Abstract
BACKGROUND Acute colonic pseudo-obstruction (ACPO) is characterized by severe colonic distension without mechanical obstruction. It has an uncertain pathogenesis and poses diagnostic challenges. This study aims to explore risk factors and clinical outcomes of ACPO in polytrauma patients, and contributing information to the limited literature on this condition. METHODS This retrospective study, conducted at a Level 1 Trauma Centre, analysed data from trauma patients with ACPO admitted between July 2009 and June 2018. A control cohort of major trauma patients was utilized. Data review encompassed patient demographics, abdominal imaging, injury characteristics, analgesic usage, interventions, complications, and mortality. Statistical analyses, including logistic regression and correlation coefficients, were employed to identify risk factors. RESULTS There were 57 cases of ACPO, with an incidence of 1.7 / 1000 patients, rising to 4.86 in major trauma. Predominantly affecting those over 50 years of age (75%) and males (75%), with motor vehicle accidents (50.8%) and falls from height (36.8%) being the commonest mechanisms. Noteworthy associated injuries included retroperitoneal bleeds (RPB) (37%), spinal fractures (37%), and pelvic fractures (37%). Analysis revealed significant associations between ACPO and Shock Index >0.9, Injury Severity Score > 18, opioid use, RPB, and pelvic fractures. A caecal diameter of ≥12 cm had a significant association with caecal ischemia or perforation. CONCLUSION This study underscores the significance of ACPO in polytrauma patients, demonstrating associations with risk factors and clinical outcomes. Clinicians should maintain a high index of suspicion, particularly in older patients with RPB, pelvic fractures, and opioid use. Early supportive therapy, vigilant monitoring, and timely interventions are crucial for a favourable outcome. Further research and prospective trials are warranted to validate these findings and enhance understanding of ACPO in trauma patients. LEVEL OF EVIDENCE Prognostic and Epidemiological, Level IV.

The GCS-Pupils (GCS-P) score to assess outcomes after traumatic brain injury: a retrospective study. Br J Neurosurg 2024:1-4. [PMID: 38259200 DOI: 10.1080/02688697.2023.2301071] [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: 06/07/2023] [Accepted: 12/21/2023] [Indexed: 01/24/2024]
Abstract
INTRODUCTION The Glasgow Coma Scale (GCS) and pupil response to light are commonly used to assess brain injury severity and predict outcomes. The aim of this study was to investigate whether the GCS combined with pupil response (GCS-P), compared to the GCS alone, could be a better predictor of hospital mortality for patients with traumatic brain injury (TBI). METHODS A retrospective cohort study was undertaken at an adult level one trauma centre including patients with isolated TBI of Abbreviated Injury Scale above three. The GCS and pupil response were combined to an arithmetic score (GCS score (range 3-15) minus the number of nonreacting pupils (0, 1, or 2)), or by treating each factor as separate categorical variables. The association of in-hospital mortality with GCS-P as a categorical variable was evaluated using Nagelkerke's R2 and compared using areas under the receiver operating characteristic (AUROC) curve. RESULTS There were 392 patients included over the study period of 1 July 2014 and 30 September 2017, with an overall mortality rate of 15.2%. Mortality was highest at GCS-P of 1 (79%), with lowest mortality at a GCS-P 15 (1.6%). Nagelkerke's R2 was 0.427 for GCS alone and 0.486 for GCS-P. The AUROC for GCS-P to predict mortality was 0.87 (95%CI: 0.82-0.72), higher than for GCS alone (0.85; 95%CI: 0.80-0.90; p < .001). DISCUSSION GCS-P provided a better predictor of mortality compared to the GCS. As both the GCS and pupillary response are routinely recorded on all patients, combination of these pieces of information into a single score can further simplify assessment of patients with TBI, with some improvement in performance.

Abstract
BACKGROUND Up to 25% of trauma deaths are related to thoracic injuries. OBJECTIVE The primary goal was to analyse the incidence and time distribution of death in adult patients with major thoracic injuries. The secondary goal was to determine if potentially preventable deaths occurred within this time distribution and, if so, identify an associated therapeutic window. DESIGN Retrospective observational analysis. SETTING TraumaRegister DGU. PATIENTS Major thoracic injury was defined as an Abbreviated Injury Scale (AIS) 3 or greater. Patients with severe head injury (AIS ≥ 4) or injuries to other body regions with AIS being greater than the thoracic injury (AIS other >AIS thorax) were excluded to ensure that the most severe injury described was primarily thoracic related. MAIN OUTCOME MEASURES Incidence and time distribution of mortality were considered the primary outcome measures. Patient and clinical characteristics and resuscitative interventions were analysed in relation to the time distribution of death. RESULTS Among adult major trauma cases with direct admission from the accident scene, 45% had thoracic injuries and overall mortality was 9.3%. In those with major thoracic trauma ( n = 24 332) mortality was 5.9% ( n = 1437). About 25% of these deaths occurred within the first hour after admission and 48% within the first day. No peak in late mortality was seen. The highest incidences of hypoxia and shock were seen in non-survivors with immediate death within 1 h and early death (1 to 6 h). These groups received the largest number of resuscitative interventions. Haemorrhage was the leading cause of death in these groups, whereas organ failure was the leading cause of death amongst those who survived the first 6 h after admission. CONCLUSION About half of adult major trauma cases had thoracic injuries. In non-survivors with primarily major thoracic trauma, most deaths occurred immediately (<1h) or within the first 6 h after injury. Further research should analyse if improvements in trauma resuscitation performed within this time frame will reduce preventable deaths. TRIAL REGISTRATION The present study is reported within the publication guidelines of the TraumaRegister DGU® and registered as TR-DGU project ID 2020-022.

Hospitalisations and in-hospital deaths following moderate to severe traumatic brain injury in Australia, 2015-20: a registry data analysis for the Australian Traumatic Brain Injury National Data (ATBIND) project. Med J Aust 2023; 219:316-324. [PMID: 37524539 DOI: 10.5694/mja2.52055] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2022] [Revised: 06/26/2023] [Accepted: 06/29/2023] [Indexed: 08/02/2023]
Abstract
OBJECTIVE To describe the frequency of hospitalisation and in-hospital death following moderate to severe traumatic brain injury (TBI) in Australia, both overall and by patient demographic characteristics and the nature and severity of the injury. DESIGN, SETTING Cross-sectional study; analysis of Australia New Zealand Trauma Registry data. PARTICIPANTS People with moderate to severe TBI (Abbreviated Injury Score [head] greater than 2) who were admitted to or died in one of the twenty-three major Australian trauma services that contributed data to the ATR throughout the study period, 1 July 2015 - 30 June 2020. MAJOR OUTCOME MEASURES Primary outcome: number of hospitalisations with moderate to severe TBI; secondary outcome: number of deaths in hospital following moderate to severe TBI. RESULTS During 2015-20, 16 350 people were hospitalised with moderate to severe TBI (mean, 3270 per year), of whom 2437 died in hospital (14.9%; mean, 487 per year). The mean age at admission was 50.5 years (standard deviation [SD], 26.1 years), and 11 644 patients were male (71.2%); the mean age of people who died in hospital was 60.4 years (SD, 25.2 years), and 1686 deaths were of male patients (69.2%). The overall number of hospitalisations did not change during 2015-20 (per year: incidence rate ratio [IRR], 1.00; 95% confidence interval [CI], 0.99-1.02) and death (IRR, 1.00; 95% CI, 0.97-1.03). CONCLUSION Injury prevention and trauma care interventions for people with moderate to severe TBI in Australia reduced neither the incidence of the condition nor the associated in-hospital mortality during 2015-20. More effective care strategies are required to reduce the burden of TBI, particularly among younger men.

