Abstract
ObjectivesWe sought to determine if point‐of‐care ultrasound (POCUS) performed on patients with COVID‐19 in the emergency department (ED) can help predict disease course, severity, or identify complications.MethodsThis was a retrospective cohort study of adult ED patients who tested positive for COVID‐19 at hospital admission or within 2 weeks of presentation and received heart or lung POCUS. Clips were reviewed for presence of decreased left ventricular ejection fraction (LVEF), right ventricular dilation, presence of B‐lines, and pleural line abnormalities. Patients with worsening hypoxemic respiratory failure or shock requiring higher level of care and patients who expired were considered to have developed severe COVID‐19. Regression analysis was performed to determine if there was a correlation between ED POCUS findings and development of severe COVID‐19.ResultsA total of 155 patients met study criteria; 148 patients had documented cardiac views and 116 patients had documented lung views (113 with both). Mean age was 66.5 years old (±18.6) and 53% of subjects were female. Subjects with decreased LVEF that was not previously documented had increased odds of having severe COVID during their hospitalization compared to those with old or no dysfunction (OR 5.66, 95% CI: 1.55–19.95, P = .08). The presence of pleural line abnormalities was also predictive for development of severe COVID (OR 2.68, 95% CI: 1.04–6.92, P = .04).ConclusionPOCUS findings of previously unidentified decreased LVEF and pleural line abnormalities in patients with COVID‐19 evaluated in the ED were correlated to a more severe clinical course and worse prognosis.
