The Italian Registry of Dialysis and Transplantation (RIDT) has recently resumed the collection of data of patients on RRT in Italy. Data were requested to Regional Registries for the years 2011-2013 and they contributed according to their possibilities. Eighteen Regions or autonomous Provinces provided data with various degrees of completeness and this made possible to bridge the gap between the current and the previous census (referring to 2010).
Results: Incidence data were associated to a sample with a coverage of 77% of the national population (46/60 million inhabitants). Patients who started dialysis in these three years were, respectively, 168, 166 and 160 patients pmp. If we project this data to the national population is reasonable to think that 9500-10000 patients per year start the dialytic treatment.
Prevalence: The prevalence of patients on dialysis in Italy range, in the 10 years of RIDT, between 750 and 825 patients pmp. Based on this we can reasonably estimate that in Italy there are 45-49000 dialysis patients.
Incidence and prevalence vary widely in different regions.
Mortality on dialysis in Italy during the period 2011-2013 was on average 16.2 per 100 patient-years (95% CI: 16.1-16.7) with regional variation smaller than that observed in incidence and prevalence.
Conclusions: In this paper, data analysis are presented in a direct and non comparative manner. However, it provides information on the status of the RRT in Italy and the temporal consistency of the data is a proof of their validity.
Registry data were published in the official site of Italian Registry that can be reached through the website of SIN (www.sin-italy.org).
