| Popis: | Background Whole-body computed tomography (WBCT) has been a mainstay and an integral part of the evaluation of polytrauma patients in trauma centers and emergency departments (ED) for a comprehensive evaluation of the extent of injuries. However, routine use of WBCT remains controversial since it exposes patients to radiation and exponentially increases financial expense. The primary objective was to determine the rate of negative WBCT in polytrauma patients. Patients and Methods A retrospective cohort study was conducted at an academic hospital in the Kingdom of Saudi Arabia, which is a dedicated trauma center with a mean of 237,392 ED visits and 10,714 trauma per year. The study included all adult (≥18 years) polytrauma patients who presented to our ED, requiring trauma team activation, and underwent WBCT as part of their evaluation from January 2016 to May 2017. We excluded pediatric patients, patients transferred from another facility, and pregnant patients. The primary endpoint was to measure the rate of negative WBCT in polytraumatized patients. Results A total of 186 patients were included with a mean age of 28.8 ± 12.9 years. The rate of negative WBCT scans was 20.4%. The positive scans were subclassified based on the number of anatomical body regions that were affected radiologically. One body region was affected in 47 patients (31.8%), two body regions were affected in 50 patients (33.8%), and ≥3 body regions were affected in 51 patients (34.3%). In a subset analysis, we identified that oxygen saturation |
