Throughout Multi-Hospital Division

Quovadx, Inc. (Nasdaq: QVDX), a leading provider of software and services enabling Competitive Process Advantage, today announced that Adventist Health System, the largest not-for-profit Protestant healthcare organization in the U.S. serving nearly 2 million patients annually with 38 hospitals totaling nearly 6,000 licensed beds, has selected QDX(TM) Platform V.

After a two-year assessment, Adventist Health System has decided to replace its current interface engine from SeeBeyond with QDX Platform V from Quovadx. QUOVADX(TM) technology will be implemented in 28 facilities, approximately 3,700 beds, within the Multi-Hospital Division of Adventist Health System.

"Florida Hospital, a sister division within Adventist Health System, currently utilizes QUOVADX technology," said Jeff King, Director of Technical Services at SSCI, a subsidiary of Adventist Health System. "They are extremely pleased with the technology as well as their level of service and support from Quovadx. The functionality of QDX Platform V will allow Adventist Health System to better serve our users and patients with more efficient and reliable data transactions across systems throughout the organization."

The implementation of QDX Platform will standardize the integration technology across a majority of the Adventist Health System enterprise. Quovadx was selected due to its focus on the healthcare industry and the unique requirements and constraints of its practices. QDX Platform V is able to run on the platform and operating system of choice, IBM pSeries (RS/6000) with AIX. Through XML capabilities and ODBC options, QUOVADX technology also provides Adventist Health System with the opportunity to expand its technology investment in the future.

"Quovadx continues to see growth in the healthcare provider market," said Debbie Dean, executive vice president of product management for Quovadx. "Healthcare organizations need strategic business partners to deliver flexible solutions for an evolving marketplace. Quovadx provides the tools to speed development, reduce operational costs and improve productivity, resulting in increased user and patient satisfaction. We're looking forward to working with Adventist to meet the specific needs of its implementation as well as future projects."
