ABSTRACT
BACKGROUND: Seizures are a frequent complication after intracerebral hemorrhage (ICH). The CAVE score was developed in Europeans to predict late seizures after ICH. Given the higher incidence of ICH in Asians, we aimed to develop and validate a clinical scoring tool for predicting post-ICH late seizures in Chinese.
METHODS: We retrospectively included patients admitted with ICH to a major stroke center in Shandong province, China, in the derivation cohort, who were followed up for occurrence of late seizures (more than seven days after ICH). We applied Cox regression model to identify significant clinical factors which were used to derive a predictive scoring model. The performance of this model was compared with CAVE, and validated in a separate cohort of patients with ICH admitted to another stroke center.
RESULTS: In the derivation cohort (n = 602; median age 65 years; 57 % male；median follow up 24 months), 47 (7.8 %) patients had late seizures during follow up. Four significant risk factors were identified and selected to derive the LANE score (Lobar hemorrhage, Age <65 years, NIHSS score ≥15, Early seizures). The total possible points ranged from 0 to 6, corresponding to positive predictive values of 10.1%-100%, and negative predictive values of 96.8%-92.2%, respectively. The c-statistics of the LANE score in the derivation cohort and validation cohort (n = 521) were 0.83 and 0.78, respectively, while those of the CAVE score were 0.81 and 0.74, respectively.
CONCLUSION: We have developed and validated a clinical scoring tool for predicting late seizures after ICH in Chinese. This tool may be used to identify high risk patients for closer monitoring and clinical trials of therapies to prevent post-ICH epilepsy in the future.
