Multimodal Prehabilitation in Frail and Non-frail Patients Waiting for a Kidney Transplantation (the FRAILMAR Study)

Frailty is very frequent among patients waiting for a kidney transplantation (KT). Frailty and poor fitness powerfully predict mortality, kidney graft survival, and healthcare utilization after KT. Frailty in patients with chronic kidney disease (CKD) displays a constellation of features that characterize a special population. Intervention is essential to improve quality of life for frail CKD patients, regardless of their age. A pre-transplant intervention including physical therapy, nutritional measures and psychological support scheduled for before the transplant may improve patient retention and compliance, better mitigate the effects of frailty and poor fitness after KT, and improve main outcomes in frail CKD patients. The main objective is to assess effectiveness, feasibility and safety of a prehabilitation program (exercise, nutritional plans, psychological advice) in frail and non-frail KT candidates on clinical and functional outcomes after KT.
