The response to the 2014-2016 Ebola epidemic included an unprecedented effort from federal, state, and local public health authorities to monitor the health of travelers entering the United States from countries with Ebola outbreaks. The Check and Report Ebola (CARE) Hotline, a novel approach to monitoring, was designed to enable travelers to report their health status daily to an interactive voice recognition (IVR) system. The system was tested with 70 Centers for Disease Control and Prevention (CDC) federal employees returning from deployments in outbreak countries.
The objective of this study was to describe the development of the CARE Hotline as a tool for postarrival monitoring and examine the usage characteristics and user experience of the tool during a public health emergency.
Data were obtained from two sources. First, the CARE Hotline system produced a call log which summarized the usage characteristics of all 70 users' daily health reports. Second, we surveyed federal employees (n=70) who used the CARE Hotline to engage in monitoring. A total of 21 (21/70, 30%) respondents were included in the survey analytic sample.
While the CARE Hotline was used for monitoring, 70 users completed a total of 1313 calls. We found that 94.06% (1235/1313) of calls were successful, and the average call time significantly decreased from the beginning of the monitoring period to the end by 32 seconds (Z score=-6.52, P<.001). CARE Hotline call log data were confirmed by user feedback; survey results indicated that users became more familiar with the system and found the system easier to use, from the beginning to the end of their monitoring period. The majority of the users were highly satisfied (90%, 19/21) with the system, indicating ease of use and convenience as primary reasons, and would recommend it for future monitoring efforts (90%, 19/21).
The CARE Hotline garnered high user satisfaction, required minimal reporting time from users, and was an easily learned tool for monitoring. This phone-based technology can be modified for future public health emergencies.
对2014 - 2016年埃博拉疫情的应对措施包括联邦、州和地方公共卫生当局做出前所未有的努力，以监测从有埃博拉疫情爆发的国家进入美国的旅行者的健康状况。“检查与报告埃博拉”（CARE）热线是一种新颖的监测方法，旨在使旅行者能够每天向交互式语音识别（IVR）系统报告自己的健康状况。该系统在70名从疫情爆发国家部署任务归来的疾病控制与预防中心（CDC）联邦雇员中进行了测试。
本研究的目的是描述CARE热线作为一种抵达后监测工具的开发过程，并考察该工具在公共卫生紧急事件期间的使用特征和用户体验。
数据来自两个来源。首先，CARE热线系统生成了一个通话记录，总结了所有70名用户每日健康报告的使用特征。其次，我们对使用CARE热线进行监测的联邦雇员（n = 70）进行了调查。共有21名（21/70，30%）受访者被纳入调查分析样本。
在使用CARE热线进行监测期间，70名用户共完成了1313次通话。我们发现94.06%（1235/1313）的通话成功，并且从监测期开始到结束，平均通话时间显著减少了32秒（Z分数 = -6.52，P <.001）。CARE热线通话记录数据得到了用户反馈的证实；调查结果表明，从监测期开始到结束，用户对系统越来越熟悉，并且发现系统更易于使用。大多数用户（90%，19/21）对该系统高度满意，将易用性和便利性作为主要原因，并表示会推荐该系统用于未来的监测工作（90%，19/21）。
CARE热线获得了用户的高度满意度，用户报告时间最少，是一种易于掌握的监测工具。这种基于电话的技术可针对未来的公共卫生紧急事件进行改进。
