The accuracy of prehospital triage decisions in English trauma networks – a case-cohort study

BackgroundCare for injured patients in England is provided by inclusive regional trauma networks. Ambulance services use triage tools to identify patients with major trauma who would benefit from expedited Major Trauma Centre (MTC) care. However, there has been no investigation of triage performance, despite its role in ensuring effective and efficient MTC care. This study aimed to investigate the accuracy of prehospital major trauma triage in representative English trauma networks.MethodsA diagnostic case-cohort study was performed between November 2019 and February 2020 in 4 English regional trauma networks as part of the Major Trauma Triage Study (MATTS). Consecutive patients with acute injury presenting to participating ambulance services were included, together with all reference standard positive cases, and matched to data from the English national major trauma database. The index test was prehospital provider triage decision making, with a positive result defined as patient transport with a pre-alert call to the MTC. The primary reference standard was a consensus definition of serious injury that would benefit from expedited major trauma centre care. Secondary analyses explored different reference standards and compared theoretical triage tool accuracy to real-life triage decisions.ResultsThe complete-case case-cohort sample consisted of 2,757 patients, including 959 primary reference standard positive patients. The prevalence of major trauma meeting the primary reference standard definition was 3.1% (n=54/1,722, 95% CI 2.3 – 4.0). Observed prehospital provider triage decisions demonstrated overall sensitivity of 46.7% (n=446/959, 95% CI 43.5-49.9) and specificity of 94.5% (n=1,703/1,798, 95% CI 93.4-95.6) for the primary reference standard. There was a clear trend of decreasing sensitivity and increasing specificity from younger to older age groups. Prehospital provider triage decisions commonly differed from the theoretical triage tool result, with ambulance service clinician judgement resulting in higher specificity.ConclusionsPrehospital decision making for injured patients in English trauma networks demonstrated high specificity and low sensitivity, consistent with the targets for cost-effective triage defined in previous economic evaluations. Actual triage decisions differed from theoretical triage tool results, with a decreasing sensitivity and increasing specificity from younger to older ages.

IMPACT OF REGIONALIZATION OF MAJOR TRAUMA SERVICES ON HIP FRACTURE CARE IN ENGLAND: A COMPARATIVE STUDY

Following the establishment of regional Major Trauma Networks in England in 2012, there were concerns that pressures regarding resource allocation in Major Trauma Centres (MTCs) may have a detrimental impact on the care of patients with hip fractures in these hospitals. This study aimed to compare outcomes in hip fracture care between MTCs and trauma units (TUs).National Hip Fracture Database data was extracted from 01/01/2015 to 31/12/2022 for all hospitals in England. Outcome measures included perioperative medical and physiotherapy assessments, time to surgery, consultant supervision in theatre, Best Practice Tariff (BPT) compliance, discharge to original residence, and mortality. Data was pooled and weighted for MTCs and remaining hospitals (TUs).A total of 487,089 patients with hip fractures were included from 167 hospitals (23 MTCs and 144 TUs). MTCs achieved marginally higher rates of orthogeriatrician assessment within 72 hours of admission (91.1% vs 90.4%, p<0.001) and mobilisation out of bed by first postoperative day (81.9% vs 79.7%, p<0.001). A lower proportion of patients underwent surgery by the day after admission in MTCs (65.2% vs 69.7%, p<0.001). However, there was significantly higher consultant surgeon and anaesthetist supervision rates during surgery in MTCs (71.8% vs 61.6%, p<0.001). There was poorer compliance with BPT criteria in MTCs (57.3% vs 60.4%, p<0.001), and proportionately fewer MTC patients were discharged to their original residence (63.5% vs 60.4%, p<0.001). There was no difference between MTCs and TUs in 30-day mortality (6.8% vs 6.8%, p=0.825).This study demonstrates that MTCs have greater difficulty in providing prompt surgery to hip fracture patients. However, their marginally superior perioperative care outcomes appear to compensate for this, as their mortality rates are similar to TUs. These findings suggest that the regionalisation of major trauma in England has not significantly compromised the overall care of hip fracture patients.

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.

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

IntroductionCurrent 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. MethodologyORTHOPOD 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. ResultsFollowing 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. ConclusionMost 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.

