This paper is a report of a study of perceived levels of mental, physical and total fatigue, and also acute and chronic fatigue states, among registered nurses. Relationships between dimensions of fatigue and performance were investigated, as were differences in fatigue across levels of several demographic and work environment variables.
Fatigue is a factor that has been linked to performance decrements in healthcare workers. As a result of the nature of their work, nurses may be particularly susceptible to multiple dimensions of fatigue, and their performance is closely linked to patient safety.
An online survey was used to measure mental, physical, and total fatigue dimensions, acute and chronic fatigue states, and performance. Participants were recruited via convenience sampling in cooperation with professional nursing organizations; 745 registered nurses completed the survey between February 2008 and April 2009.
Reported mental fatigue levels were higher than physical fatigue levels, and acute fatigue levels were higher than chronic fatigue levels. All fatigue dimensions and states were negatively correlated with perceived performance. Longer shift lengths and hours worked per week were associated with increases in physical and total fatigue levels. Mental, physical and total fatigue levels also differed with shift schedule.
Fatigue levels were negatively correlated with performance, further supporting the role of fatigue in nurse performance. Work environment variables were strongly associated with differences in perceived levels of fatigue. By altering the work environment, it may thus be possible to reduce fatigue levels and the rates of medical errors.
本文报告了一项针对注册护士感知的精神、身体和总体疲劳程度，以及急性和慢性疲劳状态的研究。研究调查了疲劳维度与绩效之间的关系，以及在几个人口统计学和工作环境变量水平上的疲劳差异。
疲劳是与医疗保健工作者绩效下降相关的一个因素。由于工作性质的原因，护士可能特别容易受到多种疲劳维度的影响，他们的绩效与患者安全密切相关。
采用在线调查的方式测量精神、身体和总体疲劳维度、急性和慢性疲劳状态以及绩效。参与者是通过与专业护理组织合作的便利抽样方法招募的；2008 年 2 月至 2009 年 4 月期间，共有 745 名注册护士完成了调查。
报告的精神疲劳水平高于身体疲劳水平，急性疲劳水平高于慢性疲劳水平。所有疲劳维度和状态均与感知绩效呈负相关。较长的轮班时间和每周工作时间与身体和总体疲劳水平的增加有关。精神、身体和总体疲劳水平也因轮班时间表而异。
疲劳水平与绩效呈负相关，进一步支持了疲劳对护士绩效的影响。工作环境变量与感知疲劳水平的差异密切相关。通过改变工作环境，可能降低疲劳水平和医疗失误率。
