Trends in Advanced Computed Tomography Use for Injured Patients in United States Emergency Departments: 2007–2010

Abstract: Objectives: Studies have documented increased advanced radiography use in U.S. emergency departments (EDs) for injured patients over the past decade. The authors explored trends in recent years (2007 through 2010) in advanced radiography use, specifically head computed tomography (CT) and nonhead CT scans.Methods: This was a retrospective analysis of ED visits conducted using data from the National Hospital Ambulatory Medical Care Survey (NHAMCS), a representative sample of the U.S. ED visits from 2007 throug… Show more

“…Th ere is an increase in the use of CT for injured patients 6 . Head CT related to trauma is also more common than CT of other body areas 6 . More than 1.7 million traumatic brain injuries (TBI) occur in the United States each year and an increase in the number and rate of head trauma has been noted in the last decade 7,8 .…”

“…1 This increase in imaging has not been accompanied by a proportional increase in the diagnosis of lifethreatening conditions, 1 but has led to longer ED stays, higher costs, and increased ionizing radiation exposure. [2][3][4][5][6] Patient preference for CT imaging varies and depends on the potential for serious injury. 7 However, these potential risks are either poorly quantified or completely unknown, limiting the extent to which outcome data can inform patient and physician shared decisionmaking about imaging.…”

“…While imaging is an integral part of high-quality emergency care, evidence demonstrates wide institution- and provider-level variation in utilization of certain studies without measurable differences in patient-centered outcomes. 22,23 The aim of CEDR is to measure imaging use to develop standard benchmark utilization rates and then compare practice among different institutions and providers, thereby allowing EDs to better identify particular studies that may be targets for decreasing utilization. At this time, safe utilization reduction practice using benchmarked imaging rates is primarily theoretical.…”
