Abstract：
OBJECTIVE: In 2019, the Global Leadership Initiative on Malnutrition (GLIM) suggested a 2-step diagnostic format for malnutrition including screening and diagnosis. Prospective validation and feasibility studies, using the complete set of the five GLIM criteria, are needed. The aims of this study were to determine the prevalence of malnutrition, and investigate how the prevalence varied with mode of screening. Furthermore, we assessed the feasibility of GLIM in geriatric patients.
METHODS: Consecutive patients from two acute geriatric wards were included. For screening risk of malnutrition, the Mini Nutritional Assessment-Short Form (MNA-SF) or Malnutrition Screening Tool (MST) were used. In accordance with GLIM, a combination of phenotypic and etiologic criteria were required for the diagnosis of malnutrition. Feasibility was determined based on % data completeness, and above 80% completeness was considered feasible.
RESULTS: One hundred patients (mean age 82 years, 58% women) were included. After screening with MNA-SF malnutrition was confirmed by GLIM in 51%, as compared with 35% after screening with MST (p = 0.039). Corresponding prevalence was 58% with no prior screening. Using hand grip strength as a supportive measure for reduced muscle mass, 69% of the patients were malnourished. Feasibility varied between 70 and 100% for the different GLIM criteria, with calf circumference as a proxy for reduced muscle mass having the lowest feasibility.
CONCLUSIONS: In acute geriatric patients, the prevalence of malnutrition according to GLIM varied depending on the screening tool used. In this setting, GLIM appears feasible, besides for the criterion of reduced muscle mass.

摘要：
目标：2019年，全球营养不良领导倡议（GLIM）提出了营养不良的两步诊断格式，包括筛查和诊断。前瞻性验证和可行性研究，使用完整的五个GLIM标准，是需要的。这项研究的目的是确定营养不良的患病率，并调查患病率如何随筛查模式而变化。此外，我们评估了GLIM在老年患者中的可行性.
方法：纳入两个急性老年病房的连续患者。为了筛查营养不良的风险，使用迷你营养评估短表格(MNA-SF)或营养不良筛查工具(MST)。根据GLIM，营养不良的诊断需要结合表型和病因学标准.可行性是根据%数据完整性确定的，80%以上的完整性被认为是可行的。
结果：100名患者（平均年龄82岁，58％的妇女）被包括在内。经MNA-SF筛查后，51%的GLIM证实营养不良，与MST筛查后的35%相比（p=0.039）。在没有事先筛查的情况下，相应的患病率为58%。使用手握力作为减少肌肉质量的支持措施，69%的患者营养不良。对于不同的GLIM标准，可行性在70%到100%之间变化，以小腿围为代表的肌肉质量减少的可行性最低。
结论：在急性老年患者中，根据GLIM,营养不良的患病率因使用的筛查工具而异.在此设置中，GLIM似乎可行，除了肌肉质量降低的标准。
