complete OpenVistA stack consists of:
GNU / Linux
combination of the GNU tools and the Linux kernel, which together
provide a robust, scalable OSFS operating system.
implementation of the Standard M
programming system (M = MUMPS = Massachusetts General Hospital Utility
Multi-Programming System). VistA is written in Standard M. GT.M is an
implementation of M from Sanchez
Computer Associates, Inc.. GT.M on the x86 GNU / Linux platform has
been released as OSFS and can be downloaded from Source Forge.
Health Information Systems and Technology Architecture, a Healthcare
Information System (HIS). VistA is widely believed to be the largest
integrated HIS in the world. It was originally developed and maintained
by the U.S.
Department of Veterans Affairs (VA), based on the systems software
architecture and implementation methodology developed by the U.S.
Public Health Service jointly with the National Bureau of Standards. It
is designed to provide a high-quality medical care environment for the
country's military veterans. VistA has a proven track record of
supporting a large variety of clinical settings and medical delivery
VistA is in production today at hundreds of healthcare facilities
across the country from small outpatient clinics to large medical
centers. The software is currently used by the Indian Health Service
and a number of other healthcare organizations around the world.
standards-compliant, object-relational, database management and
interoperability system from ESI
Technology Corporation. ESI has already worked with the VA and
Department of Defense (DoD) to demonstrate how well EsiObjects works
with VistA, so at the February/March VistA Community meeting in Green
Belt, Maryland we'll formally add EsiObjects to the OpenVistA stack.
WorldVistA recommends the
use of OSFS and open standards, beyond the HIS stack. In particular, we
use OpenOffice as our integrated
office suite to develop all documentation, spreadsheets, presentations,
etc. We suggest the use of Mozilla
on GNU Linux to view web
We are deeply grateful to Source Forge for providing us with
our place in cyberspace for this web site.