Alcohol-related trauma presentations among older teenagers. Emerg Med Australas 2023; 35:269-275. [PMID: 36316024 DOI: 10.1111/1742-6723.14109] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2022] [Revised: 10/02/2022] [Accepted: 10/02/2022] [Indexed: 11/29/2022]
Abstract
OBJECTIVE The objectives of the present study were to report the proportion of older teenagers, including the subgroup operating a motor vehicle, presenting to an adult major trauma centre after injury with a positive blood alcohol concentration (BAC) over a 12-year period. METHODS This was a registry-based cohort study, including all patients aged 16-19 years presenting to an adult major trauma centre in Victoria, Australia from January 2008 to December 2019 and included in the trauma registry. A Poisson regression model was used to test for change in incidence of positive BAC associated trauma and summarised using incidence rate ratios (IRRs) and 95% confidence intervals (CIs). RESULTS There were 1658 patients included for analysis and alcohol was detected in 368 (22.2%; 95% CI 20.2-24.3). Most alcohol positive presentations were on weekend days (n = 207; 56.3%) and most were males (n = 307). Over the 12-year period, there was a reduction in the incidence of older teenagers presenting with a positive BAC (IRR 0.95; 95% CI 0.93-0.98; P = 0.001). Among patients presenting after trauma in the setting of operating a motor vehicle (n = 545), alcohol was detected in 80 (14.7%) with no significant change in incidence of positive BAC (IRR 0.95; 95% CI 0.89-1.02; P = 0.17). CONCLUSIONS A substantial proportion of older teenagers included in the registry had alcohol exposure prior to trauma. Despite a modest down-trending incidence, the need for continuing preventive measures is emphasised. In particular, preventive efforts should be targeted at male, older teenagers undertaking drinking activities on weekend days and driving motor vehicles.

Interpretation of computed tomography of the cervical spine by non-radiologists: a systematic review and meta-analysis. ANZ J Surg 2023; 93:493-499. [PMID: 36129439 DOI: 10.1111/ans.18055] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2022] [Revised: 08/19/2022] [Accepted: 08/23/2022] [Indexed: 12/01/2022]
Abstract
BACKGROUND After trauma, clearance of the cervical spine refers to the exclusion of underlying serious injuries. Accurate assessment of computed tomography (CT) is commonly required prior to clearance of the cervical spine. Delays to clearance can lead to prolonged immobilization with associated patient discomfort and adverse effects. This systematic review aimed to determine performance of non-radiologists to evaluate cervical spine CT. METHODS MEDLINE, EMBASE, Cochrane library with sources of grey literature and reference lists of selected articles were appraised from inception to April 2021. We included manuscripts that reported discordance in CT cervical spine interpretation between non-radiologists and radiologists. The Newcastle-Ottawa scale (NOS) was used to assess quality of included studies and statistical heterogeneity was assessed using the I2 statistic. RESULTS There were 43 studies identified for eligibility and 4 manuscripts included in the final analysis. There were two studies that reported on the performance of radiology residents, one study on the performance of surgical residents and one on emergency physicians. The pooled discordance was 0.25 (95%CI 0.21-0.28) but was lower for radiology residents (range 0.007-0.05). There was significant statistical heterogeneity (I2 = 99.6%, P < 0.001) among studies. CONCLUSION There is a paucity of evidence documenting the ability of non-radiologists in accurately interpreting CT of the cervical spine. A number of discordant findings suggest that studies with larger sample sizes are indicated to accurately ascertain the ability of non-radiologists in this area.

Abstract
Haemorrhagic shock after trauma is a leading cause of death worldwide, particularly in young individuals. Despite advances in trauma systems and resuscitation strategies, mortality from haemorrhagic shock has not declined over the previous two decades. A proportion of shocked trauma patients may experience a deficiency of cortisol relative to the severity of their injury. The benefit of exogenous steroid administration in patients suffering haemorrhagic shock as a result of injury is unclear. A systematic review of four databases (Ovid Medline, Ovid Embase, Cochrane, Scopus) was undertaken. Inclusion and exclusion criteria were pre-determined and two reviewers independently screened the articles with disagreements arbitrated by a third reviewer. The primary outcome variable was 28-day mortality. Quality of studies were assessed using the Cochrane-risk-of-bias (RoB 2) tool. Of the 2919 studies yielded by the search strategy, 1274 duplicates were removed and 1645 screened on title and abstract. After the full text of 33 studies were assessed, two articles were included. Both studies were over 30 years old with small numbers of participants and with primary outcomes not including mortality. Of the data available, no statistically significant difference in mortality was detected. Hospital length of stay, reversal of shock or adverse events were not reported. Both studies were at risk of bias. There are no high quality or recent studies in the English literature investigating the use of steroids for haemorrhagic shocked trauma patients. PROSPERO: CRD42021239656.

Multi-disciplinary, simulation-based, standardised trauma team training within the Victorian State Trauma System. Emerg Med Australas 2023; 35:62-68. [PMID: 36052421 PMCID: PMC10087482 DOI: 10.1111/1742-6723.14068] [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: 09/02/2021] [Revised: 04/26/2022] [Accepted: 07/24/2022] [Indexed: 01/19/2023]
Abstract
OBJECTIVE Inconsistency in the structure and function of team-based major trauma reception and resuscitation is common. A standardised trauma team training programme was initiated to improve quality and consistency among trauma teams across a large, mature trauma system. The aim of this manuscript is to outline the programme and report on the initial perception of participants. METHODS The Alfred Trauma Team Reception and Resuscitation Training (TTRRT) programme commenced in March 2019. Participants included critical care and surgical craft group members commonly involved in trauma teams. Training was site-specific and included rural, urban and tertiary referral centres. The programme consisted of prescribed pre-learning, didactic lectures, skill stations and simulated team-based scenarios. Participant perceptions of the programme were collected before and after the programme for analysis. RESULTS The TTRRT was delivered to 252 participants and 120 responses were received. Significant improvement in participant-reported confidence was identified across all key topic areas. There was also a significant increase in both confidence and clinical exposure to trauma team leadership roles after participation in the programme (from 53 [44.2%] to 74 [61.7%; P = 0.007]). This finding was independent of clinician experience. CONCLUSIONS A team-based trauma reception and resuscitation education programme, introduced in a large, mature trauma system led to positive participant-reported outcomes in clinical confidence and real-life team leadership participation. Wider implementation combined with longitudinal data collection will facilitate correlation with patient and staff-centred outcomes.

Abstract
BACKGROUND Traumatic brain injury (TBI) is the largest contributor to death and disability in people who have experienced physical trauma. There are no national data on outcomes for people with moderate to severe TBI in Australia. OBJECTIVES To determine the incidence and key determinants of outcomes for patients with moderate to severe TBI, both for Australia and for selected population subgroups, including Aboriginal and Torres Strait Islander Australians. METHODS AND ANALYSIS The Australian Traumatic Brain Injury National Data (ATBIND) project will analyse Australia New Zealand Trauma Registry (ATR) data and National Coronial Information Service (NCIS) deaths data. The ATR documents the demographic characteristics, injury event description and severity, processes of care, and outcomes for people with major injury, including TBI, assessed and managed at the 27 major trauma services in Australia. We will include data for people with moderate to severe TBI (Abbreviated Injury Scale [AIS] (head) score higher than 2) who had Injury Severity Scores [ISS] higher than 12 or who died in hospital. People will also be included if they died before reaching a major trauma service and the coronial report details were consistent with moderate to severe TBI. The primary research outcome will be survival to discharge. Secondary outcomes will be hospital discharge destination, hospital length of stay, ventilator-free days, and health service cost. ETHICS APPROVAL The Alfred Ethics Committee approved ATR data extraction (project reference number 670/21). Further ethics approval has been sought from the NCIS and multiple Aboriginal health research ethics committees. The ATBIND project will conform with Indigenous data sovereignty principles. DISSEMINATION OF RESULTS Our findings will be disseminated by project partners with the aim of informing improvements in equitable system-level care for all people in Australia with moderate to severe TBI.

Reliability, Validity, Clinical Utility, and Responsiveness of Measures for Assessing Mobility and Physical Function in Patients With Traumatic Injury in the Acute Care Hospital Setting: A Prospective Study. Phys Ther 2021; 101:6330027.

