影响持续使用癌症教育元界平台的因素：混合方法研究

早期发现癌症和提供适当治疗可以提高癌症治愈率并减少癌症相关死亡。早期筛查的关键在于提升各医疗机构的筛查质量和通过针对性教育提升医护人员的能力。然而，在COVID-19疫情期间，地区间的教育基础设施差异突出，教育可及性受到限制。对远程癌症教育服务的需求增加，本研究考虑利用医疗元界作为满足这些需求的潜在手段。2022年，我们利用为医务人员虚拟培训开发的元界教育中心，远程培训放射科技术人员乳腺摄影定位技术。本研究旨在调查元界教育中心子平台的用户体验及影响其持续使用意愿的因素，特别是在远程乳腺摄影定位培训项目中的应用情况。我们在2022年7月至12月进行了一项多中心横断面调查。采用描述性分析评估用户体验，使用逻辑回归分析揭示与持续使用意愿密切相关的因素。此外，还通过开放式问题收集用户反馈，以优化元界教育中心。共收集并分析了192名韩国参与者（男性：n=16，占8.3%；女性：n=176，占91.7%）的反馈。大部分用户对元界教育中心感到满意（178/192，占92.7%）并希望未来继续使用（157/192，占81.8%）。不到一半的用户（85/192，占44.3%）在佩戴设备时没有困难。逻辑回归结果显示，持续使用意愿与满意度（调整后比值比3.542，95% CI 1.037-12.097；P=.04）、沉浸感（调整后比值比2.803，95% CI 1.201-6.539；P=.02）以及佩戴设备无困难（调整后比值比2.020，95% CI 1.004-4.062；P=.049）密切相关。而兴趣（调整后比值比0.736，95% CI 0.303-1.789；P=.50）或易用性感知（调整后比值比1.284，95% CI 0.614-2.685；P=.51）则未显示显著关系。用户反馈显示，元界教育中心在癌症教育中具有一定的实用性，但设备佩戴体验以及内容的类型和质量仍需改进。我们的结果表明，提升用户满意度和沉浸感、确保设备佩戴无困难，有助于增强用户的持续使用意愿。

Early detection of cancer and provision of appropriate treatment can increase the cancer cure rate and reduce cancer-related deaths. Early detection requires improving the cancer screening quality of each medical institution and enhancing the capabilities of health professionals through tailored education in each field. However, during the COVID-19 pandemic, regional disparities in educational infrastructure emerged, and educational accessibility was restricted. The demand for remote cancer education services to address these issues has increased, and in this study, we considered medical metaverses as a potential means of meeting these needs. In 2022, we used Metaverse Educational Center, developed for the virtual training of health professionals, to train radiologic technologists remotely in mammography positioning.This study aims to investigate the user experience of the Metaverse Educational Center subplatform and the factors associated with the intention for continuous use by focusing on cases of using the subplatform in a remote mammography positioning training project.We conducted a multicenter, cross-sectional survey between July and December 2022. We performed a descriptive analysis to examine the Metaverse Educational Center user experience and a logistic regression analysis to clarify factors closely related to the intention to use the subplatform continuously. In addition, a supplementary open-ended question was used to obtain feedback from users to improve Metaverse Educational Center.Responses from 192 Korean participants (male participants: n=16, 8.3%; female participants: n=176, 91.7%) were analyzed. Most participants were satisfied with Metaverse Educational Center (178/192, 92.7%) and wanted to continue using the subplatform in the future (157/192, 81.8%). Less than half of the participants (85/192, 44.3%) had no difficulty in wearing the device. Logistic regression analysis results showed that intention for continuous use was associated with satisfaction (adjusted odds ratio 3.542, 95% CI 1.037-12.097; P=.04), immersion (adjusted odds ratio 2.803, 95% CI 1.201-6.539; P=.02), and no difficulty in wearing the device (adjusted odds ratio 2.020, 95% CI 1.004-4.062; P=.049). However, intention for continuous use was not associated with interest (adjusted odds ratio 0.736, 95% CI 0.303-1.789; P=.50) or perceived ease of use (adjusted odds ratio 1.284, 95% CI 0.614-2.685; P=.51). According to the qualitative feedback, Metaverse Educational Center was useful in cancer education, but the experience of wearing the device and the types and qualities of the content still need to be improved.Our results demonstrate the positive user experience of Metaverse Educational Center by focusing on cases of using the subplatform in a remote mammography positioning training project. Our results also suggest that improving users' satisfaction and immersion and ensuring the lack of difficulty in wearing the device may enhance their intention for continuous use of the subplatform.
