In the health sciences, a research question is often formulated using the PICOT framework. A PICOT question is a research question that contains certain elements within the question.
These are the 5 components of a PICOT question:
P: Patient
I: Intervention, exposure, prognosis factor
C: Comparison
O: Outcome Some instructors also add
T: Time*
(*not always required)
Using PICO is important for evidence-based practice. A well-constructed PICOT question helps find the best evidence available to influence practice.
Templates for asking PICOT Questions
INTERVENTION
In __________________(P), how does__________________(I) compared to _________________(C) affect ______________(O) within ___________(T)?
THERAPY
In________________(P), what is the effect of _______________(I) compared to_____________ (C) on______________(O) within ___________(T)?
PROGNOSIS/PREDICTION
In ____________(P), how does ________________ (I) compared to____________(C) influence ______________(O) over ____________ (T)?
DIAGNOSIS OR DIAGNOSTIC TEST
In _________________(P) are/is ________________(I) compared with ______________(C) more accurate in diagnosing ________________ (O)?
ETIOLOGY
Are_________________(P), who have________________(I) compared with those without __________________(C) at__________ risk for/of ______________(O) over_____________(T)?
MEANING
How do _______________(P ) with _________________(I) perceive__________________(O) during ___________(T)?
So a research question about compression stockings could be:
In patients with a history of DVT, does the use of compression stockings decrease the chances of developing clots compared to patients not wearing compression stockings in a 6 month period?
