Warren made the remarks in his keynote address at the 2nd annual summit of the Open Source Electronic Health Record Alliance (OSEHRA):
I know I have already talked a lot about VistA, but I cannot in good [conscience] pass up an opportunity to brag about how it plays a role in providing the quality care Veterans receive at VA. VistA at VA supports the care for over six million veterans, with 75 million outpatient visits and 680,000 inpatient admissions at more than 1,500 sites of care, including: 152 hospitals, 965 outpatient clinics, 133 community living centers, and 293 Vet Centers.
These facilities are run by over 244,000 employees including more than 20,000 physicians and 53,000 nurses and have affiliations with more than 1,200 educational institutions where more than 100,000 health care students receive clinical training from VA each year.Warren spoke about VistA Evolution, the VA's current effort to use "open source" software innovations to improve the scheduling and other aspects of the care provided to veterans by the VA. (The VA recently awarded $3 million in prizes in a contest for medical appointment scheduling applications.) An April 2014 presentation by the VA spells out the VistA Evolution concept in great detail, including this timetable for its development and implementation:
The presentation borrowed from the popular comic strip Dilbert to make the point about the challenges faced in upgrading the information systems:
Warren addressed the VA's ambitious plans for VistA evolution at the OSEHRA summit:
VistA Evolution will improve patient-centered care and provide Veterans access to a comprehensive medical profile that supports the transition of care between VA and DOD treatment facilities.
One of VA’s top priorities is increasing access to care for our nation’s Veterans. VistA is a prime example of how Open Source is helping to develop and deliver an evolved version to meet that priority. The fundamental purpose of VA’s Open Source initiative was to accelerate the evolution of VistA. While VistA provides an integrated view of a patient and VA clinicians love it, we were not keeping up with the demands of our customers, the clinician..
The ultimate goal of this Open Source effort is to standardize 133 production VistA instances in support of the VA’s medical centers and clinics and is expected to be complete at all VA sites by the end of 2015.The VA's previous effort to upgrade its systems ran for nine years, from 2000 to 2009, and cost $127 million, but in the end did not deliver and was scrapped.
While the inspector general's report this week does not appear to be critical of VistA itself, it noted that "[d]uring our review at Phoenix HCS we determined that certain audit controls within Veterans Health Information Systems and Technology Architecture (VistA) were not enabled. This limited VHA and the OIG’s ability to determine whether any malicious manipulation of the VistA data occurred." The VA since turned VistA's audit controls.
