Cerner

Then Cerner, Oracle Health; was founded in 1979 by Neal Patterson, Paul Gorup, and Cliff Illig, who were colleagues at Arthur Andersen. Its original name was PGI & Associates but was renamed Cerner in 1984 when it rolled out its first system, PathNet. The name "Cerner" comes from the Latin word "cernere," which means "to separate" or "to discern". The name reflects the founders' vision of using software to help healthcare organizations make informed decisions and distinguish critical information.

It went public in 1986. The company's client base grew steadily in the late 1980s, reaching 70 sites in 1987, 120 sites in 1988, 170 sites in 1989, and reaching 250 sites in 1990. Installations were primarily of PathNet systems.

During this time, the company was developing components of a Health Network Architecture (HNA), an integrated IT system designed to automate health care processes. Clients could purchase individual components or the whole system at one time. By 1994, more than 30 clients had purchased the full HNA system, while 100 clients had purchased multiple components of the system.

In 1997, the company introduced Cerner Millennium, an upgrade to its HNA system which incorporated all of the company's software offerings into one unified architecture. The introduction of Millennium contributed to significant growth for the company, with revenue increasing to $1.1 billion in 2005 from $245.1 million in 1997.

IMC Health Care, Inc. was acquired in early 2010 to continue expanding its wellness services to outside commercial employers, pharmacies, and wellness programs.

In July 2010, president Trace Devanny left the company and was succeeded by founder Neal Patterson, who also served concurrently as chairman and chief executive officer. In September 2013, Zane Burke was named president, assuming the title from Patterson.

On August 5, 2014, the company announced its intent to purchase Siemens Health Services, the health information technology business of Germany's Siemens AG, for $1.3 billion. The acquisition was completed on February 2, 2015.

That July, Leidos Partnership for Defense Health, which included Cerner, Accenture, and Leidos, was awarded a 10-year, $4.3 billion contract to overhaul and manage the electronic health records for the Department of Defense.

Products

Oracle Health's primary product is the Cerner Millennium platform, an electronic health record (EHR) system. In August 2025, the company expanded their EHR offering to include AI-powered software.

Locations

Oracle Health world headquarters campus is at 2800 Rockcreek Parkway, North Kansas City, Missouri. It acquired additional space in Kansas City, Missouri in 2005 and in 2006 it acquired another location in Kansas City. In 2013, the company announced plans to redevelop 236 acres in south Kansas City, Missouri into an office park. The site was previously occupied by Bannister Mall, which was demolished in 2009. Construction broke ground on the new campus on November 11, 2014.

In 2024, Oracle Chairman, Larry Ellison, announced that the company planned to move its global headquarters to Nashville, Tennessee.

Oracle Health has offices in about 25 countries worldwide.

Controversy

In 2001, a memo authored by CEO Patterson and sent to about 400 managers was leaked online. The memo was meant to motivate the managers to get more productivity out of employees and promised layoffs, a hiring freeze, closing of an "Associate Center," and the implementation of a punch-card system if Patterson did not see evidence of changes. Patterson's metric was the fullness of the company's Kansas City office lot at the hours of 8 a.m. and 5 p.m. Following the memo's leak, company stock price fell 22% over three days.

In 2005, Cerner and other companies paid for a report by the RAND Corporation which predicted great efficiencies from electronic health records, including savings of $81 billion a year or more, which RAND now says is overstated. This report helped drive growth in the electronic health record and billions of dollars in federal incentives to hospitals and doctors. Cerner's revenue tripled from $1 billion in 2005 to a projected $3 billion in 2013. The Congressional Budget Office criticized the study for overstating potential savings. A 2013 reassessment of the 2005 report by the RAND Corporation said that the conversion had failed to produce savings and had mixed results in efficiency and patient care.

Australia

Cerner Millennium product, including the FirstNet, SurgiNet/SurgiNet Anaesthesia and RadNet platforms, form the Integrated Electronic Medical Record (ieMR) system in the state of Queensland, Australia. The implementation of Cerner Millenium drew criticism due to it costing over A$1.45 billion taking more than 10 years to complete, and hospitals experiencing implementation issues.

In 2018, Queensland Health through its digital health solutions agency, eHealth Queensland, began a restricted tender process to purchase a Patient Administration System (PAS) solution, to replace the aging iSoft PAS first introduced in the early 1990s. The procurement process was successful with the Cerner PAS solution being chosen. In early 2019, allegations arose surrounding an undeclared relationship and conflict of interest between Richard Ashby, chief information officer of eHealth Queensland, and a Cerner employee. The allegations resulted in the resignation of Ashby, the matter being referred to the Queensland Crime and Corruption Commission for investigation, and the collapse of the PAS replacement project. The commission subsequently found insufficient evidence to prosecute Ashby for corrupt conduct.

Canada

In 2016, the emergency department of Nanaimo Regional General Hospital in Nanaimo, British Columbia began using the system. The implementation, which cost $230 million, was met with widespread criticism among staff, who called it a "huge failure" due to an increase in software errors resulting in reduced efficiency of the department. An investigation by British Columbia's Health Ministry indicated that the project was not correctly planned or implemented and that organizational dysfunction at the facility contributed to the failure.

United Kingdom

In 2014, a coroner ruled that a three-year-old heart patient died as a result of a delay to his treatment at Bristol Royal Hospital for Children. The coroner ruled that the hospital's outpatient booking system was responsible for the child not being seen or receiving treatment. The Royal United Hospital had recently installed the Cerner Millennium system. However appointments for the hospital's legacy booking system were not migrated to the new system.
