Case Study: Regional Hospital Network unifies 18 EMRs and improves healthcare analytics with Zymr's FHIR Lakehouse

Regional Hospital Network unifies 18 EMRs with Zymr and cuts ADT message errors by 68%

The customer, a regional hospital network, faced significant challenges due to fragmented clinical data across 18 legacy EMR systems. This lack of interoperability limited care coordination and analytics, creating a heavy reliance on manual data validation. To overcome this, the organization partnered with Zymr to build a unified, scalable data platform.

Zymr designed and implemented a modern healthcare data platform using a medallion lakehouse architecture to standardize and operationalize the clinical data. The solution transformed data into FHIR R4 format, implemented automated validation, and ensured HIPAA-compliant security. As a result, Zymr helped the client achieve a 68% reduction in ADT message errors and create a unified patient record covering 2.4 million annual encounters.
