Materials and methods: A retrospective study was designed to validate the NRS 2002, NUTRIC, and mNUTRIC when applied to SAP patients. It is essential to evaluate the prognostic performance of these nutritional risk screening tools. The Nutritional Risk Screening 2002 (NRS 2002), the Nutrition Risk in Critically Ill (NUTRIC) score and modified Nutrition Risk in Critically Ill (mNUTRIC) are nutritional risk screening tools of critically ill patients and have not been validated in patients with SAP. For SAP patients, malnutrition increases susceptibility to infection and mortality. AP patients are categorized as mild, moderately severe, and severe AP (SAP).
