Assessing the personal impact of epilepsy in a population-based cohort of Veterans.
Epilepsy impacts patient lives in multidimensional ways. Although previous work has investigated epilepsy impact on health status, little is known about the overall quantified impact of epilepsy in Veterans. Our goal was to describe the impact of epilepsy on Veterans' lives using the Personal Impact of Epilepsy Scale (PIES) and determine the patient and clinical characteristics most strongly correlated with epilepsy impact. We described cohort characteristics and developed regression models to determine which characteristics were most strongly associated with PIES subscale (seizure, medication, comorbidity) scores and quality of life (QOL). ⋯ Findings were similar to a prior study of generic health outcomes in younger and older VWE using the 36-Item Short Form Survey (SF-36). Seizure frequency was consistently associated with negative impact of epilepsy in all age groups. While dementia and other diagnosed health conditions also contributed to epilepsy impact, older VWE had significantly lower PIES scores even after controlling for physical conditions and dementia. Lower (better) scores for comorbidity and medication scales in older VWE may be due to fewer diagnosed psychiatric comorbidities and psychiatric medication that have similar cognitive impact as AEDs, and which may also interact with AEDs. Implementation of patient self-management programs to improve seizure control may reduce epilepsy impact for Veterans and reduce Veterans Affairs (VA) healthcare utilization. The PIES may also be useful to measure outcomes of self-management interventions.
