PICOTT is a mnemonic used to describe elements of a good clinical foreground question.
The PICOTT model is used in evidence-based practice to assist in formulation of searchable clinical questions.
PICO is a good framework to help clarify your (clinical, review, or research) question.
P - Patient, Population or Problem: What are the important characteristics of the patients &/or problem?
I - Intervention: What you plan to do for the patient or problem?
C - Comparison: What, if anything, is the alternative to the intervention?
O - Outcome: What is the outcome that you would like to measure?
