The Effect of Nutritional Interventions on Long-Term Patient Survival in Advanced Chronic Kidney Disease.

Patients with end-stage kidney disease (ESKD) are at high risk of malnutrition and subsequent related mortality when starting dialysis. However, there have been few clinical studies on the effect of nutritional interventions on long-term patient survival. A 2-year longitudinal study was conducted from January 2012 to December 2016. A total of 186 patients with non-dialysis ESKD started the nutritional education program (NEP), and 169 completed it. A total of 128 patients participated in a NEP over 6 months (personalized diet, education and oral supplementation, if needed). The control group ( = 45) underwent no specific nutritional intervention. The hospitalization rate was significantly lower for the patients with NEP (13.7%) compared with the control patients (26.7%) ( = 0.004). The mortality odds ratio for the patients who did not receive NEP was 2.883 (95% CI 0.993-8.3365, = 0.051). The multivariate analysis showed an independent association between mortality and age (OR, 1.103; 95% CI 1.041-1.169; = 0.001) and between mortality and the female sex (OR, 3.332; 95% CI 1.054-10.535; = 0.040) but not between mortality and those with NEP ( = 0.051). Individualized nutrition education has long-term positive effects on nutritional status, reduces hospital admissions and increases survival among patients with advanced CKD who are starting dialysis programs.
