Água para hemodiálise: estudo comparativo entre os resultados das análises fiscais e as análises de rotina realizadas em unidades de diálise no estado do Rio de Janeiro Water for hemodialysis: comparative study between fiscal analysis and routine analysis in dialysis units in the state of Rio de Janeiro

Hemodialysis and renal transplant are both modalities of renal replacement therapy that allow patients to maintain a good quality of life. Water is a major component used in this procedure and proper maintenance is very important as the presence of hidden bacteria and other lowmolecular-weight organisms could contaminate it. in Brazil, as a determination from ANViSA, water quality should be monitored monthly through routine analyses (rAs) of dialysis units (DUs). in rio de Janeiro, monitoring of such guidelines is provided by the Program for Monitoring Water Quality (PMWQ) of the Sanitary Control Agency in conjunction with iNCQS/FioCrUZ through annual supervised analyses (SAs). Objective: to compare the results of rAs conducted by DUs with the results obtained by SAs. Methods: We conducted a transversal comparative study between the results of rAs and SAs at 4 selected points in the treatment system and water distribution of 22 DUs. Results: Eighteen of the 22 DUs showed similar results (81.8%) between the samples, whereas 4 (18.2%) presented different results. of these, 3 had SAs with unsatisfactory results and rAs with satisfactory results, whereas 1 had SAs with satisfactory results and rAs with unsatisfactory results. Conclusion: SAs and rAs showed concordant results for more than 80% DUs, indicating that the instruments for assessing the quality of the DU water currently employed by the Department of Health are able to accurately represent the results of rAs.
