在退伍军人健康管理局（VHA）内，输入电子医疗记录的人体测量值存储在地方信息系统、国家企业数据仓库（CDW）、本文描述了在CDW中检查体重和身高数据质量的努力，并将CDW数据与VHA的几个区域医疗保健设施组（退伍军人综合服务网络[VISNs]）维护的仓库中的数据进行比较。我们发现，尽管偶尔出现异常，但CDW和VISN数据源中记录的身高明显少于体重。CDW和VISN仓库中记录的数量和价值的一致性通常为97%至99%或更高，在同一天和同一年的高度和体重中发现了难以置信的变化，这表明测量或数据输入错误。我们的工作表明，随着时间的推移，通过验证，已经成为一个普遍可靠的人体测量数据来源研究人员应该评估包含在任何来源的数据的可靠性和应用策略，以尽量减少数据错误的影响适合他们的研究人群
Within the Veterans Health Administration (VHA), anthropometric measurements entered into the electronic medical record are stored in local information systems, the national Corporate Data Warehouse (CDW), and in some regional data warehouses This article describes efforts to examine the quality of weight and height data within the CDW and to compare CDW data with data from warehouses maintained by several of VHA's regional groupings of healthcare facilities (Veterans Integrated Service Networks [VISNs]) We found significantly fewer recorded heights than weights in both the CDW and VISN data sources In spite of occasional anomalies, the concordance in the number and value of records in the CDW and the VISN warehouses was generally 97% to 99% or greater Implausible variation in same-day and same-year heights and weights was noted, suggesting measurement or data-entry errors Our work suggests that the CDW, over time and through validation, has become a generally reliable source of anthropometric data Researchers should assess the reliability of data contained within any source and apply strategies to minimize the impact of data errors appropriate to their study population
