Background: Lung transplant (LT) allocation utilizes a scoring system to prioritize patients, although data evaluating the access by gender and race remains limited. The study objective was to determine whether gender and racial disparities exist in patients listed for LT.
Methods: This was a retrospective analysis using the Organ Procurement and Transplant Network database of patients listed for a LT from 1984 until 2019. Nominal multivariate logistic regression analysis was performed to evaluate LT allocation by gender, race, and primary lung disease. Kaplan-Meier curves were constructed to compare rates of mortality over time.
Results: Sixty thousand eight hundred and forty-seven patients were listed between February 1984 and September 2019. Males comprised the majority of listed and transplanted patients at 51.7% and 55.8% respectively. In the LAS era, the median waiting list time for transplanted males was 43 days (interquartile range [IQR] 13-126), and females waited a median of 80 days (IQR 24-233) (p < .001). Persons of White race accounted for 82.6% and 84.3% of listed and transplanted patients respectively. Logistic regression analysis found that in the LAS era, males had an increased odds for LT allocation (OR 1.19, CI 1.12-1.27, p < .001) compared to females, and persons of White race (OR 1.23, CI 1.16-1.32, p < .001) compared to all other races combined.
Conclusions: The majority of listed and transplanted patients in the United States were males and persons of White race. Also, being a male or person of White race had an outcome favoring lung transplant allocation compared to an appropriately matched person of another gender or race.
