Surveying neurologist perspectives and knowledge of epilepsy surgery to identify barriers to surgery referral

Abstract

Abstract Objective Epilepsy surgery is an effective means of treating medically refractory epilepsy (MRE), but it remains underused. We aimed to analyze the perspectives and knowledge of referring neurologists in the New York metropolitan area, who serve a large epilepsy population. Methods We adapted a previous Canadian survey by Roberts et al. (2015), adding questions regarding demographic descriptors, insurance coverage, training and practice details, and perceived social barriers for patients. We surveyed neurologists directly affiliated with Montefiore Medical Center and those referring to Montefiore's Comprehensive Epilepsy Center. Participants had 10 weeks to fill out an online Qualtrics survey with weekly reminders. Results Of 117 neurologists contacted, 51 eligible neurologists completed the survey (63.8% Montefiore, 35.0% referring group). A high proportion of the results were from epilepsy‐trained individuals (41.2%) and neurologists who graduated residency ≤19 years ago (80.4%). 80.4% of respondents felt that epilepsy surgery is safe, but only 56.9% would refer a patient for surgical workup after two failed trials of anti‐seizure medications. Epileptologists and providers with a larger volume of epilepsy patients and electroencephalogram readings had better knowledge of the epilepsy surgery workup guidelines. When asked to rank social barriers to patients receiving surgery, participants were most concerned about lack of social support, financial insecurity, and a patient's dual role as a caregiver. Significance Our study suggests continued reluctance of neurologists regarding epilepsy surgery, and deficiencies in the knowledge and adherence to the recommended guidelines. In the context of prior studies, these results showed improved understanding of the definition of MRE (80.4%) and an increased likelihood to refer eligible patients as early as possible (78.4%) in line with current consensus recommendations. The finding that epilepsy‐trained and more epilepsy/electroencephalogram‐facing neurologists showed better understanding of the guidelines suggests that increased education efforts should be targeted at non‐epileptologists. Plain Language Summary Our study asked New York City doctors about their approach to epilepsy surgery. Many do not consider it as early as they could in treatment plans. The doctors with extra epilepsy training were better at knowing when to consider surgery.
