WorldVistA EHR is an open source electronic health record (EHR) based on the highly acclaimed VistA system of the United States Department of Veterans Affairs (VA). The foundation for WorldVistA EHR was developed as part of the VistA-Office project, a collaborative effort funded by the Centers for Medicare & Medicaid Services (CMS), an agency of the Department of Health and Human Services (DHHS). The overall goal of the VistA-Office EHR (VOE) project was to encourage the broader adoption and effective use of EHRs among physicians by making a robust, flexible EHR solution alternative available. After completion of the VOE project in March 2007, WorldVistA made additional enhancements and submitted WorldVistA EHR for certification by theCertification Commission for Healthcare Information Technology(CCHIT).
WorldVistA EHR, Version VOE/1.0 achieved full CCHIT EHR. WorldVistA EHR 2.0 is Meaningful Use (Certified HIT Product) certified by the U.S. Office of the National Coordinator for Health IT (ONC).
