Renal replacement therapy in Europe: a summary of the 2011 ERA-EDTA Registry Annual Report.

BACKGROUND: This article provides a summary of the 2011 ERA-EDTA Registry Annual Report (available at www.era-edta-reg.org).
METHODS: Data on renal replacement therapy (RRT) for end-stage renal disease (ESRD) from national and regional renal registries in 30 countries in Europe and bordering the Mediterranean Sea were used. From 27 registries, individual patient data were received, whereas 17 registries contributed data in aggregated form. We present the incidence and prevalence of RRT, and renal transplant rates in 2011. In addition, survival probabilities and expected remaining lifetimes were calculated for those registries providing individual patient data.
RESULTS: The overall unadjusted incidence rate of RRT in 2011 among all registries reporting to the ERA-EDTA Registry was 117 per million population (pmp) (n = 71.631). Incidence rates varied from 24 pmp in Ukraine to 238 pmp in Turkey. The overall unadjusted prevalence of RRT for ESRD on 31 December 2011 was 692 pmp (n = 425 824). The highest prevalence was reported by Portugal (1662 pmp) and the lowest by Ukraine (131 pmp). Among all registries, a total of 22 814 renal transplantations were performed (37 pmp). The highest overall transplant rate was reported from Spain, Cantabria (81 pmp), whereas the highest rate of living donor transplants was reported from Turkey (39 pmp). For patients who started RRT between 2002 and 2006, the unadjusted 5-year patient survival on RRT was 46.8% [95% confidence interval (CI) 46.6-47.0], and on dialysis 39.3% (95% CI 39.2-39.4). The unadjusted 5-year patient survival after the first renal transplantation performed between 2002 and 2006 was 86.7% (95% CI 86.2-87.2) for kidneys from deceased donors and 94.3% (95% CI 93.6-95.0) for kidneys from living donors.

Introduction

This summary of the 2011 ERA–EDTA (European Renal Association–European Dialysis and Transplant Association) Registry Annual Report includes data on renal replacement therapy (RRT) for end-stage renal disease (ESRD) using 44 data sets from national and regional renal registries in 30 countries in Europe and those bordering the Mediterranean Sea (Figure 1). Data sets with individual patient data were received from 27 national and regional registries in 15 countries, whereas 17 national registries from 17 countries contributed data in aggregated form.

B&H: Bosnia and Herzegovina; FYROM: Former Yugoslav Republic of Macedonia; ME: Montenegro. The incidence data for Czech Republic, Slovakia and Turkey represent dialysis patients only.

The analyses on incidence and prevalence and also on transplant rates were based on data from countries and regions that provided individual patient data or aggregated data, while the survival analysis and the calculation of expected remaining lifetimes were solely based on individual patient records. More detailed data than those presented in the current paper were published in the full 2011 ERA–EDTA Registry Annual Report [1], which is available online at www.era-edta-reg.org.

The incidence of RRT for ESRD

In 2011, a total number of 71 631 patients started RRT for ESRD among all registries reporting to the ERA–EDTA Registry. The total population covered by these registries was 615 million, resulting in an unadjusted incidence rate of 117 per million population (pmp). The highest unadjusted incidence rates were reported from Turkey (238 pmp), Portugal (226 pmp) and Greece (203 pmp), whereas the lowest unadjusted incidence rates were reported from Ukraine (24 pmp), Montenegro (26 pmp) and Russia (43 pmp). The incidence rate standardized for the EU27 population was also highest in Turkey (334 pmp). The mean age at the start of RRT was 63.4 years for countries or regions providing individual patient data and 60.0 years for countries providing aggregated data. There was a wide variation in the mean age at the start of RRT across countries, ranging from 47.9 years in Albania to 69.5 years in the Dutch-speaking part of Belgium. In registries providing individual patient data, the percentage of patients of 65 years and older at the start of RRT was 54%, ranging from 34% in Spain, Cantabria to 70% in Belgium (Dutch-speaking part) (Figure 2).

Fig. 2.

Incidence of RRT pmp at Day 1 in 2011, unadjusted (black bars) and standardized to the age and gender distribution of the EU27 population (grey bars). In addition, mean and median age (years) and percentage of patients aged 65 years and older at RRT initiation are presented. Included are data from renal registries providing individual patient data (left panel) and aggregated data (right panel). The incidence data for Czech Republic, Slovakia and Turkey represent dialysis patients only.

Table 1 summarizes the unadjusted incidence rate of RRT per million age-related population (pmarp) at Day 1 by age group. Particularly in the oldest age category of 75 years and older at the start of RRT, there was a huge variation in incidence rates, ranging from 191 pmarp in Finland to 907 pmarp in the Dutch-speaking part of Belgium.

We performed a separate analysis for children treated with RRT based on data from a selection of registries. As the numbers of children starting RRT were low, we present the incidence for the years 2010 and 2011 combined (Table 2). A more detailed overview of paediatric RRT data in Europe can be found at www.espn-reg.org.

