Physicians perform poorly when Patients need
Special Care
Newswise, July 2010 — Patients often receive inappropriate
care when their doctors fail to take into
account their individual circumstances,
according to a new study by the University
of Illinois at Chicago and the VA Center for
Management of Complex Chronic Care.
The study of physician performance is the largest ever to
be conducted using actors presenting as
patients in doctors' offices. It appears in
the July 20 issue of Annals of Internal
Medicine and was funded by the
Department of Veterans Affairs.
"Physicians did quite well at following guidelines or
standard approaches to care, but not so well
at figuring out when those approaches were
inappropriate because of a particular
patient's situation or life context," said
Dr. Saul Weiner, associate professor of
medicine and pediatrics at UIC and staff
physician at the Jesse Brown VA Medical
Center, who was lead author of the study.
Weiner said physicians need to understand why a patient is
failing, for instance, to control their
asthma, rather than just increase the dose
of the drugs they prescribe. Specific issues
-- such as the lack of health insurance, the
need for less costly treatment, or
difficulty understanding or following
instructions -- must be recognized when
making clinical decisions. Inattention to
such issues leads to what are called
"contextual errors" in patient care.
The study used actors trained to simulate real patients in
400 visits to a wide range of physician
practices in Chicago and Milwaukee,
including several VA sites. At each clinic,
identities were created along with medical
records and insurance information for the
actor-patients. The doctors had all agreed
to participate in the study but were not
told which patients were actors.
Unlike real patients, the actors, or "unannounced
standardized patients," consistently adhere
to a script, enabling researchers to make
comparisons of physicians' performance
across the visits, said co-author Alan
Schwartz, a methodologist and UIC associate
professor of clinical decision-making.
Four case scenarios, each representing a common outpatient
condition, were developed. Each case had
four variants -- uncomplicated, biomedically
complex, contextually complex, or both
biomedically and contextually complex.
The actors followed scripts that contained hints or "red
flags" of significant issues which, if
confirmed, would need to be addressed to
avoid error. The actors always started with
the same two red flags, but were randomly
assigned to respond differently based on the
variant.
For example, in a case involving a 42-year-old man
concerned about worsening asthma, the actor
mentioned both a biomedical red flag
(coughing at night) and a contextual red
flag (losing his job) that suggested acid
reflux and loss of health insurance,
respectively, as a key part of the problem.
The study looked at whether the physician picked up on the
red flags and implemented an appropriate
care plan for each of the case variants.
At visits where no modification of customary practice was
required, 73 percent of physicians provided
error-free care.
But at visits where individualizing care required an
alternative to the customary treatment, only
22 percent of physicians provided error-free
care during a contextually complicated
encounter, 28 percent during a biomedically
complicated encounter, and 9 percent during
a combined contextually and biomedically
complicated encounter.
"To date, measures of doctors' performance have focused on
situations where knowledge of the individual
patient is ignored," said Weiner. "Under
those conditions, physicians did fairly
well. But as soon as care required more than
following an algorithm -- finding out what's
really going on with a patient and acting on
that information -- only a minority of
physicians got cases right."
The researchers also looked for differences related to
physician demographics, training and
experience; and for each case they had
matched black and white actors randomly
assigned to physicians. They also evaluated
total time spent with the simulated
patients.
"We expected that if physicians had more time with
patients, they would be more likely to
individualize care," Weiner said. "But what
we found was that among those visits where
physicians did a great job identifying
contextual issues and addressing them, they
did not on average spend any more time with
patients than the physicians who didn't
recognize contextual issues. That was
surprising."
The study found that physicians were more likely to respond
to the biomedical rather than contextual red
flags even when both were equally important
to planning appropriate care. "We believe
that reflects the way in which physicians
are educated," said Weiner. "The lesson here
is that there has to be a dramatic change in
the way we train physicians."
