Research Report
Overuse of health care services
represents a major source of wasted
health care spending in the United
States and is increasingly recognized as
a problem worldwide.
1
Overuse includes
services for which no medical basis exists,
that can harm patients, and/or that
may pose risks that exceed benefits.
2,3
Providing such services not only threatens
the financial sustainability of health
care systems but also exposes patients to
unnecessary risks,
4
generates burdensome
out-of-pocket expenses,
5,6
contributes to
undue anxiety for patients,
7
and often
delays or displaces needed care.
8
Overuse
has many drivers, including health care
system factors, the practice environment,
the culture of professional medicine,
and societal expectations for health care
delivery.
3
While these external influences
play an important role, patient–clinician
interactions remain the nexus of
decisions about inappropriate care.
3
It
is, therefore, imperative for physicians
to acquire the skills needed to promote
value in clinical encounters.
Promoting value in clinical encounters
requires an understanding of the
benefits, harms, and relative costs
of a medical intervention, as well as
the ability to apply this knowledge to
individual patient interactions.
9
For
example, physicians encounter patients
requesting unnecessary diagnostic
or therapeutic procedures
10,11
(e.g.,
a computed tomography [CT] scan
for acute musculoskeletal low back
pain, antibiotics for a viral illness).
Conversations should focus on the
premise that more medical care is
not always better care.
9,12
However,
many physicians find these “less-is-
more”
9
conversations difficult,
13
and
sophisticated communication skills are
needed to respond to such requests in
patient-centered and time-efficient ways.
Medical education has a responsibility
to address rising health care costs,
14
and equipping students with practical,
patient-centered strategies to curb
overuse is an important means by which
to do this. To support educators in this
endeavor, we developed a standardized
patient (SP) scenario assessing medical
students’ ability to respond to requests
for unnecessary testing. Previously,
we published validity evidence from a
single institution supporting the use of
the resulting scores for this purpose.
9
We found that scores from this “less-is-
more” scenario did not correlate with
faculty ratings of students’ interpersonal
and communication skills on clerkships,
suggesting that the skills required to
promote value in clinical encounters are
distinct from those needed for regular
communication. The vast majority of
participating students also reported that
the scenario helped improve their high-
value communication skills.
9
Based on these findings, we implemented
the less-is-more scenario at 4 additional
medical schools across the United States
and undertook a multisite study both
Abstract
Purpose
To examine validity evidence for a
standardized patient scenario assessing
medical students’ ability to promote value
using patient-centered communication
(in response to a patient requesting an
unnecessary test) and to explore the
potential effect of various implementation
and curricular factors on student scores.
Method
Third-year medical students (N = 516)
from 5 U.S. MD-granting medical schools
completed the communication scenario
between 2014 and 2017 as part of
a larger objective structured clinical
examination (OSCE). Centralized raters
assessed performance using an 11-item
checklist. The authors collected multiple
sources of validity evidence.
Results
The mean checklist score was 0.85
(standard deviation 0.09). Interrater
reliability for checklist scores was
excellent (0.87, 95% confidence
interval = 0.78–0.93). Generalizability
and Phi-coefficients were, respectively,
0.65 and 0.57. Scores decreased as
the number of OSCE stations increased
(r = -0.15, P = .001) and increased
when they were used for summative
purposes (r = 0.26, P < .001). Scores
were not associated with curricular time
devoted to high-value care (r = 0.02,
P = .67) and decreased when more
clerkships were completed before the
assessment (r = -0.12, P = .006).
Conclusions
This multisite study provides validity
evidence supporting the use of scenario
scores to assess the ability of medical
students to promote value in clinical
encounters using patient-centered
communication. Findings illuminate the
potential effect of OSCE structure and
purpose on student performance and
suggest clerkship learning experiences
may not reinforce what students
are taught in the formal curriculum
regarding high-value care. Devoting more
time to the topic appears insufficient to
counteract this erosion.
