Discharge Navigator

All-in-one clinical processing suite that equips agents to structure unstructured medical notes, audit hospital discharge compliance, translate technical care plans into plain-language patient guides.

Comment

Inspiration

  • Dense Clinical Jargon: Discharge summaries overwhelm patients with technical terminology, increasing the risk of medication errors and avoidable readmissions.
  • Administrative Burden: Manually auditing every departing patient's file against mandatory hospital discharge protocols is highly tedious and error-prone.

What it does

  • Extraction & Compliance Auditing: Securely structures raw clinical notes into clean JSON and cross-references the care plan against hospital rules to automatically flag missing protocols.
  • Empathetic Literacy Translation: Translates complex jargon into an easy-to-understand, 8th-grade reading level daily routine while explicitly isolating emergency "Red Flag" warnings.

How we built it

  • Custom MCP Backend: Built an independent, asynchronous Python MCP server (FastMCP) featuring deterministic, hardcoded tools to completely eliminate LLM hallucinations.
  • State Machine Orchestration: Configured a central Orchestrator Agent with authoritative default trigger behaviors to lock in sequential tool execution (Extract $\rightarrow$ Audit $\rightarrow$ Translate) without manual user intervention.
  • Optimized Containerization: Packaged the backend in a lightweight python:3.12-slim Docker container to ensure seamless wheel installations, unbuffered logging, and stable cloud deployment.

Challenges we ran into

  • FHIR API Restrictions: Overcame 403 Forbidden blocks on restricted database endpoints by pivoting our Python tools to extract structured data directly from the active workspace text.
  • Agent Handoff Loops: Solved early LLM handoff loops and tool hallucinations by baking strict negative constraints ("Role Denial") and automatic triggers directly into the master prompt.

Accomplishments that we're proud of

  • Frictionless Automation: Achieved an incredibly smooth, one-click user experience where simply asking to "Process this patient" autonomously drives the entire multi-tool workflow.
  • Hybrid Logic Precision: Successfully paired deterministic Python guardrails (for rigorous parsing and auditing) with generative AI reasoning (for empathetic translation).

What we learned

  • MCP Integration: Mastered building and securely exposing local tools via Server-Sent Events (SSE) to external cloud-agent platforms.
  • Advanced Prompt Control: Learned how to enforce strict sequential state machines and override default LLM conversational hesitations using negative constraints.

What's next for Discharge Navigator

  • Live EHR Webhooks: Integrating bi-directional webhooks for automated, real-time synchronization with electronic health record systems at the exact moment of discharge.
  • Dynamic Rulebooks & Localization: Scaling the compliance auditor to ingest dynamic, department-specific JSON rulebooks and adding native multilingual translation for patient guides.
