Critical appraisal

Posted on September 6, by Robert Will Tutorials and Fundamentals Critical appraisal of scientific literature is a necessary skill for healthcare students. Database searching is a skill in itself, but will not be covered in this blog. Critical appraisal of a journal article is a literary and scientific systematic dissection in an attempt to assign merit to the conclusions of an article.

Ideally, an article will be able to undergo scrutiny and retain its findings as valid. The specific questions used to assess validity change slightly with different study designs Critical appraisal article types. However, in an attempt to provide a generalized checklist, no specific subtype of article has been chosen.

Rather, the 20 questions below should be used as a quick reference to appraise any journal article. Critical appraisal of…the Introduction Does the article attempt to answer the same question as your clinical question? Is the article recently published within 5 years or is it seminal i.

Is the journal peer-reviewed? Do the authors present a hypothesis? Critical appraisal of…the Methods Is the study design valid for your question? Are both inclusion and exclusion criteria described?

I believe some of these items are weighted heavier than others i. However, without taking this list through rigorous testing, I cannot assign a weight to them.
