A New Water Quality Standard for Better Patient Outcomes
The recent adoption of ISO 13959:2009 by AAMI means the quality of water used in dialysis treatment will increase. The new standard has 2 important aspects to it. First, acceptable microbiological levels have been reduced by more than 50%, as noted in the chart below. Second, the testing protocol used to determine bacteria levels is a much more sensitive cultivation technique. The net result is that existing water system designs may or may not consistently produce water that meets the new standards. |
