Introduction:

In Chile, the first transplant was performed in 1967, since then, many efforts have been made to motivate the population to become a donor. At first, this measure brought positive results, but in recent years it has been observed a regression and stagnation in the pro-donation attitude.

Objective:

To verify the effect of an educational intervention on the attitude about organ donation in students between 8th grade primary school and 2nd grade secondary school from the ‘Fundacion Educacional Santa Bernardita’ school of Talcahuano, during the year 2017.

Material and Method:

Quantitative study, of quasi-experimental design (before-after). The sample was non-probabilistic obtained by quotas. The questionnaire that measures attitude to donation and sociodemographic questions before and after the educational sessions were used.

Results:

The sample consisted on 136 participants, with an average age of 14 years, 75% profess a religion, 42% belong to medium-low class. Before the educative intervention, 77% showed a negative attitude towards donation and after the intervention, the number decreased to 59.6%, being statistically significant.

Conclusions:

It was concluded that the educational intervention generated positive changes in response to the attitude of donating in this population, so it is suggested to replicate this methodology in other educational centers in the region and at the national level, which could generate an increase in the number of donors in Chile.
