Research Report
In the last 20 years, evidence-based
medicine (EBM) has become a standard
component of the medical school
curriculum.
1
Despite this ubiquitous
inclusion, physicians’ practice of EBM
is suboptimal,
2–4
which has implications
for patient safety, cost-effectiveness, and
consistency of care.
5,6
The suboptimal
practice of EBM has prompted
researchers to explore challenges to
physicians practicing, clinician educators
teaching, and students learning EBM.
In research on barriers to practicing
EBM in clinical settings, the challenges
reported by physicians have included
a lack of time, conflicts between
evidence-based recommendations
and patient preferences, and weak
available evidence.
4,7,8
Additionally,
EBM instructors have described
barriers to teaching EBM in clinical
care. These barriers include a lack of
time for teaching EBM, an absence of
EBM requirements for trainees, and
their own, as well as trainees’, lack of
EBM knowledge and skills.
8
On the
basis of these studies, researchers have
suggested that the challenges reported
by physicians and EBM instructors
be considered when designing EBM
curricula, as they may have implications
for student learning. For example,
if physicians are challenged by time
constraints and fail to practice EBM,
then students may have limited exposure
to optimal EBM role models, which
could impact their learning experiences.
Although research on these barriers
may inform student training, it does not
directly examine the challenges medical
students may face when learning EBM,
which may differ and contribute to the
suboptimal practice of EBM.
Research on challenges to students
learning EBM is limited and focused
on training in clerkship settings. For
example, two studies found that the
challenges to learning EBM in clerkships
included receiving minimal support
from clinical teachers for using EBM
and limited opportunities for practicing
EBM.
9,10
Knowledge of the EBM
learning challenges faced in clerkships is
important but narrow in scope, as EBM
training can be offered across all years
of medical school.
11
Researchers have
also studied barriers that faculty perceive
in implementing EBM curricula.
12–14
However, these studies focus on barriers
to the delivery of EBM curricula such as
lack of curricular time.

Our study aims to identify learner-
centered challenges that medical students
face across medical schools when learning
EBM. With these challenges identified,
we then explore potential solutions by
examining the educational approaches
used by medical schools to overcome
them. Thus, our study aims to identify
Abstract
Purpose
Evidence-based medicine (EBM) is a
fixture in many medical school curricula.
Yet, little is known about the challenges
medical students face in learning EBM or
the educational approaches that medical
schools use to overcome these challenges.
Method
A qualitative multi-institutional
case study was conducted between
December 2013 and July 2014. On the
basis of the Association of American
Medical Colleges 2012 Medical School
Graduation Questionnaire data, the
authors selected 22 U.S. and Canadian
Liaison Committee on Medical
Education–accredited medical schools
with graduates reporting confidence
in their EBM skills. Participants were
interviewed and asked to submit EBM
curricular materials. Interviews were
audio-recorded, transcribed, and
analyzed using an inductive approach.
Results
Thirty-one EBM instructors (17 clinicians,
11 librarians, 2 educationalists, and 1
epidemiologist) were interviewed from
17 medical schools (13 in the United
States, 4 in Canada). Four common EBM
learning challenges were identified:
suboptimal role models, students’ lack of
willingness to admit uncertainty, a lack of
clinical context, and students’ difficulty
mastering EBM skills. Five educational
approaches to these challenges that
were common across the participating
institutions were identified: integrating
EBM with other courses and content,
incorporating clinical content into EBM
training, EBM faculty development, EBM
whole-task exercises, and longitudinal
integration of EBM.
Conclusions
The identification of these four learner-
centered EBM challenges expands on the
literature on challenges in teaching and
practicing EBM, and the identification
of these five educational approaches
provides medical educators with
potential strategies to inform the design
of EBM curricula.
