Donors in lung transplantation: does age matter?

A best-evidence topic was constructed according to a structured protocol. A best-evidence topic was written according to a structured protocol. The question addressed was the following: in patient undergoing lung transplantation, are lungs from donors of age >60 years old (yo) associated with equivalent outcomes-including primary graft dysfunction, respiratory function and survival-than lungs from donors & LE;60yo? Altogether, >200 papers were found using the reported search, of which 12 represented the best evidence to answer the clinical question. The authors, journals, dates, country of publication, patients group studied, study type, relevant outcomes, and results of these papers were tabulated. Amongst the 12 papers reviewed, survival results were different depending on whether donor age was analysed raw or adjusted for recipients' age and initial diagnosis. Indeed, recipients with interstitial lung disease (ILD), pulmonary hypertension or cystic fibrosis (CF) had significantly inferior overall survival when receiving grafts from older donors. When older grafts are allocated to younger donors, a significant decrease in survival has been noticed in the case of single lung transplantation. In addition, 3 papers showed worse results regarding peak forced expiratory volume in 1 second (FEV1) in patients receiving older organs, and 4 showed comparable primary graft dysfunction incidence rates. We conclude that when carefully assessed and allocated to the recipient who could benefit most from the transplant (e.g., a patient with a diagnosis of chronic obstructive pulmonary disease (COPD), who would not require a prolonged cardiopulmonary bypass (CPB)), lung grafts from donors of >60yo offer comparable results to younger donors.

Automated summary

A best-evidence topic was constructed and written according to a structured protocol to address the question of whether lungs from donors above 60 years old have equivalent outcomes in lung transplant patients. Out of over 200 papers found, 12 provided the best evidence to answer this question. Results varied depending on the analysis of donor age and the recipients' age and initial diagnosis, but overall, lungs from donors above 60 years old can offer comparable results to younger donors when carefully assessed and allocated to specific recipients.
