Supplementary Material for: Early Treatment with Human Albumin Solution in Continuous Renal Replacement Patients

Aims: To study the impact of early human albumin solution (HAS) in continuous renal replacement therapy (RRT) patients. Methods: Analysis of Randomized Evaluation of Normal versus Augmented Level (RENAL) RRT trial data. Results: Of 1,464 patients, 500 (34%) received early albumin. These patients had higher illness severity scores, greater use of mechanical ventilation, and 90-day mortality (51 vs. 41%; p p = 0.62). On Cox proportional hazards regression, with standardized inverse probability of treatment weighting, early albumin was not associated with increased mortality (hazard ratio [HR]: 1.23, 95% CI: 0.97–1.55; p = 0.09) or recovery to RRT independence (HR: 0.92, 95% CI: 0.78–1.10; p = 0.38). Conclusions: Early albumin was administered to one-third of RENAL trial patients and in those with greater illness severity. Early albumin was not independently associated with mortality risk or rate of recovery to RRT independence.
