About this paper

Heejoon Koo

The authors introduce LONGINUS, a training-free system for predicting diagnosis codes at a patient’s next visit. It combines retrieval from visit-aware history with a trajectory memory, then adjudicates disagreements without revealing which view proposed the diagnosis. Across two MIMIC datasets and four LLM backbones, it achieves best transition-specific F1 in 22 of 24 settings, but does not lead uniformly on aggregate metrics.
