Framing Your Clinical Question

To help keep your question focused and relevant, try using the PICO framework:

  • Population - How are you defining the group? What are their characteristics? Consider diagnosis, age, severity, etc.
  • Intervention - What treatment, screening, assessment, etc. are you considering?
  • Comparison - What is your main alternative to the intervention? (sometimes there isn't one)
  • Outcome - What do you want to improve, measure, achieve?

Before gathering evidence, consider additional/alternative keywords for each part of your PICO question.
