ABSTRACT
Background: Home dialysis therapies such as peritoneal dialysis (PD) and home hemodialysis (HHD) are beneficial for quality of life and patient empowerment. The short technique survival time partly explains their low prevalence. We aimed to assess the risk of transfer to facility-based hemodialysis in patients treated with autonomous PD, assisted PD and HHD. Methods: This was a retrospective study using data from the REIN registry of patients starting home dialysis in France from 2002 to 2019. The risks of transfer to facility-based hemodialysis (HD) were compared between three modalities of home dialysis (HHD, nurse-assisted PD, autonomous PD) using survival models with a propensity score (PS)-matched and unmatched cohort of patients. Results: The study included 17 909 patients: 628 in the HHD group, 10 214 in the autonomous PD group, and 7067 in the assisted PD group. During the follow-up period, there were 5347 transfers to facility-based HD. The observed number of transfers was 2458 (13.7%) at 1 year and 5069 (28.3) at 5 years after the start of home dialysis, including 3272 (32%) on autonomous PD, 1648 (23.3%) on assisted PD, and 149 (23.7) on HHD. Owing to clinical characteristics differences, only 38% of HHD patients could be matched to patients from the others group. In the PS-matched cohort, the adjusted Cox model showed no difference in the risk of transfer for assisted PD (cs-HR 1.04, 95% CI 0.75-1.44) or HHD (cs-HR 1.07, 95% CI 0.77-1.48) compared with autonomous PD. Conclusions: Unlike results from other countries, where nurse assistance is not fully available for PD-associated care, there was no difference in technique survival between autonomous PD, nurse-assisted PD, and HHD in France. This discrepancy may be attributed to our inclusion of a broader spectrum of patients who derive significant benefits from assisted PD.
ABSTRACT
Introduction: We have launched a pilot study, called DIADIDEAL, to propose nurse-assistance at home for arterio-venous fistula (AVF) cannulation in home hemodialysis (HHD) patients. The aim of the present study was to describe enrollment of the patients and their nurses. Materials: All prevalent HD patients on 30th November 2018 with no medical contraindication to HDD treatment and all incident patients on dialysis from the 30th November 2018 to the 21st April 2023 were eligible. Results: Among 155 prevalent HD patients, 4 patients were included. Among the 276 incident patients on dialysis during the study period, 6 were included. We have phoned 23 nurse centers during the recruitment period. Eight of them agreed to learn in our unit how to cannulate AVF; 27 private nurses were enrolled. Discussion: The results of the DIADIDEAL study will be available in 2024; we hope it will lead to a reimbursement of nurse-AVF cannulation at home in HDD.
Introduction: L'étude DIADIDEAL est une étude pilote sur la ponction de fistule artério-veineuse (FAV) assistée par infirmier libéral en hémodialyse à domicile (HDD). L'objectif de l'étude actuelle est de rapporter le recrutement des patients et de leurs infirmiers diplômés d'État libéraux (IDEL). Matériels et méthodes: Tous les patients prévalents en HD au 30 novembre 2018 n'ayant pas de contre-indication médicale à un traitement par HDD ainsi que tous les patients incidents en dialyse du 30 novembre 2018 au 21 avril 2023 étaient éligibles. Résultats: Parmi les 155 patients prévalents en hémodialyse, 4 ont été inclus. Parmi les 276 patients incidents en dialyse sur la période, 6 ont été inclus dans l'étude. Parmi les 23 cabinets IDEL contactés pour l'étude, 8 ont accepté et 27 IDEL ont été formés à la ponction de FAV. Discussion: Les résultats de l'étude DIADIDEAL seront disponibles en 2024 et viseront à obtenir une nomenclature pour l'acte de ponction de FAV par les IDEL.

