PRéCIS:: In patients undergoing selective laser trabeculoplasty, preoperative video education did not improve patient knowledge regarding the procedure, decrease anxiety, or increase satisfaction, as these metrics were already favorable across all patients in this study.
To assess the effect of an educational video on patient knowledge, anxiety, and satisfaction at a selective laser trabeculoplasty (SLT) procedure visit.
This is a prospective, randomized trial. Patients at a single academic medical center completed a survey at their procedure visit for SLT; patients were randomized to view an educational video or no video before survey administration. Knowledge was assessed with a 10-item questionnaire. The 6-item State-Trait Anxiety Inventory scale (STAI-6) assessed anxiety (score >40 defined significant anxiety). Perceptions of visit quality were assessed using a Likert scale.
Twenty-two patients were randomized into video (n=11) and control (n=11) groups. No difference in knowledge was observed between groups (83.6% control vs. 82.7% video group, P=0.635). No patient had significant anxiety (STAI-6 range, 20 to 40, average 29) and scores were similar between groups (P=0.385). Overall, patients had positive perceptions of visit quality, and there was no significant difference between groups (P=0.999).
Patients undergoing SLT had high levels of knowledge, low levels of anxiety, and high levels of satisfaction. In this clinical setting, an educational video seemed to have no additional benefit on these metrics and thus, may be omitted. Further research may be directed toward optimizing patient education regarding SLT, particularly in settings with poor health literacy, limited resources, or limited access to glaucoma specialists.
评估选择性激光小梁成形术（SLT）术前观看教育视频对患者知识、焦虑和满意度的影响。
这是一项前瞻性、随机试验。单一学术医疗中心的患者在 SLT 手术就诊时完成了一项调查；患者被随机分为观看教育视频组或不观看视频组，然后进行调查。知识通过 10 项问卷评估。6 项状态特质焦虑量表（STAI-6）评估焦虑（>40 分定义为明显焦虑）。就诊质量的感知采用李克特量表评估。
22 名患者被随机分为视频（n=11）和对照组（n=11）。两组患者的知识没有差异（对照组 83.6%，视频组 82.7%，P=0.635）。没有患者出现明显焦虑（STAI-6 评分 20 至 40 分，平均 29 分），且两组间评分相似（P=0.385）。总体而言，患者对就诊质量的评价较为积极，且两组间无显著差异（P=0.999）。
接受 SLT 的患者具有较高的知识水平、较低的焦虑水平和较高的满意度。在这种临床环境下，教育视频似乎对这些指标没有额外的益处，因此可以省略。进一步的研究可以针对优化 SLT 的患者教育展开，尤其是在健康素养较差、资源有限或青光眼专家有限的情况下。
