简要总结
This randomized comparative trial evaluated whether an animated educational video, added to standard verbal counselling, differs from a content-matched written information leaflet, also added to standard verbal counselling, in improving procedural knowledge and reducing preoperative anxiety among adult kidney transplant candidates and prospective living donors. Participants were assessed immediately before and immediately after the assigned intervention. Secondary outcomes included participant satisfaction, preferred information modality, and the understandability and actionability of the educational materials.
详细描述
Adult kidney transplant candidates undergoing preoperative evaluation and their prospective living donors were randomly allocated 1:1 to a video group or a written group. Both groups received standardized verbal counselling, unchanged across arms; the video group additionally viewed a ~2.5-minute animated video, and the written group additionally read a content-matched, illustrated A4 leaflet covering the same kidney transplant surgical pathway (laparoscopic live donor nephrectomy, bench surgery, and recipient stages). Procedural knowledge was measured with a seven-item investigator-developed questionnaire and preoperative anxiety with the validated Turkish Amsterdam Preoperative Anxiety and Information Scale (APAIS), administered immediately before and after the intervention. After the post-test, participants were cross-over exposed to the other format and indicated their preferred modality for future education. The understandability and actionability of both materials were independently rated using the Patient Education Materials Assessment Tool (PEMAT-A/V and PEMAT-P).

结局指标
主要结局
Change in procedural knowledge
时间窗: Day 1 (immediately before and immediately after the intervention, same study visit)
Procedural knowledge was measured with a 7-item investigator-developed multiple-choice Kidney Transplant Surgical Process Knowledge Questionnaire, scored as the number of incorrect responses. Scores range from a minimum of 0 to a maximum of 7. Higher scores indicate worse knowledge (more incorrect answers); a decrease from pre- to post-test indicates a better outcome.
Change in preoperative anxiety with the Amsterdam Preoperative Anxiety and Information Scale (APAIS) score
时间窗: Day 1 (immediately before and immediately after the intervention, same study visit)
Preoperative anxiety and information need were measured with the Amsterdam Preoperative Anxiety and Information Scale (APAIS), total score. Scores range from a minimum of 6 to a maximum of 30. Higher scores indicate a worse outcome (greater anxiety and information need); a decrease from pre- to post-test indicates a better outcome.
次要结局
- Post-intervention knowledge score (between groups)(Day 1 (immediately after the intervention, same study visit))
- Post-intervention Amsterdam Preoperative Anxiety and Information Scale (APAIS) score (between groups)(Day 1 (immediately after the intervention, same study visit))
- Participant satisfaction(Day 1 (immediately after the intervention, same study visit))
- Preferred information modality(Day 1 (immediately after interventions and cross-over exposure to both formats, same study visit))
- Understandability of the educational materials, assessed with the Patient Education Materials Assessment Tool (PEMAT) score(Baseline (educational materials assessed prior to participant enrollment))
