BackgroundWith the coronavirus disease 2019 (COVID-19) outbreak hospitals prepared for increasing numbers of patients without knowing how patient populations were evolving and what resources would be required. The present study aimed to analyze the impact of the local COVID-19 pandemic on emergency resources of all hospitals in a major urban center (Mönchengladbach) in Germany.MethodsThis observational multicenter study involved all acute care hospitals (n = 4). Systemic emergency department (ED) parameters from weeks 4-24 in 2020 were compared to the corresponding period in 2019 for each hospital and in a summative data analysis using a logistic regression model.ResultsThe first regional COVID-19 patients were detected in week 9 of 2020. The cumulative number of ED visits dropped from 34,659 in 2019 to 28,008 in 2020. Weekly ED visits per hospital decreased from week 8 onwards between 38% and 48% per week and hospital and began to rise again after week 16. The pooled data analysis of ED patients showed significant decreases in outpatient visits (20,152 vs. 16,477, p < 0.001), hospital admissions (14,507 vs. 11,531, p < 0.001), and work-related accidents (2290 vs. 1468, p < 0.001). The decrease in ED to ICU admissions showed no significance (2093 vs. 1566, p = 0.255). The decline in ED cases was equally distributed between the medical specialties.ConclusionThe regional COVID-19 outbreak led to significantly reduced ED contacts in a German major urban region after the first COVID-19 cases appeared. Both hospital admissions and the number of ED to ICU admissions decreased, whereas the ratio of emergency outpatients vs. inpatients remained stable. Therefore, it can be assumed that patients with severe medical problems did not seek emergency care. These secondary effects of the pandemic on healthcare and the socioeconomic impact should be analyzed further.© 2021. Springer Medizin Verlag GmbH, ein Teil von Springer Nature.
