The effect of population density on outcomes of major trauma patients in Ireland

BackgroundTime-sensitive emergencies in areas of low population density have statistically poorer outcomes. This includes incidents of major trauma. This study assesses the effect that population density at a receiving hospital of a major trauma patient has on survival. MethodsPatients meeting Trauma Audit Research Network criteria for major trauma from 2016 to 2020 in Ireland were included in this retrospective observational study. Incident data were retrieved from the Major Trauma Audit, while data on population density were calculated from Irish state sources. The primary outcome measure of survival to discharge was compared to population density using logistic regression, adjusted for demographic and incident variables. Records were divided into population density tertiles to assess for between-group differences in potential predictor variables. ResultsPopulation density at a receiving hospital had no impact on mortality in Irish major trauma patients from our logistic regression model (OR = 1.01, 95% CI 0.98–1.05, p = 0.53). Factors that did have an impact were age, Charlson Comorbidity Index, Injury Severity Score, and the presence of an Orthopaedic Surgery service at the receiving hospital (all p < 0.001). Age and Charlson Comorbidity Index differed slightly by population density tertile; both were higher in areas of high population density (all p < 0.001). ConclusionsSurvival to discharge in Irish major trauma patients does not differ substantially based on population density. This is an important finding as Ireland moves to a new trauma system, with features based on population distribution. An Orthopaedic Surgery service is an important feature of a major trauma receiving hospital and its presence improves outcomes.

Maternal outcomes of pregnant patients after trauma: a retrospective study of the Trauma Registry of England and Wales.

Trauma accounts for 20% of deaths in pregnant women. Injury characterisation and outcome in pregnant women following trauma is poorly described. To understand and inform optimum care of this key injury population, a study was conducted using the Trauma Audit Research Network (TARN) database. In total, 341 pregnant and 26,774 non-pregnant female patients aged 15 to 46 years were identified for comparison from the TARN database. Mortality, cross-sectional imaging, blood product administration and EQ-5D scores were compared between the two groups. Mechanism of injury, Injury Severity Score (ISS) and mortality rate before and after the creation of regional trauma networks were reported for pregnant patients. Pregnancy was recorded in 1.3% (341/27,115) of included patients, with the most common cause of injury being road traffic collisions. A reduction in crude maternal mortality was observed over the course of the study period (7.3% to 2.9%). Baseline mean EQ-5D (0.47) and EQ-VAS (54.08) improved to 0.81 (p < 0.001) and 85.75 (p = 0.001), respectively, at 6 months following injury. The incidence of trauma in pregnancy is small and mortality in injured pregnant women decreased over the study period. Pregnant patients have significantly improved patient-reported outcome measures 6 months after injury although this is limited in impact because of poor response rates and outcome reporting. Construction and validation of tools aiding in outcome reporting will help considerably in understanding further gains in the care of pregnant women.

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

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. 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. 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. 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 Posttaumatic Adjustment Scale (PAS) is an effective measure in predicting psychological distress in patients following major trauma

