http://www.vistasoftware.org What is VistA?
VistA is a trusted, proven, & economical electronic health record system.
VistA is an (open source) enterprise-wide, fully integrated, fully
functional information system built around an electronic health record.
It is easily customizable and can be configured to fit any type of
healthcare organization, from clinics and medical practices to nursing
homes and large hospitals. VistA has been named one of the best
healthcare information systems in the nation by the Institute of
Developed by the Department of Veterans Affairs, the VistA healthcare
information system supports the hospitals and clinics serving veterans
throughout the US. VistA has been deployed in thousands of healthcare
facilities, both domestic and international.
Because VistA is available in the public domain, there are no license
fees to use the software.
'Few hospitals go paperless using free VA software'
By Lisa Wangsness, The Boston Globe, May 4, 2009
WASHINGTON - In a country where just 1.5 percent of US hospitals have
fully computerized records, one of the poorest and least technologically
advanced states has created a paperless records system for its state-run
hospitals and nursing homes.
West Virginia did it by using an electronic medical records system built
by the Veterans Administration with taxpayer dollars, saving millions in
software licensing fees charged by commercial software vendors.
The VA software, known as VistA, is open-source software - its code is
freely available to the public and is constantly being improved by users,
and it includes important features, such as a bar-coding system to track
drug dispensations, to help improve patient safety.
But very few US hospitals have taken advantage of it. Wealthier hospitals
have opted to buy more expensive, custom systems from private vendors,
while smaller and more rural hospitals often stick with paper records.
"I would think there would be a tremendous opportunity for using this as
a platform, particularly for smaller hospitals that have a real challenge
in coming up with the money for electronic medical records," said Dr.
William Weeks, an associate professor at Dartmouth Institute for Health
Policy and Clinical Practice, and a psychiatrist in Vermont.
Phillip Longman, a fellow at the New America Foundation and author
of "Best Care Anywhere," a book about the Veterans Administration's
quality-of-care revolution, said VistA is an unrecognized national
"It's really insane that we have a fully developed health information
technology system that is bought and paid for and free to anybody who
wants it and used widely around the world by other governments running
their healthcare systems . . . and yet we don't have any take-up in the
US, or not much to speak of," he said.
Some policy makers are working to change that. Senator Jay Rockefeller, a
West Virginia Democrat who chairs the Finance Committee's health
subcommittee, is introducing legislation that would promote the
widespread adoption of VistA and other open-source systems among
hospitals that serve the poor. He also successfully pushed to include
provisions in the stimulus bill to make VistA more accessible.
Massachusetts' well-known hospitals have been pioneers in health-
information technology - the doctors and technicians across the country
who collaborated to build VistA piece by piece in the 1970s and 1980s
used programming language first developed by Massachusetts General
Hospital, Longman said.
VistA was designed mainly for clinical use, not for billing - the VA gets
most of its money from the government, not from insurance reimbursements.
But billing components can be added on, specialists say.
John Halamka, the chief information officer for Beth Israel, which has a
custom electronic records system, is a fan of open source, and called
VistA "one piece of the puzzle," but cautioned that it was designed for
large institutions with a single payer, and would not work well in, say,
small doctors' practices with a large array of payers.
"We should disseminate VistA where it's a good fit," he said, but finding
a single system to fit the needs of every clinician "is just not
Michael Siegel, a professor at MIT's Sloan School of Management, said he
thought small rural hospitals in western Massachusetts "could very much
benefit from an open-source system, but they're not."
Technology experts cite a number of reasons why: The software itself is
free, but as Siegel noted it still costs millions to install and
maintain, so money remains a barrier.
There is also another problem - installing and running VistA requires
skilled technology workers, a resource lacking in many hospitals,
particularly smaller and more rural institutions.
But because so few hospitals have adopted the technology, only a few
consulting firms - like Medsphere, which brought VistA to West Virginia -
provide that expertise.
"I think people are sitting back and waiting a little until they see
enough momentum for it," Siegel said.
The system also looks clunkier than commercial software, and its
capacities are less honed for medical specialties that the Veterans
Administration has not traditionally offered or focused on, such as
But companies like Medsphere say VistA is highly adaptable and those
capabilities can be built.
Edmund Billings, Medsphere's chief medical officer, said it can be
difficult to persuade hospital executives to buy into a system that does
not have a large sales force to promote it. The private vendors, he
added, have deployed a significant lobbying force in Washington, and the
Bush administration's pro-private sector leanings put the focus on
developing standards to try to get different brands of commercial
software to communicate - not on promoting a government-sponsored
"The business software alliance lobbies against any open-source
provisions," he said. "And that's a hard thing to beat when they have
Rockefeller said he hopes to change that by fully underwriting the
roughly $10 billion cost of installing and maintaining open-source
electronic records systems in all of the country's safety-net hospitals,
removing a barrier that he fears could lead to a deepening divide between
health information haves and have-nots.
Even with generous subsidies from the Obama administration's $19 billion
health technology investment in the stimulus bill, many hospitals still
can't afford an electronic records system.
"This legislation does not replace commercial software; instead, it
complements the private industry in this field by making health
information technology a realistic option for all providers," Rockefeller
said in a statement.
Rockefeller's legislation would also create a federal public utility
board to coordinate upgrades to a national open-source system and build a
standard child-specific electronic health record for the Medicaid program.
Rick Peters, an emergency room doctor and technology consultant from San
Diego, said ideally the federal government would fund an open-source
project to create a more sophisticated and user-friendly VistA that could
serve as a kind of national canvas for experimentation and innovation.
"VistA is fantastic and should be used, but the energy should be on
updating and rearchitecting VistA over time," he said.
