What Is the Diagnostic Accuracy of Point-of-Care Ultrasonography in Patients With Suspected Blunt Thoracoabdominal Trauma?

Authors included 34 studies (8,635 patients) from an initial 2,872 publications. The setting for half of the studies was the United States. Twenty-two studies were prospective, 10 were retrospective, 1 was cross-sectional, and 1 was a cross-sectional validation study. Ten studies included only pediatric and adolescent patients, 2 included only adults, and 22 enrolled patients of all ages. Four studies evaluated thoracic trauma only. CT was the reference standard in 25 studies, and 7 studies used a combination of CT and laparotomy.
