Effective Database Searching: PICO Framework

This guide to key library databases helps you decide which databases to use and assists you in searching them more effectively.

PICO Framework

 

Format a well-focused clinical question using the elements of the PICO framework to facilitate creating an effective search strategy1:

P = Patient, Population or Problem

I = Intervention or Exposure

C = Comparison or Control (if applicable)

O = Outcome(s)

Example of a therapy-type question: In patients with osteoarthritis of the knee, is physical therapy more effective than medication in relieving pain?

                                                                                                                                        I                                                        C                               O

*Use the PICO formatting tool for additional help in formulating your question.*
