TL;DR AI
2 min readKey summary
Researchers introduced COTCAgent, a hierarchical clinical agent for longitudinal EHR reasoning.
It combines temporal statistics, weighted symptom-trend-disease scoring, and bounded evidence completion to reduce hallucinated clinical trends.
On a self-built dataset and HealthBench, it outperformed prior medical agents and general LLMs.
The work could strengthen diagnostic support for time-series patient records and improve reliability in healthcare LLMs.
