Peritoneal Dialysis In France Research Articles

RDPLF annual report: Profile of peritoneal dialysis patients in France in 2022, synthetic raw results

We present the main descriptive data of patients treated by peritoneal dialysis in France in 2022 in the form of tables and graphs. Patients from DROM-TOM and other French-speaking countries and regions of the RDPLF will be described in a future issue in order to group together regions with similar socio-economic and climatic characteristics.
 Since the SARS-Cov2 epidemic in 2020 and the three years that followed, the number of patients treated by peritoneal dialysis in France has decreased by 6.7%, but with significant regional variations ranging from +20% to -30%.
 Vascular (23.5%) and diabetic (20.5%) nephropathies are the most numerous.
 The average age for CAPD is 70 years and 58 years for APD
 36% of patients are assisted by a nurse and 5% by a family member.
 The average waiting time for transplant patients was 20 months.
 There is a great difference in the technique of catheter placement with a catheter survival of 72% at 5 years.

Use of arteriovenous fistula in peritoneal dialysis in France (RDPLF data

There is a consensus not to systematically create arteriovenous fistula (AVF) in patients treated with peritoneal dialysis. We wanted to verify in the French Language Peritoneal Dialysis Register (RDPLF) database what the practices are in France.
 We selected patients who stopped peritoneal dialysis between December 2016 and December 2021 and who, before their peritoneal dialysis treatment, had not been treated with hemodialysis or transplant before.
 Only 5.2% of patients had an AVF during PD, and 86.7% of these did not use it. Of the patients who did not have AVF, however, 38% were transferred to hemodialysis, often with a central venous catheter.
 While it is probably important to have a predictive algorithm to avoid definitive transfers in hemodialysis with a central venous catheter when this transfer can be planned, this report confirms the pointlessness of creating a systematic vascular access in PD, particularly when there is a kidney transplant project.

Impact of assistance on peritonitis due to breach in aseptic procedure in diabetic patients: A cohort study with the RDPLF data.

Diabetic patients often have physical impairment that could lead to manipulation errors in peritoneal dialysis (PD) and touch contamination. Nurse assistance in diabetic PD patients is known to help prevent peritonitis. We made the hypothesis that this lower risk of peritonitis was observed thanks to prevention of breach in aseptic procedure. We evaluated the impact of nurse-assisted PD on specific causes of peritonitis, especially on peritonitis due to a breach in aseptic procedure. This was a retrospective observational study of the data from the French Language Peritoneal Dialysis Registry. All diabetic patients older than age 18 years starting PD in France between 1 January 2012 and 31 December 2015 were included in the study. The event of interest was the first peritonitis event due to a breach in aseptic procedure. Death, kidney transplantation and peritonitis due to another mechanism were considered as competing events. We examined the association of the covariates with all the possible outcomes using a subdistribution hazard model developed for survival analysis in the presence of competing risks. Four thousand one hundred one diabetic patients incident in PD were included in the study. At least one peritonitis event occurred in 1611 patients over the study period. A breach in aseptic procedure was reported in 441/1611 cases (27.3%): 209/575 (36.3%) in the self-care PD group, 56/217 (25.8%) in the family-assisted PD group and 176/819 (21.5%) in the nurse-assisted PD group. Both nurse and family assistance were associated with a lower risk of peritonitis due to breach in aseptic procedure in bivariate analysis. After adjustment on age, modified Charlson index, sex and diabetic nephropathy, patients treated by nurse-assisted PD (subdistribution hazard ratio (sd-HR) 0.52, 95% confidence interval (CI) 0.40-0.67) and those treated by family-assisted PD (sd-HR 0.70, 95% CI 0.51-0.95) had a lower likelihood of peritonitis due to a connection error compared to self-care PD in multivariate analysis. The modality of assistance was not associated with other causes of peritonitis in the multivariate analysis. While both nurse-assisted PD and family-assisted PD were associated with lower risk of peritonitis due to a breach in aseptic procedure compared to self-care PD in our study, the protective effect was greater with nurse assistance.

