背景资料：手术患者越来越多地使用移动的健康（mHealth）平台来监测恢复情况，并在出院后与他们的提供者进行沟通。尽管人们对移动健康有着广泛的热情，但很少有研究评估这些平台的可用性或用户体验。Objective：我们的目标是（1）开发一种用于出院后手术伤口监测的新型基于图像的智能手机应用程序，（2）使用具有代表性的血管和普外科患者人群对其进行严格的用户测试。共有9名血管和普外科住院患者对内部开发的智能手机应用程序进行了可用性测试，该应用程序允许患者拍摄伤口的数字图像，并回答有关其恢复情况的调查。我们遵循国际标准化组织（ISO）9241-11指南，专注于有效性、效率和用户满意度。同时还根据成人学习的原则制定了相应的培训模块。会议被录音，智能手机屏幕被镜像到研究计算机上。数字图像的质量进行了评估，由一个医生小组，以确定有用的临床decisionmaking.Results：所花费的平均时间长度为4.7（2.1-12.8）分钟的培训课程和5.0（1.4-16.6）分钟的应用程序完成。55.5%（5/9）的患者能够独立完成应用程序，在拍摄手术伤口的数字图像时遇到的困难最大。年龄较大、肥胖或腹股沟受伤的新手患者最困难。81.8%的图像足以用于诊断目的。用户满意度高，平均可用性得分为83.3分（满分100分）。结论：手术患者可以学习使用智能手机应用程序进行术后伤口监测，用户满意度高。我们确定了可以促进易用性的设计功能和培训方法。该协议说明了mHealth发展的一个重要但经常被忽视的方面，以改善手术护理。
Background: Surgical patients are increasingly using mobile health (mHealth) platforms to monitor recovery and communicate with their providers in the postdischarge period. Despite widespread enthusiasm for mHealth, few studies evaluate the usability or user experience of these platforms.Objective: Our objectives were to (1) develop a novel image-based smartphone app for postdischarge surgical wound monitoring, and (2) rigorously user test it with a representative population of vascular and general surgery patients.Methods: A total of 9 vascular and general surgery inpatients undertook usability testing of an internally developed smartphone app that allows patients to take digital images of their wound and answer a survey about their recovery. We followed the International Organization for Standardization (ISO) 9241-11 guidelines, focusing on effectiveness, efficiency, and user satisfaction. An accompanying training module was developed by applying tenets of adult learning. Sessions were audio-recorded, and the smartphone screen was mirrored onto a study computer. Digital image quality was evaluated by a physician panel to determine usefulness for clinical decision making.Results: The mean length of time spent was 4.7 (2.1-12.8) minutes on the training session and 5.0 (1.4-16.6) minutes on app completion. 55.5% (5/9) of patients were able to complete the app independently with the most difficulty experienced in taking digital images of surgical wounds. Novice patients who were older, obese, or had groin wounds had the most difficulty. 81.8% of images were sufficient for diagnostic purposes. User satisfaction was high, with an average usability score of 83.3 out of 100.Conclusion: Surgical patients can learn to use a smartphone app for postoperative wound monitoring with high user satisfaction. We identified design features and training approaches that can facilitate ease of use. This protocol illustrates an important, often overlooked, aspect of mHealth development to improve surgical care.
