130 Continuous EEG monitoring in australia: s first year audit of practice 2018–2019 of a combined hospital epilepsy program in melbourne. (29th July 2019) - Laing, Joshua
Abstract : Introduction: Continuous EEG (cEEG) monitoring is essential for the optimal diagnosis and management of non-convulsive seizures. We audited the use of cEEG across two major metropolitan hospitals in Melbourne, Australia as part of a new combined epilepsy program. There are no reported case series of cEEG in Australia. Methods: Data was collected retrospectively from consecutive patients who underwent cEEG monitoring as part of their acute inpatient care between Jan 2018 to Dec 2018 at the Alfred and Royal Melbourne Hospitals. All inpatient EEG studies over 1 hr were included. Elective cases from the epilepsy monitoring unit were excluded. Demographic and clinical information regarding their admission was collected. Descriptive statistics, and comparative analysis was performed. Results: There were 94 patients identified that underwent cEEG. 50% were male and 50% female, with an average age of 51.3 yrs. 45% were performed in the ICU, and 55% on the acute medical ward. The average duration of recording per patient was 86.2 hrs or 3.6 days. Of 89 of 94 available cEEG reports, seizures were seen in 55%, the majority being non-convulsive. Interictal discharges were seen in 60%. 19% (13/67 of available records) were dead at the time of the audit. Conclusion: Non-convulsive seizures and non-convulsive status epilepticus is common and widely underrecognized without cEEG. We present 94 cases as part of our newly expanding cEEG program across two major Australian hospitals over a one year period, 55% with seizures which were predominantly non-convulsive. A prospective database will be designed for further quality improvement and future research.
