Abstract
Under US Public Health Service guidelines, organ donors with risk factors for human immunodeficiency virus (HIV), hepatitis B virus (HBV), or hepatitis C virus (HCV) are categorized as increased risk donors (IRD). Previous studies have suggested that IRD organs are utilized at lower rates than organs from standard risk donors (SRD), but these studies were conducted prior to universal donor nucleic acid test screening. We conducted risk-adjusted analyses to determine the effect of IRD designation on organ utilization using 2010-2017 data (21626 heart, 101160 kidney, 52714 liver, and 16219 lung recipients in the United States) from the Organ Procurement and Transplantation Network. There was no significant difference (P<.05) between risk-adjusted utilization rates for IRD vs SRD organs for adult hearts and livers and pediatric kidneys, livers, and lungs. Significantly lower utilization was found among IRD adult kidneys, lungs, and pediatric hearts. Analysis of the proportion of transplanted organs recovered from IRD by facility suggests that a subset of facilities contribute to the underutilization of adult IRD kidneys. Along with revised criteria and nomenclature to identify donors with HIV, HBV, or HCV risk factors, educational efforts to standardize informed consent discussions might improve organ utilization.
