International Survey on Antibiotic Prophylaxis Approaches for Solid Organ Transplant Recipients and Donors Colonized With Multidrug-Resistant Organisms

Background: Multidrug-resistant organism colonization and infections cause significant morbidity and mortality in solid organ transplantation, affecting the perioperative antibiotic management. Yet, international practices for screening and antibiotic prophylaxis in colonized donors and recipients remain poorly defined. Methods: Self-administered, web-based survey conducted between February and July 2025 to assess global practices in multidrug-resistant organism screening and perioperative antibiotic management in SOT, developed by transplant infectious diseases experts and endorsed by the Transplant Infectious Diseases Section of the Transplantation Society and the European Society of Clinical Microbiology and Infectious Diseases Study Group for Infections in Compromised Hosts. Data collected included respondent and institution characteristics; screening and prophylaxis protocols; donor and recipient colonization management; and timeframes relevant for prophylaxis modification. Results: Responses from 125 tr
