Abstract

Background/objective

Prior studies have not directly evaluated the association between number of antiseizure medications (ASMs) and neurological outcomes. The objective of this study was to evaluate the association between the number of ASMs administered to patients in refractory SE and modified Rankin Scale (mRS) score at discharge.

Methods

This was a retrospective cohort analysis of adults with SE from 2020 to 2023. Exclusion criteria included pregnancy, post-arrest myoclonus, and ≤ 2 non-benzodiazepine ASMs during admission. Patients were grouped by number of non-benzodiazepine ASMs received during admission (2, 3, or ≥4 ASMs). The primary outcome was mRS score at discharge.

Results

The study included 287 patients (2 ASMs: 86, 3 ASMs: 82, ≥4 ASMs: 119), predominantly white (52.6 %) non-Hispanic (92.0 %) males (57.8 %) aged 55 – 60 years. Most patients had a history of epilepsy (73.9 %) and presented with convulsive SE (66.9 %). Patients receiving ≥ 4 ASMs had a higher median mRS score (4 vs. 1 vs. 1, p = 0.0001) and higher level of care at discharge (p = 0.0001) than comparators. Hospital and intensive care unit lengths of stay were longer in the ≥ 4 ASM group (12.2 and 6.0 days, respectively) than in comparator groups (2 ASMs: 5.5 and 2.2 days; 3 ASMs: 5.8 and 2.8 days; p < 0.001).

Conclusions

The results of this study suggest that patients requiring ≥ 4 ASMs for treatment of SE have worse neurological outcomes. These results may inform treatment preferences for refractory SE and provide data for risk-benefit discussions.

期刊介绍： Epilepsy Research provides for publication of high quality articles in both basic and clinical epilepsy research, with a special emphasis on translational research that ultimately relates to epilepsy as a human condition. The journal is intended to provide a forum for reporting the best and most rigorous epilepsy research from all disciplines ranging from biophysics and molecular biology to epidemiological and psychosocial research. As such the journal will publish original papers relevant to epilepsy from any scientific discipline and also studies of a multidisciplinary nature. Clinical and experimental research papers adopting fresh conceptual approaches to the study of epilepsy and its treatment are encouraged. The overriding criteria for publication are novelty, significant clinical or experimental relevance, and interest to a multidisciplinary audience in the broad arena of epilepsy. Review articles focused on any topic of epilepsy research will also be considered, but only if they present an exceptionally clear synthesis of current knowledge and future directions of a research area, based on a critical assessment of the available data or on hypotheses that are likely to stimulate more critical thinking and further advances in an area of epilepsy research.
