ABSTRACT
Extracorporeal membrane oxygenation (ECMO) has been used in highly selected COVID-19 patients with severe respiratory failure. Scarce data exist on long-term outcomes of these patients. We performed a single-center prospective evaluation of consecutive COVID-19 ECMO patients successfully discharged from the intensive care unit between February 2020 and January 2022. Physical, cognitive and psychological outcome was assessed at 3, 6, and 12 months by in-person evaluation. All the 34 discharged patients (median age 49 years old) were alive at one year, and 25 of them were evaluated at the follow-up clinic. 67% of patients had muscle weakness, with improvement over time (p = 0.032). The percentage of patients able to return to work progressively increased, up to 86% at 1 year. 23% of patients experienced fatigue. Participation restriction improved over time for both physical (p = 0.050) and emotional (p = 0.005) problems. Cognitive impairment, anxiety, and depression occurred in 29%, 29%, and 23% of patients, respectively, with no changes over time. Health-related quality of life was good. In conclusion, COVID-19 ECMO patients suffer from significant long-term sequelae. However, multidimensional outcomes continued to improve over the follow-up time.
