Leesburg, VA, August 24, 2022—According to ARRS’ American Journal of Roentgenology (AJR), from 2011 to 2018, national utilization of chest and abdominopelvic CT for trauma-related emergency department (ED) encounters increased in commercially insured patients—especially for single-encounter thoracabdominopelvic CT examinations and for minor injuries.

Leesburg, VA, August 24, 2022—According to ARRS’ American Journal of Roentgenology (AJR), from 2011 to 2018, national utilization of chest and abdominopelvic CT for trauma-related emergency department (ED) encounters increased in commercially insured patients—especially for single-encounter thoracabdominopelvic CT examinations and for minor injuries.

“Given concerns of increased cost and incidental findings detection, further investigation is warranted to explore the potential benefit of single-encounter thoracabdominopelvic CT examinations in patients with minor injuries, as well as strategies to optimize order appropriateness,” wrote first author Ninad V. Salastekar, MBBS, MPH, from the department of radiology and imaging sciences at Emory University School of Medicine.

Using national claims information extracted from the IBM MarketScan Commercial Database, Dr. Salastekar’s team identified trauma-related ED encounters via 2011–2018 MarketScan files. ED encounters were organized using the Injury Severity Score (minor, intermediate, major) via International Classification of Diseases codes, them assessed for chest CT, abdominopelvic CT, and single-encounter thoracoabdominopelvic CT examinations.

Ultimately, in commercially insured patients, national utilization of single-encounter thoracoabdominopelvic CT per 1,000 trauma-related ED encounters increased from 3.4 in 2011 to 9.8 in 2018 (adjusted incidence rate ratios, 1.16 per year). Additionally, rates rose from 1.1 to 4.6 (1.18) for minor, 6.4 to 16.4 (1.16) for intermediate, and 99.6 to 179.9 (1.08) for major injuries.

Because their retrospective study used national claims data from commercially insured patients—excluding the majority of Medicare- or Medicaid-eligible individuals, while entirely excluding the uninsured—“the findings may not generalize to such populations,” the authors of this AJR article cautioned.


North America’s first radiological society, the American Roentgen Ray Society (ARRS) remains dedicated to the advancement of medicine through the profession of medical imaging and its allied sciences. An international forum for progress in radiology since the discovery of the x-ray, ARRS maintains its mission of improving health through a community committed to advancing knowledge and skills with the world’s longest continuously published radiology journal—American Journal of Roentgenology—the ARRS Annual Meeting, InPractice magazine, topical symposia, myriad multimedia educational materials, as well as awarding scholarships via The Roentgen Fund®.
