Q. My professor said we have to form a PICO question and then find the answer. How do you do that?

Here are two sources that explain how to formulate a PICO question:

Developing a Well-Built Clinical Question

Asking Better Clinical Questions

Once you have the question formed, you can then search for the answer in a database. A good database to use for this is PubMed Clinical Queries since it is designed to work with your question. It works well for handheld and smartphone users with links to search tools and full-text articles available from the Health Sciences Library.

Other important medical databases to use for clinically-based answers are:

The Cochrane Library

TRIP Database (use the PICO search function)