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.

Use of a trauma registry to drive improvement in the regional trauma network systems in Hawassa, Ethiopia

AimOur aim is to establish and analyse the first year of trauma registry data from Hawassa University Comprehensive Specialised Hospital (HUCSH)—an Ethiopian tertiary referral centre. We plan to identify possible trends in injury patterns, access to health care and referral pathways and establish if our observations are in keeping with data published from other sub-Saharan LMIC’s.MethodsProspective data collection using the WHO trauma registry dataset. All trauma patients presenting to HUCSH between November 2019 and November 2020 were included. Military patients were excluded. Dataset: Age, sex, region of residence, mode of transport to hospital, referral centre, time from injury to arrival in HUCSH, arrival triage category, Kampala Trauma Score (KTS), mechanism of injury, injury type, closed/open fracture and 24 h outcomes. Data statistical analysis was performed to calculate frequencies of the above variables.ResultsThere were a total of 1919 cases. Fifty-three per cent were caused by road traffic collision and 49% were fracture/dislocations. Public transport was the most common mode to hospital—40%. Seventy-seven per cent of all trauma admissions were referred from other centres, 69% had a mild KTS. A total of 376 patients presented with an open fracture—76% had a low KTS and 67% remained in ED for > 24 h. Sixty-five per cent of ambulances were utilised for mild KTS patients, only 25% of ambulances transported moderate and severe injuries.ConclusionWe have shown that a ‘one size fits all approach’ should not be adopted for LMIC’s as trends vary between regions and countries. Improvements are needed in ambulance utilisation, the use of appropriate triaging tools to facilitate initial basic trauma care and appropriate, timely referrals and the management of open fractures.

Single centre experience with the superficial circumflex iliac artery perforator (SCIP) flap for traumatic limb defects: A case-series for first year as a regional major trauma network during a global pandemic

The free superficial circumflex iliac artery perforator (SCIP) flap evolved from the traditional groin flap, conferring numerous advantages. The thin nature of the flap avoids the need for secondary revisions and debulking procedures, particularly pertinent when theatre capacity was limited during the COVID-19 pandemic. We present a series reporting our centre's first year experiences undertaking SCIP flap reconstruction for traumatic limb injuries following the establishment of our regional major trauma network. A retrospective analysis of all patients treated for traumatic limb defects in our centre was undertaken between September 2020 to September 2021. Data was collected on patient demographics, injury, flap dimensions and flap survival. Ten patients (M:F 1:1, mean age 45 years) with traumatic limb defects were reconstructed with SCIP flaps performed by the senior authors. All had sustained open fractures. Nine had lower limb defects, most commonly at the medial ankle, one had a volar wrist defect with a devascularised hand. The mean flap dimension was 6.3 × 14.5 cm. All were anastomosed end-to-side to the recipient artery except one end-to-end anastomosis to a posterior tibial artery perforator using super-microsurgery. There was 100% flap survival. Complications consisted of one flap suffering <10% tip necrosis requiring debridement and small skin graft. The SCIP flap provides reliable, thin and pliable tissue without the need for secondary flap revisions and should be considered in the armamentarium of the reconstructive surgeon in extremity trauma reconstruction, particularly in the current environment surrounding the global pandemic. • The free superficial circumflex iliac artery perforator (SCIP) flap evolved from the traditional groin flap, conferring numerous advantages. • The thin nature of the flap avoids the need for secondary revisions and debulking procedures, particularly pertinent when theatre capacity was limited during the COVID-19 pandemic. • We demonstrate that SCIP flap provides reliable, thin and pliable tissue without the need for secondary flap revisions and should be considered in the armamentarium of the reconstructive surgeon in extremity trauma reconstruction, particularly in the current environment surrounding the pandemic.

