What is Critical Appraisal?

Critical appraisal is the process of carefully and systematically assessing the outcome of scientific research or evidence to judge its trustworthiness, value and relevance in the particular context.  It allows clinicians to use research evidence reliably and efficiently. Critical appraisal is intended to enhance the healthcare professional’s skill to determine whether the research evidence is true, free of bias, and relevant to their patients.
