The Veterans Health Information Systems and Technology Architecture (VISTA) is a health information system deployed across all veteran care sites in the United States. VISTA provides clinical, administrative, and financial functions for all of the 1700+ hospitals and clinics of the Veterans Health Administration VISTA consists of 180 clinical, financial, and administrative applications integrated within a single transactional database (see figure 1).
The Veterans Health Administration (VHA) is the largest integrated national healthcare delivery system in the United States, providing care for nearly 9 million veterans by 180,000 medical professionals.VISTA received the Computerworld Smithsonian Award for best use of Information Technology in Medicine, and continues to the present day to receive the highest physician satisfaction scores in national Electronic Health Record (EHR) surveys. In 2014 and again in 2016 national surveys of over 15,000 physician users of EHRs rated VISTA with the highest overall satisfaction rating in the U.S. Over 65% of all physicians trained in the U.S. rotate through the VHA and use VISTA, making VISTA the most familiar EHR in the U.S.In May, 2018, the VA awarded a contract to Cerner Corp to replace VistA with the commercial off-the-shelf EHR, Cerner Millenium. Pilot implementations took place in the fall of 2020, and by November, 24 million veteran health records had been migrated to the new platform. The projected completion for migration of all VA sites is 2028.
