WorldVistA is an open source implementation of the Veteran Administration's Electronic Health Record system intended for use in health care facilities outside the VA. ==Background== The US Veterans Administration developed the most widely distributed electronic health record used in the US, the Veterans Health Information Systems and Technology Architecture (VistA). In an effort to make the system widely available to institutions outside the Veterans Administration health system, the software code was placed in the Public Domain under the Freedom of Information Act. The foundation for the WorldVistA EHR was formed to extend and collaboratively improve the VistA electronic health record and health information system for use outside of its original setting. It was originally developed as part of the VistA-Office project, a collaborative effort funded by the United States Centers for Medicare and Medicaid Services (CMS), an agency of the US Department of Health and Human Services (DHHS). WorldVistA EHR VOE/ 1.0 is based on and compatible with the U.S. Department of Veterans Affairs (VA) world-renowned EHR, Veterans Health Information Systems and Technology Architecture (VistA). A fully open-source (GPL v2 licensed) project, WorldVistA has also developed software modules (such as pediatrics, obstetrics, and other functions) not used in the veterans' healthcare setting. In 2006, WorldVistA EHR VOE/ 1.0 was the only open source EHR that met Certification Commission for Healthcare Information Technology (CCHITSM) ambulatory electronic health record (EHR) criteria, and in January 2008, it was released with full CCHITSM EHR. As a free product developed in co-operation with the US government, WorldVistA is not marketed in a similar fashion to commercial EHRs. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「WorldVistA」の詳細全文を読む スポンサード リンク