Tables 3 and 4 present the incidence of the different treatment modalities including haemodialysis (HD), peritoneal dialysis (PD) and (pre-emptive) renal transplantation at Day 91 after the start of RRT. Whereas the incidence rates of HD were highest in Turkey (194 pmp), Portugal (187 pmp) and Greece (170 pmp), the incidence rates of PD were highest in Sweden (34 pmp), Iceland (31 pmp) and Denmark (30 pmp). For patients living with a functioning graft at Day 91 of RRT, the highest incidence rates were observed in Norway (15 pmp) and the Netherlands, Spain, Catalonia and Iceland (for all 13 pmp).

The prevalence of RRT for ESRD

On 31 December 2011, there were 425 824 RRT patients in all registries reporting to the ERA–EDTA Registry, corresponding to a prevalence of 692 pmp. As shown in Figure 3, the unadjusted prevalence of RRT pmp was highest in Portugal (1662 pmp), Belgium (French-speaking) (1271 pmp) and Spain, Catalonia (1203 pmp). On the other hand, Ukraine (131 pmp) and Russia (196 pmp) reported the lowest unadjusted prevalence. The prevalence of RRT standardized for the EU27 population was highest in Turkey (1335 pmp). On 31 December 2011, the overall mean age was 59.8 years among countries providing individual patient data and 56.9 years among countries providing aggregated data. The mean age ranged from 47.0 years in Albania to 65.4 years in Portugal. The mean percentage of prevalent patients aged 65 years and older in registries providing individual patient data was 41%, with a range from 30% in Serbia to 54% in Belgium (Dutch-speaking part) (Figure 3).

In addition, mean and median age (years) are presented. Included are data from renal registries providing individual patient data (left panel) and aggregated data (right panel). The prevalence data for Czech Republic, Israel and Slovakia represent dialysis patients only. In Romania, the prevalence of RRT is underestimated by ∼3%, due to an estimated 30% underreporting of patients living with a functioning graft.

Table 5 summarizes the unadjusted prevalence of RRT pmarp at 31 December 2011 by age group. Like for the incidence, the most pronounced variation in prevalence was observed in the highest age category (≥75 years), ranging from 918 pmp in Serbia to 4112 pmp in Dutch-speaking Belgium. The prevalence for the age group 0–19 years, averaged for 2010 and 2011, is presented in Table 6.

Renal transplants performed

The overall number of renal transplants performed in 2011 among all registries reporting to the ERA–EDTA Registry was 22 814 (37 pmp). Of those, a total of 16 118 (26 pmp) renal transplants were performed using deceased donor kidneys, 6 059 (9.9 pmp) using a living donor kidneys and for 637 (1.0 pmp) transplants the donor type was unknown. Tables 9 and 10 report that the highest overall transplant rates were reported from Spain, Cantabria (81 pmp) and Spain, Catalonia (77 pmp). Rates of living donor kidney transplants were highest in Turkey (39 pmp), Iceland (35 pmp), the Netherlands and UK, Northern Ireland (both 26 pmp).

Patient and graft survival

Survival analysis was performed using the data from 22 registries in 12 countries that provided individual patient records for the period from 2002 to 2009. The results of the unadjusted and adjusted survival analyses for all countries combined for all patients and for those aged 65 years and older are presented in Figure 4 and Table 11. The adjusted analyses for the total group of patients used fixed values for age, gender and distribution of primary renal disease, while the adjusted analyses in the group of patients ≥65 years were not adjusted for age. A more detailed description of the methods used for the survival analyses can be found in the Appendix.

aThese analyses were based on data from Austria, Belgium (Dutch-speaking), Belgium (French-speaking), Denmark, Finland, Greece, Iceland, Italy (Calabria), Norway, Spain (Andalusia), Spain (Asturias), Spain (Basque Country), Spain (Cantabria), Spain (Catalonia), Spain (Valencian region), Sweden, the Netherlands, UK (England/Wales) and UK (Scotland).

bThese analyses were based on data from Austria, Belgium (Dutch-speaking), Belgium (French-speaking), Denmark, Finland, Greece, Iceland, Italy (Calabria), Norway, Spain (Andalusia), Spain (Asturias), Spain (Basque Country), Spain (Cantabria), Spain (Castile-La Mancha), Spain (Catalonia), Spain (Extremadura), Spain (Valencian region), Sweden, the Netherlands, UK (England/Wales), UK (Northern Ireland) and UK (Scotland).

For the calculation of the expected remaining lifetimes, we used data from 18 national and regional renal registries in 11 countries that provided individual patient records for the period from 2000 to 2011. As is illustrated in Figure 5, the expected remaining lifetime for patients on RRT is much lower than for the general population. Particularly, the expected remaining lifetime of dialysis patients is strongly reduced when compared with that of transplant recipients, and it represents approximately one-third of the expected remaining lifetime of the general population. In addition to the RRT modality, age plays an important role: with a higher age, the reduction in expected remaining lifetime is less pronounced. In other words, the younger a patient the greater the reduction in expected remaining lifetime.
