Challenges of nutrition intervention for malnourished dialysis patients.
Malnutrition, or protein energy wasting (PEW), is prevalent in patients with chronic kidney disease stage 5 dialysis (CKD-5). One criterion of PEW strongly associated with morbidity and mortality in CKD-5 dialysis patients is the serum albumin level. Serum albumin levels have not improved over the past 10 years. Typical intervention strategies need to be reevaluated. Intradialytic parenteral nutrition (IDPN) is a form of parenteral nutrition delivered during dialysis that is a convenient and assured route of nutrition alimentation for high-nutrition-risk PEW patients who cannot improve nutrition status by oral and enteral routes. Recent qualification criteria for IDPN changes in Medicare part D have made this therapy an available option for many more of these high-nutrition-risk PEW patients. Nutrition support knowledge in clinicians is essential to administer IDPN effectively and to optimize clinical response. An improved understanding of the milieu of uremia and PEW of CKD-5, as well as the study of nutrition interventions inclusive of IDPN, will allow for effective strategies toward improved outcomes in the future.
