Comparing low and standard dose-intensity continuous renal replacement therapy in critically ill patients

LoW Dose-Intensity vs. Standard Dose-Intensity COntinuous Renal ReplaceMent Therapy in Critically Ill Patients (WISDOM): A Pilot Randomized Trial

Not applicable Interventional University of Alberta · NCT06446739

What this trial studies

The WISDOM trial aims to evaluate whether a lower dose-intensity of continuous renal replacement therapy (CRRT) is as effective as the standard dose-intensity for critically ill patients suffering from acute kidney injury (AKI). This interventional study will compare the outcomes of patients receiving lower dose-intensity CRRT against those receiving the standard guideline-directed dose. The primary goal is to determine if the lower dose is non-inferior in terms of CRRT duration and kidney recovery. Additionally, the study will assess if the lower dose can lead to shorter CRRT duration and improved recovery outcomes. This trial is significant as it addresses a gap in current clinical guidelines regarding the minimum effective dose of CRRT.

Who should consider this trial

Good fit: Ideal candidates for this study are critically ill adults aged 18 years and older who are expected to receive continuous renal replacement therapy for acute kidney injury.

Not a fit: Patients with end-stage kidney disease requiring maintenance dialysis or those needing higher dose-intensity CRRT will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more cost-effective and less invasive treatment options for critically ill patients with acute kidney injury.

How similar studies have performed: While previous studies have explored CRRT dose-intensity, this trial is novel as it specifically investigates the lower dose-intensity threshold, which has not been previously evaluated in randomized controlled trials.
