概括
电子中风人工智能工具显著减少了内血管血栓切除术 (EVT) 转诊的门入门出门时间. 这种人工智能支持可能会改善患者的治疗结果,表明中风治疗速度更快.
科学领域:
- 神经学 神经学
- 医疗成像医学成像
- 医疗信息学 医疗信息学
背景情况:
- 在急性中风中,早期识别大血管封闭 (LVO) 对内血管血栓切除 (EVT) 至关重要.
- 滴送模型需要从急性中风中心 (ASC) 快速转诊到综合性中风中心 (CSC).
- 人工智能 (AI) 决策支持工具正在出现,以加快LVO检测.
研究的目的:
- 评估实施e-Stroke AI决策支持软件的影响.
- 评估超急性中风途径中的过程指标和患者结果的变化.
- 为了确定AI在英国ASC环境中的有效性.
主要方法:
- 追溯队列研究,比较AI实施前和后的实施时期 (2019年1月 - 2021年3月).
- 时间窗口的分析,包括门入门出门 (DIDO) 和门到推时间.
- 修改的兰金得分 (mRS) 用于评估患者在3个月后的残疾.
主要成果:
- 显著减少AI实施后的平均DIDO时间 (141到79分钟,p<0.001) 和门到推时间 (71到44分钟,p=0.01).
- 3个月后达到mRS 0-2的患者比例增加 (16%对48%,p=0.04).
- 表明功能结果有所改善,但由于样本大小,需要谨慎解释.
结论:
- e-Stroke AI显著减少了 DIDO 时间,表明更快的图像解释和 EVT 转介.
- 人工智能工具显示了改善患者在EVT后的功能独立性的潜力.
- 需要进行更大规模的前性研究来证实可通用性和广泛的有效性.
