Background questions:
Are there elements of the question which require basic (background) research? Is there a gap in the clinician's/researcher's knowledge about specific elements of the question?
Background questions are typically answered with textbooks, reference texts, summary/review articles, and point-of-care tools.
Background question example:
Asian-American adult female with type 2 diabetes mellitus requests alternatives to insulin treatment.
Foreground question:
Foreground questions combine predetermined elements of the clinical problem to acquire specific knowledge. They are more complex and specific than background questions.
Foreground questions combine the Patient/Population/Problem and the Intervention and the Control treatment and the desired Outcome into a PICO format.

Patient/Population/ Problem |
Intervention | Control | Outcome Measure | Level of Evidence |
Therapeutic/ Treatment |
Disease or condition | Therapeutic measures: Exercise, medication, surgical, life style change | Standard of care, additional intervention, placebo, no control | Measurable improvement in impairment/disease factors | Randomized Control Trial (RCT) |
Prevention | Risk factors, Medical history | Preventative measures | Alternative preventative measures or no control | Measurable improvement in impairment/disease factors | RCT or Prospective study |
