Utilization of Epilepsy Monitoring Unit by General Neurologists

Background Epilepsy monitoring unit (EMU) is a growing service that allows physicians to evaluate, diagnose, and manage epilepsy in a safe and cost-effective way. However, observations have indicated that the EMU is being underutilized by general neurology practice, possibly due to the lack of access and specific criteria known to all neurologists. There is limited data as of yet to support these observations. This study reviewed the rate of referral to the EMU from outpatient general neurology clinics at our institution. Methods In this retrospective study, records of 350 patients, 18 years or older with a diagnosis or diagnostic workup of epilepsy, managed by neurologists who did not specialize in epilepsy, were reviewed. We classified patients into three groups: ineligible for EMU referral, eligible and referred to EMU, and eligible but not referred to EMU based on six criteria namely characterization, classification, localization, determination of seizure frequency, medication adjustment, and differentiation between seizures and medication side effects. Results Our results demonstrated that 36.7% of patients who did meet the criteria were not referred to EMU. The most common criteria for patient referral in both groups, referred and not referred, was the characterization of seizures as epileptic or functional. Conclusion Our results show that EMU is underutilized by our general neurology clinics. Providing more information and increased awareness about criteria for long-term monitoring in EMU can improve the utility of this valuable tool and would be beneficial to patient care.
