Purpose: To analyze and compare survival of patients initially treated with peritoneal dialysis (PD) or hemodialysis (HD).
Methods: We used data from the French REIN registry. We included all patients aged 18 years or more who started dialysis between 1st January 2004 and 12 December 2012 in Provence-Alpes-Côte d'Azur Region (PACA). These patients were followed up until 30 June 2014. Survival curves were generated using the Kaplan-Meier technique and tested using the log-rank test. Variables predictive of all-cause mortality were determined using Cox regression models. The propensity score was used.
Main results: Survival was similar between initial dialysis modalities: PD and HD, even after adjusting for the propensity score. But, when we exclude the patients who had switched from one technique of dialysis to another, survival was better in HD patients. According to the multivariate analysis, advanced age and the lack of walking autonomy appear to be associated with an increase in mortality in dialysis patients. But, the presence of hypertension improve the survival in this cohort.
Conclusion: The survival is similar between hemodialysis and peritoneal dialysis.
