背景资料：人类免疫缺陷病毒自我检测（HIVST）减少了与基于设施的检测相关的障碍;然而，没有正式的机制供用户自我报告结果或与护理联系。Aspect（TM）HIVST移动的应用程序（app）是为在南非使用而开发的。Objectives：本研究评估了Aspect（TM）HIVST应用程序对来自Johannesburg.Method市中心的个人的可接受性和可行性。向参与者提供OraQuick HIVST试剂盒和预装了应用程序的智能手机，然后要求他们按照应用程序内的使用说明书（IFU）完成HIVST并上传结果。经过培训的医护人员（HCW）观察并记录了与IFU的任何偏离，并进行了测试后调查以评估可接受性。通过同意参与、完成自我测试并将所有信息正确上传到应用程序的参与者数量来评估可行性。结果：大多数参与者（98.7%）认为应用程序易于使用。为了减少与IFU相关的困难（26; 8.7%），参与者建议多媒体补充（4; 1.3%），其他语言（4; 1.3%）和简化说明（5; 1.7%）。所有参与者都同意参与，267人（89.0%）正确完成了所有步骤，210人（78.7%）成功捕获了应用程序上的所有信息。大多数错误（26; 8.7%）是测试错误，1个（0.3%）来自应用程序序列。12例（4.5%）错误与试纸成像和72（27.0%）不一致与人口统计学信息。结论：尽管使用说明书解释和通过应用程序采集数据存在一些挑战，但该试点表明，Aspect（TM）HIVST应用程序是一种可接受的方式，可以将移动的HIVST结果和人口统计学信息上传到中央数据库。
Background: Human immunodeficiency virus self-testing (HIVST) reduces barriers associated with facility-based testing; however, no formal mechanism exists for users to self-report results or link to care. The Aspect (TM) HIVST mobile application (app) was developed for use in South Africa.Objectives: This study evaluated the acceptability and feasibility of the Aspect (TM) HIVST app for individuals from the inner city of Johannesburg.Method: This cross-sectional pilot, with a convenience sample of 300 adults, was conducted in July 2018. Participants were provided an OraQuick HIVST kit and a smartphone preloaded with the app, then asked to follow the in-app instructions for use (IFU) to complete the HIVST and upload results. Trained healthcare workers (HCWs) observed and recorded any deviations from the IFU, and conducted a post-test survey to assess acceptability. Feasibility was evaluated by the number of participants who agreed to participate, completed the self-test, and uploaded all information onto the app correctly.Results: Most participants (98.7%) found the app easy to use. To reduce difficulties related to the IFU (26; 8.7%), participants suggested multimedia supplements (4; 1.3%), additional languages (4; 1.3%) and simplified instructions (5; 1.7%). All individuals approached, agreed to participate, 267 (89.0%) correctly completed all steps and 210 (78.7%) successfully captured all information on the app. Most errors (26; 8.7%) were testing errors and 1(0.3%) was from the app sequence. Twelve (4.5%) errors were with test strip imaging and 72 (27.0%) discordances were with demographic information.Conclusion: Despite some challenges with IFU interpretation and data capture via the app, this pilot showed that the Aspect (TM) HIVST app is an acceptable way to upload mobile HIVST results and demographic information to a central database.
