What is PICO?
PICO is a mnemonic used to describe the four elements of a good clinical foreground question:
P = Population/Patient/Problem - How would I describe the problem or a group of patients similar to mine?
I = Intervention - What main intervention, prognostic factor or exposure am I considering?
C = Comparison - Is there an alternative to compare with the intervention?
O = Outcome - What do I hope to accomplish, measure, improve or affect?