714 ‘Administration of Tranexamic Acid in Traumatic Brain Injury in a Major London Trauma Centre’

Abstract Aim Traumatic brain injury contributes to worldwide death and disability more than any other traumatic insult. CRASH-3 demonstrated tranexamic acid is safe in mild to moderate traumatic brain injury and head injury-related death was reduced when given within 3 hours of injury. This project aims to review adherence to the recommendations at a major trauma centre and implement changes with the view of improving outcomes. Method Patients presenting at St Mary's Hospital with a traumatic head injury over a 6-month period were identified. Data collection included: timings of injury and tranexamic acid administration, Glasgow Coma Scale at the scene and admission, and bolus vs. bolus and infusion. Results presented at the regional trauma network meeting with summary poster designed for display in the department. A second cycle of data collection was completed over 2 months following the interventions. Results There was an increase in the proportion of patients who received tranexamic acid from 29% in cycle 1 to 51% in cycle 2. The proportion of patients receiving both the initial bolus and infusion also increased from 25% in cycle 1 to 45% in cycle 2. The average time from injury to first dose of tranexamic acid was reduced from 2 hours 16 minutes to 1 hour 33 minutes. Conclusions The interventions implemented between cycles 1 and 2 led to an overall improvement in the major trauma unit's adherence to the CRASH-3 recommendations. Decisions where tranexamic acid is withheld are down to clinical judgement however it is recommended that the reasoning is also documented.

The national major trauma system within the United Kingdom: inclusive regionalized networks of care

Abstract The United Kingdom has a population of 67 million people and is divided into 4 nations: England, Wales, Scotland, and the North of Ireland. Healthcare is provided free to all within each nation via the National Health Service (NHS), which is funded by taxes and national insurance payments. Each year, there are approximately 22,000 cases of “major trauma” in the UK across the four nations. Prior to 2010, trauma patients in the UK were managed at any acute hospital with an Emergency Department, irrespective of resource availability or clinical experience and expertise. In the late 2000s, national reports identified significant variation or serious failings in the organization of UK trauma care. These reports, together with political drivers for centralized services, led to the formation of the national major trauma system made up of regional trauma networks. England was the first nation to implement the system in 2012 and this re-organization of major trauma care was associated with a 19% increase in the odds of survival for patients who reached hospital alive. This paper will provide an overview of the positive attributes and challenges within 6 key components of the national trauma system: pre-hospital care, facility-based care, trauma networks, the trauma registries, rehabilitation and governance, financing, and quality assurance.

Regional variation in the provision of major trauma services for the older injured patient

IntroductionThe establishment of national trauma networks have resulted in significant benefits to injured patients. Older people are the majority of major trauma patients and there is need to study variations in care and performance against clinical metrics for them. We aim to describe this patient group in terms of injury, demographics, episode of care assessment and variation between component regions of the Major Trauma Network of England and Wales. MethodThe Trauma Audit and Research Network (TARN) database was analysed from April 2017 to March 2019. Patients aged 65 years and above with injury severity score (ISS) greater than eight were selected for analysis. Patients were compared by care pathway in terms of first and second treating hospitals and by demographics, injury mechanism, severity, physiology at arrival to hospital (including Glasgow Coma Score (GCS)) and mortality, where known, at discharge. ResultsFifty-three thousand three hundred and forty-seven older injured patients (median age 82.5 years and 58.2% female), were treated in 165 hospitals within the 17 regional trauma networks over the two-year study period. Aside from GCS and gender, all other patient characteristics were significantly different between networks and specifically, a large variation between the network with the highest proportion of older patients (60.4%) and that with a preponderance of younger patients (40.2%) is seen. 84% of cases were due to a fall <2 m and 36.7% of cases had a brain injury. 73.5% of cases had one or more comorbidities. DiscussionWe have increased the understanding of how older patients contribute to and are managed by a national trauma service. We have demonstrated variation in numbers and patient characteristics throughout regional trauma networks. We have detailed the whole patient episode, allowing us to comment on disparities in management such as senior review and access to specialist clinical care settings. Older patients dominate United Kingdom major trauma and considerable variations and shortfalls have been identified. Work is needed to focus on the whole clinical episode for these patients both to improve outcome and patient experience but to also to ensure sustainable clinical care in a resource deplete era.

Exploring the factors that influence trauma team activation in emergency department staff.

