Why Evidence Based Practice?
There is a substantial gap between the best research evidence and clinical practice with potentially serious health consequences for patients. Key reasons for the research-practice gap include lack of time and skills needed for finding and appraising the evidence. Evidence based practice helps bridge that gap by providing strategies that facilitate finding and appraising research, and resources that pre-filter and synthesize research to make the process more efficient.

It is recommended that you formulate your question using the PICO (or PICOT) concept to search for quantitative studies. The PICO format provides a consistent, systematic way to identify the components of a clinical issue.
Critical appraisal is the systematic evaluation of clinical research papers in order to establish:
If the answer to any of these questions is “no”, you can save yourself the trouble of reading the rest of it.
