Impact of Culture of Perfusion Fluid on Donor-derived Infection Management and Outcome in Liver and Kidney Transplant

This study aims to evaluate whether microbiological testing of the perfusion fluid used to transport transplanted organs can help predict the development of infections in liver and kidney transplant recipients, including possible donor-derived infections (infections transmitted from the donor organ). The study will include all liver and kidney transplant recipients with available perfusion fluid culture results from 2021 until the start of the study (retrospective phase) and for two years after study initiation (prospective phase). The study will assess how often high-risk microorganisms are identified in perfusion fluid, whether these findings are associated with complications or infections in recipients, and whether they affect patient outcomes, including mortality.

Inclusion Criteria: * Adult patients (≥18 years old) undergoing liver or kidney transplantation at IRCCS AOUBO clinical center during the specified study periods * Availability of graft preservation fluid culture results * Signed informed consent Exclusion Criteria: * None
