All month I’ve been discussing the major questions you need to ask when critically appraising a research study. In this post, I’ll review the subquestions you need to ask when determining whether you can apply the results to your patient or patient population. Using Evidence to Make Clinical Decisions The

This month I’m talking about the questions to ask when critically appraising a research study for use in your evidence-based nursing practice. In this post, I’ll address the question of determining if the actual research findings/results are significant and meaningful – What are the Results? (AKA Are the Results Important?) The major
Critical Appraisal Questions for Evidence-Based Practice: Is the Study Necessary and Are the Results Valid?
Critical appraisal skills are essential for the nurse, regardless of role or clinical expertise. I introduced you to the topic of critical appraisal in evidence-based practice (EBP) in the last blog post. I provided the purpose of critical appraisal and overviewed the steps of critical appraisal. In this post, I’ll
Evidence-based practice (EBP) is the deliberate use of the best evidence that is tempered with your clinical expertise and the patient’s preferences and clinical situation. EVERY nurse is responsible for practicing according to the best evidence and research findings – therefore, every nurse needs to understand WHAT EBP is, HOW
This is part two of two posts to foster your ability to systematically frame your questions to craft a search strategy that will offer you the best chance at finding the relevant and valid evidence you need to answer those questions, in the most time-efficient manner possible. The first post
This post is the first of two parts for crafting an efficient search strategy for research studies and for evidence-based practice (EBP) projects. In this post, I’ll provide 4 steps to get you halfway to writing a search strategy. I’ll show you how to identify a clinical question and your knowledge
When reviewing a clinical practice guideline (CPG) or systematic review (SR) with practice recommendations, you’ll notice two scales that are used in conjunction with each practice recommendation offered: a levels of evidence scale and a grading scale. I talked about levels of evidence (LOE) hierarchies in last week’s post. This
In evidence-based practice (EBP), we talk a lot about “Levels of Evidence.” You will see levels of evidence (LOE) ratings on critically appraised topics or synopses of original research, or in the methodology section or evidence table of a clinical practice guideline or systematic review. But what does an LOE
Whether you’ve got a research paper to write or you are looking for best evidence for a specific intervention, you’ve got to search for the evidence to make or back up your arguments, right? Presumably, you’ve answered your background questions and have your foreground question in a PICO format.
When looking for evidence – where should you start? Well at the top of course! At the top of the hierarchy of evidence quality is pre-appraised evidence (Haynes, 2007). If you go through your university or medical library, there are multiple databases to search, such as MEDLINE or CINAHL. You
