The essential of 2012 results from the French Renal Epidemiology and Information Network (REIN) ESRD registry

Abstract

The French Renal Epidemiology and Information Network (REIN) registry began in 2002 to provide a tool for public health decision support, evaluation and research related to renal replacement therapies (RRT) for end-stage renal disease (ESRD). It is relying on a network of nephrologists, epidemiologists, patients and public health representatives. Continuous registration covers all dialysis and transplanted patients. In 2012, in France, 10,048 patients started a RRT (154 per million inhabitants). Elders provided majority of new patients (median age at RRT start: 70 years old). New patients had a high and age increasing rate of comorbidities, especially diabetes (42% of the new patients) and cardiovascular comorbidities (>50% of the new patients). Like previous years, incidence is stabilized. On December 31, 2012, 73,491 patients were receiving a RRT in France (1127 per million inhabitants, 56% on dialysis and 44% living with a functional renal transplant). More than 50% of patients were undergoing in-center hemodialysis with significant variations among regions. An increase in medical satellite unit hemodialysis but a decrease in self-care unit hemodialysis rates were noticed across the time, whereas peritoneal dialysis remained stable at 7%. Five years after starting RRT, the overall survival rate was 51% but only 16% among patients over 85 years. Mortality rate was highly dependent on treatment and age; transplanted patients aged 60-69 had a 27/1000 patients-year mortality rate versus 133 for a dialysis patient. Patients who started dialysis had a probability of first wait-listing of 4.8% at the start of dialysis (pre-emptive registrations) and 27% at 72 months. Whatever their diabetes status was, patients older than 60 had poor access to the waiting list. Seventeen percent of the patients received a first renal transplant within 15.4 month median time; 3% had received a pre-emptive graft. Ten years after the start of the French ESRD registry, this report provides a comprehensive and nation-wide overview of dialysis and transplantation cares in France, including overseas.
