Background Emergency department visits associated with Coronavirus Disease 2019 (COVID-19) continue to indicate racial and ethnic inequities. We describe the sociodemographic characteristics of individuals receiving COVID-19 vaccination in the emergency department and compare with an outpatient clinic population and emergency department (ED) patients who were eligible but not vaccinated. Methods We conducted a retrospective analysis of electronic health record data at an urban academic ED from May to July 2021. The primary aim was to characterize the ED-vaccinated population, compared with ED patients who were eligible but unvaccinated and the physically adjacent outpatient vaccination clinic population. Results A total of 627 COVID-19 vaccinations were administered in the ED. Overall, 49% of ED patients during that time had already received at least one vaccine dose prior to ED arrival. Hispanic, non-Hispanic Black patients, and patients on non-commercial insurance had higher odds of being vaccinated in the ED as compared with outpatient clinic setting. Among eligible ED patients, men and patients who were uninsured/self-pay were more likely to accept ED vaccination. Conclusions This ED COVID-19 vaccination campaign demonstrated a higher likelihood to vaccinate individuals from racial/ethnic minority groups, those with high social vulnerability, and non-commercial insurance, when compared with a co-located outpatient vaccination clinic.

There is minimal literature to support the appropriate dosing for the initiation of IV regular insulin therapy in DKA patients. A 0.1 unit/kg bolus followed by 0.1 units/kg/hour or 0.14 units/kg/hour is commonly utilized and recommended in guidelines.We sought to assess clinical and safety outcomes associated with various insulin infusion starting doses in patients diagnosed with DKA in the emergency department in an effort to help guide prescribing.A retrospective cohort study was conducted within an academic emergency department and included patients who received continuous infusion regular insulin with an ICD-10 code for DKA between January 2016 and January 2019. A predictive regression model was applied to test if predefined lab values influenced the starting insulin infusion rates. Clinical and safety outcomes were evaluated by starting insulin infusion rate. Data was analyzed based on starting insulin infusion rates.347 patients met inclusion criteria with 92 (26.5%) patients receiving0.07 units/kg/hr, 123 (35.4%) patients receiving 0.07 to 0.099 units/kg/hr, 123 (35.4%) patients receiving 0.10 to 0.139 units/kg/hr, and 9 (2.6%) patients receiving ≥0.14 units/kg/hr. After adjusting for baseline labs, glucose was the only significant predictor of the initial infusion rate (p0.001). For every 100 mg/dL increase in the baseline glucose value, the initial infusion rate increased by 0.005 units/kg/hr. There was no difference between insulin starting infusion rates and length of stay, rates of hypoglycemia, hypokalemia, or dysrhythmias.Glucose levels significantly influenced the insulin starting infusion rate, with no identified differences in adverse effects or clinical outcomes.
