Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
However, literature provides limited evidence whether immediate 'total body' CT scanning 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 TBCT scanning in trauma patients.
The investigators hypothesize that immediate 'total body' CT scanning during the primary survey of severely injured trauma patients has positive effects on patient outcome compared with standard conventional ATLS based radiological imaging supplemented with selective CT scanning.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Specialized trauma centers all over the world provide initial trauma care and diagnostic work-up of trauma patients. This work-up is standardized and frequently based on the Advanced Trauma Life Support (ATLS) guidelines which include a fast and priority-based physical examination as well as screening radiographs supplemented with selective Computed Tomography scanning (CT). ATLS guidelines advise to routinely perform X-rays of thorax and pelvis and Focused Assessment with Sonography for Trauma (FAST) in trauma patients. Whether or not to perform CT scanning following conventional imaging is defined less clearly in the ATLS guidelines and depends upon national guidelines and local protocols.
In recent years CT scanning has become faster, more detailed and more available in the acute trauma care setting. CT shows high accuracy for a wide range of injuries which is reflected by a low missed diagnosis rate. Hence, the conventional radiological work-up according to the ATLS may not be the optimal choice of primary diagnostics anymore. Furthermore, severely injured patients frequently require secondary CT scanning of many parts of the body after conventional imaging. Modern multidetector CT scanners (MDCT) can perform imaging of the head, cervical spine, chest, abdomen and pelvis in a single examination ('total body' CT scanning). The past few years this 'total body' imaging concept gained popularity as a possible alternative to the conventional imaging strategy. With the use of immediate 'total body' CT (TBCT) scanning in trauma patients, rapid and detailed information of organ and tissue injury becomes available and a well-founded plan for further therapy can be made.
In the past, CT scanners were located in the radiology department, frequently even on another floor than the emergency department (ED) were the trauma patient is admitted. The past assumption that TBCT in severely injured trauma patients is too time consuming may no longer be held, since an increasing number of trauma centers have a CT scanner available at the ED or even in the trauma room itself. Several studies evaluated time intervals associated with TBCT usage in severely injured patients. Although these studies are incomparable with respect to design, CT scanners used, diagnostic work-up protocols and trauma populations, the main conclusion is clear. TBCT scanning in trauma patients is not as time consuming as was once expected and may even be time saving compared to conventional imaging protocols supplemented with selective CT.
More and more trauma centers encourage and are implementing immediate TBCT scanning in the diagnostic phase of primary trauma care. Since the burden of TBCT in terms of costs and radiation dose is at least controversial, the advantage of performing immediate TBCT should be proven in high quality studies resulting in high level evidence in order to make its implementation justifiable.
In order to assess the value of immediate TBCT scanning in severely injured trauma patients, the Academic Medical Center (AMC) in Amsterdam, the Netherlands, has initiated an international multicenter randomized clinical trial. Severely injured patients, who are thought to benefit the most from a 'total body' imaging concept, will be included.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Conventional imaging
The control group will be evaluated with X-rays, ultrasonography and selective CT scanning.
Conventional imaging and selective CT scanning.
The control group will be evaluated according to a conventional trauma protocol with X-rays (of the chest and pelvis), ultrasonography (Focused Assessment with Sonography for Trauma (FAST)) and selective CT scanning.
Indications for the selective CT scanning are pre-defined and based on the combined local protocols of the participating centers.
Immediate total body CT
The intervention group will receive a 'total body' CT scan from head to pelvis. Conventional radiography and FAST will be completely omitted.
Total body Computed Tomography.
The CT protocol for the intervention group consists of a two-step whole-body acquisition (from vertex to pubic symphysis) starting with Head and Neck Non Enhanced CT (NECT) with arms alongside the body.
The preferred technique for the second complementary scan is a split-bolus intravenous contrast directly after repositioning of the arms alongside the head, and this second scan covers thorax, abdomen and pelvis. Participating centers however are free to choose their own technique as long as intravenous contrast is given for the chest and abdominal part of the TBCT.
