The PICO Framework is a useful tool to help you form a question that clearly articulates the major topics in your search. This framework is favored among evidence-based practice (EBP) researchers since the structure can accommodate most clinical research question types (therapy, prevention, diagnosis, prognosis, etiology, etc.)
PICO stands for:
P | I | C | O |
Patient/Population/Problem | Intervention | Comparison | Outcome |
Age, condition, gender, geographic location or specific characteristics | Treatment, prognostic factor, management strategy, diagnostic test or exposure | Control or alternative management strategy you would like to compare to the intervention |
Patient-relevant consequences of the intervention |
Examples:
There are also other question frameworks you can use depending on your question. These include: CoCoPop, PEO, PFO, SPICE and SPIDER.
