Evidence-Based Nursing: Evidence Application

What is Evidence Application?

The fourth step, that of evidence application, involves the integration of relevant evidence with clinical experience. A decision is made regarding whether the evidence that has been obtained is relevant and valid research to be applied to the question that one seeks to answer.  The effectiveness of a therapeutic intervention, based on the evidence, is determined by assessing the internal validity and external validity of a given study.

     -       Internal validity:  Is it a high quality study in terms of its methods (does it measure what it was intended to measure)?

     -       External validity:  Is the population and setting of the study similar to that of the one evaluated in the clinical question?

When these questions are answered, the evidence is applied by making a practice decision that integrates evidence, clinical expertise, and patient factors and preferences.  Usually a model of evidence based practice is used to apply research findings in nursing practice.
