Beslenme riskini değerlendirmek ve dahili yoğun bakım ünitesi mortalitesini öngörmek için NRS-2002 ve mNUTRIC skorlarının karşılaştırılması: Prospektif gözlemsel bir çalışma

Aim: The intensive care unit (ICU) treats patients with diverse diagnoses, yet no gold-standard tool exists to assess nutritional risk and predict mortality. The American Society for Parenteral and Enteral Nutrition (ASPEN) recommend the use of the Nutritional Risk Screening-2002 (NRS-2002) and the modified Nutrition Risk in the Critically Ill score (mNUTRIC). This study aimed to determine nutritional risk using these tools and compare their performance in predicting ICU mortality.Methods: This cross-sectional study included 201 patients aged ≥18 years treated in the Medical ICU of Adana City Training and Research Hospital between April and October 2022. Patients were classified as survivors or non-survivors and followed until discharge or death. Nutritional risk was assessed using NRS-2002 and mNUTRIC, and their predictive performance for mortality was evaluated using receiver operating characteristic (ROC) analysis.Results: Among 201 patients (57.7% male, mean age 63.06±17.52 years), nutritional risk was identified in 81.6% by NRS-2002 and 25.9% by mNUTRIC. The ICU mortality rate was 45.8% (n=92). Non-survivors had significantly higher median NRS-2002 [4.5 (2–7)] and mNUTRIC [5 (1–9)] scores compared with survivors (p5 for mNUTRIC.Conclusion: Both NRS-2002 and mNUTRIC identified patients at nutritional risk and predicted ICU mortality. The mNUTRIC score demonstrated superior predictive accuracy. Cutoff values of ≥4 for NRS-2002 and ≥5 for mNUTRIC may serve as useful predictors of ICU mortality.
