Rapid Diagnosis of Viral Acute Respiratory Infection to Decrease Unnecessary Antibiotic Utilization in the Emergency Department (RADIATE) : [BFD-RST-23-004] Rapid Diagnosis of Viral Acute Respiratory Infection to Decrease Unnecessary Antibiotic Utilization in the Emergency Department (RADIATE)

This prospective single-center, single-arm clinical trial will be conducted to study the initiation of a new diagnostic pathway for acute respiratory illness. After confirming eligibility following ED triage, patients will be enrolled to undergo the Spotfire syndromic assessment (Biomerieux, Inc.). Samples for the test will be collected via a nasopharyngeal swab administered by triage nurse or ED technician in triage. Results from test will be available in approximately 15 minutes. Patients with signs and symptoms of sore throat determined by throat pain or exudates on tonsils will also be tested for Group A streptococcus at enrollment.Prior to enrollment, the research team asked the initial clinician to delay ordering additional tests until the test was resulted.Patients who present to the ED with complaints of ARI will be considered eligible for the study. 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.For providers who do prescribe antibiotics, the investigators will ask for rationale for antibiotic prescription. Possible causes include: (1) concern for non-respiratory co-infection; (2) concern for respiratory co-infection. (3) patient request; (4) mitigation of legal risk. (5) significant co-morbidities. (6) personal preference / long-standing practice. (7) considered local standard of care. (8) other. In addition to questions above, investigators will specifically ask if physician was more likely to give antibiotics because the viral test was negative.Patients will also be queried about why they came to the ED including if they had a specific intention to receive antibiotics, additional testing or other reasons.Both patients and providers will be asked about their confidence in diagnosis, importance of getting results same day.The investigators will record the time of triage, time of nasopharyngeal swab, time of test results and time communicated with clinician and time that any additional tests are ordered. The results of the test include the presence of any pathogens.After discharge, patient will receive a chart review, including ICD-10 code, disposition, summary of test results, Strep test ordered and resulted, antibiotics given in ED (and time), ED length of stay, ED discharge, additional diagnostic tests (i.e., chest X-ray, other lab tests.)The trial was designed to measure the antibiotic prescribing rate for subjects with a definitive viral etiology, a definitive bacterial etiology and no etiology identified. The study team planned an analysis to assess the antibiotic prescribing rate of those with a definitive viral infection versus those with no etiology identified or bacterial origin.For all consented and tested patients, the investigators will record baseline patient demographics and characteristics. Group data will be compared for equality and inequality of variances, and for non-normality. Continuous variables between groups will be compared by their means using appropriate t-tests after testing for equality of variances. Discrete or categorical variables will be compared between groups by their proportions using chi-square tests. Non-normal data will be tested using non-parametric tests where appropriate. The testing of the difference between groups of some outcome variables will be done with adjustment for their baseline measures. Either an Analysis of Covariance for continuous data or a logistic regression for discrete data will be used as appropriate for these procedures. A minimum significance interval of 0.05 will be used for all comparison tests..
