Skip to Main ContentUse the mnemonic device PICO to identify the main concepts from the patient's case:
PICO for patient case example:
P | Patient, population, and/or problem | Patient xyz |
I | Intervention, exposure, or prognostic factor | Intervention xyz |
C | Comparison or control | Comparison (maybe) |
O | Outcome | Outcome xyz |
Identifying the type of question you are trying to answer will help you focus/phrase your PICO question and determine the best study design to answer that question.
