Relationship between Nutritional Screening Tools and GLIM in Complicated IBD Requiring Surgery

Area of Science:

• Gastroenterology
• Surgical Nutrition
• Clinical Assessment

Background:

• Malnutrition identification and preoperative nutritional care are critical for Inflammatory Bowel Disease (IBD) surgery.
• No validated nutritional screening tool currently exists for IBD patients.

Purpose of the Study:

• To develop and validate a novel nutritional screening tool specifically for IBD patients undergoing surgery.
• To compare the performance of the new tool against existing nutritional screening methods.

Main Methods:

• Developed the IBD Nutritional Screening tool (NS-IBD).
• Included 62 consecutive patients scheduled for elective surgery.
• Compared NS-IBD with NRS-2002, MUST, MST, MIRT, and SaskIBD-NR, relating all to GLIM criteria.

Main Results:

• 40% of IBD patients (25/62) were malnourished according to GLIM criteria (15 Crohn's disease, 10 Ulcerative Colitis).
• The NS-IBD tool demonstrated the highest sensitivity (0.92) in detecting malnutrition compared to other tools when assessed against GLIM criteria.

Conclusions:

• Existing nutritional screening tools exhibit low sensitivity for diagnosing malnutrition in IBD patients based on current GLIM criteria.
• The developed NS-IBD tool is superior in identifying IBD surgical patients who may require nutritional assessment and preoperative intervention.
