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.
分析一段关于聋人心肺复苏知识和技能的教育视频的效果。
这是一项在三所学校进行的随机试验，共有 113 名聋人参与（对照组 57 人，干预组 56 人）。在预测试后，对照组接受讲座，而干预组则观看视频。干预后立即进行后测试，并在 15 天后重复进行。使用了一个经过验证的工具，共 11 个问题，以视频/Libras（使聋人能够理解）和书面/印刷形式呈现（记录答案）。
在知识分析中，两组在预测试中的正确答案中位数相似（p = 0.635），而干预组在即时后测试（p = 0.035）和 15 天后的测试（p = 0.026）中的准确性更高。在技能分析中，预测试中对照组的正确答案中位数更高（p = 0.031）。即时后测试（p = 0.770）没有差异，干预组在 15 天后的后测试中准确性更高（p = 0.014）。
视频在提高聋人心肺复苏知识和技能方面是有效的。巴西临床试验注册处：RBR-5npmgj。
