RESUMO
In patients with end-stage kidney disease (ESKD), peritoneal dialysis (PD) is increasingly being adopted in developing nations due to its cost-effectiveness and advantages as a home-based treatment. However, the survival outcomes of chronic PD patients in Mexico, where the burden of ESKD is high, remain poorly understood. This study aimed to assess the survival experience of long-term PD patients and evaluate its determinants. A single-center cohort study collected clinical and epidemiological data for long-term PD initiations between February 2013 and January 2023. The analysis, which utilized Kaplan-Meier and Cox proportional hazard regression methods, included data from 370 patients. The overall mortality rate was 4.7 per 1000 person-months, with a significant decrease in survival rates observed between months 24 and 36 post-PD initiation. Older age at PD initiation and the use of continuous ambulatory peritoneal dialysis, as compared to the automated modality, were associated with an increased risk of mortality. The study provides valuable insights into the survival outcomes of chronic PD patients in Mexico and suggests the need to optimize treatment strategies to enhance long-term prognoses for patients with ESKD. Further research is needed to better understand the factors influencing survival in this population.
