Veterans Affairs Corporate Data Warehouse (VA CDW)
VA CDW is a repository comprising data from multiple Veterans Health Administration (VHA) clinical and administrative systems. VHA is one of the largest integrated healthcare systems in the United States with data from over 20 years of sustained electronic health record (EHR) use. VA CDW was developed in 2006 to accommodate the massive amounts of data being generated and to streamline the process of knowledge discovery to application. The registry consists of approximately 7,500 databases hosted across 86 servers. Information that appears in the VA CDW includes demographic information, information on medication dispensing from VA pharmacies, laboratory test result information, free text from progress notes and radiology reports, as well as billing and claims-related data.
