Abstract
Introduction The impact of switching to haemodialysis from peritoneal dialysis (PD) and the timing of this switch become more important to the long-term management of PD patients. We examined the following issues 1. The hazard of technique failure of PD on patient survival and the effect of the transfer to HD when compared to the patients continuing on PD and patients started on HD. 2. We investigated whether this hazard depends on the type of vascular access. Materials and Methods The study was as a retrospective single-centre cohort study. All ESRD patients who were on peritoneal dialysis at our centre between 01.01.2013 and 31.12.2022, were considered for inclusion in the study. Results During the study period, 677 patients were started on PD at our institute. In the present study, we did not find any significant difference in baseline characteristics between the patients who continued on PD and those who successfully switched to HD. The 90-day mortality after transfer to HD from PD was 20 patients (30.7%). The mortality was higher than the 90-day mortality in the matched 65 patients who were identified from the 372 patients who continued on PD. The significant risk factors for mortality identified after transfer to HD from PD were the absence of permanent of vascular access, lower ultrafiltration while on PD, lower serum albumin, and lower serum calcium. Discussion In our study, patients who continued on PD had a better survival than the patients transferred to HD. Other studies reported no difference in survival for patients staying on PD compared to patients with a successful switch to HD.
