Re-thinking the value of cross-sectional torso imaging for ground-level fall patients with altered mental status: Outcomes from a level 1 trauma center. Injury 2024; 55:111239. [PMID: 38071125 DOI: 10.1016/j.injury.2023.111239] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/21/2023] [Revised: 10/29/2023] [Accepted: 11/24/2023] [Indexed: 12/24/2023]
Abstract
INTRODUCTION Patients with altered mental status (AMS) are often excluded from studies evaluating the utility of computed tomography of the torso (CTT) after ground level falls (GLF). It is not known whether CTT identifies otherwise undetectable injuries in patients with AMS after GLF. We sought to describe the value of performing CTT in patients with AMS after GLF, and hypothesized that CTT would not identify new, clinically significant injuries in patients with a normal torso physical exam (PE) and normal chest and pelvic radiographs (CXR/PXR). METHODS Single-institution retrospective cohort study of GLF patients (≤1 m) with and without AMS (GCS <15, blood alcohol level >150 mg/dL, intubation prior to hospital evaluation), 2015-2019. Traumatic injury identification on CTT was evaluated in the context of normal/abnormal torso PE (based on provider documentation) and normal CXR/PXR. RESULTS 1195 patients met inclusion criteria; 344 had AMS, of which 129 (37.5 %) underwent CTT. A further 851 patients had normal mental status, of which 180 (21.2 %) underwent CTT. Patients with a normal PE with AMS (N = 79) and without AMS (N = 38) had a similar rate of new injury discovery on CTT (6.3% vs. 7.9 %, p = 1.00). Negative PE had a negative predictive value (NPV) for identification of a new, acute traumatic injury of 92.4 % (95 % CI: 0.84-0.96) in patients with AMS while normal PE, CXR, and PXR had a NPV of 96.0 % (95 % CI: 0.80-0.99). Among patients with CTT, patients with AMS had a significantly lower rate of acute traumatic injury on CTT compared to alert patients (26.4 % vs. 48.9 %, p < 0.001). On multivariate analysis, AMS was not positively associated with likelihood of identifying acute traumatic injury on CTT. CONCLUSIONS In patients sustaining GLFs who present with AMS and who otherwise have a negative PE, CXR, and PXR, CTT is very unlikely to identify new traumatic injuries. Strong consideration should be given to forego cross-sectional imaging in this patient population.

Zhu M, O'Brien M, Shaikh SP, Brahmbhatt TS, LeBedis C, Scantling D, Sanchez SE. Utilization of torso computed tomography for the evaluation of ground level falls: More imaging does not equal better care. Injury 2023; 54:105-111. [PMID: 36470767 DOI: 10.1016/j.injury.2022.11.051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Revised: 11/11/2022] [Accepted: 11/23/2022] [Indexed: 11/30/2022]
Abstract
INTRODUCTION Computed tomography (CT) of the chest (CTC), abdomen, and pelvis (CTAP) is common when assessing trauma patients in the emergency department. However, unnecessary imaging can expose patients to unneeded radiation and increase healthcare costs. Here, we characterize the use of torso CT imaging for the evaluation of ground level falls (GLF) at a single level 1 trauma center. PATIENTS AND METHODS We conducted a retrospective review of all patients ≥18 years old presenting to a single level 1 trauma center with a GLF (1m or less) in 2015-2019. Data were obtained through chart review. Descriptive statistics were used to summarize patient characteristics. Multivariable logistic regression was used to assess factors leading to patients obtaining torso CT imaging. The utility of CT imaging in identifying injuries that changed management was also evaluated. RESULTS Of the 1,195 patients captured during the study period, 492 patients had a positive torso physical exam (PE), and 703 had a negative torso PE. Of patients with a negative torso PE, 127 CTC and 142 CTAP were obtained, with only 5.5% CTC identifying traumatic injuries not previously diagnosed on chest radiograph (CXR), and only 0.7% CTAP identifying new injuries not identified on pelvic radiograph (PXR). Multivariable logistic regression demonstrated that only a positive PE was significantly associated with the identification of abnormal imaging findings on torso CT. A negative PE, CXR, and PXR have a negative predictive value of 98%. DISCUSSION These data suggest that patients with a negative PE, even if intoxicated, intubated, or with a decreased GCS, are highly unlikely to have new, clinically relevant findings on torso CT imaging. CONCLUSION Using PE, CXR, and PXR as a screening tool in patients sustaining GLF, which if negative close to obviates the need for torso CT, may reduce healthcare costs and radiation exposure without compromising patient care.

