From NextGov.com: The Veterans Affairs Department plans to use data centers operated by the Defense Information Systems Agency to store its electronic health records as part of a project to develop a joint record for both departments.

Using DISA centers to store Defense and VA health records will eventually result in the largest electronic health record database in the world.

The Military Health System currently stores electronic health records for 9.6 million active-duty and retired military personnel in a 70-terabyte DISA database.

VA has 6.1 million veterans enrolled in its healthcare system, with records housed in multiple data centers already in the process of consolidation. VA did not answer a query on the total amount of data stored for its electronic health records, but an industry source who declined to be identified said it was close to the 70 terabytes stored by Defense.

The Defense official could not provide a precise timeline for the transfer of the VA health records to DISA.
