OpenVista is a collection of free open-source health information system (HIS) applications based off of the VistA server software developed by the U.S. Department of Veterans Affairs.[2]

Product history

In 1996 the U.S. Department of Veterans Affairs introduced VistA (Veterans Health Information Systems and Technology Architecture) to better support "day-to-day operations at local Department of Veterans Affairs (VA) health care facilities."[3] By 2002 the software company Medsphere Systems Corporation decided to get involved with creating an open-source version of the VA's software, with the goal of providing a free, widely available software package to "enhance patient safety" and "to improve clinical efficiency resulting in better quality healthcare."[4]

On March 4, 2007, version 1.0 of OpenVista Server was released on SourceForge.[1] Like its predecessor, OpenVista seems to have utilized an older programming language called MUMPS. However, in 2005 work contracted out by the VA set out to test the feasibility of automatically converting the 2.1 million lines of code of VistA from MUMPS to Java. This work was put on hold in 2006 due to lack of funds; however, the project was picked up again in 2009, this time applied to OpenVista. That year the MUMPS-based code of OpenVista was converted to Java as as a "scalability demonstration" of the automated process.[5]

The last update to the software was on May 24, 2011, with the introduction of OpenVista Server 1.5 Service Pack 6.[1] It's not clear if work still continues on the project.