Changing the Patient's Position: Pitfalls and Benefits for Radiation Dose and Image Quality of Computed Tomography in Polytrauma. Diagnostics (Basel) 2022; 12:diagnostics12112661. [PMID: 36359504 PMCID: PMC9689596 DOI: 10.3390/diagnostics12112661] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2022] [Revised: 10/28/2022] [Accepted: 10/29/2022] [Indexed: 11/06/2022] Open
Abstract
For computed tomography (CT), representing the diagnostic standard for trauma patients, image quality is essential. The positioning of the patient’s arms next to the abdomen causes artifacts and is also considered to increase radiation exposure. The aim of this study was to evaluate the effect of various positionings during different CT examination steps on the extent of artifacts as well as radiation dose using iterative reconstruction (IR). 354 trauma-CTs were analyzed retrospectively. All datasets were reconstructed using IR and three different examination protocols were applied. Arm elevation led to a significant improvement of the image quality across all examination protocols (p < 0.001). Variation in arm positioning during image acquisition did not lead to a reduction of radiation dose (p = 0.123). Only elevation during scout acquisition resulted in the reduction of radiation exposure (p < 0.001). To receive high-quality CT images, patients should be placed with elevated arms for the trunk scan, as artifacts remain even with the IR. Arm repositioning during the examination itself had no effect on the applied radiation dose because its modulation refers to the initial scout obtained. In order to achieve a dose effect by different positioning, a two-scout protocol (dual scout) should be used.

Abstract
Major trauma is an event causing injuries that may determine an immediate or potential risk to the patient survival. A correct management of major trauma is decisive in reducing disability, which has relevance both from the point of view of the quality of life of the single individual and from the point of view of health expenditure. The primary clinical approach to the polytraumatized patients is managed, in most cases, as outlined in the guidelines of Advanced Trauma Life Support, proposing conventional radiological investigations, such as chest and pelvis x-ray, and of FAST (focused abdominal sonography in trauma)/E-FAST (extended FAST) examinations, followed by selective targeted computed tomography (CT). This approach is questionable and is increasingly common in clinical practice the adoption of the immediate total-body CT in the diagnostic approach to the hemodynamically stable polytraumatized patient. However, the potential advantages of such conduct both in terms of clinical benefits and in terms of cost-effectiveness still need to be discussed. The objective of this review article consists of a descriptive analysis of the economic and clinical benefits of the adoption of immediate total-body CT in polytrauma patients through a literature review.

Assessment of Rib Fracture in Acute Trauma Using Automatic Rib Segmentation and a Curved, Unfolded View of the Ribs: Is There a Saving of Time? J Clin Med 2022; 11:jcm11092502. [PMID: 35566629 PMCID: PMC9101064 DOI: 10.3390/jcm11092502] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2022] [Revised: 04/23/2022] [Accepted: 04/27/2022] [Indexed: 02/04/2023] Open
Abstract
Introduction: The fast and accurate diagnosis of rib fractures in polytrauma patients is important to reduce the mortality rate and relieve long-term pain and complications. Aim: To evaluate the diagnostic accuracy and potential time savings using automatic rib segmentation and a curved, unfolded view for the detection of rib fractures in trauma patients. Methods: The multidetector computed tomography raw data of 101 consecutive polytrauma patients (72 men; mean age 45 years, age range 17 to 84 years) admitted to a university hospital were retrospectively post-processed to generate a curved, unfolded view of the rib cage. No manual corrections were performed. Patients with reconstruction errors and movement artifacts were excluded from further analysis. All fractures were identified and classified by the study coordinator using the original data set. Two readers (reader 1 and reader 2) evaluated the original axial sections and the unfolded view, separately. The fracture locations, fracture type, and reading times were recorded. Sensitivity and specificity were calculated on a per-rib basis using a ratio estimator. Cohen’s Kappa was calculated as an index of inter-rater agreement. Results: 26 of 101 patients (25.7%) were excluded from further analysis owing to breathing artifacts (6.9%) or incorrect centerline computation in the unfolded view (18.8%). In total, 107 (5.9%) of 1800 ribs were fractured in 25 (33%) of 75 patients. The unfolded view had a sensitivity/specificity of 81%/100% (reader 1) and 71%/100% (reader 2) compared to 94%/100% (reader 1; p = 0.002/p = 0.754) and 63%/99% (reader 2; p < 0.001/p = 0.002). The sensitivity (reader 1; reader 2) was poor for buckled fractures (31%; 38%), moderate for undislocated fractures (78%; 62%), and good for dislocated fractures (94%; 90%). The assessment of the unfolded view was performed significantly faster than that of the original layers (19.5 ± 9.4 s vs. 68.6 ± 32.4 s by reader 1 (p < 0.001); 24.1 ± 9.5 s vs. 40.2 ± 12.7 s by reader 2 (p < 0.001)). Both readers demonstrated a very high interobserver agreement for the unfolded view (κ = 0.839) but only a moderate agreement for the original view (κ = 0.529). Conclusion: Apart from a relatively high number of incorrect centerline reconstructions, the unfolded view of the rib cage allows a faster diagnosis of dislocated rib fractures.

