RESUMEN
BACKGROUND: Preparatory, written plans for mass casualty incidents are designed to help hospitals deliver an effective response. However, addressing the frequently observed mismatch between planning and delivery of effective responses to mass casualty incidents is a key challenge. We aimed to use simulation-based iterative learning to bridge this gap. METHODS: We used Normalisation Process Theory as the framework for iterative learning from mass casualty incident simulations. Five small-scale 'focused response' simulations generated learning points that were fed into two large-scale whole-hospital response simulations. Debrief notes were used to improve the written plans iteratively. Anonymised individual online staff surveys tracked learning. The primary outcome was system safety and latent errors identified from group debriefs. The secondary outcomes were the proportion of completed surveys, confirmation of reporting location, and respective roles for mass casualty incidents. RESULTS: Seven simulation exercises involving more than 700 staff and multidisciplinary responses were completed with debriefs. Usual emergency care was not affected by simulations. Each simulation identified latent errors and system safety issues, including overly complex processes, utilisation of space, and the need for clarifying roles. After the second whole hospital simulation, participants were more likely to return completed surveys (odds ratio=2.7; 95% confidence interval [CI], 1.7-4.3). Repeated exercises resulted in respondents being more likely to know where to report (odds ratio=4.3; 95% CI, 2.5-7.3) and their respective roles (odds ratio=3.7; 95% CI, 2.2-6.1) after a simulated mass casualty incident was declared. CONCLUSION: Simulation exercises are a useful tool to improve mass casualty incident plans iteratively and continuously through hospital-wide engagement of staff.

OBJECTIVE: The aim of this study was to identify the effects of recent innovations in trauma major hemorrhage management on outcome and transfusion practice, and to determine the contemporary timings and patterns of death. BACKGROUND: The last 10 years have seen a research-led change in hemorrhage management to damage control resuscitation (DCR), focused on the prevention and treatment of trauma-induced coagulopathy. METHODS: A 10-year retrospective analysis of prospectively collected data of trauma patients who activated the Major Trauma Centre's major hemorrhage protocol (MHP) and received at least 1 unit of red blood cell transfusions (RBC). RESULTS: A total of 1169 trauma patients activated the MHP and received at least 1 unit of RBC, with similar injury and admission physiology characteristics over the decade. Overall mortality declined from 45% in 2008 to 27% in 2017, whereas median RBC transfusion rates dropped from 12 to 4 units (massive transfusion rates from 68% to 24%). The proportion of deaths within 24âhours halved (33%-16%), principally with a fall in mortality between 3 and 24âhours (30%-6%). Survivors are now more likely to be discharged to their own home (57%-73%). Exsanguination is still the principal cause of early deaths, and the mortality associated with massive transfusion remains high (48%). Late deaths are now split between those due to traumatic brain injury (52%) and multiple organ dysfunction (45%). CONCLUSIONS: There have been remarkable reductions in mortality after major trauma hemorrhage in recent years. Mortality rates continue to be high and there remain important opportunities for further improvements in these patients.

Background: Injury is a leading health burden in children yet relatively little is reported about the contemporary risks they face. Current national registry data may under-represent the true burden of injury to children. We aim to analyse contemporary patterns of paediatric trauma and identify current factors putting children at risk of injury. Methods: A 3-month prospective multicentre cohort evaluation of injured children across the London Major Trauma System was performed. All children receiving a trauma team activation; meeting National Institute for Health and Care Excellence CT head criteria; or admitted/transferred out due to trauma were included. Data were collected on demographics, mechanism and location of injury, and body region injured. The primary outcome was in-hospital mortality and secondary outcome was safeguarding concerns. Results: 659 children were included. Young children were more likely to be injured at home (0-5 years old: 70.8%, n=167 vs adolescents: 15.6%, n=31). Adolescents were more likely to be injured in the street (42.7%, n=85). Head trauma caused over half of injuries in 0-5 years old (51.9%, n=121). Falls were common and increasingly prevalent in younger children, causing 56.6% (n=372) of injuries. In adolescents, penetrating violence caused more than one in five injuries (21.9%, n=50). Most injured children survived (99.8%, n=658), however, one in four (26.1%, n=172) had safeguarding concerns and a quarter of adolescents had police, third sector or external agency involvement (23.2%, n=53). Conclusions: This study describes modern-day paediatric trauma and highlights the variance in injury patterns in young children and adolescents. Importantly, it highlights differences in actual rates of injuries compared with those reported from current national registry data. We must understand real risks facing 21st century children to effectively safeguard future generations. The results provide an opportunity to reassess the current approach to injury prevention, child and adolescent safeguarding, and public health campaigns for child safety.

