BACKGROUND Liver transplant may require large‐volume plasma transfusion with increased risk of transfusion‐transmitted infection (TTI). Pathogen inactivation of plasma with amotosalen‐UVA offers the potential to mitigate TTI risk. STUDY DESIGN AND METHODS A retrospective cohort design was used to compare the therapeutic efficacy and key safety outcomes for liver transplants supported with quarantine plasma (Q‐FFP [reference]) or amotosalen‐UVA plasma (IBS plasma [test]). The outcomes evaluated were volume of plasma, the numbers of red blood cell (RBC) components, and the total dose of platelets (PLTs) transfused during and 7 days after transplant. The safety outcomes were acute hepatic artery thrombosis (HAT) and mortality. RESULTS Transplantation and transfusion records for 212 Q‐FFP transplants and 215 IBS plasma transplants were reviewed. Not all transplants required plasma; 161 received Q‐FFP and 174 received IBS plasma. Among the transplants that required plasma, there were significant differences in median values between cohorts for delay to transplantation (p = 0.002), model end‐stage liver disease score (p < 0.001), pretransplant hematocrit (p = 0.006), and graft cold perfusion time (p = 0.033). The median volumes of plasma transfused were not different for test and reference (2.160 L vs. 1.969 L, p = 0.292). Transplants in the test cohort required a mean of 3.7% more RBC components (p = 0.767) and on average a 16.5% increase in total PLT dose (p = 0.518). No significant differences were observed for the frequency of acute HAT or mortality. CONCLUSION In this retrospective study, IBS plasma provided therapeutic support of liver transplant not different from Q‐FFP.
