To investigate the usability of Mixed-Reality (MR) during patient education in patients scheduled for abdominal aortic aneurysm (AAA) repair. Consecutive patients scheduled for elective AAA repair were block-randomized in either the Mixed-Reality group (MR group) or the conventional group (control group). Patients of both groups were educated about open and endovascular repair of their respective AAA. The MR group was educated using a head-mounted display (HMD) demonstrating a three-dimensional virtual reconstruction of the respective patient's vascular anatomy. The control group was educated using a conventional two-dimensional monitor to display the patient's vasculature. Outcomes were informational gain as well as patient satisfaction with the educational process. (DRKS-ID: DRKS00025174). 50 patients were included with 25 patients in either group. Both groups demonstrated improvements in scores in the Informational Gain Questionnaire (IGQ) when comparing pre- and post-education scores. (MR group: 6.5 points (±1.8) versus 7.9 points (±1.5); Control group: 6.2 points (±1.8) versus 7.6 points (±1.6); p<0.01) There was no significant difference between the MR group and the control group either in informational gain (MR group: 1.4±1.8; Control group: 1.4±1.8; p=0.5) nor in patient satisfaction scores (MR group: mean 18.3 of maximum 21 points (±3.7); Control group: mean 17 of 21 points (±3.6); p=0.1) Multiple regression revealed no correlation between the use of MR and informational gain or patient satisfaction. Usability of the system was rated high, and patients' subjective assessment of MR was positive. The use of MR in patient education of AAA patients scheduled for elective repair is feasible. While patients reported positively on the use of MR in education, similar levels of informational gain and patient satisfaction can be achieved with MR and conventional methods.
为了调查混合现实（MR）在计划接受腹主动脉瘤（AAA）修复的患者的患者教育中的可用性。连续计划接受择期 AAA 修复的患者按混合现实组（MR 组）或常规组（对照组）进行分组。两组患者均接受有关开放和血管内修复各自 AAA 的教育。MR 组使用头戴式显示器（HMD）接受教育，该显示器演示了各自患者血管解剖结构的三维虚拟重建。对照组使用常规二维显示器来显示患者的血管。结果是信息增益以及患者对教育过程的满意度。（DRKS-ID：DRKS00025174）。共纳入 50 例患者，每组 25 例。两组在比较教育前后的分数时，信息增益问卷（IGQ）的分数均有所提高。（MR 组：6.5 分（±1.8）与 7.9 分（±1.5）；对照组：6.2 分（±1.8）与 7.6 分（±1.6）；p<0.01）MR 组与对照组之间在信息增益方面没有差异（MR 组：1.4±1.8；对照组：1.4±1.8；p=0.5）或患者满意度评分（MR 组：最大 21 分的平均 18.3 分（±3.7）；对照组：21 分的平均 17 分（±3.6）；p=0.1）。多元回归显示，MR 的使用与信息增益或患者满意度之间没有相关性。系统的可用性得到了高度评价，并且患者对 MR 的主观评估是积极的。在计划接受择期修复的 AAA 患者的患者教育中使用 MR 是可行的。虽然患者报告了在教育中使用 MR 的积极作用，但使用 MR 和常规方法可以获得相似水平的信息增益和患者满意度。
