Comorbidities in Hispanic/Latino Veterans with epilepsy.

BACKGROUND

Hispanic/Latino people with epilepsy may be at a differential risk of medical and psychiatric comorbidities given genetic, environmental, sociocultural, and quality of care factors. In people with epilepsy, comorbidities are especially crucial to investigate given the well-known impact on quality of life and risk of adverse outcomes. Yet, Hispanic/Latino Veterans with Epilepsy (HL-VWE) remain an understudied population. The present nationwide population study sought to investigate medical and psychiatric comorbidities in this group.

METHODS

Data from the Veterans Health Administration (VHA) Corporate Data Warehouse administrative data were used to identify 56,556 VWE (5.7 % HL-VWE) using a one-year cross-sectional analysis of ICD codes. Elixhauser Comorbidity Index scores and psychiatric diagnoses were calculated based on ICD-9/ICD-10-CM diagnoses using a lookback period. Comparisons were made between HL-VWE and non-HL-VWE using chi-squared and student t-tests. Regression analyses were then performed to examine group differences while accounting for age.

RESULTS

HL-VWE had higher probability of being diagnosed with several psychiatric conditions when accounting for age, including depression (OR 1.21, 95 % CI 1.13-1.31) and schizophrenia (OR 1.56, 95 % CI 1.31-1.84). There were no significant differences in medical comorbidities between the HL-VWE and non-HL-VWE groups.

CONCLUSIONS

We present results from the largest known study of HL people with epilepsy examining their psychiatric and medical comorbidities and one of the first to specifically study HL-VWE. Compared to non-HL-VWE, the Hispanic/Latino group had comparable medical comorbidity, but higher rates of multiple psychiatric conditions. Results indicate a need for increased screening and interventions in this population to reduce psychiatric disease burden.
