Master Veteran Index (MVI)

<p>As of June 28, 2010, the Master Veteran Index (MVI) database based on the enhanced Master Patient Index (MPI) is the authoritative identity service within the VA, establishing, maintaining and synchronizing identities for VA clients, Veterans and beneficiaries. The MVI includes authoritative sources for health identity data and contains over 17 million patient entries populated from all VHA facilities nationwide. The MVI provides the access point mechanism for linking patient's information to enable an enterprise-wide view of patient information, uniquely identifies all active patients who have been admitted, treated, or registered in any VHA facility, and assigns a unique identifier to the patient. The MVI correlates a patient's identity across the enterprise, including all VistA systems and external systems, such as Department of Defense (DoD) and the Nationwide Health Information Network (NwHIN). The MVI facilitates the sharing of health information, resulting in coordinated and integrated health care for Veterans. New Information Technology systems must be interoperable with the MVI and legacy systems will establish integration by October 1, 2012. The Healthcare Identity Management (HC IdM) Team within VHA's Data Quality Program is the steward of patient identity data, performing maintenance and support activities.</p>

截至2010年6月28日，基于增强型主患者索引（MPI）的资深退伍军人索引（MVI）数据库，作为美国退伍军人事务部（VA）内权威的标识服务，负责建立、维护和同步VA客户、退伍军人和受益人的身份信息。MVI数据库汇聚了健康身份数据的权威来源，包含来自全国所有退伍军人卫生行政机构（VHA）设施的超1700万患者记录。MVI提供了访问点机制，以便将患者信息与整个企业相连接，实现患者信息的全局视图，唯一标识所有在VHA任何设施中被接收、治疗或注册的活跃患者，并为每位患者分配一个唯一标识符。MVI在全局范围内关联患者的身份，包括所有VistA系统和外部系统，如国防部（DoD）和全国健康信息网络（NwHIN）。MVI促进了健康信息的共享，为退伍军人提供了协调一致和整合的医疗服务。新的信息技术系统必须与MVI和遗留系统兼容，而遗留系统将在此后至2012年10月1日之前建立整合。美国退伍军人事务部数据质量计划中的医疗保健身份管理（HC IdM）团队负责患者身份数据的保管，执行维护和支持活动。
