The goal of this clinical trial is to evaluate the value of a smart application named "Weiyin Health" in the follow-up management of patients undergoing peritoneal dialysis. The main questions it aims to answer are:
Can the use of a smart application reduce the unplanned readmission rate?
Can the use of a smart application reduce the incidence of peritonitis?
Researchers will compare patients who use the smart application for follow-up with those who receive conventional follow-up.
Eligible patients on peritoneal dialysis will be randomly assigned to one of two groups: one group will receive conventional follow-up (WeChat group + telephone reminders), and the other group will use the "Weiyin Health" smart application for follow-up (including data collection, AI-based Q\&A, follow-up reminders, and risk alerts). Both groups will attend peritoneal dialysis specialty clinic visits once every 3 months for routine check-ups over a 12-month period.
