Background
The aim of this study was to evaluate and compare three nutritional screening tools with the new GLIM criteria for malnutrition among definitive and elective surgery Crohn’s patients in China.
Methods
Nutritional screening tools, including the nutritional screening tool for IBD (NS-IBD), the Nutritional Risk Screening 2002 (NRS 2002), the Prognostic Nutrition Index (PNI) were applied to 212 patients with definitive and elective surgery Crohn’s patients in China. We compared the diagnostic values of these tools for malnutrition, using the new GLIM criteria for malnutrition as the ‘gold standards’.
Results
According to the new GLIM criteria for malnutrition, 81(61.79%) of the patients were diagnosed as malnutrition. With the use of NRS-2002, 140(66.10%)of the patients were found to be at high risk of malnutrition; with the use of NS-IBD, 181(85.30% )of the patients were found to be at moderate/high risk of malnutrition; and according to PNI, 94(44.0%)of the patients were found to be at moderate/high nutritional risk. The comparison of each nutritional risk tool showed sensitivity of 83.26%,85.74%,79.83%, and specificity was 62.91%,54.62%,57.34% for NRS-2002, NS-IBD and PNI, respectively. NS-IBD was best correlated with the ESPEN diagnostic criteria (К=0.388, p<0.001) compared with PNI (К=0.208, p=0.007) and NRS-2002 (К=0.744, p<0.032).The receiver operating characteristic curve of PNI had the highest area under the curve (AUC) compared with NRS 2002 and NS-IBD.
Conclusion
In the future, the combined application of GLIM criteria and two nutritional screening tools can better reflect the nutritional status for definitive and elective surgery Crohn’s patients.
