Effect of the COVID-19 pandemic on the socioeconomic composition of emergency department presentations.

Abstract

ObjectivesThis study highlights how socioeconomic trends in the emergency department (ED) for low-acuity visits change with the onset of COVID-19, identifies societal inequities exacerbated by the pandemic, and demonstrates the geographical regions where these inequities occur.MethodsWe accessed 1,285,000 ED visits from 12 different facilities across New Brunswick from January 2017 to October 2020. Using a deprivation index developed by Statistics Canada as a measure of socioeconomic status, and controlling for additional factors, we perform a logistic regression to determine the influence of the COVID-19 pandemic on low-acuity visits of individuals from the most deprived quintile (Q5). We constructed a heat map of New Brunswick to highlight regions of high deprivation.ResultsThe proportion of Q5 individuals in the ethnocultural composition domain accessing the ED for low-acuity visits increased from 22.91% to 24.72% with the onset of the pandemic. Our logistic regression showed the log odds of being considered Q5 in the ethnocultural composition domain when visiting the ED for a low-acuity reason increased by 6.3% if the visit occurred during the pandemic, and increased by 101.6% if the visit occurred in one of the 3 major regions of New Brunswick.ConclusionIndividuals visiting EDs for low-acuity reasons during the COVID-19 pandemic were more likely to be from the most diverse quintile in the ethnocultural domain, and the inequities were concentrated in the most urban regions in New Brunswick. This demonstrates that urban areas are where inequities are disproportionately faced for ethnically diverse individuals and demonstrates where policies could be focused.
