Summary: "Second edition of the only Johns Hopkins evidence-based practice book heavily adopted as text and supplemental text for nurses. Utilizing the Johns Hopkins Nursing Evidence-Based Practice (EBP) model (Dearholt & Dang, 2012), a guiding practice question was developed: "What are the most efficacious interventions for the management of delirium in adult acute care patients?" An extensive, multi-faceted literature search was conducted: Qualitative research:answers a wide variety of questions related to human responses to actual or potential health problems.The purpose of qualitative research is to describe, explore and explain the health-related phenomena being studied. support recommendations, Level E Theory-based evidence from expert opinion or multiple case reports, Level M Manufacturers recommendations only.

The JHNEBP Model's Appendix A - PET ProcessGuide, supplies you with a checklist to ensure that you have thought through all the steps and have a winning team in place prior to the start. This category of tests can be used when the dependent, or outcome, variable is categorical (nominal), such as the difference between two wound treatments and the healing of the wound (healed versus nonhealed). Meta-synthesis: A systematic approach to the analysis of data across qualitative studies. See their specific Critical Appraisal tools. Evidence level and quality rating: Article title: Number: Author(s): Publication date: Journal: Setting: Sample (composition and size): Does this evidence address my EBP question? See the Welch Library's Expert Searching Guide for more tips and tricks on how to become an expert searcher. Assessing the quality of reports of randomized clinical trials: is blinding necessary? Quantitative studies collect and analyze measurable numerical data. Case control study:A study which involves identifying patients who have the outcome of interest (cases) and patients without the same outcome (controls), and looking back to see if they had the exposure of interest. Johns Hopkins Nursing Evidence-Based Practice Appendix G Individual Evidence Summary Tool . provides logical argument for opinions, C Low quality or major flaws: Expertise is not discernable or is dubious; conclusions The type of study can generally be figured out by looking at three issues: Q2.

The Synthesis Process and Recommendations Tool helps you make sense of the strength of the evidence toward a particular recommendation. The sensitivity and specificity of the new test are compared to that of the gold standard to determine potential usefulness. Literature reviews The Johns Hopkins EBP model uses 3 ratings for the level of scientific research evidence. A confidence interval (CI) can be used to show within which interval the population's mean score will probably fall.
