[ossig] Report on NIST meeting organised with WorldVistA - standards & interoperability

[Molly Cheah]

I would like to add that the most interesting part of this history is this: 
"Like VOE, the clinical IT systems in use today at the Indian Health Service and the Defense Department were based on copies of the VA's clinical IT system. But the $1 billion development at Defense was allowed to fork so badly that records could not be readily transmitted between it and the VA. Since then, taxpayers have paid many millions of dollars to make the VA and Defense systems interoperable. Thus, the forking of the Defense system ranks as one of the bigger mistakes in healthcare IT history."

I didn't think that freedom has such a high price to pay.

>>project, and
>>the foundation eventually hired WorldVistA to help.

>>had developed a branch of VistA that runs on open-source versions of

>>certification thus far is open-source.
>>A turning point
>>With all this history and success behind them, WorldVistA members face a
>>crucial turning point in addition to certification testing.
>>On Jan. 31, the $4 million CMS contract with Iowa Foundation for Medical
>>Care, and thus the foundation's contract with WorldVistA, runs out. The

>>will

>>upgrades and bug fixes to VistA that VA programmers produce at the 
>>rate of
>>500 to 600 a year. "One of the discussions that is under way as part 
>>of the
>>CMS contract is we have to be able to stay ahead of that VistA tsunami,"
>>said Schlehuber, who holds a doctorate in neuroscience and helped develop
>>the VA's computer system from 1978 until he retired last September. 
>>"We're
>>hoping that the VA recognizes their obligation when they partnered 
>>with CMS,
>>that they're responsible for maintaining it."
>>"It should not be a high-cost process," Schlehuber said, noting that it
>>should take 15 to 20 hours of programming time a month to keep up with 
>>the
>>stream. The risk is if VOE falls behind the patch stream, the two 
>>programs
>>will "fork," or go on separate development paths, a potentially costly

>>via the
>>patch stream throughout the system. The Instituto Mexicano del Seguro 
>>Social,
>>one of Mexico's national health services, has installed a Spanish 
>>language
>>version of VistA at 56 of its hospitals and has built what programmers 
>>there
>>think are improved versions of several VistA software modules. 
>>Medsphere has
>>several hospital installations under way in the U.S. using its version of
>>VistA, yet Timson's upgrades to FileMan, created when he was employed by
>>Medsphere, were not readily accepted by the VA. Other VistA vendors, 
>>aiming
>>to leverage open-source VOE and target the 200,000-physician small-office
>>market, could boost development of the software dramatically and 
>>produce a
>>stream of improvements to the software just as steady as that now 
>>emanating
>>from the VA.
>>"There are going to be a number of users of VOE that far exceeds the 
>>number
>>of users at VA," Schlehuber said. "At some point I can see that is 
>>going to
>>develop stresses in VA."
>>WorldVistA member Brian Lord is a former VA programmer who has worked 
>>on the
>>development of VOE. Lord is president of Sequence Managers Software, 
>>which is
>>selling a subscription EMR service based on VistA that is distributed to
>>clients using the application service provider, or ASP, model.
>>WorldVistA plans to release VOE under the Free Software Foundation's 
>>General
>>Public License, and that's as it should be, according to Lord.
>>"We are dedicated to open source because we believe there is a 
>>business model
>>there," he said. "We've got a PACS (picture archiving and communication
>>system) attached to our VistA, a practice-management system that's 
>>attached,
>>and it's all open-source.
>>"This product must be released under GPL," Lord said. "It has to be

>>property. They want to ensure that anybody that wants to start working 
>>with
>>VistA has to contribute to the community. Unless they are invested in the

>>"The underlying goal for all of this is to change the way healthcare is

>>exchanged, and
>>VistA is a foundation that can make that happen," he said.
