Reasons for the dropout of peritoneal dialysis patients / 中华肾脏病杂志

ABSTRACT

Objective To explore the reasons for withdrawal from peritoneal dialysis (PD) in our hospital.Methods This was a single-center,retrospective cohort study.Patients who started PD in the Department of Nephrology,the First Affiliated Hospital of Nanchang University from November 1st,2005 to February 28th,2017,were enrolled,and followed up to May 31,2017.Patients who continued PD after May 31,2017 were as the control group.Patients who withdrew from PD were divided into 4 subgroupsdeath group,hemodialysis group,kidney transplantation group and loss of follow-up group.The clinical characters of 4 subgroups were compared with the control group.Results A total of 998 patients were enrolled with age of (49.36± 14.94) when PD started and median dialysis duration of 27.13(12.84,42.29) months,in whom 570 patients (57.11％) were male.Five hundred and seventeen dropout events were recorded,and the dropout rate was 51.80％.The main reason for withdrawal from PD was death (258 patients,49.90％),followed by hemodialysis (166patients,32.11％),kidney transplantation (66 patients,12.77％) and loss to follow-up (27 patients,5.22％).The leading cause of death was cardio-cerebro-vascular diseases (136 cases,52.71％),followed by infection (42 cases,16.28％),dyscrasia (20 cases,7.75％) and tumor (5 cases,1.94％).The main reason for transfering to hemodialysis was insufficient dialysis (76 cases,45.78％),followed by peritonitis (55 cases,33.13％) and catheter dysfunction (24 cases,14.46％).Compared with those in the control group,in the death group patients were older at PD commencement,and had higher proportions of hypertension,diabetes and cardio-cerebro-vascular diseases (all P ＜ 0.05).The proportions of male and diabetes mellitus were higher in the hemodialysis group than those in the control group (both P ＜0.05).Biochemical indicators showed that serum albumin and blood phosphorus were lower in the death group than those in the control group (both P ＜ 0.05);blood albumin was significantly lower in the hemodialysis group than that in the control group (P ＜ 0.05).Conclusions The main reasons for withdrawal from PD in our center are death and transfering to hemodialysis.The cardio-cerebro-vascular disease is the leading cause of death,and inadequate dialysis is the main reason for transfering to hemodialysis.
