PICO Search Strategy

PICO is a mnemomic device used to identify and define the scope of your research question.

P is for Patient, Population, or Problem (i.e. a disease or condition)

I  is for Intervention (e.g. therapy, procedure, drug, exposure, test, strategy) 

C is for Comparison (i.e. compared to an alternative intervention or an experimental control)

O is for Outcome (i.e. the consequence, effect or improvement of interest and the measurement thereof)

Optional

T is for Type of question (e.g. is your question about therapy; diagnosis; prognosis; etiology; harms; prevention) 

T is for Type of research study most likely to provide answers (e.g. systematic review; randomized controlled trial (RCT); longitudinal study; qualitative study)

Search Tips

• use backgrounds sources from encyclopedias and dictionaries 
• search in scholarly databases such as CINAHL Ultimate for peer-reviewed articles
• search two or three parts of your PICO at a time - not every article will cover all parts of your PICO
