Data from the ERA-EDTA Registry were examined for trends in excess mortality in European adults on kidney replacement therapy

The objective of this study was to investigate whether the improvement in survival seen in patients on kidney replacement therapy reflects the enhanced survival of the general population. Patient and general population statistics were obtained from the European Renal Association-European Dialysis and Transplant Association (ERA-EDTA) Registry and the World Health Organization databases, respectively. Relative survival models were composed to examine trends over time in all-cause and cause-specific excess mortality, stratified by age and modality of kidney replacement therapy, and adjusted for sex, primary kidney disease and country. In total, 280,075 adult patients started kidney replacement therapy between 2002 and 2015. The excess mortality risk in these patients decreased by 16% per five years (relative excess mortality risk (RER) 0.84; 95% confidence interval 0.83-0.84). This reflected a 14% risk reduction in dialysis patients (RER 0.86; 0.85-0.86), and a 16% increase in kidney transplant recipients (RER 1.16; 1.07-1.26). Patients on dialysis showed a decrease in excess mortality risk of 28% per five years for atheromatous cardiovascular disease as the cause of death (RER 0.72; 0.70-0.74), 10% for non-atheromatous cardiovascular disease (RER 0.90; 0.88-0.92) and 10% for infections (RER 0.90; 0.87-0.92). Kidney transplant recipients showed stable excess mortality risks for most causes of death, although it did worsen in some subgroups. Thus, the increase in survival in patients on kidney replacement therapy is not only due to enhanced survival in the general population, but also due to improved survival in the patient population, primarily in dialysis patients.Peer reviewe

Access to kidney transplantation in European adults aged 75–84 years and related outcomes:an analysis of the European Renal Association–European Dialysis and Transplant Association Registry

To access publisher's full text version of this article click on the hyperlink belowTo what extent access to, and allocation of kidney transplants and survival outcomes in patients aged ≥75 years have changed over time in Europe is unclear. We included patients aged ≥75-84 years (termed older adults) receiving renal replacement therapy in thirteen European countries between 2005 and 2014. Country differences and time trends in access to, and allocation of kidney transplants were examined. Survival outcomes were determined by Cox regression analyses. Between 2005 and 2014, 1392 older adult patients received 1406 transplants. Access to kidney transplantation varied from ~0% (Slovenia, Greece and Denmark) to ~4% (Norway and various Spanish regions) of all older adult dialysis patients, and overall increased from 0.3% (2005) to 0.9% (2014). Allocation of kidney transplants to older adults overall increased from 0.8% (2005) to 3.2% (2014). Seven-year unadjusted patient and graft survival probabilities were 49.1% (95% confidence interval, 95% CI: 43.6; 54.4) and 41.7% (95% CI: 36.5; 46.8), respectively, with a temporal trend towards improved survival outcomes. In conclusion, in the European dialysis population aged ≥75-84 years access to kidney transplantation is low, and allocation of kidney transplants remains a rare event. Though both are increasing with time and vary considerably between countries. The trend towards improved survival outcomes is encouraging. This information can aid informed decision-making regarding treatment options.European Renal Association-European Dialysis and Transplant Association (ERA-EDTA

