Assessment of Dietary Balance in Home-Dwelling Patients With Stage 4 and 5 Chronic Kidney Disease Using URIKI (IKI), a Connected Urine Test Strip and In Vitro Diagnostic Medical Device

The goal of this clinical trial is to evaluate whether the integration of URIKI, a connected urine test strip and in vitro diagnostic medical device, can improve the nutritional management of patients with stage 4 or 5 chronic kidney disease (CKD) living at home. The primary purpose is to assess whether URIKI can support dietary monitoring and optimize dietitians' workload through remote collection of urinary and nutrition-related data. The main question it aims to answer is: Does the integration of URIKI improve the efficiency of dietitians' work in the nutritional follow-up of patients with stage 4 or 5 chronic kidney disease? Participants will: Receive a URIKI kit at home, including a portable reader, urine test strips, and access to the My URIKI mobile application. Perform one urine measurement per day at home for 10 consecutive days using the URIKI device. Enter nutrition- and health-related information into the application, including meal photographs or descriptions, hydration information, and responses to brief questionnaires. Receive remote support for installation and use of the device if needed. Have their urinary measurements reviewed by authorized healthcare professionals. Receive a personalized dietary assessment and nutritional feedback from the hospital medical team and/or IKI dietitians through the My URIKI application. Complete patient experience questionnaires at study entry and at the end of participation. The expected duration of participation is up to 30 days. Approximately 450 patients with stage 4 or 5 chronic kidney disease will be enrolled in nephrology centers across France.
