Primary (Original) Studies
Articles that report results of original research investigations
Conclusions supported by data and reproducible methodology
Good Source: MEDLINE (OVID)
Review Articles
Background articles that provide an overview of current research
Integrate recent advances with accepted practice
Summarize – not original works May mix opinions/bias of the authors with
evidence Good Source: MD Consult
Systematic Review
Analyzes data from several primary studies to answer a specific clinical question
Provides search strategies and resources used to locate studies
Includes specific inclusion and exclusion criteria (results in less bias)
Meta-Analysis (subclass) statistically summarizes results of several individual studies
Good Source: Cochrane DSR; All Evidence Based Medicine Reviews
Characteristics of Information Retrieval for Patient Care Using research findings versus conducting research Retrieving and evaluating information that has direct
application to specific patient care problems Selecting resources that are current, valid, and
available at point of care Developing search strategies that are feasible within
time constraints of clinical practice

Evidence Based Medicine
The incorporation of the highest quality of information, derived from scientific study, into the context of clinical care
Steps Defining an evidence-based question Identifying and critically appraising the best
available scientific evidence to answer the question
Deciding on the most appropriate course of action for a given patient
Evidence Based Questions
Four basic types of clinical questions: Diagnosis Treatment/prevention Etiology Prognosis
Certain types of clinical studies constitute highest level of evidence for each type of question
Randomized controlled trials are considered the best studies for assessing therapeutic interventions.
Source: Sackett, D.L., Richardson, W.S., Rosenberg, W.M.C., & Haynes, R.B. (1996). Evidence-Based Medicine: How to practice and teach EBM. London: Churchill-Livingstone.
Levels of Evidence
Grade the quality of evidence based on the design of the clinical study
Variety of hierarchies in use Other variables to consider
Factors other than design strengthen validity Researcher’s reputation
Randomized controlled trials do not always exist to answer some questions Base decisions on next highest level of evidence Identify research gaps
American Academy of Family Physicians Rating System Level A
Systematic reviews of randomized controlled trials including meta-analyses
Good-quality randomized controlled trials Level B
Good-quality nonrandomized clinical trials Systematic reviews not in Level A Lower-quality randomized controlled trials not in Level A Other types of study: case control studies, clinical cohort studies,
cross sectional studies, retrospective studies, and uncontrolled studies
Level C Evidence-based consensus statements and expert guidelines
Match Resource to Information Need What is the question? How will information be used?
Background vs. Foreground Questions Asking questions about your proposed topic
helps to clarify your knowledge gap Type of question helps to determine which
sources are most likely to have the answers you need
Background Questions
Generally ask who, what, why, where or how about a single concept
Examples: What are the contraindications for the use of
timolol to treat glaucoma? What are the risk factors for glaucoma?
Answers to Background Questions Require general knowledge of disease and
therapeutic processes Resources:
Ovid MEDLINE Basic Search MD Consult Overviews, Review Articles Reference books, monographs – online and
print collections
Foreground Questions
Usually compare two or more concepts – drugs, treatments, tests, prognosis of two groups, harms or benefits of two approaches, etc.
Example: Is latanoprost as effective as travoprost or
bimatoprost in achieving 24-hour control of IOP in patients with POAG?
Answers to Foreground Questions Require precise information about complex
issues Sources should provide current, original
clinical research data OVID MEDLINE – Clinical Queries MD Consult MEDLINE – Limit to Diagnosis,
Treatment, Etiology, Prognosis Point of Care Databases
