*Purpose: To investigate the frequency, correlates, and outcomes associated with prescription opioid and benzodiazepine use before and after lung transplant (LuTx).
*Methods: We examined a linkage of Scientific Registry of Transplant Recipients data with records from a pharmaceutical claims warehouse to characterize prescription opioid and benzodiazepine use in the years before and after LuTx. Associations (adjusted hazard ratio, LCLaHRUCL) with death were examined by Cox regression, adjusted for baseline patient, donor, and transplant factors.
*Results: Among 11,568 LuTx recipients (2008-2017), 33.7% filled an opioid prescription in the year before transplant; use was more common among those who were younger, black or Hispanic, less than college educated, or on dialysis, extracorporeal membrane oxygenation, or ventilator support. Benzodiazepine use was higher among those who also filled opioids: 28% among those without prescription opioid use; 56% among those with the highest level opioid use (>2000 annual morphine equivalents) (Fig 1A). Pre-LuTx opioid use was associated with a graded increase in mortality over the first year post-LuTx (Fig 1B), with a 40% mortality increase for those with highest use (aHR, 1.191.401.75). Benzodiazepine use was also associated with increased mortality, with 60% increased risk for those who filled both short- and long-acting (aHR, 1.181.602.22). Independent effects were persistent when opioids and benzos were co-entered in the same model, but interactions were not observed. Similar risk relationships occurred for prescription use in the year after LuTx, such that the highest level opioid use (aHR, 1.551.761.89), and use of both short- and long-acting benzodiazepines (aHR, 1.241.641.92), were each associated with increased mortality over >1-5 years.
*Conclusions: While associations may, in part, reflect underlying conditions or behaviors, prescription opioid and benzodiazepine use history is relevant in assessing and monitoring LuTx candidates and recipients. Future research is needed to examine mechanisms of these associations, and to develop strategies to improve outcomes.
