Establishing an interhospital ECMO-transport program during a pandemic: Key lessons learned.

Background: The emergence of COVID-19 has amplified the importance of efficient patient transfer, leading to the idea of inter-hospital ECMO transport programs. However, there are limited studies on ECMO transfer protocols and experiences during COVID pandemic. This study aimed to evaluate the effectiveness our transport program and provide insights into establishing and maintaining ECMO programs.

Methods: Over the period from April 2020 to December 2021, 76 patients with severe hypoxic COVID-19 ARDS were transferred to our center under a veno-venous ECMO support. The transfers were performed by the experienced transport ECMO-team, covering both intracity and intercity transports from various hospitals in Istanbul and the Marmara Region.

Results: Mean age was 44 (34-54) years. Time until ECMO initiation was 6 (3-11.2) days. The average transport distance was 36.6 ± 58.7 km. Average intracity and intercity transport distance were 17.5 ± 15.7 and 121 ± 96.6 km, respectively. ECMO wean rate was 40.7% and survival to discharge (home) was 38.1%. No major adverse events occurred during the transfer process. In one transport, the oxygen tank was instantly replenished on the road due to the decrease in the oxygen level in the tank.

Conclusion: In conclusion, this study contributed to the knowledge surrounding ECMO transport programs during pandemics, emphasized the importance of expert coordination and careful patient management with demonstrating feasibility of mobile ECMO program .
