Social determinants do not affect access to specialized epilepsy care in veterans

Utilization of epilepsy care among Women Veterans: A population-based study

OBJECTIVE

Higher healthcare utilization in epilepsy correlates with better clinical and quality of life outcomes. Women Veterans with epilepsy (WVE) have unique characteristics that may affect access and utilization of care. This study investigates epilepsy care in WVE, with respect to utilization of outpatient, inpatient, and emergency room care.

METHODS

Data were collected from 58,525 Veterans with epilepsy using the Veterans Health Administration (VHA) Corporate Data Warehouse administrative data. Overall, 8.5% of the sample were women (n = 4983). Neurology visits, comprehensive epilepsy care, neuroimaging, ASM prescription and hospital and emergency care were analyzed, and comparisons were made with men Veterans with epilepsy to identify gender differences.

RESULTS

Compared to men, a greater proportion of WVE utilized services including neurology (73.8% vs. 62.0%), comprehensive epilepsy care (16.1% vs. 11.7%), epilepsy monitoring unit evaluation (EMU; 6.1% vs. 2.9%), neuroimaging (CT: 39.1% vs. 36.6%; MRI: 43.7% vs. 32.5%), and electroencephalograms: (EEG: 36.5% vs. 29.1%). WVE also evidenced higher percentages of seizure-related emergency room care usage vs. men (15.2 vs. 12.6) and hospitalizations (12.3 vs. 10.0) and were prescribed a greater number of ASMs (average:2.3 vs. 1.9). Valproate was prescribed to 17.6% of WVE, despite potential teratogenic concerns.

SIGNIFICANCE

WVE have greater utilization of epilepsy care within the VHA system compared to men, which could lead to better epilepsy management and quality of life. However, higher rates of emergency care, hospitalizations, and concurrent ASMs among WVE highlight the clinical complexity and raise concern for potentially comorbid conditions including psychogenic non-epileptic seizures.

Association Between Standardized Mortality Ratio and Utilization of Care in US Veterans With Drug-Resistant Epilepsy Compared With All US Veterans and the US General Population

Importance

Drug-resistant epilepsy (DRE) is thought to be associated with increased mortality, but larger population-based studies are lacking. Additionally, the benefit of effective management in DRE lacks evidence.

Objective

To examine the association of utilization of care with mortality in US veterans with DRE.

Design, Setting, and Participants

Observational cohort study conducted between October 1, 2013, and March 31, 2020. Mortality statistics in US veterans with DRE were compared to the US general population and all veterans within the Veterans Health Administration. Epilepsy was defined as use of 1 or more antiseizure medications (ASMs) for 30 days or longer with a seizure diagnosis or 1 inpatient or 2 outpatient encounters with an epilepsy diagnosis. DRE was defined as the use of 2 or more ASMs. Among 9.6 million US veterans, 164 435 (1.7%) had epilepsy, of whom 55 571 (33.8%) had DRE. Epilepsy and DRE were administratively identified based on criteria noted in design. Identified participants were included for analysis.

Exposures

Veterans with DRE.

Main Outcomes and Measures

Standardized mortality ratio (SMR).

Results

Among US veterans with DRE, the mean (SD) age was 58.3 (15.4) years, and 49 430 individuals (88.9%) were male. Of ethnicity data gathered, 3170 individuals (5.7%) were Hispanic or Latino, 50 599 (91.1%) were not Hispanic or Latino, 842 (1.5%) declined to answer, and 960 (1.7%) were recorded as unknown. Of race data gathered, 516 individuals (0.9%) were American Indian or Alaskan Native, 270 (0.5%) were Asian, 11 316 (20.4%) were Black or African American, 587 (1.1%) were of multiple races, 453 (0.8%) were Native Hawaiian or Pacific Islander, 39 543 (71.2%) were White, 1697 (3.1%) declined to answer, and 1189 (2.1%) were recorded as unknown. SMR was 1.50 (95% CI, 1.47-1.53) compared with the US general population and 1.56 (95% CI, 1.53-1.59) compared with all veterans. Utilization rates were 81.1% (n = 45 057) for neurology clinic evaluation, 66.4% (n = 36 905) for magnetic resonance imaging (MRI), and 49.6% (n = 27 546) for electroencephalography (EEG) testing. Only 8350 individuals (15.0%) had comprehensive epilepsy evaluations and 3357 (6.0%) had epilepsy monitoring. Multivariable analysis revealed an association between lower mortality and neurology clinic evaluation, EEG, MRI, epilepsy monitoring, and the use of more than 2 ASMs after adjusting for age and comorbidities.