AimsTo determine whether a psychological screening tool - the Posttraumatic Adjustment Scale (PAS), predicts later psychological distress for admissions to a Major Trauma Centre (MTC) and to identify whether there was an unmet need in relation to the psychological support offered. MethodsPatient demographics and details of their injuries were retrieved from the Trauma Audit & Research Network (TARN) database. All patients admitted to Leeds General Infirmary MTC were approached for inclusion in the study over a three-month period. The PAS was administered to all participants at baseline. Following discharge, patients were sent two validated psychological measures via post, the Impact of Events Scale – Revised (IES-R) and the Clinical Outcomes in Routine Evaluation System (CORE-10). Relationships between continuous variables were examined using a Spearman's rank test (SR). The diagnostic accuracy of the different psychological screening systems was examined and compared using Receiver Operator Characteristic (ROC) analysis. ResultsEighty-two patients completed the PAS, 26 of whom had been referred to clinical psychology and 56 who were not. Fifty-seven of these patients (70%) returned follow-up IES-R and CORE-10 data, 20 who had been referred to psychology and 37 who had not. The PAS-P score recorded shortly after admission correlated strongly with the CORE-10 (SR rs 0.54, p<0.0001) and IES-R (SR rs 0.63, p<0.0001) scores recorded at early follow up. A PAS-P of more than 10 predicted the development of PTSD symptoms (IES-R 33 or more) or moderate global psychological distress (CORE-10 15 or more) with 72% sensitivity and 71% specificity. To identify patients who went on to develop psychological symptoms according to either measure (IES-R 33 or more or CORE-10 15 or more), the PAS-P was more sensitive than clinician referral (71% vs 52%, p<0.05) with similar specificity (72% vs 75%, p=0.78). ConclusionsIn an unselected group of trauma inpatients treated in a MTC, the PAS is an effective means of identifying those who are likely to go on to suffer PTSD symptoms or psychological distress. It may useful to use the PAS as a measure to formalise psychology referrals.

Trauma emergency thoracotomy for resuscitation in shock—a multi-centre evaluation of current UK practice of pre-hospital and emergency department resuscitative thoracotomy in trauma

Abstract Background Resuscitative thoracotomy (RT) in traumatic cardiac arrest, in particular for penetrating trauma features within several national guidelines. However, evidence surrounding its practice is poor, consisting of predominantly small-scale observational studies. Survival is generally poor, estimated at 3–13%, with better outcomes in penetrating trauma. There is no national RT database and the Trauma Audit Research Network data misses those who have died pre-hospital. It is important that a more in-depth and accurate national picture of thoracotomy practice is developed nationally to guide future practice. Traumatic emergency thoracotomy for resuscitation in shock (TETRiS) is a multi-centre, prospective and observational evaluation of current RT practice in the UK. Aims and objectives The aim of TETRiS is to evaluate the pathway of care for RT patients within the UK. This will be undertaken over a period of 12 months. This project will evaluate thoracotomies undertaken both pre-hospital and in emergency departments, examining various parameters including frequency, who performs the procedure, clinical indications, time from injury to initiation, mechanism of injury, injuries identified, interventions performed and patient outcomes. Methods This project is being conducted as a collaboration between the National Trauma Research and Innovation Collaborative, the Pre-Hospital Trainee Operated Research Network, the Trainee Emergency Research Network and the National HEMS Research and Audit Forum (NHRAF). All UK HEMS, helicopter emergency medicine services and major trauma centre (MTCs) nationally have been recruited, with site investigators identified within each participating unit. Inclusion criteria: All patients undergoing RT, pre-hospital or in an MTC emergency department will be included.

Major trauma associated with mobility scooters: An analysis of the trauma audit research network

AimsTo establish the incidence and nature of injuries seen in patients following mobility scooter incidents. MethodsThe Trauma Audit and Research Network (TARN) database was used to collect data concerning injuries associated with mobility scooters. The data was taken from incidents that occurred between February 2014 and November 2020. The data analysed included: patient demographics, injury mechanism and patterns and associated mortality rates. Results1,504 patients were identified of which 61.4% were male. The median age was 76.2 years (IQR 63.5–84.9). The median injury severity score (ISS) was 9 (IQR 9–17), with major trauma (ISS ≥16) being observed in 29.4% of patients. Injuries to the limb were most common, although injuries to the head were most severe. Vehicle collisions accounted for 65.4% of injuries and were most closely associated with the most severe incidents. The median length of stay in hospital was 12 days, excluding the patients who died. Overall, mortality following injury was 10.6%, but the mortality rate was 15.4% in those aged 75 years and over, and 24.2% in those sustaining severe trauma. ConclusionAs the population ages, injury characteristics of those with both major and non-major trauma changes. Mobility scooter use is prevalent amongst older people, and we provided a detailed analysis of injuries sustained with their use across a national database. The length of stay and the inherent resource use, because of admission following mobility scooter trauma, is considerable. These injuries particularly affect the ‘most elderly’ and carry a considerable mortality burden.

