Application of the GLIM criteria in patients with intestinal insufficiency and intestinal failure at nutritional risk on admission.

GLIM criteria showed a higher malnutrition rate than ESPEN criteria. The incidence of malnutrition diagnosed by FFMI was higher than other phenotypic criteria such as BMI, ASMI and SMI among patients with intestinal insufficiency and intestinal failure. The FFMI threshold needs to be combined with different situations to develop different recommendations.
