Table 3.
Delayed seizure rate and associated odds ratios as a function of admission diagnosis and early EEG findings
Abbreviations: AMS = altered mental status; cEEG = continuous EEG; CVA = cerebrovascular accident; HIE = hypoxic-ischemic encephalopathy; ICH = intracerebral hemorrhage; Nsgy = post neurosurgical procedure; SAH = subarachnoid hemorrhage; TBI = traumatic brain injury; TME = toxic-metabolic encephalopathy.
Data given as % (N/total); cohort consists of patients without seizures during the first 30 minutes of cEEG monitoring. Only the presence of early epileptiform discharges was found to be a statistically significant (i.e., p < 0.05) predictor of subsequent seizures on univariate analysis (p < 0.001).
Ninety-five percent confidence interval for odds ratio for epileptiform discharges: 2.3–31.2.
