ObjectiveThe study objective was to determine whether donor substance abuse (opioid overdose death, opioid use, cigarette or marijuana smoking) impacts lung acceptance and recipient outcomes.MethodsDonor offers to a single center from 2013 to 2019 were reviewed to determine if lung acceptance rates and recipient outcomes were affected by donor substance abuse.ResultsThere were 3515 donor offers over the study period. A total of 154 offers (4.4%) were opioid use and 117 (3.3%) were opioid overdose deaths. A total of 1744 donors (65.0%) smoked cigarettes and 69 donors (2.6%) smoked marijuana. Of smokers, 601 (35.0%) had less than 20 pack-year history and 1117 (65.0%) had more than 20 pack-year history. Substance abuse donors were younger (51.5 vs 55.2 P < .001), more often male (65.6 vs 54.8%, P < .001), more often White (86.2 vs 68.7%, P < .001), and had hepatitis C (8.3 vs 0.8%, P < .001). Donor acceptance was significantly associated with brain dead donors (odds ratio, 1.56, P < .001), donor smoking history (odds ratio, 0.56, P < .001), hepatitis C (odds ratio, 0.35, P < .001), younger age (odds ratio, 0.98, P < .001), male gender (odds ratio, 0.74, P = .004), and any substance abuse history (odds ratio, 0.50, P < .001), but not opioid use, opioid overdose death, or marijuana use. Recipient survival was equivalent when using lungs from donors who had opioid overdose death, who smoked marijuana, or who smoked cigarettes for less than 20 patient-years or more than 20 patient-years, and significantly longer in recipients of opioid use lungs. There was no significant difference in time to chronic lung allograft dysfunction for recipients who received lungs from opioid overdose death or with a history of opioid use, marijuana smoking, or cigarette smoking.ConclusionsDonor acceptance was impacted by cigarette smoking but not opioid use, opioid overdose death, or marijuana use. Graft outcomes and recipient survival were similar for recipients of lungs from donors who abused substances.Copyright © 2022 The American Association for Thoracic Surgery. Published by Elsevier Inc.
