Brief Summary

The objective of this study is to compare the results of a COVID-19 specific curriculum led by LACDHS Community Health Workers (CHWs) from these same communities of safety-net patients to effectively increase COVID-19 testing and vaccination for individual patients, and to facilitate needed healthcare in a timely manner for the safety net health system, and to develop a sustained public health presence in these communities to build trust and preparedness for critical COVID-19 related future needs.

Detailed Description

This study represents the third aim of a grant with three aims. The study used unsupervised machine learning and qualitative interviews to develop a CHW intervention for this aim. The aim will compare and evaluate a Community Health Worker-led curriculum aimed to identify and address barriers to COVID-19 testing and vaccination among LACDHS safety-net patients.

For the study, the investigators will recruit 66 eligible safety-net patients for a COVID-19 specific curriculum, provided by Community Health Workers at Los Angeles County Department of Health Services. The study will take place remotely over the course of 6-weeks. Utilizing a randomized control design among African American and Latinx safety net patients, will assess the effect of the CHW hypothesis-driven intervention on trust, self-efficacy, and intent to participate in COVID-19 testing and vaccination.

The remote CHW intervention that the study participants will participate in and be compensated for is a pilot program intended to provide additional CHW training. Monthly calls from LACDHS to remind them of COVID-19 vaccination are standard of care for all empaneled LACDHS patients.

GroupInterventionDescription
Intervention Arm - CHW-led curriculum (Group 2)Community Health Worker led curriculumParticipants assigned to the intervention group will complete the same activities as Group 1 and be asked to participate in the virtual intervention, consisting of six-weekly group classes via Zoom, and six-weekly personalized teleconsultations (via phone call or Zoom) at a suitable time for both participants and CHWs. Study participants will receive 6 linguistically and ethnically concordant weekly two-hour group classes and personalized teleconsultations led by CHWs. The total time commitment for Group 2 will be a maximum of 20 hours (6 two-hour group classes, + 6 one hour personal session, + 2 half hour phone calls), over the next 6 weeks.
Primary Outcome Measures
NameTimeMethod
Project Survey: Phenx toolkit - Worry about COVIDSix weeks from start of project

In a 4-point Likert scale, we will ask questions about their worry and concern about getting infected with COVID from "extremely concerned, somewhat concerned, neutral, not concerned" Measure three key measures: trust, self-efficacy, and intent to participate in COVID-19 testing and vaccination. Consolidated pre- and post- surveys (Name: Project Survey) will measure participants' intentions of getting vaccinated and tested for COVID-19.

Project Survey: Phenx toolkit - Attitudes and BehaviorSix weeks from start of project

In a 5 point Likert scale, questions will ask about attitudes, and behaviors regarding COVID, from "very likely, somewhat likely, neutral, somewhat unlikely, and very unlikely" Measure three key measures: trust, self-efficacy, and intent to participate in COVID-19 testing and vaccination. Consolidated pre- and post- surveys (Name: Project Survey) will measure participants' intentions of getting vaccinated and tested for COVID-19.

Project Survey: Phenx toolkit - Perceived Coronavirus ThreatSix weeks from start of project

In a 4-point Likert scale, we will ask questions about their perceived Coronavirus threat "extremely concerned, somewhat concerned, neutral, not concerned" Measure three key measures: trust, self-efficacy, and intent to participate in COVID-19 testing and vaccination. Consolidated pre- and post- surveys (Name: Project Survey) will measure participants' intentions of getting vaccinated and tested for COVID-19.

Secondary Outcome Measures
NameTimeMethod
Project Survey: Phenx toolkit - Intent to participate in COVID testing and vaccinationSix weeks from start of project

assessed by a single declarative item using a four-point scale (very likely, somewhat likely, somewhat not likely, very not likely). Consolidated pre- and post- surveys (Name: Project Survey) will measure participants' intentions of getting vaccinated and tested for COVID-19.

Pre and Post Program Survey: Medical Mistrust ScaleSix weeks from start of project

Trust will be measured using 8 adapted items from the Medical Mistrust scale, with a list of statements asking about general feelins about the healthcare systems, answers will be "strongly disagree, disagree, neutral, agree, strongly agree"

Sherer, et al.'s General Self-Efficacy ScaleSix weeks from start of project

It contains 17 items that are rated on a 5-point Likert-type scale ranging from agree strongly to disagree strongly and are intended to assess a "general set of expectations that the individual carries into new situations"
