ObjectiveTo conduct nutritional risk screening on patients with chronic kidney disease (CKD) using Nutritional Risk Screening 2002 (NRS2002), to understand nutritional state of CKD inpatients and the relationship between NRS2002 score and other nutrition-related indicators, so as to guide the clinic to conduct early nutrition intervention, and improve prognosis on patients. MethodsNRS2002 nutritional risk screening was performed on CKD inpatients within 1 week of admission. The patients were divided into normal nutrition group and nutritional risk group according to the NRS2002 score. The general conditions were compared between the two groups. The hemoglobin (Hb), lymphocyte counts, renal function (blood creatinine, urea nitrogen, uric acid, 24h urinary protein), total protein, albumin (ALB), blood lipids, electrolytes levels etc. were detected and compared between the two groups. The relationship between NRS2002 score and other nutrition-related indicators of the patients was analyzed. ResultsAmong the 197 CKD inpatients received nutritional risk screening, there were 53 cases (26.9%) with nutritional risk. BMI, Hb, total cholesterol, high density lipoprotein cholesterol, low density lipoprotein cholesterol, blood sodium, blood phosphorus, urea, and glomerular filtration rate (eGFR) levels in the nutritional risk group were significantly lower than those in the normal nutrition group, with statistically significant differences (P＜0.05). Pearson correlation analysis results showed that the NRS2002 scores of patients was negatively correlated with BMI, Hb, and eGFR levels, while positively correlated with blood sodium level; the albumin (ALB) level in patients was negatively correlated with eGFR level. ConclusionsThe NRS2002 score can comprehensively reflect the nutritional risk of CKD inpatients, and provide an important basis for early nutritional intervention, and it has important clinical significance for improving the prognosis of patients.
