Abstract: Objective: The aim of this study was to compare the efficacy of bioelectrical impedance analysis against clinical evaluation for the adequacy of DW in hemodialysis (HD) patients.

Material and Methods: A randomized crossover study with patients randomized into two groups: A – DW determined by clinical evaluation (CA), and B – DW evaluated by bioimpedance analysis (BIA), for 4 weeks. After this period, the crossover to the alternate treatment was performed for a further 4 weeks.

Results: The study included 57 CKD patients on HD. No statistical difference was found when comparing the two treatments for data related to blood pressure, hydration parameters and DW, regardless of group.

Conclusions: The results suggest equivalence between the treatments of BIA and CA for determining DW and guiding HD ultrafiltration.
