目的 探索微型营养评估简易法（MNA-SF）能否客观、正确地评估老年住院患者的营养状况以及对临床预后进行预测。 方法 选择2012年3月－4月四川大学华西医院新入院老年患者407例，平均年龄（75.4 ± 7.10）岁，以MNA-SF评估其营养状态并根据营养状态分为两组，随访至出院或住院第30 d，分析其营养状况与住院时间，住院费用，全身炎症反应综合征（SIRS），死亡等临床结局的相关性。 结果 营养不良者22.6%（92例），营养不良风险者31.9%（130例），营养状态良好者45.5%（185例）。其中34例营养不良者，18例营养不良风险者和4例营养良好者发生SIRS；另有11例营养不良者，7例营养不良风险者和1例营养良好者死亡。MNA-SF分值在0～7分的患者无论在发生SIRS还是临床不良结局方面显著高于分值为8～14分的患者（P＜0.05）。营养不良者住院时间为（14.6 ± 8.30）d，营养不良风险或营养良好者为（12.1 ± 7.99）d，差异具有统计学意义（P＜0.05）。 结论 MNA-SF是一可靠，简便易行，可以预测老年住院患者临床预后的营养评估工具。
With the acceleration of population aging, the health problems and care service needs of the elderly are increasing, while the capacity for family-based care is declining. To address these challenges, China has proposed the “integrated medical and nursing care” service model, which integrates medical and health services with elderly care. Geriatric medicine is one of the key technical components of this integrated service model. This study aims to construct a technical standard system for geriatric medicine within the integrated medical and elderly care services. It mainly includes the basic principles, overall framework, structure, and explanations of the geriatric medicine technical standard system, providing a technical and directional framework for the geriatric medicine technical standard system in the context of integrated medical and elderly care services.
