Critical Care Management of Patients After Cardiac Arrest: A Scientific Statement from the American Heart Association and Neurocritical Care Society

The critical care management of patients after cardiac arrest is burdened by a lack of high-quality clinical studies and the resultant lack of high-certainty evidence. This results in limited practice guideline recommendations, which may lead to uncertainty and variability in management. Critical care management is crucial in patients after cardiac arrest and affects outcome. Although guidelines address some relevant topics (including temperature control and neurological prognostication of comatose survivors, 2 topics for which there are more robust clinical studies), many important subject areas have limited or nonexistent clinical studies, leading to the absence of guidelines or low-certainty evidence. The American Heart Association Emergency Cardiovascular Care Committee and the Neurocritical Care Society collaborated to address this gap by organizing an expert consensus panel and conference. Twenty-four experienced practitioners (including physicians, nurses, pharmacists, and a respiratory therapist) from multiple medical specialties, levels, institutions, and countries made up the panel. Topics were identified and prioritized by the panel and arranged by organ system to facilitate discussion, debate, and consensus building. Statements related to postarrest management were generated, and 80% agreement was required to approve a statement. Voting was anonymous and web based. Topics addressed include neurological, cardiac, pulmonary, hematological, infectious, gastrointestinal, endocrine, and general critical care management. Areas of uncertainty, areas for which no consensus was reached, and future research directions are also included. Until high-quality studies that inform practice guidelines in these areas are available, the expert panel consensus statements that are provided can advise clinicians on the critical care management of patients after cardiac arrest.

Sport-related major trauma incidence in young people and adults in England and Wales: a national registry-based study

OBJECTIVES

Data on sport and physical activity (PA) injury risk can guide intervention and prevention efforts. However, there are limited national-level data, and no estimates for England or Wales. This study sought to estimate sport and PA-related major trauma incidence in England and Wales.

METHODS

Nationwide, hospital registry-based cohort study between January 2012 and December 2017. Following Trauma Audit and Research Network Registry Research Committee approval, data were extracted in April 2018 for people ≥16 years of age, admitted following sport or PA-related injury in England and Wales. The population-based Active Lives Survey was used to estimate national sport and PA participation (ie, running, cycling, fitness activities). The cumulative injury incidence rate was estimated for each activity. Injury severity was described by Injury Severity Score (ISS) >15.

RESULTS

11 702 trauma incidents occurred (mean age 41.2±16.2 years, 59.0% male), with an ISS >15 for 28.0% of cases, and 1.3% were fatal. The overall annual injury incidence rate was 5.40 injuries per 100 000 participants. The incidence rate was higher in men (6.44 per 100 000) than women (3.34 per 100 000), and for sporting activities (9.88 per 100 000) than cycling (2.81 per 100 000), fitness (0.21 per 100 000) or walking (0.03 per 100 000). The highest annual incidence rate activities were motorsports (532.31 per 100 000), equestrian (235.28 per 100 000) and gliding (190.81 per 100 000).

CONCLUSION

Injury incidence was higher in motorsports, equestrian activity and gliding. Targeted prevention in high-risk activities may reduce admissions and their associated burden, facilitating safer sport and PA participation.

The Clinical Course of Paranasal Sinus Mucocoeles-A Retrospective Case Series

Paranasal sinus mucocoeles can be secondary to chronic rhinosinusitis and can result in intra-orbital and intra-cranial complications requiring surgical management. The natural history of conservatively managed mucocoeles is not well established. We aimed to quantify the proportion of radiologically identified paranasal sinus mucocoeles resulting in complications over 10 years. We retrospectively reviewed anonymised data on radiologically diagnosed mucocoeles between 2011 and 2021 at two UK hospitals. We collected data on age at presentation, extent of sinus involvement, management and complications. We identified 60 patients with mucocoeles, of which 35 (58%) were incidental findings from radiological investigations. The mean age was 58 years. Fifteen patients (25%) were managed surgically and one presented with recurrence following surgery. Overall, six patients (10%) had an intra-orbital extension of their mucocoele and three (5%) had an intra-cranial extension. There was no difference in the rates of intra-cranial extension between conservative and surgical cases but surgical cases included a higher rate of intra-orbital extensions (27% vs. 4%, p = 0.01). The proportion of patients requiring surgical intervention in this study is low. Incidental and asymptomatic mucocoeles have a relatively benign disease course and selected uncomplicated cases can be considered for conservative management with serial scanning at 12 months.

The Etiology of Trauma in Geriatric Traumatic Patients Refer to an Academic Trauma Center: A Cross Sectional Study

Objective

Geriatric trauma refers to injuries sustained by elderly individuals, typically those aged 65 years and older. The management of geriatric trauma in the Emergency Department requires a comprehensive approach that takes into account the physiological changes associated with aging, as well as the increased vulnerability and complexity of injuries in this population.

Methods

This is a cross-sectional study aimed at evaluating the etiology of trauma in geriatric patients referred to the ED of level-1 an academic center. All patients with complaints of trauma are evaluated and patients over 65 years enrolled in the study. Data were analyzed by SPSS 26.

Results

319 patients were investigated, 49.8% male and 50.2% female. The most common underlying diseases are high blood pressure, diabetes type 2, and ischemic heart disease. The most common trauma cause was falling from the same level (48.9%), followed by a fall from a height (16.6%), accidents with cars (16%), and motorcycles (9.1%). The most common injury was extremities trauma (71.5%) following head trauma (13.2%) and chest trauma (6%). The severity of injury in extremities was higher in women, and chest trauma was more severe in men.

Conclusion

The fall and subsequent car accident had the highest frequency as a cause of trauma in elderly patients admitted to our academic trauma center. Hypertension and diabetes have also been the most common underlying diseases. Head and neck injuries are life-threatening and critical in a larger number of patients than other injuries, and protecting them can be effective in reducing mortality and serious injuries in elderly trauma patients.

Investigating Length of Stay Patterns and Its Predictors in the South Wales Trauma Network

Background

Length of stay (LOS) is frequently employed as a performance metric for trauma care. Following the establishment of the trauma network worldwide, the assessment and prediction of LOS in different levels of trauma centres have been extensively studied. However, assessing the total patient length of stay from a whole trauma network perspective is unclear. The objective of this study was to systematically analyse the overall Length of Stay (LOS) pattern within the SWTN before its establishment and in the immediate time after its foundation and, secondly, to assess the association between relevant impact factors and LOS.

Methodology

A retrospective secondary analysis based on the trauma admission dataset from Trauma Audit and Research Network(TARN) dataset was conducted. The studied sample covered around 18000 patients admitted to trauma centres from South Wales Major trauma network between January 2012 and October 2021. The primary outcome is the total length of stay in the trauma network. Statistical tests were applied to examine the difference between normal and outlier LOS. Data visualisation was utilised to demonstrate the LOS patterns and potential association between LOS and relevant demographic and clinical predictors.

Results

The distribution of length of stay in SWTN follows a right-skewed distribution with a median of 10 (IQR, 5-18) and a mean of 15.92 days. There were 1520 patients with outliers for LOS. A significant difference (p¡ 0.05) was found between the normal and outlier groups of LOS based on demographic (age, gender and residential information) and clinical characteristics(ward type, maximum of anatomically-based injury severity score(AIS) and probability of survival). Age group, maximum AIS score on specific injured region, ward type and its interaction effect with the number of admissions may associated with the LOS. Specifically, patients admitted to the geriatric ward exhibited notably prolonged LOS, and individuals with more than 2 admissions to long-term care and recovery-related wards such as neurosurgical rehabilitation, spinal injuries and burns wards also displayed elevated LOS.

Conclusion

Our finding supports prior evidence indicating elderly people are vulnerable to longer stays. Moreover, concerning the types of admission wards, patients admitted to rehabilitation wards who underwent more than 2 hospitalisations also faced an increased risk of prolonged stay. Based on these results, policymakers and healthcare providers should contemplate expanding the allocation of medical resources to this demographic to mitigate the length of stay and optimise associated healthcare costs.

Serum Levels of Pro-Brain Natriuretic Peptide and the Diagnosis and Prognosis of Cardiac Syncope

Objective

Recently, different serum markers have been used for the diagnosis and prognosis of acute heart diseases in emergency departments. To determine such a role, the present study was designed and conducted.

Methods

This is an analytical cross-sectional study conducted on patients with syncope complaints. The patients enrolled in the study based on the inclusion and exclusion criteria and underwent initial evaluations, including collecting a history, physical examination, ECG, blood sugar measurement, and, if necessary, brain CT scan, Doppler echocardiography, and CTA.

Results

This study included 100 participants who complained of syncope. The results showed that 19% and 81% of the subjects suffered from cardiac and non-cardiac syncope, respectively. The average Pro BNP of the studied individuals was 196.06±128.45 pg/mL. According to the results, age and length of hospitalization had a positive and significant relationship with the average Pro BNP (p<0.01). Individuals with positive TPI, cardiac syncope, and abnormal ECG or Doppler findings had significantly higher average Pro BNP levels (p<0.01). The results of the diagnostic value of Pro BNP in diagnosing cardiac syncope also showed that its sensitivity and specificity were 94.73% and 56.79%, respectively.

Conclusion

The results of this study showed that the increase in the Pro BNP values was associated with age, length of hospitalization, and ECG abnormalities. In addition, as an independent marker, Pro BNP had optimal acceptability in identifying cardiac syncope cases.

Quad bike related trauma in Ireland

INTRODUCTION

A quad bike or an all-terrain vehicle is a four-wheeled powered vehicle generally designed for off-road use. They are widely used for farm-related work and more recently for recreational purposes. The potential for serious injury and death with quad bike use is a growing public health concern. There is an inherent instability in their design and they are typically used on rugged terrain characterised by dangerous driving surfaces. This study examines quad bike related trauma in Ireland using a national trauma registry to identify patient demographics, injury mechanism and type, treatments received and outcomes.

METHODS

All quad bike related trauma cases recorded on the Major Trauma Audit (MTA), National Office of Clinical Audit in Ireland for the period 2014-2019 were gathered and analysed.

RESULTS

There were 69 cases identified and 63 (91 %) of these were male. The median (IQR) age was 27 (19 - 49.1). There were 25 % (n = 17) aged 0-18 years, 64 % (n = 44) aged 19-65 and 12 % (n = 8) aged greater than 65 years. The median injury severity score (ISS) was 10 (IQR 9-22). The most severely injured body region was the head (n = 21, 30 %). No helmet use was recorded in 50 % (n = 34) of cases. October recorded the highest number of cases (n = 9, 13 %), and Sunday was the most common day (n = 17, 25 %). The median length of hospital stay was five days (IQR 3-9). One patient died after arrival to hospital.

