Critical Appraisal Questions for Evidence-Based Practice: Can I Apply the Results to Practice?

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

Critical Appraisal Questions for Evidence-Based Practice: Are the Results Important?

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 provided the purpose of critical appraisal and overviewed the steps of critical appraisal. In this post, I’ll

What Does “Critical Appraisal” Mean in Evidence-Based Practice?

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

How to Craft a Search Strategy to Answer Clinical Questions

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

Identifying and Building a Clinical Question for Research and Evidence-Based Practice

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

Statistical Conclusion Errors in Hypothesis Testing

You learn about statistical conclusion errors in every basic nursing research class and are expected to understand what these errors mean. Wait! Did I learn about this, you ask? Yes, yes, you did. Remember Type I and Type II errors? Those are statistical conclusion errors. But I’ll tell you that

What Do Confidence Intervals Really Tell You?

Quick recap since talking about confidence intervals is related to p-values: p-values ONLY tell you whether a research result is statistically significant or not based on the

What Do P-Values Really Mean?

This month’s blog theme is nursing research, so I’m discussing the meaning of some statistical concepts to help you interpret the research studies you are reading.  I’m going to talk about several concepts this month that I have found both undergraduate and graduate students struggle to really understand.

What’s the Difference Between Statistical Significance and Clinical Significance?

There are two types of significance used to interpret research studies – statistical significance and clinical significance. They are not the same thing.
