Abstract: INTRODUCTION: The electroencephalogram (EEG) is a useful tool in the diagnosis of pathologies such as non-convulsive status epilepticus (NCSE) or brain death (BD), cardiac arrest (CA), and status epilepticus (SE) treatment monitoring. In addition, it provides irreplaceable information depending on the time it is performed, as is the case with the diagnosis of epilepsy after a first epileptic seizure (ES) or to differentiate these from non-epileptic paroxysmal events (NEPE). Its usefulness is maintained outside the usual working day, but it is not available in many centers. SUBJECTS AND METHODS: Retrospective observational study based on the clinical history of 86 patients who underwent an on-call EEG (ocEEG) at our hospital during 2020. RESULTS: One hundred two records requested by Intensive Care (41.1%), Neurology (37.3%), Pediatrics (17.6%) or other services (4%) were made. Suspected NCSE represented 56.7%, followed by treatment monitoring in EE (21.6%). The ME accounted for only 6.9% of the total. The ocEEG avoided potential iatrogenesis in a 56.3% of cases with therapeutic implications, allowed to treat 27.58% of patients who would have remained without treatment until the conventional EEG. An increase in the level of care was required in only 22,2% of all cases. The ocEEG was anticipated a mean of 31.6 hours to the next conventional EEG that would have been available. CONCLUSIONS: The availability of ocEEG is beneficial in terms of diagnosis, therapy, and hospital management, advancing decision-making and avoiding iatrogenesis. Its availability should become widespread.
