Assignment 2 4005

Create a 2-4 page report on an interview you have conducted with a health care professional colleague. You will identify an issue from the interview that could be improved with an interdisciplinary approach, and review best practices and evidence to address the issue. This is the first of three assessments that build on each other.

### **Introduction**

As a baccalaureate-prepared nurse, your participation and leadership in intra- and interdisciplinary teams will be vital to the health outcomes for your patients and organization. One way to approach designing an improvement project, and implementing change, is to become knowledgeable about the challenges that the organization is facing. To do this, you will interview a healthcare professional. This can be a peer, a nursing colleague, administrator, or someone who could provide you with sufficient knowledge and information on a particular problem or concern within the organization.

It would be an excellent choice to complete the Plan-Do-Study-Act (PDSA) Cycle activity prior to developing the report. The activity consists of four questions that create the opportunity to check your understanding of best practices related to each stage of the PDSA cycle, which is one of a number of change models you can read about. The information gained from completing this activity will promote your success with the Interview and Interdisciplinary Issue Identification report. This will take just a few minutes of your time and is not graded.

### **Professional Context**

By interviewing a healthcare colleague of your choice, you will begin to gather information about an interprofessional collaboration problem that your colleague is experiencing, or has experienced, in the workplace. You will identify a change theory and leadership strategies that can be applied to address this problem.

### **Overview**

This assessment is the first of three related assessments in which you will gather interview information, design a proposal for interdisciplinary problem-solving, and report on how an interdisciplinary improvement plan could be implemented in a place of practice. At the end of the course, your interviewee will have a proposal plan that they could present to stakeholders to address an interdisciplinary problem in the workplace.

You may interview a healthcare professional such as a fellow learner, nursing colleague, administrator, business partner, or another appropriate person who could provide you with sufficient information regarding an organizational problem or an area in which the organization is seeking improvements. Consult the
[Interview Guide [DOCX]](https://courseroom.capella.edu/courses/43445/files/7662863/download) for an outline of how to prepare and the types of information you will need to complete this project successfully.

### **Instructions**

For this assessment, you will report on the information gathered during your interview. You will discuss the interview strategy that you used to collect information. Your interview strategy should be supported by citations from the literature. The goal of this assessment is to analyze the interview data and identify an issue that would benefit from an interdisciplinary solution. This could be an issue that has not been addressed by an interdisciplinary approach or one that could benefit from improvements related to the interdisciplinary approach currently in use. Additionally, you will prepare for your Interdisciplinary Plan Proposal assessment by researching change theories, leadership strategies, and collaboration approaches that could be relevant to issue you have identified. Please be certain to review the scoring guide to confirm specific required elements of this assessment. Note that there are differences between basic, proficient and distinguished criteria.

Use the
[Interview and Issue Identification Template [DOCX]](https://courseroom.capella.edu/courses/43445/files/7662865/download) to help you stay organized and concise. As you complete the template, make sure you use APA format for in-text citations for the evidence and best practices that are informing your plan, as well as for the reference list at the end. (Because you're using a template, a title page is optional.)

Additionally, be sure to address the following criteria. Please study the scoring guide carefully so you know what is needed for a distinguished score.

· Summarize an interview focused on past or current issues at a healthcare organization.

· Identify an issue from an interview for which an evidence-based interdisciplinary approach would be appropriate.

· Describe change theories and a leadership strategy that could help in developing an interdisciplinary solution to an organizational issue.

· Describe collaboration approaches from the literature that could be relevant in establishing or improving an interdisciplinary team to address an organizational issue.

· Organize content so ideas flow logically with smooth transitions; contains few errors in grammar/punctuation, word choice, and spelling.

· Apply APA formatting to in-text citations and references exhibiting nearly flawless adherence to APA format.

### **Additional Requirements**

·
**Length of submission:** Use the provided template. Most submissions will be 2 to 4 pages in length. Be sure to include a reference page at the end of the plan.

·
**Number of references:** Cite a minimum of three sources of scholarly or professional evidence to support your central ideas. Resources should be no more than 5 years old. See the
[Capella University Library](https://lat.strategiced.com/redirect?linkid=1651).

·
**APA formatting:** Make sure that in-text citations and reference list follow current APA style. See the
[APA Module](https://lat.strategiced.com/redirect?linkid=2586).

### **Competencies Measured**

By successfully completing this assessment, you will demonstrate your proficiency in the following course competencies and scoring guide criteria:

· Competency 2: Explain how interdisciplinary collaboration can be used to achieve desired patient and systems outcomes.

