| Abstract: | The EDTNA/ERCA survey of the treatment of water for dialysis was the third project organised through the Collaborative Research Programme (CRP). Data was collected from 69 haemodialysis facilities in 14 countries. Water quality in European dialysis units was mainly self‐regulated. The majority of centres aimed to meet the requirements of the European Pharmacopoeia, but only 50% carried out tests to check compliance. All facilities used reverse osmosis to treat water for dialysis, most also used softening and carbon adsorption. There was a wide variation in policies for the maintenance of carbon filters, and for the control and monitoring of contamination in the distribution system. Endotoxin tests carried out in 27 facilities showed that higher levels of contamination are associated with systems that are infrequently disinfected, and also with older system designs. The survey indicated that guidelines for water treatment are urgently needed. EDTNA/ERCA guidelines for microbiological monitoring are now being drafted, additional guidelines are under consideration. |
