DESCRIPTION (provided by applicant): Today's advanced imaging modalities are acquiring more and more images that must be interpreted in less time. Concerns have been raised that radiologist workloads are so demanding that fatigue and reduced time for interpretation are negatively impacting diagnostic accuracy. Inadequate knowledge about the frequency, cause and impact of errors, as well as effective methods for error prevention is a major obstacle for improving health care quality. The failure to report abnormal radiographic findings accounts for about half the errors made. Avoiding false- negative errors is critical - with such errors treatmen does not occur. In the previous funding period we demonstrated that fatigue significantly reduces detection accuracy in simple detection tasks and that oculomotor strain is a contributing factor. The goal of the proposed research is to determine whether cognitive fatigue can more accurately and fully account for increases in errors in complex radiologic decision tasks. The long-term goal is to reduce diagnostic errors by studying an obvious but serious problem, fatigue, to determine whether it is indeed a root cause of error. This research will address the problem by applying comprehensive measures of cognitive fatigue and determining whether they generate diagnostic errors. At the end of the project, we will understand the influence of cognitive fatigue on diagnostic accuracy, which will help us in our general goal of reducing diagnostic errors thereby improving patient care. Our overall hypothesis is that the current practice of radiology produces cognitive fatigue that reduces diagnostic accuracy. Progress in understanding the causes of error in diagnostic radiology has been achieved by experiments focusing on error-prone situations such as Satisfaction of Search (SOS), but to date the role of fatigue in SOS has yet to be examined and thus the first aim will discover ways to help radiologists obviate SOS errors by testing whether cognitive fatigue exacerbates the SOS phenomenon. Our second and third aims relate cognitive fatigue to radiological performance using two types of complex imaging tasks studied before and after long hours of image interpretation work. The accuracy and efficiency of radiologist's reports will be analyzed and correlated with measures of cognitive fatigue.

描述（由申请人提供）：当今的高级成像方式正在获取越来越多的图像，这些图像必须在更少的时间内进行解释。人们一直担心放射科医生的工作量是如此要求，以至于疲劳和减少解释的时间对诊断准确性产生了负面影响。关于错误的频率，原因和影响的知识不足以及预防错误的有效方法是改善医疗保健质量的主要障碍。未报告异常的射线照相发现约为犯错误的一半。避免错误 - 负错误至关重要 - 如果没有发生这种错误。在上一个资金期间，我们证明疲劳可显着降低简单检测任务中的检测准确性，而眼动菌株是一个因素。拟议的研究的目的是确定认知疲劳是否可以更准确，并充分说明复杂的放射学决策任务中错误的增加。长期目标是通过研究一个明显但严重的问题（疲劳）来减少诊断错误，以确定它是否确实是错误的根本原因。这项研究将通过采用全面的认知疲劳措施来解决该问题，并确定它们是否会产生诊断错误。在项目结束时，我们将了解认知疲劳对诊断准确性的影响，这将帮助我们实现减少诊断错误的一般目标，从而改善患者护理。我们的总体假设是，当前的放射学实践会产生认知疲劳，从而降低了诊断准确性。 Progress in understanding the causes of error in diagnostic radiology has been achieved by experiments focusing on error-prone situations such as Satisfaction of Search (SOS), but to date the role of fatigue in SOS has yet to be examined and thus the first aim will discover ways to help radiologists obviate SOS errors by testing whether cognitive fatigue exacerbates the SOS phenomenon.我们的第二和第三目的将认知疲劳与放射学性能相关联，使用了长时间的图像解释工作之前和之后研究的两种类型的复杂成像任务。放射科医生报告的准确性和效率将与认知疲劳的度量进行分析并相关。
