The study measured whether nurses' situation awareness would increase and task completion time decrease when they used an integrated information display compared to traditional displays for medication management, patient awareness and team communication.
The Burn Trauma Intensive Care Unit (BTICU) at the University Hospital, University of Utah Health Science Center, Salt Lake City, Utah, USA.
12 experienced BTICU nurses.
Situation awareness (accuracy of the participants' answer) and task completion time (response time from seeing the question to submitting the answer) were measured using paper prototypes of both displays.
Counter-balanced (on display order), repeated-measures design.
Nurses had a higher situation awareness when using the integrated display, with an overall accuracy of 85.3% compared to 61.8% with the traditional displays (odds ratio 3.61, P<.001, 95% CI=2.34…5.57). Task completion times were nearly half with integrated displays compared to traditional displays (median 26.0 and 42.1s, hazard ratio 2.31, P<.001, CI=1.83…2.93).
An integrated ICU information display increased nurses' situation awareness and decreased task completion time. Information integration has the potential to decrease errors, increase nurses' productivity and may allow nurses to react faster to a patient's clinical needs. Bidirectional device communication is needed for these displays to achieve full potential in improving patient safety.
本研究旨在比较整合信息显示与传统药物管理、患者意识和团队沟通显示在提高护士情境意识和缩短任务完成时间方面的效果。
美国犹他大学健康科学中心盐湖城大学医院烧伤创伤重症监护病房（BTICU）。
12 名经验丰富的 BTICU 护士。
使用两种显示方式的纸质原型来测量情境意识（参与者答案的准确性）和任务完成时间（从看到问题到提交答案的反应时间）。
平衡（显示顺序）、重复测量设计。
与传统显示相比，护士使用整合显示时情境意识更高，整体准确率为 85.3%，而传统显示准确率为 61.8%（优势比 3.61，P<.001，95%CI=2.34…5.57）。与传统显示相比，使用整合显示时任务完成时间几乎缩短一半（中位数分别为 26.0 和 42.1s，危害比 2.31，P<.001，CI=1.83…2.93）。
整合 ICU 信息显示提高了护士的情境意识，缩短了任务完成时间。信息整合有可能减少错误，提高护士的工作效率，并使护士能够更快地对患者的临床需求做出反应。这些显示要充分发挥提高患者安全性的潜力，需要双向设备通信。
