Evidence
Based Practice

MGH EBP Resources


The Hopkins process for EBP relies on three elements, Practice Question, Evidence, and Translation, and is known as the PET Process.

To develop a practice question, we use the P-I-C-O method.
P = patient, population, problem
I = Intervention
C = Comparison
O = Outcome

PICO question example:
In critical care patients (P) are Allevyn foam dressings (I) more effective than Mepilex foam dressings (C) at preventing sacral pressure ulcers (O)?
