Evidence-based practice uses the PICO model for formulating a searchable question.
PICO is a mnemonic used to describe the four elements of a good clinical foreground question:
P = Population/Problem
How would I describe the problem or a group of patients similar to mine?
I = Intervention
What main intervention, prognostic factor or exposure am I considering?
C = Comparison
Is there an alternative to compare with the intervention?
O = Outcome
What do I hope to accomplish, measure, improve or affect?
Evidence Based Medicine is a process of life-long, problem-based learning. The process involves:
♦ Converting information needs into focused questions.
♦ Efficiently tracking down the best evidence with which to answer the question.
♦ Critically appraising the evidence for validity and clinical usefulness.
♦ Applying the results in clinical practice.
♦ Evaluating performance of the evidence in clinical application.