Abstract
OBJECTIVE The longer-term impact of injury is increasingly recognized, but the early phases of recovery are less well understood. The best tools to measure early recovery of mobility and physical function following traumatic injury are unclear. The purpose of this study was to assess the clinical utility, validity, reliability, and responsiveness of 4 mobility and physical function measures in patients following traumatic injury. METHODS In this cohort, measurement-focused study (n = 100), the modified Iowa Level of Assistance Score, Acute Care Index of Function, Activity Measure for Post-Acute Care "6 Clicks" short forms, and Functional Independence Measure were completed during first and last physical therapy sessions. Clinical utility and floor and ceiling effects were documented. Known-groups validity (early vs late in admission and by discharge destination), predictive validity (using 6-month postinjury outcomes data), and responsiveness were established. Interrater reliability was assessed in 30 patients with stable mobility and function. RESULTS Participants had a median age of 52 years (interquartile range = 33-68 years), and 68% were male. The modified Iowa Level of Assistance Score, Acute Care Index of Function, and "6 Clicks" short forms were quick to administer (an extra median time of 30 seconds-1 minute), but the Functional Independence Measure took much longer (extra median time of 5 minutes). At the last physical therapy session, ceiling effects were present for all measures except the Functional Independence Measure (18%-33% of participants). All had strong known-groups validity (early vs late in admission and by discharge destination). All were responsive (effect sizes >1.0) and had excellent interrater reliability (intraclass correlation coefficients = 0.79-0.94). CONCLUSION All 4 measures were reliable, valid, and responsive; however, their clinical utility varied, and ceiling effects were common at physical therapy discharge. IMPACT This study is an important step toward evidence-based measurement in acute trauma physical therapy care. It provides critical information to guide assessment of mobility and physical function in acute trauma physical therapy, which may facilitate benchmarking across different hospitals and trauma centers and further progress the science and practice of physical therapy following traumatic injury.

Abstract
INTRODUCTION Injury is a major global health burden. Trauma registries have been used for decades to monitor the burden of injury and inform trauma care. However, the extent to which trauma registries have fulfilled their potential remains uncertain. The aims of this study were to determine the current and priority uses of trauma registries across Australia and New Zealand and to establish the priority clinical outcomes, the probability for which, if known for an individual trauma patient, would better inform that same patient's care, during hospital admission. METHODS A prospective observational study using survey methodology was conducted. Participants were sourced from the Australia New Zealand Trauma Registry (ATR) participating hospitals. The survey questions included: the current uses and priorities for both single-site trauma registries and the binational trauma registry; the five top-ranked priority outcomes for which knowing the probability, for an individual patient, would inform care; and the priority timepoints for applying patient-level outcome prediction models. RESULTS Of the 26 ATR-participating hospitals, 25 were represented by a total of 54 participants in the survey, including trauma service directors and trauma nurse coordinators. The main trauma registry use and priority for the single site registries was to inform the quality improvement program; for the ATR, the main use was periodic reporting and the main priority was benchmarking. For each potential purpose of the registry, the future priority level was ranked more highly than the current level of utilisation. The most highly ranked priority patient-level outcomes requiring prediction were: preventable death, missed injury, quality of life, admission costs, pulmonary embolism, post-traumatic stress disorder, length of hospital stay, errors in decision-making and deep venous thrombosis. The time period between leaving the emergency department and the 24 h mark following presentation was considered the preferred time for patient-level priority outcome prediction. CONCLUSION There is a mismatch between current trauma registry uses and future priorities. The priority outcomes demanding prediction in the first 24 h of a trauma patient's stay are preventable death, missed injury, quality of life, hospital costs, thromboembolism, post-traumatic stress disorder, length of hospital stay and errors in clinical decision-making.

Abstract
Moderate to severe traumatic brain injury (TBI) contributes to a significant burden across Australia. However, the data required to inform targeted equitable system-level improvements in emergency TBI care do not exist. The incidence and determinants of outcomes following moderate to severe TBI in Australia remain unknown. The variation in the impact of moderate to severe TBI, according to patient demographics and injury mechanism, is poorly defined. The Australian Traumatic Brain Injury National Data Project will lead to a clear understanding, across Australia and pre-specified subgroups (including Aboriginal and Torres Strait Islander peoples), of the incidence, determinants and impact of priority outcomes following moderate to severe TBI, including survival to discharge home. Furthermore, this project will establish a set of national clinical quality indicators for patients experiencing a moderate to severe TBI. The Australian Traumatic Brain Injury National Data Project will inform where to target emergency care system-wide improvements. Without baseline data, efforts are wasted.

Abstract
AbstractInjury from motor vehicle accidents remains a leading cause of death in India with increasing number of fatalities. Timely delivery of lifesaving interventions is critical for survival and in restoring physical functioning. As a part of the Australia India Trauma Systems Collaboration, the Trauma Reception and Resuscitation (TRR©)-computerized decision support system was implemented in a Level 1 Trauma Centre in India in order to determine whether this system would reduce the time in performing lifesaving interventions and improve vital sign data capture and documentation. This prospective cohort study at the Jai Prakash Narayan Apex Center, All India Institute of Medical Science, New Delhi, recruited a total of 106 participants into two groups: TRR© (76) and controls (30). During the first 30 min of resuscitation, the TRR© group recorded greater sets of vital signs in compared to the controls for medical records. More importantly, the real-time documentation of the vital signs for the TRR© group ensured accuracy for medical records. For lifesaving interventions, oxygen was administered in the TRR© group only if SpO2 < 93%, whereas oxygen was administered as standard of care in the controls. There was no statistical difference in the mean times to endotracheal intubation, intercostal catheter insertion or performance of emergency chest x-ray between the control and TRR© groups. Importantly however, these 3 comparable interventions were performed consistently within a smaller timeframe for patients receiving care with TRR© decision prompts. There was a greater variability in the time taken to perform lifesaving interventions in the control group in comparison to the clinicians assisted with computerized decision prompts. This preliminary study was not powered to measure difference in mortality and patient recruitment was limited to 8 am–5 pm when trained staff could attend to operating the TRR© system.

Abstract
Introduction: Delayed Intracranial Hemorrhage (D-ICH), defined as finding of ICH on subsequent imaging after a normal computed tomography of the brain (CTB), is a feared complication after head trauma. The aim of this study was to determine the incidence and severity of D-ICH.Methods: This retrospective cohort study included patients that presented directly from the scene of injury to an adult major trauma center from Jan 2013 to Dec 2018.Results: There were 6536 patients who had an initial normal CTB and 23 (0.3%; 95%CI: 0.20-0.47) had D-ICH. There were 653 patients who had a repeat CTB (incidence of D-ICH 3.5%; 95%CI: 2.2-5.2). There was no significant association of D-ICH with age>65 years (OR 1.33; 95%CI: 0.54-3.29), presenting GCS <15 (OR 1.21; 95% CI: 0.52-2.80) and anti-platelet medications (OR 0.68; 95%CI: 0.26-1.74). Exposure to anti-coagulant medications was associated with lower odds of D-ICH (OR 0.23; 95%CI: 0.05-0.99). All cases of D-ICH were diffuse injury type II lesions on the Marshall classification. There were no cases that underwent neurosurgical intervention and no deaths were attributed to D-ICH.Conclusions: These results question observation of patients with head injury in hospital after a normal CTB for the sole purpose of excluding D-ICH.

Splenic Artery Embolization after Delayed Splenic Rupture Following Blunt Trauma: Is Nonoperative Management Still an Option in This Cohort? J Vasc Interv Radiol 2021; 32:586-592. [PMID: 33551305 DOI: 10.1016/j.jvir.2020.10.011] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2020] [Revised: 10/09/2020] [Accepted: 10/12/2020] [Indexed: 10/22/2022] Open
Abstract
Patients treated with splenic artery embolization (SAE) >48 hours after a blunt injury for a delayed splenic rupture (DSR) were assessed for the need for a subsequent splenectomy. Thirty-four patients underwent SAE for DSR over 10 years at our level 1 trauma center, performed at a median of 4.5 days after the injury (interquartile range = 5.5), and the patients were followed up for a median of 11 months (interquartile range = 31). There were 3 occurrences of rebleeds, and 2 patients required splenectomy (5.9%). This study showed that treatment with SAE after DSR results in splenic salvage in 94.1% of patients.

Hypocalcemia in trauma patients: A systematic review. J Trauma Acute Care Surg 2021; 90:396-402. [PMID: 33196630 PMCID: PMC7850586 DOI: 10.1097/ta.0000000000003027] [Citation(s) in RCA: 31] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2020] [Revised: 10/22/2020] [Accepted: 10/31/2020] [Indexed: 01/11/2023]
Abstract
BACKGROUND During hemorrhagic shock and subsequent resuscitation, pathways reliant upon calcium such as platelet function, intrinsic and extrinsic hemostasis, and cardiac contractility are disrupted. The objective of this systematic review was to examine current literature for associations between pretransfusion, admission ionized hypocalcemia, and composite outcomes including mortality, blood transfusion requirements, and coagulopathy in adult trauma patients. METHODS This review was reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. We searched Ovid MEDLINE and grey literature from database inception till May 3, 2020. Case series and reports were excluded. Reference lists of appraised studies were also screened for articles that the aforementioned databases might not have captured. The Newcastle-Ottawa Scale was used to assess study quality. RESULTS A total of 585 abstracts were screened through database searching and alternative sources. Six unique full-text studies were reviewed, of which three were excluded. Admission ionized hypocalcemia was present in up to 56.2% of the population in studies included in this review. Admission ionized hypocalcemia was also associated with increased mortality in all three studies, with increased blood transfusion requirements in two studies, and with coagulopathy in one study. CONCLUSION Hypocalcemia is a common finding in shocked trauma patients. While an association between admission ionized hypocalcemia and mortality, blood transfusion requirements, and coagulopathy has been identified, further prospective trials are essential to corroborating this association. LEVEL OF EVIDENCE Systematic review, level III.

