ABSTRACT
The coronavirus disease-2019 (COVID-19) pandemic has imposed unforeseen and unprecedented constraints on emergency departments (EDs). In this study, we detail the organizational and managerial tools recently implemented among 5 academic EDs in a French region particularly affected by COVID-19 and analyze how EDs responded to the COVID-19-related disease burden during different phases of the epidemic. Initially, they focused on the early detection of suspected cases by identifying 3 predominant COVID-19 syndromes. During this diagnostic process, patients were placed in respiratory isolation (facial mask before triage) and droplet isolation (ED rooms). A 3-level strategy for triage, clinical pathways in the EDs, and the organization of hospital spaces was based on the real-time polymerase chain reaction (RT-PCR) COVID-19 positivity rate, with ED strategies adapted to the exigencies of each level. This crisis demonstrated hospitals' adaptability and capacity to mobilize in the face of new risks, with hospitals and EDs coordinating their management to reallocate resources, optimize interoperability, and rethink patient pathways. This report on their processes may assist hospitals and EDs in areas currently spared by the new variants.
ABSTRACT
ED-visits and through-ED admissions to medical/surgical wards (MSW) and intensive care unit (ICU) during influenza, COVID-19 and lockdown periods were evaluated in a four-hospital prospective observational study from November 2018 to March 2020. ED visit characteristics and main diagnostic categories were assessed. Analysis of 368,262 ED-visits highlighted a significantly increasing trend in ED-visits during influenza followed by a significantly decreasing trend after lockdown. For MSW-admissions, a pattern of growth during influenza was followed by a fall that began during COVID-19 pandemic and intensified during the lockdown. For ICU-admissions, a significant rise during the COVID-19 pandemic was followed by diminution during the lockdown period. During lockdown, significantly diminishing trends were shown for all diagnostic categories (between -40.8% and -73.6%), except influenza-like illness/COVID cases (+31.6%), Pulmonary embolism/deep vein thrombosis (+33.5%) and frequent users (+188.0%). The present study confirms an increase in demand during the influenza epidemic and during the initial phase of the COVID-19 epidemic, but a drop in activity during the lockdown, mainly related to non-COVID conditions. Syndromic surveillance of ILI cases in ED is a tool for monitoring influenza and COVID-19, and it can predict ED activity and the need for MSW and ICU beds.
