Supplementary Material for: Variation in the Care of Acute Liver Failure: A Survey of Intensive Care Professionals

<b><i>Introduction:</i></b> Acute liver failure (ALF) is a rare disease with potentially high mortality. We sought to assess the individual approach to ALF by intensive care unit (ICU) professionals. <b><i>Methods:</i></b> Cross-sectional survey of ICU professionals. Web-based survey capturing data on respondents’ demographics, characteristics of patients with ALF admitted to ICU, and their management. <b><i>Results:</i></b> Among 204 participants from 50 countries, 140 (68.6%) worked in Europe, 146 (71.6%) were intensivists, 142 (69.6%) admitted &lt;25 patients with ALF per year, and 166 (81.8%) reported &lt;25% of patients had paracetamol-related ALF. On patients’ outcomes, 126 (75.0%) reported an emergency liver transplantation (ELT) rate &lt;25% and 140 (73.3%) a hospital mortality rate &lt;50%. The approach to ALF in the ICU varied with age, region, level of training, type of hospital, and etiology (prescribing N-acetylcysteine for paracetamol toxicity, triggers for endotracheal intubation, measurement of and strategies for lowering serum ammonia, extracorporeal device deployment, and prophylactic antibiotics). <b><i>Conclusions:</i></b> The management of patients with ALF by ICU professionals differed substantially concerning the relevant clinical measures taken. Further education and high-quality research are warranted.
