PICO Questions

PICO is an acronym to help researchers create focused, clinical questions. Each part of the PICO is a key concept in a clinical question

- Patient/Problem/Population: How would you describe the patient or problem? This could include gender, age, disease, etc.

- Intervention: What change or difference are you applying? Interventions could include medications, surgeries, 

- Comparison: What are you comparing your intervention to? This could be an alternative intervention or even a placebo. The comparison might not be necessary in all PICO questions.

- Outcome: What are you trying to accomplish or measure? 

Using parts of the PICO question as search keywords can help build a quality search query to find the best evidence-based information.