Conclusions and Relevance

Mortality rates were significantly higher in US veterans with DRE compared to the general population. Better utilization of comprehensive epilepsy care, diagnostic services, and medications were each associated with reduced mortality. These findings indicate that appropriate management of DRE is critical in this population.

Socioeconomic disparities in epilepsy care

PURPOSE OF REVIEW

Epilepsy is a common, chronic neurologic disease with continued disparities in care. The COVID-19 pandemic and recent social movements have drawn greater attention to social determinants of health and our progress (or lack thereof) toward delivering more equitable care.

RECENT FINDINGS

Recent studies continue to document racial and economic disparities in diagnosis, treatment, and overall care of epilepsy and associated conditions. Notably, an increasing number of studies are attempting to design healthcare pathways and other interventions to improve access and equity in epilepsy care.

SUMMARY

The present literature highlights the importance of identifying and addressing the particular needs of vulnerable persons with epilepsy. Practitioners and researchers should continue to develop interventions aimed at improving care for all patients and, crucially, measure the impact of their changes to ensure that any interventions are truly advancing health equity.

Characterizing women veterans receiving seizure care in the veterans affairs healthcare system

OBJECTIVE

The number and proportion of women served by the Veterans Health Administration (VHA) is rapidly expanding, necessitating better characterization of factors unique to this population. While nascent literature has begun to better characterize women within the broader seizure population, women Veterans remain an understudied sample. To expand our clinical understanding of women with seizures, we assessed demographic and clinical characteristics, as well as psychiatric/military histories in women receiving care from an Epilepsy Center of Excellence within the VA Healthcare System.

METHODS

The sample included 90 women with psychogenic nonepileptic seizures (PNES) and 28 women with epileptic seizures (ES) as the final diagnosis after epilepsy monitoring at a large VA medical center between 2010 and 2020. Retrospective chart review gathered demographics, including age, marital status, and work status; clinical characteristics, including history of traumatic brain injury (TBI) or migraines, gynecological history, and use of anti-seizure medications (ASM); psychiatric information, including trauma history, psychiatric diagnoses, and treatment; and military history related to service or service connection. Group differences were assessed between women with PNES and ES.

RESULTS

The ES group was significantly older than the PNES group (47.8 v. 41.9 years, p = 0.02) and had a non-significantly longer diagnosis duration (12.3 vs. 8.6 years, p = 0.17). Clinically, the PNES group had a significantly higher rate of migraines (76.7% v. 57.1%, p = 0.04) and hysterectomy (40% v. 17.9%, p = 0.03). Many psychiatric factors differentiated the two groups, with significantly higher rates of psychotropic medication use (86.7% v. 60.7%, p = 0.002), psychiatric hospitalization (42.2% v. 21.4%, p = 0.047), and suicide attempts (42.2% v. 14.3%, p = 0.005), alongside trends toward higher rates of military sexual trauma (47.8% vs. 28.6%, p = 0.07) and childhood sexual trauma (37.8% vs. 17.9%, p = 0.05) among those with PNES.

SIGNIFICANCE

This is the largest study to date characterizing women veterans with seizures seeking comprehensive seizure care and provides an update to previously published information on Veteran samples with seizures. Several characteristics differ between women Veterans with PNES and ES, spanning demographic, clinical, and psychiatric factors. Understanding the unique profile of women Veterans with epilepsy seeking care through the VA system is a crucial step in providing optimal care, including making informed diagnosis and providing appropriate treatment.
