Appraising the Literature

For the DNP-prepared nurse, it is important to hone skills related to reviewing and evaluating research literature to implement evidence-based practices. As you examine epidemiological research, in particular, it is essential to ask, “What are the strengths and weakness of the research method(s)? Are the data analysis and interpretation sound? Is there any evidence of bias?” This Discussion provides you and your colleagues valuable practice in critically analyzing research literature.

To prepare:

• With      this week’s Learning Resources in mind, reflect on the importance of      analyzing epidemiological research studies.
• Critically      appraise the Oppenheimer (2010) and Elliott, Smith, Penny, Smith and      Chambers (1999) articles presented in the Learning Resources using      Appendix A in Epidemiology for Public Health Practice as a guide.
• Determine      the strengths and weaknesses of the research methods and data analysis of      each study.
• Ask      yourself, “Is any bias evident in either study? What did the researchers      do to control for potential bias?”
• Finally,      consider the importance of data interpretation in epidemiologic literature      and the issues that may arise if potential confounding factors are not      considered.

By tomorrow 04/05/2018 3pm, write a minimum of 550 words in APA format with at least 3 scholarly references from the list of required readings below. Include the level one headings as numbered below”

Post a cohesive scholarly response that addresses the following:

1) Appraise the Oppenheimer (2010) and Elliott et al. (1999) articles, summarizing the strengths and weaknesses of each study (see attached files for those articles).

2) Analyze potential sources of bias in each study and suggest strategies for minimizing bias.

3) Suggest possible confounding variables that may have influenced the results of each study.

Required Readings

Chapter 10, “Data Interpretation Issues”

Chapter 15, “Social, Behavioral, and Psychosocial Epidemiology”

Appendix A – Guide to the Critical Appraisal of an Epidemiologic/Public Health Research Article

In Chapter 10, the authors describe issues related to data interpretation and address the main types of research errors that need to be considered when conducting epidemiologic research, as well as when analyzing published results. It also presents techniques for reducing bias. Chapter 15 features psychosocial, behavioral, and social epidemiology. Appendix A includes criteria to consider when reading an empirical journal article.

This article describes an early epidemiologic study on chronic pain. Carefully review this article noting the structure of the research design, assessment and data collection, and analysis strategies. You will refer to this article for Discussion 2. (see attached file)

Oppenheimer, G. M. (2010). Framingham Heart Study: The first 20 years. Progress in Cardiovascular Diseases, 53(1), 55–61.

The Framingham Heart Study is a landmark epidemiologic study that began in the 1940s. The author of this article reviews the history of the Framingham Heart Study and its contribution to population health. As you read this article, consider any sources of bias or potential conflict of interest. You will refer to this article for Discussion 2. (See attached file).

In 1965, Austin Bradford Hill worked on a paper that has become a standard in public health and epidemiologic study about how to make decisions based on epidemiologic evidence. Hill put forth strategies for inferring causation and stressed the need for considering costs and benefits when planning health-promoting interventions. Review this article, which examines how Hill’s strategies are often misused or misinterpreted.
