## AI overview

This technical post describes HelloBetter's implementation journey from Germany's ePA 2.6 to ePA 3.0. It covers HealthID login, ePA data export, PDF and XML document writing, and the frontend and backend integrations used to connect therapeutic data across systems. The implementation was completed pending BfArm approval.

From ePA 2.6 to 3.0: A Technical Journey in Healthcare Data Integration for Electronic Patient Records...so far Germany has a bad reputation for digitalisation, so the government's push to implement an electronic patient record ("elektronische Patientenakte" or ePA) for its citizens and residents is a step in the right direction. As an official digital health application ("digitale Gesundheitsapplikation" or "DiGA"), we are obligated to shift to the ePA 3.0 implementation. The government rollout has been plagued with technical difficulties and delays, but we're now at a point where we have completed our implementation successfully, pending BfArm approval. In this post, I want to cover the exact steps we and had to take to achieve this. I want to thank Senior Product Manager Tanja Lembcke and Senior Backend Engineer Chaythanya Sivakumar for their contributions to this piece. The Challenge: Connecting Patient Data Across Systems The electronic patient record (ePA) and HealthID integration project had a clear mission: we wanted to give our patients the ability to log into the HelloBetter platform using their HealthID (which they access through their insurance company) and export their HelloBetter data into their ePA. A successful implementation would mean that both doctors and patients can electronically access therapeutic data whenever they need it. To make this happen for the patient data at HelloBetter, we partnered with two key players: RISE for ePA system access and Azuma for HealthID system access. Our journey began in 2024 when our backend team laid the groundwork for ePA 2.6, setting up the pipeline and data export in our staging environment. We successfully implemented both PDF and XML document writing capabilities, along with the frontend and backend integrations for HealthID login. How It All Works: The Architectural SideHealthID Authentication The first piece of the puzzle is connecting to and authorising the user's HealthID. This part of the system has remai