CONCLUSION

Quad bike related trauma predominantly affects a young male cohort with serious injury characteristics. A sizeable proportion of patients are under 18 years of age. This data can better inform national policies and public awareness campaigns targeting this trauma subset. The head was the most common severely injured body region, highlighting the potential need for legislative intervention regarding mandatory helmet use. A large cohort of patients required transfer for definitive care which has implications for trauma care pathways and advocates for the development of an integrated trauma system in Ireland.

Lack of regional pathways impact on surgical delay: Analysis of the Orthopaedic Trauma Hospital Outcomes-Patient Operative Delays (ORTHOPOD) study

INTRODUCTION

Current practice following injury within the United Kingdom is to receive surgery, at the institution of first contact regardless of ability to provide timely intervention and inconsiderate of neighbouring hospital resource and capacity. This can lead to a mismatch of demand and capacity, delayed surgery and stress within hospital systems, particularly with regards to elective services. We demonstrate through a multicentre, multinational study, the impact of this at scale.

METHODOLOGY

ORTHOPOD data collection period was between 22/08/2022 and 16/10/2022 and consisted of two arms. Arm 1 captured orthopaedic trauma caseload and capacity in terms of sessions available per centre and patients awaiting surgery per centre per given week. Arm 2 recorded patient and injury demographics, time of decision making, outpatient and inpatient timeframes as well as time to surgery. Hand and spine cases were excluded. For this regional comparison, regional trauma networks with a minimum of four centres enroled onto the ORTHOPOD study were exclusively analysed.

RESULTS

Following analysis of 11,202 patient episodes across 30 hospitals we found no movement of any patient between hospitals to enable prompt surgery. There is no current system to move patients, between regional centres despite clear discrepancies in workload per capacity across the United Kingdom. Many patients wait for days for surgery when simple transfer to a neighbouring hospital (within 10 miles in many instances) would result in prompt care within national guidelines.

CONCLUSION

Most trauma patients in the United Kingdom are managed exclusively at the place of first presentation, with no consideration of alternative pathways to local hospitals that may, at that time, offer increased operative capacity and a shorter waiting time. There is no oversight of trauma workload per capacity at neighbouring hospitals within a regional trauma network. This leads to a marked disparity in waiting time to surgery, and subsequently it can be inferred but not proven, poorer patient experience and outcomes. This inevitably leads to a strain on the overall trauma system and across several centres can impact on elective surgery recovery. We propose the consideration of inter-regional network collaboration, aligned with the Major Trauma System.

Challenges and opportunities to improve efficiency and quality of prehospital emergency care using an mHealth platform: Qualitative study in Rwanda

Introduction

Prompt, high-quality pre-hospital emergency medical services (EMS) can significantly reduce morbidity and mortality. The goal of this study was to identify factors that compromise efficiency and quality of pre-hospital emergency care in Rwanda, and explore the opportunities for a mobile health (mHealth) tool to address these challenges.

Methods

In-depth interviews were conducted with 21 individuals representing four stakeholder groups: EMS dispatch staff, ambulance staff, hospital staff, and policymakers. A semi-structured interview guide explored participants' perspectives on all aspects of the pre-hospital emergency care continuum, from receiving a call at dispatch to hospital handover. Participants were asked how the current system could be improved, and the potential utility of an mHealth tool to address existing challenges. Interviews were audio-recorded, and transcripts were thematically analyzed using NVivo.

Results

Stakeholders identified factors that compromise the efficiency and quality of care across the prehospital emergency care continuum: triage at dispatch, dispatching the ambulance, locating the emergency, coordinating patient care at scene, preparing the receiving hospital, and patient handover to the hospital. They identified four areas where an mHealth tool could improve care: efficient location of the emergency, streamline communication for decision making, documentation with real-time communication, and routine data for quality improvement. While stakeholders identified advantages of an mHealth tool, they also mentioned challenges that would need to be addressed, namely: limited internet bandwidth, capacity to maintain and update software, and risks of data security breaches that could lead to stolen or lost data.

Conclusion

Despite the success of Rwanda's EMS system, this study highlights factors across the care continuum that could compromise quality and efficiency of prehospital emergency care. Mobile health tools hold great promise to address these challenges, but contextual issues need to be considered to ensure sustainability of use.

Plasma interleukin responses as predictors of outcome stratification in patients after major trauma: a prospective observational two centre study

Background and objectives

There is a need to develop objective risk stratification tools to define efficient care pathways for trauma patients. Biomarker-based point of care testing may strengthen existing clinical tools currently available for this purpose. The dysregulation of pro- and anti-inflammatory cytokines in the pathogenesis of organ failure is well recognised. This study was carried out to evaluate whether blood concentrations of IL-6, IL-10, and IL-6:IL-10 ratios in the early stages of the illness are significantly different in patients with worsening organ function.

Materials and methods

In this prospective observational cohort study, plasma concentrations of IL-6 and IL-10 on days 1, 3 and 5 were measured in 91 major trauma patients using a multiplexed cytometric bead array approach. A composite measure of adverse outcome - defined as SOFA ≥ 2 or mortality at 7 days, was the primary outcome. IL-6 and IL-10 concentrations in early samples (days 1, 3 & 5) in patients who developed SOFA ≥ 2 on day 7 were compared against those who did not. Similar composite outcome groups at day 5 and in groups with worsening or improving SOFA scores (ΔSOFA) at days 7 and 5 were undertaken as secondary analyses.

Results

Stratification on day 7, 44 (48%) patients showed adverse outcomes. These adverse outcomes associated with significantly greater IL-6 concentrations on days 1 and 5 (Day 1: 47.65 [23.24-78.68] Vs 73.69 [39.93 - 118.07] pg/mL, P = 0.040 and Day 5: 12.85 [5.80-19.51] Vs 28.90 [8.78-74.08] pg/mL; P = 0.0019). Similarly, IL-10 levels were significantly greater in the adverse outcome group on days 3 and 5 (Day 3: 2.54 [1.76-3.19] Vs 3.16 [2.68-4.21] pg/mL; P = 0.044 and Day 5: 2.03 [1.65-2.55] Vs 2.90 [2.00-5.06] pg/mL; P <0.001). IL-6 and IL-10 concentrations were also significantly elevated in the adverse outcome groups at day 3 and day 5 when stratified on day 5 outcomes. Both IL-6 and IL-6:IL-10 were found to be significantly elevated on days 1 and 3 when stratified based on ΔSOFA at day 5. This significance was lost when stratified on day 7 scores.

Conclusions

Early IL-6 and IL-10 concentrations are significantly greater in patients who develop worsening organ functions downstream. These differences may provide an alternate biomarker-based approach to strengthen risk stratification in trauma patients.

Emergency Department Resuscitative Endovascular Balloon Occlusion of the Aorta in Trauma Patients With Exsanguinating Hemorrhage: The UK-REBOA Randomized Clinical Trial

Importance

Bleeding is the most common cause of preventable death after trauma.

Objective

To determine the effectiveness of resuscitative endovascular balloon occlusion of the aorta (REBOA) when used in the emergency department along with standard care vs standard care alone on mortality in trauma patients with exsanguinating hemorrhage.

Design, Setting, and Participants

Pragmatic, bayesian, randomized clinical trial conducted at 16 major trauma centers in the UK. Patients aged 16 years or older with exsanguinating hemorrhage were enrolled between October 2017 and March 2022 and followed up for 90 days.

Intervention

Patients were randomly assigned (1:1 allocation) to a strategy that included REBOA and standard care (n = 46) or standard care alone (n = 44).

Main Outcomes and Measures

The primary outcome was all-cause mortality at 90 days. Ten secondary outcomes included mortality at 6 months, while in the hospital, and within 24 hours, 6 hours, or 3 hours; the need for definitive hemorrhage control procedures; time to commencement of definitive hemorrhage control procedures; complications; length of stay; blood product use; and cause of death.

Results

Of the 90 patients (median age, 41 years [IQR, 31-59 years]; 62 [69%] were male; and the median Injury Severity Score was 41 [IQR, 29-50]) randomized, 89 were included in the primary outcome analysis because 1 patient in the standard care alone group declined to provide consent for continued participation and data collection 4 days after enrollment. At 90 days, 25 of 46 patients (54%) had experienced all-cause mortality in the REBOA and standard care group vs 18 of 43 patients (42%) in the standard care alone group (odds ratio [OR], 1.58 [95% credible interval, 0.72-3.52]; posterior probability of an OR >1 [indicating increased odds of death with REBOA], 86.9%). Among the 10 secondary outcomes, the ORs for mortality and the posterior probabilities of an OR greater than 1 for 6-month, in-hospital, and 24-, 6-, or 3-hour mortality were all increased in the REBOA and standard care group, and the ORs were increased with earlier mortality end points. There were more deaths due to bleeding in the REBOA and standard care group (8 of 25 patients [32%]) than in standard care alone group (3 of 18 patients [17%]), and most occurred within 24 hours.

Conclusions and Relevance

In trauma patients with exsanguinating hemorrhage, a strategy of REBOA and standard care in the emergency department does not reduce, and may increase, mortality compared with standard care alone.

The incidence and impact of 'Tandem Neurotrauma'

Introduction

The epidemiology and prognosis of the isolated traumatic brain injury (TBI) and spinal cord injury (SCI) are well studied. However, the knowledge of the impact of concurrent neurotrauma is very limited.

Research questions

To characterize the longitudinal incidence of concurrent TBI and SCI and to investigate their combined impact on clinical care and outcomes, compared to a comparative but isolated SCI or TBI.

Materials and methods

Data from 167,793 patients in the Trauma Audit and Research Network (TARN) registry collected in England and Wales between 2008 and 2018 were analysed. Tandem neurotrauma was defined as patients with concurrent TBI and SCI. The patient with isolated TBI or SCI was matched to the patient with tandem neurotrauma using propensity scores.

