Organ xenotransplantation acceptance in veterinary students: A multicentric opinion study in Spain.

Background: The shortage of available transplant organs has made it necessary to search for alternatives, one of which is xenotransplantation. However, the use of animal organs could face rejection from society and the personnel involved in its implementation.

Objectives: (a) to analyze the attitudes of Veterinary Degree students in six Spanish Universities towards xenotransplantation; and (b) to determine the factors that affect its acceptance.

Methods: Of the 2815 students surveyed in the degree program, 2683 valid surveys were obtained. Attitudes towards organ xenotransplantation were evaluated using a validated questionnaire of organ donation.

Results: If xenotransplantation was confirmed as a clinical reality, 93% (n = 2493) of those surveyed would accept a xenotransplanted organ, whilst 7% would not. If the results of xenotransplantation were worse than those obtained with human donors and it entailed more risk, 12% (n = 318) would be in favor. 56% (n = 1497) of the students would accept a xenotransplantation provisionally pending the arrival of a human organ. Attitudes towards xenotransplantation were affected by the academic year in which a student was studying, with more favorable attitudes among students in the last year (88% in first year vs. 95% in fifth year; p < .001). More favorable attitudes are also observed depending on the attitude they have towards organ transplantation, with those students being more in favor of donating their organs when they die (94% vs. 88%; p < .001).

Conclusion: Veterinary students would have a very favorable attitude toward xenotransplantation if these animal organs functioned as well as human organs. Therefore, these students could play an important role in the future promotion of this technique.