REIN : un outil au service des patients

International audienceOn the occasion of the 20th anniversary of the REIN (French Renal Epidemiology and Information Network), a summary work on the contributions of the national French ESKD register was carried out. On the issue of patients’ perspectives, the following key messages were retained. As shown by the SONG (Standardised Outcomes in Nephrology) initiative, the criteria for judging the dialysis treatment that patients and care-givers prefer are not those that are traditionally found in published studies. For example, for haemodialysis, they are fatigue, ability to travel, time without dialysis, impact on family and ability to work. The concern to give the patients a voice has been at the heart of the REIN registry right from the outset. In addition, there are patient representatives in the REIN Scientific Council and the Steering Group. Although mainly focused on quantitative health data collected from professionals, REIN has also supported studies pertaining to data collected directly from patients. These studies enable addressing questions pertaining to the problems faced by patients in their care pathway and their life with the disease. The setting up of a tool for routine and electronic collection of the patients’ point of view in the evaluation of their treatment and the support of patient-initiated research contribute to positioning the REIN as a partner tool at the service of patients, unique in FranceÀ l’occasion des 20 ans du REIN (Réseau Epidémiologie et Information en Néphrologie), un travail de synthèse sur les apports du registre a été mené. Sur le point de vue des patients avec une maladie rénale stade 5, les messages clés suivants ont été retenus.L’initiative SONG (Standardised Outcomes in Nephrology) l’a montré, les critères de jugement de la prise en charge en dialyse que les patients et aidants privilégient ne sont pas ceux que l’on retrouve traditionnellement dans les études publiées. Par exemple, en hémodialyse, il s’agit de : la fatigue, la capacité à voyager, le temps sans dialyse, l’impact sur la famille et la capacité à travailler.La préoccupation de donner la parole aux patients a d’emblée été au cœur du registre REIN. En outre, des représentants de patients siègent au conseil scientifique REIN et au sein du groupe de pilotage.Bien qu’essentiellement orienté sur des données de santé quantitatives recueillies auprès des professionnels, REIN a également soutenu les études portant sur des données recueillies directement auprès des patients. Ces études permettent d’aborder des questions proches des problématiques des patients sur leurs parcours de soins et leur vie avec la maladie.La mise en place d’un outil de recueil électronique et de routine du point de vue des patients dans l’évaluation de leur prise en charge et le soutien de recherches à l’initiative des patients participent à positionner le REIN comme outil partenaire au service des patients, unique en France

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

International audienceThe 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

[Epidemiology of chronic kidney disease in France.]

End-stage renal failure affects more than 50000 people in France, or nearly 1 per thousand; 60% receive dialysis and 40% have a functioning transplanted kidney. Its incidence is stable, except among those older than 75 years, in whom incidence continues to rise. In nearly half of all cases end-stage renal failure follows hypertension or diabetes, principally type 2 noninsulin-dependent diabetes. About 30% of patients begin dialysis on an emergency basis; this demonstrates the elevated frequency of inadequate predialysis management of chronic kidney disease, from any cause. Since 2002, "chronic kidney disease" has been defined as the persistence for more than 3 months of kidney damage, which is either a laboratory or histologic or morphologic abnormality or a glomerular filtration rate (GFR)<60 mL/min for 1.73 m(2) of body surface, independently of the initial cause. It is classified by stage of severity to facilitate the application of good clinical practice guidelines. Moderate or severe chronic kidney disease, defined by GFR<60 mL/min/1.73 m(2) is approximately 40 times more common than end-stage renal failure. Individuals with chronic kidney disease are much more likely to die of another disease than to progress towards with end-stage renal failure. Diabetes, hypertension, a history of cardiovascular disease, nephrectomy, recurrent urinary infections or kidney failure in the family are all factors that should result in regular check-ups for chronic kidney disease. In two thirds of those older than 70 years, the GFR estimated by laboratories according to Cockcroft and Gault's formula is between 30 and 60 mL/min, but this does not always signal the presence of chronic kidney disease

Lack of Monitoring Is Associated with Risk of Acute Kidney Events among Patients with Inflammatory Bowel Disease

Background: Although the iatrogenic risk of kidney failure is infrequent with treatment for inflammatory bowel disease (IBD), the repercussions for the patient could be major. The aim of this study was to assess the incidence of kidney events in IBD and to examine the protective effect of kidney function monitoring. Methods: In the French National Health Insurance database, 94,363 patients had a diagnosis of IBD between January 2010 and December 2016. By using a survival model with time-dependent covariates, we analyzed the time from inclusion in this IBD cohort to the first hospitalization for acute kidney impairment (AKI) according to patient characteristics, comorbidities, IBD phenotype and presence of monitoring. Results: A total of 693 patients were hospitalized for AKI, with an incidence of 1.36/1000 person&ndash;years (95% confidence interval [CI] 1.26&ndash;1.47). The incidence of AKI was lower than those without 5-aminosalicylic acid (5-ASA) use. Patients with 5-ASA use rarely had any lack of monitoring as compared with those not under 5-ASA use (3% vs. 17%). On multivariate analysis, lack of monitoring was associated with a substantial risk of AKI (hazard ratio 3.96, 95% CI [3.20&ndash;4.90], p &lt; 0.0001). Conclusions: Increased frequency of monitoring is essential to identify nephropathy at an early stage and avoid the progression to chronic kidney disease