Head injury among older adults and their clinical management: one year of emergency department attendances at a UK trauma center

ABSTRACT Objectives Primary: describe characteristics of adults aged ≥65 attending the Emergency Department (ED) at one major trauma center. Secondary: examine co-morbidities and complications; identify use of anticoagulant/antiplatelet medication among older adults presenting with Head Injury (HI); assess clinical management against UK guidelines. Methods All ED admissions were screened prospectively to identify HI using case notes, hospital records and Trauma Audit Research Network data. Data were collected on demographics, cause and severity of injury, co-morbidities, anticoagulation/antiplatelet use, diagnostic imaging and discharge outcomes. Results Over 12 months, 697 patients aged ≥65 years attended the ED for HI, representing over a quarter of adult ED attendances for HI. Mean age was 78.5 years (range 65–106), 395 (56.7%) were female. Most HIs were mild (93.5%) and 86% caused by falls. Three-quarters were discharged without hospital admission. Most had a preexisting medical condition andtaking medications prior to HI. Of these 116 were taking anticoagulants/antiplatelets but only 37 (31.9%) received a head CT scan. Half the patients were given a written HI information sheet at ED discharge. Conclusions Care of HI in older adults is challenging due to comorbidities. Practising evidence-based clinical management and following guidelines is important, but strict adherence is not common practice.

Interventions to optimise the outputs of national clinical audits to improve the quality of health care: a multi-method study including RCT

Background National clinical audit programmes aim to improve patient care by reviewing performance against explicit standards and directing action towards areas not meeting those standards. Their impact can be improved by (1) optimising feedback content and format, (2) strengthening audit cycles and (3) embedding randomised trials evaluating different ways of delivering feedback. Objectives The objectives were to (1) develop and evaluate the effects of modifications to feedback on recipient responses, (2) identify ways of strengthening feedback cycles for two national audits and (3) explore opportunities, costs and benefits of national audit participation in a programme of trials. Design An online fractional factorial screening experiment (objective 1) and qualitative interviews (objectives 2 and 3). Setting and participants Participants were clinicians and managers involved in five national clinical audits – the National Comparative Audit of Blood Transfusions, the Paediatric Intensive Care Audit Network, the Myocardial Ischaemia National Audit Project, the Trauma Audit &amp; Research Network and the National Diabetes Audit – (objective 1); and clinicians, members of the public and researchers (objectives 2 and 3). Interventions We selected and developed six online feedback modifications through three rounds of user testing. We randomised participants to one of 32 combinations of the following recommended specific actions: comparators reinforcing desired behaviour change; multimodal feedback; minimised extraneous cognitive load for feedback recipients; short, actionable messages followed by optional detail; and incorporating ‘the patient voice’ (objective 1). Main outcome measures The outcomes were intended actions, including enactment of audit standards (primary outcome), comprehension, user experience and engagement (objective 1). Results For objective 1, the primary analysis included 638 randomised participants, of whom 566 completed the outcome questionnaire. No modification independently increased intended enactment of audit standards. Minimised cognitive load improved comprehension (+0.1; p = 0.014) and plans to bring audit findings to colleagues’ attention (+0.13, on a –3 to +3 scale; p = 0.016). We observed important cumulative synergistic and antagonistic interactions between modifications, participant role and national audit. The analysis in objective 2 included 19 interviews assessing the Trauma Audit Research Network and the National Diabetes Audit. The identified ways of strengthening audit cycles included making performance data easier to understand and guiding action planning. The analysis in objective 3 identified four conditions for effective collaboration from 31 interviews: compromise – recognising capacity and constraints; logistics – enabling data sharing, audit quality and funding; leadership – engaging local stakeholders; and relationships – agreeing shared priorities and needs. The perceived benefits of collaboration outweighed the risks. Limitations The online experiment assessed intended enactment as a predictor of actual clinical behaviour. Interviews and surveys were subject to social desirability bias. Conclusions National audit impacts may be enhanced by strengthening all aspects of feedback cycles, particularly effective feedback, and considering how different ways of reinforcing feedback act together. Future work Embedded randomised trials evaluating different ways of delivering feedback within national clinical audits are acceptable and may offer efficient, evidence-based and cumulative improvements in outcomes. Trial registration This trial is registered as ISRCTN41584028. Funding details This project was funded by the National Institute for Health and Care Research (NIHR) Health and Social Care Delivery Research programme and will be published in full in Health and Social Care Delivery Research; Vol. 10, No. 15.

