Background: The number of elderly (≥75 years) patients with end-stage renal disease (ESRD) has increased markedly, including in the Limousin region, which has the oldest population in France. We retrospectively compared outcomes in elderly and non-elderly ESRD patients who started dialysis during two time periods. Methods. Baseline clinical characteristics, care, and survival rates were assessed in 557 ESRD patients aged ≥75 and <75 years who started dialysis in 2002-2004 and 2005-2007. Survival curves and Cox proportional hazards model were used to assess survival and factors associated with survival. Results: Of the 557 patients, 343 and 214 were <75 years and ≥75 years, respectively. Dialysis was started in 2002-2004 and 2005-2007 by 197 and 146 patients <75 years, respectively, and by 96 and 118 patients ≥75 years, respectively. Median age (73.4 years [interquartile range [IQR] 61.7-79.5 years] vs 69.5 years [IQR 57.4-77.4 years] p = 0.001) and the proportion aged ≥75 years (44.7% vs 32.8%, p = 0.004) were significantly higher in 2005-2007 than in 2002-2004. Improved initial status during 2005-2007 was observed only in patients ≥75 years, with a decrease in some co-morbidities, improved walking and better preparation for dialysis. Mortality rates were significantly lower in 2005-2007 than in 2002-2004 (hazard ratio 0.81, 95% confidence interval 0.69-0.95; p = 0.008), with the difference due to factors associated with clinical status and care. Conclusions: Improved initial clinical status and better preparation for dialysis, accompanied by increased survival, were observed for patients ≥75 years who started dialysis more recently, perhaps because of early referral to a nephrologist. © 2013 Glaudet et al.; licensee BioMed Central Ltd.
