Head and neck radiotherapy can cause several toxicities, and its management has important treatment implications. Proper information about treatment is crucial to assist patients by preparing them and enhancing their ability to manage their illness. Thus, this study aimed to verify the impact of an educational video on the improvement of the patient's understanding, satisfaction, quality of life, and influence on their emotional state in different moments of treatment.
A 10 min video about head and neck radiotherapy and its toxicities was produced. A prospective randomized clinical trial was performed in two groups: a control group (n = 65), which received standard verbal and written information, and an experimental group (n = 65), which received standard information and the video. Appropriated questionnaires (HADS, UW-QOLv4, IRTU, and Post-RTU) were applied in four different moments in order to evaluate patients' understanding, anxiety, depression, and quality of life.
The video improved the understanding of treatment and its side effects. Also, the video group reported better awareness about oral health care during the treatment. Osteoradionecrosis and radiation-related caries were the most unknown side effects. On the other hand, the educational video did not modify the patients' anxiety, depression, and quality of life. All patients reported high satisfaction with the video.
Audiovisual tools may improve patients' understanding of radiotherapy and were shown to be a useful tool when used in association with verbal and written information in cancer centers. In addition, information about osteoradionecrosis and radiation-related caries must be reinforced to patients.
头颈部放射治疗可引起多种毒性反应，其管理对治疗具有重要意义。适当的治疗信息对于帮助患者非常重要，包括使他们做好准备并提高其管理疾病的能力。因此，本研究旨在验证教育视频对改善患者在治疗不同阶段的理解、满意度、生活质量和对其情绪状态的影响。
制作了一个关于头颈部放射治疗及其毒性的 10 分钟视频。在两组患者中进行了一项前瞻性随机临床试验：对照组（n=65）接受标准的口头和书面信息，实验组（n=65）接受标准信息和视频。在四个不同的时间点使用适当的问卷（HADS、UW-QOLv4、IRTU 和 Post-RTU）评估患者的理解、焦虑、抑郁和生活质量。
视频提高了对治疗及其副作用的理解。此外，视频组在治疗期间报告了更好的口腔保健意识。放射性骨坏死和辐射相关龋齿是最不为人知的副作用。另一方面，教育视频并未改变患者的焦虑、抑郁和生活质量。所有患者对视频的满意度均很高。
视听工具可以提高患者对放射治疗的理解，并且在癌症中心与口头和书面信息一起使用时，是一种有用的工具。此外，必须向患者强化放射性骨坏死和辐射相关龋齿的信息。
