Finding the evidence is the second step in the five steps of evidence-based practice.

It is important when searching for evidence that search terms are referred back to your original PICO question. The process of finding evidence therefore follow three key steps:

  1. Identify terms to fit your PICO question
  2. Look for secondary sources
  3. Search for primary sources