Impact of In-hospital and Outreach models for regional P.A.R.T.Y. Program participants. Emerg Med Australas 2020; 33:640-646. [PMID: 33340262 DOI: 10.1111/1742-6723.13693] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2020] [Revised: 11/09/2020] [Accepted: 11/12/2020] [Indexed: 11/29/2022]
Abstract
OBJECTIVE This retrospective observational study aimed to compare the impact of the Prevent Alcohol and Risk-Related Trauma Youth (P.A.R.T.Y.) Program when delivered as In-hospital or Outreach models to rural and regional students. METHODS The study population were consented participants from regional areas between 2013 and 2017 who completed pre-programme, immediately post-programme and 3-5 months post-programme surveys. Responses from the metropolitan In-hospital programme participants and regional Outreach programme participants were analysed within groups across the three time points. The primary outcome variable was a change in self-reported perception of driving after drinking alcohol. Secondary outcome variables were designating a safe driver after drinking, perception of risk of injury if not wearing a seatbelt, risks of injury if undertaking physical risk-taking activities and likelihood of the programme changing perceptions. RESULTS There were 1314 participants invited to participate and 547 (42%) sets of complete surveys were received, of whom 296 (54%) were Outreach participants. Pre-programme, a significantly lower proportion of Outreach participants reported 'definitely not' to driving after drinking (84% vs 91%), and perceived a 'definite' likelihood of sustaining injury if not wearing a seatbelt (57% vs 66%). Outreach participants displayed improvements in likelihood to drive after drinking alcohol immediately post-programme and on follow up (P = 0.028). Responses to all other secondary outcome measures demonstrated some improvement. CONCLUSIONS Although demographically similar, baseline perceptions toward alcohol, risk-taking and injury differed between groups. Improvements in perception were demonstrated across both models. These findings support P.A.R.T.Y. as an injury prevention initiative for regional youth.

Penetrating angle grinder injury to the neck causing subclavian artery injury. Trauma Case Rep 2020; 31:100378. [PMID: 33364292 PMCID: PMC7750567 DOI: 10.1016/j.tcr.2020.100378] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 12/06/2020] [Indexed: 11/03/2022] Open
Abstract
Penetrating injuries to the neck present a unique challenge due to the confined space of the thoracic outlet for haemorrhage control and repair. This results in high mortality rates when the major vascular structures of the neck are transected, as well as potential neurological compromise. We present the case of a penetrating injury to the proximal subclavian artery from a broken angle grinder disc which is a unique mechanism of injury that can have fatal consequences. The patient described in this case underwent an emergent median sternotomy for proximal control of the brachiocephalic trunk and ligation of the right vertebral artery to facilitate a primary repair of the injured vessel segment. Post operatively the patient made a complete recovery with no central or peripheral neurologic deficits and requiring no further interventions. The key points from this case are that angle grinders pose a significant injury burden and early specialised medical attention should be sought, rapid control of the proximal neck vessels can be obtained via a median sternotomy and that the vertebral artery can be ligated in an emergent situation without neurological consequence.

Abstract
Objective Procedural complication rates associated with tube thoracostomy for pleural decompression is estimated to be between 2 and 25%, with incorrect insertion site being a common problem. We hypothesised that the inferior-most hair follicle in the axillary region would provide an accurate biometric marker to identify the fourth to sixth intercostal space. Methods A prospective cohort of patients requiring computed tomography scan of the chest was recruited from February 2015 to March 2016 at The Alfred Hospital. The inferior-most hair follicle on the patient’s axillary region was tagged with a paperclip, and a radiologist reported this location with reference to the corresponding intercostal spaces. Results Of the 254 enrolled patients, a total of 310 paperclip positions over intercostal spaces were analysed. There were 101 (32.5%) paperclips positioned in the fourth and fifth intercostal spaces with the remainder at the second or third intercostal spaces, and no paperclips placed at the sixth intercostal space or lower. Conclusions This study demonstrated that the inferior-most hair follicle in the axilla corresponded to an area between the second and fifth intercostal spaces. Recognition of this surface anatomy has the potential to eliminate iatrogenic injuries to the diaphragm and sub-diaphragmatic organs, but should not be used as the sole marker due to potential risks from high placement of pleural drains.

In adult patients with severe traumatic brain injury, does the use of norepinephrine for augmenting cerebral perfusion pressure improve neurological outcome? A systematic review. Injury 2020; 51:2129-2134. [PMID: 32739152 DOI: 10.1016/j.injury.2020.07.054] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/30/2020] [Revised: 07/24/2020] [Accepted: 07/24/2020] [Indexed: 02/02/2023]
Abstract
BACKGROUND AND OBJECTIVE Despite multiple interventions, mortality due to severe traumatic brain injury (sTBI) within mature Trauma Systems has remained unchanged over the last decade. During this time, the use of vasoactive infusions (commonly norepinephrine) to achieve a target blood pressure and cerebral perfusion pressure (CPP) has been a mainstay of sTBI management. However, evidence suggests that norepinephrine, whilst raising blood pressure, may reduce cerebral oxygenation. This study aimed to review the available evidence that links norepinephrine augmented CPP to clinical outcomes for these patients. METHODS A systematic review examining the evidence for norepinephrine augmented CPP in TBI patients was undertaken. Strict inclusion and exclusion criteria were developed for a dedicated literature search of multiple scientific databases. Two dedicated reviewers screened articles, whilst a third dedicated reviewer resolved conflicts. RESULTS The systematic review yielded 4,809 articles, of which 1,197 duplicate articles were removed. After abstract/title screening, 45 articles underwent full text review, resulting in the identification of two articles that investigated the effect of norepinephrine administration on clinical outcomes in patients following TBI when compared to other vasopressors. Neither study found a difference in neurological outcome between the vasopressor groups. No articles measured the effect of norepinephrine compared to no vasopressor use on the clinical outcome of patients with sTBI. CONCLUSIONS Despite being a mainstay of pharmacological management for hypotension in patients following sTBI, there is minimal clinical evidence supporting the use of norepinephrine in targeting a CPP for either improving neurological outcomes or reducing mortality. Outcomes-based clinical trials exploring the role of brain tissue perfusion and oxygenation monitoring are required to validate any benefit.

Abstract
OBJECTIVES To assess the effect of a mobile phone application for prehospital notification on resuscitation and patient outcomes. DESIGN Longitudinal prospective cohort study with preintervention and postintervention cohorts. SETTING Major trauma centre in India. PARTICIPANTS Injured patients being transported by ambulance and allocated to red (highest) and yellow (medium) triage categories. INTERVENTION A prehospital notification application for use by ambulance and emergency clinicians to notify emergency departments (EDs) of an impending arrival of a patient requiring advanced lifesaving care. MAIN OUTCOME MEASURES The primary outcome was the proportion of eligible patients arriving at the hospital for which prehospital notification occurred. Secondary outcomes were the availability of a trauma cubicle, presence of a trauma team on patient arrival, time to first chest X-ray, and ED and in-hospital mortality. RESULTS Data from January 2017 to January 2018 were collected with 208 patients in the preintervention and 263 patients in the postintervention period. The proportion of patients arriving after prehospital notification improved from 0% to 11% (p<0.001). After the intervention, more patients were managed with a trauma call-out (relative risk (RR) 1.30; 95% CI: 1.10 to 1.52); a trauma bay was ready for more patients (RR 1.47; 95% CI: 1.05 to 2.05) and a trauma team leader present for more patients (RR 1.50; 95% CI: 1.07 to 2.10). There was no difference in time to the initial chest X-ray (p=0.45). There was no association with mortality at hospital discharge (RR 0.94; 95% CI: 0.72 to 1.23), but the intervention was associated with significantly less risk of patients dying in the ED (RR 0.11; 95% CI: 0.03 to 0.39). CONCLUSIONS The prehospital notification application for severely injured patients had limited uptake but implementation was associated with improved trauma reception and reduction in early deaths. Quality improvement efforts with ongoing data collection using the trauma registry are indicated to drive improvements in trauma outcomes in India. TRIAL REGISTRATION NUMBER NCT02877342.