BACKGROUND: Social deprivation is associated with lower peritoneal dialysis (PD) uptake. This study was carried out to evaluate the role of social deprivation on the outcome of PD. METHODS: This was a retrospective study of data extracted from the Renal Epidemiology and Information Network registry for patients older than 18 years who started PD in metropolitan France between 1 January 2017 and 30 June 2018. The end of the observation period was 31 December 2020. The exposure was the European Deprivation Index calculated using the patient's address. The events of interest were death, transfer to haemodialysis (HD), transplantation and the composite event of death or transfer to HD. A Cox model and Fine and Gray model were used for the analysis. RESULTS: A total of 1581 patients were included, of whom 418 (26.5%) belonged to Quintile 5 of the European Deprivation Index (the most deprived patients). In the Cox model, the most deprived subjects did not have a greater risk of death (cause-specific hazard ratio (cs-HR): 0.76 [95% confidence interval (CI): 0.53-1.10], transfer to HD (cs-HR 1.37 [95% CI: 0.95-1.98]) or the composite event of death or transfer to HD (cs-HR: 1.08 [95% CI: 0.84-1.38]) or a lower risk of kidney transplantation (cs-HR: 0.73 [95% CI: 0.48-1.10]). In the competing risk analysis, the most deprived subjects had a higher risk of transfer to HD (subdistribution hazard ratio (sd-HR): 1.54 [95% CI: 1.08-2.19]) and lower access to kidney transplantation (sd-HR: 0.68 [0.46-0.99]). CONCLUSION: In PD patients, social deprivation was not associated with death or the composite event of death or transfer to HD. Socially deprived individuals had a greater risk of transfer to HD and lower access to kidney transplantation in the competing risk analysis.
ABSTRACT
BACKGROUND: In the last two decades, sex and gender differences have been documented in chronic kidney disease (CKD) management, including access to renal replacement therapy and its outcomes. The objectives of this study were to 1) compare the pre-dialysis healthcare utilization in men and women, and 2) examine the sex-specific factors associated with emergency dialysis start. METHODS: Adult patients with CKD who started dialysis in France in 2015 were extracted from the Renal Epidemiology and Information Network registry. Patients were matched to the French National Health Data System database to extract healthcare utilization data for the 2 years before dialysis start. Frequencies and monthly rates of consultations and hospitalizations were compared between men and women. Logistic regression analyses were performed separately in the two groups. RESULTS: Among the 8856 patients included, 3161 (35.7%) were women. Median age (71 years) and estimated glomerular filtration rate (8.1 and 7.7 ml/min for men and women) were similar between groups at dialysis start. Monthly consultations rates with a general practitioner and nephrology-related care were similar between women and men. Some sex-specific differences were found: higher frequencies of consultations with a psychiatrist in women and more frequent hospitalizations for circulatory system diseases in men. Emergency dialysis start rate was 30% in both groups. Emergency dialysis start was associated with acute nephropathy, compared with slowly progressive nephropathy, in women but not in men (OR = 1.48, p<0.01 vs 1.15, p = 0.18). CONCLUSIONS: This study found similar quantitative pre-dialysis healthcare utilization in men and women. To better understand sex/gender differences in CKD care trajectories, future research should focus on patients with CKD who are unknown to nephrology services, on patients receiving conservative care and on the sex/gender-specific mechanisms underlying care decision-making.

Background: This study was carried out to evaluate the association between patient sex and the proportion of nurse-assisted peritoneal dialysis (PD) at dialysis initiation and to explore whether sex disparities in nurse-assisted PD utilization was explained by predialysis care and/or by social deprivation using mediation analysis. Methods: This was a retrospective study using data from the Renal Epidemiology and Information Network (REIN) registry linked to the French National Healthcare Database (SNDS) of incident patients between 1 January 2017 and 30 June 2018. A regression logistic was used for statistical analysis. A mediation analysis explored the direct effect of sex on nurse-assisted PD proportion and the indirect effect through the European Deprivation Index (EDI), and the number of general practitioner (GP) and nephrologist visits before dialysis initiation. Results: Among 1706 patients on PD, there were 637 women (37.3%) and 1069 men (62.7%). Nurse-assisted PD proportion was 332/610 (54.4%) for women vs 464/1036 (44.8%) for men. In the multivariable analysis women were more likely to be treated by nurse-assisted PD {odds ratio (OR) 1.92 [95% confidence interval (CI) 1.46-2.52]}. Nurse-assisted PD was associated with the median number of GP visits [OR 1.44 (95% CI 1.11-1.86)] and with the median number of nephrologist visits [OR 0.59 (95% CI 0.46-0.76)]. The mediation analysis showed a direct effect of sex on nurse-assisted PD [OR 1.90 (95% CI 1.80-2.01)] and an indirect effect through the median number of GP visits [OR 1.05 (95% CI 1.04-1.06], the median number of nephrologist visits [OR 1.02 (95% CI 1.02-1.03)] and quintile 5 of the EDI [OR 1.03 (95% CI 1.02-1.03)]. Conclusion: Women were more frequently treated by nurse-assisted PD than men. Differences between women and men in predialysis care and social deprivation could explain the greater utilization of nurse-assisted PD among women.
