Prospective evaluation of interrater agreement between EEG technologists and neurophysiologists.

ABSTRACT: We aim to prospectively investigate, in a large and heterogeneous population, the electroencephalogram (EEG)-reading performances of EEG technologists. A total of 8 EEG technologists and 5 certified neurophysiologists independently analyzed 20-min EEG recordings. Interrater agreement (IRA) for predefined EEG pattern identification between EEG technologists and neurophysiologits was assessed using percentage of agreement (PA) and Gwet-AC1. Among 1528 EEG recordings, the PA [95% confidence interval] and interrater agreement (IRA, AC1) values were as follows: status epilepticus (SE) and seizures, 97% [96-98%], AC1 kappa = 0.97; interictal epileptiform discharges, 78% [76-80%], AC1 = 0.63; and conclusion dichotomized as "normal" versus "pathological", 83.6% [82-86%], AC1 = 0.71.
