Identifying Malnutrition in Emergency General Surgery (EGS): A Systematic Review

Raw data of all included studies

Methods
MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, trial registries, and relevant journals published between January 2000 and January 2022 were searched for studies of adult patients with any emergency general surgery diagnosis, managed conservatively or operatively, with an assessment of nutritional status. Mixed populations were included if more than 50 per cent of patients were emergency general surgery patients or emergency general surgery results could be separately extracted. Studies in which patients had received nutritional support were excluded. The protocol was registered with PROSPERO, the international prospective register of systematic reviews (CRD42021285897).
Results
From 6700 studies screened, 324 full texts were retrieved and 31 were included in the analysis. A definition of malnutrition was provided in 23 studies (75 per cent), with nutritional status being determined by a variety of methods. A total of seven nutrition screening tools and a total of nine ‘assessment’ tools were reported. To define malnutrition, the most commonly used primary or secondary marker of nutritional status was BMI, followed by albumin level.

所包含研究的原始数据

方法
对2000年1月至2022年1月期间发表在MEDLINE、Embase、护理与相关卫生文献累积索引、临床试验注册处以及相关期刊上的研究进行了检索，这些研究涉及任何急诊普通外科诊断的成年患者，无论其治疗方式为保守治疗或手术治疗，并对其营养状况进行了评估。如果超过50%的患者为急诊普通外科患者或急诊普通外科结果可以单独提取，则包括混合人群。排除接受营养支持的患者。研究方案已在PROSPERO国际前瞻性系统评价注册处（CRD42021285897）注册。

结果
从筛选的6700项研究中，检索到324篇全文，其中31篇纳入分析。23项研究（75%）提供了营养不良的定义，营养状况的确定采用多种方法。共报道了7种营养筛查工具和9种‘评估’工具。定义营养不良时，最常用的首要或次要的营养状况指标为BMI，其次是白蛋白水平。
