Converting the need for information (about prevention, diagnosis, prognosis, therapy, causation, etc) into an answerable question
Find information/evidence to answer question
Tracking down 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 appraised evidence with own clinical expertise and patient’s preferences
Integrating the critical appraisal with our clinical expertise and with our patient's unique biology, values and circumstances
