The Use of Ultrasound in Establishing COVID-19 Infection as Part of a Trauma Evaluation
The Use of Ultrasound in Establishing COVID-19 Infection as Part of a Trauma Evaluation
The current COVID-19 pandemic is providing healthcare organizations with considerable challenges and opportunities for rapid cycle improvement efforts, in diagnostic and patient management arenas. Healthcare providers are tasked with limiting the use of personal protective equipment while minimizing unnecessary exposures to the virus. Results from real-time PCR tests to detect active COVID-19 infections may not be available in a timely fashion during emergent trauma assessments. Since the start of the COVID-19 pandemic, a rapidly expanding body of literature has identified a pattern of imaged lung abnormalities with CT and ultrasound (US) characteristic of an active viral infection. US evaluation provides a reliable, portable, and reproducible way of evaluating acute patients in a real time setting. During initial trauma evaluations, patients may also receive adjunct imaging modalities like the Focused Assessment with Sonography in Trauma (FAST) exam designed to discover life threatening findings that may require urgent interventions. We therefore propose a study expanding on the current FAST adjunct evaluation in the trauma bay that may include lung parenchyma imaging at the initial assessment to help stratify patients into low or high-risk groups for active COVID-19 infections. We believe the use of point of care US in the initial assessment of the trauma patient may help identify potentially infected individuals and aid ED providers to best directing subsequent laboratory and imaging evaluations for these patients, while further directing the necessary protective measures for additional team members involved in the care of the injured patient.
The current coronavirus disease 2019 (COVID-19) pandemic has created a unique situation for initial healthcare providers who strive to provide optimal medical care while minimizing personal exposure in acute scenarios. Although the morbidity and mortality for this disease is low for young healthy individuals, it presents a potentially serious threat to older healthcare providers or those providers with chronic medical conditions. Once a patient arrives emergently to the emergency department (ED) setting, ED providers must act promptly to evaluate these individuals for COVID-19 infection risk factors such as exposure, symptoms, and chronic medical conditions. However, some medical and surgical patients presenting emergently for evaluation are unable to provide a reliable medical history due to age, drugs, the absence of a next of kin, or altered mental status. Acutely traumatized patients often undergo computed tomography of the chest during their comprehensive evaluation. Adding a rapid bedside ultrasound of the chest as a research procedure could allow validation of ultrasound to help stratify medical and surgical patients into high and low risk of COVID-19 categories, with no radiation exposure, and far faster than current COVID-19 diagnostic PCR testing.
Aims: The project proposes to collect data that will inform a novel strategy to mitigate risk to providers by providing early, objective, and rapidly collected end organ data which will permit the stratification of pediatric trauma patients into low or high risk COVID-19 categories. The project will collect and evaluate lung ultrasound (US) findings in an expanded Focused Assessment with Sonography in Trauma (FAST) evaluation of the chest of pediatric trauma patients. The term "FAST+" is used to denote the use of FAST expanded to image the select lung fields in traumatized patients. The researchers hypothesize that FAST+ will result in identification of pulmonary findings indicative of COVID-19 infections and will significantly correlate with the gold standard derived from computed tomography (CT) performed in parallel in these traumatically injured patients.