Trends in Peritoneal Dialysis Technique Survival, Death, and Transfer to Hemodialysis: A Decade of Data from the RDPLF

Introduction: There is limited information on the trends of peritoneal dialysis (PD) technique survival over time. This study aimed to estimate the effect of calendar time on technique survival, transfer to hemodialysis (HD) (and the individual causes of transfer), and patient survival. Methods: This retrospective, multicenter study, based on data from the French Language Peritoneal Dialysis Registry, analyzed 14,673 patients who initiated PD in France between January 1, 2005, and December 31, 2016. Adjusted Cox regressions with robust variance were used to examine the probability of a composite end point of either death or transfer to HD, death, and transfer to HD, accounting for the nonlinear impact of PD start time. Results: There were 10,201 (69.5%) cases of PD cessation over the study period: 5,495 (37.4%) deaths and 4,706 (32.1%) transfers to HD. The rate of PD cessation due to death or transfer to HD decreased over time (PR 0.96, 95% CI: 0.95–0.97). Compared to 2009–2010, starting PD between 2005 and 2008 or 2011 and 2016 was strongly associated with a lower rate of transfer to HD (PR 0.88, 95% CI: 0.81–0.96, and PR 0.91, 95% CI: 0.84–0.99, respectively), mostly due to a decline in the rate of infection-related transfers to HD (PR 0.96, 95% CI: 0.94–0.98). Conclusions: Rates of the composite end point of either death or transfer to HD, death, and transfer to HD have decreased in recent decades. The decline in transfers to HD rates, observed since 2011, is mainly the result of a significant decline in infection-related transfers.

Trends in assisted peritoneal dialysis over the last decade: a cohort study from the French Peritoneal Dialysis Registry.

BackgroundThere is limited information available on the use of assisted peritoneal dialysis (PD) over time and the impact of economic incentives on its utilization. The aim of this study was to describe the trends in assisted PD utilization and the type of assistance provided. We wanted to estimate if an economic incentive implemented in 2011 in France was associated with an increase in the utilization of nurse-assisted PD.MethodsThis retrospective, multicentre study, based on data from the French Language Peritoneal Dialysis Registry, analysed 11 987 patients who initiated PD in France between 1 January 2006 and 31 December 2015. Adjusted Cox regression with robust variance was used to examine the initiation of assisted PD, both nurse-assisted and family-assisted, accounting for the nonlinear impact of the PD starting time.ResultsThere were 6149 (51%) incident patients on assisted PD, 5052 (82%) on nurse-assisted PD and 1097 (18%) on family-assisted PD over the study period. In the adjusted analysis, calendar time was associated with the assisted PD rate: it declined from 2008 until 2013 before flattening out and then it increased after 2014. Nurse-assisted PD utilization increased significantly after 2012, whereas family-assisted PD utilization decreased linearly over time (prevalence ratio = 0.94, 95% confidence interval 0.92–0.97).ConclusionsThe assisted PD rate decreased until 2013, mainly because of a decline in family-assisted PD. The uptake in nurse-assisted PD observed from 2013 reflects the effect of an economic incentive adopted in late 2011 to increase PD utilization.

History of peritoneal dialysis in France

In France the first peritoneal dialysis was performed in the mid-1940s. For a long time reserved for frail subjects in whom hemodialysis appeared more dangerous, it is considered nowadays as a technique equivalent to hemodialysis, provided its indications and contraindications are respected and associated with the respect of the patient’s free choice after objective information. In particular, there is now a consensus to recognize its interest in patients waiting for transplantation, usually in order to preserve vascular access. Over the past decades French teams have played their role nationally and internationally, very often in partnership with their European neighbors, to improve the results achieved and to improve the different modalities. Since the end of the 1980s, the evaluation of practices has been made possible thanks to the participation in a specialized peritoneal dialysis registry.This article is a general review, not exhaustive, of the role played by the main French teams who succeeded one another.

Presentation and implementation of the first connected system of automated peritoneal dialysis in France

The first system of connected automated peritoneal dialysis (APD) was set up in France in the CHSF. This system allows to collect and transmit the data of APD sessions via a modem and a platform towards the medical team and permits the remote adaptation of the treatments. This implementation required a number of steps on national and regional levels. We present the functioning and the expected benefits of such a system.

Impact of Assisted Peritoneal Dialysis Modality on Outcomes: A Cohort Study of the French Language Peritoneal Dialysis Registry

Background: Patients on peritoneal dialysis (PD) can be assisted by a nurse or a family member and treated either by automated PD (APD) or continuous ambulatory PD (CAPD). The aim of this study was to evaluate the effect of PD modality and type of assistance on the risk of transfer to haemodialysis (HD) and on the peritonitis risk in assisted PD patients. Method: This was a retrospective study based on data from the French Language PD Registry. All adults starting assisted PD in France between 2006 and 2015 were included. Events of interest were transfer to HD, peritonitis and death. Cox regression models were used for statistical analysis. Results: Among the 12,144 incident patients who started PD in France during the study period, 6,167 were assisted. There were 5,060 nurse-assisted and 1,095 family-assisted PD patients. Overall, 5,171 were treated by CAPD and 996 by APD. In multivariate analysis, CAPD, compared to APD, was not associated with the risk of transfer to HD (cause specific hazard ratios [cs-HR] 0.96 [95% CI 0.84–1.09]). Patients on nurse-assisted PD had a lower risk of transfer to HD than family assisted PD patients (cs-HR 0.85 [95% CI 0.75–0.97]). Neither PD modality nor type of assistance were associated with peritonitis risk. Conclusions: In assisted PD, technique survival was not associated with PD modality. Nurse-assisted patients had a lower risk of transfer to HD than family assisted patients. Peritonitis risk was not influenced either by PD modality, or by type of assistance. Both APD and CAPD should be offered to assisted-PD patients.

