NUR 3300 - Foundations of Research and Evidence-Based Practice: Evidence Levels/Research and Review Types

Librarian-recommended resources to help you find the best available evidence.

Levels of Evidence and Study Designs

Levels of evidence vary somewhat depending on the source you use. Two of the most commonly used levels of evidence in Nursing are from authors Melnyk and Fineout-Overholt and the Johns Hopkins Evidence-Based Practice Model, but they are not the only options that exist.  Therefore, when indicating the level of evidence in a synthesis table or written narrative, ALWAYS clearly indicate whose evidence levels or grading system you are using.