· Summarize an interview focused on past or current issues at a health care organization.

· Describe collaboration approaches from the literature that could be relevant in establishing or improving an interdisciplinary team to address an organizational issue.

· Competency 3: Describe ways to incorporate evidence-based practice within an interdisciplinary team.

· Identify an issue from an interview for which an evidence-based interdisciplinary approach would be appropriate.

· Competency 4: Explain how change management theories and leadership strategies can enable interdisciplinary teams to achieve specific organizational goals.

· Describe change theories and a leadership strategy to develop an interdisciplinary solution to an organizational issue.

· Competency 5: Apply professional, scholarly, evidence-based communication strategies to impact patient, interdisciplinary team, and systems outcomes.

· Organize content so ideas flow logically with smooth transitions; contains few errors in grammar/punctuation, word choice, and spelling.

· Apply APA formatting to in-text citations and references, exhibiting nearly flawless adherence to APA format.

Systematic Reviews and Meta-Analyses

![A person in white protective suit and goggles looking at a computer AI-generated content may be incorrect.](https://www.sweetstudy.com/questions/wk-8-resp-epid)

Systematic reviews are an umbrella term for a number of different review designs, all with specific goals (e.g., identify scope of available research or gaps, reduce bias, statistically combine and analyze results from multiple studies). They differ from basic literature review articles that qualitatively summarize the literature on a topic and do not necessarily have inclusion or exclusion criteria.

Epidemiological meta-analyses are quantitative types of systematic reviews, in which summary measures of exposure–outcome associations are calculated based on the results of a selection of existing studies. In other words, a meta-analysis statistically combines the results from multiple studies, with the goal of calculating more precise measures, increasing sample size, or reducing bias in the combined results. The goal of meta-analysis is to obtain a more robust understanding of the relationship between an exposure and a health outcome than could be obtained from a single study. While meta-analyses are considered to be strong research designs because of their formal, statistical characteristics, they are not without weakness or critics. For instance, existing studies included in a meta-analysis may have strengths and limitations of their own.

For this Discussion, you examine the validity and strengths and limitations of systematic reviews and meta-analyses in epidemiological research.

**Systematic Reviews and Meta-Analyses in Epidemiological Research**

Systematic reviews and meta-analyses are potent tools in epidemiological research, providing high-quality evidence to guide healthcare decision-making. A systematic review aims to comprehensively identify, evaluate, and synthesize all available evidence on a specific research question using a structured methodology. A meta-analysis is a subtype of systematic review that applies statistical techniques to quantitatively combine results from multiple studies to provide more precise estimates of effects (Seidler et al., 2020). Both methods are crucial for informing clinical practice, policymaking, and identifying gaps in the literature. However, they are not without limitations.

The validity of systematic reviews lies in their methodological rigor. By following transparent processes and predefined inclusion and exclusion criteria, systematic reviews reduce bias and improve reproducibility. The PRISMA 2020 statement, updated by Page et al. (2021), outlines essential criteria to enhance the transparency and quality of systematic reviews, including guidance on reporting methods, data sources, and synthesis strategies. This updated standard strengthens the reliability of systematic reviews by ensuring consistency and completeness in reporting.

One significant strength of systematic reviews is their ability to summarize a large body of research in an objective manner. They help clinicians and policymakers quickly understand what is known about a topic without having to review each individual study. Another strength is their potential to identify gaps in knowledge and inform future research agendas. However, limitations include the risk of publication bias, where only studies with positive results are published and included, and heterogeneity among studies, which can make meaningful comparisons difficult.

Meta-analyses enhance the impact of systematic reviews by statistically combining results to improve power and precision. By pooling data, meta-analyses can detect small but clinically significant effects that individual studies may miss. For example, Driscoll et al. (2018) conducted a meta-analysis on nurse-to-patient ratios and found that lower ratios were significantly associated with better patient outcomes. This level of evidence supports workforce policy development and quality improvement initiatives.

Despite their strengths, meta-analyses have limitations. One major concern is the variability in study quality. If a meta-analysis includes poorly designed studies, its overall conclusions may be flawed. Additionally, publication bias and selective reporting can skew results. As Haidich (2010) noted, the statistical combination of biased studies does not eliminate the biases themselves. This limitation underlines the importance of critically appraising the quality of included studies using established tools before conducting meta-analysis.

Prospective meta-analyses, as discussed by Seidler et al. (2020), offer an innovative solution to some of these challenges by pre-planning the inclusion of studies and coordinating efforts across multiple research teams. This approach can improve consistency and reduce selection bias, strengthening the validity of findings.

