PICO Sample Searches

When constructing a research question, the PICO format is widely used for questions of therapy.

Frame your question to include:


P (patient/problem) hospital infection
I (intervention/indicator) handwashing
C (comparison) no handwashing; other solution; masks
O (outcome of interest) reduced infection


Including the PICO elements in your question will help you to approach the literature search in a focused way as a first step to gathering evidence. 

The sample searches below demonstrate PICO questions and a search strategy.
