BlueCross BlueShield of Tennessee selects Teradata

Teradata big data analytics will support complex analysis for strategic and operational intelligence to drive positive health care outcomes

CHATTANOOGA, Tenn. — Teradata (NYSE: TDC), the analytic data solutions company, announced today that BlueCross® BlueShield® of Tennessee (BCBST), a leader in delivering innovative health care products, services and information to more than 3 million members, has selected Teradata for its Clinical Data Warehouse (CDW) analytic platform. BCBST has deployed the new Data Warehouse Appliance along with the Teradata Health Care Logical Data Model.

"The CDW will facilitate our organization’s ability to analyze ever larger and more diverse data sets to provide the analytic insight we need to meet our members’ needs and help better control the cost of health care in Tennessee," said Nick Coussoule, chief information officer, BCBST.

Coussoule said the new system will help BCBST analyze multiple terabytes of detailed data linked to millions of health insurance claims, patient experiences, doctors, hospitals, treatments, procedures and enrollment groups to answer complex questions and gain valuable insight into trends, costs and quality of care. "A key consideration in our selection process was Teradata's ability to fully comply with BCBST's stringent security policy that requires all BCBST data at rest be fully encrypted," Coussoule added. BlueCross BlueShield of Tennessee recently completed a $6 million effort to encrypt all at-rest data throughout its enterprise, giving members peace of mind that their personal information is secure.

"Our use of the new Teradata warehouse appliance – and the health care logical data model - will support complex analysis for strategic and operational intelligence, and requires real-time data load, with immediate information access to support the needs of a growing clinical practice," said Sherri Zink, vice president of Medical Informatics for BCBST, who manages the new clinical data warehouse. "The appliance will help us to identify the pattern variations in our delivery of treatment and identify best practices that produce optimal care and outcomes for our members."

The BCBST CDW mission is "to (1) improve clinical practice, (2) improve BCBST's ability to help manage the quality of health care and (3) provide policy makers with the ability to assess the impact of system changes on outcomes, quality, access, cost, and use of health care resources."

"Teradata helps leading companies like BCBST improve operating efficiencies and uncover new business insights that create competitive differentiation. This is accomplished through the ability to execute detailed analysis, cutting complex query times from weeks and days to minutes and seconds," said Rick Morton, vice president, Teradata financial services, insurance and health care industries. "Companies generally consider Teradata an ‘ROI buy’ due to the impressive economic returns so many of them experience as a result of the high speed, scalability and workload performance of our systems."

Teradata’s momentum continues in the health care industry as companies look for more powerful database analytics to help them thrive in the midst of cost pressures, significant competition and the changes driven by health reform.

Teradata’s health care customers include BKK (Germany), the Centers for Medicare and Medicaid Services, Centene, Express Scripts Inc., Aurora, Highmark, BCBS of North Carolina, INPS (Italy), Medibank Private (Australia), and many others.
