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
Ask a question - Converting the need for information (about prevention, diagnosis, prognosis, therapy, causation, etc) into an answerable question
Find information/evidence to answer question - Finding the best evidence with which to answer that question
Critically appraise the information/evidence - Critically appraising that evidence for its validity (closeness to the truth), impact (size of the effect), and applicability (usefulness in our clinical practice)
Integrate evidence with clinical expertise and patient’s preferences- Integrating critical appraisal with clinical expertise and patient's unique biology, values, and circumstances
Evaluate- Evaluating effectiveness and efficiency in executing Steps 1-4 and seeking ways to improve them both for next time
