Clinical application and evaluation of the nutritional risk screening 2002 Abstract Clinical application and evaluation of the nutritional risk screening 2002 Abstract Part I Preliminary screening of inpatient nutritional risk Objective We aimed to screen nutrition risk of hospitalized patients,and then analysis the large sample datas, and proposed the different disciplines of nutritional risk between hospitalized patients. Methods Totally 33 thousand adult patients in 7 departments of Shanghai Sixth People's Hospital were enrolled from August 2009 to December 2011 by fix-point consecutive sampling. Nutritional Risk Screening 2002(NRS-2002) was performed and nutritional support was evaluated in all patients. Results 1.Overall prevalence of nutritional risk was 24.6%. 2.The over all prevalence of nutritional risks in General Surgery was 15.7 %.Patients with gastrointestinal and hepatobiliary and pancreatic diseases had higher risks than others, which were 36.0% and 64.0%. The total nutritional risk in Medicine is higher than Surgery,especially Respiratory Medicine,Neurology Medicine,Digestive Medicine had the higher prevalence of nutritional risk, which were 44.3% 38.8% and 35.1%. 3. Compared to the medicine departments, surgical patients at nutritional risk have higher nutritional support rates,which was 44.1%; especially gastrointestinal tumors diseases,which were 84.8% and 64.1%, while nutritional support rate of the other surgical diseases was relatively low.

Abstract Clinical application and evaluation of the nutritional risk screening 2002 Conclusions The prevalence of surgical patients nutritional risk was significantly lower than medicine departments, but nutrition support in surgery is higher than medicine. Malnutrition and nutritional risk were not only the issues surgical departments need to focus on, but also medicine department should. Key words NRS-2002 ;Nutritional support ; Nutritional risk ;General Surgery; Medicine Part II Investigate nutritional risk and nutritional support in hospitalized patients with gastrointestinal tumors Objective To investigate the status of nutritional risk as well as nutritional support in patients with gastrointestinal tumor. Methods In this prospective cohort study, patients with gastrointestinal tumor were recruited from September 2009 to June 2011. Patients were screened by using Nutritional Risk Screening 2002 (NRS-2002) at admission. Data of the nutritional risk, application of nutritional support, complications, and tumor staging were collected. Results Nine hundred and sixty-one patients with gastrointestinal tumor were enrolled,the overall prevalence of nutritional risk was 38.9% (374/961) at admission,49.2% in gastric tumor and 32.8% in colorectal tumor,respectively. The highest prevalence was found in stage Ⅳ gastric tumor 87.3%,and colorectal tumor 58.8% while the lowest prevalence was found in stage ⅡA gastric tumor 16.1% and stageⅠcolorectal tumor 9.8%. 62.3% (152/244) of gastric tumor patients with nutritional risk while 48.6% (144/296) without nutritional risk received nutritional support. 37.7% (92/244) of colorectal tumor patients with nutritional risk while 51.4% (152/296) without nutritional risk received nutritional support. The ratio of parental nutrition and enteral VI
Clinical application and evaluation of the nutritional risk screening 2002 Abstract nutrition was 1.25:1. The rate of complications in the gastrointestinal tumor patients with nutritional risk was higher than that in the patients without nutritional risk (32.4% VS 20.4%, P=0.000). For the gastrointestinal tumor patients with nutritional risk, the complication rate of the patients with nutritional support was significantly lower than that of the patients without nutritional support (27.5% VS 40.8%,P=0.0086). For the gastrointestinal tumor patients without nutritional risk, the complication rate of gastric tumor patients with nutritional support was significantly lower than that of the patients without nutritional support (P=0.0396), while the complication rate was not significantly different in the colorectal tumor patients with nutritional support or not (P=0.4647). Conclusions Patient with gastrointestinal tumor has a high nutritional risk which is related to tumor staging. Patients with nutritional risk have more complications, and nutritional support is beneficial to the patients with nutritional risk by a lower complication rate. Key words NRS-2002 ;Nutritional support; Nutritional risk; Gastrointestinal tumor; Complications; Tumor staging Part III Investigate nutritional risk and clinical outcomes in hospitalized patients with hepatobiliary and pancreatic diseases by using NRS2002 Objective To investigate nutritional risk and nutritional support in hospitalized patients with hepatobiliary and pancreatic diseases, and to analysis the relationship between nutritional risk and clinical outcomes. Methods In this prospective cohort study, patients with hepatobiliary and pancreatic diseases were recruited from July 2011 to January 2012. Patients were screened by using Nutritional Risk Screening 2002 (NRS-2002) at admission. Data of the nutritional risk, application of nutritional support, complications and length of stay were collected. VII
Abstract Clinical application and evaluation of the nutritional risk screening 2002 Results Four hundred and eleven patients with hepatobiliary and pancreatic diseases were recruited, the overall prevalence of nutritional risk was 20.6% at admission,59.3% in liver cancer, 32% in the bile duct cancer,while the lowest nutritional risk was found in liver cysts (4.4%). The rate of complications in the patients with nutritional risk was higher than in the patients without nutritional risk(44.7% VS 19.6%,P<0.001).Serious complications in patients with nutritional risk were not significant different with patients without nutritional risk(34.2% VS 32.8 %,P=0.885). For the patients with nutritional risk,the complications rates and the average length of stay of patients with nutritional support were significant lower than those without nutritional support (38.1%VS 63.6%, P=0.038;15.41±2.47d VS 17.00±3.38d,P=0.021);For the patients without nutritional risk, the complications of patients with nutritional support was significant higher than those without nutritional support (21.9% VS 17.5%,P=0.319),while the average length of stay of patients with nutritional support was significant longer than those without nutritional support (12.75±2.63d VS 11.75±2.97d,P=0.002). Conclusions Patients with hepatobiliary and pancreatic diseases have a higher nutritional risk in malignant disease,and patients with nutritional risk have more complications nutritional support is beneficial to the patients with nutritional risk by improving clinical outcomes.

