Delivering Major Patient Safety Benefits Across Population of Three Million

Cambridge, Mass. – October 25, 2005 – InterSystems Corporation today announced that Partners HealthCare System, Inc. has gone live with a new Enterprise Master Patient Index (EMPI) system built on InterSystems’ CACHÉ post-relational database.

The leading database provider in healthcare, InterSystems develops and markets the CACHÉ post-relational database and the Ensemble universal integration platform.

Recognized worldwide for the ability to leverage innovative information technology, Partners is an integrated delivery system that offers patients a continuum of coordinated high-quality care. The system includes primary care and specialty physicians, community hospitals, the two founding academic medical centers, specialty facilities, community health centers, and other health-related entities.

Maximizing Care Delivery With Advanced Object Technology

CACHÉ delivers high performance, massive scalability and innovative object technology that were key drivers in the decision to build a new EMPI system in-house, according to Steve Flammini, Partners CTO. “Our previous system, built on traditional relational database technology, had been running for about a decade,” he explained. “Basically, we took all of the lessons we learned over the life of that system, identified all of the new capabilities we wanted, and the results were the specifications for a new ‘dream system’”, he said.

The ability to customize the application for Partners’ specific needs was one key element in the decision to bring EMPI system development in-house. In addition, the robust CACHÉ’ object technology and capabilities fulfilled criteria based on an IT strategy calling for the new application to utilize object architecture. The high performance and scalability CACHÉ is delivering for a wide variety of Partners applications also contributed to the selection of CACHÉ as the database foundation for the new system. “CACHÉ is the underlying database for many of our clinical applications,” Flammini said. “InterSystems is recognized for technology innovation and our working partnership has been highly successful for more than a decade.”

The new EMPI systems went live in July 2005 with a rollout throughout the Partners network. “The EMPI application effectively provides a crosswalk of patient information across multiple sites,” Flammini explained. Core patient demographics and information about patient visits is stored in the EMPI database. Because the EMPI establishes a patient’s identity across the Partners network, a physician in any location can access critical patient data from multiple institutions seamlessly. “The physician has complete access to the patient’s in-network history. This results in significant benefits in terms of patient safety across a population of about three million that we serve.”

The fast performance of the CACHÉ-based application has proven key to handling the high volume of information requests received on a 24 x 7 basis. Typically, the EMPI system responds to more than 20 million service requests from other applications and more than 100,000 transactions each day.

While the system has been running on a production basis for only about three months, “the move from a purchased application to a CACHÉ-based application developed and maintained in-house is already perceived as an organizational success,” according to Flammini. “Benefits such as more rapid system response, faster access to rich data, the ability to prioritize enhancements and customizations in the most optimal way possible, and having complete control over the development cycle are likely to deliver a rapid return on our technology investment,” he added.

“It is well recognized that EMPI systems are central to the realization of a seamless electronic medical record across a healthcare community. EMPI systems are highly complex and extremely challenging to develop and implement,” noted Paul Grabscheid, InterSystems Vice President of Strategic Planning, “and Partners has set a new standard for healthcare technology innovation with its new CACHÉ-based EMPI implementation. It’s been a privilege to work with their IT staff on this initiative.”
