Self-Management Data and Disease Progression in Chronic Kidney Disease

This study evaluates disease progression and management characteristics in patients with chronic kidney disease (CKD) using an integrated mobile application and hospital information system (HIS) clinical data. The main goals of this study are: 1. To observe patient self-management recording performance and adherence (continuity of recording blood pressure, blood glucose, medication, and diet). 2. To explore associations between integrated self-management data and disease progression or acute exacerbations (e.g., acute kidney injury, hyperkalemia). 3. To gather foundational evidence for optimizing and improving future digital health applications for CKD management. Participants will be recruited from outpatient clinics at Chungnam National University Hospital and followed prospectively for 1 year with regular follow-up visits.
