Abstract:
OBJECTIVETo investigate the effects of interim hemodialysis (HD) on survival and clinical outcomes in patients with maintenance peritoneal dialysis (PD).
METHODSThe clinical data of 908 patients undergoing maintenance PD from January 2010 to December 2014 registered in Zhejiang Dialysis Regisration System were retrospectively analyzed. Among all PD patients, 176 cases received interim HD for less than 3 months, and then transferred to PD (transfer group) and 732 cases had initial PD (non-transfer group). The demographic parameters, biochemical data, comorbidity, details of peritonitis and transplantation were documented. Survival curves were made by the Kaplan-Meier method; univariate and multivariate analyses were performed with Cox proportional hazard regression model to identify risk factors of mortality.
RESULTSCompared with patients in transfer group, patients in non-transfer group had significantly higher serum albumin and total Kt/V levels. The survival rate was significantly higher in non-transfer group, but there was no significant difference in technique survival between two groups. After multivariable adjustment, initial dialysis modality (HR=1.60, 95% CI: 1.01~2.56), age (HR=1.07, 95% CI:1.05~1.09) and serum albumin (HR=0.96, 95% CI: 0.93~0.99) and Charslon comorbidity index (HR=2.54, 95% CI:1.63~3.94) were independent factors for long-term survival.
CONCLUSIONPatients who transfer to PD after interim HD have lower survival rate than patients who start with and are maintained on PD. HD is an independent risk factor for PD patients, therefore, patients with PD should be well informed and educated with dialysis protocols.
