Postoperative Delirium Prediction

The DELPHI-EEG model leverages a sophisticated deep learning architecture to process raw multi-channel intraoperative EEG signals. This framework allows for the extraction of complex spatiotemporal features and modeling of time-dependent patterns, crucial for robust POD prediction.

53.04% F1-score Reduction when Alpha Band Power is Removed

The model identified that attenuated alpha power, along with increased delta and theta power, is a key predictor of POD. Ablation studies confirm alpha band's critical role, highlighting the model's ability to discern neurophysiological correlates of delirium beyond traditional markers like burst suppression. This aligns with neurophysiological understanding of thalamo-cortical connectivity impairments in POD.
