评分的患者生成主观整体评估工具（PG-SGA）被认为是识别癌症患者营养不良的最合适手段，但在繁忙的门诊环境中实施往往具有挑战性。我们评估了删节版PG-SGA （abPG-SGA）的有效性，该版本放弃了体格检查，并将其与完整的PG-SGA和营养不良筛查工具（MST）在识别营养不良方面的有用性进行了比较。采用SGA综合评分、PG-SGA、MST对90例肿瘤门诊化疗患者的营养状况进行评估。生成受试者工作特征（ROC）曲线，以估计各种营养不良分值的敏感性和特异性。36%的患者营养不良（SGA）。abPG-SGA的灵敏度为94%，特异性为78%，曲线下面积(AUC) = 0.956，略低于PG-SGA（灵敏度97%，特异性86%，AUC = 0.967），高于MST（灵敏度81%，特异性72%，AUC = 0.823）。患者报告的症状包括食欲不振（30%）、味觉改变（31%）、疲劳（30%）和日常生活活动能力下降（53%）。总之，abPG-SGA是一种实用的、信息丰富的、有效的检测肿瘤门诊患者营养不良的工具。
The scored Patient-Generated Subjective Global Assessment tool (PG-SGA), regarded as the most appropriate means of identifying malnutrition in cancer patients, is often challenging to implement in a busy outpatient setting. We assessed the validity of an abridged version of the PG-SGA (abPG-SGA), which forgoes the physical examination, and compared its usefulness in discerning malnutrition to the full PG-SGA and Malnutrition Screening Tool (MST). The nutritional status of 90 oncology outpatients receiving chemotherapy was assessed according to SGA global rating, PG-SGA, and MST. Receiver operating characteristic (ROC) curves were generated to estimate the sensitivity and specificity of various cut-off scores for malnutrition. Thirty-six percent of patients were malnourished (SGA). The abPG-SGA yielded 94% sensitivity and 78% specificity and area under the curve (AUC) = 0.956, which was slightly lower than PG-SGA (97% sensitivity, 86% specificity, AUC = 0.967) and higher than MST (81% sensitivity, 72% specificity, AUC = 0.823). Patient reported symptoms included loss of appetite (30%), altered taste (31%), fatigue (30%), and decreased ability to perform activities of daily living (53%). In conclusion, the abPG-SGA is a practical, informative and valid tool for detecting malnutrition in the outpatient oncology setting.
