Peritoneal Dialysis in Italy: the 8th GSDP-SIN census 2022

Objectives. The results are reported here of the 8th National Census (Cs-22) of Peritoneal Dialysis in Italy, carried out in 2022-23 by the Italian Society of Nephrology's Peritoneal Dialysis Project Group and relating to 2022. Methods. The Census was conducted in the 227 non pediatric centers which performed Peritoneal Dialysis (PD) in 2022. The results have been compared with the previous Censuses carried out since 2005. Results. Incidence: in 2022, 1350 patients (CAPD=52.1%) started on PD (1st treatment for ESRD). PD was started incrementally by 35.3% in 136 Centers. The catheter was placed exclusively by a Nephrologist in 17.0% of known cases. Prevalence: there were 4152 (CAPD=43.4%) patients on PD on 31/12/2022, with 21.1% of prevalent patients on assisted PD (family member caregiver: 86.3%). Out: in 2022 the PD drop-out rate (ep/100 pt-yrs) was: 11.7 to HD; 10.1 death, down; 7.5 Tx. The main cause of transfer to HD remains peritonitis (23.5%), although its reduction over the years is confirmed (Cs-05: 37.9%). Peritonitis/EPS: the incidence of peritonitis in 2022 was 0.176 ep/pt-yr (696 episodes). The incidence of new cases of EPS fell in 2021-22 (7 cases). Other results: the number of Centers using 3.86% for the peritoneal equilibration test (PET) (57.7%) increased. PD for heart failure continues to be used in 44 Centers (66 pts). Conclusions. Cs-22 confirms PD's good results in Italy.

[Peritoneal Dialysis in Italy: the 6th GSDP-SIN census 2016]

OBJECTIVES

We report here the results of the 6th National Census (Cs-16) of Peritoneal Dialysis in Italy, carried out in 2017-18 by the Italian Society of Nephrology's Peritoneal Dialysis Study Group and relating to 2016.

METHODS

The Census was conducted using an on-line questionnaire administered to the 237 non pediatric centers which did perform Peritoneal Dialysis (PD) in 2016. The results have been compared with the previous Censuses carried out since 2005.

RESULTS

Incidence: In 2016, 1,595 patients (CAPD=56.1%) started on PD (1st treatment for ESRD) and 4,607 on hemodialysis (HD). PD was started incrementally by 32.5% in 144 Centers. 15.6% were late referrals, and 5.1% began within 48-72 hours of insertion. The catheter was positioned exclusively by a Nephrologist in 24.3% of cases. Prevalence: Patients on PD on 31/12/2016 were 4,607 (CAPD=46.6%), with 22.2% of prevalent patients on assisted PD (family member caregiver: 80.5%). Out: In 2016, PD dropout rate (ep/100 pt-yrs: 12.5 to HD; 11.8 death; 7.0 Tx) has not changed. The main cause of transfer to HD remains peritonitis (23.8%), although it is still decreasing (Cs-05: 37.9%). Peritonitis/EPS: The incidence of peritonitis in 2016 was 0.211 ep/pt-yr (939 episodes). The incidence of new cases of EPS in 2015-16 is diminishing too (16 cases=0.176 ep/100 pt-yrs). Other results: In 2016 the number of Centers using 3.86% for the peritoneal equilibration test (PET) (49.8%) increased, and the Centers carrying out home visits diminished (51.5%).

CONCLUSIONS

Cs-16 confirms that PD in Italy is having good results.
