EBP Research Process

Ask a Question

  • Get to know your topic
  • Ask yourself the 5 W's and H: Who, What, Where, When, Why, and How?  (Who are the stakeholders? What is the issue/problem/concern/innovation? Where and When will it/does it occur?  Why is it important?  How will you propose to address it?)
  • Do background research to make sure you have a solid foundation 
  • Create a research question to guide your search

Acquire Evidence

Appraise the Evidence

  • Critically appraise the evidence/research you found: what methodologies were used?  How was the data analyzed and reported?  Are the conclusions supported by the data?

Implement

  • Consider what the evidence means in your situation, related to your stakeholders and their needs, and how it may be best implemented

Evaluate/Assess

  • How did it work?  Did you see results that created the outcomes you were trying to achieve?  Do you need to adjust the implementation?  Do you need a different solution?
