Clinical Characteristics and Management of Patients with a Suspected COVID-19 Infection in Emergency Departments: A European Retrospective Multicenter Study.

Background: Our aim is to describe and compare the profile and outcome of patients attending the ED with a confirmed COVID-19 infection with patients with a suspected COVID-19 infection. Methods: We conducted a multicentric retrospective study including adults who were seen in 21 European emergency departments (ED) with suspected COVID-19 between 9 March and 8 April 2020. Patients with either a clinical suspicion of COVID-19 or confirmed COVID-19, detected using either a RT-PCR or a chest CT scan, formed the C+ group. Patients with non-confirmed COVID-19 (C− group) were defined as patients with a clinical presentation in the ED suggestive of COVID-19, but if tests were performed, they showed a negative RT-PCR and/or a negative chest CT scan. Results: A total of 7432 patients were included in the analysis: 1764 (23.7%) in the C+ group and 5668 (76.3%) in the C− group. The population was older (63.8 y.o. ±17.5 vs. 51.8 y.o. +/− 21.1, p < 0.01), with more males (54.6% vs. 46.1%, p < 0.01) in the C+ group. Patients in the C+ group had more chronic diseases. Half of the patients (n = 998, 56.6%) in the C+ group needed oxygen, compared to only 15% in the C− group (n = 877). Two-thirds of patients from the C+ group were hospitalized in ward (n = 1128, 63.9%), whereas two-thirds of patients in the C− group were discharged after their ED visit (n = 3883, 68.5%). Conclusion: Our study was the first in Europe to examine the emergency department's perspective on the management of patients with a suspected COVID-19 infection. We showed an overall more critical clinical situation group of patients with a confirmed COVID-19 infection.

Observational study on chest pain during the Covid-19 pandemic: changes and characteristics of visits to a Norwegian emergency department during the lockdown.

BACKGROUND: Following the spread of the Covid-19 pandemic in 2020, reports emerged on decreasing emergency department (ED) visits in many countries. Patients experiencing chest pain was no exception. The aim of the current study was to describe how the Covid-19 pandemic and the subsequential lockdown impacted the chest pain population in a Norwegian ED. METHODS: All patients presenting to the ED with chest pain during the study period were included. Data were collected retrospectively from the time period January 6th to August 30th, 2020, and compared to the corresponding period in 2019, assessing variations in the number of ED visits, severity, gender, and age. RESULTS: Fewer patients with chest pain were seen in the ED following the national lockdown in Norway, compared to the corresponding 2019 period (week 13: 38% fewer; weeks 11-27: 16% fewer). By week 28, the rate normalized compared to 2019 levels. There was a relative increase in lower acuity patients among these patients, while fewer moderate acuity patients were seen. During the initial period following lockdown, the median age was lower compared to the corresponding 2019 period (58 years (IQR 25) vs 62 years (IQR 24), respectively). Admissions due to acute coronary syndromes (ACS) remained proportionally stable. CONCLUSIONS: Succeeding the Covid-19 outbreak and the subsequent national lockdown in Norway, fewer chest pain patients presented to the ED. Paradoxically, the patients seemed to be less severely ill and were on average younger compared to 2019 data. However, the proportion of patients admitted with ACS was stable during this period. This could imply that some patients may have failed to seek medical advice despite experiencing a myocardial infarction.

Patient visits to an emergency department in anticipation of the COVID-19 pandemic. / Pasienttilstrømming i et akuttmottak i påvente av covid-19-pandemien.

BACKGROUND: The Emergency Department in Trondheim has prepared for a large influx of patients infected with the SARS-CoV-2 virus. We conducted a study comparing patients in the Emergency Department in the first weeks of the pandemic in Norway (weeks 11 and 12) with the average number of patient visits. MATERIAL AND METHOD: Data from patients at the Emergency Department of St Olav's Hospital in the period 6 January 2020-22 March 2020 were retrieved from the Emergency Department's database. Logistical patient data concerning patient numbers, chief complaints, length of stay in the Emergency Department, acuity level, isolation status, and treatment level were analysed. RESULTS: In week 12, 331 patients were referred to the Emergency Department, a reduction of 39 % compared with the average of 541 patients in weeks 2-10. There was a general reduction in all patient groups, but particularly those discharged from the Emergency Department. In week 12 there were 56 more patients isolated with suspected/potentially infectious disease (187 %) compared with the average for weeks 2-10, and these patients spent almost two hours longer in the Emergency Department than other patients. INTERPRETATION: There was a reduction in patient visits to the Emergency Department in the first weeks of the pandemic. The percentage of patients isolated for infection control increased, and the time spent in the Emergency Department for these patients was greater than for other patients. The reduction in the inflow of patients is expected to be temporary, and the Emergency Department at St Olav's Hospital expects a large influx of patients with suspected COVID-19 disease.
