Enterprise Clinical Copilot：基于 LangGraph + Gemini 的再入院风险评估全栈应用

Enterprise Clinical Copilot

Enterprise Clinical Copilot (ECC) is a full-stack AI application. The application is designed to help healthcare professional assess unplanned readmission risk at discharge time for patients who have been admitted to the hospital for at least 24 hrs.

The application is built thoughtfully using trusted AI Architecture patterns. While the application itself is a prototype, the software is architected to run at enterprise scale, currently deployed on GCP.

The user interface to the application is built using django on my personal website. You can view the companion repo , to look at the source code for the web app.

The system is separated into deployable services and offline ML workflows:

The Django application is maintained in the companion repository. It is the public boundary for authentication, demo-cohort authorization, quota, and presentation. The agent service owns language-model orchestration. The MCP service owns reusable prediction and retrieval tools.
