Wells Score to Predict Pulmonary Embolism in Patients with Coronavirus Disease 2019

Of 459 patients with COVID-19, 64 had a CTPA and 12 (19%) had evidence of pulmonary embolism. Previous or current evidence of deep vein thrombosis, a Wells score above four points, and serum D-dimer levels five times above age-adjusted upper normal values were associated with pulmonary embolism. However, only 33% of patients with PE had a Wells score of four points or higher. The AUC/ROC showed non-discriminating values (0.54) CONCLUSION: While a Wells score of four or more points predicted pulmonary embolism in our cohort, the outcome can be present even with lower scores.
