Epic EHR Replaced Cerner
From Beckers Hospital Review Feb 2020
Epic and Cerner dominate the EHR marketplace, with both companies combined accounting for more than 50 percent of the acute care hospital market share, according to KLAS.
In 2018, Epic had 28 percent of the market while Cerner had 26 percent. It appears though that Epic has increased its percentage since then notwithstanding some large contracts wins by Cerner which include the DoD and the Veterans Adminstration. The VA is currently specing out its next generation patient check-in and it appears to be hybrid between VistA and the new Cerner. The VA leadership has stumbled some recently so whether they are on schedule or not remains to be seen.
Becker has a list of 11 hospitals which switched from Cerner to Epic in the last 5 years including AdventHealth.