Results

The incidence of tandem neurotrauma increased tenfold between 2008 and 2018, from 0.21 to 2.21 per 100,000 person-years. Patients in the tandem neurotrauma group were more likely to require multiple surgeries, ICU admission, longer ICU and hospital LOS, higher 30-day mortality, and were more likely to be transferred to acute hospitals and rehabilitation or suffer death at discharge, compared to patients with isolated TBI. Likewise, individuals with tandem neurotrauma compared to those with isolated SCI had a higher tendency to receive more than one surgery, ICU admission, longer LOS for ICU and higher mortality either at 30-day follow-up or at discharge.

Discussion and conclusions

The incidence of tandem neurotrauma has increased steadily during the past decade. Its occurrence leads to greater mortality and care requirements, particularly when compared to TBI alone. Further investigations are warranted to improve outcomes in tandem neurotrauma.

On Scene Injury Severity Prediction (OSISP) model for trauma developed using the Swedish Trauma Registry

BACKGROUND

Providing optimal care for trauma, the leading cause of death for young adults, remains a challenge e.g., due to field triage limitations in assessing a patient's condition and deciding on transport destination. Data-driven On Scene Injury Severity Prediction (OSISP) models for motor vehicle crashes have shown potential for providing real-time decision support. The objective of this study is therefore to evaluate if an Artificial Intelligence (AI) based clinical decision support system can identify severely injured trauma patients in the prehospital setting.

METHODS

The Swedish Trauma Registry was used to train and validate five models - Logistic Regression, Random Forest, XGBoost, Support Vector Machine and Artificial Neural Network - in a stratified 10-fold cross validation setting and hold-out analysis. The models performed binary classification of the New Injury Severity Score and were evaluated using accuracy metrics, area under the receiver operating characteristic curve (AUC) and Precision-Recall curve (AUCPR), and under- and overtriage rates.

RESULTS

There were 75,602 registrations between 2013-2020 and 47,357 (62.6%) remained after eligibility criteria were applied. Models were based on 21 predictors, including injury location. From the clinical outcome, about 40% of patients were undertriaged and 46% were overtriaged. Models demonstrated potential for improved triaging and yielded AUC between 0.80-0.89 and AUCPR between 0.43-0.62.

CONCLUSIONS

AI based OSISP models have potential to provide support during assessment of injury severity. The findings may be used for developing tools to complement field triage protocols, with potential to improve prehospital trauma care and thereby reduce morbidity and mortality for a large patient population.

Implementing findings from (hip) fracture registries

The National Health Service in England has successfully used learning from its National Hip Fracture Database to drive improvements in care of the most frail orthopaedic trauma patients. While this could simply be viewed as achieving its primary function, the learning with regard to meaningful change that resulted has been applied across the other aspects of trauma to achieve improvements including multiply injured patients within trauma systems (Trauma Audit and Research Network (TARN)) and community level trauma. This work looks at the lessons that can be learned through the inception and running of a national database, in particular how it can be used as a template to achieve improved care in other aspects of orthopaedic trauma. It explains the UK system and the navigation of this to gain political and administrative traction in the creation of a national network and how this momentum was used to achieve a complete overhaul of the trauma system. There are lessons that are applicable across all healthcare systems.

Incidence and outcomes of major trauma patients with thoracic injuries and rib fractures in Aotearoa New Zealand

INTRODUCTION

Thoracic trauma represents a significant burden of disease in Aotearoa, New Zealand (AoNZ). To date, no study has examined the incidence or outcomes of patients suffering major thoracic trauma, or major trauma and rib fractures in AoNZ.

METHODS

A 6 year retrospective study of all major trauma (Injury Severity Score >12) patients in AoNZ was performed. The National Trauma Registry was searched to identify patients. The National Minimum Data Set was searched for all ICD-10 codes associated with surgical stabilisation of rib fractures (SSRF). Poisson regression was used to determine the change in incidence rate over the study period adjusted for age with the logarithm of population size as the offset variable. The incidence rate ratios (IRR) with 95% confidence intervals (CI) were reported.

RESULTS

12,218 patients sustained major trauma. 7,059 (57.8%) of these patients sustained thoracic injuries. Of these patients, 5,585 (79.1%) sustained rib fractures, and 180 (3.2%) proceeded to SSRF. A flail segment was observed in 16% of patients with rib fractures. Transport was the mechanism of injury in 53% of patients. During the study the incidence (cases per 100,000 people per year) of major trauma increased from 39.5 to 49.3 (IRR 1.05, 95%CI 1.04 to 1.07, <0.001), the incidence of thoracic injuries from 21.3 to 28.7 (1.07, 95% CI 1.05 to 1.08, <0.001) and the incidence of rib fractures from 16.0 to 22.9 (1.08, 95% CI 1.06 to 1.09, <0.001). SSRF was performed in 3.2% of patients with rib fractures and increased from 0.2 to 0.8 cases per 100,000 people per year (1.27, 95% CI 1.15 to 1.41, <0.001) during the study.

CONCLUSION

This study reports the incidence of major trauma patients with thoracic injury, major trauma patients with rib fractures and the incidence of SSRF in AoNZ. Transport related injuries are the predominant mechanism of injury. The incidence of SSRF was low across AoNZ. To improve the quality of care in AoNZ for major trauma patients with rib fractures, consideration should be made to create national guidelines and robust referral pathways to specialist centres that provide multidisciplinary care including performing SSRF.

Experimental Models of Traumatic Injuries: Do They Capture the Coagulopathy and Underlying Endotheliopathy Induced by Human Trauma?

Trauma-induced coagulopathy (TIC) is a major cause of morbidity and mortality in patients with traumatic injury. It describes the spectrum of coagulation abnormalities that occur because of the trauma itself and the body's response to the trauma. These coagulation abnormalities range from hypocoagulability and hyperfibrinolysis, resulting in potentially fatal bleeding, in the early stages of trauma to hypercoagulability, leading to widespread clot formation, in the later stages. Pathological changes in the vascular endothelium and its regulation of haemostasis, a phenomenon known as the endotheliopathy of trauma (EoT), are thought to underlie TIC. Our understanding of EoT and its contribution to TIC remains in its infancy largely due to the scarcity of experimental research. This review discusses the mechanisms employed by the vascular endothelium to regulate haemostasis and their dysregulation following traumatic injury before providing an overview of the available experimental in vitro and in vivo models of trauma and their applicability for the study of the EoT and its contribution to TIC.

Improving plastic surgery care of hand trauma using the lean thinking model

Plastic surgery trauma care services vary widely between hospitals in the UK. The authors evaluated their plastic surgery trauma service and illustrated the use of lean thinking to successfully implement small interventions to create positive change. The study findings demonstrated an increase in the proportion of patients with trauma being treated in the outpatient clinic rather than in the main theatres. This coincided with an increase in the proportion of patients being treated on the day of presentation to hospital.

Predictors of long-term survival in 5,680 patients admitted to a UK major trauma centre with thoracic injuries

INTRODUCTION

The long-term outcomes of chest trauma are largely unknown. We sought to determine the predictors of in-hospital and long-term survival in patients admitted to a major trauma centre (MTC) with chest injuries and to evaluate spatial patterns of injury in our network area.

METHODS

Retrospective analysis of data collected on the National Trauma Audit Research Network (TARN) database using multivariate analysis and Cox regression analysis. Spatial analysis was performed using ArcGis 10.7.1.

RESULTS

Some 5,680 patients were admitted with chest trauma between December 1999 and December 2019. Median patient age was 45 years and the median Injury Severity Score (ISS) was 20. The proportion of patients who had an operation was 39.8%. Age, blood transfusion, head injury, shock, emergency thoracotomy and heart disease were predictors of hospital mortality (p < 0.05). However, having an operation on concomitant injuries was protective. ISS and Glasgow Coma Score were discriminators of in-hospital mortality (C-indices 0.76 and 0.80, respectively). The 10-year survival values for patients who survived to discharge from hospital and who were aged <40, 50, 60, 70, 80 and >80 years were 99%, 93%, 95%, 87%, 75% and 43%, respectively. Preadmission lung disease and alcohol/drug misuse were poor predictors of long-term survival (p < 0.05). Hotspot analysis revealed the areas with the highest incidents were all close to the MTC.

CONCLUSIONS

The MTC is geographically central to areas with high numbers of trauma incidents. Although emergency thoracotomy was a predictor of poor in-hospital outcomes, having surgery for concomitant injuries improved outcomes. Patients surviving to discharge have good long-term survivals.

The process of identifying major trauma in the older person in a single major trauma centre: A service evaluation

BACKGROUND

Diagnosis of major trauma in the older person is increasingly recognised as clinically challenging with recent reports finding that older patients sustaining major trauma are commonly under-recognised and subsequently are not receiving gold standard major trauma care. This paper is a service evaluation of the processes of major trauma (ISS > 15) care for patients > 65 years presenting to a UK major trauma centre.

AIM

To identify modifiable factors within the patient journey that might inform future service improvement initiatives.

METHODS

TARN audit data and retrospective notes review of 190 patients > 65 presenting to UHS ED from 1st January 2018 - 31st December 2018 who did not receive a level 1 trauma call on arrival were used to achieve the dataset. Descriptive statistics were combined with multiple logistic regression to look for associations between specific process factors and a missed or delayed diagnosis.

RESULTS

The evaluation found that, of the cohort not receiving a level 1 trauma call, 42 (22.1%) patients received a level 2 trauma call; 87 (45.7%) patients were seen initially by a senior clinician, with only 31 (16.3%) patients meeting best practice tariff for consultant within 5 min; 60 (31.5%) patients were seen directly in the resuscitation room; 48 (25.2%) patients received a trauma CT scan with only 27 (14.2%) meeting BPT for CT head within 1 h; 142 (74.7%) patients were admitted to a trauma specialty after discharge from ED. A total of 76 (40%) patients had a missed diagnosis of major trauma with 80 (42%) having a delayed diagnosis. Logistic regression showed a significant association between being seen in a standard initial assessment area (referred to as pitstop in this article) vs the resuscitation room as a first location (p = 0.007) with a delayed diagnosis; and a significant association between plain film imaging vs CT imaging (p = 0.000) and no trauma call vs trauma call (p = 0.009) with a missed diagnosis of major trauma.

CONCLUSION

The findings of this service evaluation suggest that service improvement initiatives should be aimed at the early stages of the patient journey to improve missed or delayed diagnoses of major trauma in this patient group.

