To analyze the effectiveness of an educational video on deaf people's knowledge and skills about cardiopulmonary resuscitation.
A randomized trial, carried out at three schools with 113 deaf people (control group = 57 and intervention group = 56). After the pre-test, the control group was exposed to the lecture, while the intervention group was exposed to the video. The post-test occurred immediately after the intervention and was repeated after 15 days. A validated instrument was used, with 11 questions, presented in video/Libras (to enable understanding by deaf people) and in written/printed form (to record the answers).
In the analysis of knowledge, the median of correct answers in the pre-test was similar between the groups (p = 0.635), while the intervention group had a higher accuracy in the immediate post-test (p = 0.035) and after 15 days (p = 0.026). In the skill analysis, the median of correct answers in the pre-test was higher in the control group (p = 0.031). There was no difference in the immediate post-test (p = 0.770), and there was a higher accuracy in the intervention group in the post-test after 15 days (p = 0.014).
The video proved to be effective in increasing deaf people's knowledge and skills about cardiopulmonary resuscitation. Brazilian Registry of Clinical Trials: RBR-5npmgj.
