[Cost-effectiveness analysis of renal replacement therapies: how should we design research on these interventions in Brazil?].

This study aims to contribute to the discussion on the possibility of applying health economics assessment, specifically the cost-effectiveness technique, to renal replacement therapies for end-stage renal failure. A review was conducted on the interventions and their alternative courses from the perspective of the various methodological proposals in the literature, considering the availability of data and information in Brazil to back this type of research.
