| Summary: | Objective:The aim of this study was to investigate the diagnostic utility of routine electroencephalogram and video electroencephalogram monitoring.Methods:We performed a retrospective analysis on patients admitted to our video electroencephalogram monitoring unit. The yield of routiene electroencephalogram and video electroencephalogram monitoring was compared and assessed with the detection of epileptiform discharges.Results:Out of 191 patients, the epileptiform discharges found in routiene electroencephalogram and video electroencephalogram monitoring were 39 (21%) and 99 (52%), respectively. The yield of epileptiform discharges differed significantly between video electroencephalogram monitoring and routiene electroencephalogram (P < .001). While the epileptiform discharges detection rate (95% CI) was 0.29 (0.25-0.46) for routiene electroencephalogram, it was 0.93 (0.86-0.97) for video electroencephalogram monitoring.Conclusion:Compared to routiene electroencephalogram, video electroencephalogram monitoring is superior in detecting epileptiform discharges.
