The Department of Veterans Affairs and the Department of Defense spent at least $1.3 billion during the last four years trying unsuccessfully to develop a single electronic health-records system between the two departments — leaving veterans’ disability claims to continue piling up in paper files across the country, a News21 investigation shows. This does not include billions of other dollars wasted during the last three decades, including $2 billion spent on a failed upgrade to the DOD’s existing electronic health-records system. For a veteran in the disability claims process, these records are critical: They include DOD service and health records needed by the VA to decide veterans’ disability ratings and the compensation they will receive for their injuries. Stacks of paper files — including veterans’ evidence from DOD of their military service and injuries — sit at VA regional offices waiting to be processed instead of being readily accessible in electronic files. Although Congress repeatedly has demanded an “integrated” and “interoperable” electronic health-records system, neither the DOD nor the VA is able to completely access the other’s electronic records.
