Since its emergence in China in late 2019, the coronavirus disease 2019 (COVID-19) outbreak has rapidly posed the risk of critical care resources overload in every affected country. The distribution of the disease among the territories is heterogeneous. Long-range inter-hospital transport of critically ill COVID-19 patients as a way to mitigate the localised pressure from overloaded intensive care units at a national or international level has not been reported yet. The aim of this article was to provide descriptive data about the six collective aeromedical evacuation of COVID-19 patients performed within Europe and French national territory on March 18, 21, 24, 27, 31 and April 3, 2020. Thirty-six patients with acute respiratory distress syndrome (ARDS) were transported aboard six aeromedical evacuation missions. ARDS was moderate (PaO2/FiO2 ratio > 100 and ≤ 200) in 24 patients and mild (PaO2/FiO2 ratio > 200 and ≤ 300) in 12 patients. The median duration of mechanical ventilation in ICU before transportation was 4 days [Interquartile (IQ): 3-5]. The median PaO2/FiO2 ratio was 180 mmHg (IQ: 156-202). The median norepinephrine infusion rate was 0.08 μg/kg/min. No life-threatening event was reported. Collective aeromedical evacuation of COVID-19 critically ill patients could provide a reliable solution to help control the burden of the disease at a national or international level. Future works may evaluate the global safety and effectiveness of aeromedical evacuations in this context.
