Abstract | Objectives: This study aimed to evaluate the clinical performance of a combined SARS-CoV-2/influenza rapid antigen test (SIRAT) and to evaluate a SIRAT-based hospital isolation policy awaiting RT-PCR results for patients presenting at the emergency department (ED). Methods: We performed a prospective observational study including all adult patients presenting with influenza-like symptoms at the ED of two hospitals from 31 October 2022 to 31 March 2023. A SIRAT and SARS-CoV-2 and influenza RT-PCR were performed on upper respiratory samples. SIRAT results were compared with RT-PCR. Droplet and contact isolation measures (DCIM) were imposed based on SIRAT results awaiting RT-PCR. We monitored symptomatic nosocomial SARS-CoV-2 and influenza infections potentially caused by delayed isolation of patients with false negative SIRAT and the hours of unnecessary DCIM saved. Results: We included 1740 patients of whom 1296 were hospitalized. SARS-CoV-2 and influenza A/B prevalence were 12.7% (221/1740) and 9.9% (171/1740). Sensitivity and specificity of the SIRAT were 67.7% (95% CI 61.1-73.9%) (149/220) and 99.4% (95% CI 99.0-99.8%) (1510/1518) for SARS-CoV-2 and 52.7% (95% CI 44.9-60.4%) (89/169) and 99.1% (95% CI 98.5-99.5%) (1530/1544) for influenza A/B. We found a 0% nosocomial transmission risk for SARS-CoV-2 (95% CI 0-8.8%) and influenza (95% CI 0-10%). In all, 8712 hours in total or a median up to 6 hours 59 minutes (IQR (interquartile range) 11h03) per patient of unnecessary DCIM were saved. Discussion: A SIRAT-guided hospital isolation policy awaiting RT-PCR results for patients who present at the ED can save unnecessary isolation hours without having to lead to significant symptomatic nosocomial transmission of SARS-CoV-2 or influenza viruses. |
