Lung transplantation and organ allocation in Brazil: necessity or utility.

The philosophy of organ allocation is the result of two seemingly irreconcilable principles: utilitarianism and distributive justice. The process of organ donation and transplantation in Brazil reveals large inequalities between regions and units of the Federation, from the harvesting of organs to their implantation. In this context, lung transplantation is performed in only a few centers in the country and is still a treatment with limited long-term results. The allocation of the few organs harvested for the few procedures performed is defined mainly by chronology, a criterion that is not linked to necessity, which is a criterion of distributive justice, and neither to utility, a criterion of utilitarianism. This article reviews the organ allocation philosophy focusing on the case of lung transplantations in Brazil.