Emergency department resuscitative thoracotomy at an adult major trauma centre: Outcomes following a training programme with standardised indications. Emerg Med Australas 2020; 32:657-662. [PMID: 32400039 DOI: 10.1111/1742-6723.13530] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2019] [Revised: 10/16/2019] [Accepted: 10/27/2019] [Indexed: 11/28/2022]
Abstract
OBJECTIVE The objective of this study was to report the procedural incidence and patient outcomes after the 2009 introduction of an institutional resuscitative thoracotomy (RT) programme. Emergency physicians, general surgeons and emergency nursing trauma team members were trained to perform RT on thoracic trauma patients with an unresponsive systolic blood pressure (SBP) <70 mmHg within 30 min of arrival, prior to cardiothoracic team back-up. METHODS A retrospective cohort study was conducted on patients who underwent RT from 2009 to 2017. The primary outcome measures were the incidence of the procedure and patients' survival to hospital discharge. Variables associated with survival were assessed using univariable logistic regression analyses. RESULTS There were 12 399 major trauma patients, including 7657 with major thoracic trauma and 315 presenting with SBP <70 mmHg. There were 32 RTs performed (incidence of 0.4%; 95% confidence interval [CI] 0.3-0.6) among patients with major thoracic trauma and 10.2% (99% CI 7.3-13.4) among patients with major thoracic trauma and SBP <70 mmHg. There were eight (25%; 95% CI 13.2-42.1) survivors to hospital discharge and no late mortality (mean follow-up 2.8 years). Survival was significantly associated with the procedure performed within 30 min of arrival (odds ratio 0.09; 95% CI 0.01-0.67) while mortality was associated with the procedure being performed in the setting of traumatic cardiac arrest (odds ratio 18.3; 95% CI 2.4-140.4). CONCLUSIONS A formal training and credentialing programme was associated with a low incidence of the procedure, yet achieved a survival rate of 25%, which is comparable to other reported literature.

Abstract
OBJECTIVE To investigate trends in the incidence and causes of traumatic spinal cord injury (TSCI) in Victoria over a 10-year period. DESIGN, SETTING, PARTICIPANTS Retrospective cohort study: analysis of Victorian State Trauma Registry (VSTR) data for people who sustained TSCIs during 2007-2016. MAIN OUTCOMES AND MEASURES Temporal trends in population-based incidence rates of TSCI (injury to the spinal cord with an Abbreviated Injury Scale [AIS] score of 4 or more). RESULTS There were 706 cases of TSCI, most the result of transport events (269 cases, 38%) or low falls (197 cases, 28%). The overall crude incidence of TSCI was 1.26 cases per 100 000 population (95% CI, 1.17-1.36 per 100 000 population), and did not change over the study period (incidence rate ratio [IRR], 1.01; 95% CI, 0.99-1.04). However, the incidence of TSCI resulting from low falls increased by 9% per year (95% CI, 4-15%). The proportion of TSCI cases classified as incomplete tetraplegia increased from 41% in 2007 to 55% in 2016 (P < 0.001). Overall in-hospital mortality was 15% (104 deaths), and was highest among people aged 65 years or more (31%, 70 deaths). CONCLUSIONS Given the devastating consequences of TSCI, improved primary prevention strategies are needed, particularly as the incidence of TSCI did not decline over the study period. The epidemiologic profile of TSCI has shifted, with an increasing number of TSCI events in older adults. This change has implications for prevention, acute and post-discharge care, and support.

Abstract
Background Trauma registries are essential to trauma systems, to enable collection of the data needed to enhance clinical knowledge and monitor system performance. The King Saud Medical City (KSMC) in Riyadh, Kingdom of Saudi Arabia (KSA) is aiming to become a Level 1 Trauma Centre, and required a trauma registry in order to do so. Our objective was to establish the Saudi TraumA Registry (STAR) at the (KSMC) and ready it for national deployment. The challenge was that no formal trauma data collection had occurred previously and clinicians had no prior experience of trauma registries. Methods To develop the registry, a novel 12 step implementation plan was created and followed at the KSMC. Registry criteria and a Minimum Dataset were selected; training was delivered; database specifications were written; operating procedures were developed and regular reporting was initiated. Results Data collection commenced on August 1st 2017. The registry was fully operational by April 2018, eight months ahead of schedule. During the first year of data collection an average of 216 records per month were entered into the database. An inaugural report was presented at the Saudi Trauma Conference in February 2019. Conclusions The strategy deployed at the KSMC has successfully established the STAR. In the short term, process indicators will track the development of the hospital into a Level 1 Trauma Centre. In the medium to long term the STAR will be rolled out nationally to capture the impact of public health initiatives aimed at reducing injury in the KSA. The effect of the STAR will be that the country is better equipped to deliver continuous improvements in trauma systems and quality of care.

Abstract
BACKGROUND The completeness of a trauma registry's data is essential for its valid use. This study aimed to evaluate the extent of missing data in a new multicentre trauma registry in India and to assess the association between data completeness and potential predictors of missing data, particularly mortality. METHODS The proportion of missing data for variables among all adults was determined from data collected from 19 April 2016 to 30 April 2017. In-hospital physiological data were defined as missing if any of initial systolic blood pressure, heart rate, respiratory rate, or Glasgow Coma Scale were missing. Univariable logistic regression and multivariable logistic regression, using manual stepwise selection, were used to investigate the association between mortality (and other potential predictors) and missing physiological data. RESULTS Data on the 4466 trauma patients in the registry were analysed. Out of 59 variables, most (n = 51; 86.4%) were missing less than 20% of observations. There were 808 (18.1%) patients missing at least one of the first in-hospital physiological observations. Hospital death was associated with missing in-hospital physiological data (adjusted OR 1.4; 95% CI 1.02-2.01; p = 0.04). Other significant associations with missing data were: patient arrival time out of hours, hospital of care, 'other' place of injury, and specific injury mechanisms. Assault/homicide injury intent and occurrence of chest X-ray were associated with not missing any of first in-hospital physiological variables. CONCLUSION Most variables were well collected. Hospital death, a proxy for more severe injury, was associated with missing first in-hospital physiological observations. This remains an important limitation for trauma registries.

Abstract
BACKGROUND Each year approximately five million people die from injuries. In countries where systems of trauma care have been introduced, death and disability have decreased. A major component of developed trauma systems is a trauma quality improvement (TQI) program and trauma quality improvement meeting (TQIM). Effective TQIMs improve trauma care by identifying and fixing problems. But globally, TQIMs are absent or unstructured in most hospitals providing trauma care. The aim of this study was to implement and evaluate a checklist for a structured TQIM. METHODS This project was conducted as a prospective before-and-after study in four major trauma centres in India. The intervention was the introduction of a structured TQIM using a checklist, introduced with a workshop. This workshop was based on the World Health Organization (WHO) TQI Programs short course and resources, plus the developed TQIM checklist. Pre- and post-intervention data collection occurred at all meetings in which cases of trauma death were discussed. The primary outcome was TQIM Checklist compliance, defined by the discussion of, and agreement upon each of the following: preventability of death, identification of opportunities to improve care and corrective actions and a plan for closing the loop. RESULTS There were 34 meetings in each phase, with 99 cases brought to the pre-intervention phase and 125 cases brought to the post-intervention phase. There was an increase in the proportion of cases brought to the meeting for which preventability of death was discussed (from 94% to 100%, p = 0.007) and agreed (from 7 to 19%, OR 3.7; 95% CI:1.4-9.4, p = 0.004) and for which a plan for closing the loop was discussed (from 2% to 18%, OR 10.9; 95% CI:2.5-47.6, p < 0.001) and agreed (from 2% to 18%, OR 10.9; 95% CI:2.5-47.6, p < 0.001). CONCLUSION This study developed, implemented and evaluated a TQIM Checklist for improving TQIM processes. The introduction of a TQIM Checklist, with training, into four Indian trauma centres, led to more structured TQIMs, including increased discussion and agreement on preventability of death and plans for loop closure. A TQIM Checklist should be considered for all centres managing trauma patients.

