Eye tracking technology to improve communication with intubated critical care patients: a randomized study

Abstract

Purpose: Communication with patients undergoing mechanical ventilation in the intensive care unit represents a challenge. The aims of the study were (1) to describe communication difficulties related to mechanical ventilation as experienced by caregivers and patients, and (2) to compare the use of a conventional low-tech communication board and a high-tech eye tracking technology-based device in order to improve communication effectiveness of mechanically ventilated patients in intensive care. Methods: This prospective study consisted of a descriptive cross-sectional part describing the communication difficulties in the intensive care unit and an experimental randomized crossover part comparing the use of two technologically opposed augmentative and alternative communication interfaces. A mixed method approach was applied with a quantitative primary method and a qualitative complementary method. Results: A total of 101 caregivers and 44 patients participated. Regarding the descriptive part, the communication difficulty analysis confirmed that mechanical ventilation constitutes a major problem in patient-caregiver communication. Regarding the quantitative experimental part, the treatment effects on transmitted messages quantity (2 median messages per exchange for the board versus 4 median messages per exchange for the eye tracking, p < 0.0001), success rate (80% for the board versus 100% for the eye tracking, p < 0.05) and patient satisfaction (68% negative satisfaction level for the board versus 100% positive satisfaction level for eye tracking, p < 0.0001) were significant. Regarding the qualitative experimental part, the communication content covered 8 themes for the board compared to 9 themes for the eye tracking and he use difficulties included 4 categories for the board as well as for the eye tracking. Conclusion: The eye tracking device may improve communication effectiveness of mechanically ventilated patients compared to the conventional communication board, both quantitatively and qualitatively.

Research on Construction Technology of Communication Mechanical and Electrical Engineering

“…This will hurt the overall construction quality of the engineering machinery, greatly reducing the accuracy of mechanical operation. However, if BIM technology is used to correct Voice of the Publisher basic parameters, It can greatly improve the accuracy of data analysis and also select the correct mechanical equipment according to the analysis results (Szymkowicz et al, 2023;Yang et al, 2022). Thirdly, materials and costs.…”
