Summary

MedRLM is a Recursive Multimodal Health Intelligence framework designed for long-context clinical reasoning, sensor-guided screening, and community-to-tertiary referral optimization. It addresses limitations of current medical large language models and retrieval-augmented generation systems that struggle with heterogeneous, longitudinal patient data distributed across electronic health records, medical images, sensor streams, and guidelines. Instead of compressing information into a single prompt, MedRLM treats the patient case as an external clinical environment, recursively inspecting, decomposing, retrieving, verifying, and synthesizing data. The framework coordinates specialized agents for various modalities and introduces a Clinical Evidence Graph Memory to connect patient observations with retrieved evidence and referral criteria. It also features sensor-guided recursive triggering and uncertainty-gated refinement, aiming to provide auditable, multimodal, and workflow-aware clinical decision support. A real-data evaluation design using public and credentialed clinical datasets like MIMIC-IV and PTB-XL is outlined.

Key takeaway

For AI Scientists developing clinical decision support systems, simply expanding LLM context windows or using basic RAG is insufficient for real-world, longitudinal patient data. You should adopt a recursive, agent-based framework like MedRLM that treats patient information as an external environment. This approach, integrating multimodal data, evidence graphs, and sensor-guided triggers, will improve traceability, reduce hallucinations, and enable auditable, risk-aware referral optimization, moving beyond static question answering to workflow-aware solutions.

Key insights

MedRLM recursively processes heterogeneous patient data as an external clinical environment for auditable, workflow-aware decision support.

Principles

• Clinical reasoning benefits from recursive, multimodal evidence inspection.
• Uncertainty-gated refinement enhances safety in AI clinical support.
• Sensor data can trigger deeper, context-aware diagnostic pathways.

Method

MedRLM recursively decomposes clinical queries into modality-specific subtasks, invokes specialized agents, builds a Clinical Evidence Graph Memory, and synthesizes risk-aware referral recommendations, guided by sensor triggers and uncertainty.

In practice

• Deploy specialized agents for clinical text, EHR, imaging, and sensors.
• Build an evidence graph to link patient data with guidelines.
• Use sensor-guided triggers to initiate deeper diagnostic reasoning.
