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 and creating significant risk for a large-scale EHR migration case study.
Past migration attempts had stalled due to data quality concerns and clinician distrust of imported records.
Hart deployed HealthMigrate™ to unify and validate over 20 years of patient data as part of a large-scale healthcare data integration results initiative.
Initially, Hart utilized the universal adapter to extract each EHR database and aggregate it into a single data lake. From there, Hart deployed the intelligence layer of the 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 costs, 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.
