also permitted to use any of their remaining six hours for conferences
or other educational activities.

At 1 p.m., after a 30-hour shift, the first pair is officially
off duty until the next morning’s rounds. Each resident/intern pair
completes two such shifts per week, and puts in two days’ worth
of more standard hours to approach the 80-hour maximum.

In the previous model, one resident supervised two interns, who
could each admit five new patients and one patient transferred from another
ward. Though interns can still admit the same number of patients, having
two residents on the team should significantly improve both patient care
and education, says Cyrus R. Kapadia, M.D., FW ’78, professor of
medicine (digestive diseases) and director of the residency training program.
“Now the resident has time to read more about a couple of his or
her patients, and to spend more time teaching the intern and the medical
student,” Kapadia says.

The ACGME has been unwavering in its enforcement of the 80-hour week,
which faculty members say was probably necessary for hospitals to take
the ruling seriously. And everyone agrees that they would much rather
police their own programs in concert with the ACGME than submit to auditing
by a government agency in the event that federal restrictions on duty
hours were passed.

An unexpected gift
“House staff and trainees are probably more conservative than faculty,”
says Fisher. “They’ll tell you all the time that they’d
love to see change, but when it comes to making major changes, ‘Well,
maybe you can do it next year, when I’m gone.’ ”

Perhaps, but Farshad Abir, M.D., a fifth-year administrative chief
resident in surgery who completed the first two years of his residency
before the new rules took effect, has no doubt that the ACGME-mandated
changes are all for the better. “Just like anything in life, when
you start something new you’re going to have kinks that need to
be ironed out,” Abir says. “But I think definitely we’re
moving in the right direction—100 percent.

“The way it used to be was awful,” says Abir, who regularly
logged 120-hour weeks as a junior resident. The chance to straddle both
systems has given him “perfect training,” he says, because
having learned to budget his time under the old rules, he views the new
workweek as an unexpected gift of 40 extra hours.

Surgery chair Udelsman would understand. Recalling his own resident
days, he says, “I saw my kids at 11 at night when I got home. My
wife would wake them up so I’d actually see them once in a while!”
Udelsman believes that the traditional residency, whatever its strengths,
created “abusive” physicians, and Herbert agrees: “You
can’t treat physicians like work animals and expect that they’ll
come out of it with correct attitudes,” he says. “I think
in the end we’ll have more humane surgeons.”

Although Herbert’s YNHH desk sits squarely at the center
of the fray in implementing the new ACGME regulations, he exudes confidence
when asked about the future. “It’s a radical change for those
of us who are members of the old guard, and we can’t believe that
we can play on this field, but in fact we will play on it,” Herbert
says. “Patient care will be as good, and education will be as good
as well.” YM

A day in the life
By 7:15 on a recent Monday morning, intern Loida Viera, M.D., and second-year
resident Charles Dela Cruz, M.D., have been working for 24 hours straight
in YNHH’s new Acute Care for the Elderly (ACE) unit. Viera admitted
six patients to the unit during the night, and she and Dela Cruz are preparing
for “work rounds,” during which they will convey all they
know about the new patients to their counterparts on their residency team,
intern Robert Bercovitch, M.D., and second-year resident Francis Chan,
M.D. Medical student Robert McGlynn will join them.

Along with attending physician Leo M. Cooney Jr., M.D. ’69,
Humana Foundation Professor of Geriatric Medicine, the five move in a
tight pack through the hallways before coming to rest in the hall outside
the room of a newly admitted patient. By tradition, interns present cases,
and Viera, a freshly minted graduate of Tulane University School of Medicine,
betrays no fatigue or uncertainty as she fashions clipped, efficient clinical
narratives from the blizzard of acronyms, abbreviations and numerals that
are the lingua franca of modern medicine.

The truism that today’s patients are far sicker than those
under residents’ care 30 years ago is nowhere more true than in
Cooney’s ACE unit. As Viera presents updates on the unit’s
more familiar cases, Chan and Bercovitch must keep track of multiple diagnoses,
a litany of test results and combinations of several medications for each
patient as they prepare for their shift.

By 9 a.m., the handoff is complete, and Dela Cruz and Chan are
free to attend residents’ report, an informal one-hour exchange
of ideas among the chief resident, attending physicians and house staff,
while Bercovitch keeps an eye on patients in the ACE unit. Meanwhile,
Viera huddles in front of a computer screen in a small ACE workroom with
McGlynn, using the six postcall hours that remain under Accreditation
Council for Graduate Medical Education (ACGME) rules to complete paperwork
and order tests and medications for her patients.

At 11 a.m., the four residents and interns are reunited for attending
rounds, where Cooney compresses more than 30 years of clinical wisdom
into a one-hour lecture based on cases of interest in the unit. Today’s
topics: gout and pressure sores, two banes of geriatric medicine. Cooney
seamlessly weaves anecdotes from his hospital experiences and his days
as a volunteer physician at a homeless shelter together with précis
of recent articles on molecular medicine, and delivers the whole package
with warmth and humor.

After a thorough review of Viera’s notes, Dela Cruz attends
a lunch conference and leaves at 1 p.m. On those days when her notes are
complete, Viera leaves at noon. She may opt to spend her lunch hour at
Fitkin Amphitheater, where a changing cast of faculty present intern-friendly
lectures on various clinical concepts.

Viera will return at 7:15 the following morning, but for now Chan
and Bercovitch have taken the reins.

For Asghar Rastegar, M.D., professor of medicine (nephrology) and
associate chair for academic affairs, the key to preserving professionalism
and a commitment to patient care under the new rules lies in a “cultural
shift”: residents must be convinced, he says, that patients’
interests will be best served when they scrupulously watch out for their
teammates. He and his colleagues have taken pains to see that the handoff
process is not only thorough, but sufficiently reassuring for dedicated
residents to go off duty with a clear conscience.

“It only works if you know that the team behind you is going
to do everything possible to take care of the patient and take care of
you, and if they know that you will do the same thing,” Rastegar
says. “That you cannot write on a piece of paper.”
