Emergency Department and COVID-19 Pandemic Stress Test: A Comparison between Two European Settings.

OBJECTIVE

The aim of the study was to analyze the changes in the emergency department (ED) activity of two hospitals during the 2020 lockdown and corresponding timeframes in 2019 and 2021 to assess whether a more structured primary healthcare service could have influenced the COVID-19 pressure on the ED.

SUBJECT AND METHODS

This is a multicenter, retrospective study on adult subjects registered to the selected ED during the timeframes considered. Patients <16 years old and women with obstetric or gynecological complaints were excluded. Study period was from 9 March to 3 May for the Italian ED (55 days) and March 14 to May 10 for the Spanish ED (57 days) in 2019, 2020, and 2021. Primary outcome includes difference in the number of ED admissions. Secondary outcomes consist of differences in hospital admission rates, priority code at triage, and disease group.

RESULTS

Overall, a greater number of patients flowed through the Spanish ED (14,034 vs. 8,569 in 2019, 7,208 vs. 3,101 in 2020, and 13,214 vs. 5,555 in 2021), with smaller proportional declines and lower admission rates (13% vs. 16.9% in 2019, 19.6% vs. 34.3% in 2020, and 14.3% vs. 26.3% in 2021) observed. Most referrals were for nonemergency conditions, followed by trauma and intoxications.

CONCLUSIONS

In comparison with the Italian setting, the Spanish ED showed increased activity alongside lower hospitalization rates. Further investigation is required to evaluate the potential role of more structured primary healthcare assistance in enhancing the discharge rate to homecare or primary healthcare facilities during the specified timeframes.
