Measuring the effects of pre-test probability on out-patient first EEG investigation in children – a guide to evidence-based EEG triage in a pandemic

Optimum management of children with suspected seizure disorders involves combination of a specialist child-neurology opinion and recording of an EEG1–3. Interictal epileptiform abnormalities (IEAs) occur in 30-64% of first-time EEGs in children with first unprovoked seizure or epilepsy presentations4–6 and are associated with higher rates of seizure recurrence7. Beyond estimation of recurrence risk, EEG can sometimes help to identify specific epilepsy syndromes, which can be particularly informative for the management and prognosis of some children1.
