Regional Hospital Network Unifies 18 EHRs Through FHIR Interoperability

About the Client

The client is a regional healthcare network operating multiple hospitals and outpatient facilities across several locations. Clinical data was fragmented across 18 different EHR systems, making it difficult for providers to access complete patient records and coordinate care effectively. The organization required a scalable interoperability platform to unify healthcare data, improve care continuity, and support future digital health initiatives. To achieve this transformation, the healthcare network partnered with Zymr.

Key Outcomes

Unified Data Across 18 EHR Systems
Processed 2.4+ Million Patient Encounters

Business Challenges

The healthcare network relied on multiple disconnected EHR platforms acquired over several years. Patient records were distributed across 18 separate systems, making it difficult for clinicians to access complete and up-to-date medical histories.

The lack of interoperability created duplicate patient records, inconsistent clinical information, and delayed care coordination between hospitals, specialty clinics, and outpatient facilities. Manual data reconciliation increased administrative effort and introduced avoidable errors.

ADT (Admission, Discharge, and Transfer) messaging inconsistencies frequently disrupted clinical workflows, impacting patient transfers and delaying critical care decisions. Existing integration methods also lacked scalability to support growing data volumes and evolving interoperability requirements.

The organization needed a modern, standards-based interoperability platform capable of securely exchanging healthcare data in real time while providing a unified patient view across the entire network.

Business Impacts / Key Results Achieved

Zymr implemented a FHIR-based interoperability platform that connected disparate EHR systems into a unified healthcare ecosystem. The solution improved clinical data accessibility, reduced integration errors, and established a scalable digital foundation for future healthcare innovation.
