Veteran Identity Records from VA Healthcare Facilities

As of June 2010, the Master Veteran Index database contained over 17 million patient entries from all VHA facilities nationwide. It serves as the authoritative identity service for VA clients, establishing and synchronizing identities to enable an enterprise-wide view of patient information.

• Analyze patient identity correlation patterns across VistA and external systems like the Department of Defense.
• Support health information sharing initiatives by linking patient information via the access point mechanism.
• Assess the integration of legacy systems with the MVI framework for coordinated healthcare delivery.

Strengths
