The Corporate Data Warehouse (CDW) is a potentially important new data source within the Veterans Health Administration. This article describes an administrative project and a research study that examined the variability and reliability of weight and height data within the CDW and compares the data with the regional warehouse data. Our work suggests that the CDW is a generally reliable source of weight and height data. Challenges include relatively fewer recorded heights than weights and biologically implausible values and variation, which may reflect measurement or data entry errors. We discuss strategies to minimize the effect of these errors and policy changes that could improve data quality.
