LoW Dose-Intensity vs. Standard Dose-Intensity COntinuous Renal ReplaceMent Therapy in Critically Ill Patients (WISDOM): A Pilot Randomized Trial
University of Alberta
Summary
An estimated 10-15% of critically ill patients with acute kidney failure in the intensive care unit receive acute dialysis therapy. The majority of these patients initially receive a continuous form of dialysis therapy call continuous renal replacement therapy (CRRT). Prior studies have suggested that higher CRRT dose-intensity improved health outcomes for these patients; however, this was not found in high-quality clinical trials. These more recent trials suggested a lower range of dose-intensity compared with the higher range as the new standard of care. This was incorporated into guidelines. To date, no clinical trials have evaluated this lower range and specifically, it is plausible that an even lower dose-intensity of CRRT may be well tolerated, safe, associated with similar outcomes and be more cost-effective. This is the objective of the WISDOM trial, to compare the guideline standard with lower dose-intensity among patients who are started on CRRT in the intensive care unit.
Description
Purpose: To primarily determine whether a lower CRRT dose-intensity in critically ill patients with acute kidney injury (AKI) is non-inferior to standard CRRT dose-intensity and to secondarily determined whether lower CRRT dose intensity will shorten total CRRT duration and improve kidney recovery compared with standard CRRT dose-intensity. Hypothesis: The primary hypothesis of the WISDOM trial is that lower CRRT dose-intensity is non-inferior to current standard guideline-directed CRRT dose-intensity for critically ill patients with AKI with respect to duration of CRRT and successful liberat…
