Burden of disease in patients with a history of status epilepticus and their caregivers

Abstract

Objective: Status epilepticus (SE) is a life-threatening neurological emergency with the potential for wide-ranging impact on patients and caregivers. In this study, the burden of disease in patients with a history of SE and their caregivers was assessed.

Methods: Adult patients as well as caregivers of children, adolescents, and adults who had experienced ≥1 SE event in the past 24 months completed an online survey. Functional, social, emotional, and economic burden in patients and caregivers was assessed. Burden was measured through concept-targeted questionnaires, including the US Centers for Disease Control and Prevention (CDC) Health-Related Quality of Life 4 (HRQoL-4) and the Work Productivity and Activity Impairment (WPAI) instruments.

Results: The 198 respondents comprised 49 adult patients, 51 caregivers of children, 47 caregivers of adolescents, and 51 caregivers of adults. Most patients (93.9%) were diagnosed with epilepsy. Patients' daily activities were highly affected, and many respondents reported a substantial long-term physical and mental impact on patients. The mean CDC HRQoL-4 score for unhealthy days per month ranged from 11.1 for caregivers of adults to 16.9 for caregivers of children. WPAI scores demonstrated a substantial impact on the ability of adult patients and all caregivers to work. Among respondents, caregivers of children reported the highest absenteeism from work (20%) and the lowest employment rate (33%). Proportions of caregivers reporting that their daily social life was impacted at least 'some of the time' ranged from 80% to 92%, with nearly half (47%) of caregivers of children responding that their social life was impacted 'all the time'.

Conclusions: Status epilepticus episodes place a high burden on patients and caregivers. Notably, the burden appeared high across a variety of domains. This study highlights that the burden of disease is pronounced and wide-reaching and goes beyond the immediate physical and medical impact of an SE episode.
