We're excited to share a new open-source project from the community that addresses a common developer challenge: integrating with legacy healthcare systems. HealthChain, an open-source Python framework, makes it easier to connect AI/ML pipelines to healthcare systems.

This project is a perfect example of how the open-source community is tackling real-world problems. It was created by Jennifer Jiang-Kells, an honorary researcher at the University College London Hospitals (UCLH) NHS Foundation Trust, highlighting its roots in a premier healthcare institution.

Connecting Epic to Medplum​

One of HealthChain's most useful examples is a "Note Reader" service that integrates Epic NoteReader with Medplum. This demo shows how to process clinical notes, extract data like billing codes, and map them to the FHIR format. This addresses a key pain point for developers who need to modernize data workflows without replacing their existing Epic infrastructure.

By connecting Epic NoteReader to a modern FHIR server like Medplum, this project demonstrates a practical, open-source solution for developers. It's a powerful tool for bridging the gap between legacy CDA systems and modern healthcare platforms.

We encourage you to explore the project and see what's possible.
