Building a Bidirectional Epic Integration for Hospital-at-Home (HL7 v2 + FHIR R4)

A complete, working bidirectional Epic integration layer for a Hospital-at-Home care platform — built on HL7 v2 and FHIR R4, deployed on a live stack, and tested end to end. This walkthrough covers why Epic integration is the real bottleneck for HaH platforms, the thin-transport / fat-engine architecture (Mirth Connect + Python/FastAPI), live inbound and outbound data-flow demos, the reliability and HIPAA/SOC-2 posture, and the clinical use cases the layer unlocks — remote monitoring, care coordination, analytics, AI workflows, and multi-EHR expansion. ⏱ Chapters 00:00 Intro & about the presenter 01:10 Why Hospital-at-Home depends on Epic 04:30 What I built — overview & the FHIR landscape 07:00 Architecture (Mirth + Python) 08:30 Live demos — data flowing both ways 12:30 Reliability, security & data design 14:30 Outcomes & validation 16:30 Applications & use cases 20:15 Path to go-live & wrap-up 🔗 Links GitHub repository: https://github.com/mohcinemadkour/epi...
