Patient-reported outcomes in adults after status epilepticus: A systematic review.

Impairments after status epilepticus have generally been assessed by physicians, using generic scales. Patient-reported outcomes (PROs) directly reflect each patient's experience and are therefore recommended to improve patient-centered care. The objective of this systematic review was to compile the available information on patient-reported outcomes of adults after status epilepticus. We used Medical Subject Headings terms to search PubMed, Embase, and the Cochrane Library from database inception to February 2023. We excluded reviews, case reports, abstract-only reports, editorials, and publications in languages other than English or French. Studies reporting PROs in adults after SE were eligible. Bias in included studies was assessed using the Newcastle-Ottawa Scale (NOS). Given the heterogeneity in assessment tools and outcomes, most of the results are presented separately for each included study. Only three studies met our criteria. All used an observational cohort design. Two were retrospective and one prospective. Of the 141 patients (76 males and 65 females, mean age 43-63 years), 105 (74.4 %) had a history of epilepsy before status epilepticus. The studies used four epilepsy-specific and five generic tools to assess five patient-reported outcomes: quality of life (n = 141), mental health (depression, n = 81, or anxiety, n = 49), physical health including fatigue (n = 130), return to work (n = 49), and side effects of antiepileptic drugs (n = 81). A single study (n = 81) was of good methodological quality. Health-related quality of life (HRQOL) and mental health were the most extensively studied outcomes, and both were impaired. HRQOL scores ranged from 41.7 ± 11.5 to 48.3 ± 24.5. The prevalence of depression and anxiety varied from 30 % to 36 %, and from 22 % to 62 %, respectively. However, data were not collected before the status epilepticus episode, and the possible impact of this last on the outcomes cannot therefore be assessed. Information on PROs of adults after status epilepticus is extremely scant. Patient-reported outcomes should be collected more widely in adults after status epilepticus.
