BACKGROUND & AIMS:
PURPOSE: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.
METHODS: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).
RESULTS: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.
CONCLUSIONS: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.
背景与目标:
目的:为了吸引来自公共卫生中心的医学生和居民在他们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教育工具,开发了一种创新的流媒体系统,其目的是将现场录像从开放式手术流向智能手机。和平板电脑,可以从外科医生的角度看到手术区域。本研究旨在根据医学生和妇科住院医师的看法,描述对柯克帕特里克妇科手术流系统使用率评估模型第1级的评估结果。
方法:由智能手机和平板电脑的妇科手术的实时视频流(从外科医生的角度来看)组成,每位志愿者一个。志愿者们能够通过访问密码连接到流系统创建的本地无线网络,并在智能手机的网络浏览器上观看视频传输。然后,他们回答了一个Likert型问卷,其中包含14个有关流系统的教育适用性的项目,并将其与观看本地程序进行了比较。这项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)。
结果:21名志愿者参加,总共回答294项,其中94.2%与肯定的回答相符,中立的占4.1%,只有1.7%的回答与负面印象相对应。 Cronbach的α为0.82,表示良好的可靠性水平。 Spearman系数在4个比较中高度显着,在其他20个比较中适度。
结论:本研究为智能手机和平板电脑提供了实时手术的本地流式视频系统,并显示了其教育实用性,低成本和简单易用的特点,提供了便利和令人满意的图像分辨率,因此有可能应用于外科教学。
