Research methodology and conceptual frameworks.
For this assignment, you will select an appropriate appraisal tool (cohort studies, case control studies, systematic reviews, qualitative studies, et cetera) to analyze three published journal articles related to the topic of hypertension in the African American population. This assignment will help you to develop critical and analytical skills by methodically appraising the merits of published research. A sound appraisal will gather the most reliable information concerning a health problem, relevant research methodology, and conceptual frameworks.
In addition, you will write a brief summary on how you will use the information from these appraised journal articles in your proposed intervention study and determine how the interpretation of the research results described in the articles are affected by information bias, selection bias, and confounding.
Instructions
- Analyze three published journal articles related to the topic you selected for the assignment in Unit 3.
- Write a brief summary of how you will use the information from these appraised journal articles in your proposed intervention study and how the interpretation of the research results described in the articles are affected by information bias, selection bias, and confounding.
Document Format and Length
- Use the Appraisal of Literature Template, attached.
- Your appraisal document should be 2–4 pages in length.
Appraisal Requirements
The requirements outlined below correspond to the grading criteria in the Critical Appraisal of Published Literature Scoring Guide, so be sure to address each point. Read the performance-level descriptions for each criterion to see how your work will be assessed.
- Analyze research articles related to an epidemiological issue, using the appropriate appraisal tools.
- Summarize how information from appraised journal articles could be integrated into a proposed intervention study.
- Identify the public health data that highlight the severity and magnitude of a selected epidemiological issue.
- Discuss how interpretation of results from scholarly articles are affected by information bias, selection bias, and confounding.
- Write clearly and concisely in a logically coherent and appropriate form and style.
Submission Requirements
Proofread your assignment, before you submit it, to minimize errors that could distract readers and make it more difficult for them to focus on the substance of your appraisal.
Requirements: 2-4 pages- template attached
Answer preview
The articles are pretty informative on the subject of hypertension among African Americans. This information will be helpful in my proposal in several ways. The first article is very informative regarding the role of race in the fight against hypertension. The article enlightens readers on the various aspects of hypertension management, including counseling, adherence to medication, and confidence in self-management. Additionally, the second article enlightens on the risk factors, including anemia, diabetes, dyslipidemia, and cardiovascular and renal comorbidities. The third article mainly focuses on the prevalence of potentially inappropriate medication. It concludes that patients suffering from multiple chronic conditions are highly likely to receive prescriptions that may lead to harmful drug-drug interactions. These articles will be useful in guiding my research questions.
However, the interpretation of these results is also affected by information bias, selection bias, and confounding. In article one, for instance, the results are affected by information bias since the responses collected from participants were based on self-report. In this case, there was a probability of failure to recall about diagnosis or counseling by participants. Additionally, since the sample included all individuals who have ever been told that they had hypertension, and those who did not have it at the moment were not included, the estimation of patient adherence or provider intervention may have been overestimated or underestimated due to information bias. With regard to sampling, the third study used a convenient sample, while the second study was conducted in a single urban hospital, and the first study used a sample of all who had been informed of having hypertension.
