目的：目的是评估配置生命体征 (CVS) 显示器，该显示器旨在通过以图形方式呈现患者生命体征数据来支持快速检测和识别生理恶化。背景：重症监护病房 (ICU) 中的当前显示技术并未针对快速识别和识别患者的生理变化进行优化。为了更有效地支持护士，需要开发和评估图形或配置生命体征显示。方法：根据 ICU 护士在患者监护期间认知工作的研究结果开发了 CVS 显示。共有 42 名 ICU 护士解释了以传统数字格式 (n = 21) 或 CVS 显示屏上 (n = 21) 呈现的数据。在四种情况下评估临床数据解释（即识别患者状态）的响应时间和准确性。结果：在 CVS 显示条件下，数据解释速度和准确性显着提高；例如，在一种情况下，与数字显示条件相比，护士只需要一半的时间来解释数据，并且在识别患者状态方面的准确度提高了 1.9 倍。结论：在配置显示器中提供具有清晰可见的趋势和数据可变性的患者信息，可以提高 ICU 护士解释数据的速度和准确性。应用：尽管包括本研究在内的许多研究支持使用配置显示器，但绝大多数 ICU 监控显示器仍然以数字格式显示临床数据。在临床监测中引入配置显示器有可能提高患者的安全。
Objective:The objective was to evaluate a configural vital signs (CVS) display designed to support rapid detection and identification of physiological deterioration by graphically presenting patient vital signs data.Background:Current display technology in the intensive care unit (ICU) is not optimized for fast recognition and identification of physiological changes in patients. To support nurses more effectively, graphical or configural vital signs displays need to be developed and evaluated.Method:A CVS display was developed based on findings from studies of the cognitive work of ICU nurses during patient monitoring. A total of 42 ICU nurses interpreted data presented either in a traditional, numerical format (n = 21) or on the CVS display (n = 21). Response time and accuracy in clinical data interpretation (i.e., identification of patient status) were assessed across four scenarios.Results:Data interpretation speed and accuracy improved significantly in the CVS display condition; for example, in one scenario nurses required only half of the time for data interpretation and showed up to 1.9 times higher accuracy in identifying the patient state compared to the numerical display condition.Conclusion:Providing patient information in a configural display with readily visible trends and data variability can improve the speed and accuracy of data interpretation by ICU nurses.Application:Although many studies, including this one, support the use of configural displays, the vast majority of ICU monitoring displays still present clinical data in numerical format. The introduction of configural displays in clinical monitoring has potential to improve patient safety.
