Pattern of Visits in a Metropolitan Emergency Department in Lombardia (Italy): January 2019-December 2020.

ABSTRACT

During the Coronavirus disease 2019 (COVID-19), a general decrease in the presentations to emergency departments (ED) was reported. However, we suspect that there was a lower number but an unchanged pattern of ED visits for urgent conditions in 2020 compared to 2019. This retrospective study assessed the change in the number of presentations in the ED of a tertiary level university hospital in Milano (Lombardia, Italy). Compared to 2019, a significant drop in ED presentations occurred (-46.4%), and we recorded a -15.7% difference in the proportion of patients admitted with white codes. The pattern of hourly presentations to the ED was unchanged, with overcrowding during the working daytime. COVID-19 changed ED flows, likely causing an overall reduction in the number of deferrable conditions. However, the pattern associated with urgent conditions did not change abruptly in 2020.
