Critical appraisal is currently a key component included in the training and continuing professional development of all health professionals like nurses in various settings (Burls, 2009). Critical appraisal allows a nurse to judge the validity, reliability and applicability of results of any clinical research while applying it to practice (Burls, 2009). This is because, the process includes intrinsic factors of research like study design, methods, results, etc,to analyze the value of the study. Critical appraisal is a very essential component of evidence based practice which is gaining momentum. The process of critical appraisal involves identifying the appropriateness of the study for the purpose of evidence based practice, ascertaining whether the studies have been conducted in a way which makes the results sensible, making sense of the results by analyzing the methodology of analysis and also understanding the meaning of the results in the context of decision making (Burls, 2009). One of the main challenges to implementation of critical appraisal for evidence based practice is lack of evidence seeking behaviour amongst many clinicians, poor attitude towards evidence based practice, need for appropriate technical knowledge of research design and statistics which are difficult to acquire and lack of time (Brice and Booth, 2005).
