Intervention to Prevent Household and Community Spread of COVID-19 Among Latinos

Tailored Behavioral Intervention to Prevent Household and Community Spread of COVID-19 Among Latinos

This study will examine the effectiveness of a 6-week behavioral intervention for patients who are recently diagnosed with COVID-19. Patients and their households will be randomized to one of two groups (Standard of Care vs. Enhanced Standard of Care). Patients in the Standard-of-Care group will receive established clinical care and follow-up. Patients in the Enhanced Standard-of-Care group will receive standard-of-care plus tailored, real-time text messaging and virtual counseling delivered by promotores/as. The investigators hypothesize that households in the Enhanced Standard-of-Care group will have fewer (any new) household COVID-19 infectivity rates compared to households in the standard-of-care group post-intervention.

Study Overview

• Status: Active, not recruiting
• Conditions: SARS-CoV-2 Infection
• Intervention / Treatment: Behavioral: COVID Prevention Program (CPP)

Detailed Description

The study team will develop and test a novel tailored behavioral intervention for patients of a Federally Qualified Health Center who are recently diagnosed with COVID-19. The study is a pragmatic, quality improvement randomized controlled trial (RCT). This research is looking to enroll 256 index patients and their households. Index patients and their households will be invited to participate in the COVID Prevention Program, which includes free COVID-19 testing for exposed household members. Index patients will be randomized to one of two groups: (a) the Standard-of-Care comparison group who will receive established clinical care and follow-up, or (b) the Enhanced Standard-of-Care group, who will receive standard-of-care plus tailored, real-time mobile/virtual counseling delivered by promotores/as. The intervention will use theory- and evidence-based strategies for behavior change and maximize the use of mobile phone applications and technologies to capture real-time behavioral, social, and contextual data (via Ecological Momentary Assessment). The intervention will utilize motivational interviewing techniques to tailor strategies to index patients' home environment/context and social/emotional needs. The intervention will target immediate risk of household spread, followed by risk of community spread. The primary outcome assessed will be a new positive antibody test within a household (post-baseline), as assessed by a blood draw collected by a certified phlebotomist. Secondary research outcomes will be assessed via self-report surveys. Surveys will include socioeconomic status indicators and demographics, as well as measures of mental health (e.g., depression), physical health (chronic conditions), health behaviors (social distancing, hand washing & wearing face covering), as well as comorbidities and risk factors for severe COVID-19 outcomes. Primary and secondary outcomes will be measured at 5 timepoints: baseline, 6-weeks, 6-months, 12-months, and 24-months.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Standard-of-Care; Patients who test positive will receive a call from the provider who conducted the test to notify them of the test result and provide standard-of-care counseling (e.g., health education, link them to resources). Index patients are entered into a COVID-19 patient registry in the Federally Qualified Health Center's electronic health record system (which also is linked to the clinic's COVID-19 dashboard) and monitored closely, with telemedicine follow-ups provided by skilled clinical staff every two-to-three days, and in-person follow-ups provided as needed.	Behavioral: COVID Prevention Program (CPP); This project is a promotor/a-led COVID-19 Prevention Program (CPP) for Latino patients of a Federally Qualified Health Center (FQHC) who are recently diagnosed with SARS-CoV-2. The program will implement immediate risk reduction strategies to prevent household spread of COVID-19, followed by risk reduction strategies to prevent community spread. Patients and household members who agree to participate will be patients of the FQHC (the covered entity) and will have completed a broad consent that authorizes program activities (e.g., COVID-19 testing, individualized counseling). Patients are free to refuse to participate in the CPP without impact on other services they may receive at the clinic. Research activities will be managed by study's measurement team, which involves surveys conducted on index patients at baseline, 1-, 6-, 12-, and 24-months. Written informed consent will be obtained for all research activities occurring outside of clinical care.
Experimental: Enhanced Standard-of-Care; In addition to the aforementioned standard-of-care actions, index patients in the enhanced standard-of-care group will receive tailored phone/mobile counseling (motivational interviewing) focused on implementing strategies to prevent immediate household spread of COVID-19, followed by weekly text messaging for a total of 6 weeks.