NRS-2002 营养风险筛查的临床应用及评价 前言 前言 1. 营养风险概念 2002 年欧洲肠内肠外营养学会 (ESPEN) 专家组在 128 个随机对照临床研究 (randomized controlled clinical trials,rct) 的基础上, 提出了一个有循证医学依据的营养风险筛查工具 (NRS-2002,nutritional risk screening 2002 ) [1], 并在 2003 年给出了 营养风险 较为明确的定义 营养风险的概念可概括为 现存的或潜在的营养和代谢状况影响疾病或手术后临床结局的风险, 也可理解为 营养风险是指现存的或潜在的营养因素导致患者出现不良临床结局的风险 营养风险与营养不良 ( 不足 ) 营养不良风险在内涵上有很大差别 营养风险是指营养因素导致不良临床结局的风险, 而营养不良风险只是指发生营养不良的风险, 不涉及临床结局 营养不良用来描述现存的营养受损状态 营养风险概念的发展所基于的假设是营养支持不仅适用于已有营养不良的患者, 而且也适用于由于疾病 手术或创伤导致的应激代谢状态, 营养需要量增加的患者 营养风险概念的范围要比营养不良 ( 不足 ) 广泛 2. 为什么要进行营养风险筛查 1976 年 Bistrin 等报告, 住院患者营养不良发生率高达 70% 但 30 多年来, 大量调查显示, 住院患者的营养不良发生率已有了较大的不同 1994 年,Mc Whirter [2] 等报告, 以体质指数 BMI<20kg/m 2 为判定标准, 营养不良的发生率在普通内科患者中为 46%, 在呼吸内科患者中为 45%, 在普外科患者中为 27%, 在老年住院患者中为 43% 这表明营养不良在住院患者中是广泛存在的, 而且不只限于以往人们所关注的外科患者和重症患者 实际上, 内科系统的胃肠道疾病患者 肾病患者 神经系统疾病患者和呼吸系统疾病患者, 其营养不良的发生率高过外科择期手术患者 2002 年, Fettes [3] 等的调查显示, 腹部择期手术患者营养不良的发生率仅为 9% 2008 年由中华医学会肠外肠内营养学分会组织 蒋朱明教授进行的全国范围的多中心研究 [4], 对来自呼吸科 肾内科 消化内科 神经内科 普外科 胸外科等 6 专科的共计 15000 多例住院患者进行营养筛查, 结果显示, 总的营养不良发生率约为 10%, 营养风险发 1
前言 NRS-2002 营养风险筛查的临床应用及评价 生率为 35.6% Schiesser [5] 对 608 例胃肠手术患者的前瞻性研究显示, 有营养风险患者并发症发生率显著增高, 住院时间显著延长 Amaral [6] 研究发现, 有营养风险患者的平均住院费用比无风险患者高 20% 因此营养风险是预测临床结局的重要因素之一, 临床医师应重视住院患者的营养不良, 及时给予相应的营养支持, 避免不良的临床结局的发生 3. 常用营养状况评价方法目前, 在临床工作中应用的营养评定工具有 10 余种之多, 包括使用单一指标和复合指标两类 传统的单一指标包括以下 5 个方面的内容 : 膳食调查 ; 人体组成 ; 人体测量 ( 主要指标包括 BMI 三头肌皮褶厚度 上臂围 上臂肌围 握力和腰臀围比值等 ); 生化和实验室测定 ( 包括血清白蛋白 转铁蛋白 (TFN) 前白蛋白(PA) 视黄醇结合蛋白 (RBP) 氮平衡 肌酐身高指数(CHI) 血浆氨基酸谱测定 免疫功能测定等 ); 临床检查 : 通过病史采集及体格检查来发现营养缺乏的体征 早期研究已明确, 采用单一指标评定住院患者营养状况局限性多, 误差较大 近年来研究主要集中在探讨复合指标的筛查工具, 以提高筛查的敏感性和特异性 目前有多个筛选工具, 如主观全面评估 (SGA,subjective global assessment) 营养不良通用筛选工具 (MUST,malnutrition universal screening tool) 简易营养评估(MNA, mini-nutritional assessment) 营养风险指数(NRI,nutrition risk index) 以及营养风险筛查 2002(NRS-2002) 等 3.1 主观全面评定法 (SGA) 是美国肠外肠内营养学会 (ASPEN) 推荐的临床营养状况评估工具 其特点是以详细的病史与临床检查为基础, 省略人体测量和生化检查 有研究显示, 通过 SGA 评估发现的营养不足患者, 并发症的发生率是营养良好患者的 3~4 倍 但 SGA 作为营养风险筛查工具有一定局限性, 如 SGA 更多反映的是疾病状况, 而非营养状况 ;SGA 不适用于区分轻度营养不足, 侧重反映慢性或已存在的营养不足, 不能及时反映患者营养状况的变化 目前, 该筛查工具缺乏筛查结果与临床结局的证据支持, 同时因其未把观察指标和如何将患者进行分类直接联系起来, 使该工具不能满足临床快速筛查的目的 因该工具是一个主观评估工具, 使用者要接受专门培训, 作为常规营养筛查工具并不实用 3.2 营养不良通用筛查工具 (MUST) 是由英国肠外肠内营养协会多学科营养 2
