COVID-19 Testing in Underserved and Vulnerable Populations

February 23, 2024 updated by: Jesse Nodora

COVID-19 Testing in Underserved and Vulnerable Populations Receiving Care in San Diego Community Health Centers

As part of National Institutes of Health Rapid Acceleration of Diagnostics-Underserved Populations (RADx-UP) program, the goal of the RADxUP study is to develop, test, and evaluate a rapid, scalable capacity building project to enhance COVID-19 testing in three regional community health centers (CHCs) in San Diego County, California. In collaboration with CHC partners, their consortium organization, Health Quality Partners (HQP), investigators are pursuing the following Specific Aims: 1) Compare the effectiveness of automated calls vs text messaging for uptake of COVID-19 testing among asymptomatic adult patients with select medical conditions and those 65 years of age and older receiving care at participating CHCs. Secondarily, investigators will invite all study participants to receive flu vaccination and will assess feasibility and acceptability of study participants to refer adult family household members who are essential workers for COVID-19 testing. 2) Gather patient, provider, CHC leadership, and community stakeholder insights to establish best practices for future scale-up of COVID-19 testing sustainability and vaccination.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Pronounced inequities and disparities in coronavirus disease (COVID-19)COVID-19 morbidity and mortality have been reported, largely due to comorbid conditions and social determinants of health. Approximately 95% of COVID-19 related deaths occur among individuals with underlying medical conditions. Of all racial/ethnic groups, Hispanic/Latino communities in San Diego County have experienced the greatest burden of COVID-19 disease and deaths. Furthermore, testing challenges to date are evident, including long turnaround of test results and longer waiting times for African American and Hispanics compared to whites. The goal of this community-engaged proposal is to develop, test, and evaluate a rapid, scalable capacity building project to enhance COVID-19 testing in three regional community health centers (CHCs) in San Diego County. In collaboration with CHC partners, their consortium organization (Health Quality Partners), and community stakeholders, investigators propose the following Specific Aims: 1) Compare the effectiveness of automated and live prompts and reminders and their combination for uptake of COVID-19 testing among adult patients with select medical conditions or those 65 years of age and older receiving care at participating CHCs. Secondarily, investigators will invite all study participants to receive flu vaccination and will assess feasibility and acceptability of study participants to refer adult family household members who are essential workers for COVID-19 testing. 2) Gather patient, provider, CHC leadership, and community stakeholder insights to establish best practices for future scale-up of COVID-19 testing sustainability and vaccination. This community-engaged project includes underserved (socioeconomically disadvantaged and large proportion of Hispanic/Latinos) as well as COVID-19 vulnerable individuals (patients with medical comorbidities and 65 years of age and older). The approach considers regional COVID-19 morbidity and mortality disparities to identify strategies to address disproportionate infection rates and follow-up. By working in partnership with health care providers, health care system leaders, and community stakeholders, the research team has the potential to build the evidence-base approaches and identify sustainable solutions to understand and address the current and future pandemics in underserved and vulnerable populations.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

21 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Eligible participants will include asymptomatic men and women receiving care at participating community health centers with at least one clinic visit in the last year, age 21 years and over, with co-morbid conditions deemed by the Centers for Disease Control and Prevention to increase risk for severe COVID-19 illness, including heart failure, coronary artery disease, cancer, chronic kidney diseases, COPD, obesity, sickle cell disease and type 2 diabetes mellitus, and those 65 years of age and older.

Exclusion Criteria:

  • Under age 21, inability to communicate in English and other study languages, inability to complete anterior nasal swab sampling for COVID-19
