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

2019冠状病毒病大流行对美国的拉丁裔造成了不成比例的影响。COVID-19检测仍然至关重要， 追踪和减缓病毒的传播，防止未来爆发疫情，特别是在社区 受COVID-19影响不成比例且疫苗接种覆盖率不理想的地区。这个目标 项目是扩大我们的RADx-UP第一阶段COVID-19测试项目“Vive Sin杜达”，以实施和 评估创新的实施战略，以增加马里兰州低收入拉丁美洲人对COVID-19家庭自我检测（HST）的覆盖、获取和使用。我们将实施和评估两种COVID 19 HST分发方法：1）基于网络; 2）社会营销。我们还将纳入数据驱动的迭代变化，以优化社区卫生工作者（CHW）主导的短消息服务（SMS） 支持HST和与COVID-19护理、疫苗接种和其他服务（例如，现金和粮食 援助）。主要和次要结果包括：1）HST的覆盖和吸收;以及2）与护理的联系 对于那些测试呈阳性或接种疫苗的人谁测试阴性。利用我们现有的 社区联盟，检测和疫苗接种诊所，以及一个双语和双文化的CHW团队，我们已经做好了实施COVID-19 HST计划并衡量其影响的准备。我们的研究将提供重要的 新的信息将改善创新的COVID-19检测技术的获取和采用。它也将填补 关键的知识差距，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.