National evaluation of trauma teaching for students (NETTS)

Despite the shift towards consultant-led care, many patients with trauma are still seen by junior doctors. Previous research has demonstrated that junior doctors feel unprepared to work in acute care but there is a paucity of recent research in trauma specifically. Thus, a national study is required to investigate the current state of undergraduate trauma teaching and identify specific areas for improvement. Between August and September 2020, a 35-item structured questionnaire was distributed among doctors who graduated from UK medical schools within the last 4 years. The questionnaire retrospectively assessed their experience of trauma teaching at medical school and their confidence to diagnose and manage patients with trauma. 398 responses were recorded from graduates of 39 UK medical schools. With 79.6% reporting only 0-5 hours of bedside trauma teaching and 51.8% reporting less than 20 hours in Accident and Emergency, graduates reported that trauma teaching was deficient compared with other specialties (78.1%). The majority of graduates were not confident in the initial assessment (72.9%) of a patient with trauma and almost all felt that a short course in trauma would be useful (93.7%). 77.4% of students felt that online learning would be beneficial and 92.9% felt that simulation would be useful. There is lack of standardised undergraduate trauma teaching nationally; a formal undergraduate teaching to ensure that new graduates are competent in the management of trauma would be supported by students. It is likely that a blended learning approach, incorporating e-learning with traditional teaching and clinical experience would be well received.

Cost-effectiveness of a purpose-built ward environment and new allied health model of care for major trauma

BACKGROUND

Targeted rehabilitation within the acute inpatient setting could have a substantial impact on improving outcomes for major trauma patients. The aim of this study was to investigate the cost-effectiveness of the introduction of a purpose-built ward environment, and a new allied health model of care (AHMOC) delivered in the acute inpatient setting, in a major trauma population.

METHODS

The statewide trauma registry, the trauma center's data warehouse, and electronic medical record data were used for this observational study. There were three phases: baseline, new ward, and new AHMOC. Cost-effectiveness was measured as cost per quality-adjusted life year using preinjury, hospital discharge, 1-month and 6-month 5-level, EQ-5D utility scores. Total costs included initial acute and inpatient rehabilitation care, as well as outpatient, readmission and ED presentations to 6-months.

RESULTS

Four hundred eleven patients were included. Case-mix was stable between phases. The median (IQR) number of allied health services received by patients was 8 (5-17) at baseline, 10 (5-19) in the new ward phase, and 17 (9-23) in the AHMOC phase. The proportion discharged to rehabilitation was 37% at baseline, 45% with the new ward and 28% with the new AHMOC. Mean (SD) total Australian dollar costs were $69,335 ($141,175) at baseline, $55,943 ($82,706) with the new ward and $37,833 ($49,004) with the AHMOC. The probability of the AHMOC being cost-effective at a willingness-to-pay threshold of $50,000 per quality-adjusted life year was 99.4% compared with baseline and 98% compared with the new ward.

CONCLUSION

The new allied health model of care was found to be a cost-effective intervention. Uptake of this model of allied health care at other trauma centers has the potential to reduce the cost and burden of major trauma.

Do Patients with Diabetes Mellitus and Polytrauma Continue to Have Worse Outcomes?

The management of patients with multiple injuries remains challenging. Patients presenting with comorbidities, such as diabetes mellitus, may have additional unpredictable outcomes with increased mortality. Therefore, we aim to investigate the impact of major trauma centres in the UK on the outcomes of polytrauma patients with diabetes. The Trauma Audit and Research Network was used to identify polytrauma patients presenting to centres in England and Wales between 2012 and 2019. In total, 32,345 patients were thereby included and divided into three groups: 2271 with diabetes, 16,319 with comorbidities other than diabetes and 13,755 who had no comorbidities. Despite an overall increase in diabetic prevalence compared to previously published data, mortality was reduced in all groups, but diabetic patient mortality remained higher than in the other groups. Interestingly, increasing Injury Severity Score (ISS) and age were associated with increasing mortality, whereas the presence of diabetes, even when taking into consideration age, ISS and Glasgow Coma Score, led to an increase in the prediction of mortality with an odds ratio of 1.36 (p < 0.0001). The prevalence of diabetes mellitus in polytrauma patients has increased, and diabetes remains an independent risk factor for mortality following polytrauma.

Trends in mortality outcomes of hospital-admitted injury in Victoria, Australia 2001-2021

Due to advancements in trauma treatment methods, it is expected that survivability of hospital-admitted injuries gradually improves over time. However, measurement of trends in all-cause injury survivability is complicated by changes in case mix, demographics and hospital admission policy. The aim of this study is to determine trends in hospital-admitted injury survivability in Victoria, Australia, taking case-mix and patient demographics into account, and to explore the potential impact of changes in hospital admission practices. Injury admission records (ICD-10-AM codes S00-T75 and T79) between 1 July 2001 and 30 June 2021 were extracted from the Victorian Admitted Episodes Dataset. ICD-based Injury Severity Score (ICISS) calculated from Survival Risk Ratios for Victoria was used as an injury severity measure. Death-in-hospital was modelled as a function of financial year, adjusting for age group, sex and ICISS, as well as admission type and length of stay. There were 19,064 in-hospital deaths recorded in 2,362,991 injury-related hospital admissions in 2001/02-2020/21. Rates of in-hospital death decreased from 1.00% (866/86,998) in 2001/02 to 0.72% (1115/154,009) in 2020/21. ICISS was a good predictor of in-hospital death with an area-under-the-curve of 0.91. In-hospital death was associated with financial year (Odds Ratio 0.950 [95%CI 0.947, 0.952]), in logistic regression modelling adjusted for ICISS, age and sex. In stratified modelling, decreasing injury death trends were observed in each of the top 10 injury diagnoses (together constituting > 50% of cases). Admission type and length of stay were added to the model: these did not alter the effect of year on in-hospital death. In conclusion, a 28% reduction in rates of in-hospital deaths in Victoria was observed over the 20-year study period, in spite of aging of the injured population. This amounts to 1222 additional lives saved in 2020/21 alone. Survival Risk Ratios therefore change markedly over time. A better understanding of the drivers of positive change will help to further reduce the injury burden in Victoria.

National Neurotrauma Registry Data in Low- and Middle-Income Countries - Current Status and Future Requirements Comment on "Neurotrauma Surveillance in National Registries of Low- and Middle-Income Countries: A Scoping Review and Comparative Analysis of Data Dictionaries"

Since 1990 National Trauma Registries, - taking the form of "not for profit" small and medium enterprises - have been integral to improvementsin major injury case fatality in high-income settings. This is laudable but unsatisfactory as globally most years of life lost to injury occur in low- and middle-income countries (LMICs). International Journal of Health Policy and Management, recently published a scoping review of neurotrauma registries in LMICs by Barthelemy et al; from this the commentary reflects on the state of the art and how these LMIC registries could be taken to "the next level" as meaningful tools for improving major injury patient care.

Trauma deaths of hospitalized patients in Abu Dhabi Emirate: a retrospective descriptive study

AIM

To study the epidemiology and pattern of trauma-related deaths of hospitalized patients in Abu Dhabi Emirate, United Arab Emirates, in order to improve trauma management and injury prevention.

METHODS

The Abu Dhabi Trauma Registry prospectively collects data of all hospitalized trauma patients from seven major trauma centres in Abu Dhabi Emirate. We studied all patients who died on arrival or after admission to these hospitals from January 2014 to December 2019.

RESULTS

There were 453 deaths constituting 13.5% of all trauma deaths in the Abu Dhabi Emirate. The median (IQR) age of the patients was 33 (25-45) years, and 82% were males. 85% of the deaths occurred in the emergency department (ED) and the intensive care unit (ICU). Motor vehicle collision (63.8%) was the leading cause of death. 45.5% of the patients had head injury. Two of the seven hospitals admitted around 50% of all patients but accounted for only 25.8% of the total deaths (p < 0.001). Those who died in the ward (7%) were significantly older, median (IQR) age: of 65.5 (31.75-82.25) years, (p < 0.001), 34.4% of them were females (p = 0.09). The median (IQR) GCS of those who died in the ward was 15 (5.75-15) compared with 3 (3-3) for those who died in ED and ICU (P < 0.001).

CONCLUSIONS

Death from trauma predominantly affects young males with motor traffic collision as the leading cause. Over 85% of in-hospital deaths occur in the ICU and ED, mainly from head injuries. Injury prevention of traffic collisions through enforcement of law and improved hospital care in the ED and ICU will reduce trauma death.

Severe trauma with associated pelvic fractures: The impact of regional trauma networks on clinical outcome

Lately, the care of severely injured patients in the United Kingdom has undergone a significant transformation. The establishment of regional trauma networks (RTN) with designated Major Trauma Centers (MTCs) and satellite hospitals called Trauma Units (TUs) has centralized the care of severely injured patients in the MTCs. Pelvic fractures are notoriously linked with hypovolemic shock or even death from excessive blood loss. The aim of this prospective cohort study is to compare the profile of severely injured patients with combined pelvic fractures and their mortality between two different distinct eras of an advanced healthcare system. Anonymized consecutive patient records submitted to TARN UK between 2002 and 2017 by NHS England hospitals were analyzed. Records of patients without a pelvic fracture, or with isolated pelvic fractures (no other serious injury with abbreviated injury scale AIS >2) were excluded. All patients with known outcomes were included and were divided into 2 distinct periods (pre-RTN era: between January 2002 and March 2008 (control group); and RTN era April 2013 to June 2017 (study group)). Data from the transition period from April 2008 to March 2013 were excluded to minimize the effect of variations between the developing networks and MTCs during that era. Overall, the study group included 10,641 patients, whereas the control group was 3152 patients, with a median age of 52.4 and 35.1 years and an ISS of 24 and 27 respectively. A systolic blood pressure below 90mmHg was observed in 7.2% of patients in the study group and 10.4% in the control group. A significant increase of the median time to death (from 8hrs to 188hrs) was observed between the two eras. The cumulative mortality of severely injured patients with pelvic fractures decreased significantly from 17.8% to 12.4% (p<0.0001). The recorded improvement of survivorship in the subgroup of severely injured patients with a pelvic fracture (32% lower in the post-RTN than in the pre-RTN period: OR 1.32  (95% CI 1.21 - 1.44), following the first 5 years of established regional trauma networks in NHS England, is encouraging, and should be attributed to a wide range of factors that translate to all levels of trauma care.

