Evidence Based Practice: What is it?

What is Evidence Based Practice?  What does it have to do with you?  How can you use Bethel Library resources for EBP?

EPB is basically a method for making clinical decisions or answering clinical questions using the best available evidence in coordination with the expertise of the clinician and the preferences and values of the patient.* 

Clinical research questions are often framed using the abbreviation PICO. The elements of a PICO question are:

P:
What is the Patient population being studied?.

I:
What is the Intervention being studied or recommended?

C:
What Comparison Interventions exist?

O:
What is the desired patient outcome?

Thinking about your clinical research question in terms of its PICO components can be a helpful way to begin the literature review process.