Automated CT reformations reduce time and variability in trauma panscan exam completion. Emerg Radiol 2022; 29:461-469. [PMID: 35237937 DOI: 10.1007/s10140-022-02031-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2021] [Accepted: 02/09/2022] [Indexed: 10/19/2022]
Abstract
PURPOSE To test the hypothesis that an automated post-processing workflow reduces trauma panscan exam completion times and variability. METHODS One-hundred-fifty consecutive trauma panscans performed between June 2018 and December 2019 were included, half before and half after implementation of an automated software-driven post-processing workflow. Acquisition and reconstruction timestamps were used to calculate total examination time (first acquisition to last reformation), setup time (between the non-contrast and contrast-enhanced acquisitions), and reconstruction time (for the contrast-enhanced reconstructions and reformations). The performing technologist was recorded and accounted for in analyses using linear mixed models to assess differences between the pre- and post-intervention groups. RESULTS Exam, setup, and recon times were (mean ± standard deviation) 33.5 ± 4.6, 9.2 ± 2.4, and 23.6 ± 4.7 min before and 27.8 ± 1.5, 8.9 ± 1.4, and 18.9 ± 1.7 min after intervention. These reductions of 5.7 and 4.7 min in the mean exam and recon times were statistically significant (p < 0.001) while the setup time was not (p = 0.49). The reductions in standard deviation were statistically significant for exam and recon times (p < 0.0001) but not for setup time (p = 0.13). All automated panscans were completed within 36 min, versus 65% with the traditional workflow. CONCLUSION Automation of image reconstruction workflow significantly decreased mean exam and reconstruction times as well as variability between exams, thus facilitating a consistently rapid imaging assessment, and potentially reducing delays in critical management decisions.

Abstract
PURPOSE To examine the relationship between superficial lesions (such as bruises, hematomas, deep abrasions, and soft tissue emphysema) and internal post-traumatic injuries, assessed using whole-body computed tomography (WBCT), and to determine if these are valid markers for internal injuries. METHODS AND MATERIALS 250 patients who underwent WBCT emergency scans for suspected polytrauma were retrospectively analyzed after institutional review board approval of the study. The scans were carried out on patients who met the criteria for standard operating procedures for WBCT emergency scans. WBCT covering the entire head, neck, chest, and abdomen (including pelvis and proximal lower extremities) and at least one phase with intravenous contrast agent were included in the study. Initial analyses of immediate WBCT scans was carried out by a consultant radiologist and a radiological resident. The first reading focused on internal damage that needed immediate therapy. The second reading focused on a detailed analysis of the skin and subcutaneous tissue and their relation to internal injuries without the time pressure of an emergency setting, carried out by another experienced radiologist. All skin lesions and the degree of penetration and a comparison between the two readings were reported in tables. RESULTS Superficial lesion of the chest was detected in 19 patients, 17 of them had an internal injury of the thorax while only two patients, with hematoma of the chest wall, had no internal injuries. Skin and subcutaneous lesions of the chest had the strongest association with an internal injury. Skin lesions of the abdominal wall were observed in 30 patients. In only 11 cases, these lesions were correlated with internal injuries, such as fractures or active bleeding. 52 skin and subgaleal lesions of the scalp were observed. In 20 of these patients, an intracranial or internal injury was detected. In 3 patients, skin abrasions of the neck were present and in only one of them, this finding was associated with an internal injury. CONCLUSION Trauma patients whose history and clinical presentation meet the standard operating procedures for WBCT emergency scans and who present with a cutaneous lesion, especially at the neurocranium or chest wall, should be observed for internal injuries by WBCT. KEY POINTS · Presence or lack of a superficial injury of the abdominal wall is not a reliable predictive indication of any internal abdominal injury.. · Superficial lesions of the chest and the neurocranium require a CT scan.. · Superficial injuries of the chest wall had the strongest association with internal injuries..

