Movement Science: Evidence Based Research (PICO)

Evidence Based Medicine

EBM is "the conscientious use of current best evidence in making clinical decisions about patient care". This original definition is attributed to this article by Sackett, et al.

Step One: Ask a Clinical Question

Using the PICO format can be instructive!

Patient Population
Intervention
Comparison Intervention
Outcome

Types of Questions: Etiology, Diagnostic, Prevention, Prognosis/Prediction, Therapy, Qualitative

Prevention Example:
For patients with systolic heart failure (P) do exercise programs (I) reduce the future risk of hospital admission due to heart failure (O) compared with patients without exercise programs (C)?
Therapy Example:
In patients with chronic wounds (P) what is the effect of topical negative pressure (TNP) (I) on promoting healing (O) compared with traditional moisturized gauze (C) dressing?

PICO Continued

Etiology: Are ____(P), who have ____ (I) at ____(increased/decreased)risk for/of_____(O) compared with____(P) with/without_____(C)?
