The ship has on-board hospital capacity and is the first time that an amphibious assault ship is engaged in this particular condition. The aim is to evaluate the feasibility and safety of prolonged medical evacuation of critical patients with COVID-19.Methods We included 12 patients with confirmed COVID-19 infection: six ventilated patients with acute respiratory distress syndrome and six non-ventilated patients with hypoxaemia. Transfer on an amphibious assault ship lasted 20 hours. We collected patients’ medical records: age, comorbidities, COVID-19 history and diagnosis, ventilation supply and ventilator settings, and blood gas results. We calculated oxygen consumption (OC).Results All patients had a medical history. The median delay from onset of symptoms to hospitalisation was 8 (7–10) days. The median Sequential Organ Failure Assessment score on admission was 3 (2–5). There was no significant increase in oxygen during ship transport and no major respiratory complication. There was no significant increase in arterial oxygen pressure to fractional inspired oxygen ratio among ventilated patients during ship transport. Among ventilated patients, the median calculated OC was 255 L (222–281) by hours and 5270 L (4908–5616) during all ship transport. Among non-ventilated patients, the median calculated OC was 120 L (120–480) by hours and 2400 L (2400–9600) during all ship transport.Conclusion The present work contributes to assessing the feasibility and safety condition of critical COVID-19 evacuation on an amphibious assault ship during an extended transport. The ship needs to prepare a plan and a specialised intensive team and conduct patient screening for prolonged interhospital transfers.