ABSTRACT
BACKGROUND: Cat ownership is common in peritoneal dialysis (PD) patients, even with recent guidelines recommending avoiding domestic animals during PD exchanges to limit the risk of peritonitis due to pet contamination. We analysed the outcomes of patients who experienced cat-related peritonitis compared with those who experienced peritonitis due to other causes. METHODS: This retrospective study based on the Registre de Dialyse Peritoneale de Langue Française data analysed the outcomes of 52 patients experiencing cat-related peritonitis from the beginning of the database (1986) until 21 June 2022 compared with those of 208 matched patients experiencing peritonitis due to other causes. A Cox regression model examined the association between cat-related peritonitis and the composite end point of death in PD or transfer to haemodialysis (HD), death in PD and transfer to HD. RESULTS: Among patients with an episode of cat-related peritonitis, 11 (21.1%) died, 19 (36.5%) were transferred to HD and 11 (21.1%) were transplanted. In the group with other causes of peritonitis, these numbers were 67 (32%), 81 (39%) and 26 (12.5%), respectively. In multivariate survival analysis, age (hazard ratio (HR): 1.39; 95% confidence interval (CI): 1.13-1.70) and use of assisted PD (HR: 4.07; 95% CI: 2.11-7.86) were associated with the risk of death. Having experienced cat-related peritonitis was not significantly associated with any of the three outcomes (death, transfer to HD or PD cessation). CONCLUSIONS: Patients on PD should be aware that cats may cause a peritoneal infection, which results in similar consequences to those of other causes of peritonitis. However, pets at home should not be considered a contraindication to PD.
ABSTRACT
On 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 ESKD incidence, the following key messages were retained. Thanks to several studies conducted using data from the REIN registry, the spatial variations of incidence of stage 5 chronic kidney disease in the replacement stage could be explained, in part, by the health condition of the general population as well as by the socio-economic context and differences in practices. Just like what is observed in other countries, the incidence is stabilising, or even decreasing, especially among people who do not have diabetes. Thanks to the registry having provided an indicator on the initiation of the dialysis, a decrease in the rate of initiation of emergency dialysis (i.e., initiated less than 24 hours after a nephrology evaluation considering a vital risk for the patient) has been observed, resulting from an effort to understand and better anticipate the starting of the replacement.
À 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 la question de l'incidence de la maladie rénale chronique stade 5, les messages clés suivants ont été retenus. Grâce à plusieurs études menées à partir des données du registre REIN, les variations spatiales d'incidence de la maladie rénale chronique stade 5 au stade de la suppléance ont pu être expliquées, en partie, par l'état de santé de la population générale mais aussi par le contexte socioéconomique et des différences de pratiques. À l'image de ce qui est observé dans d'autres pays, l'incidence est en voie de stabilisation, voire à la baisse, en particulier chez les personnes non diabétiques. Grâce à la mise à disposition par le registre d'un indicateur sur l'initiation de la dialyse, on observe une diminution du taux d'initiation de la dialyse en urgence (c'est-à-dire initiée moins de 24 heures après une évaluation néphrologique considérant un risque vital pour le patient) résultant d'un effort pour comprendre et mieux anticiper le démarrage de la suppléance. L'initiation de la dialyse sur cathéter, autre indicateur de la prise en charge, n'a pour l'instant pas diminué mais avec la mise en place du forfait MRC en octobre 2019 et à distance de la pandémie, la préparation à l'épuration extrarénale devrait être mieux anticipée.

On 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 France.
À l'occasion des 20 ans du REIN (Réseau Épidémiologie 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 coeur 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.