In conclusion, systematic reviews and meta-analyses are indispensable for synthesizing evidence in epidemiological research. When conducted and reported properly, they offer high-level evidence to guide practice and policy. Nonetheless, researchers must be cautious of limitations such as publication bias, study quality variation, and heterogeneity. Following guidelines like PRISMA and exploring newer models such as prospective meta-analyses can help mitigate these concerns and enhance the utility of these methodologies in health research.

Systematic Reviews and Meta-Analyses

![A person in white protective suit and goggles looking at a computer AI-generated content may be incorrect.](https://www.sweetstudy.com/questions/wk-8-resp-epid)

Systematic reviews are an umbrella term for a number of different review designs, all with specific goals (e.g., identify scope of available research or gaps, reduce bias, statistically combine and analyze results from multiple studies). They differ from basic literature review articles that qualitatively summarize the literature on a topic and do not necessarily have inclusion or exclusion criteria.

Epidemiological meta-analyses are quantitative types of systematic reviews, in which summary measures of exposure–outcome associations are calculated based on the results of a selection of existing studies. In other words, a meta-analysis statistically combines the results from multiple studies, with the goal of calculating more precise measures, increasing sample size, or reducing bias in the combined results. The goal of meta-analysis is to obtain a more robust understanding of the relationship between an exposure and a health outcome than could be obtained from a single study. While meta-analyses are considered to be strong research designs because of their formal, statistical characteristics, they are not without weakness or critics. For instance, existing studies included in a meta-analysis may have strengths and limitations of their own.

For this Discussion, you examine the validity and strengths and limitations of systematic reviews and meta-analyses in epidemiological research.

**Systematic Reviews and Meta-Analyses in Epidemiological Research**

Systematic reviews and meta-analyses are potent tools in epidemiological research, providing high-quality evidence to guide healthcare decision-making.

Introduction

![A doctor working on a computer AI-generated content may be incorrect.](https://www.sweetstudy.com/questions/wk-8-resp-data)

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).

**A correlation matrix and multiple regression analysis are both statistical tools used to examine relationships between variables, but they serve different purposes and can complement each other in research.**

**A correlation matrix displays the strength and direction of linear relationships between pairs of variables using correlation coefficients (typically Pearson’s r). It provides a quick overview of which variables may be significantly related and therefore good candidates for inclusion in a regression model. For instance, if investigating patient falls, a correlation matrix might show significant relationships between variables such as nurse staffing levels, safety culture, and missed care—data points found to be influential in the study by Alanazi et al. (2023). A strong correlation between these predictors and fall rates would justify further exploration using multiple regression to understand their unique and combined effects on the outcome.**

**Multiple regression, on the other hand, quantifies how several independent variables predict or explain variance in a single continuous dependent variable. It provides beta coefficients, significance levels, and measures like R² to determine the relative contribution of each predictor. The correlation matrix can be used as a preliminary tool to detect multicollinearity—situations in which predictors are highly correlated with each other, potentially distorting the regression model’s reliability (Laureate Education, 2021).**

**Together, these tools offer a powerful approach: the correlation matrix for screening and diagnostic assessment, and multiple regression for hypothesis testing and predictive modeling. For example, Moradkhani et al. (2021) used chi-square tests and regression to analyze the impact of medication adherence on health-related quality of life. If they had continuous predictors, a correlation matrix might have helped select appropriate variables for a multiple regression model.**

**Regarding the second part of the question, the difference between logistic and multiple regression lies primarily in the type of outcome variable they analyze:**

·
**Multiple regression (also called linear regression) is used when the dependent variable is continuous (e.g., number of falls, quality of life scores). It assumes a linear relationship between independent and dependent variables (Creswell & Creswell, 2018).**

·
**Logistic regression is used when the dependent variable is binary or categorical (e.g., whether a patient was readmitted: yes/no). It models the probability of an event occurring, using odds ratios to interpret the influence of predictors (Polit & Beck, 2021).**

**Both regressions can accommodate multiple predictors, but the interpretation and application differ due to the outcome’s nature. Logistic regression is particularly useful in clinical settings where binary outcomes, such as medication adherence or the presence of complications, are common (Moradkhani et al., 2021).**

**In summary, a correlation matrix is a foundational step in identifying potential predictors for multiple regression. While multiple regression explains variance in continuous outcomes, logistic regression predicts categorical outcomes. Used together, these methods enable comprehensive analysis and evidence-based decision-making in nursing research and practice.**

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).

