Abstract:
Hemodialysis (HD) is replacing kidney function by using a semi -permeable membrane in dialysis machine to filter wastes and water from the blood to dialysis fluid. Water treatment plays a vital role in the delivery of safe and effective hem dialysis (HD).
To assess of Water quality of dialysis two methods are used the first method is questionnaire targeted the medical engineers working in 10 of dialysis centers in state, the second method is monitoring chemical contamination in five dialysis centers using chemical analysis for treated water. The questionnaire included the types of tests carried out to monitor system efficiency and control of microbial and chemical contamination, as well as questions to identify the most important problems facing dialysis centers and prevent the application of quality control .As result of following the recommendations of American Association for the Advancement of Medical Instrumentation (AAMI) in monitoring and maintenance of the work of water treatment system the purity of treated water will increase and this reduces the risk of exposure to chemical and microbiological related to water, thus providing good health care. By analyzing the result of questionnaire found that 38% of dialysis centers are following the recommendations of (AAMI )because the tests conducted to monitor the work of water treatment unit were insufficient and were not done in some centers on regular basis, there is no monitoring to chemical contamination ,but on the other hand there are monitoring to microbiological contamination in all dialysis centers. Also by using statistical analysis program SPSS for the results of chemical analysis for treated water of five samples found that 80% of samples aren't pure and that meet the research problem statement there is lack of purity of treated water for hemodialysis.