On 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 paediatric CKD patients, the following key messages were retained. Paediatric stage 5 chronic kidney disease (CKD) has particularities that require to be analysed and taken into account because the mortality of these patients remains 30 times higher than that of children of the same age. The REIN registry enables illustrating the specificities of stage 5 CKD in the paediatric age-group in France and providing a set of indicators making it possible to describe the future of these patients as well as the choices made concerning the modalities of replacement therapy. As compared to other European countries, the incidence and prevalence of stage 5 CKD in France is in the middle range for children under 15 and 20 years old. Renal transplant is by far the leading treatment for stage 5 CKD in children and adolescents under 18 years of age in France, allowing to offer these patients the best possible life expectancy. Owing to the small volume of patients, only a nationwide registry can provide an unbiased view and enables analysing this population requiring a hyperspecialised treatment. The participation of French paediatric nephrologists in the REIN French registry also enables providing input to the European registry (ESPN/ERA www.espn-reg.org/index.jsp) and the international registry (IPNA https://ipna-registry.org) (Consulted on September 15th 2022) and thus the possibility of international studies, which are vital to be in line with an approach to improving practices.
À 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 la question des patients pédiatriques, les messages clés suivants ont été retenus. La maladie rénale chronique (MRC) stade 5 pédiatrique a des particularités qui nécessitent d'être analysées et prises en compte car la mortalité de ces patients reste 30 fois supérieure à celle des enfants du même âge. Le registre REIN permet d'illustrer les spécificités de la MRC stade 5 à l'âge pédiatrique en France et de fournir un ensemble d'indicateurs permettant de décrire le devenir de ces patients ainsi que les choix faits concernant les modalités de traitement de suppléance. En comparaison à d'autres pays européens, l'incidence et la prévalence de la MRC stade 5 en France se situent dans les valeurs moyennes chez les enfants de moins de 15 et 20 ans. La transplantation rénale est de loin le premier traitement de la MRC stade 5 parmi les enfants et les adolescents de moins de 18 ans en France, permettant d'offrir à ces patients la meilleure espérance de vie possible. En raison du petit volume de patients, seul un registre à l'échelon national permet d'avoir une vision non biaisée et d'analyser cette population nécessitant une prise en charge hyperspécialisée. La participation des néphropédiatres français au registre français REIN permet aussi d'alimenter le registre européen (ESPN/ ERA www.espn-reg.org/index.jsp) et le registre international (IPNA https://ipna-registry.org) (Consulté le 15 septembre 2022) et ainsi la possibilité d'études internationales, indispensables pour s'inscrire dans une démarche d'amélioration des pratiques.

On 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 elderly CKD patients, the following key messages were retained. The population of elderly dialysis patients continues to grow. These patients have multiple comorbidities including pathologies specific to the elderly like undernutrition, walking and cognitive disorders. The data from the REIN registry has been the subject of numerous studies pertaining to this group showing heterogeneous prognosis and treatment, requiring to be better evaluated to target an individualised treatment. Decision support tools have been developed using the registry data to help nephrologists and patients in deciding whether to start replacement therapy and whether to refer elderly patients for assessment for a renal transplant. Finally, the risk-benefit evaluation of the different replacement therapies in this population should be monitored at the registry level and on a case-by-case basis in clinical practice.
À 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 la question des patients âgées, les messages clés suivants ont été retenus. La population des patients âgés en dialyse ne cesse de croître. Ces patients ont de multiples comorbidités dont des pathologies spécifiques aux personnes âgées comme la dénutrition, les troubles de la marche et de la cognition. Les données du registre REIN ont fait l'objet de nombreuses études portant sur ce groupe montrant un pronostic et une prise en charge hétérogènes, nécessitant d'être mieux évalués pour cibler une prise en charge individualisée. Des outils d'aide à la décision ont été développés à l'aide des données du registre pour aider les néphrologues et les patients dans la décision de démarrer ou non un traitement de suppléance et d'orienter ou non les patients âgés vers un bilan d'évaluation en vue d'une transplantation rénale. Enfin, l'évaluation du bénéficerisque des différents traitements de suppléance dans cette population doit être poursuivie à l'échelle du registre et au cas par cas en pratique clinique.

