Abstract

Abstract Bioimpedance is largely used in dialysis patients instead, being a simple, precise, noninvasive and inexpensive method to assess fluid status and body composition. This scoping review aims to describe and synthesize scientific evidence on bioimpedance technologies use in dialysis patients. A literature search was done for peer-reviewed journal clinical trials using PubMed/Medline, Scopus and Web of Science databases. The initial search yielded 145 clinical trials; there were 24 duplicated and 90 title-abstract excluded articles. 31 studies were full-text assessed for eligibility for inclusion in the scoping review. There were 23 full-text articles excluded; finally, eight articles were included in the review. The mainly uses for bioimpedance technologies in dialysis patients founded were in fluid volume, dry weight assessment, post-dialysis target weight, and fluid overload management in peritoneal dialysis or hemodialysis patients. Most of the reported primary outcomes in the selected clinical trials were focused on all-cause mortality and hospitalization rate. All the included studies described a significant reduction in the overhydration status in the BIA group. Despite the fact that in many trials use of BIA was not superior to traditional clinical methods, its results have been shown to be similar and not inferior to expert clinical evaluation. Thus, bioimpedance technologies could be very useful when using it as a complement to traditional methods in peritoneal dialysis and hemodialysis patients. Moreover, BIA technologies could be even more
