1210-P: Associations between HbA1c, Area Level Social Vulnerability, and Poor COVID-Outcomes

Background: HbA1c has been associated with COVID-poor outcomes in diabetic and non-diabetic populations, while patients living in census tracts with high levels of social vulnerability [measured using the CDC’s Social Vulnerability Index (SVI) ] have experienced poorer outcomes. Objective: To examine associations between HbA1c, area level social vulnerability and poor COVID outcomes in patients who tested positive for COVID and were captured in the electronic medical record (EMR) at a large academic institution in the Southeastern United States. Methods: HbA1c and SVI, collected up to 3 years prior to a positive COVID test, were extracted from the EMR. HbA1c and SVI were compared by poor outcome status [hospitalization, intensive care unit (ICU) admission, and mortality]. Bayesian logistic regression was used to examine associations between HbA1c [≤5.7%; 5.7%-
