Early technique failure is a serious complication for peritoneal dialysis (PD) patients. The study aimed to examine the incidence, causes, and risk factors associated with early technique failure. This retrospective study included all incident PD patients in a hospital in Singapore from 2013 to 2017. The primary outcome was early technique failure, which was defined as transfer to hemodialysis for ≥ 30 days or death, within the first year of PD initiation. Secondary outcomes were death, technique failure due to PD infection, and death-censored technique failure. Overall, 517 patients were included in the study. Of these, 98 patients (19.0%) developed early technique failure. The common causes of early technique failure were death (41.8%) and infection (40.8%). Peripheral vascular disease was significantly associated with a higher hazard of early technique failure [hazard ratio (HR) 1.95, 95% confidence interval (CI) 1.04–3.63] and death (HR 3.75, 95% CI 1.71–8.21), whilst glomerulonephritis as a cause of end-stage kidney disease (compared with hypertension) was associated with a lower hazard of early technique failure (HR 0.38, 95% CI 0.18–0.77) and death (HR 0.08, 95% CI 0.02–0.37). Male gender was associated with early technique failure due to PD infection (HR 2.55, 95% CI 1.32–4.95). No specific factor was associated with death-censored early technique failure. Technique failure in the first year of PD initiation occurs in one-fifth of PD patients and is associated with peripheral vascular disease and cause of end-stage kidney disease.
