Evidence-Based Medicine

This page has resources and information about Evidence-Based Medicine (EBM), for students.

About EBM

The EBM process is contained in 4 steps:

  1. Ask
  2. Acquire
  3. Apraise
  4. Practice

This process is further clarified and defined by the PICO process:

Patient/Problem

What are the important characteristics of this patient?

  • Primary Problem
  • Patient's main concern or chief complaint
  • Disease or health status
  • Age, Race, Sex, Previous ailments, current medications

Intervention

It is important to identify what you plan to do for that patient. This may include the use of a specific diagnostic test, treatment, adjunctive therapy, medication or the recommendation to the patient to use a product or procedure. The intervention is the main consideration for that patient or client.

Comparison

What  is the main alternative you are considering? The Comparison is the only optional component in the PICO question. One may only look at the Intervention without exploring alternatives, and in some cases, there may not be an alternative

Outcome

This specifies the result(s) of what you plan to accomplish, improve or affect and should be measurable. Outcomes may consist of:

  1. Relieving or eliminating specific symptoms
  2. Improving or maintaining function
  3. Enhancing esthetics.
