Cambridge, Mass. – March 7, 2005 – InterSystems Corporation today announced that Providence Health System (PHS) has signed an agreement to license the Ensemble universal integration platform.

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

PHS operates 17 acute care hospitals, 12 freestanding long-term care facilities and 19 low income and assisted living facilities across a four-state area in the Pacific Northwest. The Ensemble agreement covers integration projects underway at PHS facilities in Washington.

Real-time Decision Support

The agreement covers a major integration project that involves real-time extraction, transformation, aggregation and loading of data, from up to 30 disparate systems, into a decision support system (DSS) from McKesson Corporation. “This information integration will enable us to more effectively analyze each patient’s experience across the healthcare continuum with the objective of improving outcomes and overall care delivery,” said Jerry Tonkovich, Project Manager at PHS in Seattle. The first set of interfaces went live in December 2004 and plans are to continue the production rollout on an aggressive implementation schedule during early 2005.

Ease of use and the comprehensive range of Ensemble adapters were key selection criteria for PHS, according to Tonkovich. “Most large hospitals have multiple departmental applications and databases. Ensemble offers the wide variety of adapters needed in healthcare. And, the Ensemble rules engine has been designed so that business analysts can make changes themselves, rather than having to call in technical specialists,” he said. “We examined other integration approaches and Ensemble was clearly the right choice.”

“We’re seeing accelerated movement in the healthcare sector to build and deploy integration projects that enable creative new uses of clinical and financial information,” said Trevor Matz, InterSystems Managing Director, Ensemble. “It’s a pleasure to work with PHS on an integration initiative that supports their leadership in using information technology to enable delivery of top-tier healthcare.”
