The 2006 ERA-EDTA Registry annual report: a precis

Introduction: This paper provides a summary of the 2006 European Renal Association-European Dialysis and Transplant Association (ERA-EDTA) Registry report. Methods: Data on renal replacement therapy (RRT) were available from 50 national and regional registries in 28 countries in Europe and bordering the Mediterranean Sea. Data sets with individual patient data were received from 35 registries, whereas 17 registries contributed data in aggregated form. For both types of registries we presented incidence, prevalence and transplant rates. Survival analysis and the calculation of expected remaining lifetimes were solely based on individual patient records.Results: In 2006, among all registries reporting to the ERA-EDTA Registry, the overall annual incidence rate of RRT was 118 per million population (pmp), and the prevalence was 630 pmp. Incidence rates varied from 213 pmp in Germany to 18 pmp in Ukraine. The overall incidence rate of RRT for end-stage renal disease (ESRD) started to decrease from 2004. The highest prevalence of RRT for ESRD was reported by Cantabria, Spain (1,234 pmp) and the lowest by Ukraine (73 pmp). Overall transplant rates were highest in Spain (61 pmp), whereas the highest transplant rates with living donor kidneys were reported from Iceland (26 pmp). The unadjusted 1-, 2- and 5-year survival of patients on RRT was 82.3 (95% confidence interval [95% CI], 82.0-82.5), 70.9 (95% CI, 70.7-71.2) and 47.5 (95% CI, 47.3-47.6) for the cohort 1997-2001, respectively
