What is critical appraisal?

"Critical appraisal skills enable you to assess the trustworthiness, relevance and results of published papers so that you can decide if they are believable and useful."  

(http://www.casp-uk.net/criticalappraisal)

Critical appraisal tools/worksheets help you appraise the reliability, importance and applicability of clinical evidence.

Critical appraisal is the systematic evaluation of clinical research papers in order to establish:

  1. Does this study address a clearly focused question?
  2. Did the study use valid methods to address this question?
  3. Are the valid results of this study important?
  4. Are these valid, important results applicable to my patient or population?
