Description: Patient Flow Suite (PFS) is a web platform that connects and maintains interoperability between various Document Storage System (DSS) web-based applications including various services that provide interconnectivity to individual VistA and other VA-hosted services.

This technology utilizes Microsoft Structured Query (SQL) database.

PFS offers a user a single sign-on experience for any VistA application the user has been given access to via application-specific VistA menu options. Once logged into PFS, an authorized user can switch between various DSS web applications that are hosted within PFS while managing the user’s VistA menu contexts, offering seamless state management across multiple applications. Currently supported web applications and services in PFS are:
  • Consult Tracking Manager (CTM/ CTM+)
  • Comprehensive Care Coordination (C3)
  • Patient Queuing Service (PACE)
  • Order Tracking Manager (Radiology, Lab, Oncology, Dermatology)
  • Supply Chain Management (currently under development)
Note: This technology is not a considered a suite as the name suggests.

The TRM decisions in this entry only apply to technologies and versions owned, operated, managed, patched, and version-controlled by VA. This includes technologies deployed as software installations on VMs within VA-controlled cloud environments (e.g. VA Enterprise Cloud (VAEC)). Cloud services provided by the VAEC, which are listed in the VAEC Service Catalog, and those controlled and managed by an external Cloud Service Provider (i.e. SaaS) are not in the purview of the TRM. For more information on the use of cloud services and cloud-based products within VA, including VA private clouds, please see the Enterprise Cloud Solutions Office (ECSO) Portal at:
