检查便利的自采样干预和测试导航干预如何影响 COVID-19 测试
检查便利的自采样干预和测试导航干预如何影响弱势人群的 COVID-19 测试
研究概览
详细说明
在过去两年中,大流行的情况和人们在检测、感染和疫苗接种方面的经历发生了巨大变化。 疫苗已经问世,当地社区的检测机会时有起伏,人们对 COVID-19 严重性和易感性的态度也发生了转变。 驾驭测试决策环境让公众感到困惑(免费测试可用性与收费或需要保险;测试和疫苗接种地点发生变化;PCR 与抗原测试;家庭测试与临床交付;基于症状的测试、暴露驱动测试、系列测试、信任或不信任的资源等)。
这项研究称为嵌入式研究,以更广泛的人群为基础的随机对照试验 (RCT) 为基础,以评估促进自采样干预和测试导航干预对测试行为的影响。 嵌入式研究将从 RCT 中随机选择优先块组并将其分配给三个臂之一 - FSSI (n=16)、TNI (n=16) 或对照 (n=32)。 休斯顿/哈里斯县、德克萨斯州南部和德克萨斯州东北部三个地区的分配比例分别为 2:1:1。 社区卫生工作者将使用随机启动程序从每个 PBG 系统地抽样和招募 20 人。 将招募干预组的研究参与者,完成基线调查,接受简短的教育干预,并完成后续调查。 对照组的参与者将完成基线和后续调查。

参与者组/臂 |
干预/治疗 |
|---|---|
|
实验性的:促进自采样干预 (FSSI)
FSSI 部门的参与者将接受有关 COVID-19 检测的教育,并获得快速抗原检测。
参与者还将接受前后调查。
|
CHW 将同意并从随机 PBG 中招募参与者加入 FSSI。
FSSI 将由社区卫生工作者 (CHW) 在家访中提供有关 COVID-19 测试的教育干预。
此外,参与者将接受一批 4 项快速抗原检测,如果需要,可以与家庭成员或其他密切接触者共享。
社区卫生工作者将提供用于管理测试的低识字说明,包括印刷和视频。
如果社区卫生工作者检测呈阳性(例如,
隔离、通知接触者、戴口罩)。
社区卫生工作者也将通过电话向参与者提供任何后续问题。
CHW 将在干预后的两个月内通过短信和电话跟进参与者。
除了干预之外,还将要求参与者完成测试前和测试后的调查。
初步干预后两个月,将在线或通过电话进行后期调查。
|
|
实验性的:测试导航干预 (TNI)。
TNI 部门的参与者将接受 COVID-19 测试教育,并被导航到 PCR 测试站点。
参与者还将接受前后调查。
|
CHW 将同意并从随机 PBG 中招募参与者加入 TNI。
TNI 将由 CHW 主导的家访干预组成,他们将在家访中提供有关如何以及何时使用决策树模型进行 COVID 19 测试(包括抗原和 PCR)的低健康知识材料,并提供到附近 PCR 测试站点的导航、购买抗原测试的地点和支持访问联邦政府抗原测试(如果参与者尚未获得)。
除了干预之外,还将要求参与者完成测试前和测试后的调查。
初步干预后两个月,将在线或通过电话进行后期调查。

有源比较器:控制
对照组的参与者将收到 CDC 设计的 COVID-19 检测手册,以及仅前后调查。

Percentage of Community Members Reported to Have Tested Positive for COVID-19
大体时间:Baseline
|
The percentage of individuals within each participant's self-identified community network who have tested positive for COVID-19. Participants provide a list of individuals they regularly communicate with (community network). The percentage is calculated for each participant as: (Number of community members reported positive for COVID-19 ÷ Total number of community members listed) × 100. Higher percentages indicate greater COVID-19 exposure within the participant's community network. |
