Critical Appraisal of the Evidence Based Practice
Continue of Assignment 0029191, need same writer for all future assignment for next 4 weeks. Question# 1: Read "Evidence-based Practice Step by Step: Critical Appraisal of the Evidence: Part I," and answer the questions in this module: What is the purpose of critical appraisal? Discuss how you would perform critical appraisal of articles selected for your topic(Pressure Ulcer Prevention). Question #2: The article by Fineout-Overholt et al. provides a critical appraisal guide for appraising quantitative studies. Select one quantitative study from the research articles you have identified for your project. Answer three questions listed on the critical appraisal guide created by Fineout-Overholt et al., using the quantitative study you have selected.

Purpose and performing critical appraisal
The aim of critical analysis is to assess its value and worth to practice while also highlighting on flaws (Fineout-Overholt et al., 2010). Also related to this is the rapid critical appraisal, which focuses on determining the level of evidence, how a study was conducted and usefulness to practice (Fineout-Overholt, et al., 2010). Critical appraisal of articles is relevant in evidence-based practice, as the findings are useful in clinical decision making. Similarly, lack of confidence in performing critical appraisal hampers Evidence-based practice (Law& MacDermid, 2008).
In conducting the critical appraisal of an article, it is pertinent to focus on whether the research design is appropriate. The study design should protect against bias whereby RCTs are most likely to be robust while also considering whether they are ethically feasible. Furthermore the related study methods should address the question of biasness either through a random error which affects the study’ precision or systematic bias. Essentially, the research carried out or review of articles should focus on the topic pressure ulcer prevention.
Another area that requires attention is the results of a study. In appraising an article one should look into whether the information presented is objective and clearly presented. This is merely a presentation of the results spelt out in a logical and understandable manner. This can include the characteristics of the study population, and the statistical significance of the data presented under the results section. Overall, the type of evidence should be relevant to the area of pressure ulcer prevention and related to the reasons as to why a study was done.
Part II: Questions related to critical appraisal guide for appraising quantitative studies
Why was the study done?
The study by Moore et al (2011), was carried out to assess the effectiveness of using the 30 degrees tilt in preventing pressure ulcers. However, the authors merely touched on th...
