Cerner spent decades shaping how hospitals manage patient records. Founded in 1979 in Kansas City, the company grew from a small consulting outfit into one of the two dominant EHR vendors in the United States. Its Millennium platform powers medical records, clinical workflows, revenue cycle management, and population health analytics for thousands of facilities.
The system handles everything from physician order entry and medication tracking to lab results and billing. Cerner’s HealtheIntent data platform aggregates clinical and claims data across organizations, giving health systems a broader view of patient populations. The company also built CommunityWorks, a shared-instance EHR for smaller hospitals that can’t afford full on-premise deployments.
Oracle completed its $28.3 billion acquisition of Cerner in mid-2022, making it one of the largest healthcare IT deals in history. Under Oracle’s ownership, the focus shifted toward cloud migration and AI-powered clinical tools. Before the acquisition, Cerner had roughly 27,000 employees and its software touched over 260 million patient records globally. The rebrand to Oracle Health hasn’t slowed deployments — new contracts with the VA and Department of Defense keep the platform central to U.S. healthcare infrastructure.
