PICO Question Examples

Models based on evidence employ a systematic approach to formulate a question, identify, assess, evaluate, and iterate as necessary. The PICO (T) framework consists of the following elements: Problem/Patient/Population, Intervention/Indicator, Comparison, Outcome, and (optionally) Time element or Type of Study.

The question above encompasses the following PICO elements:
P (Problem or Patient or Population): hospital-acquired infection
I (Intervention/Indicator): hand washing