On 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 its role in research, the following key messages were retained. The growing number of publications, dissertations, theses and teams involved shows that the REIN registry has attained its objective of being a shared research infrastructure, in the field of epidemiology as well as in public health, health economics or medical data processing. REIN is a valuable tool for the study of specific kidney diseases, particularly for epidemiological data pertaining to rare diseases that may lead to stage 5 of a chronic kidney disease. The linkage with the data from the National Healthcare Data System enables integrating and analysing the medical treatments received by patients, before the initiation of the replacement therapy and towards the end, as well as the details of the hospital stays.
À l'occasion des 20 ans du REIN (Réseau Épidémiologie et Information en Néphrologie), un travail de synthèse sur les apports du registre a été mené. Sur la question de REIN comme outil au service de la recherche, les messages clés suivants ont été retenus. Le nombre croissant de publications, mémoires, thèses et d'équipes impliqués dans la valorisation des données démontre que le registre REIN a atteint son objectif d'être une infrastructure de recherche partagée, aussi bien dans le champ de l'épidémiologie que de la santé publique, que de l'économie de la santé ou l'informatique médicale. REIN est un outil précieux pour l'étude de pathologies rénales spécifiques, en particulier pour les données épidémiologiques de maladies rares pouvant conduire au stade 5 d'une maladie rénale chronique. Le couplage avec les données du Système national des données de santé (SNDS) permet d'intégrer et d'analyser les traitements médicaux reçus par les patients, en amont de l'initiation du traitement de suppléance et au décours, ainsi que le détail des séjours hospitaliers.

On 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 its link with health authorities, the following key messages were retained. One of the purposes of REIN is to contribute to a better understanding about patient management and its evolution, and thus to be called upon to develop health strategies aimed at improving the prevention and treatment of chronic renal failure. Indeed, the planning of the supply and the evaluation of the treatment are important issues for the public health decision-makers who must have the relevant indicators and tools to help them in their decision-making and follow-up processes. REIN is clearly identified as a source of information by institutional partners, as is shown by the various requests made by the Regional health agencies (ARS), the French National Authority for Health (HAS) and the General Directorate for Healthcare Services (DGOS), as well as other health authorities. It allows estimating the needs of the population within the framework of decree nos. 2002-1197 and 2002-1198 of September 2002 relating to the treatment of chronic renal failure by renal dialysis. The recent possibility of probabilistic matching of REIN data with the data from the National Healthcare Data System (SNDS) for a pseudonymised individual allows for more detailed studies on the different care pathways, as well as evaluating the impact of the different actions or experiments that are set up, with the help of detailed clinical information from the REIN and, among other things, the expenses reimbursed by the Health Insurance.
À 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 la question de ses liens avec les administrations sanitaires, les messages clés suivants ont été retenus. Une des finalités de REIN est de contribuer à mieux connaître la prise en charge des patients et de ses évolutions et ainsi être sollicité pour l'élaboration de stratégies sanitaires visant à améliorer la prévention et la prise en charge de l'insuffisance rénale chronique. En effet, la planification de l'offre et l'évaluation de la prise en charge sont des enjeux importants pour les décideurs en santé publique qui doivent disposer d'indicateurs et d'outils pertinents pour les aider dans leur décision avec leur suivi. REIN est clairement identifié comme source d'information par les partenaires institutionnels comme en témoignent les diverses sollicitations faites par les agences régionales de santé (ARS), la Haute Autorité de santé (HAS) ou la Direction générale de l'offre de soins (DGOS) mais également d'autres administrations sanitaires. Il permet d'estimer les besoins de la population dans le cadre des décrets nos 2002-1197 et 2002-1198 septembre 2002 relatifs au traitement de l'insuffisance rénale chronique par la pratique de l'épuration extrarénale. La récente possibilité d'appariement probabiliste des données de REIN aux données du Système national des données de santé (SNDS) pour un même individu pseudonymisé permet des études plus fines sur les différents parcours de soins, mais aussi d'évaluer l'impact des différentes actions ou expérimentations mises en place, avec l'aide des informations cliniques détaillées du REIN et, entre autres, les dépenses remboursées par l'Assurance maladie.

