Abstract
Background: To investigate the influential factors of complications on prognosis of patients with status epilepticus, modify the Complication Burden Index （CBI）into the Rankin CBI（RCBI）, and analyze its practicability in status epilepticus in western China. Method: A total of 396 patients with status epilepticus were studied from December 2016 to January 2019 in West China Hospital. The clinical data were collected, including demographic characteristics, status epilepticus characteristics. Statistical analysis was performed using SPSS 22.0 and MedCalc ROC，and logistic regression was used to analyze the influencing factors of hospitalization death and poor prognosis (GOS scale is 1-3). Results: Of the 396 patients with status epilepticus included in the study, 43 (10.9%) died in hospital and 114 (28.8%) had poor prognosis. Using ROC curve analysis, when RCBI > 3, the area under the ROC curve of hospitalization death was 0.914 , p < 0.0001; When RCBI > 3, the area under ROC curve for poor prognosis was 0.882, p < 0.0001. There were 327 people with convulsive status epilepticus, including 41 deaths. When RCBI>3, the area under the hospital mortality curve was 0.915 (p<0.0001). A total of 100 patients had a poor prognosis. When RCBI>3, the area under the poor prognosis curve was 0.867 (p<0.0001). Conclusions: The hospital mortality rate of patients with status epilepticus is 10.9%. RCBI >3 points had a certain significance for predicting hospitalization death and poor prognosis of status epilepticus. There were no significant differences in RCBI scales for convulsive status epilepticus and non-convulsive status epilepticus.
