Knowledge of the Concept of Brain Death Among the Latin-American Population Residing in Spain

The knowledge of brain death is fundamental for being able to understand the organ donation process and for ensuring its acceptance or rejection. Here, we analyzed the level of knowledge of the concept of brain death among Latin-American individuals who are residents of Spain to determine the factors affecting this knowledge.

Our patient group was a sample of 1314 Latin-American residents of Spain, obtained randomly and stratified according to the respondent's nationality, age, and sex. Their attitude was assessed using a validated questionnaire. The survey was self-administered and completed anonymously.

The questionnaire completion rate was 94% (n = 1237). Of total respondents, 25% (n = 313) knew the concept of brain death, which they considered to be an individual's death, 56% (n = 697) did not know the term, and 19% (n = 227) believed that it did not mean death. The variables related to knowledge of the brain death concept included (1) country of origin, with a better knowledge among those with Mexican nationality (P < .001); (2) male sex (30% vs 23%; P = .003); (3) having university-level education (35% vs 23%; P = .044); (4) having discussed the matter within the family (29% vs 23%; P = .044); (5) having a partner with a favorable attitude toward donation (39% vs 21%; P = .001); and (6) the respondent's religion (47% vs 7%; P < .001). The following factors persisted in the multivariate analysis: country of origin (odds ratio of 2.972), sex (odds ratio of 1.416), education level (odds ratio of 2.228), attitude of the respondent's partner (odds ratio of 1.835), and religion (odds ratio of 4.490).

Knowledge of the concept of brain death is limited among Latin-American residents of Spain, with marked differences among country of origin and other socio-personal factors.
