Distributions of VistA

Distributions of VistA

One of the main advantages of Open Source software is its malleable nature; it can readily be customized to fit into unique clinical environments and workflows, or extended to integrate with other software and devices.

The myriad of options can be confusing at first, it often makes sense to start with a baseline version of VistA from which you may either build your own solution, or elect to work with an existing distribution. To get you started in VistA, OSEHRA offers a basic community distribution based on the VA FOIA VistA that has been enhanced with OSEHRA VistA as well as some initial guidance and tools to get you up and running. These resources are meant to help get you acclimated to VistA, from there, the choice is yours.

Embracing and helping make sense of the distributions across the community is something OSEHRA takes an active role in. We help newcomers understand the various distributions available, in order to guide them to work with the one that best fits their needs. Below is a high level overview of some of the major distributions available today.
