Chi, C., Wu, H., Huan, C., & Lee, Y. (2017). Using linear regression to identify critical demographic variables affecting patient safety culture from viewpoints of physicians and nurses. Hospital Practices and Research, 2(2), 47–53. doi:10.15171/hpr.2017.12
Description: The article by Chi et al. (2017) investigates the impact of demographic variables on the perceptions of patient safety culture among physicians and nurses in a hospital setting. The researchers employ linear regression analysis to pinpoint which demographic factors significantly influence these perceptions, aiming to enhance patient safety by understanding these relationships.
Goals and Purposes of the Research Study
The primary goals of the research study are:
To identify which demographic variables (e.g., age, gender, years of experience) significantly affect the perceptions of patient safety culture among healthcare professionals.
To provide insights that can help hospital administrators and policymakers improve patient safety practices by addressing the specific needs of different demographic groups.
Use of Linear Regression in the Study
Methodology: Linear regression analysis is utilized to examine the relationship between demographic variables and the perceptions of patient safety culture. The independent variables in the regression models include age, gender, education level, and years of experience, while the dependent variable is the score reflecting the perception of patient safety culture.
Results: The regression analysis revealed that certain demographic variables, such as years of experience and age, had a statistically significant impact on the perception of patient safety culture. For example, more experienced healthcare professionals generally had more positive perceptions of patient safety.
Other Quantitative and Statistical Methods
Other quantitative and statistical methods that could be used to address the research issue include:
Logistic Regression: To handle binary outcomes or categorical data, logistic regression could be applied to analyze the probability of positive or negative perceptions of patient safety culture.
Multivariate Analysis of Variance (MANOVA): This method could be used to assess the impact of multiple demographic variables simultaneously on the perceptions of patient safety culture.
Structural Equation Modeling (SEM): SEM could provide a more comprehensive understanding of the relationships between multiple independent and dependent variables, allowing for the analysis of direct and indirect effects.
Strengths and Weaknesses of the Study
Strengths:
Focus on Demographic Variables: The study provides valuable insights into how demographic factors influence perceptions of patient safety, which can inform targeted interventions.
Quantitative Approach: The use of linear regression allows for a clear identification of statistically significant relationships.
Weaknesses:
Limited Scope: The study focuses only on a limited set of demographic variables and does not consider other potential factors, such as organizational culture or job satisfaction.
Cross-Sectional Design: The cross-sectional nature of the study limits the ability to draw causal inferences.
Potential Remedies for Identified Weaknesses
Expand Variable Set: Future studies could include a broader range of variables, such as organizational factors, to provide a more comprehensive analysis.
Longitudinal Design: Implementing a longitudinal design would allow researchers to observe changes over time and make stronger causal inferences.
Importance of the Study
This study is important to evidence-based practice, the nursing profession, and society for several reasons:
Evidence-Based Interventions: By identifying key demographic factors that affect perceptions of patient safety, the study provides a foundation for developing evidence-based interventions tailored to specific groups of healthcare professionals.
Improving Patient Safety: Understanding the demographic influences on patient safety culture can help hospital administrators design targeted strategies to enhance overall patient safety, ultimately leading to better patient outcomes.
Professional Development: For the nursing profession, the findings highlight the need for tailored professional development programs that address the unique needs of different demographic groups, promoting a safer healthcare environment.
Examples:
Hospitals could implement mentorship programs for less experienced nurses to improve their perceptions and practices related to patient safety.
Policymakers could design age-specific training modules to address the varying needs and perspectives of younger versus older healthcare professionals.
By addressing these demographic factors, healthcare institutions can foster a more positive patient safety culture, ultimately benefiting both healthcare professionals and patients.

Use of Regression Analysis in Clinical Practice
Regression analysis provides researchers with a powerful tool to predict and explore future outcomes, essential for improving patient care and achieving sustained positive outcomes. Linear regression is used to “estimate the value of a dependent variable based on the value of an independent variable” (Gray & Grove, 2020, p. 675). This discussion will critically analyze an article that employs linear regression in its methodology, highlighting its strengths, weaknesses, and implications for nursing practice.
The article selected for this analysis is “Predictors of Transformational Leadership of Nurse Managers” by Echevarria, Patterson, and Krouse (2017). The study aims to identify predictors of transformational leadership among nurse managers, focusing on how demographic and professional factors contribute to developing these leadership qualities. Understanding these predictors is crucial for developing interventions and training programs to enhance leadership in the nursing profession.
The study utilizes linear regression to examine the relationship between various independent variables, such as age, education level, and years of experience, and the dependent variable is the transformational leadership score of nurse managers. The results indicate that higher educational attainment and more years of experience are significant predictors of transformational leadership (Echevarria, Patterson, & Krouse, 2017). This finding suggests that investing in education and professional development could enhance leadership qualities in nursing managers.
Despite the strengths of this study, such as addressing an essential aspect of nursing leadership and the appropriate use of linear regression for identifying relationships between variables, there are notable weaknesses. The reliance on self-reported data can introduce bias, and the cross-sectional design limits the ability to infer causality. Additionally, the study may not account for all potential confounding variables that could influence transformational leadership (Echevarria, Patterson, & Krouse, 2017).
To address these weaknesses, future research could incorporate objective measures of leadership performance, such as peer evaluations or patient outcomes, to supplement self-reported data. Conducting longitudinal studies would allow researchers to observe changes over time and make more robust causal inferences about transformational leadership development. More comprehensive statistical models, such as structural equation modeling (SEM), can help account for confounding variables and provide a clearer picture of the relationships between predictors and outcomes.
This study is significant for evidence-based practice as it highlights key factors that contribute to transformational leadership among nurse managers. Understanding these predictors can guide the development of educational and professional development programs tailored to enhance leadership skills. For the nursing profession, promoting transformational leadership can lead to improved team dynamics, job satisfaction, and patient care outcomes. Additionally, the study contributes to the broader societal goal of ensuring high-quality healthcare by fostering effective leadership within nursing teams. By addressing the identified weaknesses and leveraging the findings, nursing educators and policymakers can implement strategies to cultivate transformational leadership, benefiting the entire healthcare system.
