目的：本研究探讨了EEG专家间一致性（伊拉）在连续ICU EEG记录中识别癫痫发作和周期性放电（PD）的方法：8名委员会认证的EEG专家独立识别30个1 h EEG片段中的癫痫发作和PD，这些片段选自3个医学中心的ICU EEG记录。伊拉在癫痫发作和PD鉴定之间进行了比较，以及在通过重症监护EEG监测研究联盟（CCEMRC）开发的ICU EEG认证测试的评估者组之间进行了比较。结果：与PD相比，kappa和基于事件的伊拉统计显示癫痫发作鉴定的平均值更高（k = 0.58 vs. 0.38; p < 0.001）。组的评分者对谁都通过了ICU EEG认证测试有一个显着较高的平均伊拉评分者对中，既没有通过test.Conclusions：IRA之间的伊拉是显着较高的识别电图癫痫发作相比，PD。额外的指令，如由CCEMRC开发的培训模块和认证测试，可以提高这个伊拉.Significance：这项研究表明，更多的分歧，在标签的PD相比，癫痫发作。这可以通过关于标准EEG命名法的教育来改善。由Elsevier爱尔兰有限公司代表国际临床神经生理学联合会发布。
Objective: This study investigated inter-rater agreement (IRA) among EEG experts for the identification of electrographic seizures and periodic discharges (PDs) in continuous ICU EEG recordings.Methods: Eight board-certified EEG experts independently identified seizures and PDs in thirty 1-h EEG segments which were selected from ICU EEG recordings collected from three medical centers. IRA was compared between seizure and PD identifications, as well as among rater groups that have passed an ICU EEG Certification Test, developed by the Critical Care EEG Monitoring Research Consortium (CCEMRC).Results: Both kappa and event-based IRA statistics showed higher mean values in identification of seizures compared to PDs (k = 0.58 vs. 0.38; p < 0.001). The group of rater pairs who had both passed the ICU EEG Certification Test had a significantly higher mean IRA in comparison to rater pairs in which neither had passed the test.Conclusions: IRA among experts is significantly higher for identification of electrographic seizures compared to PDs. Additional instruction, such as the training module and certification test developed by the CCEMRC, could enhance this IRA.Significance: This study demonstrates more disagreement in the labeling of PDs in comparison to seizures. This may be improved by education about standard EEG nomenclature. Published by Elsevier Ireland Ltd. on behalf of International Federation of Clinical Neurophysiology.
