Introduction: Evaluation of immediate total-body CT (iTBCT) scouts during primary trauma care could be clinically relevant for early detection and treatment of specific major injuries. The aim of this study was to determine the diagnostic usefulness of TBCT scouts in detecting life-threatening chest and pelvic injuries. Methods: All patients who underwent an iTBCT during their primary trauma assessment in one trauma center between April 2011 and November 2014 were retrospectively included. Two experienced trauma surgeons and two emergency radiologists evaluated iTBCT scouts with structured questionnaires. Inter-observer agreement and diagnostic properties were calculated for endotracheal tube position and identification of pneumo- and/or hemothorax and pelvic fractures. Diagnostic properties of iTBCT scouts for indication for chest tube placement and pelvic binder application were calculated in comparison to decision based on iTBCT. Results: In total 220 patients with a median age of 37 years (IQR 26–59) were selected with a median Injury Severity Score of 18 (IQR 9–27). There was moderate to substantial inter-observer agreement and low false positive rates for pneumo- and/or hemothorax and for severe pelvic fractures by iTBCT scouts. For 19.8%–22.5% of the endotracheal intubated patients trauma surgeons stated that repositioning of the tube was indicated. Positive predictive value and sensitivity were respectively 100% (95%CI 52%–100%) and 50% (95%CI 22%–78%) for decisions on chest tube placement by trauma surgeon 1 and 67% (95%CI 13%–98%) and 22% (95%CI 4%–60%) for decisions by trauma surgeon 2. Only in one of 14 patients the pelvic binder was applied after iTBCT acquisition. Conclusions: iTBCT scouts can be useful for early detection of pneumo- and/or hemothorax and severe pelvic fractures. Decision for chest tube placement based on iTBCT scouts alone is not recommended.

Objectives: Initial trauma care could potentially be improved when conventional imaging and selective CT scanning is omitted and replaced by immediate total-body CT (iTBCT) scanning. Because of the potentially increased radiation exposure by this diagnostic approach, proper selection of the severely injured patients is mandatory. Methods: In the REACT-2 trial, severe trauma patients were randomized to iTBCT or conventional imaging and selective CT based on predefined criteria regarding compromised vital parameters, clinical suspicion of severe injuries, or high-risk trauma mechanisms in five trauma centers. By logistic regression analysis with backward selection on the 15 study inclusion criteria, a revised set of criteria was derived and subsequently tested for prediction of severe injury and shifts in radiation exposure. Results: In total, 1083 patients were enrolled with median ISS of 20 (IQR 9–29) and median GCS of 13 (IQR 3–15). Backward logistic regression resulted in a revised set consisting of nine original and one adjusted criteria. Positive predictive value improved from 76% (95% CI 74–79%) to 82% (95% CI 80–85%). Sensitivity decreased by 9% (95% CI 7–11%). The area under the receiver operating characteristics curve remained equal and was 0.80 (95% CI 0.77–0.83), original set 0.80 (95% CI 0.77–0.83). The revised set retains 8.78 mSv (95% CI 6.01–11.56) for 36% of the non-severely injured patients. Conclusions: Selection criteria for iTBCT can be reduced from 15 to 10 clinically criteria. This improves the positive predictive value for severe injury and reduces radiation exposure for less severely injured patients. Key Points: • Selection criteria for iTBCT can be reduced to 10 clinically useful criteria. • This reduces radiation exposure in 36% of less severely injured patients. • Overall discriminative capacity for selection of severely injured patients remained equal.

Background: Immediate total-body CT (iTBCT) is often used for screening of potential severely injured patients. Patients requiring emergency bleeding control interventions benefit from fast and optimal trauma screening. The aim of this study was to assess whether an initial trauma assessment with iTBCT is associated with lower mortality in patients requiring emergency bleeding control interventions. Methods: In the REACT-2 trial, patients who sustained major trauma were randomized for iTBCT or for conventional imaging and selective CT scanning (standard workup; STWU) in five trauma centers. Patients who underwent emergency bleeding control interventions following their initial trauma assessment with iTBCT were compared for mortality and clinically relevant time intervals to patients that underwent the initial trauma assessment with the STWU. Results: In the REACT-2 trial, 1083 patients were enrolled of which 172 (

The introduction of multi-slice CT scanners and infrastructural improvements made total-body CT scanning technically feasible and its usage is currently becoming common practice in several trauma centers. However, literature provides limited evidence whether immediate total-body CT leads to better clinical outcome then conventional radiographic imaging supplemented with selective CT scanning in trauma patients. The aim of the REACT-2 trial is to determine the value of immediate total-body CT scanning in trauma patients. METHODS/DESIGN: The REACT-2 trial is an international, multicenter randomized clinical trial. All participating trauma centers have a multi-slice CT scanner located in the trauma room or at the Emergency Department (ED). All adult, non-pregnant, severely injured trauma patients according to predefined criteria will be included. Patients in whom direct scanning will hamper necessary cardiopulmonary resuscitation or who require an immediate operation because of imminent death (both as judged by the trauma team leader) are excluded. Randomization will be computer assisted. The intervention group will receive a contrast-enhanced total-body CT scan (head to pelvis) during the primary survey. The control group will be evaluated according to local conventional trauma imaging protocols (based on ATLS guidelines) supplemented with selective CT scanning. Primary outcome will be in-hospital mortality. Secondary outcomes are differences in mortality and morbidity during the first year post trauma, several trauma work-up time intervals, radiation exposure, general health and quality of life at 6 and 12 months post trauma and cost-effectiveness. DISCUSSION: The REACT-2 trial is a multicenter randomized clinical trial that will provide evidence on the value of immediate total-body CT scanning during the primary sur