Opportunities to improve the impact of two national clinical audit programmes: a theory-guided analysis

BackgroundAudit and feedback is widely used in healthcare improvement, with evidence of modest yet potentially important effects upon professional practice. There are approximately 60 national clinical audit programmes in the UK. These programmes often develop and adapt new ways of delivering feedback to optimise impacts on clinical practice. Two such programmes, the National Diabetes Audit (NDA) and the Trauma Audit Research Network (TARN), recently introduced changes to their delivery of feedback. We assessed the extent to which the design of these audit programmes and their recent changes were consistent with best practice according to the Clinical Performance Feedback Intervention Theory (CP-FIT). This comprehensive framework specifies how variables related to the feedback itself, the recipient, and the context operate via explanatory mechanisms to influence feedback success.MethodsWe interviewed 19 individuals with interests in audit and feedback, including researchers, audit managers, healthcare staff, and patient and public representatives. This range of expert perspectives enabled a detailed exploration of feedback from the audit programmes. We structured interviews around the CP-FIT feedback cycle and its component processes (e.g. Data collection and analysis, Interaction). Our rapid analytic approach explored the extent to which both audits applied features consistent with CP-FIT.ResultsChanges introduced by the audit programmes were consistent with CP-FIT. Specifically, the NDA’s increased frequency of feedback augmented existing strengths, such as automated processes (CP-FIT component: Data collection and analysis) and being a credible source of feedback (Acceptance). TARN’s new analytic tool allowed greater interactivity, enabling recipients to interrogate their data (Verification; Acceptance). We also identified scope for improvement in feedback cycles, such as targeting of feedback recipients (Interaction) and feedback complexity (Perception) for the NDA and specifying recommendations (Intention) and demonstrating impact (Clinical performance improvement) for TARN.ConclusionsThe changes made by the two audit programmes appear consistent with suggested best practice, making clinical improvement more likely. However, observed weaknesses in the feedback cycle may limit the benefits of these changes. Applying CP-FIT via a rapid analysis approach helps identify strengths and remediable weaknesses in the design of audit programmes that can be shared with them in a timely manner.

Changing Demographic Trends in spine trauma: The presentation and outcome of Major Spine Trauma in the elderly

IntroductionMajor trauma has seen a demographic shift in recent years and it is expected that the elderly population will comprise a greater burden on the major trauma service in the near future. However, whether a similar trend exists in those undergoing operative intervention for spinal trauma remains to be elucidated. AimsTo compare the presentation and outcomes of patients ≥65 years of age sustaining spine trauma to those <65 years at a national tertiary referral spine centre. MethodsThe local Trauma Audit Research Network (TARN) database was analysed to identify spinal patients referred to our institution, a national tertiary referral centre, between 01/2016 and 05/2019. Patients were divided into a young cohort (16–64 years old) and an elderly cohort (> 64 years old). No explicit distinction was made between major and minor spine trauma cases. Variables analysed included patient demographics, injury severity, mortality, interventions, mechanism of injury and length of hospital stay. ResultsA total of 669 patients were admitted of which 480 patients underwent operative intervention for spinal trauma. Within the elderly cohort, this represented 75.3% of cases. Among the younger population, road traffic collisions were the most common mechanism of injury (37.1%), while low falls (<2 m) (57.4%) were the most common mechanism among the older population. Patients ≥65 years old had significantly longer length of stay (21 days [1–194] v 14 days [1–183]) and suffered higher 30-day mortality rates (4.6% [0–12] v 0.97% [0–4]). ConclusionOrthopaedic spinal trauma in older people is associated with a significantly higher mortality rate as well as a longer duration of hospitalization. Even though severity of injury is similar for both young and old patients, the mechanism of injury for the older population is of typically much lower energy compared to the high energy trauma affecting younger patients.

