Causes of death in patients with status epilepticus.

ABSTRACT

BACKGROUND: Status epilepticus (SE) is a neurological disorder that affects to the high mortality risk. Several studies reported predictors of mortality in SE; actual causes of death in hospital and out of hospital are limited. This study aimed to describe the case fatality and the causes of death in patients with SE. METHODS: This was a descriptive study using the data collected in the national data of the Universal Coverage Scheme in Thailand during the fiscal year 2005 to 2015. Patients who admitted to hospitals and diagnosed as SE were included. The vital status of patients with SE was linked with the Ministry of the Interior and was classified into three phases in-hospital, short-term, and long-term. RESULTS: Among 24,802 patients with SE, 1861 (7.5%) died in hospital, 1910 (7.7%) died within 30 days after hospital discharge, and 4906 (19.8%) died after 30 days. In-hospital death, SE complications (45.9%), seizure (19.6%), and comorbidities (15.4%) were the three common causes of death. While the common causes in short-term and long-term mortality were SE complications (27.7% and 31.0%), comorbidities (28.1% and 26.7%), and other causes (22.4% and 21.9%). CONCLUSION: Status epilepticus complications and comorbidities were the common cause of death in patients with SE for all of three periods.
