COMMERCIALZATION OF METAPHOR GRAPHIC PHYSIOLOGIC DISPLAY

描述(由申请人提供)： 该项目的目标是开发和测试显示技术，以帮助麻醉医生诊断和治疗意外事件。意外事件发生在30%的麻醉病例中。其中30%的事件对患者的围手术期进程有重大影响。 麻醉师更早地发现关键事件，并在数据以图形显示时更准确地诊断事件。初步研究发现，当使用麻醉呼吸回路故障的图形显示时，事件纠正时间从45秒减少到17秒。使用心血管图形显示器的麻醉师在心肌缺血发作1.1分钟后检测到心肌缺血，而不使用显示器的情况下，这一时间为3.1分钟。当使用图形显示时，诊断休克状态的错误减少了66%。 我们的研究计划是开发和实现肺和心血管变量的综合图形显示。数据驱动的视觉隐喻将通过迭代设计过程得到提炼。可用性测试将指导设计增强。最终的显示将实时实现，以接收和显示来自全尺寸患者模拟器的数据。 图形显示的效用将使用逼真的患者模拟器进行测量。20名麻醉师将被召集到一个模拟的手术室，帮助一名新住院医生管理六种独特的手术程序。当临床医生进入房间时，六个程序中的五个将有一个危急事件正在进行中。我们将通过分析视频记录和数据记录来记录做出正确诊断的时间。该赛事的治疗方案将与“黄金标准”治疗方案进行比较。我们期望发现，肺和心血管的显示将有助于麻醉师更快、更准确地诊断异常事件。第一阶段的结果将由临床顾问进行分析，由此产生的原型展示将转移到第二阶段计划。

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.
