New Hyde Park, N.Y.-based Northwell Health has moved its original 21 hospitals and more than 800 ambulatory care locations onto Epic with the full activation of the third wave of its EHR rollout.
The Wave 3 go-live took place the weekend of Nov. 7-8 and completes the program’s initial scope, Douglas Thompson, vice president and chief application officer at Northwell, said in a Nov. 10 LinkedIn post. The effort began four years ago, he said.
Mr. Thompson said the work “strengthens Northwell’s ability to be more agile” and that the health system is moving on to its next group of sites.
Elena Sethi, assistant vice president of enterprise digital services at Northwell, said in a separate LinkedIn post that Wave 3 brought all of the system’s legacy hospitals onto a single EHR. Ms. Sethi put the ambulatory count at more than 900 sites.
Northwell’s first major go-live came in November 2025, covering hospitals and ambulatory sites in its Western region, including Westchester, Manhattan and Staten Island. Its second wave, spanning nine hospitals in the Central region on Long Island, was billed as one of Epic’s largest implementations to date and touched roughly 42,000 users.
Northwell announced the shift from Allscripts to Epic in March 2023. The roughly $1.2 billion project aims to unify more than 30 legacy EHRs at the 28-hospital system, with a handful of hospitals still to convert. That footprint grew with the system’s merger last year with Danbury, Conn.-based Nuvance Health.
Northwell aims to complete its full Epic transition by 2030.
