Creating a Tool to Help Decide When to Use Abdominal-Pelvic CT Scans for Blunt Trauma Patients

What this Trial Is About

Unrecognized abdominal and pelvic injuries from blunt trauma can lead to serious disability or death. Physicians often use computed tomography CT scans on many blunt trauma patients to avoid missing injuries, but this exposes many patients to radiation and high costs while finding injuries in only a few. Researchers are evaluating a decision tool to identify low-risk patients who may safely avoid CT imaging without missing significant injuries, aiming to reduce unnecessary scans, radiation exposure, and healthcare costs. This observational study involves adult blunt trauma patients who receive abdominal-pelvic CT scans in the emergency department. Physicians will record clinical signs and symptoms such as pain, tenderness, bruising, vital signs, and injury mechanism before imaging. The study will develop and validate decision instruments to classify patients as high or low risk for major or minor abdominal and pelvic injuries based on these clinical findings, without altering standard medical care. Participants will undergo routine clinical evaluations and CT imaging as part of their emergency care. Researchers will analyze the presence or absence of injuries using CT results and patient outcomes to assess the accuracy of the decision instruments. The main outcomes are the instruments ability to correctly identify major and minor injuries. The study aims to confirm that these tools can safely reduce CT imaging, lowering radiation exposure and costs while maintaining patient safety.
