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."
