Patients undergoing assisted peritoneal dialysis show a better technique survival: a competing risk analysis



The aim of the study was to compare patient mortality and technique survival between patients undergoing assisted peritoneal dialysis (aPD) and self-care peritoneal dialysis (sPD).

Patients who underwent peritoneal dialysis (PD) at the dialysis center of Second Affiliated Hospital of Soochow University from January 1st, 2012 to Dec 31th, 2016, were included and followed to December 31th, 2019. Subjects were divided into  assisted peritoneal dialysis and  selfcare peritoneal dialysis  groups according to whether the patient could independently complete the peritoneal dialysis  procedure. Differences in mortality and technique failure rates were compared using competing risk analysis.

A total of 384 patients were included in this study, with 274 patients in the selfcare peritoneal dialysis group and 110 patients in the assisted peritoneal dialysis group. The multivariate competing risk regression analysis revealed that age, assisted peritoneal dialysis, diabetes, residual renal function and serum albumin level were the independent risk factors for mortality. Besides, technique failure in assisted peritoneal dialysis patients was lower than in the selfcare peritoneal dialysis group .

Conclusion: These results found that assisted peritoneal dialysis patients had higher mortality rates but lower technique failure rates than selfcare peritoneal dialysis patients. Higher mortality in assisted peritoneal dialysis is probably related to the negative selection of the more comorbid patients.