Timely completion of multiple life-saving interventions for traumatic haemorrhagic shock: a retrospective cohort study. BURNS & TRAUMA 2019; 7:22. [PMID: 31360731 PMCID: PMC6637602 DOI: 10.1186/s41038-019-0160-5] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/08/2019] [Accepted: 05/07/2019] [Indexed: 11/10/2022]
Abstract
Background Early control of haemorrhage and optimisation of physiology are guiding principles of resuscitation after injury. Improved outcomes have been previously associated with single, timely interventions. The aim of this study was to assess the association between multiple timely life-saving interventions (LSIs) and outcomes of traumatic haemorrhagic shock patients. Methods A retrospective cohort study was undertaken of injured patients with haemorrhagic shock who presented to Alfered Emergency & Trauma Centre between July 01, 2010 and July 31, 2014. LSIs studied included chest decompression, control of external haemorrhage, pelvic binder application, transfusion of red cells and coagulation products and surgical control of bleeding through angio-embolisation or operative intervention. The primary exposure variable was timely initiation of ≥ 50% of the indicated interventions. The association between the primary exposure variable and outcome of death at hospital discharge was adjusted for potential confounders using multivariable logistic regression analysis. The association between total pre-hospital times and pre-hospital care times (time from ambulance at scene to trauma centre), in-hospital mortality and timely initiation of ≥ 50% of the indicated interventions were assessed. Results Of the 168 patients, 54 (32.1%) patients had ≥ 50% of indicated LSI completed within the specified time period. Timely delivery of LSI was independently associated with improved survival to hospital discharge (adjusted odds ratio (OR) for in-hospital death 0.17; 95% confidence interval (CI) 0.03–0.83; p = 0.028). This association was independent of patient age, pre-hospital care time, injury severity score, initial serum lactate levels and coagulopathy. Among patients with pre-hospital time of ≥ 2 h, 2 (3.6%) received timely LSIs. Pre-hospital care times of ≥ 2 h were associated with delayed LSIs and with in-hospital death (unadjusted OR 4.3; 95% CI 1.4–13.0). Conclusions Timely completion of LSI when indicated was completed in a small proportion of patients and reflects previous research demonstrating delayed processes and errors even in advanced trauma systems. Timely delivery of a high proportion of LSIs was associated with improved outcomes among patients presenting with haemorrhagic shock after injury. Provision of LSIs in the pre-hospital phase of trauma care has the potential to improve outcomes.

[PMID: 31083786 DOI: 10.1111/ans.15253] [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: 02/07/2019] [Revised: 03/21/2019] [Accepted: 03/27/2019] [Indexed: 11/28/2022]
Abstract
BACKGROUND In patients who are awake with normal mental and neurologic status, it has been suggested that the thoracolumbar (TL) spine may be cleared by clinical examination, irrespective of the mechanism of injury. The aim of this pilot study was to test the feasibility and accuracy of a clinical decision tool focused towards clearance of the TL spine during assessment of patients in the emergency department after trauma. METHODS A prospective interventional study was conducted at two major trauma centres. The intervention of a clinical decision tool for assessment of the TL spine was applied prospectively to all patients with subsequent imaging results acting as the comparator. The primary outcome variable was fracture of the thoracic or lumbar vertebra(e). The clinical decision tool was assessed using sensitivity and specificity for detecting a TL fracture and reported with 95% confidence intervals (CIs). RESULTS There were 188 cases included for analysis that all underwent imaging of the thoracic and/or lumbar vertebrae. There were 34 (18%) patients diagnosed with fractures of the thoracic and/or lumbar vertebrae. In this pilot study, sensitivity of the clinical decision tool was 100% (95% CI 87.3-100%) and specificity was 37.0% (95% CI 29.5-45.2%) for the detection of a thoracic or lumbar vertebral fracture. CONCLUSIONS Feasibility of clinical clearance of the TL spine in two major trauma centres was demonstrated in a clinical study setting. Evaluation of this clinical decision tool in patients following blunt trauma, particularly in reducing imaging rates, is indicated using a larger prospective study.

Abstract
Introduction Injuries are a major cause of disability and lost productivity. The case for a national trauma registry has been recognized by the Australian Commission on Safety and Quality in Health Care and at a policy level. Background The need was flagged in 1993 by the Royal Australasian College of Surgeons and the Australasian Trauma Society. In 2003, the Centre of National Research and Disability funded the Australian and New Zealand National Trauma Registry Consortium, which produced three consecutive annual reports. The bi‐national trauma minimum dataset was also developed during this time. Operations were suspended thereafter. Method In response to sustained lobbying the Australian Trauma Quality Improvement Program including the Australian Trauma Registry (ATR) commenced in 2012, with data collection from 26 major trauma centres. An inaugural report was released in late 2014. Result The Federal Government provided funding in December 2016 enabling the work of the ATR to continue. Data are currently being collected for cases that meet inclusion criteria with dates of injury in the 2017–2018 financial year. Since implementation, the number of submitted records has been increased from fewer than 7000 per year to over 8000 as completeness has improved. Four reports have been released and are available to stakeholders. Conclusion The commitment shown by the College, other organizations and individuals to the vision of a national trauma registry has been consistent since 1993. The ATR is now well placed to improve the care of injured people.

Abstract
Acute subdural hematoma (aSDH) is among the most common injury types encountered by neurosurgeons, and carries a poor prognosis, particularly in the elderly. As the incidence of aSDH in the elderly population rises, identifying those patients who may benefit from operative intervention is crucial. This systematic review aimed to identify data on prognostic factors or indices, such as the modified frailty index, that may help predict outcome, and hence guide management. A comprehensive search of online databases was conducted by two independent authors, and data on prognostic factors and outcomes were extracted. The quality of the evidence was evaluated using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria. Of 769 studies identified in the initial search, 7 satisfied inclusion and exclusion criteria. Mortality and morbidity varied considerably among studies. Initial Glasgow Coma Scale (GCS) of 3-8 was the most consistently reported negative prognostic feature. Several studies evaluated the impact of medical comorbidities and premorbid frailty, but were limited by small sample size. A previous history of pneumonia was shown to increase the risk of Glasgow Outcome Score (GOS) 1-3 (odds ratio [OR] 6.4 [95% CI 1.6-25.2], p = 0.04) in a single study, which also reported a greater increase in GOS at 3 months in those with fewer than five comorbidities (56% vs. 19%, p < 0.01). There are limited data describing prognostic factors or the use of frailty indices within the specific group of elderly patients with aSDH. Prospective research is needed to evaluate the utility of accurate and validated assessments of frailty to enhance the neurosurgeon's ability to appropriately manage this complex and expanding patient group.

Abstract
Introduction Traumatic aortic injury is an uncommon condition. Timely diagnosis may enable early haemostatic resuscitation, essential to prevent worsening of the injury prior to definitive management. The aim of this study was to assess the utility of initial vital signs and presenting clinical characteristics to confirm or rule out aortic injury. Methods A retrospective review of patients from The Alfred Trauma Registry was conducted. Patients presenting between January 2006 and July 2014 and diagnosed with aortic injury were identified. Demographics and presenting clinical characteristics were extracted. Sensitivity of individual clinical variables for the detection of aortic injury was calculated. Results There were 77 patients identified with aortic injury, with an in-hospital mortality rate of 19.5% (95% CI: 10.6–28.3%). Of these, 68 (88.3%) patients presented after high-energy blunt mechanisms. Clinical signs and early chest X-ray findings were poorly sensitive to detect aortic injury. Patients who presented with hypotension had a greater severity of aortic injury, more commonly had associated abnormal investigation findings and were more likely to require blood products and inotropic agents (p < 0.05). However, sensitivity of initial hypotension to rule out aortic injury was 39.0% (95% CI: 28.1–49.9%). Conclusions The diagnosis of aortic injury was uncommon in hospital. Most injuries were secondary to high-velocity road traffic crashes or high falls. Clinical signs were not adequately sensitive to be used for the exclusion of aortic injury. We recommend a high degree of clinical suspicion and liberal imaging among cases where aortic injury is possible.

