DISABILITY AND COVID-19 TESTING: A CROSS-SECTIONAL RADx-UP STUDY

ABSTRACT

Background: Nearly 26% of adults in the U.S. live with disability and are more likely to experience chronic health conditions, barriers to healthcare, and severe COVID-19 illness. Therefore, COVID-19 testing of adults living with disability is important to consider. The purpose of this study was to explore relationships between disability and COVID-19 testing, infection, and related challenges. Method(s) A Rapid Acceleration of Diagnostics-Underserved Population (RADx-UP) project in Miami, FL determined disability with a modified version of the Washington Group General Disability Measure. HIV serostatus and COVID-19 vaccination were confirmed with medical records. COVID-19 testing and infection history were self-reported. Statistical analyses included chi-squared tests and multiple binary logistic regression;variance inflation factors were calculated to ensure absence of collinearity. Result(s) A total of 1,689 RADx-UP participants with an average age of 55+/-12.3, 51% male, 49% Black non-Hispanic, 23% living with HIV (86% virally suppressed), and 76% received at least one dose of a COVID-19 vaccine. Nearly 40% were disabled, 37% reported employment disability, and 21% were functionally disabled (disability that interferes with performance of daily activities). Despite recruitment from the same sources, PLWH, compared to those without HIV, were more likely to be disabled (52% vs 36%;p< 0.0001), report employment disability (63% vs 30%;p< 0.0001), and report functional disability (29% vs 18%;p< 0.0001). Those with employment disability were less likely to have ever been tested for COVID-19 compared to those without (81% vs 85%;p=0.026). Employment disability was also associated with lower odds of having ever tested positive for COVID-19 after adjustment for demographics, health insurance, HIV, COVID-19 vaccination, smoking, and lung disease (aOR, 0.62;95% CI, 0.43-0.90;p=0.013). Disability was associated with greater odds of transportation challenges (aOR, 2.33;95% CI, 1.76-3.08;p< 0.0001), illicit drug use (aOR, 1.92;95% CI, 1.49-2.47;p< 0.0001), and smoking (aOR, 1.74;95% CI, 1.39-2.17;p< 0.0001). Compared to those without, those with transportation challenges (14% vs 40%;p< 0.0001) and illicit drug use (18% vs 30%;p=0.001) were more likely to postpone medical care. Conclusion(s) Lower COVID-19 testing rates may contribute to underestimated COVID-19 positivity rates in adults living with disability. Challenges with transportation and substance abuse contribute to less engagement in care.
