Case Study: Agent-driven Diagnostic Support
A recent implementation in a major hospital demonstrated the effectiveness of LLM-based agents in enhancing diagnostic accuracy. By integrating with the hospital's Electronic Health Records (EHR) system and leveraging medical knowledge graphs, the agent was able to process patient data, identify potential diagnoses, and suggest relevant tests. In one complex case involving rare disease, the agent's insights led to a correct diagnosis three weeks faster than traditional methods, significantly improving patient outcomes.
