NURS 8201 Week 7 Discussion Use of Regression Analysis in Clinical Practice ANSWERS
Week 7: Quantitative Analysis and Interpretation: Regression
How might you predict future events in your practice? Why is it important, as a future DNP-prepared nurse, to consider such future events?
For a DNP-prepared nurse, future predictions might lead to better patient outcomes and care. Therefore, analyzing factors to predict or evaluate can assist in transforming nursing practice or healthcare delivery. The “statistical procedure most commonly used for prediction is regression analysis” (Gray & Grove, 2020).
This week, you will examine the application of linear regression. You will analyze the strengths and weaknesses of the findings in a research study determined with linear regression, as well as explore alternatives to strengthen the aims of the study. You will also begin work on an Article Critique Assignment. While this Assignment is not due until Week 10, you are encouraged to begin this Assignment this week.

Discussion: Use of Regression Analysis in Clinical Practice
Regression analysis provides the researcher with an opportunity to predict and explore future outcomes. Whether it is to determine prevention methods, promote opportunities for learning, or propose new treatments, looking towards the future can have a significant impact on patient care and sustained positive patient outcomes.
This week, you explore regression analysis, paying particular attention to linear regression. Linear regression is used to “estimate the value of a dependent variable based on the value of an independent variable” (Gray & Grove, 2020). In your Discussion, you will apply your understanding of this statistical technique as it concerns use in a research study.

Week 7 Discussion
Assignment: Article Critique
DNP graduates are expected to apply research findings and integrate nursing science into evidence-based practice. To develop your skills in this high level of nursing practice, you will analyze the strengths and weaknesses of a research study over the next several weeks using the concepts presented throughout the course.

- A brief, 1- to 2-paragraph overview of the study that you selected.
- An explanation of two to three strengths of the study and support for your selection (i.e., why is this a strength?). Be specific.
- An explanation of two to three weaknesses of the study and support for your selection (i.e., why is this a weakness?). Be specific.
- Note: The strengths and weaknesses that you identified should be in relation to design, sampling, data collection, statistical analysis, results, and discussion of the study that you selected.
- An explanation of proposed changes that you would recommend to improve the quality of the study, capitalizing on the strengths and improving on the weaknesses that you identified in the study. Be specific and provide examples.
- A final summary of the implications of this study for nursing practice.
The purpose of the analysis is to help you develop a deeper understanding of the research process, to inspire you to think critically and deeply about research on a specific topic, and to strengthen your ability to integrate research findings into evidence-based nursing practice. This Assignment also gives you practice in analyzing the research literature, which will support you when you begin your DNP project. Before you proceed, please review the rubric for this Assignment. Keep in mind that you will be working on your article critique throughout Weeks 8 through 10 with your critique due by Day 7 of Week 10.
The Assignment: (5–7 pages)
- Select a research article from the body of literature that you have reviewed related to the practice gap you have identified and for which you will develop for your DNP Project.
- Review the various quantitative research designs presented in the textbook readings and research articles.
- Consider the research design used in your selected article. Ask yourself the following questions.
- Is the design appropriate for the study? Why or why not?
- Would a different design provide better results? Why or why not?

Logistic Regression in Nursing Practice
The article I chose to examine and analyze this week is “Prediction of influenza vaccination outcome by neural networks and logistic regression.”
Tritica- Majnaric,L., Zekic-Susac, M., Sarlija, N., & Vitale, B. (2010).Prediction of influenza vaccination outcome by neural networks and logistic regression. Journal of Biomedical Informatics, 43(5), 774-781
Post your critical analysis of the article as outlined above
The critical issue with influenza vaccination is to foretell vaccine efficacy. The study presented in this article aimed to create a model to facilitate a credible prediction of the effect on influenza vaccination contingent upon valid medical data. A neural network approach was utilized, and its presentation was compared with using the logistic regression model
The three neural network algorithms that were tested include multilayer perceptron, radial basis, and probabilistic in conjunction with parameter optimization and regularization techniques to create an influenza vaccination model that could be used for prediction purposes in the medical practice of primary health care physicians, where the vaccine is usually dispensed (Tricia- Majnaric, Zekic-Susac, Sarlija, & Vitale, 2010). The variety of input variables was determined from the model of the vaccine strain, which has been altered and which a poor influenza reaction is likely. The action of models was quantified by the standard hit rate of difference in vaccine outcomes. Sensitivity analysis was performed on the best model, and the importance of input variables was discussed (Tricia- Majnaric, Zekic-Susac, Sarlija, & Vitale, 2010).
Logistic regression was widely used for dissecting the multivariate data, including dichotomous reactions with this research study. Logistic regression is identified as an analysis relationship between multiple independent variables and a single dependent variable which yields a predictive equation (Polit, 2010). The three neural network algorithms along with the logistic regression model were implemented to deliver the influenza vaccination probability model and apply it for prediction purposes within practice outcomes. Another statistical method that could address the research problem discussed in this article is the analysis of variance (ANOVA) statistical technique. ANOVA entails analyzing and arranging differences among three or more groups being compared to draw inferences. From this research study, the three NN algorithms, multilayer perceptron (MLP), radial-basis function network (RBFN), and probabilistic network (PNN), were tested and analyzed to draw an inferential conclusion.
Propose potential remedies to address the weaknesses of each study.
A strength of this study was the degree of the sensitivity and specificity analysis that was appropriately expressed. The generalization ability of the models used by a 10-fold cross-validation procedure showed that the model attained by multilayer perception produced the highest average hit rate among neural network algorithms and also outperformed the logistic regression model about sensitivity and specificity discussed (Tricia- Majnaric, Zekic-Susac, Sarlija, & Vitale, 2010). The sensitivity analysis was also implemented on the best models, and the vitality of the input variables was evaluated. A weakness of this study was the small sample size. The study consisted of 90 patients out of 150 people who required the influenza vaccine between 2003-2004 in Croatia. A more significant sample number would have been beneficial in this dataset and incorporating other methods to discover a more successful model.
Analyze the importance of this study to evidence-based practice, the nursing profession, or society.
The importance of prevention and control of the influence epidemic is imperative to the nursing profession and health care society. Based on the results of this research study, it is indicated that both types of data, those related to previous influenza viruses exposure and those describing the health status of examinees, influence outcome values of performed predictive models and could be used as efficient predictors of the influenza vaccine efficacy discussed (Tricia- Majnaric, Zekic-Susac, Sarlija, & Vitale, 2010). This is important, especially in the elderly, as this population has been more affected by the influenza virus. The available vaccines are less
effective in this age group. With new vaccine preparations and approaches, the effectiveness of influenza vaccines can be implemented through evidence-based practice.
