We evaluated the feasibility and the reliability of remote stroke severity quantification in the prehospital setting using the Unassisted TeleStroke Scale (UTSS) via a telestroke ambulance system and a fourth-generation mobile network.
The technical feasibility and the reliability of the UTSS were studied in healthy volunteers mimicking 41 stroke syndromes during ambulance transportation.
Except for 1 issue, high-quality telestroke assessment was feasible in all scenarios. The mean examination time for the UTSS was 3.1 minutes (SD, 0.4). The UTSS showed excellent intrarater and interrater variability (ρ=0.98 and 0.97; P<0.001), as well as excellent internal consistency and rater agreement. Adequate concurrent validity can be derived from the strong correlation between the UTSS and the National Institutes of Health Stroke Scale (ρ=0.90; P<0.001).
Remote assessment of stroke severity in fast-moving ambulances using a system dedicated to prehospital telemedicine, 4G technology, and the UTSS is feasible and reliable.
我们评估了使用远程卒中量表（Unassisted TeleStroke Scale，UTSS）通过远程卒中救护车系统和第四代移动网络在院前环境中进行远程卒中严重程度定量的可行性和可靠性。
在救护车转运期间，健康志愿者模拟了 41 种卒中综合征，研究了 UTSS 的技术可行性和可靠性。
除了 1 个问题外，所有情况下都可以进行高质量的远程卒中评估。UTSS 的平均检查时间为 3.1 分钟（SD，0.4）。UTSS 显示出极好的内部一致性和评分者间一致性（ρ=0.98 和 0.97；P<0.001），以及极好的内部一致性和评分者间一致性。UTSS 与国立卫生研究院卒中量表（National Institutes of Health Stroke Scale，NIHSS）之间具有很强的相关性，表明具有足够的同时效度（ρ=0.90；P<0.001）。
使用专门用于院前远程医疗的系统、4G 技术和 UTSS 在快速移动的救护车上进行远程卒中严重程度评估是可行且可靠的。
