Malnutrition is common in hospitals and it is important to implement an appropriate nutrition screening tool to identify patients at risk. The aim of the study was to assess the sensitivity and specificity of the malnutrition screening tool developed by the Malnutrition Advisory Group of the British Association of Parenteral and Enteral Nutrition against subjective global assessment in hospitalised patients with cancer. A cross-sectional study assessing the risk of malnutrition and nutritional status of sixty-five hospitalised patients with cancer, aged 56 +/- 15 years. According to subjective global assessment, 25 % of patients were well nourished and 75% were malnourished (63% were moderately or suspected of being malnourished and 12% severely malnourished). The malnutrition screening tool had a low sensitivity of 59% and a specificity of 75%. The positive predictive value was 88% and the negative predictive value 38%. There were significant linear trends between subjective global assessment classification and percentage weight loss in the previous six months (P < 0.001) and body mass index (P = 0.007). The malnutrition screening tool developed by the Malnutrition Advisory Group of the British Association of Parenteral and Enteral Nutrition is not a suitable screening tool for detecting risk of malnutrition in hospitalised patients with cancer.
营养不良在医院中很常见，实施合适的营养筛查工具以识别有风险的患者很重要。本研究的目的是评估英国肠外与肠内营养协会营养不良咨询小组开发的营养不良筛查工具相对于主观全面评定法在住院癌症患者中的敏感性和特异性。一项横断面研究评估了65名年龄为56±15岁的住院癌症患者的营养不良风险和营养状况。根据主观全面评定法，25%的患者营养良好，75%的患者营养不良（63%为中度或疑似营养不良，12%为重度营养不良）。营养不良筛查工具的敏感性低，为59%，特异性为75%。阳性预测值为88%，阴性预测值为38%。主观全面评定法分类与前六个月体重减轻百分比（P<0.001）和体重指数（P=0.007）之间存在显著的线性趋势。英国肠外与肠内营养协会营养不良咨询小组开发的营养不良筛查工具不是检测住院癌症患者营养不良风险的合适筛查工具。
