The study aimed to validate and compare the Siriraj score, Guy's hospital score, Greek score, and Besson score in a group of stroke patients.
We assessed the stroke scores and compared them to computed tomography (CT) scan of brain.
Two hundred stroke patients (129 ischemic stroke) were included. For ischemic stroke, sensitivity and specificity were 71% and 92% (Siriraj score), 73% and 98% (Greek score), 59% and 87% (Guy's hospital score), and 65% and 98% (Besson score), respectively. For intracranial hemorrhage, sensitivity and specificity were 84% and 89% (Siriraj score), 80% and 99% (Greek score), and 63% and 95% (Guy's hospital score), respectively. Using receptor operating characteristic curve, the greatest area under the curve was obtained for Greek score (0.973). For bedside accurate and safe diagnosis of ischemic stroke, the best cut off was for Greek score (1.5) which identified 47% of ischemic stroke patients.
The Greek score appears as the single best score. Using the newly developed discriminant cut off value; a substantial number of patients may be started with anti-platelet therapy while awaiting CT scan of brain.
本研究旨在验证并比较一组中风患者的诗里拉吉评分、盖伊医院评分、希腊评分和贝松评分。
我们评估了中风评分，并将其与脑部计算机断层扫描（CT）结果进行比较。
纳入了200例中风患者（129例缺血性中风）。对于缺血性中风，敏感性和特异性分别为：诗里拉吉评分为71%和92%，希腊评分为73%和98%，盖伊医院评分为59%和87%，贝松评分为65%和98%。对于颅内出血，敏感性和特异性分别为：诗里拉吉评分为84%和89%，希腊评分为80%和99%，盖伊医院评分为63%和95%。使用受试者工作特征曲线，希腊评分获得的曲线下面积最大（0.973）。对于床边准确且安全地诊断缺血性中风，希腊评分（1.5）的最佳截断值可识别47%的缺血性中风患者。
希腊评分似乎是最佳评分。使用新制定的判别截断值，大量患者在等待脑部CT扫描时可开始接受抗血小板治疗。
