Powering healthcare for over 30 years.
VistA stands for "Veterans Health Information Systems and Technology Architecture." Originally created in the 1970's, VistA is the Electronic Health Record actively developed and currently used by the Department of Veterans Affairs (VA), the largest healthcare system in the United States with over 300,000 employees and 5,000 IT professionals. VistA is a comprehensive system for managing both large and small healthcare entities, providing functions ranging from prescription refills to employee timekeeping.
VistA is used and loved by hospitals and clinics around the world. In fact, a 2011 survey conducted by the American Academy of Family Physicians found VistA CPRS (Primary VistA User Interface) in the top of 10 rankings of user satsifaction, and #1 in several categories.
While having a massive domestic presence (Over half the doctors in the US have trained with VA), VistA is seeing rapid growth in international adoption; it has been installed in places such as Mexico, Germany, India, and Jordan.
Open Source = Rapid Innovation.
VistA is free and open-source. OSEHRA VistA is licensed under the Apache 2.0 License. Open-source enables adopters to improve code and share enhancements fluidly and freely. For providers, this typically means lower cost, higher interoperability, and better integration into clinical workflows.
In 2011, VA funded an effort to create a 'custodial agent' for VistA, with the aim of collaboratively developing future VistA enhancements with the rest of the world. By creating this organization, now known as OSEHRA, releasing VistA to it and redefining their their development practices around open-source VA has made a strong commitment to sharing the future of VistA with citizens, veterans, and the rest of the world.
This site is the home of OSEHRA VistA, providing resources for any community member who wishes to learn, share, and help shape the future of this technology.
What is OSEHRA VistA?
OSEHRA VistA is a community supported, open-source Electronic Health Record capable of being adapted and implemented by the healthcare industry. It maintains bi-directional compatibility with the Department of Veterans Affairs implementation of VistA, as well as the community at large, so enhancements may be shared and integrated universally.
OSEHRA VistA’s growth and evolution are entirely managed by the community. By design, the product is composed of a core platform and a collection of interacting components in order to best support the many community implementations.
What is OSEHRA VistA's relationship to the other distributions of VistA?
One of the many advantages of open source code is that it may be taken and modified to meet particular needs. Clinics may elect to use RPMS, a distribution used by Indian Health Service geared toward ambulatory care. Vendors in the community have modified and extended VistA to better fulfill their customer needs, and offer the software as supported products. If you are considering VistA and have unique and un-met requirements, it may make sense to create your own distribution based on what is available in OSEHRA VistA. An index of the current distributions produced by community members can be found here.
While many of these distributions pre-date the creation of OSEHRA VistA, this codebase is meant to be a common version of VistA wherein enhancements may be shared amongst these distributions. Moving ahead, contributions from these distributions are being integrated into OSEHRA VistA as prioritized by the community.
How do I get started?
OSEHRA provides source code and a number of supporting resources to get you up and running on a basic OSEHRA VistA instance, to learn more click here.
Next, depending on your interest in OSEHRA VistA, you are encouraged to engage with the OSEHRA community. Developers may wish to learn more and contribute to development, while hospitals considering a production installation might engage with OSEHRA corporate members to explore how their needs may best be addressed.
