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）：当今先进的成像方式正在获取越来越多的图像，必须在更短的时间内解释这些图像。人们担心放射科医生的工作量如此之大，以至于疲劳和解释时间的减少会对诊断准确性产生负面影响。对错误的频率、原因和影响以及错误预防的有效方法认识不足是提高医疗保健质量的主要障碍。未报告异常放射线检查结果约占所犯错误的一半。避免假阴性错误至关重要——出现此类错误时就不会进行治疗。在之前的资助期间，我们证明疲劳会显着降低简单检测任务中的检测准确性，而动眼神经紧张是一个影响因素。拟议研究的目标是确定认知疲劳是否可以更准确、更全面地解释复杂放射决策任务中错误的增加。长期目标是通过研究疲劳这个明显但严重的问题来确定它是否确实是错误的根本原因，从而减少诊断错误。这项研究将通过应用认知疲劳的综合测量方法并确定它们是否产生诊断错误来解决这个问题。在项目结束时，我们将了解认知疲劳对诊断准确性的影响，这将有助于我们实现减少诊断错误从而改善患者护理的总体目标。我们的总体假设是，当前的放射学实践会产生认知疲劳，从而降低诊断准确性。通过针对容易出错的情况（例如搜索满意度（SOS））的实验，在了解诊断放射学错误的原因方面取得了进展，但迄今为止，疲劳在 SOS 中的作用尚未得到检验，因此第一个目标是通过测试认知疲劳是否会加剧 SOS 现象，找到帮助放射科医生避免 SOS 错误的方法。我们的第二个和第三个目标使用在长时间图像判读工作之前和之后研究的两种类型的复杂成像任务，将认知疲劳与放射性能联系起来。将分析放射科医生报告的准确性和效率，并将其与认知疲劳的测量相关联。
