Abstract
Objective: Evaluate the knowledge and acceptance of the Brazilian population on the diagnosis of brain death (BD) and organ and tissue donation for transplants. Methods: This is a descriptive, cross-sectional observational study, carried out for convenience, through the application of an online questionnaire, through the Google Forms® Platform, with questions based on the regulatory laws on organ and tissue donation for transplants in Brazil. Results: 406 subjects participated in the survey, with a predominance of females (73.60%), aged between 18 and 30 years (45.80%), attending higher education (33.20%) and self-declared Catholics (35.40%). Of the total, (93.10%) of the participants declared themselves in favor of donation, despite (71.10%) believing that there is a sale of organs and tissues. Conclusion: Campaigns and information on the subject should be intensified, containing clear and objective information, to elucidate the population on the subject, thus seeking to increase the number of effective donors in the country.
