研究概览
简要总结
The purpose of the study is to compare Emergency Department patients who undergo influenza testing using an FDA-approved point-of-care device (Cobas Liat Influenza A/B assay) located in the ED, to patients whose samples are sent to the BMC central laboratory. Patients who agree to participate will have their samples randomly assigned to be tested on either at the core lab, or on the POC device. The current turnaround time for samples sent to the laboratory is approximately two hours; investigators expect that the point of care device can reduce this time. Investigators will determine if the time to disposition and the administration of antibiotics is different in the group undergoing POC influenza testing compared to those undergoing laboratory-based influenza testing

研究组 & 干预措施
Core Lab Testing Arm
For patients with clinical concern for influenza, the usual workflow in the BMC ED is that physicians order the collection of a nasopharyngeal swab (NPS) for influenza A/B testing to be performed in the core microbiology laboratory using one of two assays. The two influenza A/B-only assays available in the core lab are a) an instrumented fluorescent immunoassay rapid antigen test, the Sofia influenza A+B FIA (Quidel Corporation) and b) an automated real-time PCR test, the Xpert Flu (Cepheid, Inc.). Which test is ordered is at the discretion of the physician. Both the Sofia and Xpert assays provide a result callout to distinguish influenza type A from type B.
干预措施: Core Lab Test (Other)
ED Point of Care Testing Arm
Prior to the study the Cobas Liat Influenza A/B assay will be verified for patient care at BMC. The instrument and test kits will be available in the ED for use with study subjects randomized to this study arm. The Cobas Liat assay provides a result callout to distinguish influenza type A from type B.

结局指标
主要结局
Time to Disposition
时间窗: By the End of the ED visit (an average time of 4 hours)
The time elapsed from when a patient was placed in the ED treatment room until the disposition (either admit, observe, or discharge) was ordered in the medical record
次要结局
- Delivery of prescription or administration of antibiotics(by the end of ED visit (an average time of 4 hours))
