Measure
Rapid Respiratory Pathogen Test Arm
ED patients in this arm will receive a rapid respiratory pathogen nucleic acid amplification test plus usual care. Rapid respiratory pathogen nucleic acid amplification test: Patients randomized to the rapid respiratory pathogen nucleic acid amplification test (Film Array Respiratory Panel, BioFire Diagnostics), will receive usual physician-directed care plus results from a rapid diagnostic test for 20 common respiratory pathogens. Patients will have a nasopharyngeal swab sample collected and tested during the ED episode of care with results reported in the electronic medical record (EMR) within two hours of sample collection. ED physicians will receive education regarding the rapid respiratory pathogen test prior to commencing the study. During the study, ED physicians will be free to review and interpret the respiratory pathogen test results and make treatment decisions based on their individual clinical judgment without involvement of study personnel.
Usual Care Control Arm
ED patients in this arm will receive clinician-directed standard of care, which may include but is not limited to no testing, point-of-care influenza testing, or delayed testing for respiratory pathogens at off-site laboratory.
