Implementing a Digital Neurocritical Care Unit for Neonates in Brazil: A 4-Year Experience

This study aimed to describe neuromonitoring findings and short-term outcomes after the implementation of a digital health strategy comprising continuous, real-time, tele-based video-aEEG/EEG monitoring in a publicly funded NICU in Brazil.Prospective, observational cohort study conducted between July 2017 and June 2021, analyzing neuromonitoring data of high-risk newborns and correlating it with clinical and imaging outcomes.A total of 116 newborns, with a median gestational age of 37 weeks (interquartile range [IQR]: 32<sup>2/7</sup>-39<sup>2/7</sup>) and a median birth weight of 2,800 g (IQR: 1,472-3,305), were enrolled with more than 8,000 hours of monitoring. The main indication was suspected seizure (<i>n</i> = 49, 42.2%). A total of 43 (37.1%) neonates presented pathological background activity, and sleep-wake cycle (SWC) was absent in 68 (58.6%).
