The number of incident and prevalent patients with end stage renal disease on dialysis treatment is increasing in France and worldwide. A quarter of dialysis patients are initiating dialysis urgently through central venous catheters and the number of patients registered in the waiting list for renal transplantation before dialysis initiation is very low. This is also reflected in the very low number of pre-emptive renal transplantations. In order to reduce the number of dialysis patients, the French state has induced a national program proposing a multidisciplinary care pathway including the nephrology visits and at least one consultation with a dietitian and a specialist renal nurse in all patients with Chronic Kidney Disease stage 4 and 5. The aim of this single-center retrospective study is to evaluate the influence of the complete, partial or no participation in this program on the evolution of renal function and clinicobiological parameters in this group of patients.
