Case Study: Department of Veterans Affairs achieves integration of 130 systems and improved patient care with InterSystems Ensemble

The U.S. Department of Veterans Affairs Uses InterSystems Ensemble ® to Integrate 130 Systems and Improve Patient Care

The U.S. Department of Veterans Affairs (VA), which operates over 1,300 facilities and cares for more than 5.4 million veterans annually, sought to enhance its My HealtheVet portal by integrating it with the VistA electronic medical record. The challenge was to create a fully integrated personal health record and secure messaging system that required connecting My HealtheVet with more than 130 enterprise systems across the country.

Using InterSystems Ensemble, the VA rapidly built a scalable integration layer that matches users via the master patient index, delivers EMR data through web services, and enables secure patient‑physician messaging that can be posted as EMR progress notes—development was completed by a small team in about a year. The result is an integrated personal health record used by 540,000+ registered users (and millions of prescription refills), improved patient engagement, streamlined workflows, fewer trips to VA facilities, reduced appointment‑desk calls, and a reliable high‑performance platform for future services.
