Clinical Trial Summary

Ultrasounds are usually done by a specially trained health professional in the hospital or emergency department (ED) setting. Using a novel single-probe device, the ultrasound can be plugged into an iOS / Android device. The purpose of this research is to assess the usefulness of lung ultrasound imaging, performed by the patient in the home setting for the management of the COVID-19 disease using this novel highly-portable ultrasound.

Description:

This will be a prospective self-controlled design. The study subjects will receive a telehealth visit from a healthcare provider (HCP) to assess for any change in their COVID-19 symptoms. The HCP will recommend the patient remain at home, or to go to an emergency department based on standard of care and clinical decision making. Subsequently, the study subjects will receive a teleguidance session with a Radiologist who is trained in lung ultrasound (LUS) in order to obtain images of their chest. The physician performing LUS remotely will report LUS findings in a standard quality assurance (QA) document, including image quality, interpretation, and recommendations. This QA report will be study data and not shared with the patient. The two providers will be blinded, except when there is a disagreement between the Telemed LUS and clinical interview.

The study staff will determine when this disagreement occurs. They will notify the study investigators and radiologist, who will then discuss and come to an agreement within 24 hours. If deemed concerning, they will then contact the HCP and unblind them as to the radiographic findings. There will be no delay in medical care advised by the subject's HCP.

Specifically, the nurse will inform the HCP by a phone call that the physician performing LUS remotely found a significant change in LUS findings. The HCP will then be given access to the LUS report (as well as images if desired), and will review the decision to seek medical care with the telemed doctor.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The efficacy of image-acquisition for patient-performed lung ultrasound as assessed by a standard Quality Assurance, including image quality, interpretation, and recommendations.	Patients will perform a lung ultrasound with teleguidance from a medical professional. This will be taken daily and monitored by an expert clinician who can guide based on the remote live transmission and probe position. The efficacy of the images obtained will be assessed using a standard Quality Assurance report using Soldati scoring which will be completed and synthesized following each appointment during the fourteen day period.	14 days
Secondary	Correlate LUS radiographic findings with patient outcomes.	The LUS radiographic findings will be assessed to determine a possible correlation between the radiographic findings and disease timeline, clinical symptoms such as median oxygen saturation percentage readings, the number of ER visits, and the number hospital admissions. The score from a radiographic assessment will be compared to the course of a subject's illness.	14 days
