Contribution & Novelties
The presentation contributes a novel approach to ED capacity management by integrating machine learning predictions with discrete event simulation to evaluate proactive versus reactive full capacity protocols. The use of a holistic decision support system and the comparison of multiple ML algorithms (including TST+) on real hospital data provides practical insights. The simulation results highlight that proactive deployment may not significantly reduce average turnaround time but can smooth the process by reducing peaks and time above thresholds.
