COMMERCIALZATION OF METAPHOR GRAPHIC PHYSIOLOGIC DISPLAY

描述（由申请人提供）： 本项目的目标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。30%的麻醉病例发生意外事件。这些事件中有30%对患者的围手术期过程有显著影响。 当数据以图形显示时，麻醉师可以更早地发现关键事件并更准确地诊断事件。初步研究发现，当使用麻醉呼吸回路故障的图形显示时，它将事件纠正时间从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后1.1分钟检测到心肌缺血，而不使用显示器时为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一个综合的图形显示肺和心血管变量。数据驱动的视觉隐喻将通过迭代设计过程进行优化。可用性测试将指导设计增强。所得到的显示将以真实的时间实现，以接收和显示来自全尺寸患者模拟器的数据。 将使用真实的患者模拟器测量图形显示的效用。二十名麻醉师将被召集到模拟手术室，协助新住院医师管理六项独特的外科手术。在临床医生进入手术室时，六个手术中的五个将有正在进行的关键事件。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。与"金标准"治疗方案相比，对事件的治疗进行评分。我们期望发现，肺和心血管显示将是一个认知辅助麻醉师在诊断不寻常的事件更迅速，更准确。第一阶段的结果将由临床顾问进行分析，由此产生的原型显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.
