The impact of COVID-19 pandemic on emergency department visits and associated mortality during 14 months of the pandemic in Israel

Abstract

Background: A substantial drop in emergency department (ED) visit volume was previously demonstrated at the onset of the COVID-19 pandemic. Objective: To examine changes in the number of non-COVID adult ED visits and their associated 30-day mortality during 14 months of the pandemic in Israel. Methods: This is a retrospective cohort study including 1,285,270 adult ED visits between 1st March, 2018 and 30th April, 2021 to the internal and surgical EDS in eight general hospitals of the largest healthcare organization in Israel. The 14 months of the pandemic period (March 2020–April 2021) were divided into seven periods according to dates of the three lockdowns. Exposure to each of these periods was compared to the parallel period during the two previous years. March 2020–April 2021 was compared to the parallel periods in 2018 and 2019. Results: During the pandemic period, the largest decline in ED visits (44.6% and 50.9% for internal and surgical EDs, respectively) and the highest excess 30-day mortality following an ED visit (internal EDs Adjusted OR (ORadj), 1.49; 95% CI, 1.34–1.66 and surgical EDs: ORadj 1.50; CI, 1.16–1.94) were 95%, observed during the first lockdown. Both gradually levelled-off subsequently until near-normalization was reached in March–April 2021 for both parameters. Conclusions: A substantial decline in non-COVID ED visits and excess mortality at the beginning of the pandemic, are probably the results of social distancing restrictions alongside patients’ fear of exposure to COVID-19, which gradually moderated thereafter, until near normalization was reached after 14 months. Gradual return to pre-pandemic ED utilization patterns were noticed as the population and the healthcare system acclimatize to life alongside COVID.
