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
