Rapid Diagnosis of Viral Acute Respiratory Infection to Decrease Unnecessary Antibiotic Utilization in the Emergency Department (RADIATE)

United States200 participantsStarted 2024-03-12

Plain-language 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.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
