Objective: This study was undertaken to characterize changes in health care utilization and mortality for people with epilepsy (PWE) during the COVID‐19 pandemic. Methods: We performed a retrospective study using linked, individual‐level, population‐scale anonymized health data from the Secure Anonymised Information Linkage databank. We identified PWE living in Wales during the study "pandemic period" (January 1, 2020–June 30, 2021) and during a "prepandemic" period (January 1, 2016–December 31, 2019). We compared prepandemic health care utilization, status epilepticus, and mortality rates with corresponding pandemic rates for PWE and people without epilepsy (PWOE). We performed subgroup analyses on children (<18 years old), older people (>65 years old), those with intellectual disability, and those living in the most deprived areas. We used Poisson models to calculate adjusted rate ratios (RRs). Results: We identified 27 279 PWE who had significantly higher rates of hospital (50.3 visits/1000 patient months), emergency department (55.7), and outpatient attendance (172.4) when compared to PWOE (corresponding figures: 25.7, 25.2, and 87.0) in the prepandemic period. Hospital and epilepsy‐related hospital admissions, and emergency department and outpatient attendances all reduced significantly for PWE (and all subgroups) during the pandemic period. RRs [95% confidence intervals (CIs)] for pandemic versus prepandemic periods were.70 [.69–.72],.77 [.73–.81],.78 [.77–.79], and.80 [.79–.81]. The corresponding rates also reduced for PWOE. New epilepsy diagnosis rates decreased during the pandemic compared with the prepandemic period (2.3/100 000/month cf. 3.1/100 000/month, RR =.73, 95% CI =.68–.78). Both all‐cause deaths and deaths with epilepsy recorded on the death certificate increased for PWE during the pandemic (RR = 1.07, 95% CI =.997–1.145 and RR = 2.44, 95% CI = 2.12–2.81). When removing COVID deaths, RRs were.88 (95% CI =.81–.95) and 1.29 (95% CI = 1.08–1.53). Status epilepticus rates did not change significantly during the pandemic (RR =.95, 95% CI =.78–1.15). Significance: All‐cause non‐COVID deaths did not increase but non‐COVID deaths associated with epilepsy did increase for PWE during the COVID‐19 pandemic. The longer term effects of the decrease in new epilepsy diagnoses and health care utilization and increase in deaths associated with epilepsy need further research. [ABSTRACT FROM AUTHOR]

Objective: People with epilepsy (PWE) may be at an increased risk of severe COVID‐19. It is important to characterize this risk to inform PWE and for future health and care planning. We assessed whether PWE were at higher risk of being hospitalized with, or dying from, COVID‐19. Methods: We performed a retrospective cohort study using linked, population‐scale, anonymized electronic health records from the SAIL (Secure Anonymised Information Linkage) databank. This includes hospital admission and demographic data for the complete Welsh population (3.1 million) and primary care records for 86% of the population. We identified 27 279 PWE living in Wales during the study period (March 1, 2020 to June 30, 2021). Controls were identified using exact 5:1 matching (sex, age, and socioeconomic status). We defined COVID‐19 deaths as having International Classification of Diseases, 10th Revision (ICD‐10) codes for COVID‐19 on death certificates or occurring within 28 days of a positive SARS‐CoV‐2 polymerase chain reaction (PCR) test. COVID‐19 hospitalizations were defined as having a COVID‐19 ICD‐10 code for the reason for admission or occurring within 28 days of a positive SARS‐CoV‐2 PCR test. We recorded COVID‐19 vaccinations and comorbidities known to increase the risk of COVID‐19 hospitalization and death. We used Cox proportional hazard models to calculate hazard ratios. Results: There were 158 (.58%) COVID‐19 deaths and 933 (3.4%) COVID‐19 hospitalizations in PWE, and 370 (.27%) deaths and 1871 (1.4%) hospitalizations in controls. Hazard ratios for COVID‐19 death and hospitalization in PWE compared to controls were 2.15 (95% confidence interval [CI] = 1.78–2.59) and 2.15 (95% CI = 1.94–2.37), respectively. Adjusted hazard ratios (adjusted for comorbidities) for death and hospitalization were 1.32 (95% CI = 1.08–1.62) and 1.60 (95% CI = 1.44–1.78). Significance: PWE are at increased risk of being hospitalized with, and dying from, COVID‐19 when compared to age‐, sex‐, and deprivation‐matched controls, even when adjusting for comorbidities. This may have implications for prioritizing future COVID‐19 treatments and vaccinations for PWE. [ABSTRACT FROM AUTHOR]
