The Department of Veterans Affairs (VA) Nutrition Status Classification scheme uses clinical data that are routinely collected on admission or shortly thereafter for quick inpatient nutrition screening. In this scheme, patients are assigned to 1 of 4 classification levels according to 7 individual indicators. The indicators include nutrition history, unintentional weight loss as a percent of usual body weight, percent of ideal body weight, diet, diagnosis, albumin, and total lymphocyte count. After ratings (1 to 4) are assigned to each of the 7 indicators, overall nutritional status for each patient is determined by an algorithm. The VA classification system includes many of the same criteria used in other nutritional status classifications. Where it differs is in the greater emphasis on the use of objective criteria and in the rigorous evaluation of reliability and validity that went into its development. Because of these extra measures, the VA classification can be used for prioritizing workload, as well as for determining staff requirements and for comparing workload and productivity across health care facilities. So that others might benefit from using this system, this article provides information on how the classification scheme was developed and explains how it is used.
退伍军人事务部（VA）营养状况分类方案使用入院时或入院后不久常规收集的临床数据进行快速住院患者营养筛查。在此方案中，患者根据7项个体指标被分为4个分类级别中的1个。这些指标包括营养史、非故意体重减轻占通常体重的百分比、理想体重百分比、饮食、诊断、白蛋白和总淋巴细胞计数。在给7项指标中的每一项都赋予评分（1至4）后，通过算法确定每位患者的总体营养状况。VA分类系统包括许多其他营养状况分类中使用的相同标准。其不同之处在于更加强调使用客观标准，以及在其开发过程中对可靠性和有效性进行严格评估。由于这些额外措施，VA分类可用于确定工作量优先级、确定人员需求以及比较不同医疗机构的工作量和生产率。为使其他人可能从使用该系统中受益，本文提供了有关分类方案如何制定的信息，并解释了其使用方法。
