The client managed 18 separate EHR systems across 12 hospitals and hundreds of clinics. Historical data was fragmented, incomplete, and inconsistent, preventing full EHR consolidation. Past migration attempts had stalled due to data quality concerns and clinician distrust of imported records.
Hart deployed HealthMigrate™ to unify and validate more than 20 years of patient data as part of a large-scale healthcare data integration initiative.
Initially, Hart utilized the universal adapter to extract each EHR database and aggregate them into a single data lake. From there, Hart deployed the intelligence layer of Hart Platform to map normalized data to the new Epic EHR system-of-record schema and apply organizational data-retention policies.
All records were validated at multiple steps in the extraction, transformation, and load (ETL) process, ensuring confidence and long-term healthcare interoperability success.
98% validated data accuracy across all migrated records 3.2 million records consolidated into the new Epic EHR 14 legacy systems decommissioned within six months $3.2 million in annual IT savings from decommissioning, driving strong healthcare data modernization ROI Clinician confidence in migrated data rose from 62% to 96% within 60 days of go-live

Behavioral health and acute care systems operated separately, creating incomplete patient records and compliance gaps — a common barrier to healthcare interoperability success.

The payer’s data team needed to unify clinical, claims, and pharmacy data for performance reporting and risk adjustment — a critical requirement for value-based care.
