Improving #PatientFlow during COVID-19 with FebriDx®

18 January 2021

A recent study funded by London North West University Healthcare NHS Trust has found that the simple triage algorithm including FebriDx® assay had good sensitivity and is a useful ‘rule-out’ for COVID-19. The algorithm is useful for managing medical admissions from the emergency department.


FebriDx® is revolutionising #PatientFlow during the COVID-19 pandemic by improving triaging and negating the use of isolation bays. Between 10th August 2020 and 4th November 2020 the FebriDx® triage algorithm reduced the need for 2,859 patients to be admitted to isolation rooms and was a useful ‘rule-out’ for COVID-19. Use of the FebriDx® point-of-care assay as part of a triage algorithm for medical admissions with possible COVID-19

We studied a COVID-19 triage algorithm for hospital medical admissions using clinical parameters and the FebriDx assay. The algorithm had good sensitivity and negative-predictive value compared to SARS-CoV-2 PCR. FebriDx improved triage specificity allowing fewer isolation rooms to be used.

94.9% (129/136) of patients with COVID-19 were appropriately managed in isolation rooms as a result of the triage algorithm (supplementary table 4). Of the 10 patients with PCR-confirmed COVID-19 not identified by the triage algorithm, only 7 were not managed in an isolation room. Had all patients been isolated until SARS-CoV-2 RT-PCR result was available (ie without using any triage algorithm) 2,859 more isolation rooms would have been used. The FebriDx assay allowed 826 more patients to be managed in ‘non-COVID’ areas than if all patients triaged possible COVID-19 had required isolation (9.5 isolation rooms saved per day).
