The Pharmacy Data Warehouse Initiative went live on the MHS Information Platform as of Friday, May 24, 2024. This initiative, now known as the MHS Information Platform-Pharmacy Data Warehouse, encompasses the design, development, and implementation of a capability comparable to the Pharmacy Operation Division's legacy contractor-owned and contractor-managed PDW. By leveraging MHS Information Platform tools and technologies, the MHS Information Platform-Pharmacy Data Warehouse addresses the current needs and requirements of PDW users.

The MHS Information Platform-Pharmacy Data Warehouse incorporates legacy pharmacy data and interfaces with existing systems, including TPharm input data, LexisNexis, National Council for Prescription Drug Programs, and First Data Bank reference files.

The Defense Health Agency, formerly the TRICARE Management Activity, directed the initial development and implementation of the PDW in 1999. This resulted in a cost-efficient, integrated patient drug profile designed to protect the health and welfare of the Department of War beneficiary population. The MHS Information Platform-Pharmacy Data Warehouse serves as a central repository for prescription medications dispensed to TRICARE beneficiaries, enabling the DHA to monitor and track drug utilization, analyze provider prescribing patterns, reduce costs, prevent fraud, and improve the quality of prescription services for TRICARE beneficiaries.

With the go-live of the PDW within the MHS Information Platform, all MHS pharmacy data is now housed in the Amazon Web Services Government Cloud, benefiting from enhanced cyber monitoring and controls. Furthermore, all MHS pharmacy data is now stored in a government-owned/government-operated warehouse, centrally located within DHA, providing improved access for authorized users.
