简要总结
This study aims to examine the effectiveness of multimedia health education in reducing preoperative anxiety and enhancing self-care awareness among patients undergoing outpatient cataract surgery. A randomized group design will be employed, in which participants will receive either standard preoperative education or a multimedia-based intervention covering surgical procedures, precautions, and postoperative care. Primary outcomes include levels of surgical anxiety, assessed using validated anxiety scales, and self-care knowledge evaluated through structured questionnaires. Findings are expected to inform the development of patient-centered educational strategies and enhance perioperative care quality in cataract surgery settings.
详细描述
This randomized controlled trial aims to evaluate the effectiveness of multimedia health education in reducing preoperative anxiety and improving postoperative care awareness among patients undergoing outpatient cataract surgery. A total of 118 patients scheduled for cataract surgery at an ophthalmology outpatient clinic will be randomly assigned to either the control group or the intervention group.
All participants will receive standard verbal preoperative instructions from their physician. In addition, the intervention group will view a 10-minute multimedia video covering the surgical procedure, precautions, and postoperative care. Baseline data-including demographics, visual acuity, physiological anxiety indicators, the Beck Anxiety Inventory (BAI), and a cataract-specific self-care knowledge questionnaire-will be collected during the final preoperative clinic visit.
Outcome data will be collected at three time points: before surgery, one week after surgery, and one month after surgery. Primary outcomes include changes in anxiety levels and self-care knowledge; secondary outcomes include physiological responses during surgery and postoperative visual recovery. The results are expected to support the use of multimedia education to enhance patient preparedness and care quality in cataract surgery.

研究组 & 干预措施
Control Group
Participants in the control group will receive standard preoperative education, including verbal explanation and printed materials about cataract surgery and postoperative care, provided by the ophthalmologist during the final clinic visit before surgery.
Multimedia Education Group
Participants in the multimedia education group will receive the same standard preoperative education as the control group, plus a 10-minute multimedia video covering the surgical procedure, preoperative instructions, postoperative care guidelines, and common patient concerns. The video includes both visual animations and spoken explanations.
干预措施: Multimedia Health Education (Behavioral)
结局指标
主要结局
Change in anxiety levels measured by the Beck Anxiety Inventory (BAI)
时间窗: Time Frame: Day 0 (baseline, preoperative clinic visit), Day of Surgery, 1 Week Postoperative, 1 Month Postoperative
Participants will complete the Beck Anxiety Inventory (BAI), a 21-item self-report questionnaire used to assess the severity of anxiety symptoms. The total score ranges from 0 to 63, with higher scores indicating greater levels of anxiety. Specifically, scores from 0-7 suggest minimal anxiety, 8-15 mild anxiety, 16-25 moderate anxiety, and 26-63 severe anxiety. The BAI will be administered at baseline and at three follow-up points.
Change in self-care knowledge related to cataract surgery
时间窗: Time Frame: Day 0 (baseline, preoperative clinic visit), Day of Surgery, 1 Week Postoperative, 1 Month Postoperative
Participants will complete a structured questionnaire designed to evaluate their knowledge of postoperative cataract care. Scores will be compared across time points to determine the impact of multimedia education.
次要结局
- Change in heart rate(Time Frame: Day 0 (baseline, preoperative clinic visit), Day of Surgery)
- Change in visual acuity following cataract surgery(Time Frame: Day 0 (baseline, preoperative clinic visit), 1 Week Postoperative, 1 Month Postoperative)
- Change in blood pressure(Day 0 (baseline, preoperative clinic visit), Day of Surgery)
