The Institute of Medicine (IOM) defines “Evidence-Based
Practice" as a combination of the following three factors:
(1) best research evidence,
(2) best clinical experience, and
(3) consistent with patient values
– (IOM, 2001; http://www.iom.edu/)
1. Research
2. Clinician knowledge
3. Patient needs
Formulating the Question
• Defining a clinical question by the specific
patient and problem lends itself to
effectively finding relevant evidence.
• EBP begins and ends with the patient.
Clinical Question Anatomy
PICO
PICO is a mnemonic that helps one
remember the key components of a well
focused question.
PICO
• P = Patient, Population or Problem
• I = Intervention, Prognostic Factor, or Exposure
• C = Comparison (if there is one)
• O = Outcome
Our clinical question
• Is there evidence to support school based
obesity prevention programs.
PICO
•
•
•
•
P = School age children
I = School based program
C = None (or community program)
O = Reduced obesity
