'The Department of Veterans Affairs (VA) and the Department of Defense (DoD) are working together to fundamentally and positively impact the health outcomes of Veterans, Service members, and their dependents. Achieving interoperability of health records between the two Departments is the chief goal motivating the Departments� electronic health record (EHR) efforts. Seamless integration of health data from VA, DoD, and other healthcare partners enables clinicians and patients to benefit from the availability of a complete longitudinal health record, achieving the goal of developing electronic records that will transition along with them from active-duty to retired status.The Departments are on complementary paths for modernizing their respective EHR systems, replacing or enhancing existing systems as required to support delivery of the best possible care in their particular environments. For its part, VA will enhance, or evolve, its Veterans Health Information Systems and Technology Architecture (VistA) EHR to achieve its interoperability, clinical, and technical objectives. This VistA Evolution Program Plan captures VA�s structured approach to executing this mission.'