Head injury is the largest cause of mortality in paediatric trauma. Infants (<1 year old) are a high-risk group and vulnerable to non-accidental injury. A single-centre retrospective study at a major trauma centre collected data on infants presenting with a head injury over a 48-month period. 1127 infants presented with a head injury. 135 CT heads were performed. 38% of scans showed intracranial pathology. The decision about which infants to send for CT scans remains complex. Liberal use risks over-exposure to ionising radiation while restrictive use may miss subtler injuries.
RESUMEN
OBJECTIVES: Hospitals have the responsibility of creating, testing and maintaining major incident (MI) plans. Plans emphasise readiness for acceptance of casualties, though often they neglect discharge planning and care for existing inpatients to make room for the sudden influx.After collaboration and design of a discharge policy for a paediatric MI, we aimed to establish the number of beds made available (primary outcome) to assess potential surge and patient flow. We hypothesised that prompt patient discharge would improve overall departmental flow. Flow is vital for sick patients awaiting admission, for those requiring theatre and also to keep the emergency department clear for ongoing admissions. METHOD AND SETTING: A simulated MI was declared at a London major trauma centre. Five paediatric priority 1 and 15 priority 2 and priority 3 patients were admitted. Using live bed boards, staff initiated discharge plans, and audits were conducted based on hospital bed occupancy and discharge capacity. The patients identified as dischargable were identified and folllowed up for 7 days. RESULTS: Twenty-nine ward beds were created (42% of the total capacity). Handwritten summaries just took 13.3% of the time that electronic summaries took for the same patients by the same doctor. In-hospital transfers allowed five critically injured children into paediatric intensive care unit (PICU), and creation of a satellite PICU allowed for an additional six more if needed. CONCLUSION: We increased level 3 capacity threefold and created 40% extra capacity for ward patients. A formalised plan helped with speed and efficiency of safe discharge during an MI. Carbon copy handwritten discharge letters allowed tracking and saved time. Robust follow-up procedures must be in place for any patients discharged.

This article was migrated. The article was marked as recommended. In light of the recent terrorist attacks in London and Manchester we wanted to test our Major Incident protocol for Paediatrics using simulation. A hospital wide MI Sim was completed in January but focusing on admission pathways, flow and theatre. As a follow up exercise, we wanted to test discharge pathways and our immediate bed capacity in PICU and paediatrics, allowing us to, assess immediate capacity, estimate discharge numbers, test communication pathways, staff responces and next shift planning as well as identifying issues allowing us to improve our major incident policy.
RESUMEN
OBJECTIVES: To describe the epidemiology of assaults resulting in stab injuries among young people. We hypothesised that there are specific patterns and risk factors for injury in different age groups. DESIGN: Eleven-year retrospective cohort study. SETTING: Urban major trauma centre in the UK. PARTICIPANTS: 1824 patients under the age of 25 years presenting to hospital after a stab injury resulting from assault. OUTCOMES: Incident timings and locations were obtained from ambulance service records and triangulated with prospectively collected demographic and injury characteristics recorded in our hospital trauma registry. We used geospatial mapping of individual incidents to investigate the relationships between demographic characteristics and incident timing and location. RESULTS: The majority of stabbings occurred in males from deprived communities, with a sharp increase in incidence between the ages of 14 and 18 years. With increasing age, injuries occurred progressively later in the day (r2=0.66, p<0.01) and were less frequent within 5 km of home (r2=0.59, p<0.01). Among children (age <16), a significant peak in injuries occurred between 16:00 and 18:00 hours, accounting for 22% (38/172) of injuries in this group compared with 11% (182/1652) of injuries in young adults. In children, stabbings occurred earlier on school days (hours from 08:00: 11.1 vs non-school day 13.7, p<0.01) and a greater proportion were within 5 km of home (90% vs non-school day 74%, p=0.02). Mapping individual incidents demonstrated that the spike in frequency in the late afternoon and early evening was attributable to incidents occurring on school days and close to home. CONCLUSIONS: Age, gender and deprivation status are potent influences on the risk of violent injury in young people. Stab injuries occur in characteristic temporal and geographical patterns according to age group, with the immediate after-school period associated with a spike in incident frequency in children. This represents an opportunity for targeted prevention strategies in this population.
