Standard Versus Accelerated Initiation of Dialysis in Acute Kidney Injury

Phase 2
Completed
Conditions
Acute Kidney Injury
Interventions
Other: Standard RRT initiation
Other: Accelerated RRT initiation
Registration Number
NCT01557361
Lead Sponsor
Unity Health Toronto
Brief Summary

The objectives of this trial are to determine whether, in critically ill patients with severe acute kidney injury (AKI), randomization to accelerated initiation of renal replacement therapy (RRT), compared with standard initiation, is:

1. Feasible, in terms of adherence to the protocol (primary outcome), recruitment rates, and achievement of follow-up; and

2. Safe, from the perspective of potential adverse events associated with earlier initiation of RRT

Detailed Description

Acute kidney injury (AKI) is a common and devastating complication of critical illness. Once AKI is established, treatment is largely supportive and no intervention has been found to restore kidney function or improve overall survival. Renal replacement therapy (RRT), usually in the form of hemodialysis, is frequently needed to manage patients with severe AKI. Such patients have an in-hospital mortality that consistently exceeds 50%. Delay in the initiation of RRT has been implicated as a possible contributor to this poor outcome. A recent meta-analysis suggested that earlier initiation of RRT may improve survival. However, completed trials to date have been small, single centre, limited by study quality, and have shown considerable heterogeneity in terms of definitions used for "early" RRT initiation.

The objectives of this trial are to determine whether, in critically ill patients with severe acute kidney injury (AKI), randomization to accelerated initiation of renal replacement therapy (RRT), compared with standard initiation, is:

1. Feasible, in terms of adherence to the protocol (primary outcome), recruitment rates, and achievement of follow-up; and

2. Safe, from the perspective of potential adverse events associated with the earlier or later initiation of RRT

This pilot trial is intended to guide and inform the design of a phase III multicentre randomized trial of accelerated versus standard initiation of RRT in critically ill patients that will evaluate the impact of the intervention on 90-day all-cause mortality and recovery of kidney function.

Arm && Interventions
GroupInterventionDescription
Standard RRT initiationStandard RRT initiationRRT is initiated \>12 hours after eligibility determination. Once a decision is made to start RRT, a dialysis catheter will be placed and RRT initiated as soon as possible.
Accelerated RRT initiationAccelerated RRT initiationA dialysis catheter will be placed and RRT initiated as soon as possible and within 12 hours of eligibility.
Primary Outcome Measures
NameTimeMethod
Feasibility of protocol adherence14 days

\>90% of participants in the accelerated initiation arm start RRT within 12 hours of eligibility AND \>90% of participants randomized to the standard initiation arm who ultimately receive RRT, start RRT at least 12 hours following eligibility determination

Secondary Outcome Measures
NameTimeMethod
Feasibility of 90-day follow-up90 days

Vital status and need for RRT at 90 days are successfully captured in \>95% of participants

Feasibility of enrollment14 days

\>50% of eligible patients are successfully enrolled in the trial

Safety outcomes14 days

Serious adverse effects, with a particular focus on those that are potentially attributable to the study treatment, vascular accesss complications (including hemorrhage, thrombosis and infection) and complications associated with the delivery of RRT (dialysis-associated hypotension, electrolyte abnormalities) will be examined.
