The authors derived a clinical score to predict mortality in status epilepticus (SE) from analysis of a retrospective SE cohort, using four variables available at presentation: history of seizures, age, seizure type, and consciousness impairment. Validation on a small prospective SE series (34 patients) resulted in sensitivity, 1.000; specificity, 0.643; negative predictive value, 1.000; and unweighted accuracy, 0.822. This simple clinical score may reliably identify patients surviving after SE.
