Occupational fatigue is an important challenge in improving health and safety in health care systems. A secondary analysis of cross-sectional data from a survey sample comprised 340 hospital nurses was conducted to explore the relationships between components of the nursing work system (person, tasks, tools and technology, environment, organisation) and nurse fatigue and recovery levels. All components of the work system were significantly associated with changes in fatigue and recovery. Results of a tree-based classification method indicated significant interactions between multiple work system components and fatigue and recovery. For example, the relationship between a task variable of 'excessive work' and acute fatigue varied based on an organisation variable related to 'time to communicate with managers/supervisors'. A work systems analysis contributes to increased understanding of fatigue, allowing for a more accurate representation of the complexity in health care systems to guide future research and practice to achieve increased nurse health and safety. Practitioner Summary: This paper explored the relationships between nursing work system components and nurse fatigue. Findings revealed significant interactions between work system components and nurses' fatigue and recovery. A systems approach allows for a more accurate representation of complexity in work systems and can guide interventions to improve nurse health and safety.
职业疲劳是改善医疗保健系统健康与安全方面的一项重要挑战。对来自一项调查样本的340名医院护士的横断面数据进行了二次分析，以探究护理工作系统的各个组成部分（人员、任务、工具与技术、环境、组织）与护士疲劳及恢复水平之间的关系。工作系统的所有组成部分均与疲劳和恢复的变化显著相关。基于树的分类方法的结果表明，多个工作系统组成部分与疲劳和恢复之间存在显著的相互作用。例如，“工作量过大”这一任务变量与急性疲劳之间的关系会因与“与经理/主管沟通的时间”相关的组织变量而有所不同。工作系统分析有助于增进对疲劳的理解，从而更准确地呈现医疗保健系统的复杂性，以指导未来的研究和实践，实现提高护士的健康与安全水平。从业者总结：本文探究了护理工作系统组成部分与护士疲劳之间的关系。研究结果显示工作系统组成部分与护士的疲劳和恢复之间存在显著的相互作用。系统方法能够更准确地呈现工作系统的复杂性，并可指导干预措施以改善护士的健康与安全。
