Identify main concepts

Use 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

type of question/type of study

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.
