Regional Hospital Network Builds a Longitudinal Patient Record Across 18 EHRs

About the Client

The client is a regional hospital network operating 18 independent EHR systems across multiple hospitals, outpatient clinics, and specialty care centers. Disconnected clinical data limited care coordination, population health initiatives, and value-based care performance. The organization required a unified interoperability platform to create a complete longitudinal patient record. To achieve this transformation, the network partnered with Zymr.

Key Outcomes

Unified Longitudinal Patient Records Across 18 EHR Systems
Integrated More Than 2.4 Million Patient Encounters

Business Challenges

The hospital network operated multiple EHR platforms that functioned independently, making it difficult to establish a single, comprehensive patient record. Clinicians often lacked access to complete patient histories, resulting in fragmented care and duplicated clinical efforts.

Population health initiatives were limited by inconsistent data formats and disconnected clinical systems. Care teams struggled to identify high-risk patients, monitor quality measures, and coordinate care across hospitals and outpatient facilities.

The absence of standardized interoperability also delayed reporting for value-based care programs and limited actionable insights for clinical leadership. The organization required a scalable interoperability platform capable of unifying clinical data while supporting analytics, care coordination, and regulatory reporting.
