What is EBM?

Steps to EBP

  1. Ask a question
    Converting the need for information (about prevention, diagnosis, prognosis, therapy, causation, etc) into an answerable question

  2. Search and find information/evidence to answer question
    Tracking down the best evidence with which to answer that question 

  3. 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) 

  4. Implement and 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 

  5. Evaluate
    Evaluating our effectiveness and efficiency in executing Steps 1-4 and seeking ways to improve them both for next time

This should be an ongoing process in clinical practice.
