Leveraging Social Networks to Increase COVID-19 Testing Uptake

Covid-19, Opioid Use, Substance Use

This two-year project will adapt and conduct a trial examining the ability of two recruitment strategies, chain-referral and credible messenger, to reach those who use opioids and other substances in order to increase their uptake of onsite point of care COVID-19 testing that will be delivered in two community based organizations (CBOs): Alliance for Positive Change and Argus Health Inc. In Phase 1, Adapt two implementation strategies to support COVID-19 testing uptake and sustainability, adapting elements of existing efficacious social network-based interventions via a CBPR approach. In Phase 2, we will examine and compare the efficacy of two sets of implementation strategies on (i) reach, (ii) testing uptake, (iii) service delivery (i.e. quarantine, medical care, contact tracing) and (iv) sustainability for individuals who use opioids and other drugs. In Phase 3, Elucidate and compare the system/organizational-, staff-, and individual-level factors that influence implementation (i.e. fidelity, acceptability, feasibility, sustainability) of the strategies to develop a plan for dissemination and scale-up in other CBOs who serve opioid and other substance using individuals in NYC.

Aims. Building on the expertise and community out-reach infrastructure of two community-based organizations (CBOs), Argus Community Inc. and Alliance for Positive Change, and following a CBPR approach, investigators propose to take two implementation strategies that have been proven to increase the reach, access, and uptake of HIV testing and related services, and adapt them to support the uptake and sustainability of point-of-service (POS) onsite COVID-19 testing in CBOs that target the underserved population of those who use opioids and other substances. Guided by social cognitive theory, Andersen's model of health care access and the EPIS framework, the specific aims are to: (1). Adapt two implementation strategies to support COVID-19 testing uptake and sustainability, adapting elements of existing efficacious social network-based interventions via a CBPR approach; (2). Examine and compare the efficacy of two sets of implementation strategies on (i) reach, (ii) testing uptake, (iii) service delivery and (iv) sustainability for individuals who use opioids and other drugs. Use of data drawn from Healthix, a public health information exchange, will supplement this comparison by generating a baseline of participant prior testing and health behavior to determine access to underserved populations as well as long-term influence on future testing behavior; and (3) Elucidate and compare the system/organizational-, staff-, and individual-level factors that influence implementation of the strategies to develop a plan for dissemination and scale-up in other CBOs who serve opioid and other substance using individuals in NYC. Settings. Alliance for Positive Change and Argus Health Inc have well-established partnership with members of the parent grant team following partnerships on numerous initiatives targeting HIV, HCV and STIs prevention, testing and treatment for over 20 years. Argus and Alliance have had a combined presence in the communities of Washington Heights, Harlem and the South Bronx for over 50 years, and have subsequently developed considerable trust, support and "credibility" within these communities. Design, Sample Size and Randomization. Two distinct social network recruitment strategies will be adapted and compared. Guided by the EPIS framework, SCT, and Andersen's Model, this 2-year study will comprise three phases. In Phase 1: Adaptation of outreach recruitment strategies, investigators will work with our project CAB, via a CBPR approach, to adapt chain-referral and POL strategies for uptake of COVID-19 testing, to finalize recruitment and on-site testing protocols. In Phase 2: Strategy Efficacy Trial and Implementation Evaluation, investigators will compare the two strategies in a cross-over design at two CBOs, with initial strategy assignment randomly determined and rolled out for 4 months before cross-over. Investigators will examine the impact of each strategy on (i) reach, (ii) COVID-19 testing/repeat testing, and (iii) service delivery among those who test positive for COVID-19. In Phase 3: Sustainment, CBOs will implement the strategy with more favorable outcomes in Phase 2, and investigators will examine their sustainment of the program. Implementation evaluation will identify participant-, staff-, and organizational-level factors that influence the feasibility, acceptability, and sustainability of each strategy in the CBOs. Phase 1: Adaptation of Outreach Strategies. Investigators will employ a CBPR-guided approach to adapt the social network-based outreach strategies. To do this, investigators will hold four 1-hour working groups with our CAB. All CAB members will be reimbursed for their time. These groups will address how to best employ the different strategies to reach our target population and motivate testing uptake. Protocols will be shaped by findings from working group meetings and shared back to the CAB who will provide feedback to inform changes in content and format, and help identify markers of success and potential challenges. Phase 2: Strategy Efficacy Trial and Implementation Evaluation Overview. During the first 4 months of Phase II each site will roll out a different recruitment strategy (randomly assigned 1:1) to the site Following four months of implementation, the sites will conduct a rapid PDSA through a series of four, weekly workgroups. Revisions to protocols will be made during these meetings and then the sites will "cross-over" and implement