BACKGROUND
The Oxfordshire Community Stroke Project (OCSP) and Trial of ORG 10172 in Acute Stroke Treatment (TOAST) classifications are widely used for the assessment of major ischaemic stroke. We explored their intra- and inter-observer reliability in the classification of outpatient minor stroke.
METHODS
Four physicians of differing seniority and training backgrounds classified minor stroke using clinical data from 90 patients.
RESULTS
For both the OCSP and TOAST classifications, the intra-observer reliability varied from moderate to excellent (kappa = 0.48-0.83). The inter-observer reliability was good (kappa = 0.64) for the OCSP and moderate (kappa = 0.42) for the TOAST. Thus, neither classification was consistently reliable.
CONCLUSIONS
Our results may reflect the limited validity of these classifications in a typical minor stroke outpatient population and variable observer expertise.
背景
牛津郡社区卒中项目（OCSP）分类法和急性卒中治疗中ORG 10172试验（TOAST）分类法广泛用于评估主要缺血性卒中。我们探讨了它们在门诊小卒中分类中的观察者内和观察者间可靠性。
方法
四位资历和培训背景不同的医生利用90例患者的临床数据对小卒中进行分类。
结果
对于OCSP和TOAST分类法，观察者内可靠性从中度到优不等（kappa = 0.48 - 0.83）。OCSP的观察者间可靠性良好（kappa = 0.64），而TOAST的观察者间可靠性为中度（kappa = 0.42）。因此，两种分类法均非始终可靠。
结论
我们的结果可能反映了这些分类法在典型的门诊小卒中人群中的有效性有限以及观察者专业知识的差异。
