Peritoneal Dialysis in Italy: the fourth GSDP-SIN census 2012

OBJECTIVE: To know PD modalities and results in Italy. METHODS: The Census was carried out by means of an on-line questionnaire in all the 224 non-pediatric public centers which performed PD in 2012. The results were compared with those of previous Censuses. RESULTS: Incidence. In 2012 PD was begun (first treatment for ESRD) by 1,433 pts (CAPD: 54.3%) and HD by 4,700 pts (%PD-incidence= Cs-12: 23.4%; Cs-10: 23.3%; Cs-08: 22.8%; Cs-05: 24.2%; p=NS), with a further increase in incremental PD (Cs-12: 28.8%; Cs-10: 22.8%; Cs-08: 18.3%; Cs-05: 11.9%; p-0.001). Prevalence. At 31/12/12 there were 4,299 patients on PD (CAPD: 46.1%) (%PD-prevalence= Cs-12: 17.1%; Cs-10: 16.6%; Cs-08: 16.7%; Cs-05:16.8%; p=NS), 24.5% of whom were on assisted PD (family members: 82.3%; paid caregivers: 12.4%; nurses: 0.7%; NH: 3.0%). Out. In 2012 there was no change in the PD drop-out rate (30.9 ep/100yrs-pt) (death: 481; transplant: 290; switch to HD: 511 pts). The main reason for transferring to HD remained peritonitis (28.2%). Peritonitis. The peritonitis rate (1,179 episodes) was 0.284 ep/yrs-pt. EPS. The incidence of new cases of EPS in 2011-12 (43 cases=0.505 ep/100yrs-pt) remained unchanged (2009-10= 0.529; 2004-08= 0.701 ep/100-yrs-pt). Other results. Compared to 2010, in 2012 the number of Centers using 3.86% for PET increased (30.8% vs 15.6%-p-0.001), while the number carrying out home visits remained unchanged (56.3 vs 59.4%). CONCLUSIONS: Cs-12 confirms the extensive use, stability and good results of PD in Italy. Incremental PD is on the increase. EPS remains a rare event.
