    A New Water Quality Standard for Better Patient Outcomes 

    The recent adoption of higher standards 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 yet includes a deviation to allow for other test methods. The net result is that existing water system designs may or may not consistently produce water that meets the new standards

AAMI Microbiological Standards for Dialysis Water
 Microbiological LevelPrevious StandardsNew StandardsPrevious Action LevelNew Action Level
 Colony Forming Units< 200 CFU/mL< 100 CFU/mL≥ 50 CFU/mL≥ 50 CFU/mL
 Endotoxin Units< 2 EU/mL< 0.25 EU/mL≥ 1 EU/mL≥ 0.125 EU/mL

What Can You or Your Facility Do?
For existing water systems, you should perform testing using the latest standard to ensure that your water system is producing water that meets the new requirements. As a result, you may need to increase the disinfection frequency, or add additional filtration or a combination of both in order to meet the new standard. Mar Cor Purification can help you evaluate the options
