Evidence Based Practice: Overview

What is Evidence Based Practice?

Evidence-based practice is the conscientious use of current best evidence in making decisions about patient care. -David L Sackett, W Scott Richardson, William Rosenberg, Brian Haynes, Evidence Based Medicine--How to Practice and Teach EBM, 2000.

Evidence-based Practice is a problem solving approach to clinical practice that integrates:

  • A systematic search for and critical appraisal of the most relevant evidence to answer a burning clinical question
  • One's own clinical expertise
  • Patient preferences and values.

-Bernadette Mazurek Melnyk, Ellen Fineout-Overholt, Evidence-Based Practice in Nursing & Healthcare: a Guide to Best Practice, 2005.
