PURPOSE
To relate subjective workload (WL) levels to errors for routine clinical tasks.
METHODS AND MATERIALS
Nine physicians (4 faculty and 5 residents) each performed 3 radiation therapy planning cases. The WL levels were subjectively assessed using National Aeronautics and Space Administration Task Load Index (NASA-TLX). Individual performance was assessed objectively based on the severity grade of errors. The relationship between the WL and performance was assessed via ordinal logistic regression.
RESULTS
There was an increased rate of severity grade of errors with increasing WL (P value = .02). As the majority of the higher NASA-TLX scores, and the majority of the performance errors were in the residents, our findings are likely most pertinent to radiation oncology centers with training programs.
CONCLUSIONS
WL levels may be an important factor contributing to errors during radiation therapy planning tasks.
目的
将主观工作量（WL）水平与常规临床任务中的错误相关联。
方法与材料
九名医生（4名教员和5名住院医师）每人完成3例放射治疗计划病例。使用美国国家航空航天局任务负荷指数（NASA - TLX）对WL水平进行主观评估。根据错误的严重程度等级客观评估个人表现。通过有序逻辑回归评估WL与表现之间的关系。
结果
随着WL增加，错误严重程度等级的发生率增加（P值 = 0.02）。由于大多数较高的NASA - TLX分数以及大多数表现错误都出现在住院医师中，我们的发现可能与有培训项目的放射肿瘤学中心最为相关。
结论
WL水平可能是放射治疗计划任务中导致错误的一个重要因素。
