Using PICO to Frame Clinical Questions
To use evidence-based practice, you need a clear idea of the question you would like to answer. The PICO criteria can help you formulate a clinical question and guide your search for Evidence, helping you find the best evidence in a quicker, more efficient manner.
P | Patient or Problem | How would you describe the patient? What issue are they experiencing? |
I | Intervention | What would you like to do to help the patient? |
C | Comparison | What would be the alternative to the intervention you selected? |
O | Outcome | By doing the intervention, what do you hope to accomplish? |
PICO can also help you to identify keywords to use in CINAHL and PubMed. You don't want to use the entire clinical question as your search terms. Pull out the most important words to optimize your search results.
