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
