Abstract

Background

Emergency departments (ED) nurses experience high mental workloads because of unpredictable work environments; however, research evaluating ED nursing workload using a tool incorporating nurses’ perception is lacking. Quantify ED nursing subjective workload and explore the impact of work experience on perceived workload.

Methods

Thirty-two ED nurses at a tertiary academic hospital in the Republic of Korea were surveyed to assess their subjective workload for ED procedures using the National Aeronautics and Space Administration Task Load Index (NASA-TLX). Nonparametric statistical analysis was performed to describe the data, and linear regression analysis was conducted to estimate the impact of work experience on perceived workload.

Results

Cardiopulmonary resuscitation (CPR) had the highest median workload, followed by interruption from a patient and their family members. Although inexperienced nurses perceived the ‘special care’ procedures (CPR and defibrillation) as more challenging compared with other categories, analysis revealed that nurses with more than 107 months of experience reported a significantly higher workload than those with less than 36 months of experience.

Conclusion

Addressing interruptions and customizing training can alleviate ED nursing workload. Quantified perceived workload is useful for identifying acceptable thresholds to maintain optimal workload, which ultimately contributes to predicting nursing staffing needs and ED crowding.

使用 NASA-TLX 在任务层面量化急诊科护理工作量：探索性描述研究

背景急诊科（ED）护士由于工作环境的不可预测性而承受着高强度的脑力劳动；然而，目前还缺乏使用包含护士感知的工具来评估急诊科护理工作量的研究。方法采用美国国家航空航天局任务负荷指数（NASA-TLX）对大韩民国一家三级学术医院的 32 名急诊科护士进行了调查，以评估他们在急诊科程序中的主观工作量。结果心肺复苏术（CPR）的工作量中位数最高，其次是患者及其家属的中断。尽管缺乏经验的护士认为 "特殊护理 "程序（心肺复苏术和除颤术）与其他类别相比更具挑战性，但分析表明，工作经验超过 107 个月的护士报告的工作量明显高于工作经验少于 36 个月的护士。量化的感知工作量有助于确定可接受的阈值，以维持最佳工作量，最终有助于预测护理人员需求和急诊室拥挤情况。
