Donation after cardiac death (DCD) donor liver graft is a known risk factor for graft failure secondary to primary non-function (PNF) and/or diffuse cholangiopathy (DC). We aimed to study mortality and graft failure hazard ratio trends among DCD vs. donation after brain death (DBD) recipients.
Retrospective data of adult recipients ≥18 years from the national United Network for Organ Sharing registry 2011-2016 were analyzed. Clinically significant donor, recipient, and operative characteristics were balanced among donor groups using propensity score-matching (PSM). All-cause mortality, all-cause graft failure, graft failure due to DC and PNF were estimated using Cox proportional hazards models.
Among a total of 29573 recipients, 1800 (6.09%) received DCD livers. Overall, PSM DCD recipients should expect worse 2-year all-cause mortality, 2-year all-cause graft failure, 2-year graft failure due to DC, and 1-year graft failure due to PNF in comparison to DBD recipients (HR=1.43, 1.45, 5.24, and 3.08, respectively).PSM all-cause mortality and all-cause graft failure incidence for both DCD and DBD recipients indicate declining trends (P<0.001, <0.001, <0.001, and <0.001, respectively). Whereas PSM incidence of DC is statistically becoming worse for DCD recipients (P=0.004). Among the most recent time period (2015-2016): the hazard for all-cause mortality was null, 39% increased hazard for all-cause graft failure, 449% increased hazard for DC, and 176% increased hazard for PNF among DCD in comparison to DBD.
All-cause PSM mortality and graft failure hazard declined from 2011 through 2016. Based on this trend future DCD and DBD recipients should expect identical two-year survival as well as near similar graft function. However, we are observing more DC recently among DCD recipients. Future data is required to confirm whether DC and PNF outcomes are improving or worsening over time amongst deceased liver transplant recipients.