Abstract
BACKGROUND Severe traumatic injury continues to present challenges to healthcare systems around the world, and post-traumatic bleeding remains a leading cause of potentially preventable death among injured patients. Now in its fifth edition, this document aims to provide guidance on the management of major bleeding and coagulopathy following traumatic injury and encourages adaptation of the guiding principles described here to individual institutional circumstances and resources. METHODS The pan-European, multidisciplinary Task Force for Advanced Bleeding Care in Trauma was founded in 2004, and the current author group included representatives of six relevant European professional societies. The group applied a structured, evidence-based consensus approach to address scientific queries that served as the basis for each recommendation and supporting rationale. Expert opinion and current clinical practice were also considered, particularly in areas in which randomised clinical trials have not or cannot be performed. Existing recommendations were re-examined and revised based on scientific evidence that has emerged since the previous edition and observed shifts in clinical practice. New recommendations were formulated to reflect current clinical concerns and areas in which new research data have been generated. RESULTS Advances in our understanding of the pathophysiology of post-traumatic coagulopathy have supported improved management strategies, including evidence that early, individualised goal-directed treatment improves the outcome of severely injured patients. The overall organisation of the current guideline has been designed to reflect the clinical decision-making process along the patient pathway in an approximate temporal sequence. Recommendations are grouped behind the rationale for key decision points, which are patient- or problem-oriented rather than related to specific treatment modalities. While these recommendations provide guidance for the diagnosis and treatment of major bleeding and coagulopathy, emerging evidence supports the author group's belief that the greatest outcome improvement can be achieved through education and the establishment of and adherence to local clinical management algorithms. CONCLUSIONS A multidisciplinary approach and adherence to evidence-based guidance are key to improving patient outcomes. If incorporated into local practice, these clinical practice guidelines have the potential to ensure a uniform standard of care across Europe and beyond and better outcomes for the severely bleeding trauma patient.

Abstract
PURPOSE To compare thick (5 mm) and thin slice images (1.5 mm) of lung, soft tissue, and bone window in thoracoabdominal trauma computed tomography. MATERIALS AND METHODS 167 Patients that underwent thoracoabdominal trauma CT between November 2014 and December 2015 were included in the study. CT data were reconstructed in a transverse direction with 5 mm and 1.5 mm slice images of lung, soft tissue, and bone window. Two blinded raters (radiologists) evaluated the collected data by detecting predefined injuries in different organ areas. Reconstruction and evaluation times as well as detected injuries were noted and compared. RESULTS Reconstruction and evaluation times were significantly higher with 1.5 mm thin-slice images, and the effect strength according to Rosenthal displayed a strong effect of 0.61 (< 0.1 small effect, 0.3 middle effect, and > 0.5 strong effect). Average evaluation time differences were 62.7 s (33.9 s-91.5 s) in bone window between 1.5 mm and 3 mm for rater 1 (p < 0.001) and 71.4 s (43.1 s-99.7 s) for rater 2 (p < 0.001). Average time differences between 1.5 mm and 5 mm were 68,7 s (43.9 s-93.5 s) for rater 1 and 75.3 s (44.7 s-105.9 s) for rater 2 in lung window (p < 0.001) and 66.6 s (28.8 s-104.4 s) for rater 1 and 114 s (74.4 s-153.6 s) for rater 2 in soft-tissue window (p < 0.001). There was no significant difference regarding soft-tissue and lung injuries, except non-significant improvement in the detection of bone fractures. CONCLUSION Thin-slice images do not bring any significant benefit in thoracoabdominal trauma CT of soft-tissue and lung injuries, but they can be helpful for the diagnosis of bone fractures and incidental findings.

