Patient Presentation
• Details of patient presentation that prompted
the clinical question
Clinical Question
• State the clinical question
Background
• What general knowledge about the clinical topic
and or disease is needed PRIOR to searching for
evidence to answer your specific clinical
question?
• Limit background slides to 2 slides at most
Search Strategy
• List the data sources you utilized
• If you conducted a search of an electronic
database, summarize your search strategy
Search Results
• For each data source, list the types of
information that you identified
–
–
–
–
–
RCT
Case-control studies
Cohort studies
Case series
Guidelines, expert opinions, review articles
Evidence Appraisal
• List which of the identified sources were
appropriate to your specific clinical question
• Summarize how you determined which of the
identified studies were appropriate to use in
answering your specific clinical question
• Remember, you are not trying to present ALL
of the evidence, just the BEST evidence
Evidence Appraisal
• For each BEST evidence source, perform a
critical appraisal, to include some or all of the
subsequent slide content
• You must critically evaluate EACH evidence
source that you believe helps to answer your
clinical question.
Hypothesis
• If an analytic study, what is the hypothesis that
is being tested?
Objectives
• What are the primary and secondary objectives
of the study?
Methods: Design
• What type of study was done?
Primary research (experiment, randomized
controlled trial, other controlled clinical trial, cohort
study, case control study, cross sectional survey,
longitudinal survey, case report, or case series)?
Secondary research (simple overview, systematic
review, meta-analysis, decision analysis, guideline
development, economic analysis)?
• If a “randomized trial” was randomization truly
random?
Methods: Setting
• What is the setting in which the subjects were
studied (e.g. inpatient, outpatient, community
hospital, teaching hospital, university)?
• If a clinical investigation, was the study
conducted in “real life” circumstances?
Methods: Subjects
• Who is the study about?
How were subjects recruited?
Who was included in and who was excluded from
the study?
Methods: Interventions
• What intervention or other maneuver was being
considered?
Methods: Outcomes
What outcome(s) were measured and how?
• Was assessment of outcome (or, in a casecontrol study, allocation of cases) “blind”?
Was follow-up complete?
Methods: Statistics
• What sort of data do the authors have?
• What types of statistical tests were used and
were they appropriate to the data type?
• Have the data been analyzed according to the
original study protocol?
Results
• Were the groups similar at the start of the trial?
• Aside from the experimental intervention, were
the groups treated equally?
• What are the key results?
Conclusions
• Do the results support the original study
hypothesis?
Commentary
• Does the evidence you found help to answer
your original clinical question?
– Can the results be applied to my patient case?
– Will the results lead directly to selecting or avoiding
therapy?
– Are the results useful for reassuring or counseling
patients?
Recommendation
• State what specific recommendation that you can make (if any)
in regards to your clinical question and list the level of evidence
for each recommendation:
– Level I: Evidence obtained from at least one properly designed RCT
– Level II-1: Evidence obtained from well-designed controlled trials
without randomization
– Level II-2: Evidence obtained from well-designed cohort or case-control
studies analytic studies
– Level II-3: Evidence obtained from multiple time series, with or without
the intervention
– Level III: Opinions of respected authorities, based on clinical experience,
descriptive studies, or reports of expert committees