Association between major trauma centre care and outcomes of adult patients injured by low falls in England and Wales

BACKGROUND

Disability and death due to low falls is increasing worldwide and disproportionately affects older adults. Current trauma systems were not designed to suit the needs of these patients. This study assessed the association between major trauma centre (MTC) care and outcomes in adult patients injured by low falls.

METHODS

Data were obtained from the Trauma Audit and Research Network on adult patients injured by falls from <2 m between 2017 and 2019 in England and Wales. 30-day survival, length of hospital stay and discharge destination were compared between MTCs and trauma units or local emergency hospitals (TU/LEHs) using an adjusted multiple logistic regression model.

RESULTS

127 334 patients were included, of whom 27.6% attended an MTC. The median age was 79.4 years (IQR 64.5-87.2 years), and 74.2% of patients were aged >65 years. MTC care was not associated with improved 30-day survival (adjusted OR (AOR) 0.91, 95% CI 0.87 to 0.96, p<0.001). Transferred patients had a significant impact on the results. After excluding transferred patients, MTC care was associated with greater odds of 30-day survival (AOR 1.056, 95% CI 1.001 to 1.113, p=0.044). MTC care was also associated with greater odds of 30-day survival in the most severely injured patients (AOR 1.126, 95% CI 1.04 to 1.22, p=0.002), but not in patients aged >65 years (AOR 1.038, 95% CI 0.982 to 1.097, p=0.184).

CONCLUSION

MTC care was not associated with improved survival compared with TU/LEH care in the whole cohort. Patients who were transferred had a significant impact on the results. In patients who are not transferred, MTC care is associated with greater odds of 30-day survival in the whole cohort and in the most severely injured patients. Future research must determine the optimum means of identifying patients in need of higher-level care, the components of care which improve patient outcomes, develop patient-focused outcomes which reflect the characteristics and priorities of contemporary trauma patients, and investigate the need for transfer in specific subgroups of patients.

Paediatric Major Trauma: A Retrospective Observational Comparison of Mortality in Prehospital Bypass and Secondary Transfer in the East of England

Background More than half of seriously injured children are not initially treated at a major trauma centre (MTC). Children may be transported by private vehicle to a trauma unit (TU). Children may also be transported by emergency medical services (EMS) to the nearest TU with approximately one in five of these undergoing secondary transfer to an MTC. Most trauma networks permit TU bypass to an MTC. However, the evidence on outcomes between transfer and bypass is limited. This study aimed to evaluate the use of the trauma network by comparing outcomes between paediatric major trauma patients by the method of presentation. Methods In this retrospective observational study, a consecutive sample of paediatric (<16 years old) major trauma patients transported to the regional MTC (Cambridge University Hospitals NHS Foundation Trust (CUH)) between 1st January 2015 and 31st December 2020 was included. Patients were excluded if they arrived at the MTC >24 hours post-injury or were transported to the MTC as the nearest hospital. Patients were divided into four groups: self-presented to MTC, MTC as nearest hospital, bypass and secondary transfer. Results A total of 315 patients (28 'self-presented', 55 'nearest', 58 'bypass' and 174 'secondary transfers') were included. The median age was 9.4 [3.7-13.6] years, and n=209 (66.3%) were male. The median Injury Severity Score (ISS) was 16.0 [9.0-25.0] and n=190 (60.3%) had an ISS >15. There was no difference in 30-day mortality between the 'bypass' and 'secondary transfer' groups. There was a significantly longer hospital and intensive care unit length of stay (LOS) in the bypass group compared to other groups, both p<0.001. The median time to definitive care was five hours greater in the secondary transfer group compared to 'bypass' (bypass 117.6 minutes [100.8-136.6], secondary transfer 418.8 minutes [315.6-529.8]). Conclusion There was no significant difference in 30-day mortality of paediatric major trauma patients who underwent secondary transfer compared to those transported directly from the scene to the MTC, despite significant time delays in reaching definitive care.

Towards exploring current challenges and future opportunities relating to the prehospital triage of patients with traumatic brain injury: a mixed-methods study protocol

INTRODUCTION

Traumatic brain injury (TBI) is a major global health burden that results in disability and loss of health. Identifying those patients who require specialist neuroscience care can be challenging due to the low accuracy of existing prehospital trauma triage tools. Despite the widespread use of decision aids to 'rule out' TBI in hospitals, they are not widely used in the prehospital environment. We aim to provide a snapshot of current prehospital practices in the UK, and to explore facilitators and challenges that may be encountered when adopting new tools for decision support.

METHODS AND ANALYSIS

A mixed-methods study will be conducted using a convergent design approach. In the first phase, we will conduct a national survey of current practice in which every participating ambulance service in the UK will receive an online questionnaire, and only one response is required. In the second phase, semistructured interviews will be conducted to explore the perceptions of ambulance service personnel regarding the implementation of new triage methods that may enhance triage decisions. The survey questions and the interview topic guide were piloted and externally reviewed. Quantitative data will be summarised using descriptive statistics; qualitative data will be analysed thematically.

ETHICS AND DISSEMINATION

This study has been approved by the Health Research Authority (REC reference 22/HRA/2035). Our findings may inform the design of future care pathways and research as well as identify challenges and opportunities for future development of prehospital triage tools for patients with suspected TBI. Our findings will be published in peer-reviewed journals, relevant national and international conferences, and will be included in a PhD thesis.

The value of performing cerebrovascular CT angiography in major trauma patients: a 5-year retrospective review

AIM

To assess whether routine cerebrovascular imaging is required in all major trauma (MT) patients.

MATERIALS AND METHODS

All MT patients with cerebrovascular imaging between January 2015 and December 2020 were included in the study. Data were collated regarding the type of indication for computed tomography (CT) angiography imaging, time interval from the initial trauma, relevant trauma diagnoses on initial trauma imaging, and CT angiography. Findings, such as aneurysms, vascular malformations, luminal thrombus, venous sinus thrombosis, or vascular injury, were collated. Subsequent treatment with anti-coagulants/anti-platelets or surgical/radiological intervention was noted. Follow-up imaging was assessed for residual injury or complications.

RESULTS

Two hundred and fifty of the 6,251 MT patients underwent dedicated cerebrovascular imaging and were included in the study. Of these 41 (16.4%) had cervical artery or venous sinus injury. Further positive vascular findings were identified in 25/250 patients who presented with an incidental stroke or a vascular abnormality and were mislabelled as MT patients at presentation. One patient with a carotid injury subsequently died following a large infarction. Another patient with vertebral artery injury suffered a non-lethal stroke. No patients underwent surgery or intervention.

CONCLUSION

The present study showed that the overall incidence of detected blunt cerebrovascular injuries was very low (0.6%) and even lower for symptomatic vascular injury (0.03%). Routine cerebrovascular imaging is not recommended in all MT trauma patients, but instead, a continued case-by-case basis should be considered.

Rehabilitation outcomes based on service provision and geographical location for patients with multiple trauma: A mixed-method systematic review

INTRODUCTION

Previous research has highlighted the benefit of regionalised trauma networks in relation to decreased mortality. However, patients who now survive increasingly complex injuries continue to navigate the challenges of recovery, often with a poor view of their experiences of the rehabilitation journey. Geographical location, unclear rehabilitation outcomes and limited access to the provision of care are increasingly noted by patients as negatively influencing their view of recovery.

STUDY DESIGN

This mixed-methods systematic review included research that addresses the impact of service provision and geographical location of rehabilitation services for multiple trauma patients. The primary aim of the study was to analyse functional independence measure (FIM) outcomes. The secondary aim of the research was to examine the rehabilitation needs and experiences of multiple trauma patients by identifying themes around the barriers and challenges to rehabilitation provision. Finally, the study aimed to contribute to the gap in literature around the rehabilitation patient experience.

METHODS

An electronic search of seven databases was undertaken against pre-determined inclusion/exclusion criteria. The Mixed Methods Appraisal Tool was utilised for quality appraisal. Following data extraction, both quantitative and qualitative analysis methods were utilised. In total, 17,700 studies were identified and screened against the inclusion/exclusion criteria. Eleven studies met the inclusion criteria (five quantitative, four qualitative, two mixed method).

RESULTS

FIM scores showed no significant difference in all studies after long-term follow-up. However, statistically significantly less FIM improvement was noted in those with unmet needs. Patients with physiotherapist assessed unmet rehabilitation needs were statistically less likely to improve than patients whose needs were reportedly met. In contrast, there was a differing opinion regarding the success of structured therapy input, communication and coordination, long-term support and planning for home. Common qualitative themes revealed lack of rehabilitation post-discharge, often with long waiting times.

CONCLUSION

Stronger communication pathways and coordination within a trauma network, particularly when repatriating outside of a network catchment area is recommended. This review has exposed the many rehabilitation variations and complexities a patient may experience following trauma. Furthermore, this highlights the importance of arming clinicians with the tools and expertise to improve patient outcomes.

Improvements over time for patients following liver trauma: A 17-year observational study

Background

Centralisation of trauma care has been shown to be associated with improved patient outcomes. The establishment of Major Trauma Centres (MTC) and networks in England in 2012 allowed for centralisation of trauma services and specialties including hepatobiliary surgery. We aimed to investigate the outcomes for patients with hepatic injury over the last 17 years at a large MTC in England in relation to the MTC status of the centre.

Methods

All patients who sustained liver trauma between 2005 and 2022 were identified using the Trauma Audit and Research Network database for a single MTC in the East Midlands. Mortality and complications were compared between patients before and after establishment of MTC status. Multivariable logistic regression models were used to determine the odds ratio (OR) and 95% confidence interval (95% CI) for complications according to MTC status, accounting for the potentially confounding variables of age, sex, severity of injuries and comorbidities for all patients, and the subgroup with severe liver trauma (AAST Grade IV and V).

Results

There were 600 patients; the median age was 33 (IQR 22-52) years and 406/600 (68%) were male. There were no significant differences in 90-day mortality or length of stay between the pre- and post-MTC patients. Multivariable logistic regression models showed both lower overall complications [OR 0.24 (95% CI 0.14, 0.39); p < 0.001] and lower liver-specific complications [OR 0.21 (95% CI 0.11, 0.39); p < 0.001] in the post-MTC period. This was also the case in the severe liver injury subgroup (p = 0.008 and p = 0.002 respectively).

Conclusions

Outcomes for liver trauma were superior in the post-MTC period even when adjusted for patient and injury characteristics. This was the case even though patients in this period were older with more comorbidities. These data support the centralisation of trauma services for those with liver injuries.

