项目摘要

DESCRIPTION (provided by applicant): The objective of this project is to develop and test display technology that will aid anesthesiologists in diagnosing and treating unexpected events. Unexpected events occur during 30% of all anesthesia cases. Thirty percent of these events have a significant impact on the patient's perioperative course. Anesthesiologists discover critical events earlier and diagnose the events more accurately when data is presented in a graphic display. Preliminary studies found that when a graphic display of anesthesia breathing circuit faults was used, it reduced event correction time from 45 to 17 seconds. Anesthesiologists who used a cardiovascular graphic display detected myocardial ischemia 1.1 minutes after its onset compared to 3.1 minutes when the display was not used. Errors made in diagnosing shock states decreased by 66% when a graphic display was used. Our research plan is to develop and implement an integrated graphic display of pulmonary and cardiovascular variables. Data-driven visual metaphors will be refined through an iterative design process. Usability testing will guide design enhancements. The resulting display will be implemented in real time to receive and display data from a full-scale patient simulator. The utility of the graphic display will be measured using a realistic patient simulator. Twenty anesthesiologists will be called into a simulated operating room to assist a new resident in managing six unique surgical procedures. Five of the six procedures will have a critical event in progress at the time the clinician enters the room. We will record the time to make the correct diagnosis by analyzing video recordings and data records. Treatment of the event will be scored in comparison to the "gold standard" treatment protocol. We expect to find that the pulmonary and cardiovascular display will be a cognitive aid to the anesthesiologist in diagnosing unusual events more rapidly and more accurately. Phase I results will be analyzed by clinical consultants and the resulting prototype display will move to the Phase II program.

描述（由申请人提供）：该项目的目的是开发和测试显示技术，以帮助麻醉师诊断和治疗意外事件。在所有麻醉病例中，发生意外事件。这些事件中有30％对患者的围手术期有重大影响。麻醉师早些时候发现关键事件，并在图形显示中显示数据时更准确地诊断事件。初步研究发现，当使用麻醉呼吸电路故障的图形显示时，它将事件校正时间从45秒降低到17秒。麻醉师使用心血管图形显示器，在发作后1.1分钟检测到心肌缺血，而没有使用显示器时3.1分钟。使用图形显示时，诊断冲击状态的错误降低了66％。我们的研究计划是开发和实施肺和心血管变量的集成图形显示。数据驱动的视觉隐喻将通过迭代设计过程进行完善。可用性测试将指导设计增强功能。所得的显示将实时实现，以接收和显示全尺度患者模拟器的数据。图形显示的实用程序将使用现实的患者模拟器进行测量。二十个麻醉师将被召集到模拟手术室中，以帮助新居民管理六个独特的手术程序。在临床医生进入房间时，六个程序中有五个将在进行关键事件。我们将通过分析视频记录和数据记录来记录正确诊断的时间。与“黄金标准”治疗方案相比，该事件的治疗将得到评分。我们希望发现，肺和心血管表现将是对麻醉师的认知辅助，以更快，更准确地诊断异常事件。第一阶段的结果将由临床顾问分析，由此产生的原型显示将转移到II期计划。
