Toussie et al determined the prognosis for a patient in the Emergency Department with COVID-19 based on the presence of opacities in the lung fields. The authors are from Mount Sinai Hospital in New York City.
Patient: COVID-19 in the ED
Chest X-ray: The left and right lung fields are each divided into 3 zones (top, middle, bottom). Each is scored for the presence or absence of opacity.
Opacity

total score =
= SUM(points for all 6 lung fields)
Interpretation:
• minimum score: 0
• maximum score: 6
• A score >= 3 is associated with intubation (odds ratio 6.2).
• Risk factors for admission were a score >= 2 (odds ratio 6.2) and obesity (odds ratio 2.4).
