A Systematic Approach Utilizing the System Engineering Initiative for Patient Safety 2.0 Model to Mitigate Fatigue in ER

Abstract

The focus of the study addresses fatigue among healthcare workers in the Emergency Room (ER), which is vital in delivering health services but is prone to worker fatigue. It evaluates physical and mental fatigue using objective measures like cardiovascular load (%CVL) and the Bourdon Wiersma test. Leveraging the System Engineering Initiative for Patient Safety 2.0 (SEIPS 2.0) model, it comprehensively analyzes fatigue factors. Data collection includes surveys and statistical analysis through Structural Equation Modeling-Partial Least Squares (SEM-PLS). Results show all workers experience fatigue, with physical fatigue affected by age and gender and mental fatigue influenced by workload. The outer model analysis confirms convergent and discriminant validity, as well as the reliability of the constructs. The inner model analysis reveals the work system significantly affects fatigue while the process does not. The study emphasizes the importance of addressing fatigue to improve worker well-being and enhance patient care in the ER, providing actionable insights for healthcare organizations.
