Abstract

Objective To compare a point of care (POC) nucleic acid amplification based platform for rapid diagnosis of COVID-19 against the standard laboratory RT-PCR test and perform an implementation study. Design: prospective clinical trial (COVIDx) and observational study Setting: a large UK teaching hospital Participants: patients presenting to hospital with possible COVID-19 disease and tested on a combined nasal/throat swab using the SAMBA II SARS-CoV-2 rapid POC test and in parallel a combined nasal/throat swab for standard lab RT-PCR testing. Implementation phase participants underwent SARS-CoV-2 POC testing for a range of indications over a ten day period pre and post SAMBA II platform implementation. Main outcome measures: concordance and sensitivity and specificity of POC using the lab test as the reference standard, test turnaround time in trial and implementation periods; time to definitive patient triage from ED, time spent on COVID-19 holding wards, bay closures avoided, proportions of patients in isolation rooms following test, proportions of patients able to be moved to COVID negative areas following test. Results 149 participants were included in the COVIDx trial. 32 (21.5%) tested positive and 117 (78.5%) tested negati...Continue Reading
