Abstract
Background: Workplace violence, defined as any disruptive behavior or threat to employees, seriously threatens junior nurses. Compared with senior nurses, junior nurses are more vulnerable to workplace violence due to inexperience, low professional recognition, and limited mental resilience. However, there is an absence of research discussing the workplace violence risk of junior nurses, in particular, the lack of analysis of critical factors within the multiple influences and the lack of targeted risk prediction models.
Objective: Considering the multiple influencing factors faced by junior nurses, this study aims to predict the risk of workplace violence using interpretable machine learning models and identify the critical influencing factors and their nonlinear effects.
Design: An observational, cross-sectional study design.
Participants: A total of 5663 junior registered nurses in 90 tertiary hospitals in Sichuan Province, China.
Methods: Data are all obtained through a questionnaire survey. An interpretable machine learning framework, including the Light Gradient Boosting Machine (LightGBM) model and two post hoc interpretable methods, Accumulate Local Effect and SHapely Additive exPlanations (SHAP), are conjoined.
Results: The LightGBM model is more accurate than other machine learning methods, achieving an area under the receiver operating characteristic curve of 0.761 and a Brier score of 0.198 on the workplace violence prediction task. Among the dozens of potential influences input into the predictive model, seeing medical complaints, psychological demands, professional identity, etc., are the most critical predictors of workplace violence.
Conclusions: The proposed LightGBM-SHAP-ALE approach dynamically and effectively identifies junior nurses at high risk of workplace violence, providing a foundation for timely detection and intervention.
期刊介绍:
The Journal of Nursing Management is an international forum which informs and advances the discipline of nursing management and leadership. The Journal encourages scholarly debate and critical analysis resulting in a rich source of evidence which underpins and illuminates the practice of management, innovation and leadership in nursing and health care. It publishes current issues and developments in practice in the form of research papers, in-depth commentaries and analyses.
The complex and rapidly changing nature of global health care is constantly generating new challenges and questions. The Journal of Nursing Management welcomes papers from researchers, academics, practitioners, managers, and policy makers from a range of countries and backgrounds which examine these issues and contribute to the body of knowledge in international nursing management and leadership worldwide.
The Journal of Nursing Management aims to:
-Inform practitioners and researchers in nursing management and leadership
-Explore and debate current issues in nursing management and leadership
-Assess the evidence for current practice
-Develop best practice in nursing management and leadership
-Examine the impact of policy developments
-Address issues in governance, quality and safety
