Plain English Summary

Background and study aims
Many intensive care unit (ICU) patients develop edema (collection of fluid in the body) due to the fluids injected through the vein used for resuscitation. Edema has been associated with longer ICU stay and higher death rate. Thus removal of fluid is important. We aim to study whether the addition of albumin, which encourages the movement of fluid from tissues back into blood vessels, can improve the effectiveness of diuretics (drugs that increase production of urine), the basis of edema treatment.

Who can participate?
Adults admitted to the intensive care unit for any reason, who have normal blood flow and low protein levels in blood, and judged to be in need of diuresis (increased production of urine).

What does the study involve?
Participants will be randomly allocated to receive albumin or placebo (dummy), given
two hours before the diuretic treatment. Study treatment will continue for 72 hours, or less if the doctors decide that further diuresis is unnecessary, serum albumin levels normalize, or the patient leaves the ICU. Study treatment will also be held if the doctors are withholding the diuretic treatment. If diuresis is resumed, the patient will restart their assigned treatment (albumin or placebo). 

What are the possible benefits and risks of participating?
Patients will receive access to a potentially beneficial strategy of diuresis involving the use of
albumin in addition to the usual care. There are no known cases of transmission of germs from receiving albumin despite decades of use, and the overall risk is therefore extremely remote. Some study tests will require one extra tube of blood to be collected; all other data collection and treatment is as per routine ICU care and poses no extra risk. 

Where is the study run from?
This study will be conducted at intensive care units of Juravinski Hospital and Hamilton General Hospital, Hamilton, Ontario, Canada.

When is study starting and how long is it expected to run for?
Recruitment is anticipated to begin early 2014, and continue for 6-7 months, or until 50 patients are recruited.

Scientific titleHyperoncotic albumin to improve diuresis in critically ill patients: a pilot randomized controlled trial
Study acronymFADE
Study hypothesisWe hypothesize that hyperoncotic albumin, given prior to diuretics, in edematous critically ill patients with hypoproteinemia, will improve diuresis, oxygenation, and hemodynamics. This trial is a pilot RCT to assess the feasibility of such a trial.

On 17/04/2014 the anticipated start date was changed from 01/01/2014 to 04/03/2014.
Ethics approval(s)Hamilton Integrated Research Ethics Board (HIREB), 04/03/2014, ref: REB #14-002
ConditionEdema
InterventionPatients are randomized to two groups:
1. 25% albumin, 100 mL intravenous twice daily
2. Placebo, during the duration of diuresis.
Patients will be followed up for 30 days or hospital discharge, which ever is sooner.

Intervention typeOther
Primary outcome measureCurrent primary outcome measures as of 17/04/2014:
Our primary outcome is feasibility, including three components:
1. Adherence to protocol (administration of first dose of study treatment within 2 hours of furosemide; proportion of patients receiving all six doses of study treatment; absence of cointervention in placebo arm as documented in the medication administration record)
2. Randomization rate of eligible patients
3. Collection of study data (including blood chemistry, hemodynamic, and oxygenation data)

Previous primary outcome measures:
Our primary outcome is feasibility, including three components:
1. Adherence to protocol (administration of first 3 doses of study treatment, within 2 hours of furosemide, absence of cointervention in placebo arm, as documented in the medication administration record)
2. Randomization rate of eligible patients
3. Collection of study data (including blood chemistry, hemodynamic, and oxygenation data)
Secondary outcome measuresCurrent secondary outcome measures as of 17/04/2014:
Clinical outcomes will be secondary in this pilot study:
1. Ventilator-free days and duration of mechanical ventilation
2. Episodes interrupting treatment with furosemide
3. Fluid balance, oxygenation, hemodynamic status
4. Changes in serum electrolytes and albumin at day 1, 3, 5
5. Changes in colloid osmotic pressure at day 1, 3, 5
6. ICU and hospital mortality

Previous secondary outcome measures:
Clinical outcomes will be secondary in this pilot study:

2. Serum chemistry data and blood gas measurements
3. Colloid osmotic pressure
4. ICU and hospital mortality
