A PICO or PICOT question is a structure way of asking a clinical question. It is an EBP method for developing a research question.
P - Patient / Population
I - Intervention / Indicator
C - Comparison
O - Outcome
T - Time
Thinking in these terms can help you narrow down your question to something actionable and aids in the development of search terms and inclusion/exclusion criteria.
