Hospitals and health systems are consolidating electronic health record platforms as they work to unify patient information and reduce the number of systems operating across their organizations.
The projects vary in scope, with some health systems replacing dozens of legacy EHRs and Kaiser Permanente combining multiple instances of the same platform. All seven systems below are consolidating onto Epic.
Here are seven health systems that have completed or are pursuing major EHR consolidations, based on Becker’s reporting:
1. Northwell Health (New Hyde Park, N.Y.): More than 30 EHRs
Northwell Health is consolidating more than 30 core EHRs across its 28 hospitals and hundreds of ambulatory sites into a single Epic platform as part of a $1.2 billion investment.
The health system’s second major implementation wave went live May 30, bringing approximately 42,000 users across nine hospitals onto Epic. As of August, about 70,000 users had transitioned to the platform. Another implementation wave is scheduled for November, with a handful of hospitals remaining after that.
2. Vandalia Health (Charleston, W.Va.): 27 EHRs
Vandalia Health plans to consolidate 27 EHRs onto Epic across its 16 hospitals and more than 220 ambulatory sites following several years of expansion.
The health system is targeting a fall 2028 go-live, with all 16 hospitals and more than 220 clinics moving to Epic on the same day. CIO Daniel Stross told Becker’s the organization began weighing its options as its Oracle Health contract approached expiration, and that it anticipates recovering its Epic investment within seven years. In early October, Mr. Stross said Vandalia expected to sign its Epic contract that month.
3. CommonSpirit Health (Chicago): 19 EHRs
CommonSpirit Health has reduced its EHR portfolio from 19 systems to nine over a 24-month period as it works toward a single Epic instance.
During an Oct. 2 investor webcast, CFO Michael Browning said about 67% of the health system’s facilities were on Epic. CommonSpirit is targeting completion of its consolidation by the end of fiscal 2030, two years earlier than previously projected, after deciding to insource its revenue cycle. The health system will pause its Epic rollout during its Workday ERP go-live, scheduled for July 1, 2027.
4. Kaleida Health (Buffalo, N.Y.): 13 EHRs
Kaleida Health retired 13 legacy EHRs when it launched Epic across its acute and ambulatory sites May 30.
The five-hospital system previously used platforms including Athenahealth, Medent, Meditech and Oracle Health. Unlike health systems pursuing phased implementations, Kaleida completed its transition in a single go-live following approximately 18 months of preparation.
5. Kaiser Permanente (Oakland, Calif.): 12 Epic instances
Kaiser Permanente consolidated 12 Epic EHR instances into two in early 2025, one serving Northern California and the other Southern California.
The project involved migrating approximately 40 million patient records. Unlike the other projects on this list, Kaiser consolidated multiple instances of the same EHR rather than replacing different EHR products. The consolidation covered California only. Kaiser now operates eight clinical EHR instances, one for each of its eight markets, according to Neil Cowles, chief information and technology officer.
6. UPMC (Pittsburgh): 9 EHRs
UPMC is consolidating nine EHRs into a single Epic platform across its network of more than 40 hospitals and 800 physicians’ offices and outpatient centers.
The health system completed its second major implementation wave in early October, transitioning 15 hospitals and hundreds of ambulatory practices to Epic. UPMC announced in 2023 that it planned to complete the consolidation by mid-2026. The health system previously used Oracle Health for inpatient care and Epic for ambulatory services as its core platforms.
7. Intermountain Health (Salt Lake City): 8 EHRs
Intermountain Health completed its consolidation of eight EHR systems into a single Epic platform Sept. 6, 2025, through a systemwide implementation spanning 33 hospitals.
The health system opted to launch Epic across its facilities simultaneously rather than use a phased rollout. By December 2025, the transition had stabilized, and Intermountain’s revenue cycle performance had surpassed Epic’s median benchmarks after a slower start. CFO Clay Ashdown said the single-day approach allowed the system to identify and resolve problems more efficiently.