Regional trauma networks enable the rapid and safe management and transfer of patients with traumatic injury between designated trauma units and one of 27 major trauma centres throughout the UK. Multispecialty trauma teams are available 24 hours a day, seven days a week, and are activated immediately upon receipt of a patient presenting with major trauma. With most serious trauma patients going direct to major trauma centres rather than a less specialised hospital-based trauma unit, it can be challenging for hospital-based trauma unit staff to gain experience and skill in this area, leading to potential inconsistencies in the process of activating the trauma team. The aim of this service evaluation was to identify factors influencing the decision to activate the trauma team in emergency department (ED) staff working within a 700-bed trauma unit. A questionnaire was sent to 107 staff and 70 completed it, a response rate of 65%. Results indicated that shortfalls in trauma-specific training, lack of clinical experience, undefined roles and responsibilities, department culture, ambulance handover, knowledge of clinical guidelines and previous experience of trauma team activation all affected the decision to activate the trauma team. Trauma-specific training and the support of senior staff could enhance confidence and appropriate trauma team activation rates.

Epidemiology of traumatic spinal cord injury: a large population-based study.

Study designA retrospective population-based study.ObjectivesDescribe the incidence of traumatic spinal cord injury (TSCI) and mortality risks, based on the characteristics of the patient, anatomical level of the lesion, setting/cause of the injury, and type of healthcare support received within the regional trauma network (highly specialized trauma center or spoke hospital).SettingBetween 2011 and 2020, 1303 patients with incident TSCI were identified in a population of 4.9 million inhabitants.MethodsHospital discharge records and mortality records were used to identify patients and outcomes. Cox regression models were fitted to estimate mortality risks across several subgroups.ResultsOver the past decade, age-sex-standardized TSCI incidence rates remained stable with 26.5 cases (95% CI, 25.0–27.9) per 1,000,000 inhabitants (mean age 59.2 years) and most cases were males (68.3%). Incidence was directly associated with age while the male to female ratio was inversely related. Most TSCIs were cervical lesions (52.1%), and the most common cause of injury were traffic crashes (29.9%) followed by occupational accidents (29.8%). Sex, cause of the trauma, or inpatient hospital management were not associated with an increased risk of death. Mortality rates were greater for cervical lesions, and increased with age, remaining stably high among older individuals even 12 months after the accident. One-month mortality risk was significantly higher at ≥75 years compared to <55 years (adjusted HR 9.14 (95% CI, 4.17–20.03)).ConclusionPublic health policies should aim at reducing preventable TSCIs, and special attention should be drawn to long-term management of elderly patients in the attempt to decrease mortality rates.

Resource utilisation for patients brought to a major trauma centre by helicopter

BackgroundHelicopter Emergency Medical Services (HEMS) allow critical care personnel to attend incidents alongside transporting patients to hospital. The study site is a UK based emergency department and major trauma centre, accepting flights from a wide geographical area. AimsTo characterise the impact of HEMS on a major trauma centre clinical resources and the impact of the UK regional trauma network launch on HEMS asset provision. MethodsFlight case-mix data were obtained from Emergency Department (ED) records (non-trauma patients) and from the Trauma Audit and Research Network database (trauma patients). Statistical analysis was in Excel. Results432 flights landed at the site between August 2018 and July 2019. 178 flights originated from the incident scene (145 trauma, 26 non-trauma), 107 from other hospitals, and 5 to other hospitals. Hospitalisation was reduced to a median of 6 days. ConclusionsPrimary HEMS trauma patients utilised significant clinical resources but had shorter hospitalisations than those without HEMS intervention. The regional trauma network improved HEMS tasking and utilised critical car cars to provide advanced pre-hospital care locally. Further work should compare HEMS versus ground ambulance to determine the impact of HEMS on patient outcomes and cost implications to both HEMS operators and receiving hospital.

Toward an all-inclusive trauma system in Central South Ontario: development of the Trauma-System Performance Improvement and Knowledge Exchange (T-SPIKE) project.

