Developing a Decision Instrument to Guide Abdominal-pelvic CT Imaging of Blunt Trauma Patients
NCT04937868 · View on ClinicalTrials.gov ↗
Study Summary
Unrecognized abdominal and pelvic injuries can result in catastrophic disability and death. Sporadic reports of "occult" injuries have generated concern, and physicians, fearing that they may miss such an injury, have adopted the practice of obtaining computed tomography on virtually all patients with significant blunt trauma. This practice exposes large numbers patients to dangerous radiation at considerable expense, while detecting injuries in a small minority of cases. Existing data suggest that a limited number of criteria can reliably identify blunt injury victims who have "no risk" of abdominal or pelvic injuries, and hence no need for computed tomography (CT), without misidentifying any injured patient. It is estimated that nationwide implementation of such criteria could result in an annual reduction in radiographic charges of $75 million, and a significant decrease in radiation exposure and radiation induced malignancies. This study seeks to determine whether "low risk" criteria can reliably identify patients who have sustained significant abdominal or pelvic injuries and safely decrease CT imaging of blunt trauma patients. This goal will be accomplished in the following manner: All blunt trauma victims undergoing computed tomography of the abdomen/pelvis in the emergency department will undergo routine clinical evaluations prior to radiographic imaging. Based on these examinations, the presence or absence of specific clinical findings (i.e. abdominal/pelvic/flank pain, abdominal/pelvic/flank tenderness, bruising abrasions, distention, hip pain, hematuria, hypotension, tachycardia, low or falling hematocrit, intoxication, altered sensorium, distracting injury, positive FAST imaging, dangerous mechanism, abnormal x-ray imaging) will be recorded for each patient, as will the presence or absence of abdominal or pelvic injuries. The clinical findings will serve as potential imaging criteria. At the completion of the derivation portion of the study the criter

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04937868
The ClinicalTrials.gov registry entry for NCT04937868 describes a study currently listed as recruiting. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 12,000 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of California, Los Angeles, which has 829 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 10 conditions, with Hip Injuries appearing as the primary indexed condition, and to 1 intervention — of which There are no interventions associated with this study is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT04937868 reports 1 study location spanning 1 distinct geographic area — top geographies include California. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above.
