Large Health System Modernizes EHR, Achieves Unified Patient View and 87% Reduction in Duplicate Records

About the Client

The client is a 500-bed large health system operating multiple legacy EHR platforms across five specialty departments, including cardiology, oncology, orthopedics, primary care, and urgent care. The lack of interoperability between these systems resulted in fragmented patient records, data silos, and clinician frustration. To address these challenges and modernize its digital infrastructure, the organization partnered with Zymr.

Key Outcomes

87% Reduction in Duplicate Patient Records
360-Degree Unified Patient View Achieved

Business Challenges

The health system operated on multiple disconnected legacy EHR systems, leading to poor interoperability and lack of a unified patient record. Clinical data was fragmented across departments, making it difficult for providers to access complete patient histories and deliver coordinated care.

The absence of integration resulted in duplicate records, data inconsistencies, and increased clinical risk. Clinicians faced inefficiencies and frustration due to the need to navigate multiple systems, impacting productivity and care quality.

Additionally, the system lacked a centralized patient identity framework, further complicating data management and interoperability across departments. The organization needed a scalable solution to unify patient data, improve interoperability, and enable seamless care coordination.
