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.

The Lumipulse(R) G SARS-CoV-2 Ag assay performance was evaluated on prospectively collected saliva and nasopharyngeal swabs (NPS) of recently ill in- and outpatients and according to the estimated viral load. Performances were calculated using RT-PCR positive NPS from patients with symptoms [≤] 7 days and RT-PCR negative NPS as gold standard. In addition, non-selected positive NPS were analyzed to assess the performances on various viral loads. This assay yielded a sensitivity of 93.1% on NPS and 71.4% on saliva for recently ill patients. For NPS with a viral load > 103 RNA copies/mL, sensitivity was 96.4%. A model established on our daily routine showed fluctuations of the performances depending on the epidemic trends but an overall good negative predictive value. Lumipulse(R) G SARS-CoV-2 assay yielded good performance for an automated antigen detection assay on NPS. Using it for the detection of recently ill patient or to screen high-risk patients could be an interesting alternative to the more expensive RT-PCR.