The Cheshire & Merseyside Collaborative trainee-led on-call service: a review of safety and efficiency

To assess safety and efficiency of the Cheshire & Merseyside Collaborative, the largest trainee led on-call service in the UK, based on discrepancy rates and time taken to issue reports. All studies reported by the collaborative in a 4-week period were evaluated for discrepancy and the time taken to issue a report. These figures were compared against the Royal College of Radiologists (RCR) guidelines and a recent national audit of discrepancy rates. The time taken to report was measured against the National Institute of Health and Clinical Excellence (NICE) and Trauma Audit Research Network (TARN) guidelines. The overall discrepancy rates for the collaborative were 2.5% for minor discrepancies and 2% for major discrepancies, which is within the RCR standard. The median time taken to issue a report was 30 min, which is within the NICE and TARN 1-h targets. The Cheshire & Merseyside Collaborative can be deemed a safe and efficient way of delivering an out-of-hours radiology service.

Outcome of selective CT vs. pan-CT scan in elderly trauma patients: A retrospective cohort study in a level 1 trauma center

PurposeThere are currently no clear guidelines for use of pan- or selective CT in elderly trauma patients and this subject matter remains controversial. The aim of this study is to compare the outcome of elderly trauma patients in a level 1 trauma centre who required a pan- or selective CT scan on admission. MethodsThe Trauma Audit Research Network database was reviewed to identify eligible patients (≥65 years) over a one-year period, from January 2018 to January 2019. Patients’ demographics, mechanism of injury, injury severity score, length of hospital stay (LOS), mortality and type of CT scans done were recorded. The inclusion criteria were elderly patients ≥65 years involved in acute trauma setting (less than one day between incident and emergency department presentation and blunt mechanism of injury). Exclusion criteria were patients <65 years, perforating mechanism of injury and patients with delayed presentation more than one day after the incident, and patients who have not got any CT scan at presentation. Statistical analyses were undertaken on SPSS (version 25.0; IBM, New York, USA). ResultsIn total, 481 patients with the mean age of 80.8 years were evaluated (48.6% male). Among them 232 cases were multiple injuries while 249 were single system injuries. And 235 patients (48.8%) underwent pan-CT in whom 66.8% were multiple injuries; 246 (51.1%) did selective CT scan in whom 69.5% were single system injuries. In multiple injury patients, performing a pan-CT scan on presentation was associated with shorter LOS compared to those who had a selective CT, in which 76.4% patients spent < 21 days in the pan-CT group compared to 16.0% for those investigated by selective CT scan (p < 0.001); and 2.5% spent > 60 days in pan-CT group compared to 64% in selective CT group (p < 0.0001). Performing pan-CT was also associated with lower need to repeat CT (p < 0.01). In patients with a single system injury, no differences were found in LOS or the need to repeat CT if either pan-CT or selective CT were requested. ConclusionWe recommend doing pan-CT scan in all elderly patients with multiple system injuries as it decreases the LOS and the need for another CT during hospital stay. No difference in LOS or the need to repeat another CT if pan-CT or selective CT were requested initially in single system injuries. Although age and injury severity score are poor predictors for the need to do pan-CT, the mechanism of injury may be helpful.

