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

Abstract

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.

INTRODUCTION

The purpose of this document is to summarize with graphics ad tables the main descriptive elements obtained from the database of the Peritoneal Dialysis and Home Hemodialysis Registry (RDPLF) in metropolitan France in 2022. No discussion is intended in this report, which is primarily intended to provide background material for readers to illustrate their own work or presentations.

These tables and charts may be freely copied provided that this document is cited with its DOI.

The originals can also be obtained as PowerPoint files from the RDPLF secretariat.

COMPLETENESS

The Réseau Epidemiologie Information en Nephrologie (REIN) is comprehensive for France, it is possible to know the completeness of peritoneal dialysis (PD) patients included in the RDPLF by comparing the number of patients treated on December 31 in each database. According to the 2019 REIN report[1]97.8% of French patients were included in 2020. On January 1, 2022 the number of treated patients was identical in both registries (personal communication Cécile Couchoud and Mathilde Lassalle). The RDPLF database is structured in several modules described elsewhere [2,3]. Various tables and graphs included in this text were also obtained from the RDPLF open access statistical analysis web module[4].

DESCRIPTION OF THE POPULATION

Number of prevalent patients in 2022 (treated at least 1 day): 3955 patients

TREATMENT BEFORE PD

- non-dialysed: 3113 (80.4%)

- hemodialysed: 626 (16.2%) (of which 11 in self-dialysis and 2 in home hemodialysis)

- transplantated: 135 (3.4%)

DATA FROM THE NURSING SECTION OF THE DATA BASE

45% of RDPLF centers participate to the optional data-base module on nursing, the results below represent some of the data available in 2022

Figure 9.96,7 % des patients ont été formés après la pose du cathéter et 3,3 % avant. Parmi ceux formés après la pose du cathéter , le délais entre pose et début de formations est très variable, avec une durée médiane de 19 jours
