COVID-19-Related Emergency Department Visits Among Undocumented Patients in Los Angeles County

摘要

Undocumented immigrants may be vulnerable to poor COVID-19 outcomes, but also may be less likely to seek medical care. To our knowledge, there have not been any investigations of potential COVID-19 disparities by immigration status. We analyzed emergency department (ED) visit data from March 20,2020 to September 30,2020 among patients in a safety-net hospital in Los Angeles County (n=30,023). We compared the probability of COVID-19-related ED visits between undocumented immigrants and Medi-Cal patients. We also examined differences in these comparisons over time. Undocumented patients had higher odds of COVID-19-related ED visits than Medi-Cal patients (OR: 1.41, 95 CI: 1.24-1.60) for all months in the study period except September. Even in the earliest days of the pandemic, undocumented patients were more likely than Medi-Cal patients to have a COVID-19-related ED visit. Additional analyses suggest this was likely because of higher COVID-19 exposure rather than differences in ED utilization.
