Researchers introduce EHR-Complex, a large-scale benchmark with 52K tasks for evaluating AI clinical agents on real-world electronic health record analysis. Testing reveals significant limitations, with top models achieving only 62.3% accuracy and exposure of three dominant failure modes: SQL logic errors, medical code lookup failures, and semantic misunderstandings.
Researchers introduce PhysAssistBench, a new evaluation framework for testing large language models in real-world clinical settings where physicians, patients, and electronic health records interact simultaneously. The benchmark reveals that current leading LLMs struggle with coordinating medical knowledge, patient communication, and precise system interactions together, exposing a critical gap between isolated capability improvements and practical clinical assistance.
Researchers propose a lightweight adaptation method to apply tabular foundation models to clinical survival analysis, demonstrating that pretrained representations combined with survival-aware objectives outperform traditional approaches. Testing on MIMIC-IV and eICU datasets shows 1.4-1.7% improvements over strong baselines like DeepSurv in predicting patient mortality and time-to-event outcomes.
Researchers have developed MED-COPILOT, an AI-powered clinical decision-support system that combines GraphRAG retrieval with similar patient case analysis to assist healthcare professionals. The system uses structured knowledge graphs from WHO and NICE guidelines along with a 36,000-case patient database to outperform standard AI models in clinical reasoning accuracy.
