Abstract

Objective: Health-related quality of life (HRQOL) improves after resective epilepsy surgery, but data are limited to short follow-up in mostly retrospective reports, with minimal consideration of other potential factors that might influence HRQOL. Methods: In a prospective multicenter study, 396 patients underwent resective epilepsy surgery. They completed the Quality of Life in Epilepsy Inventory-89 (QOLIE-89) before surgery, within 6 months, and at approximately yearly intervals after surgery. Seizure outcome was ascertained by phone calls every 3 months, and dates of postoperative seizures were chronicled. Overall HRQOL as measured by the QOLIE-89 was evaluated with respect to seizure outcome using logistic regression. Results: QOLIE-89 scores increased significantly at the first postoperative measurement (within 6 months after surgery) in the cohort overall; subsequent changes over time were sensitive to seizure-free and aura-free status. After adjusting for baseline scores, the corresponding postsurgical QOLIE-89 overall, and four dimension scores, increased as a function of square root of time seizure-free, and independently as a function of square root of time aura free, leveling by 2 years of stable seizure (aura) status. HRQOL was not independently related to duration of epilepsy, duration of intractable epilepsy, or continuation of medications. Interpretation: HRQOL improves early after surgery, regardless of seizure outcome. Subsequent changes parallel length of time seizure free or aura free, stabilize after 2 years, and are unrelated to duration of epilepsy, duration of intractable epilepsy, or continued medication use.
