Evidence-Based Practice: Critical Appraisal of Qualitative Evidence


· Critical Appraisal

Note: Remember to adhere to the requirements for initial discussion postings and responses addressed in the Discussions section of the Course Policies and Expectations presentation.
In the article, “Evidence-Based Practice: Critical Appraisal of Qualitative Evidence,” the author asserts that all qualitative critical appraisals base their criteria on three primary questions: 1) Are the study findings valid? 2) What were the results of the study? and 3) Will the results help me in caring for my patients? Each of these three primary questions is addressed in its own table in the article, Tables 2, 3, and 4 respectively.
In your initial post, select a sub-question from each table and use that sub-question as a foundation for the discussion.
1. Choose and list a sub-question from Table 2. Sub-questions to Further Answer, Are the Study Findings Valid? and address these questions in relation to it.
1. In appraising the validity of a qualitative study, how does the sub-question you chose help to determine the validity of the study?
1. What would you look for in the study to answer the sub-question?
. Choose and list a sub-question from Table 3. Sub-questions to Further Answer, What Were the Results of the Study? and address these questions in relation to it.
2. For appraising the quality of the results of a study, what does the sub-question you chose ask the appraiser to determine?
2. How will answering this sub-question add value to the critical appraisal of a qualitative study?
. Choose and list a sub-question from Table 4. Sub-questions to Further Answer, Will the Results Help Me in Caring for My Patients? and address these questions in relation to it.
3. In terms of caring for your patients, how will answering the sub-question you chose determine whether or not the results will help you do this?
3. What other sub-question would be most beneficial to appraising the results of the qualitative study as they relate to patient care?


Evidence-based practice involves finding the best research evidence to support an intervention, which is integrated with patient preferences and values and professional expertise, and then implemented. Once you have searched and found relevant and timely research studies, the next step is to evaluate the quality of their methods, design, and other elements and to explore the application of the evidence they provide in different scenarios and settings. It is of paramount importance to correctly identify the type of research methods used in the study—quantitative or qualitative, or a mixture of both—and to evaluate the study to ensure those methods are high-quality, valid, reliable, and accurate. Consequently, doctoral professionals must develop a working knowledge of how to identify and critically appraise specific, important elements of both quantitative and qualitative research studies. Rapid critical appraisal tools assist in developing this skill.


· Review the following two quantitative and qualitative studies. You will describe the key elements of each study and complete a critical appraisal of each.