On 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 its role in vigilance, the following key messages were retained. The vigilance system consists, among other things, of collecting information that is useful for the surveillance of health products that are drugs for pharmacovigilance, and medical devices for materiovigilance. This includes the reporting of adverse events by health professionals and manufacturers as well as the use of any information concerning the risk of adverse events. Vigilance enables improving and optimising product and patient safety by reducing the risks of adverse events and better understanding the risks and benefits. Using data from the REIN registry, cross-referenced with other external sources, it is possible to conduct post-marketing studies of these products. These studies generate hypotheses, are low-cost and are yet to be confirmed by randomised studies. Following the presentation of a study suggesting an unfavourable role of citrate dialysates on mortality, and thanks to the mobilisation of all the operators of the network, the REIN registry was able to conduct a study in a few months that made it possible to conclude that the use of citric acid in dialysates does not present a risk of excess mortality for the patients. With this example, the REIN registry has shown its adaptability and utility as a vigilance tool.
À 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 la question de son rôle dans la vigilance, les messages clés suivants ont été retenus. Le système de vigilance consiste, entre autres, à recueillir des informations utiles à la surveillance des produits de santé que sont, pour la pharmacovigilance, les médicaments et, pour la matériovigilance, les dispositifs médicaux. Cela inclut le signalement d'évènements indésirables par les professionnels de santé et les industriels mais aussi l'exploitation de toute information concernant le risque d'évènements indésirables. La vigilance permet d'améliorer et d'optimiser la sécurité du patient et des produits en réduisant les risques d'évènements indésirables et de mieux appréhender les bénéfices-risques. À l'aide de données du registre REIN, croisées avec d'autres sources externes, il est possible de mener des études après la mise sur le marché de ces produits. Ces études génèrent des hypothèses, sont de faible coût et restent à confirmer par des études randomisées. Suite à la présentation d'une étude suggérant un rôle défavorable des dialysats au citrate sur la mortalité, et grâce à la mobilisation de tous les acteurs du réseau, le registre REIN a pu mener une étude en quelques mois qui a permis de conclure que l'utilisation de l'acide citrique dans les dialysats ne présente pas de risque de surmortalité pour les patients. Par cet exemple, le registre REIN a montré sa capacité d'adaptation et son utilité comme outil au service de la vigilance.

Over the course of their disease, patients with chronic kidney disease (CKD) will be treated by several kidney replacement therapy (KRT) modalities. The transitions between KRT modalities can be experienced as traumatic by patients, and are associated with an increased morbidity and mortality, notably when they are not anticipated. Planning these transition phases could reduce the psychological trauma induced by the transfer, as well as reduce the risk of morbidity and mortality. However, the lack of a clear definition of a transfer, and the lack of criteria enabling the identification of patients at risk of transfer, prevents the anticipation of these transition phases at high risk for patients. We here discuss the various possible causes and risk factors of transfer from peritoneal dialysis (PD) to hemodialysis as well as transfer from hemodialysis to PD. The dialysis Commission of the Société francophone de néphrologie, dialyse et transplantation (SFNDT) makes some proposals to improve transition phases, such as the identification of patients at risk, specific PD programs for unplanned PD start, transition unit and hybrid therapy.
Dans le parcours de soins du patient insuffisant rénal chronique, les différentes modalités de suppléance rénale vont se succéder dans le temps créant ainsi des phases de transition. Ces phases de transition peuvent être vécues comme traumatisantes par les patients, et sont associées à une augmentation de la morbi-mortalité, particulièrement lorsqu'elles ne sont pas suffisamment anticipées. La planification de ces phases de transition par l'équipe de dialyse devrait permettre de diminuer l'expérience du traumatisme psychologique induit par le changement et de réduire le risque de sur-morbi-mortalité. Cependant, l'absence de définition standardisée de la phase de transition entre modalités, le manque de critères et d'outils identifiant les patients à risque de transfert et l'absence d'infrastructures dédiées à ces patients transitionnels sont autant de facteurs limitant l'anticipation de ces phases de transition. Nous abordons ici les différentes causes et possibles facteurs de risque du transfert de la dialyse péritonéale (DP) vers l'hémodialyse ainsi que du transfert de l'hémodialyse vers la DP. Dans cette mise au point, la Commission de dialyse de la Société francophone de néphrologie, dialyse et transplantation (SFNDT) émet certaines propositions pour améliorer la définition et la prise en charge de ces phases de transition, et propose des outils d'identification des sujets « transitionnels ¼ ainsi que des exemples structurels de programmes soutenant la transition, tels que le démarrage en urgence de la DP, l'unité transitionnelle et la dialyse hybride.