Abstract
Background Split-bolus computed tomography (CT) is a recent development in trauma imaging. Instead of multiple scans in different contrast phases after a single contrast bolus, split-bolus protocols consist of one single scan of the thorax and abdomen after two or three contrast injections at different points of time. Purpose To evaluate and compare image quality and injury findings of a new triple-split-bolus CT (TS-CT) protocol of thorax and abdomen with those of a portal venous phase CT (PV-CT) in the same patient group. Material and Methods Trauma patients in 2009-2012 who underwent both the TS-CT initially and a PV-CT during the next six weeks were included. The TS-CT examination was performed as one CT run after application of three contrast boluses (total 175 mL) to enhance renal pelvis and urinary tract, the abdominal organs, and the large arterial vessels. The PV-CT had a fixed delay of 85 s. We measured attenuation in Hounsfield units (HU), evaluated possible organ injury and assessed image quality on a 5-point scale. Results Thirty-five patients were included. Attenuation measurements of major abdominal vessels, organs, and renal pelvis were significantly higher with the TS-CT protocol. Performance in organ injury diagnosis and image quality was equal in both protocols. Conclusion The overall performance of the TS-CT protocol is similar to the standard PV-CT. Excellent visualization of the arterial tree and the collecting system may eliminate the need for separate scans.

Abstract
Routine full-body CT "pan-scan" use in older patients after ground level falls (GLFs) is of questionable benefit. Retrospective review of new diagnosis & changes in management in patients >55 years with Glasgow Coma Scale of 15 after a GLF who received a pan-scan (routine head, cervical spine/neck, chest abdomen, and pelvis CT). Head CT results were considered separately; results described in the following paragraph pertains to cervical spine/neck, chest, abdomen, and pelvis CT. One hundred and fifty-two patients received pan-scans; 96 (63%) had new findings. Thirty-five (23%) resulted in a minor change and three (2%) in a major change in management, defined as a procedural intervention. This included tube thoracostomy in one patient and cervical spine surgery in two. A further eight patients required the use of a cervical collar. In all patients requiring intervention, there were clinical signs present that should have led to directed CT scan of area of concern. Routine pan-scans in stable, alert older patients after a GLF result in new findings in most patients, with primarily nonprocedural interventions for these additional findings.

Abstract
BACKGROUND AND PURPOSE In patients with hemorrhagic contusions, hematoma volumes are overestimated on follow-up standard 120-kV images obtained after contrast-enhanced whole-body CT. We aimed to retrospectively determine hemorrhagic progression of contusion rates on 120-kV and 190-keV images derived from dual-energy CT and the magnitude of hematoma volume overestimation. MATERIALS AND METHODS We retrospectively analyzed admission and follow-up CT studies in 40 patients with hemorrhagic contusions. After annotating the contusions, we measured volumes from admission and follow-up 120-kV and 190-keV images using semiautomated 3D segmentation. Bland-Altman analysis was used for hematoma volume comparison. RESULTS On 120-kV images, hemorrhagic progression of contusions was detected in 24 of the 40 patients, while only 17 patients had hemorrhagic progression of contusions on 190-keV images (P = .008). Hematoma volumes were systematically overestimated on follow-up 120-kV images (9.68 versus 8 mm3; mean difference, 1.68 mm3; standard error, 0.37; P < .001) compared with 190-keV images. There was no significant difference in volumes between admission 120-kV and 190-keV images. Mean and median percentages of overestimation were 29% (95% CI, 18-39) and 22% (quartile 3 - quartile 1 = 36.8), respectively. CONCLUSIONS The 120-kV images, which are comparable with single-energy CT images, significantly overestimated the hematoma volumes, hence the rate of hemorrhagic progression of contusions, after contrast-enhanced whole-body CT. Hence, follow-up of hemorrhagic contusions should be performed on dual-energy CT, and 190-keV images should be used for the assessment of hematoma volumes.

Variability in CT imaging of blunt trauma among ED physicians, surgical residents, and trauma surgeons. J Surg Res 2017; 213:6-15.

Abstract
BACKGROUND Trauma triage decisions can be influenced by both knowledge and experience. Consequently, there may be substantial variability in computed tomography (CT) scans desired by emergency medicine physicians, surgical chief residents, and attending trauma surgeons. We quantified this difference and studied the effects of each group's decisions on missed injuries, cost, and radiation exposure. METHODS All blunt trauma activations at an urban level 1 trauma center were studied over a 6-mo period. Three months into the study, a pan-scan protocol was introduced. Prior to CT imaging, providers separately completed a survey that asked which CT scans were desired for each patient. Based on the completed surveys, hypothetical missed injuries, radiation exposure, and cost were determined. RESULTS The variability in the number of CT scans desired by each of the three providers and the resulting cost and radiation exposure were not statistically significant. Substantial variability was predominantly seen in the indications for the desired scans, with the difference between proportions ranging from 3.1%-68.7%. Agreement among the three providers was highest for head and c-spine scans (80%-100%) and lowest for maxillary face (57%-80%) and chest scans (52%-74%). Overall, the missed injury rate was similar for all the providers; chief residents missed significantly more major injuries than trauma attendings during the pan-scan period (P = 0.03). CONCLUSIONS Trauma training and level of training did not have a substantial effect on radiological decisions during the initial trauma assessment. This study sheds light on the growing uniformity among providers with regard to medical decision-making in the initial work-up of trauma.

