Comparative Study of Prognosis and QOL Between APD-RPM and CAPD

Comparative Study of Automated Peritoneal Dialysis With Remote Patient Management And Continuous Ambulatory Peritoneal Dialysis on the Prognosis and QOL in Peritoneal Dialysis Patients

This is an observational, multicenter, parallel control study, planning to enroll 750 eligible patients to receive automated peritoneal dialysis with remote patient management (APD-RPM) and continuous ambulatory peritoneal dialysis (CAPD). Patients will attend follow-up every 12 ± 1 weeks for a total of 156 weeks. This study aims to compare the effects of APD-RPM and CAPD treatment on the prognosis and quality of life.

This is an observational study based on the real-word diagnosis and treatments. Target subject population include end-stage renal disease patients (aged 18-75 years) with peritoneal dialysis 3 months and longer. Standard peritoneal balance test of eligible patients should be rapid peritoneal solute transfer rate (4-hour D/P creatinine value > 0.65). Patients will be divided into two groups to receive standard APD-RPM or CAPD with a ratio of 1:2.

Peritoneal dialysis in APD-RPM group (n=250): (1) APD mode is recommended but not limited to continuous circulating peritoneal dialysis (CCPD); (2) Dialysis dose ranges from 5 to 10 liters per day and depends on previous APD prescription and dialysis adequacy; (3) Glucose concentration starts from low concentration (1.5%) and depends on previous dialysis prescription.

Peritoneal dialysis in CAPD group (n=500): (1) Dialysis dose ranges from 5 to 10 liters per day at the run-in period. For those with regular peritoneal dialysis, the original dose can be used according to the volume status and solute clearance effect in the past 3 months; (2) Exchange time and abdominal retention time is generally 2-5 times and 1 time at daytime and night, separately; (3) Glucose concentration includes 1.5%, 2.5% or 4.25%; (4) The treatments can be adjusted according to the change of residual renal function, peritoneal transport characteristics, volume status, solute clearance, clinical status and peritonitis.
