NRS307: Nursing Care of the Adult Population I: Evidence Based Practice

What is Evidence-Based Practice?

Evidence-Based Practice (EBP): "EBP is a conscientious, problem-solving approach to clinical practice that incorporates the best evidence from well-designed studies, patient values and preferences, and a clinician's expertise in making decisions about a patient's care" (, 2020). 

Difference Between EBP & Research

There is a common misconception that EBP and research are one in the same. Not true! While there are similarities, one of the fundamental differences lies in their purpose:

Research: To generate new knowledge or validate existing knowledge based on theory.

Evidence-Based Practice: To use best available evidence to make informed patient-care decisions.

In contrast, the purpose of EBP isn’t about developing new knowledge or validating existing knowledge—it’s about translating the evidence and applying it to clinical practice and decision-making. Most of the best evidence stems from research, but EBP goes beyond research and includes the clinical expertise of the clinician and healthcare teams, as well as patient preferences and values.
