Malnutrition is a common and serious complication in patients with chronic kidney disease (CKD), significantly impacting morbidity, mortality, and health-related quality of life. Recognizing the close association between nutritional status and clinical outcomes, recent clinical practice guidelines have emphasized proactive nutritional assessment and individualized intervention as key components of CKD management. Accurate nutritional assessment remains challenging in CKD patients due to fluid shifts, altered body composition, and laboratory variability. While various nutritional assessment tools are available, their interpretation requires careful consideration due to each tool’s characteristics and patient’s CKD stage. Nutritional interventions must be tailored to the patient’s CKD stage, dialysis status, and comorbidity profile. Strategies include individualized dietary counseling and oral nutritional supplements. Also, patient education and multidisciplinary collaboration—particularly involving nephrologists and renal dietitians—are essential to improving adherence and long-term outcomes. This review focuses on evaluating the nutritional status and intervention of CKD patients, highlighting key aspects based on the latest literature and clinical guidelines.

The Korean Society of Critical Care Nephrology, in collaboration with the Korean Society of Nephrology, has published a Clinical Practice Guideline (CPG) for Continuous Kidney Replacement Therapy (CKRT). This guideline was developed with the goal of improving patient outcomes and reducing complications, based on the latest research related to the application and prescription of CKRT. The development of this guideline involved multidisciplinary participation from leading experts in nephrology and critical care medicine, with methodological support for the guideline development process. This CPG consists of recommendations addressing 17 key questions related to the initiation of CKRT, dose, modality, dialysate, ultrafiltration, anticoagulation, application in special situations, and multidisciplinary care. Each recommendation begins with a statement graded by the strength of the recommendation and the quality of the supporting evidence, followed by a rationale that supports the recommendation. We hope that this CPG will offer practical guidance in clinical settings and contribute to the improvement of patient outcomes.
