We present primary descriptive data in the form of tables and graphs for patients treated with home hemodialysis in France and French-speaking Belgium in 2022. These data were recorded in the database of the French-speaking Register of Peritoneal Dialysis and Home Hemodialysis (RDPLF).

The average age of the patients is similar in both countries: 52.7 years in France and 54.7 years in Belgium. The percentage of patients with diabetes is 25.6% in Belgium and 18.5% in France.

The majority of patients undergo daily hemodialysis 5 to 7 times per week.

Of the patients, 11% have received peritoneal dialysis in the past. Of these, 23.5% transitioned to home hemodialysis less than 3 months after stopping peritoneal dialysis, while 23.6% transitioned after 2 years of center-based or self-administered hemodialysis.

Practices differ between Belgium and France. In Belgium, a central catheter is used in 57.5% of cases, compared to 8.5% in France. For arteriovenous fistula puncture, the buttonhole technique is used in 91% of cases in Belgium and 47.8% of cases in France.

In Belgium, 70% of patients dialyze independently, while in France, 71% of patients dialyze in the presence of a family member.

The main cause of treatment discontinuation is transplantation (44% of technical dropout).

RDPLF annual reporthome hemodialysisdialyse quotidienneRDPLFFranceBelgiumINTRODUCTION

The aim of this document is to summarize in graphic form the main descriptive elements obtained from the database of the Register of Peritoneal Dialysis and Home Hemodialysis (RDPLF) in French-speaking Belgium (Dutch-speaking Belgium does not participate in the Home Hemodialysis Register) and France (metropolitan France and overseas departments and territories) in 2022. No discussion is planned in this report, which is intended above all to provide basic documentation for dialysis teams to illustrate their work or presentations. An identical presentation was adopted for peritoneal dialysis in our last issue [1]. The original slides can be obtained from the RDPLF secretariat.

These tables and graphs may be freely copied, provided that the present document is cited with its DOI. The originals can also be obtained as PowerPoint files from the RDPLF secretariat.

EXHAUSTIVENESS

Taking as a reference the Réseau Epidemiologie Information en Néphrologie (REIN) [2], which is exhaustive for France, the number of patients treated by home hemodialysis (HDD) and registered in the RDPLF represents around 45% of the total number of French patients treated by home hemodialysis. In comparison, 98% of peritoneal dialysis (PD) patients are included in the RDPLF. In Belgium, only French-speaking centers (Wallonia) participate in the HDD register of the RDPLF: taking the GNFB report [3] as a reference, the completeness of the RDPLF for Wallonia is 91%.

DESCRIPTION OF THE POPULATION

Number of prevalent patients in 2022 (treated at least 1 day): 573 patients (181 in Belgium and 392 in France); their profile is summarized in Table I. and Table II..

Table III. summarizes the treatment modality prior to home hemodialysis, but this does not preclude a different one prior home hemodialysis treatment. In the case of hemodialysis or transplantation, patients may have been previously treated with PD. This table should therefore be compared with the following (Table IV).

History of peritoneal dialysis before home hemodialysis

Sixty-four patients (11.7%) of the 573 patients treated by home hemodialysis in 2022 had previously been treated by peritoneal dialysis (PD). This percentage is higher than that shown in Table II, as it includes patients who have had other treatment in the meantime (in-center hemodialysis or transplantation): the way the data are entered into the system means that it is not possible to know the exact path taken by patients who have changed treatment modality several times between PD and HDD.

The duration of in-center hemodialysis and/or limited care self-dialysis treatment after cessation of peritoneal dialysis and before home hemodialysis treatment varies widely Figure 1:

- In Belgium, the patient monitors the session alone in 70% of cases.

- In France, 71% of sessions are monitored by the family.

IN-CENTER HEMODIAYSIS RESPITE

The cumulative duration of treatment in 2022 in the cohort monitored was 154361 days; the cumulative number of days of in-center respite, all causes combined, was 7889 days, i.e. 17.5 days of in-center withdrawals per patient-year of home hemodialysis treatment. The figure is identical in Belgium and France

HOME HEMODIALYSIS DISCONTINUATION

-One hundred and thirty patients discontinued home hemodialysis treatment in 2022, in the cohort monitored by the RDPLF: 48 in Belgium and 82 in France. Taking the two countries together, the breakdown of reasons for leaving the technique is summarized in Figure 3, and the causes of transfer in Figure 4.
