Abstract:

Objective Constructing a communication system for ICU orotracheally intubated patients based on eye-tracking technology and validating its clinical application effectiveness，to provide references for addressing the communication challenges in orotracheally intubated patients. Methods A convenience sampling method was used to select 68 orotracheally intubated patients admitted to the comprehensive ICU of a tertiary hospital in Guizhou Province from May to October 2024 as the study subjects. They were divided into an experimental group（34 cases） and a control group（34 cases） using a random number table method. The experimental group communicated using an eye-tracking technology-based communication system for ICU orotracheally intubated patients. This system features 6 functions：eye-tracking calibration，voice output，one-touch alarm，keyboard input，needs expression，and system settings，as well as 4 modules：communication interaction，somatic discomfort，scale assessment，and autonomous entertainment. The control group received conventional ICU communication strategies，including interpreting patients’ body language，writing with paper and pen，and using communication picture books. After the intervention，communication barriers，information transmission accuracy，and patient satisfaction were compared between the 2 groups. The experimental group also evaluated the system usability of the communication system. Results The experimental group included 32 cases finally，while the control group included 31 cases. After the intervention，the scores on the ease of communication scale were（15.28±5.43） points in the experimental group and （18.77 ± 4.75） points in the control group. The accuracy of information transmission was（95.39 ± 5.96）% in the experimental group and（74.05 ± 11.14）% in the control group. Patient satisfaction scores were（3.88 ± 0.79） points and（3.35 ± 0.80） points in the experimental and control groups，respectively. The experimental group demonstrated significantly better communication effectiveness，accuracy of information transmission，and patient satisfaction compared to the control group，with all differences being statistically significant（P<0.05）. The experimental group’s score on the System Usability Scale was（79.75 ± 7.17） points. Conclusion The application of an eye-tracking based communication system in ICU orotracheally intubated patients demonstrates a certain degree of innovation and applicability. It can effectively alleviate patients’ communication barriers，thereby offering a novel approach to addressing the communication challenges and enhancing patient satisfaction.

摘要：

目的 构建基于眼动追踪技术的ICU经口气管插管患者沟通系统，并验证该系统的临床应用效果，为解决经口气管插管患者沟通问题提供参考。方法 采用便利抽样法，选取2024年5—10月贵州省遵义市某三级甲等医院综合ICU收治的68例经口气管插管患者为研究对象，通过随机数字表法分为试验组和对照组，每组各34例，试验组采用基于眼动追踪技术的ICU经口气管插管患者沟通系统进行沟通，该系统共有眼动校准、语音输出、一键报警、 键盘输入、需求表达、系统设置6个功能及沟通互动、躯体不适、量表评估、自主娱乐4个模块；对照组采用解读患者肢体语言、纸笔书写、沟通图册等ICU常规沟通方法。干预后，比较两组的沟通障碍程度、信息传递正确率、患者满意度差异，并请试验组评价该沟通系统的可用性。结果 最终试验组纳入32例，对照组纳入31例。干预后，试验组及对照组沟通障碍量表得分别为（15.28±5.43）（18.77±4.75）分；信息传递正确率分别为（95.39±5.96）%和（74.05±11.14）%，患者满意度分别为（3.88±0.79）（3.35±0.80）分，试验组沟通效果、信息传递正确率及患者满意度均优于对照组，差异均具有统计学意义（P<0.05）。试验组系统可用性量表得分为（79.75±7.17）分。结论 在ICU经口气管插管患者中应用基于眼动追踪技术的沟通系统具有一定的可用性和安全性，可有效改善患者的沟通障碍情况，提高患者的满意度。
