Using PICO can help you define and narrow your research question so that it is specific.
P - Patient, population, or problem
I - Intervention
C - Comparison or Control
O - Outcome
Think about whether your question is relevant to practitioners, and whether the answer will help people (doctors, patients, nurses) make better informed health care decisions.
Before beginning, make sure your research is original.
Before beginning, make sure a review has not already addressed your question.
Do a thorough search in the following databases; you can also consult your librarian for guidance. Make sure you check for both published reviews and registered protocols (to see if a review is in progress).
The Joanna Briggs Institute should also be searched for reviews that have been done or are in process. Gumberg does not currently provide access; contact your librarian for assistance.
