Abstract: Objective To assess the reliability of ischemic stroke subtype classification using the A-S-C-Ocriteria, Trial of Org 10172 in Acute Stroke Treatment (TOAST) criteria and Chinese IschemicStroke Subclassfication (CISS) criteria.Methods A hundred acute ischemic stroke patients were consecutively recruited into this study.Two raters were invited to assess the etiological subclassification using the A-S-C-O criteria,TOAST criteria and CISS criteria. The data was analyzed by the statistics software of SPSS 17.0.Results The value of Kappa about the A-S-C-O classification’s reliability was 0.504, (P <0.001).The value of Kappa about the TOAST classification’s reliability was 0.769, (P <0.001). The value ofKappa about the CISS classification’s reliability was 0.710, (P <0.001).Conclusion The reliability of the A-S-C-O classification was moderate, the reliability of theTOAST classification and the CISS classification were both good.

摘要： 目的 评定缺血性卒中A-S-C-O分型、急性卒中治疗Org10172试验（trial of org 10172 in acutestroke treatment，TOAST）分型及中国缺血性卒中亚型（Chinese ischemic stroke subclassfication，CISS）的信度检验。方法 连续收集我院新发缺血性卒中患者100例，由两位研究者对其进行分型，对3种分型分别进行信度检验。结果 本研究A-S-C-O分型的Kappa值为0.504，P <0.01；TOAST分型的Kappa值为0.769，P <0.01；CISS分型的Kappa值为0.710，P <0.01。结论 A-S-C-O分型的一致性中等，TOAST分型及CISS分型的一致性良好。【关键词】 脑梗死；A-S-C-O分型；TOAST分型；CISS分型；信度
