Research Utilization and Evidence-Based Practice
Evidence-based practice...quality filtering...retrieving clinically relevant studies...there are several definitions of what is meant by the term "evidence-based." One of the most frequently cited is:
"the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients."*
Evidence-based nursing expands the above definition to include "patient preferences" and "clinical expertise" as sources of evidence.**
Only a small percentage of the published literature contains evidence that is ready for clinical application. And it is estimated that only 1 in 5000 ideas eventually makes it through all of the trials and the research stages to produce evidence with clinical outcomes.*** While the best practitioners have always followed this model, evidence-based practice is a formal approach that takes advantage of the ability to search electronic databases to retrieve methodologically sound studies.