BackgroundThere is currently no integrated data system to capture the true burden of injury and its management within Ontario’s regional trauma networks (RTNs), largely owing to difficulties in identifying these patients across the multiple health care provider records. Our project represents an iterative effort to create the ability to chart the course of care for all injured patients within the Central South RTN.MethodsThrough broad stakeholder engagement of major health care provider organizations within the Central South RTN, we obtained research ethics board approval and established data-sharing agreements with multiple agencies. We tested identification of trauma cases from Jan. 1 to Dec. 31, 2017, and methods to link patient records between the various echelons of care to identify barriers to linkage and opportunities for administrative solutions.ResultsDuring 2017, potential trauma cases were identified within ground paramedic services (23 107 records), air medical transport services (196 records), referring hospitals (7194 records) and the lead trauma hospital trauma registry (1134 records). Linkage rates for medical records between services ranged from 49% to 92%.ConclusionWe successfully conceptualized and provided a preliminary demonstration of an initiative to collect, collate and accurately link primary data from acute trauma care providers for certain patients injured within the Central South RTN. Administration-level changes to the capture and management of trauma data represent the greatest opportunity for improvement.

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.

Thirty-Day Mortality for Proximal Femoral Fractures Treated at a U.K. Elective Center with a Site-Streaming Policy During the COVID-19 Pandemic.

Background:COVID-19 led to the reconfiguration of U.K. orthopaedic trauma services because surgical capacity was threatened in acute centers. We report the 30-day mortality of proximal femoral fractures in older adults treated at an elective orthopaedic center.Methods:Patients >60 years old who presented with a proximal femoral fracture to any of 4 sites in the regional trauma network were transferred to our elective center for emergency surgery. Care was modeled according to the National Institute for Health and Care Excellence guidelines, and efforts were made to treat all patients within 36 hours. Data were collected prospectively, and mortality outcomes were recorded.Results:Of the 192 patients who presented to the elective orthopaedic center, 167 were treated there. The median age of the latter patients was 88 years (interquartile range, 83 to 79 years). The median Charlson Comorbidity Index was 4 (interquartile range, 4 to 6). The median time from emergency department admission to surgical treatment was 24.5 hours (interquartile range, 18.8 to 34.7 hours). The 30-day rate of mortality was 10.2%. A total of 29 (17.4%) tested positive for COVID-19 during their admission, of whom 10 died, for a case-fatality rate of 34.5%. There were no significant differences in age (p = 0.33) or Charlson Comorbidity Index (p = 0.13) between patients who tested positive and those who did not. There was no significant difference in age between those who tested positive and died and those who tested positive and did not die (p = 0.13), but there was a significant difference in Charlson Comorbidity Index between those subgroups (p = 0.03).Conclusions:During a pandemic, an elective orthopaedic center can be reconfigured to a surgical center for older patients with proximal femoral fractures with acceptable health-care quality outcomes.Level of Evidence:Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Bypassing the nearest emergency department for a more distant neurosurgical centre in traumatic brain injury patients

Background and objective Major trauma triage within regional trauma networks (RTN) select patients with suspected TBI for bypass to specialist neuroscience centres (SNC), expediting neurosurgical care but may delay resuscitation. This comparative effectiveness study assessed the impact of this strategy on the risk adjusted hospital survival rates of patients confirmed to have intracranial injury on brain computed tomography (CT) scan. Method A retrospective cohort study was conducted using Trauma Audit and Research Network trauma registry data. Adult patients with a TBI on CT scan were included if they presented between June 2015 to February 2016 to SNCs or non-specialist acute hospitals (NSAH) in the North of England (South Cumbria, Lancashire and the North East Region). Patients were identified as having bypassed a nearer NSAH emergency department (ED) to a SNC using google maps. Their standardised excess survival rate was compared to TBI patients who received primary treatment at a NSAH. A multivariate logistic regression model predicting 30-day survival after TBI (Ps14n) 1 was used to adjust for variation in casemix between cohorts. Study design and results 355 patients met the study inclusion criteria, with 89/355 (25%) of TBI patients bypassing a nearer NSAH to a SNC, and 266/355 (75%) receiving primary treatment at an NSAH. The median severity of intracranial injury was equivalent (median Head Abbreviated Injury Scale 4 (IQR 4–5) in each group. There was no statistically significant difference in the standardised excess survival rate between the two cohorts; +6.15% for bypass (95% CI −1.24% to +13.55%) versus −1.12% for non-bypass (95% CI −4.51% to +2.25%). Conclusion and future research No statistically significant survival benefit was identified for TBI patients who bypassed the nearest ED to attend a SNC compared to those receiving treatment at the nearest NSAH, however a clinically significant 7% excess survival rate merits a larger study.

