1108. Feasibility and Impact of a Monoclonal Antibody Infusion Program in Reaching Vulnerable Underserved Communities

Abstract

Abstract Background Monoclonal antibodies (mAbs) against SARS-CoV-2 are potent therapeutics that prevent progression of disease in high-risk patients. Deploying mAb infusion programs and reaching communities in need remains challenging. We established a mAb infusion program centered in the emergency department (ED) fast-track. We seek to assess the feasibility and impact of our mAb infusion program in reaching vulnerable underserved communities. Methods The ED fast-track was repurposed for mAb infusions. Indications and protocols were created by the infectious disease (ID) physician and antimicrobial stewardship program (ASP). Test to treat was deployed in the ED and a referral program connected patients from telehealth and providers in the community to the infusion program (Figure 1). Data on mAb use from November 2020 to February 2022 was reviewed. To assess the reach of the program in vulnerable communities, the COVID-19 Community Vulnerability Index (CCVI) map by zip code was used. The CCVI identifies communities at risk by using variables such as sociodemographic variables, occupational factors, cumulative COVID-19 burden, vaccine uptake and other factors. Figure 1.Monoclonal antibody infusion test-to-treat and referral process in the ED fast track Results mAbs were successfully deployed and sustained throughout the pandemic, increasing its use in each COVID-19 surge by >103% (Figure 2). A total of 267 patients were treated, with an average age of 52 years, of which 55% (147) were female. Ethnicity was 46% Hispanic and Race was 54% White, 28% Black, 1.4% Asian, 1.8% Multiracial and 14% Other. Zip codes by CCVI were 64% high, 18% medium, and 3% low CCVI index. 15% were outside of city limits without CCVI index (Figure 3). Figure 2.COVID-19 Community Vulnerability Index (CCVI) of patients who received monoclonal antibodies at our program Figure 3 Monoclonal antibody infusions by COVID-19 Community Vulnerability Index (CCVI) and Zip codes Conclusion A mAb infusion program with test to treat and referrals from the community was successfully deployed in an ED fast track. The ED space and staff can be leveraged for mAbs during surges amid clinic staffing challenges. The program adopted novel mAbs as new COVID-19 variants emerged. Uptake increased with each wave, likely reflecting awareness of mAbs and the infusion program by patients and providers in the community. The majority of patients served (82%) were of high and medium CCVI. Thus, this mAb infusion program led by ID and ASP successfully reached predominantly underserved vulnerable populations.
