Brief Summary:
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 liberation from RRT and kidney recovery. The secondary hypothesis of the WISDOM trial is that lower dose-intensity is superior to current standard guideline-directed CRRT dose-intensity for critically ill patients with AKI with respect to duration of CRRT and successful liberation from RRT and kidney recovery.
Justification: No randomized controlled trial (RCT) to date has specifically evaluated the lower dose-intensity threshold for critically ill patients receiving CRRT. Specifically, there has been no specific evidence or guidance on the minimum dose-intensity targets for patients receiving CRRT. This is important for several reasons. First, CRRT is an invasive, resource intensive and expensive therapy. As such, there should be a concerted effort to minimize time on RRT and facilitate early recovery and weaning. Second, abundant evidence derived from secondary analyses have suggested that higher CRRT dose-intensity can propagate oliguria, prolong CRRT therapy and delay kidney recovery. This would imply that lower dose-intensity may facilitate kidney recovery and earlier weaning from CRRT. Third, there may be added implications of higher dose-intensity, including prolongation of non-renal organ support, such as delay in weaning from invasive mechanical ventilation. Fourth, evidence derived from observational registries show that lower CRRT dose-intensity, in the range proposed in this trial, provides comparable efficacy in azotemic, metabolic and acid-base homeostasis with similar outcomes. Observational data have suggested a prescribed CRRT dose-intensity of 15 mL/kg/hr may be sufficient for metabolic and azotemic control and is not associated with worse outcomes compared with guideline directed dose-intensity. This is lower quality evidence, however, implies that lower dose-intensity may be acceptable and safe. Fifth, it is plausible that following a short period of metabolic stabilization with CRRT, the minimum recommended CRRT dose-intensity of 20-25 mL/kg/hr may be excessive and have unmeasurable harm (e.g., excessive clearance of electrolytes, micronutrients, and medications \[antimicrobials\]). Finally, the prescription of a lower CRRT dose-intensity may have meaningful impact on reducing bedside nursing workload (e.g., fewer replacement solution bag changes) and reducing costs attributable to CRRT (e.g., lower effluent rates will reduce total replacement solution utilized).
While this proposal outlines a pilot feasibility trial, it is aimed at performing a larger rigorous RCT that will generate generalizable and high-quality evidence to impact clinical practice. The findings of the main phase of the WISDOM trial will provide clearer evidence to guide the prescription of a minimal dose-intensity for patients receiving CRRT. While this may be an effluent dose of 20-25 mL/kg/hr, it is entirely plausible that this will be a lower dose-intensity.
Objectives: The overall WISDOM trial program will address whether a lower CRRT dose-intensity in critically ill patients with AKI is non-inferior to standard CRRT dose-intensity and will secondarily address whether lower CRRT dose intensity will shorten total CRRT duration and improve kidney recovery compared with standard CRRT dose-intensity.
