The EBM Process: Formulating a Clinical Question
Types of Clinical Questions
There are basically two types of clinical questions:
Background: Questions often asked early on when learning about
a subject. These questions usually relate to background information.
An example: What is the physiology
of the kidney?
Foreground: Questions asked when the questioner has more experience
and knowledge about a subject area. An example: Are ACE inhibitors an efficacious treatment of diabetic
patients with microabluminurea?
Generally when a student progresses with a subject and gains
more experience with it, his or her questions transition from more background
to more foreground questions.
It is important for physicians to realize what kind of question
they are asking because this will influence what type of resource
will be able to help them find the answer.
For example, if a medical student is just starting to learn about
the kidney, she will likely be asking background questions that
can best be answered by consulting a text book or review article.
An Internal Medicine intern will likely be asking more foreground
questions and will need to look for systematic review articles in
internal medicine journals. A nephrology fellow will likely be asking
almost exclusively foreground questions and may need to look at
articles in the literature reporting the results of individual randomized
controlled trials or even case series.
