基层医院营养风险筛查评分与营养不良等级的分析

The correlation analysis between nutritional risk screening scores and the levels of malnutrition in primary hospitals

目的 分析区级基层医院对住院患者的营养风险筛查2002(nutritional risk screening 2002,NRS 2002)评分与全球领导人发起的营养不良诊断共识(global leadership initiative on malnutrition,GLIM)标准诊断的营养不良等级的相关性。方法 回顾性选取2023年11月至2024年2月在绍兴第二医院医共体总院住院的361例营养风险筛查阳性(NRS2002评分≥3分)患者,按GLIM标准诊断患者是否存在营养不良,并对诊断为营养不良的患者进一步评定其营养不良等级(中度营养不良或重度营养不良),分析NRS2002评分与营养不良等级之间的相关性。结果 361例患者中最终诊断为无营养不良179例,中度营养不良140例,重度营养不良42例,Kendall’s tau-b系数值分析NRS2002评分和营养不良等级之间具有较强正相关性(Kendall’s tau-b>0.6,P<0.0001)。不同年龄段组别(<70岁与≥70岁)营养不良发生率差异有统计学意义(P<0.05)。不同性别组别营养不良发生率比较,差异无统计学意义(P>0.05)。结论 基层医院患者的NRS 2002评分越高,GLIM评定法诊断为营养不良的等级越高,两者具有较强的正相关关系。营养不良发生率与性别无关,但相较于年龄<70岁的人群,年龄≥70岁的人群营养不良发生率更高。

Objective To analyze the correlation between the scores obtained according to nutritional risk screening 2002(NRS 2002)and malnutrition level diagnosed according to global leadership initiative on malnutrition(GLIM)in district level primary hospital.Methods A retrospective study was conducted involving 361 patients with positive nutritional risk screening(NRS 2002 score≥3 points)admitted to General Hospital Medical Communities of Shaoxing Second Hospital from November 2023 to February 2024.The patients were diagnosed for malnutrition according to GLIM criteria,and those identified with malnutrition were further evaluated for the severity of malnutrition(moderate malnutrition or severe malnutrition).Statistical methods were employed to analyze the correlation between nutritional risk screening scores and the severity of malnutrition.Results Among 361 patients with positive nutritional risk screening,179 cases were diagnosed with no malnutrition,140 cases with moderate malnutrition,and 42 cases with severe malnutrition.Analysis using Kendall’s tau-b coefficient revealed a strong positive correlation between nutritional risk screening(NRS 2002)scores and malnutrition levels by GLIM criteria(Kendall’s tau-b>0.6,P<0.0001).The occurrence of malnutrition differed significantly between age groups(<70 years old and≥70 years old)(P<0.05),there is no statistically significant difference in the incidence of malnutrition between different gender groups(P>0.05).Conclusion There was a strong positive correlation between higher nutritional risk screening scores(according to NRS 2002)and higher levels of malnutrition(according to GLIM)in the primary hospital.The prevalence of malnutrition was not related to gender,but those aged≥70 years old had a higher prevalence of malnutrition compared to those aged<70 years old.
