Summary

A pilot randomized clinical trial comparing a protocol-based fluid management strategy to usual care in critically ill patients receiving kidney replacement therapy. The fluid management protocol is intended to achieve neutral or negative daily fluid balance by both preventing and treating fluid accumulation.

Detailed description

Severe acute kidney injury (AKI) in the intensive care unit (ICU) is almost uniformly complicated by fluid accumulation, thus making fluid removal a central component of the renal replacement therapy (KRT) prescription. Whereas the achievement and maintenance of euvolemia are critical objectives in the care of critically ill patients with severe AKI, there remain important knowledge gaps in our ability to effectively and safely deliver ultrafiltration. Multisystemic congestion resulting from fluid accumulation is believed to mediate adverse outcomes in this population and the timely use of mechanical fluid removal may improve prognosis. However, fluid removal may be associated with hemodynamic instability during KRT which may precipitate complications. The optimal fluid management strategy is currently unknown. The study is a pilot randomized clinical trial comparing a protocol-based fluid management strategy with usual care in critically ill patients receiving KRT. The fluid management protocol is intended to achieve neutral or negative daily fluid balance by both preventing and treating fluid accumulation. The protocol was designed to provide a standardized framework to prescribe fluid removal while allowing the attending care team to modify treatment targets according to their clinical evaluation. The primary objective of this trial is to determine whether the intervention results in a difference in cumulative fluid balance from randomization to 5 days. Feasibility will be documented including the ability to enroll the target population, protocol adherence, and the capacity to achieve follow-up through 90 days. Secondary outcomes will also include short-term patient outcomes, safety outcomes, and health resource utilization related to KRT delivery.

Interventions

Type	Name	Description
OTHER	Protocol-based fluid management	Fluid removal will be prescribed using a standardized template updated at least once per working day, before noon of each day, by the attending care team. This protocolized prescription will contain three components. Fluid removal will be prescribed using a standardized template updated at least once per working day, before noon of each day, by the attending care team. This protocolized prescription will contain three components. The first component of this prescription will be to define the 24h-fluid balance target either aiming for a negative fluid balance of 2 to 3% body weight (1.4-2.1 liters in a 70 Kg participant) (Option 1) or by aiming to avoid fluid accumulation by targeting a neutral fluid balance within 0.5% of body weight variation (-350 to +350 mL in a 70 Kg participant) (Option 2). The second component is to pre-specify a prescription for fluid removal using KRT. The third component is to prompt a daily re-evaluation of fluid intake by the attending care team.
OTHER	Usual care	The net fluid removal and the rate of net fluid removal will not be protocolized and will be prescribed and adjusted according to the attending care team without any specific guidance. The use of the documents provided for the intervention group will not be permitted in the control arm.
