Abstract Background Ex vivo lung perfusion (EVLP) conducted outside of the transplant center has increased in recent years to mitigate its limitation by resources and expertise. We sought to evaluate EVLP performed at transplant centers and externally. Methods Lung transplant recipients were identified from the United Network for Organ Sharing Database. Recipients were then stratified into two groups based where they were perfused: Transplant Program (TP) or External Perfusion Centers (EPC). The groups were assessed with comparative statistics and long‐term survival was assessed by Kaplan–Meier method. The groups were then 1:1 propensity and this process was repeated. Results EPC use was generally restricted to the Southern United States. Following matching, there were no significant differences in post‐operative outcomes to include post‐operative stroke, dialysis, airway dehiscence, ECMO use, ventilator use or incidence of primary graft dysfunction Grade 3. Adjusted 3‐year survival was 68.9% (95% Confidence Interval CI: 60.9%–77.9%) for the TP group and 67.6% (95% CI: 61.0%–74.9%) for the EPC group ( p = 0.69). In allografts with extended ischemia (14+ h), those in the TP group had significantly longer length of stay, prolonged ventilation and treated rejection in the 1st year, though no significant difference in mid‐term survival ( p = 0.66). Conclusion EVLP performed at an EPC can be carried out with results and survival similar to allografts undergoing EVLP at a TP. EPCs will extend the valuable resource of EVLP to lung transplant programs without the resources to perform EVLP.
