Peritoneal Dialysis (PD) is an established renal replacement treatment technique with decreasing mortality rates in recent years and minimal long-term overall survival. There is limited information available on the survival trend of the technique over time and differences in certain groups.
This was a retrospective cohort study in which electronic records of patients discharged from the PD program between January 2020 and June 2023 were analyzed. Survival of the technique was defined using the criteria of death, transfer to hemodialysis (HD), and loss of property rights.
La mediana de edad fue 62 años (rango: 49,7-70). La principal etiología fue la diabetes mellitus en 88 pacientes (72,1%). Durante el período de estudio, ocurrieron 87 eventos de muerte, y el 9% ocurrió en la modalidad de diálisis peritoneal ambulatoria continua (DPCA) (7 de 47 pacientes). La supervivencia global de la técnica fue de 26,7 meses (rango: 10,55-62,08), mayor en DPA (32 meses, rango: 11,36-65,82) que en CAPD (21,7 meses, rango: 7,89-55,93). Otras causas no identificadas se registraron como principal causa de muerte en 49 casos (40,2%), seguidas de neumonía en 19 casos (15,6%) y COVID-19 en 10 casos
We identified a survival rate for the technique similar to that reported in the literature but below international recommendations. The transition to HD was mainly related to infectious and mechanical causes. The main causes of death were bacterial pneumonia, SARS-CoV-2 pneumonia, and other unidentified causes.
