A new benchmark, ClinTraceBench, has been developed to evaluate the ability of clinical large language models to reason over longitudinal patient data. The benchmark, derived from MIMIC-IV dialogues, includes nine tasks and a rigorous validation process. Researchers assessed eight different history representation strategies, including retrieval, structured timelines, and agentic memory systems, across four LLM backbones: DeepSeek-V3, GPT-4o mini, Haiku~4.5, and Sonnet~4.6. Key findings indicate that compressed strategies suffer from an "aggregation tax" on multi-visit trends, and agentic memory systems still struggle to recover injected information, suggesting limitations in current methods for preserving longitudinal signals in clinical reasoning.
