Communication of caregivers and relatives to patients is a major difficulty in intensive care units (ICU). Patient’s comprehension capabilities are variable over time and traditional comprehension tests cannot be implemented. Our purpose was to evaluate an oral comprehension test adapted for its automatic implementation using eye-tracking technology among ICU patients. Prospective bi-centric cohort study was conducted on 60 healthy volunteers and 53 ICU patients. Subjects underwent an oral comprehension test using an eye-tracking device: Their results and characteristics were collected. The total duration of the test was 2 and a half minutes. While performing the test, 48 patients (92%) received invasive ventilation. Among healthy volunteers, the median rate of right answers was very high (93% [interquartile range 87, 100]), whereas it was lower (33% [20, 67]) for patients. For both groups, a significantly lower right answers rate was observed with advancing age (67% [27, 80] vs. 27% [20, 38] among patients and 93% [93, 100] vs. 87% [73, 93] among healthy volunteers, below and above 60 years of age, respectively) and in case of lack of a bachelor’s degree (60% [38, 87] vs. 27% [20, 57] among patients and 93% [93, 100] vs. 87% [73, 93] among healthy volunteers). For patients, the higher the severity of disease was, the lower the rate of correct answers was. The eye-tracking-adapted comprehension test is easy and fast to use among ICU patients, and results seem coherent with various potential levels of comprehension as hypothesized in this study.

在重症患者和健康志愿者中使用基于眼动追踪的创新设备评估口语理解能力：一项队列研究

护理人员和亲属与患者的沟通是重症监护病房 (ICU) 的主要困难。患者的理解能力随时间变化，传统的理解测试无法实施。我们的目的是评估适用于在 ICU 患者中使用眼动追踪技术自动实施的口语理解测试。对 60 名健康志愿者和 53 名 ICU 患者进行了前瞻性双中心队列研究。使用眼动仪对受试者进行口语理解测试：收集他们的结果和特征。测试的总持续时间为 2 分半钟。在进行测试时，48 名患者 (92%) 接受了有创通气。在健康志愿者中，正确答案的中位数非常高（93% [四分位数间距 87, 100]），而患者则较低 (33% [20, 67])。对于两组，随着年龄的增长，正确答案率显着降低（67% [27, 80] vs. 27% [20, 38] 患者和 93% [93, 100] vs. 87% [73, 93 ] 在健康志愿者中，分别为 60 岁以下和 60 岁以上）和缺乏学士学位的情况（60% [38, 87] vs. 27% [20, 57] 和 93% [93, 100 ] 对比 87% [73, 93] 在健康志愿者中）。对于患者来说，疾病的严重程度越高，答对率越低。眼动追踪适应性理解测试在 ICU 患者中使用起来简单快捷，结果似乎与本研究假设的各种潜在理解水平一致。随着年龄的增长，正确答案率显着降低（患者为 67% [27, 80] 对 27% [20, 38]，健康志愿者为 93% [93, 100] 对 87% [73, 93] ，分别为 60 岁以下和 60 岁以上）以及缺乏学士学位的情况（60% [38, 87] vs. 27% [20, 57] 患者和 93% [93, 100] vs. 87 % [73, 93] 在健康志愿者中）。对于患者来说，疾病的严重程度越高，答对率越低。眼动追踪适应性理解测试在 ICU 患者中使用起来简单快捷，结果似乎与本研究假设的各种潜在理解水平一致。随着年龄的增长，正确答案率显着降低（患者为 67% [27, 80] 对 27% [20, 38]，健康志愿者为 93% [93, 100] 对 87% [73, 93] ，分别为 60 岁以下和 60 岁以上）以及缺乏学士学位的情况（60% [38, 87] vs. 27% [20, 57] 患者和 93% [93, 100] vs. 87 % [73, 93] 在健康志愿者中）。对于患者来说，疾病的严重程度越高，答对率越低。眼动追踪适应性理解测试在 ICU 患者中使用起来简单快捷，结果似乎与本研究假设的各种潜在理解水平一致。分别）和缺乏学士学位的情况（60% [38, 87] vs. 27% [20, 57] 患者和 93% [93, 100] vs. 87% [73, 93] 健康志愿者). 对于患者来说，疾病的严重程度越高，答对率越低。眼动追踪适应性理解测试在 ICU 患者中使用起来简单快捷，结果似乎与本研究假设的各种潜在理解水平一致。分别）和缺乏学士学位的情况（60% [38, 87] vs. 27% [20, 57] 患者和 93% [93, 100] vs. 87% [73, 93] 健康志愿者). 对于患者来说，疾病的严重程度越高，答对率越低。眼动追踪适应性理解测试在 ICU 患者中使用起来简单快捷，结果似乎与本研究假设的各种潜在理解水平一致。
