Abstract

Objective: To assess the knowledge of deaf people about blood donation, before and after the application of an accessible educational video in Libras ((Brazilian Sign Language).

Method: A quasi-experimental study, conducted with 32 deaf individuals in two public institutions located in one of the states of Northeast Brazil, between June 2023 and March 2024. The data collection instrument consisted of ten questions about blood donation organized in increasing order of complexity. It was administered at three different time points: pre-test, applied before the intervention; immediate post-test, applied immediately after the intervention; and delayed post-test, applied 15 days later. Data analysis was performed using McNemar and Wilcoxon tests, considering differences significant by p≤ 0.05.

Results: A statistically significant difference was identified in the comparison of correct responses between the immediate post-test and the pre-test in three questions: appropriate moment to encourage potential donors (p=0.039), weight and age criteria for blood donation (p=0.013), and types of blood donation (p=0.012). Participants' knowledge improved significantly immediately after the intervention (p=0.010).

Conclusion: The educational video enabled deaf participants to acquire information about blood donation immediately after the educational intervention; however, this knowledge was not maintained after 15 days.

教育干预前后聋人对献血的了解。

目的：了解在天秤座（巴西手语）使用无障碍教学视频前后聋人献血知识的变化情况。方法：于2023年6月至2024年3月在巴西东北部一个州的两所公共机构对32名聋人进行准实验研究。数据收集工具由十个献血问题组成，按复杂程度从小到大排列。它在三个不同的时间点使用：前测试，在干预前应用；立即后测，干预后立即应用；延迟后测，15天后申请。数据分析采用McNemar和Wilcoxon检验，p≤0.05认为差异显著。结果：在鼓励潜在献血者的适当时机（p=0.039）、献血的体重和年龄标准（p=0.013）、献血的类型（p=0.012）三个问题上，立即后测与预测的正确回答比较，差异有统计学意义。干预后，参与者的知识水平显著提高（p=0.010）。结论：教育视频能使聋人在教育干预后立即获得献血信息；然而，15天后，这一知识并没有保持下去。
