Educational Videos for Thyroid Surgery Patient

• Thyroid Surgery Educational Video (Other): Accepting educational video on postoperative TSH suppression therapy for differentiated thyroid cancer created by researchers based on guidelines

Primary outcomes

• TSH Compliance Rate [Postoperative Month 1, Postoperative Month 3, Postoperative Month 6, and Postoperative Month 12]: The criteria for determining the TSH target achievement rate are based on a combination of three factors: the patient's postoperative recurrence risk stratification, the follow-up time point, and the current TSH test result. Within one year postoperatively, the TSH suppression targets are < 0.1 mU/L for the high-risk group, 0.1-0.5 mU/L for the moderate-risk group, and 0.1-0.5 mU/L (low Tg) or 0.5-2 mU/L (undetectable Tg, lobectomy) for the low-risk group. In statistical analysis, the TSH target range attainment rate = (number of patients with TSH levels within the target range at each follow-up time point / total number of patients followed up at that time point) × 100%
• Patient satisfaction [Immediately after the educational presentation (post-intervention)]: Patient satisfaction following different educational approaches was assessed using a 5-point Likert scale (1-5 scale; the higher the score, the higher the satisfaction).

Secondary outcomes

• Level of knowledge dissemination [Postoperative Month 1, Postoperative Month 3, Postoperative Month 6, and Postoperative Month 12]: Knowledge assessment consists of 6 multiple-choice questions, 2 true/false questions, and 2 fill-in-the-blank questions to evaluate patients' understanding and awareness of educational topic.
• Patient anxiety level [Baseline (before the educational outreach) and immediately after the educational outreach; two assessments total]: Anxiety scale, thereby assessing the patient's level of anxiety. A 5-point Likert scale was used, with each item scored on a scale of 1 to 5, ranging from "not at all" to "very severe."
• Patient's Level of Regret After Surgery [Baseline (before the educational outreach) and immediately after the educational outreach]: Regret Scale, thereby recording the patient's degree of postoperative regret. 1. This was the right decision. 2\. I regret making this choice. 3. If I had the chance to do it over, I would make the same choice. 4. This choice caused me a lot of pain. 5. This was a wise decision. A 5-point Likert scale was used, with each item scored on a scale of 1 to 5; the lower the score, the less regret the respondent felt.
• Incidence of adverse events in patients [Postoperative Month 1, Postoperative Month 3, and Postoperative Month 6]: Whether the patient has forgotten to take medication or mistakenly recorded the follow-up appointment time, etc.
