RESUMEN
BACKGROUND: Tools such as MELD score and DRI are currently used to predict risks and benefits on liver allocation for transplantation. AIM: To evaluate the relation between donor quality and recipient severity on liver allocation. METHODS: Liver transplants performed in 2017 and 2018 were evaluated. Data were collected from Paraná's State Government Registry. DRI was evaluated in relation to recipient MELD score and position on waiting list. RESULTS: It was observed relation between DRI and position on waiting list: higher risk organs were allocated to recipients with worse waiting list position. There was no relation between DRI and MELD score. Afrodescendents and elderly donor organs were allocated to lower MELD score and worse waiting list position recipients. CONCLUSION: There is no relation between DRI and MELD on liver allocation. However, DRI interferes with allocation decision based on recipients waiting list position. Donor race and age interfere on both recipient MELD score and waiting list position.

RESUMO Racional: Visando prever riscos e benefícios na alocação de órgãos no transplante hepático, são utilizados sistemas como o MELD, atual critério classificatório da lista de espera de transplantes, e o DRI, ferramenta que avalia fatores de risco do doador. Objetivo: Relacionar a qualidade do doador de fígado com a gravidade do seu receptor. Métodos: Foram avaliados os transplantes hepáticos realizados entre 2017 e 2018 no Estado do Paraná. Os dados foram coletados no sistema eletrônico da Central Estadual de Transplantes. Informações dos doadores foram relacionadas às dos receptores através da relação entre o DRI e o MELD e a posição do receptor na lista de espera. Resultados: Foram avaliados 520 doadores e 520 receptores. Observou-se relação entre DRI e posição na lista de espera: órgãos de doadores com maior risco pelo DRI foram alocados para receptores com pior posição na lista de espera. Não houve correlação entre o DRI e o MELD. No entanto, órgãos de doadores da raça negra ou com idade maior ou igual a 60 anos foram alocados para receptores com MELD mais baixo e com pior posição na lista de espera. Conclusão: Não existe relação entre o DRI e o MELD na distribuição de enxertos hepáticos no Estado do Paraná. O DRI interfere na alocação de acordo com a posição do receptor na lista de espera. A idade e a raça dos doadores interferem na alocação de acordo com o MELD e a posição em lista dos receptores.
