title: A practical analysis of computer based seizure detection during continuous video-EEG monitoring.
abstract: Computer based seizure detection (CSD) systems improve the efficiency of CCTV-EEG monitoring by capturing epileptic seizures which would have otherwise been missed. We prospectively evaluated the yield of a commercial CSD system in 83 consecutive CCTV-EEG admissions. All seizures were coded as to the method of detection. The percentage of seizures detected only by CSD was calculated for each patient and the impact on length of hospital stay was estimated. Overall, 33% of epileptic seizures were signaled by the patient, 45% were directly observed by family or medical personnel, and 22% were captured only by CSD. Forty admissions (48%) had at least one seizure captured only by CSD. The majority of these events were clinical and electrographic seizures (73%) and the remainder were purely electrographic. Five admissions concluded with all seizures captured only by CSD. We estimated an average saving of 1.3 hospital days per admission, based on the percentage of seizures captured only by CSD.