the other recruitment strategy for the next four months. Participants may be recruited twice, once in each strategy; any instances of repeat testing will be documented. Participants. In Phase 2, using two different strategies, investigators aim to enroll N=500 individuals with a history of opioid and/or substance abuse within the past 6 months. Based on the geographic catchment areas of Argus and Alliance and current demographics of their current substance using clientele, investigators anticipate participants will be 64% male, 51% African American, 39% Hispanic. Inclusion/exclusion criteria. All participants, regardless of recruitment strategy, must endorse opioid or other substance abuse in the past 6 months, and must speak English or Spanish; \>18years. Study enrollment, and consent. Once an individual is screened at the agency and determined to be eligible, Research Assistants (RAs) will obtain written informed consent for study participation and consent to access their clinical information in Healthix, a large health information exchange in NYC. Following consent, the RA will administer the baseline assessment in a private office. Participants will receive remuneration in accordance with standards in this population. These procedures will occur in the same way regardless of recruitment method into the study. Strategy Efficacy Trial and Implementation Evaluation. Chain-referral Strategy. Recruitment of seed participants. N=16 participants who meet inclusion criteria will be recruited from among clients at Argus and Alliance (n=8 at each site) to serve as seeds. Seeds will be stratified by substance use treatment status and gender. Site staff will contact selected individuals and refer those interested to the research team who will screen for eligibility. Following the completion of the screen, the participant will be offered COVID-19 testing; they will be compensated $20 for completing the interview at the end of the visit. Participants will be given the option to help recruit others to receive a COVID-19 test for a small incentive. If participants agree, they will receive a brief training on recruitment and three coupons. The participants will be instructed to give these coupons only to people they know who use substances. Chain-referral recruitment: Individuals redeeming coupons will be screened for study participation, assessed and offered COVID-19 testing. Those eligible and interested will be enrolled. Procedures for informed consent, study enrollment and peer education training will be identical to those for seeds. Participants will return after three weeks to receive a recruitment incentive of $10 for every coupon redeemed. During this second visit they will complete a brief questionnaire to quantify peer-recruitment attempts. Sample size: All participants will receive a maximum of four coupons to prevent the development of "professional recruiters." The process will continue until the sample size exceeds 125 persons (at each site) or the recruitment period is over. Based on prior work with similar populations in NYC investigators anticipate being able to recruit 125 participants for a COVID-19 test in 16 weeks. POL Strategy: Alliance and Argus have existing POL/peer outreach programs with well-established histories of community involvement. Investigators will leverage this existing infrastructure and adapt to focus on COVID-19 testing. Based on protocols developed in Phase 1, POLs will be trained to (i) initiate conversations related to stopping transmission of COVID-19; (ii) deliver effective messages endorsing benefits of COVID-19 testing, social distancing and mask wearing; (iii) identify and visit those venues known to them where those with substance use will likely congregate; (iv) set goals to engage in conversations about COVID-19 testing with the target population and (v) document/track efforts. Recruitment of participants via credible messengers: Based on these organizations' previous POL recruitment, 4 POLs are able to recruit 10 participants per week for HIV testing and related services. This will permit recruitment of 3-4 participants/week per POL (12-16 total/week), allowing completion of enrollment for outreach strategy in 4 total months. Participants recruited via POL will be consented and interviewed in the same manner as described above. Following the interview, participants will then be offered COVID-19 testing; they will be compensated $20 for completing the interview. Quality Improvement (QI)/PDSA: Following the completion of the first 4-month recruitment period, agency staff, CAB members and POLs will participate in quality improvement. Using an abbreviated PDSA protocol, stakeholders across both agencies will participate to facilitate information sharing, cross-learning, and capacity building. They will refine messaging, procedures, and educational content, and make a plan to implement change during the next recruitment period. The fourth workgroup will address issues associated with internal site logistics. Assessment and analysis. Investigators will examine the impact of the intervention on (i) reach, (ii) testing uptake and (iii) service delivery; and (iv) sustainability for individuals who use opioids and other drugs as well as potential mediating/moderating variables from the Andersen, SCT and EPIS models. Data drawn from Healthix on prior and future COVID-19 testing will augment study data to determine access to underserved populations and influence on future testing behavior. Analysis overview and main outcomes. The primary outcome of interest comparing the strategies will be testing occurrence as an indicator of testing uptake. An important secondary outcome will be reach measured through the number of coupons redeemed.
