Individualized intervention for frail non-dialysis elderly patients with chronic kidney disease: protocol for a randomized controlled trial

BACKGROUND: Frailty describes an age-related clinical state and can be regarded as a predictive factor for fall, disability, hospitalization, and death in the elderly. Previous studies proved that frailty could be reversed or attenuated by multi-disciplinary intervention. However, only a few studies have been performed in non-dialysis patients with chronic kidney disease. METHODS: A randomized parallel controlled trial will be conducted to compare an individualized intervention according to the consequence of the comprehensive geriatric assessment with routine treatment. A total of 242 individuals aged ≥65 years, who fulfill the Fried Phenotype of frailty and have chronic kidney disease stage 3–5 without dialysis will be recruited from the Department of Nephrology and Department of Internal Medicine, Beijing Chaoyang Hospital, Capital Medical University. The participants will be followed-up for 30 days and 12 months. DISCUSSION: This protocol would be established to examine the efficiency of targeted intervention for frailty. If a positive consequence could be obtained, a novel treatment for frail elderly patients with chronic kidney disease who have never undergone dialysis can be carried out in routine clinical practice. TRIAL REGISTRATION: The trial was prospectively registered at the Chinese Clinical Trials Registry with the registration number ChiCTR-IOR-17013429 on November 17, 2017.
