More than one in six patients with status epilepticus are readmitted after hospital discharge


 

REPORTING FROM AAN 2019

ā€“ About 17% of patients discharged from a hospital after treatment for generalized convulsive status epilepticus are readmitted within 30 days, according to research presented at the annual meeting of the American Academy of Neurology. It is possible to identify patients at high risk of readmission, which could allow neurologists to reduce their clinical and economic burden, said the investigators.

Status epilepticus is a major neurologic emergency. Patients often have significant disability and may represent a burden on their families and on the health care system. To identify independent predictors of 30-day hospital readmission among patients discharged after generalized convulsive status epilepticus, Mohamad Rahwan, MD, a neurologist at the Medical University of South Carolina, Charleston, and colleagues examined data from the 2014 Nationwide Readmission Database.

The investigators included adults with a primary discharge diagnosis of generalized convulsive status epilepticus, identified by the ICD-9-CM code 345.3, in their study. Patients who died during hospitalization, had missing information on the length of stay, or were discharged in December 2014 were excluded from analysis. Dr. Rahwan and colleagues calculated the overall 30-day readmission rate for the sample and compared prespecified groups by their 30-day readmission status. They performed multiple logistic regression analysis to identify independent predictors of 30-day readmission, adjusting for potential confounders.

In all, 14,562 adults were discharged with a diagnosis of generalized convulsive status epilepticus. Of this population, 2,520 patients (17.3%) were readmitted within 30 days. Multivariate logistic regression analysis indicated that patients discharged against medical advice (odds ratio, 1.45), those discharged to short-term hospital (OR, 1.39), those with comorbid conditions (OR for Charlson Comorbidity Index of 1, 1.12; OR for Charlson Comorbidity Index of 2 or greater, 1.32), and those with a length of stay exceeding 6 days (OR, 1.42) had a greater risk of 30-day readmission. The researchers observed an inverse association for patients aged 45 years or older and for those in high-income households. ā€œGreater attention to high-risk subgroups may identify opportunities to ameliorate the clinical and economic burden of early readmissions after generalized convulsive status epilepticus,ā€ said the researchers.

The researchers had no disclosures.
