Inferior Liver Transplant Outcomes during early COVID-19 pandemic in United States.

BACKGROUND

: Since its declaration as a global pandemic on March11 2020, COVID-19 has had a significant effect on solid-organ transplantation. The aim of this study was to analyze the impact of COVID-19 on Liver transplantation (LT) in United States.

METHODS

: We retrospectively analyzed the United Network for Organ Sharing database regarding characteristics of donors, adult-LT recipients, and transplant outcomes during early-COVID period (March 11- September 11, 2020) and compared them to pre-COVID period (March 11 - September 11, 2019).

RESULTS

: Overall, 4% fewer LTs were performed during early-COVID period (4107 vs 4277). Compared to pre-COVID period, transplants performed in early-COVID period were associated with: increase in alcoholic liver disease as most common primary diagnosis (1315 vs 1187, < 0.01), higher MELD score in the recipients (25 vs 23, <0.01), lower time on wait-list (52 vs 84 days, <0.01), higher need for hemodialysis at transplant (9.4 vs 11.1%, =0.012), longer distance from recipient hospital (131 vs 64 miles, <0.01) and higher donor risk index (1.65 vs 1.55, <0.01). Early-COVID period saw increase in rejection episodes before discharge (4.6 vs 3.4%, =0.023) and lower 90-day graft/patient survival (90.2 vs 95.1 %, <0.01; 92.2 vs 96.5 %, <0.01). In multivariable cox-regression analysis, early-COVID period was the independent risk factor for graft failure at 90-days post-transplant (Hazard Ratio 1.77, <0.01).

CONCLUSIONS

: During early-COVID period in United States, overall LT decreased, alcoholic liver disease was primary diagnosis for LT, rate of rejection episodes before discharge was higher and 90-days post-transplant graft survival was lower.