**A correlation matrix and multiple regression analysis are both statistical tools used to examine relationships between variables, but they serve different purposes and can complement each other in research.**

**A correlation matrix displays the strength and direction of linear relationships between pairs of variables using correlation coefficients (typically Pearson’s r). It provides a quick overview of which variables may be significantly related and therefore good candidates for inclusion in a regression model. For instance, if investigating patient falls, a correlation matrix might show significant relationships between variables such as nurse staffing levels, safety culture, and missed care—data points found to be influential in the study by Alanazi et al. (2023). A strong correlation between these predictors and fall rates would justify further exploration using multiple regression to understand their unique and combined effects on the outcome.**

**Multiple regression, on the other hand, quantifies how several independent variables predict or explain variance in a single continuous dependent variable. It provides beta coefficients, significance levels, and measures like R² to determine the relative contribution of each predictor. The correlation matrix can be used as a preliminary tool to detect multicollinearity—situations in which predictors are highly correlated with each other, potentially distorting the regression model’s reliability (Laureate Education, 2021).**

**Together, these tools offer a powerful approach: the correlation matrix for screening and diagnostic assessment, and multiple regression for hypothesis testing and predictive modeling. For example, Moradkhani et al. (2021) used chi-square tests and regression to analyze the impact of medication adherence on health-related quality of life. If they had continuous predictors, a correlation matrix might have helped select appropriate variables for a multiple regression model.**

**Regarding the second part of the question, the difference between logistic and multiple regression lies primarily in the type of outcome variable they analyze:**

·
**Multiple regression (also called linear regression) is used when the dependent variable is continuous (e.g., number of falls, quality of life scores). It assumes a linear relationship between independent and dependent variables (Creswell & Creswell, 2018).**

·
**Logistic regression is used when the dependent variable is binary or categorical (e.g., whether a patient was readmitted: yes/no). It models the probability of an event occurring, using odds ratios to interpret the influence of predictors (Polit & Beck, 2021).**

**Both regressions can accommodate multiple predictors, but the interpretation and application differ due to the outcome’s nature. Logistic regression is particularly useful in clinical settings where binary outcomes, such as medication adherence or the presence of complications, are common (Moradkhani et al., 2021).**

**In summary, a correlation matrix is a foundational step in identifying potential predictors for multiple regression. While multiple regression explains variance in continuous outcomes, logistic regression predicts categorical outcomes. Used together, these methods enable comprehensive analysis and evidence-based decision-making in nursing research and practice.**

The Advanced Pharmacology course is a crucial component of the education and training required for an advanced practitioner. Over the past eight weeks, this course has deepened my understanding of pharmacokinetics, pharmacodynamics, and the clinical application of various medications, all of which are essential for providing safe and effective patient care. This knowledge is particularly valuable as it enables advanced practitioners to make informed prescribing decisions, minimize adverse drug reactions, and improve patient outcomes.

One of the most significant aspects of this course has been learning how medications interact with the body and how patient-specific factors, such as age, genetics, and comorbidities, influence drug metabolism and efficacy. This is particularly important in managing chronic diseases such as hypertension, diabetes, and heart failure, where polypharmacy is common. By understanding drug interactions and contraindications, I will be able to optimize medication regimens and prevent complications such as drug-induced organ damage or adverse reactions.

Another key takeaway from this course is the importance of evidence-based practice in pharmacology. Staying updated with the latest clinical guidelines and research is essential for making informed prescribing decisions. This course has emphasized the need for continuous learning and the critical evaluation of research to ensure that the medications prescribed align with the most current standards of care. For instance, advancements in diabetes management, such as the use of SGLT2 inhibitors and GLP-1 receptor agonists, highlight the need for practitioners to be well-versed in newer pharmacological therapies to provide optimal patient care (American Diabetes Association, 2023).

Additionally, this course has reinforced the ethical and legal responsibilities associated with prescribing. As an advanced practitioner, I will be accountable for ensuring medication safety, preventing prescription errors, and educating patients about their medications. Understanding the principles of prescribing, including controlled substances regulations and patient adherence strategies, is critical for maintaining patient trust and ensuring compliance with legal and professional standards (Arcangelo et al., 2021).

Overall, the Advanced Pharmacology course has provided me with a strong foundation for my future role as an advanced practitioner. The knowledge gained will allow me to make well-informed clinical decisions, enhance patient safety, and contribute to improved health outcomes. By applying pharmacological principles and staying updated with emerging therapies, I will be better equipped to provide high-quality, evidence-based care to diverse patient populations.
