#3525 TRANSITION BETWEEN NUTRITION CATEGORIES IN HEMODIALYSIS PATIENTS

Abstract Background and Aims We have previously characterized four nutritional categories in hemodialysis (HD) patients, evaluated by the method of ICNDS (Integrative Clinical Nutrition Dialysis Score) slope three subsequent monthly scores. Category 1 appeared to best category 4 worst status [1]. The aim this study was explore association between at dialysis initiation, survival, Length Stay hospital (LOS), transition nutrition up 12 months following initiation. Methods Two hundred twenty-six patients who started March 2009 2019 were enrolled study. Scoring is based on 7 parameters: albumin, percentage post weight change, creatinine, urea, cholesterol, CRP, Kt/V. calculated first scores each patient HD commencement later. Cox proportional hazard model used present differences mortality ratio (HR) during year patients. analysis variance hoc Bonferroni test analyze hospitalization frequency LOS dialysis. Pearson chi-square initiation one after. Results Baseline associated all-cause HR (χ2 = 16.402, df 3, P 0.051). Patients 2,3 significantly with increased compared (category 4: 3.951, 95% CI 1.218-12.812, 0.022; 3: 2.705, 1.126-6.497, 0.026; 2: 1.778, 0.631-5.064, 0.027). affected (F 4.671, 0.003). lower 2 3 (between 4, 0.006; 0.03). Hospitalization not 1.705, 0.167). showed no after 6.763, 0.149). Conclusion a main prognostic factor, exists may prove future be patients’ survival.
