Uptake and 1-year outcomes of lung transplantation for COVID-19

Objective: End -stage lung disease from severe COVID-19 infection is an increasingly common indication for lung transplantation (LT), but there are limited data on outcomes. We evaluated 1 -year COVID-19 LT outcomes. Methods: We identified all adult US LT recipients January 2020 to October 2022 in the Scientific Registry for Transplant Recipients, using diagnosis codes to identify recipients transplanted for COVID-19. We used multivariable regression to compare in -hospital acute rejection, prolonged ventilator support, tracheostomy, dialysis, and 1 -year mortality between COVID-19 and non-COVID-19 recipients, adjusting for donor, recipient, and transplant characteristics. Results: LT for COVID-19 increased from 0.8% to 10.7% of total LT volume during 2020 to 2021. The number of centers performing LT for COVID-19 increased from 12 to 50. Recipients transplanted for COVID-19 were younger; were more likely to be male and Hispanic; were more likely to be on a ventilator, extracorporeal membrane oxygenation support, and dialysis pre-LT; were more likely to receive bilateral LT; and had higher lung allocation score and shorter waitlist time than other recipients (all P values<.001). COVID-19 LT had higher risk of prolonged ventilator support (adjusted odds ratio, 2.28; P < .001), tracheostomy (adjusted odds ratio 5.3; P < .001), and longer length of stay (median, 27 vs 19 days; P < .001). Risk of inhospital acute rejection (adjusted odds ratio, 0.99; P = .95) and 1 -year mortality (adjusted hazard ratio, 0.73; P = .12) were similar for COVID-19 LTs and LTs for other indications, even accounting for center-level differences. Conclusions: COVID-19 LT is associated with higher risk of immediate postoperative complications but similar risk of 1 -year mortality despite more severe pre-LT illness. These encouraging results support the ongoing use of LT for COVID-19-related lung disease. (J Thorac Cardiovasc Surg 2024;167:549-55)
