A Randomized Controlled Trial and Pilot of Scout: an LLM-Based EHR Search and Synthesis Platform

Collection of recent ML/IR papers with several security- and safety-relevant findings. Key items: Scout—an LLM-based EHR search/synthesis platform demonstrated time/workload reductions in an RCT and larger pilot (200+ users, ~6.6k interactions) but depends on citation linking and human validation because automated LLM-judges both miss and mislabel chart-supported claims (privacy and patient-safety risk if deployed without oversight). Chunk-as-a-Service (CaaS) and UCOSA introduce budgeted retrieval selection for RAG pipelines to reduce cost; the change in which chunks are returned raises data‑s
