Objective. To compare the survival of patients with chronic kidney disease (CKD) on hemodialysis (HD) versus peritoneal dialysis (PD). Materials and methods. Survival analysis of a retrospective cohort of patients ≥ 18 years who started HD versus PD at the Victor Lazarte Echegaray Hospital from 2015 to 2019. We analyzed the following covariates: age, sex, diabetes mellitus as cause of CKD, temporary central venous catheter (CVC) as initial vascular access and glomerular filtration rate. Survival was calculated with Kaplan-Meier curves for the overall cohort and for age ≥ 60 years, diabetes mellitus as a cause of CKD and CVC. The risk of death was estimated by Hazard Ratio (HR) according to the Cox proportional hazards model for each covariate adjusted for dialysis type in a bivariate and multivariate analysis considering significant difference if the p-value < 0.05. Results. We included 368 patients on HD of whom 129 (35.1%) died, and 172 patients on PD of whom 66 (38.4%) died (p=0.455). The cumulative probability of survival at 60 months for HD was 30% and for PD was 37% with similar survival curves (p=0.719). The median survival time for HD was 32 months (IQR: 20-53) and for PD was 32.5 months (IQR: 18-57) (p=0.999). The covariates associated with higher mortality adjusted for dialysis type were age ≥60 years (HR 1.77; p<0.001) and diabetes mellitus as a cause of CKD (HR 1.63; p=0.002). Conclusions. Survival of patients with CKD on HD and PD was similar.
