Evolution of Physical Frailty and Patient-Reported Outcome Measures in Kidney Transplant Candidates: A Mixed-Methods Longitudinal Study Protocol

This study looks at how the physical and emotional health of people changes while they wait for a kidney transplant. Waiting for an organ can take a long time. During this period, some patients become "frail." This means they lose strength and are at a higher risk for health problems. The main goal is to follow these patients over time to better understand their needs. Researchers will use a mobile application to collect Patient-Reported Outcome Measures (PROMs) directly from patients about how they feel and their quality of life. The study will also include personal interviews to learn about the patients' experiences and any difficulties they face when using technology. The results of this study will help to: • Identify early which patients are losing strength or health. • Improve the support that nurses provide during the transplant waiting period. • Make sure that digital health tools are easy for everyone to use. In short, this work aims to help patients reach the day of their surgery in the best possible condition.
