[HealthChain](https://dotimplement.github.io/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](https://jenniferjiangkells.com/), an honorary researcher at the [University College London Hospitals](https://www.uclhospitals.brc.nihr.ac.uk/) (UCLH) NHS Foundation Trust, highlighting its roots in a premier healthcare institution. <!--truncate--> ### 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. ### Get Started We encourage you to explore the project and see what's possible. - HealthChain: https://dotimplement.github.io/HealthChain/ - Clinical Coding Demo: https://dotimplement.github.io/HealthChain/cookbook/clinical_coding/
