Posthospitalization outcomes after extracorporeal membrane oxygenation (ECMO) for COVID-19.

ABSTRACT

BACKGROUND: Critical illness from COVID-19 is associated with prolonged hospitalization and high mortality rates. Extracorporeal membrane oxygenation is used for refractory severe acute respiratory distress syndrome in COVID-19 with outcomes comparable to other indications for extracorporeal membrane oxygenation. However, long-term functional outcomes have yet to be fully elucidated. METHODS: We performed a retrospective chart review of 24 consecutive patients who required extracorporeal membrane oxygenation due to COVID-19 associated severe acute respiratory distress syndrome and survived to hospital discharge. After hospitalization, we contacted patients and administered the Patient-Reported Outcomes Measurement Information System (PROMIS) Global-10 tool to assess longer-term outcomes. We abstracted demographics, clinical course, outcomes, and disposition variables from the electronic medical record. Descriptive statistical analysis was used on the retrospective data collection. RESULTS: Inpatient data were analyzed for 24 patients, and 21 of 24 (88%) patients completed the Patient-Reported Outcomes Measurement Information System tool at an average of 8.8 months posthospitalization. At hospital discharge, 62.5% of patients had ongoing oxygen requirements (nasal cannula, trach collar, or mechanical ventilation); 70.8% were discharged to a location other than home. However, at the time of follow-up, only 9.5% of patients required supplemental oxygen, all tracheostomies had been removed, and all patients resided at home. Patients reported relatively high levels of global physical function, and though there was a high reported incidence of fatigue, overall pain scores were low. CONCLUSION: Long-term outcomes after extracorporeal membrane oxygenation for severe acute respiratory distress syndrome from coronavirus disease 2019 are promising. Extracorporeal membrane oxygenation therapy may confer morbidity benefits in patients with coronavirus disease and remains a valuable modality with excellent functional outcomes and preserved quality of life for survivors.
