脑梗死急性期OCSP分型的信度评价

Evaluation of reliability of Oxfordshire Community Stroke Project classification of acute ischemic stroke.

目的 评价脑梗死急性期OCSP分型的观察者间信度。方法 2名神经科医生分别将连续就医、首次发生的急性脑梗死 1 1 0例分为 4个OCSP亚型。结果 2名神经科医生分型的一致性为尚好 (kappa =0 3 9,95 %CI=0 3 0～ 0 48)至中度 (kappa =0 42 ,95 %CI=0 3 3～ 0 5 1 )。而对某些神经体征检查的一致性较差。结论 OCSP分型在脑梗死急性期的观察者间信度较为满意 ,是一种简便、实用的临床分型工具 。

Objective To evaluat interobserver reliability of Oxfordshire Community Stroke Project(OCSP) classification in acute phase of cerebral infarction. Methods Two neurologists respectively classified 110 cases of consecutive patient with a first ever cerebral infarction admitted to emergency room or hospital, based on the criteria of OCSP classification. Results The interobserver agreement of OCSPclassification was fair ( Kappa =0.39, 95%CI=0 30～0 48) to moderate( Kappa =0.42, 95%CI=0 33～0 51). Agreement of some neurological sign evaluated was poor. Conclusions The OCSP classification was a simple and practical clinical tool. Its interobserver reliability in acute phase of cerebral infarction was satisfactory. Variation of neurological sign evaluated could result in disagreement of the subtypes of infaction.
