VISTA Architect: A graph database-oriented health AI system demonstrated in multidisciplinary tumor boards

Stanford Medicine researchers unveiled VISTA Architect, a graph database-powered AI system that integrates large language models with electronic health records to achieve 96.4% accuracy in clinical data extraction for tumor board preparation. The architecture precomputes patient histories into organized knowledge graphs, reducing processing time and latency compared to traditional RAG approaches while maintaining full data provenance.

Adoption and Use of LLMs at an Academic Medical Center

Researchers at an academic medical center developed ChatEHR, an LLM system integrated into electronic health records that enables both automated clinical tasks and interactive use across patient timelines. Over 1.5 years, the platform achieved adoption by 1,075 users conducting 23,000 sessions, generating an estimated $6M in first-year savings while maintaining vendor-agnostic governance.

Clinical Term Extraction using Open-Source Small Language Models

Researchers evaluated 26 open-source small language models for extracting clinical terms related to amyotrophic lateral sclerosis (ALS) from unstructured patient notes, finding that hybrid approaches combining rule-based methods with machine learning outperform either approach alone. The study demonstrates that modest-sized language models can handle specialized medical information extraction tasks without task-specific training, though traditional regex-based systems remain competitive for this application.