National temporal variation in major trauma in England, Wales and Northern Ireland

Introduction Trauma is one of the leading causes of mortality worldwide, but little is known of the temporal variation in major trauma across England, Wales and Northern Ireland. Proper workforce and infrastructure planning requires identification of the caseload burden and its temporal variation. Materials and Methods The Trauma Audit Research Network (TARN) database for admissions attending Major Trauma Centres (MTCs) between 1st April 2011 and 31st March 2018 was analysed. TARN records data on all trauma patients admitted to hospital who are alive at the time of admission to hospital. Major trauma was classified as an Injury Severity Score (ISS) &gt;15. Results A total of 158,440 cases were analysed. Case ascertainment was over 95% for 2013 onwards. There was a statistically significant variation in caseload by year (p &lt; 0.0001), times of admissions (p &lt; 0.0001), caseload admitted during weekends vs weekdays, 53% vs 47% (p &lt; 0.0001), caseload by season with most patients admitted during summer (p &lt; 0.0001). The ISS varied by time of admission with most patients admitted between 1800 and 0559 (p &lt; 0.0001), weekend vs weekday with more severely injured patients admitted during the weekend (p &lt; 0.0001) and by season p &lt; 0.0001). Discussion and Conclusion: There is a significant national temporal variation in major trauma workload. The reasons are complex and there are multiple theories and confounding factors to explain it. This is the largest dataset for hospitals submitting to TARN which can help guide workforce and resource allocation to further improve trauma outcomes.

Validation of the BATT score for prehospital risk stratification of traumatic haemorrhagic death: usefulness for tranexamic acid treatment criteria

BackgroundTranexamic acid reduces surgical blood loss and reduces deaths from bleeding in trauma patients. Tranexamic acid must be given urgently, preferably by paramedics at the scene of the injury or in the ambulance. We developed a simple score (Bleeding Audit Triage Trauma score) to predict death from bleeding.MethodsWe conducted an external validation of the BATT score using data from the UK Trauma Audit Research Network (TARN) from 1st January 2017 to 31st December 2018. We evaluated the impact of tranexamic acid treatment thresholds in trauma patients.ResultsWe included 104,862 trauma patients with an injury severity score of 9 or above. Tranexamic acid was administered to 9915 (9%) patients. Of these 5185 (52%) received prehospital tranexamic acid. The BATT score had good accuracy (Brier score = 6%) and good discrimination (C-statistic 0.90; 95% CI 0.89–0.91). Calibration in the large showed no substantial difference between predicted and observed death due to bleeding (1.15% versus 1.16%, P = 0.81). Pre-hospital tranexamic acid treatment of trauma patients with a BATT score of 2 or more would avoid 210 bleeding deaths by treating 61,598 patients instead of avoiding 55 deaths by treating 9915 as currently.ConclusionThe BATT score identifies trauma patient at risk of significant haemorrhage. A score of 2 or more would be an appropriate threshold for pre-hospital tranexamic acid treatment.

Open lower limb fractures in the UK trauma system: A multicentre prospective audit of current practice.

Open fractures represent limb-threatening and life-changing injuries. Clear standards define how patients with these injuries should be managed in the UK. The study of open fractures is, therefore, a key measurable example of major trauma management as a whole. This study was conducted to characterise the demographic, assessment and treatment of patients sustaining lower limb open fractures across UK Regional Trauma Networks. A prospective, multicentre, audit was conducted according to a prespecified protocol against the relevant British Orthopaedic Association (BOA) & British Association of Plastic, Reconstructive & Aesthetic Surgeons (BAPRAS) standards for Trauma. All UK hospitals treating adults with open fractures were eligible to take part in the study. Patients included were injured during a six month collection period at each site. 3 Major Trauma Centres (MTCs) and 5 Trauma Units (TUs) were enrolled, with data collected by 24 collaborators. 239 patients were included, 11 had bilateral open fractures. There were 38 patient datasets collected from TUs and 201 from MTCs. Patients were predominantly male with high energy injuries. 31.3% of patients from MTCs were transferred in from another facility. Antibiotics were given to 41.7% of patients within 1 hour. 74.4% of limbs with open fractures had a splint applied in the emergency department. 85.8% of patients had a documented orthoplastics plan. 41.7% of patients with a high energy injury had their wound debrided within 12 hours. 42.3% of patients with open fractures in our cohort were managed at some point in a TU, indicating triage was required within the trauma network. Due to sampling, we may be under-estimating the number of patients passing through TUs, however, we have demonstrated that this cohort exists. These patients are under-represented in many other studies and registries such as the Trauma Audit Research Network (TARN) due to the funding model for data collection that privileges data collection in MTCs. This study gives extensive new insight into the demographics and management of patients with open lower limb fractures in the UK, demonstrating a widespread involvement of TUs and consistent deviation from national standards.