Le recueil en routine de données de santé perçue à l’ère du paiement à la qualité : préconisations de la Commission épidémiologie et santé publique de la SFNDT

International audienceIn France, the method of financing is mainly based on the quantity of care produced. The fixed-rate financing of patients with chronic kidney disease at stage IV or V introduces the notion of payment to quality. Part of the quality assessment will focus on the patients' feelings about their care. The objective of this paper is to assess these indicators used in nephrology, markers in their own right of the quality of care. The patients reported outcomes measures considering the impact of illness or care and the Patient Reported Experience Measures considering their perception of their experience with the health care system or care pathway, are broader than quality of life. These PROs are measured using standardized and validated questionnaires, generic or specific. The Standardised Outcomes in Nephrology initiative has shown that PROs, too often neglected in favor of biological criteria, are instead favored by patients. In the context of a broad deployment of monitoring the quality of life for the purpose of evaluation of care, outside research protocol, the Commission recommends one of the following 2 tools: EuroQol 5D and 12-Item Short Form Health Survey, a compromise between feasibility and relevance and e-SATIS given its great use in health facilities, with an annual follow-up

Description of trajectories of patients with end-stage renal disease from the REIN registry

International audienceSince 2001, the aim of the REIN registry has been to identify patients suffering from end-stage renal disease and benefiting from replacement therapy in France. The analysis of trajectories aims to evaluate the flow of patients between the different types of treatment in order to better understand and predict patient pathways. The objective of this study was to analyse the incoming and outgoing flows at 1 year of patients prevalent in the REIN registry on 12/31/2017.Methods: Flow analysis was carried out on patients prevalent on 12/31/2017 in the REIN registry by studying the before and after treatment modalities on 12/31/2016 and 12/31/2018. This analysis was initially carried out on all patients, then in sub-groups for each of the 5 treatment modalities.Results: The analyses covered 85,472 patients prevalent on 12/31/2017. The overall analysis showed that more than 20% of patients had been diagnosed with end-stage renal disease the year before. Regarding inflow, there was a relative stability for patients treated with self-care hemodialysis, in-center haemodialysis, peritoneal dialysis, and graft, in contrast to patients treated with hemodialysis in a medical unit. Regarding outgoing flows, proportion of deaths at one year was 9%. Peritoneal dialysis was the modality with the highest outflow proportion at one year.Conclusion: Analysis of patients' trajectories shows variable evolution profiles according to treatment modality and thus could be a valuable tool in the evaluation and improvement of management and care in the field of end-stage renal disease.Contexte et objectifs. Le registre REIN a pour objectif, depuis 2001, de recenser les patients souffrant d’insuffisance rénale chronique terminale et bénéficiant d’un traitement de suppléance sur le territoire français. L’analyse des trajectoires vise à évaluer les flux de patients entre les différentes modalités de traitement afin de mieux connaître et prévoir leurs parcours. L’objectif de la présente étude était d’analyser les trajectoires entrantes et sortantes à 1 an des patients prévalents du registre REIN au 31 décembre 2017.Méthodes. L’analyse des trajectoires a été effectuée sur les patients prévalents au 31 décembre 2017 en étudiant la modalité de traitement antérieure au 31 décembre 2016 et la modalité ultérieure au 31 décembre 2018, puis en sous-groupe pour chacune des 5 modalités de traitement retenues.Résultats. Les analyses ont porté sur un total de 85 472 patients. Plus de 20 % des sujets présentaient une insuffisance rénale chronique terminale découverte dans l’année. On observait une relative stabilité des flux entrants dans les modalités hémodialyse en centre ou autonome, dialyse péritonéale, et greffe, contrairement à l’hémodialyse en Unité de dialyse médicalisée. Pour les flux sortants, une proportion de décès à un an de 9 % était constatée. La dialyse péritonéale était la modalité avec la proportion la plus élevée de patients sortis à 1 an.Conclusion. L’analyse des trajectoires des patients montre des profils d’évolution variables, selon les modalités de traitement, et pourrait ainsi constituer un outil précieux dans l’évaluation et l’amélioration de la prise en charge et de l’offre de soins de l’insuffisance rénale chronique terminale
