Background
5-year cumulative survival on HD patients is variable: 41% USRDS, 45% ERA-EDTA, 65% ANZDATA. Survival of patients on HD modality in Mexico is scarce: median survival 700 d.
Methods
We did a retrospective cohort analysis from Nov 2015-Nov 2021 on HD pts from a network of 6 facilities across Mexico. Death was registered as the interest event, time to event was expressed in days and used to estimate survival. Clinical and laboratory data were considered in a comparative analysis between groups and as explanatory variables. Survival analysis with K-M method and Cox hazards were used.
Results
Total 1165 pts included, 246 (21%) died, 919 (79%) censored. 401 (44%) were lost (facility or modality change or KTR) and 518 (56%) continue alive. 5 year cumulative survival was 73%, median survival 3463 d. Multivariate analysis showed significantly increased risk of death for KtV <1.2 (HR 1.73, IC1.16-2.58), Na <135 (1.63, 1.09-2.43), Creat <10 (1.83, 1.14-2.94), Non-tunneled VA (3.32, (1.85-5.96) and age (1.02, 1.01-1.03).
Conclusion
We report higher survival rates compared with other series, which might be partly explained by selection and survival biases; also a high proportion of patients lost to follow up. National kidney disease register is needed.
