Clinical practice problems surround us. Some typical questions we might ask are:
Clearly defining the specific problem will help focus your search to find the best available evidence.
These questions are used to gain a better understanding about the health condition and to identify search terms.. The essential components of background questions are:
1) A question root (who, what, where, when, how, why)
2) A disorder, test, treatment
Textbooks, monographs, or web resources are good sources of answers to background questions.
These are designed to ask about specific information for clinical decision-making and thus focus your search. Foreground questions are often asked in a format called PICO::
1) Patient and/or Problem
3) Comparison intervention (if relevant)
4) Clinical Outcomes.
An example of a PICO question is:
Finding relevant journal articles, using bibliographic databases such as PubMed, CINAHL or Web of Science will usually answer foreground questions.
Another way to frame the question is to use the templates developed by Melnyk and Fineout-Overholt.
