InterSystems Database Technology Delivers Connectivity for Full Deployment to 102 DoD Hospitals

Cambridge, Mass.—February 10, 2003—InterSystems Corporation today announced that its post-relational CACHÉ database is the enabling technology for a real-time data access framework that enables users to access years of legacy data using industry standard desktop tools. The Medical Data Access Real-Time (MDAR-T) framework is now being rolled out to all 102 Department of Defense Army, Navy, Marine and Air Force Military Treatment Facilities worldwide. The announcement came this week at the HIMSS 2003 conference in San Diego.

The Goal: Real-time Data Mining

MDAR-T was developed in order to address the challenge of mining patient information stored in the Composite Health Care System (CHCS) database used by military training facilities. CHCS stores patient data including demographics, medical procedures, tests and pharmaceutical information. Until recently, this valuable information was accessible only through ad hoc reporting of legacy data, which could result in less than optimal healthcare decisions when the information wasn’t current.

“The objective is to maintain the integrity of the current CHCS back-end system and data while also enabling real-time access to the patient information without having a negative impact on the performance of CHCS,” explains LtCol Tony Smith, USAF, DoD CHCS Project Manager, Office of the Secretary of Defense Clinical Information Technology Program Office.

CACHÉ was selected to provide connectivity to the legacy CHCS database and to expose the database to object and SQL tools, technologies, applications and development environments that were previously unavailable without hand coding thousands of connections and mappings.

“Basically, MDAR-T makes previously unavailable information easily accessible to DoD healthcare professionals,” says Paul Grabscheid, InterSystems vice president of strategic planning. “It enables use of enterprise-wide reporting without data duplication and with minimal load on the existing system. As a result, database queries can be handled even during peak duty hours rather than resorting to running queries off-peak or overnight. Healthcare professionals get up-to-date, critical patient information when they most need it, and there is a positive impact on military medical readiness.”

From Alpha Test to Full Deployment

The initial MDAR-T field test was completed successfully by the end of 2002. SAIC, a systems integration, research and engineering company headquartered in San Diego, provided the integration and security for the initial MDAR-T implementation. SAIC and the Clinical Information Technology Program Office initiated the new system rollout to 102 locations worldwide in early 2003. InterSystems projects that the system will eventually be supporting real-time access to several million electronic patient records.

“The CHCS real-time data connection will permit a live data feed to be used in future development of Web applications,” notes Grabscheid. “That sets the stage for a variety of e-healthcare initiatives such as preventive health assessment, surgery tracking and population health management that may be of interest to the Department of Defense in the future.”
