Streamlined integration and real-time services help VA teams modernize applications while maintaining continuity of care
Throughout the years, the Department of Veterans Affairs has been attempting to modernize its legacy systems capabilities as part of its digital transformation efforts and improved Veteran health care.
Traditionally, developing interfaces to the Veterans Health Information Systems and Technology Architecture (VistA) requires extensive custom coding and manual work. These processes slowed down modernization efforts, introduced inefficiencies, and created additional administrative burden for VA teams.
To meet this challenge, DSS developed VSOA Enterprise, or VistA Service-Oriented Architecture (VSOA), an enterprise-grade middleware solution designed to simplify integration with VistA and related health care systems. By leveraging a low-code/no-code framework, VSOA.
VSOA Enterprise eliminates the need to build custom interfaces from scratch. Through configuration-based deployment, the solution provides standards-based RESTful (Representational State Transfer) web services with JSON (JavaScript Object Notation) payloads, enabling real-time, bidirectional data exchange. This approach saves time and resources, reduces errors, and allows for seamless connectivity between new applications and existing VistA logic.
VA teams can also orchestrate multiple VistA services within a single workflow, streamlining end-to-end processes such as patient encounters, lab orders, or care coordination tasks. This orchestration helps avoid duplicative work and ensures consistency across clinical and administrative systems.
With high performance, resilient network connectivity, and built-in DevOps tooling, VSOA Enterprise is optimized for enterprise-scale deployments.
The system supports load balancing, multi-institutional access, and simultaneous connections to over 130 VistA sites. This scalability empowers VA facilities to maintain real-time visibility across a wide range of services while reducing the burden on local IT teams.
Security and compliance are also central to VSOA Enterprise. The solution follows VA Handbook 6500, integrates with IAM-based Single Sign-On, and supports OAuth 2.0 authentication. These features make sure that data is exchanged securely while enabling efficiency through automated session management and connection pooling.
By reducing the complexity of VistA integration and delivering modern middleware capabilities, VSOA Enterprise allows VA teams to focus on outcomes rather than infrastructure. Applications can be deployed faster, workflows become more efficient, and providers gain more reliable access to the information they need.
This efficiency directly translates into improved care for Veterans. Whether through faster application development, streamlined workflows, or real-time access to clinical data, VSOA Enterprise empowers the VA to advance modernization goals while ensuring safe, coordinated, and timely care delivery.
