Vital Trace: Protocol-Constrained Patient-State Reasoning for Longitudinal Clinical Trajectories

ArXi:2602.12833v2 Announce Type: replace-cross Longitudinal clinical reasoning over electronic health records requires tracking evolving physiological measurements, laboratory results, and interventions across extended patient trajectories. Existing LLM-based clinical reasoning systems often rely on repeatedly serializing patient histories or exchanging unconstrained textual agent messages, leading to context drift, unstable reasoning, and growing inference cost over long horizons.
