Brief Summary

The study titled " The Effect of Definitive Identification of Viral Etiology in Emergency Department Patients with Acute Respiratory Infection on Antibiotic Utilization (RADIATE)" aims to investigate the effectiveness of a rapid diagnostic approach in reducing unnecessary antibiotic use in the emergency department (ED) for patients presenting with acute respiratory illness (ARI) due to a virus. Using a prospective design, eligible participants are individuals who visit the ED with complaints related to acute respiratory illness. The study will employ a single-arm consecutive enrollment approach. The intervention involves the implementation of a rapid point-of-care multiplex polymerase chain reaction (PCR) test to promptly identify the viral cause of the infection. By utilizing a rapid diagnostic tool to identify viral etiology, the study aims to provide healthcare professionals in the ED with more accurate information to guide treatment decisions. Ultimately, the goal is to decrease the unnecessary use of antibiotics for ARI's due to a virus, which has several negative outcomes including promotion of antibiotic resistance, exacerbating ED length of stay and encouraging unnecessary additional diagnostic tests.

Study Arms (1)

SPOTFIRE Arm

EXPERIMENTAL

The intervention involves the use of a rapid point-of-care multiplex PCR test to identify viral etiology in patients with acute respiratory illness. This approach aims to provide timely and accurate diagnostic information to guide treatment decisions. Specimen samples will be collected by research staff at the time of ED presentation by NPAAS. Upon collection, the sample will be promptly prepared for testing on the SPOTFIRE R Panel device. In this trial, all providers will view Spotfire results before prescribing antibiotics ; failure to so so will be a protocol violation.

Device: SPOTFIRE R Panel

Interventions

The intervention involves the use of a rapid point-of-care multiplex PCR test (Spotfire) to identify etiology of patients with ARI. Specimen samples will be collected by research staff at the time of ED presentation. Upon collection, the sample will be promptly prepared for testing on the SPOTFIRE R Panel device. The device will be in the ED to facilitate testing and accelerate delivery of diagnostic results to clinicians. The time when the provider receives the results will be recorded to evaluate the incorporation of results in clinical decision making.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Over the age of 18
