Abstract

Background Mobile health has promising potential in improving healthcare delivery by facilitating access to expert advice. Enabling experts to review images on their smartphone or tablet may save valuable time. This study aims at assessing whether images viewed by medical specialists on handheld devices such as smartphones and tablets are perceived to be of comparable quality as when viewed on a computer screen. Methods This was a prospective study comparing the perceived quality of 18 images on three different display devices (smartphone, tablet and computer) by 27 participants (4 burn surgeons and 23 emergency medicine specialists). The images, presented in random order, covered clinical (dermatological conditions, burns, ECGs and X-rays) and non-clinical subjects and their perceived quality was assessed using a 7-point Likert scale. Differences in devices' quality ratings were analysed using linear regression models for clustered data adjusting for image type and participants’ characteristics (age, gender and medical specialty). Results Overall, the images were rated good or very good in most instances and more so for the smartphone (83.1%, mean score 5.7) and tablet (78.2%, mean 5.5) than for a standard computer (70.6%, mean 5.2). Both handheld devices had significantly higher ratings than the computer screen, even after controlling for image type and participants' characteristics. Nearly all experts expressed that they would be comfortable using smartphones (n=25) or tablets (n=26) for image-based teleconsultation. Conclusion This study suggests that handheld devices could be a substitute for computer screens for teleconsultation by physicians working in emergency settings.
使用智能手机或平板电脑的基于图像的远程咨询:医学专家的定性评估
背景:移动医疗通过促进获得专家建议,在改善医疗保健服务方面具有很大的潜力。让专家在他们的智能手机或平板电脑上查看图像可能会节省宝贵的时间。这项研究旨在评估医学专家在智能手机和平板电脑等手持设备上观看的图像是否与在电脑屏幕上观看的图像质量相当。方法前瞻性研究比较27名受试者(4名烧伤外科医生和23名急诊医学专家)在3种不同显示设备(智能手机、平板电脑和电脑)上的18幅图像的感知质量。随机呈现的图像涵盖临床(皮肤病、烧伤、心电图和x射线)和非临床受试者,并使用7分李克特量表评估其感知质量。使用聚类数据的线性回归模型对图像类型和参与者特征(年龄、性别和医学专业)进行调整,分析设备质量评级的差异。总体而言,在大多数情况下,智能手机(83.1%,平均得分5.7)和平板电脑(78.2%,平均5.5)的图像被评为好或非常好,而标准电脑(70.6%,平均5.2)的图像则被评为好或非常好。即使在控制了图像类型和参与者的特征之后,这两种手持设备的评分都明显高于电脑屏幕。几乎所有的专家都表示,他们愿意使用智能手机(25人)或平板电脑(26人)进行基于图像的远程咨询。结论:本研究表明,手持设备可以替代计算机屏幕,用于医生在紧急情况下的远程会诊。
