Point-of-care ultrasound during the COVID-19 pandemic: A multidisciplinary approach between intensivists and echocardiographers.

Purpose: The coronavirus disease-2019 (COVID-19) led to a large influx of critically ill patients and altered echocardiography laboratory workflow. We developed a point-of-care ultrasound (POCUS) first approach to patients requiring echocardiography and describe our workflow and findings.
Methods: We performed a single-center retrospective analysis of all POCUS studies performed on critically ill patients with COVID-19. Sonography was performed by intensivists, uploaded and archived, and rapidly reviewed by echocardiographers. We evaluated each study based on the number of views obtained. Additionally, we provide a description of the workflow during the COVID-19 surge at a tertiary care hospital in New York City.
Results: Fifty patients had POCUS studies performed by intensivists and reviewed by echocardiographers obviating the need for sonographer-performed studies. Of the 48 cardiac POCUS studies, 17% of patients had 4 of 4 standard views available while 53% had 3 of 4 standard views. The parasternal long-axis view was obtained on 81%, subxiphoid view on 79%, apical 4-chamber view on 71%, and parasternal short-axis view on 63% of patients.
Conclusions: Our POCUS workflow allowed intensivists to perform cardiac sonography for rapid bedside diagnosis of pathology with immediate interpretation performed by echocardiographers. At least 3 views were obtained in the majority of cases.
