REDES: a peer network and mobile health (mHealth) enhanced CHW model to maximize COVID-19 vaccination among low income Latinos

项目摘要 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。未能提供平等的机会， 疫苗将加剧拉丁美洲人在COVID-19和其他健康状况方面的巨大差距 社区.我们的团队已经建立了一个社区联盟，并确定了有效的干预措施，以减少 低收入有限的英语能力（LEP）拉丁美洲社区之间的差距，使用定性，调查， 和实施科学方法。我们将测试联合干预REDES （“网络”）--一种社交网络和移动的健康（mHealth）增强型社区卫生工作者（CHW） 干预-以解决COVID-19疫苗的犹豫和一群拉丁美洲人及其 马里兰州的网络。我们将招募300名已接种COVID-19疫苗的指数参与者。半年 指数参与者将被随机分配到实验组（n=150）。CHW将训练他们成为同龄人 导师亲自和通过短信进行同行外联，并促进疫苗的接受， 通过他们的网络。对照组（n=150）中的指数受试者将获得同等关注 干预此外，我们将招募未接种疫苗的主要和次要网络成员的索引， 研究参与和COVID-19疫苗接种。我们将招收估计总数为1，590小学和 二级网络成员。所有参与者将在术后3、6、12和18个月进行前瞻性随访。 基线摄入量。具体目标是：1）评价联合干预REDES的有效性， 促进拉丁美洲人的COVID-19疫苗接种; 2）检查疫苗的持续障碍和促进因素 拉丁美洲人及其网络的吸收，以调整我们的干预措施和应对新的挑战，以及3） 评价REDES的实施决定因素和成果，为今后的大规模 实施.我们的多学科研究团队汇集了拉丁裔健康，社交网络，移动健康 干预措施、疫苗犹豫专门知识;社区与合作伙伴长期合作历史 组织在马里兰州;和现有的双语/双文化CHW能力和丰富的地方基础设施， COVID-19应对措施。如果这种联合干预证明了疗效，我们将开发一种 为社区伙伴和卫生部门提供英文和西班牙文的执行战略工具包 有兴趣复制这种方法。该提案主要关注COVID-19疫苗接种，但 所获得的知识将与未来的疫苗公平倡议相关，如COVID-19助推器（如需要） 季节性流感疫苗。

Project Summary The COVID-19 pandemic disproportionately impacts Latinos in the US. Failing to provide equitable access to vaccines will exacerbate the profound disparities in COVID-19 and other health conditions among Latinos communities. Our team has established a community coalition and identified effective interventions to reduce disparities among low-income limited English proficiency (LEP) Latino communities using qualitative, survey, and implementation science methodologies. We will test the efficacy of a combination intervention REDES (“Networks”) - a social network and mobile health (mHealth) enhanced community health worker (CHW) intervention - to address COVID-19 vaccine hesitancy and uptake among a cohort of Latinos and their networks in Maryland. We will recruit 300 index participants who have taken the COVID-19 vaccine. Half of the index participants will be randomized to the experimental group (n=150). CHWs will train them to be peer mentors to conduct peer outreach in-person and by text messages and to promote vaccine acceptance and uptake with their networks. Index participants in the control group (n=150) will receive an equal attention intervention. In addition, we will recruit unvaccinated primary and secondary network members of indexes for study participation and COVID-19 vaccination. We will enroll an estimated total of 1,590 primary and secondary network members. All participants will be followed prospectively at 3, 6, 12, and 18 months after baseline intake. The specific aims are: 1) Evaluate the efficacy of a combination intervention REDES to promote COVID-19 vaccine uptake among Latinos; 2) Examine ongoing barriers and facilitators of vaccine uptake among Latinos and their networks to tailor our intervention and address new challenges, and 3) Evaluate the implementation determinants and outcomes of REDES to inform future broad-scale implementation. Our multi-disciplinary research team brings together Latino health, social network, mHealth interventions, vaccine hesitancy expertise; a long-term history of community engagement with partner organizations in Maryland; and existing bilingual/bicultural CHW capacity and a rich local infrastructure for COVID-19 response. If this combination intervention demonstrates the efficacy, we will develop an implementation strategy toolkit, both in English and Spanish, for community partners and health departments interested in replicating the approach. This proposal primarily focuses on COVID-19 vaccination, but knowledge gained will be relevant to future vaccine equity initiatives, such as COVID-19 boosters (if needed) and seasonal influenza vaccination.
