[Renal Epidemiology and Information Network: 2006 annual report]

In 2006, 6,509 patients with end-stage renal disease living in 16 regions covering 48(M) inhabitants (79% of the French population), started renal replacement therapy (dialysis or preemptive graft): median age was 71 years; 3% had a preemptive graft. The overall crude annual incidence rate of renal replacement therapy for end-stage renal disease was 137 per million population (pmp) in 16 regions that met exhaustivity, with significant differences in sex and age-adjusted incidence across regions (107 to 179 pmh). At initiation, more than one patient out of two had at least one cardiovascular disease and 37% diabetes (88% Type 2 non-insulin-dependent diabetes). On December 31, 2006, 25,774 patients living in these 16 regions were on dialysis: median age was 69.5 years. On December 31, 19,491 patients were living with a functioning graft: median age was 53 years. The overall crude prevalence rate of dialysis was 536 pmp in 15 regions. The overall crude prevalence rate of renal graft was 409 pmp in 15 regions. The overall crude prevalence rate of renal replacement therapy for end-stage renal disease was 945 pmp in 15 regions, with significant differences in age-adjusted prevalence across regions (765 to 1061 pmh). In the 2002-06 cohort of 18,264 incident patients, the overall one-year survival rate was 82%, 72% at 2 years and 63% at 3 years. Survival decreased with age, but remained above 50% at 2 years in patients older than 75 at RRT initiation. Among the 6,321 new patients starting dialysis in 2006 in the 16 regions, 6% had a BMI lower than 18.5 kg/m(2) and 17% a BMI higher than 30. At initiation, 62% had a haemoglobin value lower than 11g/l and 9% an albumin value lower than 25g/l. The first haemodialysis was started in emergency in 30% of the patients and with a catheter in 48%. On December 31, 2006, 8% treated in the dialysis units of the 16 regions received peritoneal dialysis, of which 38% were treated with automated peritoneal dialysis. 95% of the patients on haemodialysis had 3 sessions per week, with a median duration of 4 hours. In 2006, 2,144 patients received a renal graft. On December 31, 2006, 4,838 patients were on the waiting list for a renal graft in the transplantation centres of the 16 regions.