INTRODUCTION: Different techniques of guidewire exchange of tunneled catheters for hemodialysis (HD) have been reported. This study was carried out to assess the feasibility of a new procedure in chronic HD patients who needed catheter exchange because of mechanical dysfunction. METHODS: The guidewire exchange method was based on the creation of a new exit site and a new subcutaneous tunnel while using the same venous insertion site. This was a retrospective study of exchanged tunneled catheters because of mechanical complications in patients on chronic HD between June 1, 2015, and December 31, 2019. The feasibility of the procedure was defined by successful exchange and catheter patency at 6 months. Catheter survival and immediate complications were reported. RESULTS: A total of 49 procedures were performed in 34 HD patients. There was no catheter insertion failure. At 6 months, 6 catheters have lost their patency because of a mechanical complication. Thus, the success rate of the procedure was 43/49 (87.8%). Catheter survival censored on death, transplantation, or vascular access creation was 97.8% at 90 days, 86.2% at 180 days, and 74.5% at 1 year. The median catheter survival was 10.2 months. Among the 49 procedures, there were 9 hematomas at the insertion site that did not require surgical intervention. Discussion/Conlusion: Our study shows that guidewire exchange of a tunneled HD catheter by creating a new exit site and a new subcutaneous tunnel by using the same venous access is a newer method in chronic HD patients. This procedure should not be used in patients with coagulation issues. Additional studies are needed to compare the different methods of HD catheter exchange.

Thanks to the progress of dialysis, survival of patients with end-stage renal disease is increasing. For those patients who cannot benefit from a kidney transplantation, several dialysis alternatives exist, but the transition between dialysis techniques may be difficult. Home dialysis offers many advantages but requires personal commitment from the patients and the caregivers. How can we ensure smooth transitioning to the best dialysis technique at the right time for the right person? One of the main caveats of peritoneal dialysis is its limited technique survival, however, it combines the advantages of preserving residual kidney function, avoiding the need for a vascular access, or preserving it, when present, while providing good cost-effectiveness. On the other hand, home hemodialysis has excellent long-term technique survival. The home integrated model of peritoneal dialysis followed by home hemodialysis has been described as the ideal pathway of care. Eventually, in-center hemodialysis can be provided according to several schedules to adapt to the needs of the patients. The issue of technique survival and the possible need to switch to another technique should be part of the initial discussion, when the patient needs to choose the first dialysis modality. Unplanned transfers are associated with poor outcomes and unwanted shifts to in-center hemodialysis. Therefore, transfers from home-based techniques should be anticipated as much as possible in order to establish a shared decision modality process and to choose the desired new modality. Dialysis units dedicated to "transition care" should answer the needs of patients and smooth the transition process between dialysis modalities.

INTRODUCTION: Switch from hemodialysis (HD) to peritoneal dialysis (PD) is unfrequent, but incentive strategies to perform PD can lead to an increase of these transitions. However, data on transitioning from HD to PD are scarce. We hypothesized that time spent on HD before transfer to PD would impact PD outcomes. METHODS: This registry-based, nationwide study analyzed patients transferred from HD to PD. Patients who began HD between January 2008 and December 2016 were included. Cox and Fine and Gray regression models were used to explore the relationship between time spent on HD before PD and outcomes in PD: PD cessation for death or retransfer to HD (composite endpoint); for death; and for retransfer to HD. RESULTS: Over the study period, 1,985 of the 77,587 HD starters (3%) were transferred to PD. The median time spent on HD before transfer to PD was 1.94 months (interquartile range [IQR] 1.02-4.01). The median survival time on PD after this transition was 20 months (IQR 18-21). Time spent on HD before PD was associated with increased risk of death or retransfer to HD (cause-specific hazard ratio [cs-HR] 1.01, 95% confidence interval [CI]: 1-1.02 for a 1-month increase) and death (cs-HR 1.02, 95% CI: 1.01-1.03) but not with retransfer to HD censored on death (cs-HR 1.00, 95% CI: 0.99-1.01). The results were similar when considering competing events. DISCUSSION/CONCLUSION: Switch from HD to PD is rare in France. Time spent on HD before transfer is associated with patient survival but not with retransfer to HD.
