The American Journal of Nursing uses a concise definition of evidence-based practice, “Evidence-based practice (EBP) is a problem-solving approach to the delivery of healthcare that integrates the best evidence from studies and patient care data with clinician expertise and patient preferences and values.” A pyramid is often used to depict the levels of “best evidence” with the strongest evidence at the top. The pyramid also represents the quantity of evidence forms in the literature. For example, there typically are fewer meta-analyses in the literature than cohort studies.
