Projects Improved Ambulatory Care Delivery, Revenue Protection of $200K-Plus

Cambridge, Mass. – February 14, 2005 – InterSystems Corporation today announced that CareGroup HealthCare System has completed the rollout of a Web-based electronic health record (EHR) throughout the Beth Israel Deaconess Medical Center (BIDMC) ambulatory care network. The implementation, which is expected to reduce the potential for medical errors in ambulatory care delivery as well as significantly increase Medicare revenues, is built on the CACHÉ post-relational database. InterSystems highlighted the EHR implementation at the HIMSS 2005 conference in Dallas, Texas.

The leading database provider in healthcare and number two embedded database worldwide, InterSystems develops and markets the CACHÉ post-relational database and the Ensemble universal integration platform. CareGroup is an integrated delivery network that offers a broad spectrum of health services to residents of Eastern Massachusetts, in a variety of settings ranging from world-renowned academic health centers and outstanding community hospitals, to physician offices and community health centers.

High Performance, RAD Features, Scalability Critical for Success

“We have a long history of successful Web implementations based on CACHÉ,” said CareGroup CIO John Halamka. “Its ability to support rapid application development, and to deliver top-tier application performance and enterprise scalability have made it an integral component of our overall IT strategy. So, when the time came to deliver a patient EHR to ambulatory care providers in remote locations, CACHÉ was the right database choice.”

Rollout of the multi-county system, dubbed WebOMR, began in early 2004 with the final locations in the BIDMC network going live in December. The remainder of the 72 ambulatory care practices associated with CareGroup will be going live with WebOMR this year and the patient information is also available on a view-only basis to qualified referring physicians. “WebOMR is, in effect, our major strategy for sharing clinical information in our community,” Halamka noted.

Improved Care, Medicare Revenue Protection

CareGroup is projecting significant care delivery benefits from the recently completed implementation. “The WebOMR includes an ambulatory clinical physician order entry (CPOE) component that reduces the potential for medical error,” Halamka explained. “By automatically checking orders for possible negative medication interactions or patient drug allergies, for example, the chance for negative medication impact is cut dramatically,” he said.

The ambulatory CPOE component of the WebOMR system will be used for approximately two million outpatient encounters annually. It is estimated that Web-based POE systems prevent about 50 percent of medical errors, according to the Center for Information Technology Leadership (CITL), a research organization established to help guide the healthcare community in making more informed strategic IT investment decisions. At a national level, CITL’s analysis shows that ambulatory CPOE systems can avoid more than two million adverse drug events annually, 130,000 of which are life-threatening. “It’s clear that the care delivery improvement made possible by the CACHÉ-based WebOMR CPOE component alone will be very important,” said Halamka.

Cost savings projections from the WebOMR implementation are equally positive. For example, CITL’s model projects annual savings of approximately $44 billion with nationwide implementation of advanced ambulatory CPOE systems. “CareGroup expects to realize a proportional amount of those savings,” Halamka said. In addition, the WebOMR makes it easier to provide Medicare with all of the billing information and documentation within the timeframe necessary to receive reimbursement. CareGroup estimates revenue protection of hundreds of thousands of dollars annually made possible by the ability of the WebOMR to speed up Medicare information delivery.

“By making it possible for physician notes and patient information to be shared among all of our providers, WebOMR not only enhances communication but will result in increased billing because of documentation improvements. It’s a winning scenario for everyone in our network,” Halamka said.

“WebOMR is the latest evidence of the innovation that has made CareGroup a leader in effectively leveraging information technology in healthcare,” said Paul Grabscheid, InterSystems Vice President of Strategic Planning. “We are very proud of our long working partnership with this visionary healthcare organization.”