Age and the distribution of major injury across a national trauma system.

BackgroundTrauma places a significant burden on healthcare services, and its management impacts greatly on the injured patient. The demographic of major trauma is changing as the population ages, increasingly unveiling gaps in processes of managing older patients. Key to improving patient care is the ability to characterise current patient distribution.ObjectivesThere is no contemporary evidence available to characterise how age impacts on trauma patient distribution at a national level. Through an analysis of the Trauma Audit Research Network (TARN) database, we describe the nature of Major Trauma in England since the configuration of regional trauma networks, with focus on injury distribution, ultimate treating institution and any transfer in-between.MethodsThe TARN database was analysed for all patients presenting from April 2012 to the end of October 2017 in NHS England.ResultsAbout 307,307 patients were included, of which 63.8% presented directly to a non-specialist hospital (trauma unit (TU)). Fall from standing height in older patients, presenting and largely remaining in TUs, dominates the English trauma caseload. Contrary to perception, major trauma patients currently are being cared for in both specialist (major trauma centres (MTCs)) and non-specialist (TU) hospitals. Paediatric trauma accounts for <5% of trauma cases and is focussed on paediatric MTCs.ConclusionsWithin adult major trauma patients in England, mechanism of injury is dominated by low level falls, particularly in older people. These patients are predominately cared for in TUs. This work illustrates the reality of current care pathways for major trauma patients in England in the recently configured regional trauma networks.

A modern, multicenter evaluation of hepatic angioembolization – Complications and readmissions persist

BackgroundIndications for angioembolization (AE) following liver injury are not clearly defined. This study evaluated the outcomes and complications of hepatic AE. We hypothesize hepatic angioembolization is a useful adjunct to non-operative management of liver injury but with significant morbidity. MethodsSubjects were identified utilizing trauma registries from centers in a regional trauma network from 2010 to 2017 with an Abbreviated Injury Scale (AIS) coded hepatic injury and an ICD9/10 for hepatic angiography (HA). Results1319 patients with liver injuries were identified, with 30 (2.3%) patients undergoing HA: median ISS was 26, and median liver AIS was 4. Twenty-three subjects required AE. 81% had extravasation on CT from a liver injury. 63% underwent HA as initial intervention. 43% of AE subjects had liver-related complications with 35% 30-day readmission but with zero 30-day mortality. ConclusionsWhile there were zero reported deaths, a high rate of morbidity and readmission was found. This may be due to the angioembolization or the liver injury itself.

Give the trauma patient what they bleed, when and where they need it: establishing a comprehensive regional system of resuscitation based on patient need utilizing cold-stored, low-titer O+ whole blood.

Despite countless advancements in trauma care a survivability gap still exists in the prehospital setting. Military studies clearly identify hemorrhage as the leading cause of potentially survivable prehospital death. Shifting resuscitation from the hospital to the point of injury has shown great promise in decreasing mortality among the severely injured. Our regional trauma network (Southwest Texas Regional Advisory Council) developed and implemented a multiphased approach toward facilitating remote damage control resuscitation. This approach required placing low-titer O+ whole blood (LTO+ WB) at helicopter emergency medical service bases, transitioning hospital-based trauma resuscitation from component therapy to the use of whole blood, modifying select ground-based units to carry and administer whole blood at the scene of an accident, and altering the practices of our blood bank to support our new initiative. In addition, we had to provide information and training to an entire large urban emergency medical system regarding changes in policy. Through a thorough, structured program we were able to successfully implement point-of-injury resuscitation with LTO+ WB. Preliminary evaluation of our first 25 patients has shown a marked decrease in mortality compared to our historic rate using component therapy or crystalloid solutions. Additionally, we have had zero transfusion reactions or seroconversions. Transfusion at the scene within minutes of injury has the potential to save lives. As our utilization expands to our outlying network we expect to see a continued decrease in mortality among significantly injured trauma patients.
