What is VistA?

VistA is a public domain electronic health record programmed by federal employees working for the US Department of Veterans Affairs (previously the Veterans Administration) over the past several decades. For more info, see this page.

What is RPMS?

RPMS is a public domain electronic health record that is used by the Indian Health Service (IHS). Prior to the 1980s it used a different architecture from VistA, but since the 80's it has shared a large amount of its architecture with VistA. For more info, see this page.

What is Vistapedia?

Vistapedia is a wiki for several varieties of the public domain versions of VistA and RPMS. Information about the integrated VistA installer called Astronaut is also contained within these pages.

This wiki covers installation, configuration, and usage of these VistA derivatives. It also serves as an introduction to the VistA Documentation Library for everyone outside the VA. In addition, current events, development advances, and other news about the flavors of VistA are posted here.

This wiki runs the same software as Wikipedia.
