Answering Evidence-Based Questions, Step by Step

When looking to answer a clinical question, there are five standard steps you should take:

ASK your question

ACCESS the evidence

APPRAISE the search results critically

APPLY your search findings to your patient's care

ASSESS the effect of the intervention...and start over if necessary

P: Patient or Population

I: Intervention

C: Comparison

O: Outcome
