VISTA Data Project
The Veterans Information Systems Technology Architecture (VISTA) is the U.S. Department of Veterans Affairs integrated longitudinal clinical, business, and administrative information system that supports the operations of over 1200 VA hospitals and clinics nationwide.
The VISTA Data Project is a new data-centric, model-driven approach to VA master data management, interfacing, and security. VISTA's data model - the roadmap to all of VA's institutional, business, and clinical processes and data - has evolved organically over the past 35 years, but has not been surfaced and leveraged in computable form.
Now, for the first time, VA's native transactional clinical and business data model - the VISTA Data Model - will be comprehensively exposed, enriched, and operationalized as a single, secure, symmetric read-write, server-side interface for all clinical operational VISTA data.
The VISTA Data Model is in turn normalized across all local VISTA system data models to create a national, standardized Master Veteran Data Model (MVDM), allowing read-write transactions across all VA VISTA systems using a single, secure, veteran-centric, model-driven mechanism, MVDM Services:
The figure above summarizes the evolution from thousands of unique, inconsistent, insecure, unidirectional code-based interfaces to that of a single, standardized, secure, server-side, symmetric (bidirectional), service-based, master data model-driven interface.
