A multicentre study involving 1,649 patients assessed malnutrition risk in major abdominal surgeries. The Subjective Global Assessment (SGA) identified 34.1% as malnourished, while various tools showed significant variability in assessments. The Malnutrition Universal Screening Tool (MUST) and Mini Nutrition Assessment Short Form (MNA-SF) exhibited the best diagnostic capabilities. MUST demonstrated strong construct and prognostic validity, proving to be the most accurate nutritional screening tool for postoperative patients, emphasizing its utility in surgical care.
