Recovery After Dialysis-Requiring Acute Kidney Injury

The recent landmark Artificial Kidney Initiation in Kidney Injury (AKIKI) trial showed that a delayed strategy for RRT initiation among patients with incident stage 3 AKI - in which RRT was delayed unless specific metabolic or clinical indications for RRT were present - was safe and averted the need for RRT in nearly half of the critically ill participants, in comparison to an early RRT initiation strategy. The hypothesis for this study is: for prevalent patients with established AKI-D, a conservative dialysis strategy - in which hemodialysis is not continued unless specific metabolic or clinical indications for RRT are present - will shorten time to RRT-independence and improve the likelihood of renal recovery. The RAD-AKI Pilot Study is a 2-arm randomized clinical trial of hospitalized patients with dialysis-requiring acute kidney injury (RAD-AKI) that will compare conventional thrice-weekly intermittent hemodialysis dialysis (control) to a "conservative dialysis strategy." The primary objective of this pilot study is to assess the safety and feasibility of the proposed intervention and study design.