Variation in timely surgery for severe open tibial fractures by time and place of presentation in England from 2012 to 2019 : a cohort study using data collected nationally by the Trauma Audit and Research Network

AIMS

Several studies have reported that patients presenting during the evening or weekend have poorer quality healthcare. Our objective was to examine how timely surgery for patients with severe open tibial fracture varies by day and time of presentation and by type of hospital. This cohort study included patients with severe open tibial fractures from the Trauma Audit and Research Network (TARN).

METHODS

Provision of prompt surgery (debridement within 12 hours and soft-tissue coverage in 72 hours) was examined, using multivariate logistic regression to derive adjusted risk ratios (RRs). Time was categorized into three eight-hour intervals for each day of the week. The models were adjusted for treatment in a major trauma centre (MTC), sex, age, year of presentation, injury severity score, injury mechanism, and number of operations each patient received.

RESULTS

We studied 8,258 patients from 175 hospitals. Patients presenting during the day (08:00 to 15:59; risk ratio (RR) 1.11, 95% confidence interval (CI) 1.02 to 1.20) were more likely to receive debridement within 12 hours, and patients presenting at night (16:00 to 23:59; RR 0.56, 95% CI 0.51 to 0.62) were less likely to achieve the target; triage to a MTC had no effect. Day of presentation was associated with soft-tissue coverage within 72 hours; patients presenting on a Thursday or Friday being less likely to receive this surgery within 72 hours (Thursday RR 0.88, 95% CI 0.81 to 0.97; Friday RR 0.89, 95% CI 0.81 to 0.98), and the standard less likely to be achieved for those treated in 'non-MTC' hospitals (RR 0.76, 95% CI 0.70 to 0.82).

CONCLUSION

Variations in care were observed for timely surgery for severe open tibial fractures with debridement surgery affected by time of presentation and soft-tissue coverage affected by day of presentation and type of hospital. The variation is unwarranted and highlights that there are opportunities to substantially improve the delivery and quality of care for patients with severe open tibial fracture.Cite this article: Bone Jt Open 2022;3(12):941-952.

Priorities for returning to work after traumatic injury: A public and professional involvement study

Introduction

Following traumatic injury, occupational therapists (OTs) are pivotal in supporting people to return-to-work (RTW) and regain independence. Aim: to identify priorities for RTW after traumatic injury and highlight barriers hindering the process.

Method

We recruited 17 participants with direct (i.e. trauma survivor [n = 11]; OT trauma survivor [n = 2]) or indirect (i.e. OT [n = 4]) experience of returning to work following traumatic injury. Online consultations, lasting 60 min, were guided by a semi-structured script ensuring relevant topics were covered. An inductive approach was used for coding themes using thematic analysis.

Findings

Sense of purpose, identity and social interaction were greater priorities for RTW, than financial stability. Major barriers were: pain and fatigue; adapting to physical changes; impacts on mental health; and lack of support (healthcare and the workplace). Participants (public and healthcare professionals) reported a lack of vocational rehabilitation in supporting trauma survivors RTW, but advocated occupational therapy for psychological recovery; purposeful engagement in occupations; and community support.

Conclusion

Restoring an individual's self-identity and social connections, whilst helping control pain and fatigue, should be prioritised when planning occupational therapy for those returning to work after traumatic injury. This study was limited to 'returners', but can inform occupational therapy interventions for RTW.

Validation of the adapted clavien dindo in trauma (ACDiT) scale to grade management related complications at a level I trauma center

Objectives

Complications during trauma management are the main factor responsible for the overall increase in treatment cost. There are very few grading systems to measure the burden of complications in trauma patients. A prospective study was conducted using the Adapted Clavien Dindo in Trauma (ACDiT) scale, with the primary aim of validating it at our center. As a secondary aim, it was also wanted to measure the mortality burden among our admitted patients.

Material and Methods

The study was conducted at a dedicated trauma center. All patients with acute injuries, who were admitted, were included. An initial treatment plan was made within 24 hours of admission. Any deviation from this was recorded and graded according to the ACDiT. The grading was correlated with hospital-free days and ICU-free days within 30 days.

Results

A total of 505 patients were included in this study, with a mean age of 31 years. The most common mechanism of injury was road traffic injury, with a median ISS and NISS of 13 and 14, respectively. Two hundred and forty-eight out of 505 patients had some grade of complication as determined by the ACDiT scale. Hospital-free days (13.5 vs. 25; p <0.001) were significantly lower in patients with complications than those without complications, and so were ICU-free days (29 vs. 30; p <0.001). Significant differences were also observed when comparing mean hospital free and ICU free days across various ACDiT grades. Overall mortality of the population was 8.3 %, the majority of whom were hypotensive on arrival and required ICU care.

Conclusion

We successfully validated the ACDiT scale at our center. We recommend using this scale to objectively measure in-hospital complications and improve trauma management quality. ACDiT scale should be one of the data points in any trauma database/registry.

Motorcycle-related trauma in Ireland

Introduction

Motorcyclists are over-represented in collision statistics in Ireland. There is a lack of descriptive studies assessing the impact and injury pattern of this trauma cohort. This study examines this trauma subset using data collected by the Major Trauma Audit (MTA) by the National Office of Clinical Audit (NOCA) to identify patient demographics, injury mechanism and type, treatments received, and outcomes.

Methods

All motorcycle-related trauma cases recorded on the MTA, NOCA in Ireland for the period 2014 to 2019 were gathered and analysed.

Results

There were 704 cases identified; 94% of cases were male. The median (interquartile range (IQR)) age was 38.2 (26.7–49.7). There were 6.4% ( n = 45) aged 0–18 years, 88.2% ( n = 621) aged 18–64 and 5.4% ( n = 38) greater than 65 years. The median injury severity score (ISS) overall of this trauma cohort was 13 (IQR 9–24) but 306 patients (43.5%) had an ISS > 15. The most severe injury body region with 35.4% ( n = 249) was the limbs. Most patients arrived during the summer months with Sunday the highest day of attendance ( n = 181, 25.7%). May to August were the months with the most attendance ( n = 366, 52%). Most patients were discharged home ( n = 372, 52.8%) and 43.8% ( n = 308) required transfer to at least one other hospital for definitive care. There were 19 patients (2.7%) who died after arrival to hospital.

Conclusion

Motorcycle trauma predominantly affects a young male population with moderate severity injury characteristics. A significant proportion of patients present at weekends during the summer months, likely the result of recreational riding. A large cohort of patients requires transfer for definitive care, which has significant implications for trauma care pathways. National policies to enforce safety measures and public awareness for recreational motorcycle use may improve traffic safety and ultimately population health.

A retrospective review of patients who sustained traumatic brain injury in Ireland 2014-2019

INTRODUCTION

Traumatic brain injury (TBI) is the most significant cause of death and disability resulting from major trauma. The aim of this study is to describe the demographics of TBI patients, the current pathways of care and outcomes in the Republic of Ireland from 2014 to 2019.

METHODS

We performed a retrospective review of all TBI patients meeting inclusion criteria in Ireland's Major Trauma Audit (MTA) from 2014 to 2019. Severe TBI was defined as an abbreviated injury scale (AIS) ≥3 and GCS ≤8.

RESULTS

During the study period, 30,891 patients sustained major trauma meeting inclusion criteria for MTA, of which 7,393 (23.9%) patients met the inclusion criteria for TBI; 1,025 (13.9%) were classified as severe. The median age was 60.6 years (IQR 36.9-78.0), 54.3 years (32.8-73.4) for males and 71.7 years (50.0-83.0) for females (p<0.001). Of patients with severe TBI, 185 (18.0%) were brought direct to a neurosurgical centre, 389 (37.9%) were transferred to a neurosurgical centre and 321 (31.3%) had a neurosurgical intervention performed. In patients sustaining severe TBI, older patients (Adjusted OR, 0.96,95% CI 0.95-0.97) and patients requiring another surgery (OR 0.31, 95%CI 0.18-0.53) were less likely to be secondarily transferred to a neurosurgical centre. There were 47 (4.6%) patients with severe TBI discharged to rehabilitation. The 30-day mortality in Ireland was 11.6% in all TBI patients and 45.5% in severe TBI patients. Older patients and patients with higher ISS had a higher chance of death. Male patients, patients treated in neurosurgical centre, patients who had neurosurgery or non-neurosurgical surgery had a higher chance of survival.

CONCLUSION

This population-based study bench marks the 'as is' for patients with TBI in Ireland. We found that presently in Ireland, the mortality rate from severe TBI appears to be higher than that reported in international literature, and only a minority of severe TBI patients are brought directly from the incident to a neurosurgical centre. The new major trauma system should focus on providing effective and efficient access to neurosurgical, neuro-critical and neuro-rehabilitative care for patients who sustain TBI.

Innovations in orthopaedic trauma: Top advancements of the past two decades and predictions for the next two

The first Trauma and Orthopaedic unit dates back to 1780, originally dedicated to the treatment of children's deformities. The specialty has subsequently become multifaceted, with a plethora of subspecialty areas of which orthopaedic trauma is the most commonly practiced. Recently there has been a significant demand for an evidence base with more than 130,000 of the 162,000 publications in the last century occurring within the past 20 years. This narrative review will summarise some of the more landmark changes within orthopaedic trauma that have been made within the past 20 years, whilst also attempting to predict where the specialty will continue to develop as we move forward.

Traumatic brain injury: progress and challenges in prevention, clinical care, and research

Traumatic brain injury (TBI) has the highest incidence of all common neurological disorders, and poses a substantial public health burden. TBI is increasingly documented not only as an acute condition but also as a chronic disease with long-term consequences, including an increased risk of late-onset neurodegeneration. The first Lancet Neurology Commission on TBI, published in 2017, called for a concerted effort to tackle the global health problem posed by TBI. Since then, funding agencies have supported research both in high-income countries (HICs) and in low-income and middle-income countries (LMICs). In November 2020, the World Health Assembly, the decision-making body of WHO, passed resolution WHA73.10 for global actions on epilepsy and other neurological disorders, and WHO launched the Decade for Action on Road Safety plan in 2021. New knowledge has been generated by large observational studies, including those conducted under the umbrella of the International Traumatic Brain Injury Research (InTBIR) initiative, established as a collaboration of funding agencies in 2011. InTBIR has also provided a huge stimulus to collaborative research in TBI and has facilitated participation of global partners. The return on investment has been high, but many needs of patients with TBI remain unaddressed. This update to the 2017 Commission presents advances and discusses persisting and new challenges in prevention, clinical care, and research.

