营养风险对慢性肾脏病患者预后的影响

对127例慢性肾脏病（CKD）患者进行营养风险筛查（NRS-2002），按有无营养风险分为2组，比较两组人院2周内的营养支持状况，以及住院时间、住院费用和死亡率。18．1％的CKD患者存在营养风险，CKD早、中、晚期的营养风险率分别为8．2％、9．4％、44．1％。营养风险组平均住院时间中位数为12．5d，无营养风险组为5．2d；住院费用中位数：营养风险组为11806元，无营养风险组为5311元，两组比较差异均有统计学意义（均P=0．00）；有营养风险组的营养支持率仅为17．4％。CKD疾病的进展可增加患者的营养风险，营养风险增加住院时间和住院费用。

To explore the effects of nutritional risks on clinical outcomes [length of stay (LOS),hospitalization expense & mortality] in chronic kidney disease (CKD) patients.A total of 127 CKD patients completed the screening of nutritional risks by Nutritional Risk Screening 2002 (NRS-2002) within 24-48 hours of admission.The data of nutritional supports within 2 weeks of admission,LOS,hospitalization expense and mortality were collected.① Among them,the prevalence of nutritional risks was 18.1％.And the values were 8.2％,9.4％ and 44.1％ in early,middle and advanced CKD groups respectively; ② LOS and hospitalization expense in nutritional risk group were significantly more than the non-nutritional risk group (12.5 d vs.5.2 d,P =0.00 ; 11 806 vs.5311 yuan,P =0.00).There was a positive correlation between NRS score and LOS or hospitalization expense; ③ The nutritional support rate of nutritional risk group was only 17.4％.The progression of CKD increased the nutritional risks leading to greater LOS and hospitalization expense.We should pay more attention to the nutritional risk screening and nutritional intervention in moderate-advanced CKD patients.
