Introduction: To assess the modified Global Leadership Initiative on Malnutrition (mGLIM) status as a predictor of postoperative mortality and morbidity in patients undergoing Radical Cystectomy (RC).
Methods and materials: The American College of Surgeons - National Surgical Quality Improvement Program (ACS-NSQIP) dataset was used to select patients who underwent RC between the years 2011 to 2020. A positive mGLIM status includes patients with preoperative albumin levels < 3.5 g/L or patients with ≥ 10% weight loss over 6 months or BMI ≤ 21 kg/m2. We compared prolonged length of stay, mortality, major morbidity and Clavien-Dindo complications between mGLIM positive and negative patients. A multivariable logistic regression model was also performed to control for possible confounders. Furthermore, a sensitivity analysis was performed by propensity score matching.
Results: Our cohort consisted of 12,760 patients who underwent RC. The matched cohort yielded 4864 matched patients. After propensity score matching, patients with a positive mGLIM status had higher odds of prolonged length of stay (OR = 1.99, 95%CI [1.75, 2.27]), mortality (OR 1.56, 95%CI [1.08, 2.26]), major morbidity (OR = 1.69, 95%CI [1.51, 1.90]), Clavien-Dindo class I and II (OR = 1.77, 95%CI [1.58, 1.99]), and lower odds of Clavien-Dindo class III (OR = 0.72, 95%CI [0.57, 0.92]) as compared to those with a negative mGLIM status (P < .018).
Conclusion: A positive mGLIM status is associated with prolonged hospital stay, morbidity, and mortality following RC. This indicates that the mGLIM criteria could serve as an independent predictor of morbidity and mortality in an attempt to optimize patient counseling and preoperative care.
