    Abstract:
    The identification and characterization of sudden unexpected deaths in epilepsy (SUDEP) may be improved, helping to optimize prevention and intervention. We set out to assess the frequency and demographic and clinical characteristics of SUDEP cases in a sudden death cohort. All out-of-hospital deaths were investigated from March 1, 2013 to February 28, 2015 in Wake County, NC, attended by the Emergency Medical Services. Cases were screened and adjudicated by three physicians to identify sudden death cases from any cause among free-living adults, aged 18-64. In total, 399 sudden death victims were identified during this two-year period. Seizure history, demographic and clinical characteristics, and healthcare utilization patterns were assessed from death records, emergency response scene reports, and medical records. Sudden death cases with a history of seizures were summarized by an experienced chart abstractor (SC) and adjudicated by an experienced neurologist (OD). We then compared demographic and clinical characteristics and healthcare utilization patterns of neurologist-identified SUDEP cases to other sudden death victims in our population-based registry of sudden death from any cause. SUDEP accounted for 5.3% of sudden deaths. However, seizures or complications of seizures were only considered the primary cause of death on death certificates in 1.5% of sudden deaths. SUDEP cases were more likely to have a history of alcohol abuse. Mental health disorders and a low level of medication compliance and healthcare utilization were common among SUDEP victims. SUDEP accounts for approximately 5.3% of sudden deaths from any cause in individuals aged between 18 and 64. Death certificates underestimate the burden of sudden death in epilepsy, attributing only 1.5% of sudden deaths to seizures or complications of seizures. Accurate documentation of epileptic disorders on death certificates is essential for the surveillance of SUDEP. Further, interventions that promote better use of medical services and patient engagement with healthy living practices may reduce sudden deaths in epilepsy.