Preparedness for treating victims of terrorist attacks in Australia: Learning from recent military experience. Emerg Med Australas 2018; 30:722-724. [PMID: 29740959 DOI: 10.1111/1742-6723.13091] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2018] [Accepted: 04/09/2018] [Indexed: 12/01/2022]
Abstract
The Australian health system is generally well prepared for mass casualty events. Fortunately, there have been very few terrorist attacks and these have involved low numbers of casualties compared with events overseas. Nevertheless, Australian health professionals need to be prepared to treat mass casualties with blast and ballistic trauma. The US military and its allies including Australia have had extensive experience with mass casualty management in the Middle East and Afghanistan wars for more than a decade. To define their experience, they developed the Tactical Combat Casualty Care Guidelines that have saved many lives. It is now prudent to incorporate this knowledge and experience into civilian practice in Australia.

Do patients with blunt thoracic aortic injury present to hospital with unstable vital signs? A systematic review and meta-analysis. Emerg Med J 2018; 35:231-237. [PMID: 29440235 DOI: 10.1136/emermed-2017-206688] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2017] [Revised: 01/12/2018] [Accepted: 01/19/2018] [Indexed: 11/03/2022]
Abstract
BACKGROUND Blunt thoracic aortic injury (BTAI) is an uncommon diagnosis, usually developing as a consequence of high-impact acceleration-deceleration mechanisms. Timely diagnosis may enable early resuscitation and reduction of shear forces, essential to prevent worsening of the injury prior to definitive management. Death is commonly due to haemorrhagic shock, but clinical features may be absent until sudden and massive haemorrhage. OBJECTIVES The aim of this systematic review was to determine the proportion of patients with BTAI who present with unstable vital signs. METHODS Manuscripts were identified through a search of MEDLINE, EMBASE and the Cochrane Library databases, focusing on subject headings and keywords related to the aorta and trauma. Mechanisms of injury, haemodynamic status and mortality from the included manuscripts were reviewed. Meta-analysis of presenting haemodynamic status among a select group of similar papers was conducted. RESULTS Nineteen studies were included, with five selected for meta-analysis. Most reported cases of BTAI (80.0%-100%) were caused by road traffic incidents, with mortality consistently higher among initially unstable patients. There was statistically significant heterogeneity among the included studies (P<0.01). The pooled proportion of patients with haemodynamic instability in the setting of BTAI was 48.8% (95% CI 8.3 to 89.4). CONCLUSIONS Normal vital signs do not rule out aortic injury. A high degree of clinical suspicion and liberal use of imaging is necessary to prevent missed or delayed diagnoses.

Variables associated with pulmonary thromboembolism in injured patients: A systematic review. Injury 2018; 49:1-7. [PMID: 28843717 DOI: 10.1016/j.injury.2017.08.024] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/02/2017] [Revised: 07/28/2017] [Accepted: 08/11/2017] [Indexed: 02/02/2023]
Abstract
BACKGROUND Pulmonary thromboembolism (PTE) is a dangerous complication of traumatic injury, with varied risk profiles and treatment options. This review aims to describe reported incidence and variables associated with PTE among severely injured patients. METHODS Searches were conducted using PubMed, Cochrane and MEDLINE. Relevant studies were identified by two independent reviewers based on predetermined inclusion criteria. Incidence of PTE was the primary outcome measure. Variables associated with PTE was the secondary outcome measure. The Newcastle-Ottawa Scale was used to assess quality of included studies. RESULTS There were eight studies that satisfied inclusion criteria. The diagnosed incidence of PTE in these populations ranged from 0.35 to 24%. The most common variables associated with PTE were pelvic or lower limb injury, chest injury, higher total Injury Severity Score, male sex and age. Variables that were less commonly associated with PTE were previous warfarin use, head injury, high serum lactate, soft tissue injury, more than one operation, more than three days on a ventilator, presence of a subclavian central venous catheter, need for a blood transfusion, systolic blood pressure <90mmHg, abdominal injury, presence of a deep venous thrombosis, inferior vena cava filter placement and isolated liver spleen or spinal injuries. CONCLUSIONS The reported incidence of PTE after major trauma is variable and dependent on inclusion criteria, diagnostic criteria and study design. Identified variables differed to those reported for venous thromboembolism in other populations. It is difficult to predict populations at risk of clinically significant PTE following injury using available evidence. Further studies linked to patient-specific variables will assist in more precise risk-stratification and interventions.

Abstract
BACKGROUND Computed tomography of the brain (CTB) has a fundamental role in the diagnosis and management of traumatic brain injury (TBI). There may be substantial discordance between initial CTB interpretation by emergency clinicians and the final radiology report. This study aimed to assess the utility of a structured reporting template in improving the accuracy of CTB interpretation by emergency clinicians. METHOD A prospective pre- and post-intervention cohort study was undertaken using a study population of emergency medicine trainees. The CTB reporting template was created with consultation from radiology, emergency medicine and trauma specialists. Participants reported on a set of randomly selected trauma CTBs first without, and then with, the reporting template. Each case was independently assessed for concordance with the radiology report by two blinded assessors (including a radiologist) and the proportion of concordant reports in each phase calculated. RESULTS There were 26 participants recruited to the study who reported on a total of 320 CTBs. In the pre-intervention phase, 121 (76%) cases were concordant with the radiology report compared to 147 (92%) post-intervention (p<0.01). The AUROC was 0.84 (95% CI: 0.78-0.89) pre-intervention and improved to 0.94 (95% CI: 0.88-0.99) with the intervention (p=0.01). A higher level of baseline accuracy was observed in advanced trainees (78%) compared to basic trainees (72%), but both improved to a similar level of 92% with the use of the CTB reporting template. There was a marked reduction in false negative errors, with increased identification of critical diagnoses such as cerebral herniation and diffuse axonal injury. CONCLUSION The use of the CTB reporting template significantly increased the accuracy of emergency medicine trainees and reduced the number of missed critical diagnoses. Reporting templates may represent an effective strategy to improve CTB interpretation and enhance the initial care of head injured patients.

Abstract
Background: Cardiac injury is uncommon, but it is important to diagnose, in order to prevent subsequent complications. Extended focused assessment with sonography in trauma (eFAST) allows rapid evaluation of the pericardium and thorax. The objective of this study was to describe cardiac injuries presenting to a major trauma centre and the diagnostic performance of eFAST in detecting haemopericardium as well as broader cardiac injuries. Methods: Data of patients with severe injuries and diagnosed cardiac injuries (Injury Severity Score >12 and AIS 2008 codes for cardiac injuries) were extracted from The Alfred Trauma Registry over a four-year period from July 2010 to June 2014. The initial eFAST results were compared to those of the final diagnosis, which were determined after analysing imaging results and intraoperative findings. Results: Thirty patients who were identified with cardiac injuries met the inclusion criteria. Among these, 22 patients sustained injuries under the scope of eFAST, of which a positive eFAST scan in the pericardium was reported in 13 (59%) patients, while nine (41%) patients had a negative scan. This resulted in a sensitivity of 59% (95% CI: 36.7%–78.5%). The sensitivity of detecting any cardiac injuries was lower at 43.3% (95% CI: 26.0–62.3). Conclusions: The low sensitivities of eFAST for detecting cardiac injuries and haemopericardium demonstrate that a negative result cannot be used in isolation to exclude cardiac injuries. A high index of suspicion for cardiac injury remains essential. Adjunct diagnostic modalities are indicated for the diagnosis of cardiac injury following major trauma.

Abstract
INTRODUCTION The aim of this study was to evaluate the incidence and severity of blunt cardiac injury (BCI) as determined by cardiac magnetic resonance imaging (CMR), and to compare this to currently used diagnostic methods in severely injured patients. MATERIALS AND METHODS We conducted a prospective, pilot cohort study of 42 major trauma patients from July 2013 to Jan 2015. The cohort underwent CMR within 7 days, enrolling 21 patients with evidence of chest injury and an elevated Troponin I compared to 21 patients without chest injury who acted as controls. Major adverse cardiac events (MACE) including ventricular arrhythmia, unexplained hypotension requiring inotropes, or a requirement for cardiac surgery were recorded. RESULTS 6/21 (28%) patients with chest injuries had abnormal CMR scans, while all 21 control patients had normal scans. CMR abnormalities included myocardial oedema, regional wall motion abnormalities, and myocardial haemorrhage. The left ventricle was the commonest site of injury (5/6), followed by the right ventricle (2/6) and tricuspid valve (1/6). MACE occurred in 5 patients. Sensitivity and specificity values for CMR at predicting MACE were 60% (15-95) and 81% (54-96), which compared favourably with other tests. CONCLUSION In this pilot trial, CMR was found to give detailed anatomic information of myocardial injury in patients with suspected BCI, and may have a role in the diagnosis and management of patients with suspected BCI.