Clusters of Practice in Peritoneal Dialysis in France: Data from the Catheter Section of the RDPLF.

Peritonitis is a major cause of peritoneal dialysis (PD) failure. Recommendations for the prevention of peritonitis are available, but wide variations exist in the peritonitis rate among countries and PD units. The objective of this study was to describe the different pattern of practices in France. This was a retrospective, multicenter study based on data from the French Language Peritoneal Dialysis Registry. Center practices were described and mapped. Clusters of practices were sought in a hierarchical analysis and centers belonging to the same clusters of practices were mapped. Data from 2,770 catheters placed in 64 centers in France between 1 February 2012 and 31 December 2016 were considered. A median of 34 (ranging from 5 to 133) catheters was reported in each center. Twenty-eight (43.8%) centers routinely administered a prophylactic antibiotic prior to catheter placement, and 8 (12.5%) centers applied a local prophylactic antibiotic at the exit site, as recommended by International guidelines. The presence of a PD nurse specialized in PD or PD referent nephrologist was not associated with better adherence to guidelines. Practices were heterogeneous across centers. We identified 5 clusters of centers according to practice. Geographical proximity was not associated with homogeneity in practices. Peritoneal dialysis practices are heterogeneous in France, even those that are subject to International guidelines. Studies to identify associations between center-specific practices and PD patient outcomes remain mandatory. Efforts should be made to standardize the PD standards of care in France.

Un plaidoyer pour la dialyse péritonéale

The prevalence of peritoneal dialysis in France remains one of the lowest in Europe in spite of official recommendations in 2008. Progress in peritoneal catheter placement and a good knowledge of the management of catheter complications are essential. A more frequent use of biocompatible solutions should achieve a better preservation of the peritoneal membrane. Such physiological peritoneal fluids seem to decrease morbidity and mortality. Best peritoneal dialysis indications are mainly young patients waiting for a kidney transplantation, old patients without malnutrition and patients with cardiac insufficiency. Objective and complete information dedicated to both peritoneal dialysis and hemodialysis is necessary, even for patients seen in emergency or unplanned or late referral patients. A pre-end-stage renal disease education program has to be mandatory. Non-medical obstacles, mainly financial, are still common so that economic incitations are necessary for the development of peritoneal dialysis. A university formation of nephrologists is now available.

Les freins financiers à la dialyse péritonéale

Peritoneal Dialysis (PD) has shown good result for the patients'survival and quality of life, but there is no development of PD in France. Many reasons can explain this situation, but we will focus here on financial restraint. PD has a low reimbursement rate, lower than the real cost of the technique. Furthermore, it is very difficult to find a place for PD patients when they need an hospitalization or lose their autonomy. The Pilot Committee for Kidney Disease is about to propose some solutions, but the effects may be limited as long as the difference in the reimbursement rate between PD and in center dialysis will persist.

Variability in Case Mix and Peritoneal Dialysis Selection in Fifty-Nine French Districts

In France, the use of peritoneal dialysis (PD) as the first-choice treatment varies greatly between districts, as it is already known to do between countries. Baseline clinical factors associated with choice of first modality were analyzed in 10 815 new end-stage renal disease patients in 59 districts. To describe practices at the district level, we used an agglomerative hierarchical classification, with proximity defined by a likelihood-ratio test that compared multivariate logistic regressions of the following factors: age, gender, diabetes, congestive heart failure, severe behavioral disorders, mobility, and employment. To propose a typology, each cluster of districts was described by a multivariate logistic regression. While populations starting PD in France, as elsewhere, are more likely to be young or employed, they are also more likely to be elderly or have congestive heart failure or severe behavioral disorders. Overall, 14% of patients start with PD, but this rate varies significantly across districts, from 0% to 45%. A specific combination of factors was associated with the first-choice modality in each group of districts. This study highlights the lack of consensual medical criteria for this choice and the likelihood that nonmedical factors may explain the observed differences. The high variability suggests that PD can be used in almost all clinical conditions. Accordingly, patient preference should play a more important role in the decision-making process.