Abstract
The indications of point-of-care ultrasound (POCUS) in the management of multiple trauma patients have been expanding. Although computed tomography (CT) scan of the orbit remains the gold standard for imaging orbital trauma, ultrasound is a quick, safe, and portable tool that can be performed bedside. Here we report two patients who had severe eye injuries with major visual impairment where surgeon-performed POCUS was very useful. One had a foreign body injury while the other had blunt trauma. POCUS was done using a linear probe under sterile conditions with minimum pressure on the eyes. Ultrasound showed a foreign body at the back of the left eye globe touching the eye globe in the first patient, and was normal in the second patient. Workup using CT scan, fundsocopy, optical coherence tomography, and magnetic resonance imaging of the orbits confirmed these findings. The first patient had vitreous and sub retinal haemorrhage and a full thickness macular hole of the left eye, while the second had traumatic optic neuropathy. POCUS gave accurate information concerning severe eye injuries. Trauma surgeons and emergency physicians should be trained in performing ocular ultrasound for eye injuries.

Abstract
Addenbrooke's Hospital, the Major Trauma Centre for the East of England Trauma Network, received 1070 major trauma patients between 1st January and 31st December 2014. In order to improve care, an audit was performed of 59 patients meeting our own selection criteria for orthopaedic polytrauma between 1st January 2013 and 31st December 2013. The Cambridge Polytrauma Pathway was devised through NCEPOD guidelines, literature review, internal and external discussion. It facilitates provision of best practice Early Appropriate Care, encompassing - multidisciplinary consultant decisions around the patient in our Neurological and Trauma Critical Care Unit, early full body trauma CT scans, serial measurements of lactate and fibrinogen levels, and out-of-hours orthopaedic theatre reserved for life-and-limb threatening injuries. Re-audit was conducted of 15 patients meeting selection criteria, admitted between 1st October 2014 and 31st March 2015. Significant improvements in recording of lactate and fibrinogen were demonstrated, both on admission (lactate - p<0.000, fibrinogen - p=0.015), and preoperatively (lactate - p=0.003, fibrinogen - p=0.030). Time to trauma CT was unchanged (p=0.536) with a median time to CT of 0.53h at re-audit (IQR 0.48-0.75). The number of patients receiving definitive orthopaedic intervention out-of-hours reduced from 8 to zero (p=0.195). The approach of facilitating management decisions to be made at early daytime MDT meetings has been adopted. It is anticipated that this pathway will improve outcomes in orthopaedic polytrauma patients and it is recommended that either the GOS-E, or the EQ-5D scoring systems be introduced to assess this.

Abstract
Serious multiple traumatic injuries may rapidly become fatal or be complicated by a life-threatening sequelae leading to a significant increase of the mortality rate. Trauma scoring systems are used to evaluate the critical status of the patient and recently many different biomarkers have been taken into account to better estimate the potential clinical outcome. The aim of the present study is to analyse the expression pattern of high-mobility group box-1 (HMGB1), oxidative stress markers and nuclear factor erythroid 2-related (Nrf2) in critically ill traumatic patients (at hospital admittance and after 6 and 24 h), in order to find out their potential role as early post-traumatic predictors markers. Forty-seven patients admitted for multiple trauma and 15 healthy participants were prospectively recruited. Eight patients (17%) died within 92 h of admission; this subgroup of patients presented the highest severity scores and their HMGB1 expression levels were significantly correlated with ISS, whereas patients with higher ISS exhibited higher levels of HMGB1 (P <0.001). Our study suggests the role of HMGB1 as a predictive biomarker of outcome in injured patients and hypothesizes the protective role of Nrf2 in bringing down the oxidative stress and HMGB1 release; measuring HMGB1 in combination with Nrf2 might represent a potentially useful tool in the early detection of post-trauma complications.
