Oracle Corp. (NYSE: ORCL) has closed on its previously announced $28.3 billion acquisition of Cerner as it seeks to transform the electronic health records experience.

The software giant announced on June 7 that the majority of Cerner shares had been validly tendered. The deal closed yesterday.

Cerner is a significant provider of digital information systems used within hospitals and health systems. Oracle officials have said that they think Cerner will prove to be a massive revenue growth engine.

Oracle board chair and CTO Larry Ellison said during the company’s Q3 earnings call in March that healthcare is interesting because it’s more than just the hospitals and health providers.

“The healthcare industry is much bigger than that,” Ellison said. “There are medical device manufacturers. There are pharmaceutical companies. There are the payers, insurance companies and government agencies that are all part of this healthcare ecosystem. So we’re not just focused on providers like hospitals and clinics, but also we won a big [enterprise resource planning] deal over SAP at Johnson & Johnson. We won a big ERP deal over SAP at the medical device company, Haemonetics.”

Ellison said during a webinar today that Oracle and Cerner together have all the technology they need to transform health information management. He wants Oracle to take on the challenges of the hospital-centric health records system and create a national health records system on top of all the hospital records systems inside the United States. Electronic medical records software will automatically upload the data to the national system, with patients providing access permission as needed.

Public health officials would also have access to anonymized national health data to spot problems early.
