Achieving EHR and PMS Synchronization via HL7 FHIR: A Dental Network Case Study
Healthcare Interoperability at Scale | EHR–PMS Sync - Crunch Crunch
Crunch Crunch implemented standards-based synchronization between Electronic Health Records (EHR) and Practice Management Systems (PMS) using HL7 FHIR and AWS.
Summary
A fast-growing US dental network faced challenges integrating its Electronic Health Record (EHR) and Practice Management System (PMS). This project successfully implemented real-time, secure data synchronization between both systems using the HL7 FHIR standard.
Key Players
Details
The client was a rapidly growing US-based dental practice network operating two critical clinical systems: a primary EHR and a separate PMS. They needed to ensure consistent data across both platforms, allowing clinicians to view and update patient information (such as medications and procedures) in real time. The solution utilized HL7 FHIR standards for interoperability. Technically, it involved deploying an on-premises middleware layer (FHIR transformation/orchestration) to facilitate bidirectional data exchange with the master EHR. A cloud backend was established on AWS using API Gateway and Lambda, incorporating Cognito for robust authentication and authorization. Furthermore, identity federation was implemented using common Identity Providers (IdPs) like Okta or Azure AD, enabling Single Sign-On (SSO) across both on-premises applications and cloud services. This standards-based approach minimized the need for custom integrations, ensuring compliance with strict regulations like HIPAA/GDPR. The result provided standardized data exchange, enhanced operational reliability through centralized monitoring, and built an extensible integration layer that simplifies onboarding new clinics or vendors.