In LMICs, the occurrence of TBI is driven by road traffic incidents, often involving vulnerable road users such as motorcyclists and pedestrians. In HICs, most TBI is caused by falls, particularly in older people (aged ≥65 years), who often have comorbidities. Risk factors such as frailty and alcohol misuse provide opportunities for targeted prevention actions. Little evidence exists to inform treatment of older patients, who have been commonly excluded from past clinical trials—consequently, appropriate evidence is urgently required. Although increasing age is associated with worse outcomes from TBI, age should not dictate limitations in therapy. However, patients injured by low-energy falls (who are mostly older people) are about 50% less likely to receive critical care or emergency interventions, compared with those injured by high-energy mechanisms, such as road traffic incidents.

Mild TBI, defined as a Glasgow Coma sum score of 13–15, comprises most of the TBI cases (over 90%) presenting to hospital. Around 50% of adult patients with mild TBI presenting to hospital do not recover to pre-TBI levels of health by 6 months after their injury. Fewer than 10% of patients discharged after presenting to an emergency department for TBI in Europe currently receive follow-up. Structured follow-up after mild TBI should be considered good practice, and urgent research is needed to identify which patients with mild TBI are at risk for incomplete recovery.

The selection of patients for CT is an important triage decision in mild TBI since it allows early identification of lesions that can trigger hospital admission or life-saving surgery. Current decision making for deciding on CT is inefficient, with 90–95% of scanned patients showing no intracranial injury but being subjected to radiation risks. InTBIR studies have shown that measurement of blood-based biomarkers adds value to previously proposed clinical decision rules, holding the potential to improve efficiency while reducing radiation exposure. Increased concentrations of biomarkers in the blood of patients with a normal presentation CT scan suggest structural brain damage, which is seen on MR scanning in up to 30% of patients with mild TBI. Advanced MRI, including diffusion tensor imaging and volumetric analyses, can identify additional injuries not detectable by visual inspection of standard clinical MR images. Thus, the absence of CT abnormalities does not exclude structural damage—an observation relevant to litigation procedures, to management of mild TBI, and when CT scans are insufficient to explain the severity of the clinical condition.

Although blood-based protein biomarkers have been shown to have important roles in the evaluation of TBI, most available assays are for research use only. To date, there is only one vendor of such assays with regulatory clearance in Europe and the USA with an indication to rule out the need for CT imaging for patients with suspected TBI. Regulatory clearance is provided for a combination of biomarkers, although evidence is accumulating that a single biomarker can perform as well as a combination. Additional biomarkers and more clinical-use platforms are on the horizon, but cross-platform harmonisation of results is needed. Health-care efficiency would benefit from diversity in providers.

In the intensive care setting, automated analysis of blood pressure and intracranial pressure with calculation of derived parameters can help individualise management of TBI. Interest in the identification of subgroups of patients who might benefit more from some specific therapeutic approaches than others represents a welcome shift towards precision medicine. Comparative-effectiveness research to identify best practice has delivered on expectations for providing evidence in support of best practices, both in adult and paediatric patients with TBI.

Progress has also been made in improving outcome assessment after TBI. Key instruments have been translated into up to 20 languages and linguistically validated, and are now internationally available for clinical and research use. TBI affects multiple domains of functioning, and outcomes are affected by personal characteristics and life-course events, consistent with a multifactorial bio-psycho-socio-ecological model of TBI, as presented in the US National Academies of Sciences, Engineering, and Medicine (NASEM) 2022 report. Multidimensional assessment is desirable and might be best based on measurement of global functional impairment. More work is required to develop and implement recommendations for multidimensional assessment. Prediction of outcome is relevant to patients and their families, and can facilitate the benchmarking of quality of care. InTBIR studies have identified new building blocks (eg, blood biomarkers and quantitative CT analysis) to refine existing prognostic models. Further improvement in prognostication could come from MRI, genetics, and the integration of dynamic changes in patient status after presentation.

Neurotrauma researchers traditionally seek translation of their research findings through publications, clinical guidelines, and industry collaborations. However, to effectively impact clinical care and outcome, interactions are also needed with research funders, regulators, and policy makers, and partnership with patient organisations. Such interactions are increasingly taking place, with exemplars including interactions with the All Party Parliamentary Group on Acquired Brain Injury in the UK, the production of the NASEM report in the USA, and interactions with the US Food and Drug Administration. More interactions should be encouraged, and future discussions with regulators should include debates around consent from patients with acute mental incapacity and data sharing. Data sharing is strongly advocated by funding agencies. From January 2023, the US National Institutes of Health will require upload of research data into public repositories, but the EU requires data controllers to safeguard data security and privacy regulation. The tension between open data-sharing and adherence to privacy regulation could be resolved by cross-dataset analyses on federated platforms, with the data remaining at their original safe location. Tools already exist for conventional statistical analyses on federated platforms, however federated machine learning requires further development. Support for further development of federated platforms, and neuroinformatics more generally, should be a priority.

This update to the 2017 Commission presents new insights and challenges across a range of topics around TBI: epidemiology and prevention (section 1 ); system of care (section 2 ); clinical management (section 3 ); characterisation of TBI (section 4 ); outcome assessment (section 5 ); prognosis (Section 6 ); and new directions for acquiring and implementing evidence (section 7 ). Table 1 summarises key messages from this Commission and proposes recommendations for the way forward to advance research and clinical management of TBI.

Patient reported outcomes after definitive open tibial fracture management

AIMS

Open tibial fractures are often life-changing injuries and patient outcomes remain poor despite the introduction of national management guidelines. The longer-term impact to the patient can be considerable but this is often overlooked in the literature. This study aims to establish the functional, physical, and psychosocial impact of sustaining an open tibial fracture.

METHODS

We reviewed 69 consecutive Gustilo-Anderson grade IIIB and IIIC open tibial fractures that presented to our Major Trauma Centre (MTC) between September 2012 and April 2018. Each participant was interviewed and sent patient-reported outcome questionnaires, a minimum of 12 months following injury. Our primary outcome was the Lower Extremity Functional Scale (LEFS). Secondary outcomes included the Short-Form 36 Healthy Survey (SF-36), Sickness Impact Profile 128 (SIP) and return to occupation. Subgroups were analysed according to age, Injury Severity Score (ISS) and limb amputation.

RESULTS

The mean follow up was 43 months. 96% were grade IIIB and 4% grade IIIC. The response rate for our study was 72%. The mean LEFS was 42 (IQR 21.5-58.5). All total and sub-domain scores within both the SF-36 and SIP questionnaires were reduced when compared to normative population data. Only 48% of patients returned to full time employment. Subgroup analysis revealed significantly reduced LEFS, SIP and SF-36 subdomain scores for those with a presenting ISS >14 and those undergoing limb amputation.

CONCLUSION

Patients are at significant risk of longer-term functional, physical and psychosocial harm after suffering an open tibial fracture. Those sustaining major polytrauma or amputation demonstrated to have the greatest risk of poor outcome. Early identification of these individuals likely to suffer most from their injury would help direct appropriate resources to those with greatest need at the earliest opportunity.

Management of penetrating chest trauma in the context of major trauma networks

Major trauma networks reduce mortality in critically injured patients. Trauma patients should be appropriately triaged straight from the scene of injury, avoiding secondary transfer from a trauma unit. Selection criteria in regionally agreed triage tools are designed to identify which patients should be taken directly to the major trauma centre. Patients with life-threatening injuries still arrive at 'trauma units' in circumstances such as self-presentation, under triage, physiological instability or long journey time to the major trauma centre. This article presents a theoretical case of a haemodynamically unstable patient with penetrating injuries, and discusses the management of chest trauma, including diagnosis of life-threatening injuries, resuscitation strategies and definitive surgical management. Secondary transfer to the major trauma centre should be considered after instituting the minimal life-saving interventions. What constitutes a life-saving intervention requires an individual dynamic risk assessment and an understanding of major trauma networks.

The Open-Fracture Patient Evaluation Nationwide (OPEN) study : epidemiology of open fracture care in the UK

AIMS

Understanding of open fracture management is skewed due to reliance on small-number lower limb, specialist unit reports and large, unfocused registry data collections. To address this, we carried out the Open Fracture Patient Evaluation Nationwide (OPEN) study, and report the demographic details and the initial steps of care for patients admitted with open fractures in the UK.

METHODS

Any patient admitted to hospital with an open fracture between 1 June 2021 and 30 September 2021 was included, excluding phalanges and isolated hand injuries. Institutional information governance approval was obtained at the lead site and all data entered using Research Electronic Data Capture. Demographic details, injury, fracture classification, and patient dispersal were detailed.

RESULTS

In total, 1,175 patients (median age 47 years (interquartile range (IQR) 29 to 65), 61.0% male (n = 717)) were admitted across 51 sites. A total of 546 patients (47.1%) were employed, 5.4% (n = 63) were diabetic, and 28.8% (n = 335) were smokers. In total, 29.0% of patients (n = 341) had more than one injury and 4.8% (n = 56) had two or more open fractures, while 51.3% of fractures (n = 637) occurred in the lower leg. Fractures sustained in vehicle incidents and collisions are common (38.8%; n = 455) and typically seen in younger patients. A simple fall (35.0%; n = 410) is common in older people. Overall, 69.8% (n = 786) of patients were admitted directly to an orthoplastic centre, 23.0% (n = 259) were transferred to an orthoplastic centre after initial management elsewhere, and 7.2% were managed outwith specialist units (n = 81).

CONCLUSION

This study describes the epidemiology of open fractures in the UK. For a decade, orthopaedic surgeons have been practicing in a guideline-driven, network system without understanding the patient features, injury characteristics, or dispersal processes of the wider population. This work will inform care pathways as the UK looks to the future of trauma networks and guidelines, and how to optimize care for patients with open fractures.Cite this article: Bone Jt Open 2022;3(10):746-752.

Challenges and opportunities in the care of chronic subdural haematoma: perspectives from a multi-disciplinary working group on the need for change

INTRODUCTION

A chronic subdural haematoma (cSDH) is a collection of altered blood products between the dura and brain resulting in a slowly evolving neurological deficit. It is increasingly common and, in high income countries, affects an older, multimorbid population. With changing demographics improving the care of this cohort is of increasing importance.

