RESUMEN
OBJECTIVES: To assess, among medical students, the willingness to donate their own organs or those of a family member, and to establish reasons for refusal. MATERIALS AND METHODS: During the 2016 academic year, an anonymous survey was conducted among University of Buenos Aires School of Medicine second-year students. RESULTS: Of the total 1012 respondents, 81.92% would agree to donate and 18.08% would not. Thirty two percent would not authorize donation of a family member's organ. Almost all (94.1%) students reported they had little information about organ donation. Reasons for refusal included: fears about the possibility of not being really dead when considered for organ ablation (36.4%); lack of confidence in (25.8%) or lack of information about the organ procurement and transplantation system (14.6%); no interest in organ donation (9.3%); and religious reasons (6%). Brain death was considered irreversible by 59.7% of donors and by only 51% of non-donors (P = .036). Contact with a transplanted person was more frequent in the donor group (30.9% vs 21.3%, P = .01). More donors were found among the group who discussed the subject with their families than among the group who did not (69.1% vs 62.9%, P = .053). CONCLUSIONS: A considerable percentage of medical school students would not be willing to donate their own or a family member's organs. Main reasons are mistrust of the system, lack of information about donation programs, and poor understanding of the brain death concept. Contact with an organ recipient and discussing the subject in the family both favored donation.
