Abstract
Background: A prolonged waiting time for a kidney transplant leads to a significant decline in the general health status of many patients with chronic kidney disease (CKD). This deterioration may cause these patients to be classified as unsuitable for transplantation during the waiting period owing to frailty, poor body composition, or the development of new comorbidities. Studies have shown that physical exercise and tailored nutrition can maintain and improve physical performance and overall health status.
Methods: This study is a 1:1 controlled, randomized trial. The control group will receive standard care along with an app designed for dialysis patients, which provides information on topics such as nutrition, vital signs, blood parameters, and details about their condition. In addition, the intervention group will receive individualized nutritional and exercise recommendations, along with a 3-week inpatient rehabilitation program. At 0, 6, and 12 months, body composition (body mass index, skeletal muscle mass, body fat mass, and waist circumference) and physical performance (6-min walk test, timed up and go test, sit-to-stand test, one-legged stance test, stair climbing test, and frailty), blood values (e.g., potassium and phosphate), and quality of life (KDQOL) will be evaluated. Bone density (tibia and radius) will be measured at 0 and 12 months.
Discussion: Studies have demonstrated that physical activity and tailored nutrition have positive effects on the general health of dialysis patients. However, pretransplantation preparation programs (prehabilitation) aimed at preserving transplant eligibility have not yet been evaluated. This study aims to address this gap by investigating a potential care program for patients on the transplant waiting list.

期刊介绍：
Trials is an open access, peer-reviewed, online journal that will encompass all aspects of the performance and findings of randomized controlled trials. Trials will experiment with, and then refine, innovative approaches to improving communication about trials. We are keen to move beyond publishing traditional trial results articles (although these will be included). We believe this represents an exciting opportunity to advance the science and reporting of trials. Prior to 2006, Trials was published as Current Controlled Trials in Cardiovascular Medicine (CCTCVM). All published CCTCVM articles are available via the Trials website and citations to CCTCVM article URLs will continue to be supported.
