Why do we need to assess?

The only way we can establish if the care of patients is improved by the application of evidence to practice is to measure the effect of the APPLY stage.

If a practice policy, diagnostic procedure or treatment strategy has changed as a result of finding  (ACQUIRE) and appraising (APPRAISE) the evidence, it is important to look at the consequences of this change. How has it affected the patients? Did it make any difference? Has care improved or declined? Are further changes needed?

Various methods of approaching how you ASSESS the effect of applying EBVM to practice will be outlined in this chapter.
