The objectives of this study were to determine whether outcomes of resuscitation with albumin or saline in the intensive care unit (ICU) depend on patients’ baseline serum albumin concentration. In this study we analyse data from a double‐blind, randomized controlled trial. ICUs of 16 hospitals in Australia and New Zealand were included. There was a total of 6045 participants in the saline versus albumin fluid evaluation study. Fluid resuscitation with 4% albumin or saline was observed in patients with a baseline serum albumin concentration of 25 g/L or less or more than 25 g/L. Primary outcome was all‐cause mortality at 28 days. Secondary outcomes were length of stay in the ICU, length of stay in hospital, duration of renal replacement therapy and duration of mechanical ventilation. The odds ratios for death for albumin compared with saline for patients with a baseline serum albumin concentration of 25 g/L or less and more than 25 g/L were 0.87 and 1.09, respectively (ratio of odds ratios 0.80, 95% confidence interval 0.63 to 1.02); P = 0.08 for heterogeneity. No significant interaction was found between baseline serum albumin concentration as a continuous variable and the effect of albumin and saline on mortality. No consistent interaction was found between baseline serum albumin concentration and treatment effects on length of stay in the ICU, length of hospital stay, duration of renal replacement therapy or duration of mechanical ventilation. The outcomes of resuscitation with albumin and saline are similar irrespective of patients’ baseline serum albumin concentration.
