Sin Duda: a community-driven approach to expand reach, access and uptake of COVID-19 home-based tests for at risk Latinos

新冠肺炎疫情对美国拉丁裔的影响不成比例。新冠肺炎测试对 跟踪和减缓病毒的传播，预防今后的疫情，特别是在社区中 受新冠肺炎影响不成比例，疫苗接种率低于最佳水平。这样做的目的是 该项目是扩大我们的RADx-UP第一阶段新冠肺炎测试项目“万寿无忧”，以实施和 评估创新的实施战略，以增加马里兰州低收入拉美裔美国人对新冠肺炎家庭自测的覆盖率、访问率和接受度。我们将实施和评估两种COVID19 HST分销方式：1)基于网络的；2)社交营销。我们还将纳入数据驱动的迭代更改，以优化社区卫生工作者(CHW)领导的短消息服务(SMS) 支持卫生保健技术的平台以及与新冠肺炎护理、疫苗接种和其他服务(例如，现金和食品)的链接 协助)。主要和次要结果包括：1)HST的到达和吸收；2)与护理的联系 对于那些检测呈阳性的人或为那些检测呈阴性的未接种疫苗的人接种疫苗。利用我们现有的 在社区联盟、检测和疫苗接种诊所以及一支由双语和双文化社区卫生工作者组成的团队的帮助下，我们已经做好了实施新冠肺炎HST计划并衡量其影响的准备。我们的研究将提供重要的 新信息将改善对创新新冠肺炎测试技术的获取和吸收。它也会填满 关键知识差距，以指导将循证干预措施转化为广泛采用 RADx-UP联盟成员。

The COVID-19 pandemic disproportionately impacts Latinos in the US. COVID-19 testing remains critical for tracking and slowing the spread of the virus and preventing future outbreaks, particularly in communities disproportionately affected by COVID-19 and where vaccination coverage is suboptimal. The goal of this project is to expand our RADx-UP Phase 1 COVID-19 testing project "Vive Sin Duda" to implement and evaluate innovative implementation strategies to increase reach, access, and uptake of COVID-19 homebased self-testing (HST) among low-income Latinos in Maryland. We will implement and evaluate two COVID19 HST distribution approaches: 1) Network-based; and 2) Social marketing. We will also incorporate data driven iterative changes to optimize a community health worker (CHW)-led short message service (SMS) platform to support HST and linkage to COVID-19 care, vaccination, and other services (e.g., cash and food assistance). Primary and secondary outcomes include: 1) Reach and uptake of HST; and 2) Linkage to care for those who test positive or vaccination for unvaccinated people who test negative. Leveraging our existing community coalition, testing and vaccination clinics, and a team of bilingual and bicultural CHWs, we are well poised to implement a COVID-19 HST program and measure its impact. Our research will provide important new information that will improve access and uptake of innovative COVID-19 testing technology. It also will fill critical knowledge gaps to guide the translation of evidence-based interventions into widespread adoption by RADx-UP consortium members.
