摘要 目的分析基层医院院前急救人员对当地社区拟似卒中患者应用洛杉矶院前卒中筛查量表(LAPSS)的现况及准确性。方法以唐山市五县区基层社区人群中的拟似卒中患者为评估对象,各县区县级医院120网络院前人员为评估实施者,对社区拟似卒中求救患者在院前进行LAPSS评估,与到达医院后确诊诊断进行对比分析,计算灵敏度、特异度、总准确率、误诊率、漏诊率、Youdon指数、阳性预测值、阴性预测值。结果前瞻性登记自2008年8月一2012年5月院前拟似卒中患者2000例,最终1979例有效病例纳入统计分析,其中男1087例(54.9%),女892例(45.1%)。最终,院前LAPSS筛查为"是"有1253例(63.3%),"否"有726例(36.7%)。而出院诊断为脑梗死645例(32.6%),脑出血687例(34.7%),蛛网膜下腔出血109例(5.5%),脑栓塞89例(4.5%),TIA及其他非卒中449例(22.7%)。经统计分析,院前LAPSS筛查灵敏度、特异度、总正确率、误诊率、漏诊率、Youden指数、阳性预测值、阴性预测值分别为73.9%、72.8%、73.7%、27.2%、26.1%、46.7%、90.3%、45.0%。计算Kappa值=0.384。另外,对卒中进行分类统计后显示,缺血性脑卒中与脑出血的LAPSS阳性率明显高于蛛网膜下腔出血及非卒中(73.6%、80.6%、33.9%、27.2%)。结论院前人员运用LAPSS可提高院前卒中诊断水平,仍需进一步改进以区分脑出血性与缺血性卒中,避免医疗资源浪费。