Head and neck injury in major trauma in Ireland: a multicentre retrospective analysis of patterns and surgical workload.

Head and neck injuries are common in major trauma patients, but the prevalence is poorly documented in the literature. This study aims to investigate this further, particularly in the context of increasing development of Irish and European trauma systems. To determine the prevalence of, and patterns behind head and neck injury in major trauma in an Irish population. The Trauma Audit Research Network database was analysed for major trauma patients (injury severity score > 15) with head and neck injuries admitted to any of the 26 participating hospitals in the Republic of Ireland between 2014 and 2017. The data was studied for patterns in the epidemiology of injuries and outcomes. A total of 5364 patients were identified. Males were affected more than females (M:F 2.1:1). The most common mechanism of injury was falls. There were 1272 counts of soft tissue injury, and 5814 counts of bony injury recorded within the cohort. Twenty-six percent of patients underwent some form of surgical procedure. Median length of hospital stay was 8days, and the 30-day survival rate was 90%. A substantial number of Irish major trauma patients of all ages and genders sustain some form of head and neck injury. It produces significant injury and surgical workload involving input from multiple disciplines.

High Riding Prostate: Epidemiology of Genitourinary Injury in Motorcyclists from a UK Register of over 12,000 Victims

Background: The mechanism of motorcycle accidents (high speeds, pelvis behind fuel tank) may predispose to genitourinary injury (GUI) but the epidemiology is poorly understood. Previous studies have assessed GUI patterns in cyclists, and road traffic accident victims in general, but no study has analyzed GUI patterns in a large cohort of motorcyclists. Objectives: We aimed to better understand patterns of urological injuries among motorcyclists admitted to hospital. We aimed to determine any relationship between pelvic fracture and GUI patterns or severity. Methods: The Trauma Audit Research Network was reviewed to identify motorcyclists admitted between January 2012 and December 2016 (n = 12,374). Cases were divided into riders (n = 11,926) and pillion passengers (n = 448), and the data analyzed to identify urological injuries and their associations. The associations between pelvic fracture and other injury types were tested for significance by one- and two-way χ². Results: GUI was identified in 6%. Renal trauma was the most common GUI among riders (4%) and pillions (2%). There was no statistically significant relationship between grade of renal trauma and presence of pelvic fracture. Urethral injury occurred in 0.2% of riders and passengers, and bladder injury in 0.4% of riders and 0.7% of pillions. Urethral and bladder injuries were positively associated with pelvic fracture, which was present in 81 and 92%, respectively. Testicular trauma occurred in 0.4% of riders and 0.7% of pillions. Body armor was recorded in 3% of casualties with urological trauma, and 3% overall. Conclusions: A significant proportion of motorcyclists brought to accident and emergency department have GUI, most commonly renal trauma. Pelvic fracture is more common in pillion passengers than riders, and associated with urethral and bladder injuries, but it does not predict severity of renal trauma. External genital injuries are rare, but we recommend examination in the tertiary survey, as consequences of missed injury are severe. Further research is needed to explore protective effects of motorcyclist clothing.