METHODS

We convened a cross-disciplinary working group (the 'Improving Care in Elderly Neurosurgery Initiative') in October 2020. This comprised experts in neurosurgical care and a range of perioperative stakeholders. An Implementation Science framework was used to structure discussions around the challenges of cSDH care within the United Kingdom. The outcomes of these discussions were recorded and summarised, before being circulated to all attendees for comment and refinement.

RESULTS

The working group identified four key requirements for improving cSDH care: (1) data, audit, and natural history; (2) evidence-based guidelines and pathways; (3) shared decision-making; and (4) an overarching quality improvement strategy. Frequent transfers between care providers were identified as impacting on both perioperative care and presenting a barrier to effective data collection and teamworking. Improvement initiatives must be cognizant of the complex, system-wide nature of the problem, and may require a combination of targeted trials at points of clinical equipoise (such as anesthetic technique or anticoagulant management), evidence-based guideline development, and a cycle of knowledge acquisition and implementation.

CONCLUSION

The care of cSDH is a growing clinical problem. Lessons may be learned from the standardised pathways of care such as those as used in hip fracture and stroke. A defined care pathway for cSDH, encompassing perioperative care and rehabilitation, could plausibly improve patient outcomes but work remains to tailor such a pathway to cSDH care. The development of such a pathway at a national level should be a priority, and the focus of future work.

Trauma provision in South-West Nigeria: Epidemiology, challenges and priorities

•

This article highlights the epidemiology of trauma and common challenges of trauma provision in the region.

•

It elucidates the urgent need to improve trauma care in Nigeria and other African countries.

•

Furthermore, it advocates for the development of a regionalised trauma system and centralised trauma registry amongst others.

Trauma is a crucial public health problem that has been overlooked by developing countries including Nigeria. It has led to a worsening trauma trend as recent data suggests. The South-West Region of Nigeria remains one of the regions with the most injury prevalence. Since the introduction of the trauma system over half a century ago, regionalised trauma systems have become increasingly effective in changing the dynamics of trauma care and outcomes. However, similar to most developing countries trauma system is yet to be established in any region in Nigeria. This is also met by a lack of a centralised trauma registry, poor implementation of primary prevention practices, an informal prehospital care system, and poorly organised in-hospital care for trauma victims. Reversing these challenges could be a propelling force to the revolution of trauma provision in the region and extension to the nation, Africa, and other developing countries. Nevertheless, the stakeholders such as the government, legislature, Non-Governmental-Organisations, law-enforcement agencies, healthcare institutions, trauma experts, and the public have a huge role.

Multi-Omic Admission-Based Prognostic Biomarkers Identified by Machine Learning Algorithms Predict Patient Recovery and 30-Day Survival in Trauma Patients

Admission-based circulating biomarkers for the prediction of outcomes in trauma patients could be useful for clinical decision support. It is unknown which molecular classes of biomolecules can contribute biomarkers to predictive modeling. Here, we analyzed a large multi-omic database of over 8500 markers (proteomics, metabolomics, and lipidomics) to identify prognostic biomarkers in the circulating compartment for adverse outcomes, including mortality and slow recovery, in severely injured trauma patients. Admission plasma samples from patients (n = 129) enrolled in the Prehospital Air Medical Plasma (PAMPer) trial were analyzed using mass spectrometry (metabolomics and lipidomics) and aptamer-based (proteomics) assays. Biomarkers were selected via Least Absolute Shrinkage and Selection Operator (LASSO) regression modeling and machine learning analysis. A combination of five proteins from the proteomic layer was best at discriminating resolvers from non-resolvers from critical illness with an Area Under the Receiver Operating Characteristic curve (AUC) of 0.74, while 26 multi-omic features predicted 30-day survival with an AUC of 0.77. Patients with traumatic brain injury as part of their injury complex had a unique subset of features that predicted 30-day survival. Our findings indicate that multi-omic analyses can identify novel admission-based prognostic biomarkers for outcomes in trauma patients. Unique biomarker discovery also has the potential to provide biologic insights.

Epidemiology of pelvic and acetabular fractures across 12-mo at a level-1 trauma centre

BACKGROUND

Despite motor-vehicle safety advancements and increasingly rigorous workplace safety regulations, trauma/suicide remains the leading cause of death under the age of 45 in the United Kingdom. To promote centralisation of care and optimisation of major trauma outcomes, in 2012 the National Health Service introduced the Trauma Network System. To our knowledge, this is the first study to analyse the epidemiology of pelvic and acetabular trauma over a one-year period at a level-1 trauma centre in the United Kingdom, since nationwide introduction of the Trauma Network System.

AIM

To characterize the epidemiology of high-energy pelvic and acetabular fractures over a one-year period at a level-1 trauma centre, and explore both resources required to care for these patients and opportunities for future research and injury prevention initiatives.

METHODS

227 consecutive patients at a level-1 trauma centre with pelvic and acetabular fractures were analysed between December 2017-December 2018. Paediatric patients (< 18 years) and fragility fractures were excluded, leaving 175 patients for inclusion in the study. Statistical analysis was performed using Fisher’s exact test for categorical variables.

RESULTS

72% of pelvic and acetabular fractures occurred in male patients at a median age of 45 years. 15% were the result of a suicide attempt. 48% of patients required pelvic or acetabular surgery, with 38% undergoing further surgery for additional orthopaedic injuries. 43% of patients were admitted to intensive care. The median inpatient stay was 13 days, and the 30- day mortality was 5%. Pelvic ring trauma was more commonly associated with abdominal injury (P = 0.01) and spine fractures (P < 0.001) than acetabular fractures. Vertical shear pelvic ring fractures were associated with falls (P = 0.03) while lateral compression fractures were associated with road traffic accidents (P = 0.01).

CONCLUSION

High energy pelvic and acetabular fractures are associated with concomitant orthopaedic fractures (most commonly spine and lower limb), intensive care admission and prolonged inpatient stays. Most pelvic ring injuries secondary to road traffic accidents are lateral compression type, demonstrating the need for future research to drive advancements in lateral impact vehicle safety along with mental health surveillance for those deemed to be potential suicide risks.

A national study of 23 major trauma centres to investigate the effect of a geriatrician assessment on clinical outcomes in older people admitted with serious injury in England (FiTR 2): a multicentre observational cohort study

BACKGROUND

Older people are at the greatest risk of poor outcomes after serious injury. Evidence is limited for the benefit of assessment by a geriatrician in trauma care. We aimed to determine the effect of geriatrician assessment on clinical outcomes for older people admitted to hospital with serious injury.

METHODS

In this multicentre observational study (FiTR 2), we extracted prospectively collected data on older people (aged ≥65 years) admitted to the 23 major trauma centres in England over a 2·5 year period from the Trauma Audit and Research Network (TARN) database. We examined the effect of a geriatrician assessment within 72 h of admission on the primary outcome of inpatient mortality in older people admitted to hospital with serious injury, with patients censored at discharge. We analysed data using a multi-level Cox regression model and estimated adjusted hazard ratios (aHRs).

FINDINGS

Between March 31, 2019, and Oct 31, 2021, 193 156 patients had records held by TARN, of whom 35 490 were included in these analyses. Median age was 81·4 years (IQR 74·1-87·6), 19 468 (54·9%) were female, and 16 022 (45·1%) were male. 28 208 (79·5%) patients had experienced a fall from less than 2 m. 16 504 (46·5%) people received a geriatrician assessment. 4419 (12·5%) patients died during hospital stay, with a median time from admission to death of 6 days (IQR 2-14). Of those who died, 1660 (37·6%) had received a geriatrician assessment and 2759 (62·4%) had not (aHR 0·43 [95% CI 0·40-0·46]; p<0·0001).

INTERPRETATION

Geriatrician assessment was associated with a reduced risk of death for seriously injured older people. These data support routine provision of geriatrician assessment in trauma care. Future research should explore the key components of a geriatrician assessment paired with a health economic evaluation.

FUNDING

None.

A national study of 23 major trauma centres to investigate the effect of frailty on clinical outcomes in older people admitted with serious injury in England (FiTR 1): a multicentre observational study

BACKGROUND

Older people are the largest group admitted to hospital with serious injuries. Many older people are living with frailty, a risk factor for poor recovery. We aimed to examine the effect of preinjury frailty on outcomes.

METHODS

In this multicentre observational study (FiTR 1), we extracted prospectively collected data from all 23 adult major trauma centres in England on older people (aged ≥65 years) admitted with serious injuries over a 2·5 year period from the Trauma Audit and Research Network (TARN) database. Geriatricians assessed the preinjury Clinical Frailty Scale (CFS), a 9-point scale of fitness and frailty, with a score of 1 indicating a patient is very fit and a score of 9 indicating they are terminally ill. The primary outcome was inpatient mortality, with patients censored at hospital discharge. We used a multi-level Cox regression model fitted with adjusted hazards ratios (aHRs) to assess the association between CFS and mortality, with CFS scores being grouped as follows: a score of 1-2 indicated patients were fit; a score of 3 indicated patients were managing well; and a score of 4-8 indicated patients were living with frailty (4 being very mild, 5 being mild, 6 being moderate, and 7-8 being severe).

FINDINGS

Between March 31, 2019, and Oct 31, 2021, 193 156 patients had records were held by TARN, of whom 16 504 had eligible records. Median age was 81·9 years (IQR 74·7-88·0), 9200 (55·7%) were women, and 7304 (44·3%) were men. Of 16 438 patients with a CFS score of 1-8, 11 114 (67·6%) were living with frailty (CFS of 4-8). 1660 (10·1%) patients died during their hospital stay, with a median time from admission to death of 9 days (IQR 4-18). Compared in patients with a CFS score of 1-2, risk of inpatient death was increased in those managing well (CFS score of 3; aHR 1·82 [95% CI 1·39-2·40]), living with very mild frailty (CFS score of 4: 1·99 [1·51-2·62]), living with mild frailty (CFS score of 5: 2·61 [1·99-3·43]), living with moderate frailty (CFS score of 6: 2·97 [2·26-3·90]), and living with severe frailty (CFS score of 7-8: 4·03 [3·04-5·34]).

INTERPRETATION

Our findings support inclusion of the CFS in trauma pathways to aid patient management. Additionally, people who exercise regularly (CFS of 1-2) have better outcomes than those with lower activity levels (CFS of ≥3), supporting exercise as an intervention to improve trauma outcomes.

FUNDING

None.
