Volume-outcome relationship of COVID-19 ECMO. Case volume. Case volume vs. survival in low (n = 96, survival 20%), intermediate (n = 329, survival 30%) and high volume (n = 248, survival 38%) ECMO centers. Annual case volumes prior to the pandemic were defined as low (< 20/year), intermediate (20–49/year) and high (> 50/year). Lower lines (ECMO ICU discharged alive) depict the percentage of patents discharged alive from the ECMO providing ICU. ICU discharge destinations were mainly other ICUs (40%), rehabilitation facilities (33%), or general wards (23%) (data not shown)
