Outline

This paper presents an automated design framework for healthcare-specific agents based on large-scale language models (LLMs). Building on the success of automated machine learning (AutoML), we define a hierarchical and expressive agent search space to overcome the limitations of existing healthcare agent systems, which rely on static workflows. This framework conceptualizes healthcare agents as graph-based architectures composed of various functional node types and supports iterative self-improvement based on diagnostic feedback. Experimental results on a skin disease diagnosis task demonstrate that the proposed method effectively evolves workflow structures and significantly improves diagnostic accuracy over time. This is the first fully automated healthcare agent architecture design framework that provides a scalable and adaptable foundation for deploying intelligent agents in real-world clinical settings.

Takeaways, Limitations

Takeaways:
Automation of medical agent architecture design presents the potential for increased efficiency and adaptability.
Improved diagnostic accuracy and flexible response to diverse diagnostic requirements.
Providing a scalable foundation for deploying intelligent agents in real-world clinical environments.
Limitations:
The performance of the proposed framework is based on experimental results for a specific skin disease diagnosis task, and further research is needed to determine its generalizability to other medical fields.
Further research is needed on the transparency and explainability of the automated workflow design process.
Additional validation and safety evaluation are needed for practical application in clinical settings.
