Economic evaluation of different treatment modalities in acute kidney injury.

Background: Major controversy exists regarding the preferred treatment option for acute kidney injury (AKI). The purpose of this study was to assess the incremental cost-effectiveness of continuous renal replacement therapy (CRRT) versus intermittent renal replacement therapy (IRRT) and conservative (CONS) AKI treatment in Belgium.

Methods: An area-under-the-curve model based on survival analysis was used to estimate costs and health outcomes using a 2-year time horizon.
