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.
