Researchers have introduced LongMedBench, a new benchmark designed to evaluate the long-horizon clinical decision-making capabilities of medical AI agents. Unlike previous evaluations that focused on short-context question-answering, LongMedBench utilizes real-world electronic health record (EHR) data from MIMIC-IV, integrating patient histories, notes, and medical events over extended periods. The benchmark includes three evaluation suites: fact-based QA, temporal reasoning, and long-horizon decision-making, aiming to assess how agents leverage historical patient information. Initial experiments indicate that while current LLMs can utilize explicit timestamps, they struggle with implicit time inference, and while retrieval-augmented generation (RAG) and memory systems improve information retrieval, decision-making performance remains context-dependent.
