In order to engage medical students and residents from public health centers to utilize the telemedicine features of surgery on their own smartphones and tablets as an educational tool, an innovative streaming system was developed with the purpose of streaming live footage from open surgeries to smartphones and tablets, allowing the visualization of the surgical field from the surgeon's perspective. The current study aims to describe the results of an evaluation on level 1 of Kirkpatrick's Model for Evaluation of the streaming system usage during gynecological surgeries, based on the perception of medical students and gynecology residents.
Consisted of a live video streaming (from the surgeon's point of view) of gynecological surgeries for smartphones and tablets, one for each volunteer. The volunteers were able to connect to the local wireless network, created by the streaming system, through an access password and watch the video transmission on a web browser on their smartphones. Then, they answered a Likert-type questionnaire containing 14 items about the educational applicability of the streaming system, as well as comparing it to watching an in loco procedure. This study is formally approved by the local ethics commission (Certificate No. 53175915.7.0000.5171/2016).
Twenty-one volunteers participated, totalizing 294 items answered, in which 94.2% were in agreement with the items affirmative, 4.1% were neutral, and only 1.7% answers corresponded to negative impressions. Cronbach's α was .82, which represents a good reliability level. Spearman's coefficients were highly significant in 4 comparisons and moderately significant in the other 20 comparisons.
This study presents a local streaming video system of live surgeries to smartphones and tablets and shows its educational utility, low cost, and simple usage, which offers convenience and satisfactory image resolution, thus being potentially applicable in surgical teaching.
为了让来自公共卫生中心的医学生和住院医师能够在自己的智能手机和平板电脑上利用外科手术的远程医疗功能作为一种教育工具，开发了一种创新的流媒体系统，目的是将开放手术的实时画面传输到智能手机和平板电脑上，从而让使用者能够从外科医生的视角观察手术区域。本研究旨在根据医学生和妇科住院医师的看法，描述基于柯克帕特里克评估模型一级评估的流媒体系统在妇科手术中使用情况的评估结果。
为智能手机和平板电脑提供妇科手术的实时视频流（从外科医生的视角），每位志愿者一个。志愿者能够通过访问密码连接到由流媒体系统创建的本地无线网络，并在其智能手机的网页浏览器上观看视频传输。然后，他们回答一份包含14项关于流媒体系统教育适用性的李克特式问卷，并将其与观看现场手术进行比较。本研究已获得当地伦理委员会的正式批准（证书编号53175915.7.0000.5171/2016）。
21名志愿者参与，共回答了294项内容，其中94.2%的回答为肯定，4.1%为中性，只有1.7%的回答表示负面印象。克朗巴哈系数为0.82，代表可靠性水平良好。斯皮尔曼系数在4项比较中高度显著，在其他20项比较中中度显著。
本研究展示了一种向智能手机和平板电脑传输手术直播视频的本地流媒体系统，并显示了其教育效用、低成本和使用简单的特点，该系统提供了便利性和令人满意的图像分辨率，因此有可能应用于外科教学。
