Abstract

BACKGROUND AND PURPOSE

A perceived weakness of the modified Rankin Scale is potential for interobserver variability. We undertook a systematic review of modified Rankin Scale reliability studies.

METHODS

Two researchers independently reviewed the literature. Crossdisciplinary electronic databases were interrogated using the following key words: Stroke*; Cerebrovasc*; Modified Rankin*; Rankin Scale*; Oxford Handicap*; Observer variation*. Data were extracted according to prespecified criteria with decisions on inclusion by consensus.

RESULTS

From 3461 titles, 10 studies (587 patients) were included. Reliability of modified Rankin Scale varied from weighted kappa=0.95 to kappa=0.25. Overall reliability of mRS was kappa=0.46; weighted kappa=0.90 (traditional modified Rankin Scale) and kappa=0.62; weighted kappa=0.87 (structured interview).

CONCLUSION

There remains uncertainty regarding modified Rankin Scale reliability. Interobserver studies closest in design to large-scale clinical trials demonstrate potentially significant interobserver variability.

摘要

背景与目的

改良Rankin量表的一个公认弱点是观察者间存在变异性。我们对改良Rankin量表的可靠性研究进行了系统评价。

方法

两名研究人员独立检索文献。使用以下关键词对跨学科电子数据库进行检索：中风*；脑血管*；改良Rankin*；Rankin量表*；牛津残疾*；观察者变异*。根据预先设定的标准提取数据，并通过共识决定纳入研究。

结果

从3461篇标题中筛选出10项研究（587例患者）。改良Rankin量表的可靠性从加权kappa=0.95到kappa=0.25不等。改良Rankin量表的总体可靠性为kappa=0.46；加权kappa=0.90（传统改良Rankin量表），kappa=0.62；加权kappa=0.87（结构化访谈）。
