- 4Rare diseases are still difficult for AI to handle
- 5Building trust with patients requires extensive explainability features
Details
The article discusses the development of Helios Med, a multi-agent AI system designed to assist doctors in the diagnostic process. The system has 383 specialized agents covering various medical domains, with a triage agent, specialist agents, a 'Grand Rounds' feature for complex cases, and a report generator. The key lessons learned include the importance of multi-model consensus, which improves accuracy over single-model systems, and the need for structured output in the form of SOAP notes, which is crucial for doctor adoption. The team also faced challenges with FHIR integration, which was necessary but difficult, and struggled with rare diseases, where AI still has limitations. Building trust with patients required extensive explainability features. The article also covers the technical stack, including a custom multi-agent orchestration framework, FHIR R4 integration, and end-to-end encryption for patient data.
