Objective:To evaluate the clinical outcomes in peritoneal dialysis(PD)patients who received standardized retraining in The First Affiliated Hospital of Zhen Jiang University,the second largest center in China.Methods: This retrospective study comprised PD patients 18 years or older at the start of PD and during survival for at least for 90 d after the first treatment at our center from January 2005 to June2014.The1,520 patients were divided into two groups according to whether they had been retrained.Group 1(952)had received specification retraining;group 2(568)had not been retrained.The differences in survival rate,technical survival rate,and complications were compared between the two groups.Results: The differences between the two groups inpatient and technical survival rates were significant(all,P=0.000),especially in the younger patients(i.e.,<65 years)(P=0.001,P=0.000,respectively).The incidences of PD-related peritonitis and hospitalization were lower in the younger patients in group 1 patients(P=0.041,P=0.009,respectively).The incidences of the exit-site(and/or tunnel)infections,cardiovascular events,cerebrovascular events,and malnutrition between the two groups were not significant different(all,P> 0.05).Conclusion: The results showed that the differences in patient and technique survival rates between the two elderly groups were not significant(P=0.058,P=0.549,respectively).But the younger PD patients who underwent retraining(group 1)had higher patient and technique survival rates than that of those who had no retraining(group 2).In younger retrained patients,the incidences of PD-related peritonitis and hospitalization were lower.The results indicated that standardized retraining plays a large role in the survival of PD patients,especially that of younger patients.
