EP.FRI.332 Impact of Nutritional Deficit in Emergency Surgery (INDIcatES): A cohort study

Abstract Background Emergency laparotomy is associated with significant morbidity. Nutritional status an important factor that can influence outcomes, particularly in this setting where temporary gastrointestinal failure occur. This study aims to compare the performance of three nutrition risk tools predicting time without enteral nutrition. Methods A prospective cohort was conducted across two sites (NCT04696367). Patients undergoing NELA eligible procedures were invited participate. Data collected included demographics, surgical diagnosis, procedure, and outcomes. Nutrition assessed using tools: MUST score, Risk Index (NRI), Score 2002 (NRS). Results In total, 56 patients recruited whom 21 had small bowel obstruction. Median age 69 years 23 participants female. Overall, (41.8%) identified as high compared 11 (20.0%) NRS 4 (8.9%) NRI. return normal intake 10 days (IQR 7-14). 91%, 90%, 95% those low according MUST, NRS, NRI respectively for 5 or more. The median complication index score 15 0-34). There no difference duration complications seen any nutritional groups. Discussion shows emergency spend a prolonged intake. Current do not adequately stratify likelihood starvation at baseline, light findings.
