Objective. The aim of this study is to evaluate the consistency of pattern identification (PI), a set of diagnostic indicators used by traditional Korean medicine (TKM) clinicians. Methods. A total of 168 stroke patients who were admitted into oriental medical university hospitals from June 2012 through January 2013 were included in the study. Using the PI indicators, each patient was independently diagnosed by two experts from the same department. Interobserver consistency was assessed by simple percentage agreement as well as by kappa and AC1 statistics. Results. Interobserver agreement on the PI indicators (for all patients) was generally high: pulse diagnosis signs (AC1 = 0.66-0.89); inspection signs (AC1 = 0.66-0.95); listening/smelling signs (AC1 = 0.67-0.88); and inquiry signs (AC1 = 0.62-0.94). Conclusion. In four examinations, there was moderate agreement between the clinicians on the PI indicators. To improve clinician consistency (e.g., in the diagnostic criteria used), it is necessary to analyze the reasons for inconsistency and to improve clinician training.
目的。本研究旨在评估模式识别（PI）的一致性，PI 是传统韩国医学（TKM）临床医生使用的一组诊断指标。
方法。本研究共纳入了 2012 年 6 月至 2013 年 1 月期间入住东方医学大学医院的 168 名中风患者。使用 PI 指标，由同一科室的两位专家对每位患者进行独立诊断。通过简单百分比一致性以及 Kappa 和 AC1 统计评估观察者间的一致性。
结果。PI 指标的观察者间一致性（所有患者）通常较高：脉象诊断征象（AC1=0.66-0.89）；望诊征象（AC1=0.66-0.95）；闻诊/听诊征象（AC1=0.67-0.88）；问诊征象（AC1=0.62-0.94）。
结论。在四项检查中，临床医生在 PI 指标上的一致性为中等。为了提高临床医生的一致性（例如，在使用的诊断标准方面），有必要分析不一致的原因并改进临床医生的培训。
