National Trends in Consent to Accept Hepatitis C Virus Positive Donor Organs

As hepatitis C virus (HCV) infection is now curable, HCV-positive donor organs have expanded the deceased donor pool. Using OPTN data, we identified adult kidney, liver, heart, and lung candidates listed between 2016-2025 and evaluated rates of consent to accept HCV antibody-positive (Ab+) and HCV viremic (NAT+) organs. Temporal trends were described, and multilevel modified Poisson regression with center-level random effects was used to estimate adjusted risk ratios for candidate factors and quantify center variation using median incidence rate ratios (MIRR). Rates of consent to accept both HCV Ab+ and NAT+ organs rose over time. By the end of follow-up, consent rates for HCV Ab+ organs were 63.1% for kidney, 80.6% for liver, 73.3% for heart, and 72.1% for lung candidates, and consent rates for NAT+ organs were 44.9%, 70.7%, 50.5%, and 46.1%, respectively. Associations between candidate characteristics and consent were small after adjustment for center, whereas center effects were large. For HCV Ab+ organs, MIRRs were 6.31 (kidney), 2.48 (liver), 2.90 (heart), and 4.36 (lung); for NAT+ organs, MIRRs were even higher, 9.65, 3.19, 4.00, and 7.30, respectively, indicating marked between-center variability. Our analyses suggest that access to HCV-positive organs is influenced more by center practices than patient characteristics.
