Ryan, a first-year resident, lacks depth in his clinical presentations and relies solely on UpToDate without referencing appropriate medical literature. Dr. Waters encourages Ryan to be more self-directed by following the process of evidence-based medicine (EBM). EBM involves integrating individual clinical expertise with the best external evidence from studies. Dr. Waters can role model EBM for Ryan by completing self-directed learning activities that include formulating answerable clinical questions, efficiently searching medical literature, and critically appraising evidence. Nonadherence to practice guidelines is a major barrier to successfully applying EBM.

Learning Objectives
• How to use and teach principles of EBM.
• How to use a variety of medical information
resources in self-directed learning activities.
• Encouraged to promote learner self-assessment
of learning needs as a prerequisite for self-
directed learning.
• Incorporate principles of EBM to assist
learners in critically evaluating sources of
medical information.

3. Learner Scenario
Ryan is a first-year resident beginning the 2nd month of an
internal medicine rotation with Dr. Waters at the Feel Good
Health Center. Together each day Dr. Waters and Ryan
identify a clinical problem related to a specific patient seen
that day, which Ryan is then assigned to research and
present his findings to Dr. Waters and other clinical staff the
next day.
While Ryan appeared to make an effort with his initial
presentations, they lacked depth and lacked any references
to appropriate medical literature.
After presenting for the third time, Dr. Waters asked Ryan to
describe his approach to research the clinical problems
assigned to him. Ryan glibly responded, “I don’t see what
the big deal is. I find using Up-to-Date to research things just
makes sense and is the most efficient use of my time.”Ryan
How can you encourage Ryan to be more self-directed?

4. A Self-Directed Learner
identifies what s/he needs to do
(acquire knowledge, skills, or attitudes),
develops and executes a plan for
responding to those needs, and
reviews the outcomes of that plan.
… is a proactive advocate for his/her own learning:

understands the process
and expectations for self-
directed learning

accordingly

8. How do Roles ofTrainee
and Preceptor Change in SDL?
LEARNERS seek articles on conditions of the
patients, ask questions
FACULTY/PRECEPTORS give learners opportunities
to interact with patients and feel a part of the practice

3rd stages of Stritter’s Professional
Development

(e.g., Asthma, COPD, Coronary Artery Disease, Diabetes, Heart
Failure)
Understand Principles of Efficient
Resource Utilization
Develop Skills in Patient Education

12. What is Evidence-based Medicine?
Evidence-based Medicine (EBM)
involves the integration of
individual clinical expertise
with the prudent use of the
current best external evidence
in making decisions about
the care of individual
patients.

ASSESS the Patient & ASK
a SearchableQuestion
P – Patient, Population, or Problem
(The disease and the patient characteristics, if pertinent)
I – Intervention, Prognostic Factor, or Exposure
(Drug, procedure, diagnostic test, exposure)
C – Comparison or Intervention (if appropriate)
(Main alternative to the intervention)
O – Outcome you would like to measure or achieve
(Measurable i.e., Rather than “more effective”, use something
that can be measured like “decreases all-cause mortality”)

Components of Clinical Questions
(can be applied to tx, dx, or risk)
Here are 3 examples of PICO questions.

I Intervention / indicator = ?
C Comparator / control = ?
O Outcome = ?
Emma is a 6-week-old baby at her routine follow-up. She
was born prematurely at 35 weeks. You want to tell the
parents about her chances of developing hearing problems.
Question: In infants born premature, compared to
those born at full term, what is the subsequent lifetime
prevalence of sensory deafness?