Abstract
Multiply injured patients represent a particularly demanding subgroup of trauma patients as they require urgent simultaneous clinical assessments using physical examination, ultrasound and invasive monitoring together with critical management, including tracheal intubation, thoracostomies and central venous access. Concurrent access to multiple body regions is essential to facilitate the concept of 'horizontal' resuscitation. The current positioning of trauma patient, with arms adducted, restricts this approach. Instead, the therapeutic cruciform positioning, with arms abducted at 90°, allows planning and performing of multiple life-saving interventions simultaneously. This positioning also provides a practical surgical field with improved sterility and procedural access.

Abstract
Prediction of post-concussive syndrome after apparent mild traumatic brain injury (TBI) and subsequent cognitive recovery remains challenging, with substantial limitations of current methods of cognitive testing. This pilot study aimed to determine if levels of micro ribonucleic acids (RNAs) circulating in plasma are altered following TBI, and if changes to levels of such biomarkers over time could assist in determination of prognosis after TBI. Patients were enrolled after TBI on presentation to the Emergency Department and allocated to three groups: A - TBI (physical trauma to the head), witnessed loss of consciousness, amnesia, GCS=15, a normal CT Brain and a recorded first pass after post-traumatic amnesia (PTA) scale; B TBI, witnessed LOC, amnesia, GCS=15, a normal CT brain and a PTA scale test fail and: C - TBI and initial GCS <13 on arrival to the ED. Venous blood was collected at three time points (arrival, day 5 and day 30). Isolation of cell-free total RNA was then assayed using a custom miRNA PCR array. Two micro-RNAs, mir142-3p and mir423-3p demonstrated potential clinical utility differentiating patients after mild head injury into those at greater risk of developing amnesia and therefore, post-concussive syndromes. In addition, these miRNA demonstrated a decrease in expression over time, possibly indicative of brain healing after the injury. Further evaluation of these identified miRNA markers with larger patient cohorts, correlation with clinical symptoms and analysis over longer time periods are essential next steps in developing objective markers of severity of TBI.

Abstract
BACKGROUND AND OBJECTIVES CT of the brain (CTB) is one of the most common radiological investigations performed in the emergency department (ED). Emergency clinicians rely upon this imaging modality to aid diagnosis and guide management. However, their capacity to accurately interpret CTB is unclear. This systematic review aims to determine this capacity and identify the potential need for interventions directed towards improving the ability of emergency clinicians in this important area. METHODS A systematic review of the literature was conducted without date restrictions. We searched MEDLINE, EMBASE and Cochrane databases and studies reporting the primary outcome of concordance of CTB interpretation between a non-radiologist and a radiology specialist were identified. Studies were assessed for heterogeneity and a subgroup analysis of pooled data based on medical specialty was carried out to specifically identify the concordance of ED clinicians. The quality of evidence was assessed using the GRADE criteria. RESULTS There were 21 studies included in this review. Among the included studies, 12 reported on the concordance of emergency clinicians, 5 reported on radiology trainees and 4 on surgeons. Clinical and statistical heterogeneity between studies was high (I2=97.8%, p<0.01). The concordance in the emergency subgroup was the lowest among all subgroups with a range of 0.63-0.95 and a clinically significant error rate ranging from 0.02 to 0.24. CONCLUSIONS Heterogeneity and the presence of bias limit our confidence in these findings. However, the variance in the interpretation of CTB between emergency clinicians and radiologists suggests that interventions towards improving accuracy may be useful.

Abstract
OBJECTIVE To determine the proportion of non-motorised road users involved in road traffic crashes that presents to hospital intoxicated. METHODS We undertook a retrospective cohort study using data collected from the Alfred Trauma Registry. All patients presenting to an adult major trauma centre in Victoria, Australia from July 2009 to June 2014 who were involved in a road traffic crash as a non-motorised road user - pedestrians, pedal-cyclists, non-motorised scooter users, horse riders - were included. Patients who had a blood alcohol measurement were included, and intoxication was defined as a blood alcohol concentration ≥0.05 g/100 mL. RESULTS There were 1323 patients included for analysis with data on presenting blood alcohol concentration. Alcohol was detected in 248 (18.7%; 95% CI: 16.7-20.9) patients, whereas 211 (15.9%; 95% CI: 14.1-18.0) were intoxicated. Among all included pedestrians, 161 (24.7%) were intoxicated; among all included pedal-cyclists, 47 (7.3%) were intoxicated. Intoxicated patients were significantly younger, and a higher proportion were males and more likely to present after hours and on public holidays (P < 0.01). Survival to hospital discharge and inpatient rehabilitation requirements were similar among intoxicated and non-intoxicated patients. CONCLUSIONS Intoxication was common among non-motorised road users, and the proportion of intoxicated patients in this subgroup appears unchanged over time despite public awareness programmes. The true burden of intoxication in non-motorised road users remains unknown because of a lack of routine testing. Legislation directed at testing for intoxication of non-motorised users and introduction of penalties should be considered to improve safety of all road users.

What is the purpose of log roll examination in the unconscious adult trauma patient during trauma reception? Emerg Med J 2016; 33:632-5.

Abstract
BACKGROUND During assessment after injury, the log roll examination, in particular palpation of the thoracolumbar spine, has low sensitivity for detecting spinal injury. The manoeuvre itself requires a pause during trauma resuscitation. The aim of this study was to assess the utility of the log roll examination in unconscious trauma patients for the diagnosis of soft tissue and thoracolumbar spine injuries. METHODS A retrospective cohort study was undertaken, reviewing the cases of unconscious (Glasgow Coma Scale (GCS) <9) and/or intubated major trauma (Injury Severity Scale (ISS) >12, abbreviated injury scale 2008) patients from the Alfred Trauma Registry, over a 2-year period from January 2011 to December 2012. Log roll examination findings, as documented in the medical record, were compared with CT reports. Out of the 624 screened records, 222 (35.6%) were excluded as the log roll or CT/MRI had not been performed. RESULTS There were a total of 2028 major trauma presentations to the Alfred Hospital Emergency and Trauma Centre during the study period. Excluded cases comprised 147 patients who did not have a documented log roll, and 75 patients who did not have a CT or MRI. Of the 402 cases that met inclusion criteria, 35.3% had a thoracolumbar fracture, and the sensitivity of log roll examination was found to be 27.5%, with a specificity of 91%. The negative likelihood ratio for abnormalities on log roll was low (0.8). CONCLUSIONS Examination of the back in unconscious trauma patients could be limited to visual inspection only to allow identification of penetrating wounds and other soft tissue injuries (including of the posterior scalp) and removal of foreign bodies, in patients planned for CT scans. The low sensitivity and poor negative likelihood ratio suggest that a normal log roll examination does not accurately predict the absence of bony injury to the thoracolumbar spine.

Abstract
Introduction: Traumatic haemorrhagic shock can be difficult to diagnose. Models for predicting critical bleeding and massive transfusion have been developed to aid clinicians. The aim of this review is to outline the various available models and report on their performance and validation. Methods: A review of the English and non-English literature in Medline, PubMed and Google Scholar was conducted from 1990 to September 2015. We combined several terms for i) haemorrhage AND ii) prediction, in the setting of iii) trauma. We included models that had at least two data points. We extracted information about the models, their developments, performance and validation. Results: There were 36 different models identified that diagnose critical bleeding, which included a total of 36 unique variables. All models were developed retrospectively. The models performed with variable predictive abilities–the most superior with an area under the receiver operating characteristics curve of 0.985, but included detailed findings on imaging and was based on a small cohort. The most commonly included variable was systolic blood pressure, featuring in all but five models. Pattern or mechanism of injury were used by 16 models. Pathology results were used by 15 models, of which nine included base deficit and eight models included haemoglobin. Imaging was utilised in eight models. Thirteen models were known to be validated, with only one being prospectively validated. Conclusions: Several models for predicting critical bleeding exist, however none were deemed accurate enough to dictate treatment. Potential areas of improvement identified include measures of variability in vital signs and point of care imaging and pathology testing.
