Access to information about tuberculosis (TB) is vital to ensure timely diagnosis, treatment, and control among vulnerable communities. Improved approaches for distributing health education materials to remote populations are needed. To evaluate the impact of two comprehensive video training curricula in improving patient, community member, and community health worker knowledge of TB in a remote area of Madagascar. A pre-test/post-test design was used to measure knowledge acquisition. Educational videos were short, culturally appropriate films presented at critical moments in the TB cascade of care. Of the total 146 participants, 86 (58.9%) improved their score on the post-test, 50 (34.2%) obtained the same score, and 10 (6.8%) received a worse score. A statistically significant difference was observed between the pre- and post-test scores, wherein scores increased by a median of 10.0% (interquartile range 0.0-20.0) after viewing the videos ( < 0.001). There was a significant difference between the number of correct answers on the pre-test and the number of correct answers on the post-test ( < 0.001). Educational videos were found to significantly improve TB knowledge among a low-literacy, remote population in Madagascar. Our findings suggest educational videos could be a powerful, low-cost, and sustainable tool to improve access to TB education materials globally.
获取结核病 (TB) 信息对于确保脆弱社区的及时诊断、治疗和控制至关重要。需要改进向偏远地区人群分发健康教育材料的方法。评估两种综合视频培训课程在马达加斯加偏远地区提高患者、社区成员和社区卫生工作者对结核病知识的影响。采用预测试/后测试设计来衡量知识获取。教育视频是在结核病护理级联的关键时刻呈现的简短、文化适宜的电影。在总共 146 名参与者中，86 名（58.9%）在后测中提高了分数，50 名（34.2%）获得相同分数，10 名（6.8%）获得更差分数。在预测试和后测试分数之间观察到统计学上的显著差异，其中观看视频后分数中位数增加了 10.0%（四分位距 0.0-20.0）（<0.001）。预测试的正确答案数量与后测试的正确答案数量之间存在显著差异（<0.001）。教育视频被发现可显著提高马达加斯加低识字率偏远地区的结核病知识。我们的研究结果表明，教育视频可能是一种强大、低成本和可持续的工具，可以改善全球获取结核病教育材料的机会。
