摘要
主观综合性营养评价法(SGA)虽在临床应用广泛,但对其用途及评价结果的临床意义,各家报道差异甚大。有些研究将其视为筛选营养风险的工具;有些将其视为预测病人预后的工具,甚至将其视为评价其他营养评价方法或指标的参照值。不同营养状况评价指标所反映出的营养状况改变的侧重点不同。故临床应针对不同病人采用不同的评价方法或指标,以客观和有所侧重地评价病人的营养状况,为实施营养干预提供依据。
The Subjective Global Assessment （SGA） is widely applied in the clinic. The usage and the clinical purpose of SGA is quite different among the various studies. In some studies, SGA proved to be a good screening tool for nutritional risk or a prognostic indicator for poorer outcomes. In several clinical setting, SGA was employed as a ＂gold standard＂ method against which new nutritional assessment methods were validated. At present, the different indicators of nutritional assessment reflect the different characteristics of the body＇s nutritional status changes. The different indicators and methods should be incorporated according to the patient in order to objectively and correctly assess the patient＇s nutritional status.
