Evidence-Based Practice Research

Evidence based nursing is a part of the larger scope of evidence based practice.  One of the most common defintions of evidence based practice comes from Dr. David Sackett. He describes EBP as:

"...the conscientious, explicit and judicious use of current best evidence in making decisions about the care of the individual patient. It means integrating individual clinical expertise with the best available external clinical evidence from systematic research."
