This tutorial is intended for any health care practitioner or student who needs a basic introduction to the principles of Evidence-Based Practice. Upon completion of this self-paced tutorial, you will be able to: define Evidence-Based Practice (EBP) identify the parts of a well-built clinical question; identify searching strategies that could improve PubMed searching; and identify key critical appraisal issues that help determine the validity of a study.
This tutorial was developed by staff at Duke University Medical Center Library and the Health Sciences Library at the University of North Carolina at Chapel Hill.
EBP is a Process
Evidence Based Medicine is a process of life-long, problem-based learning.
The process involves:
Converting information needs into focused questions.
Efficiently tracking down the best evidence with which to answer the question.
Critcally appraising the evidence for validity and clinical usefulness.
Applying the results in clinical practice.
Evaluating performance of the evidence in clinical application.
What is Evidence-based Practice and Evidence-based Medicine?
"Evidence-based Medicine (EBM) is the integration of best research evidence with clinical expertise and patient values." --GuyattG,etal. Evidence-BasedMedicineworking Group.Evidence-basedmedicine. Anewapproachtoteaching the practice ofmedicine.JAMA1992; 268:2420-5.
"Evidence based practice (EBP) is the conscientious use of current best evidence in making decisions about patient care." --Sackett, Straus, Richardson, Rosenberg, & Haynes, 2000
the Academy of Medical-Surgical Nurses (AMSN) values evidence-based practice (EBP) as a way to affect best patient care.
Definition: Evidence based practice (EBP) is the conscientious use of current best evidence in making decisions about patient care (Sackett, Straus, Richardson, Rosenberg, & Haynes, 2000).
There is an abundance of definitions of evidence-based practice (EBP). Fortunately, most of them say essentially the same thing. The most well-known definition is that put forth by David Sackett and colleagues: "Evidence-based medicine is the integration of best research evidence with clinical expertise and patient values." (Sackett D et al. Evidence-Based Medicine: How to Practice and Teach EBM, 2nd edition. Churchill Livingstone, Edinburgh, 2000, p.1)
