[Census 2004 of the Italian Renal and Dialysis Units--Piemonte, Liguria and Valle d'Aosta]. / Censimento 2004 dei Centri di Nefrologia e Dialisi italiani. Piemonte--Liguria--Valle d'Aosta.

The Italian Society of Nephrology (SIN) promoted a national survey in order to obtain detailed information from all Renal and/or Dialysis Units using the on-line questionnaire (158 items) regarding structural and technological resources, medical workforce organisation and activity features. The purposes of this initiative were to obtain regional benchmarks as references for renal units and to describe the current Italian renal network in order to plan further interventions for the next 5 years. In this paper data of the first three Italian Regions (Piemonte, Liguria and Valle d'Aosta) which completed the survey (100% of the units) are reported. Main findings in the 3 Regions. A) Epidemiology: prevalence of dialysis patients = 709, 720, 787 pmp (per million population); prevalence of transplanted patients = 325, 387, 279 pmp; incidence of dialysis patients = 166, 191, 156 pmp; gross mortality of dialysis patients = 13.7, 15.0, 13.0%; distribution of vascular access in prevalent dialysis patients: arteriovenous fistula = 74, 83, 76%, central venous catheter = 18, 12, 15%, vascular graft = 8, 5, 9%. B) Structural resources: hospital's number of beds = 49, 72, 49 pmp, dialysis places = 166, 158, 164 pmp. C) Personnel resources: renal physicians = 44, 47, 41 pmp, renal nurses = 186, 194, 205 pmp; each renal physician takes care of 16, 15, 19 dialysis patients and each renal nurse cares for 3.8, 3.7, 3.8 dialysis patients. D) Activity: admission to hospital = 1507, 2392, 1606 pmp, renal biopsies = 109, 133, 57 pmp. Despite discrepancies in population density in the three Regions, most indexes are surprisingly similar and show the satisfactory level of renal care attained in the Northwestern Italian area. Further improvements in health care management can be predicted as a consequence of a direct comparison between needs and results in the various Regions of the Country.
