Objective: This study explored the perspectives and behaviours of emergency physicians (EPs), regularly involved in resuscitation, to identify the sources and effects of any stress experienced during a resuscitation as well as the strategies employed to deal with these stressors.Methods: This was a two-centre sequential exploratory mixed-methods study of EPs consisting of a focus group, exploring the human factors related to resuscitation, and an anonymous survey. Between April and June 2020, the online survey was distributed to all EPs working at Australia's largest two major trauma centres, both in Melbourne, and investigated sources of stress during resuscitation, impact of stress on performance, mitigation strategies used, impact of the COVID-19 pandemic on stress and stress management training received. Associations with gender and years of clinical practice were also examined.Results: 7 EPs took part in the focus group and 82 responses to the online survey were received (81% response rate). The most common sources of stress reported were resuscitation of an 'unwell young paediatric patient' (81%, 95% CI 70.6 to 87.6) or 'unwell pregnant patient' (71%, 95% CI 60.1 to 79.5) and 'conflict with a team member' (71%, 95% CI 60.1 to 79.5). The most frequently reported strategies to mitigate stress were 'verbalising a plan to the team' (84%, 95% CI 74.7 to 90.5), 'implementing a standardised/structured approach' (73%, 95% CI 62.7 to 81.6) and 'asking for help' (57%, 95% CI 46.5 to 67.5). 79% (95% CI 69.3 to 86.6) of EPs reported that they would like additional training on stress management. Junior EPs more frequently reported the use of 'mental rehearsal' to mitigate stress during a resuscitation (62% vs 22%; p<0.01) while female EPs reported 'asking for help' as a mitigator of stress more frequently than male EPs (79% vs 47%; p=0.01).Conclusions: Stress is commonly experienced by EPs during resuscitation and can impact decision-making and procedural performance. This study identifies the most common sources of stress during a resuscitation as well as the strategies that EPs use to mitigate the effects of stress on their performance. These findings may contribute to the development of tailored stress management training for critical care clinicians. [ABSTRACT FROM AUTHOR]

Background: Endotracheal intubation (ETI) is a commonly performed but potentially high-risk procedure in the emergency department (ED). Requiring more than one attempt at intubation has been shown to increase adverse events and interventions improving first-attempt success rate should be identified to make ETI in the ED safer. We introduced and examined the effect of a targeted bundle of airway initiatives on first-attempt success and adverse events associated with ETI.Methods: This prospective, interventional cohort study was conducted over a 2-year period at an Australian Major Trauma Centre. An online airway registry was established at the inception of the study to collect information related to all intubations. After 6 months, we introduced a bundle of initiatives including monthly audit, monthly airway management education and an airway management checklist. A time series analysis model was used to compare standard practice (ie, first 6 months) to the postintervention period.Results: There were 526 patients, 369 in the intervention group and 157 in the preintervention comparator group. A total of 573 intubation attempts were performed. There was a significant improvement in first-attempt success rates between preintervention and postintervention groups (88.5% vs 94.6%, relative risk 1.07; 95% CI 1.00 to 1.14, p=0.014). After the introduction of the intervention the first-attempt success rate increased significantly, by 13.4% (p=0.006) in the first month, followed by a significant increase in the monthly trend (relative to the preintervention trend) of 1.71% (p<0.001). The rate of adverse events were similar preintervention and postintervention (hypoxia 8.3% vs 8.9% (p=0.81); hypotension 8.3% vs 7.0% (p=0.62); any complication 27.4% vs 23.6% (p=0.35)).Conclusions: This bundle of airway management initiatives was associated with significant improvement in the first-attempt success rate of ETI. The introduction of a regular education programme based on the audit of a dedicated airway registry, combined with a periprocedure checklist is a worthwhile ED quality improvement initiative.

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

Introduction: An increasing proportion of the major trauma population are older persons. The pattern of injury is different in this age group and serious chest injuries represent a significant subgroup, with implications for trauma system design. The aim of this study was to examine trends in thoracic injuries among major trauma patients in an inclusive trauma system.Methods: This was a retrospective review of all adult cases of major trauma with thoracic injuries of Abbreviated Injury Scale score of 3 or more, using data from the Victorian State Trauma Registry from 2007 to 2016. Prevalence and pattern of thoracic injury was compared between patients with multitrauma and patients with isolated thoracic injury. Poisson regression was used to determine whether population-based incidence had changed over the study period.Results: There were 8805 cases of hospitalised major trauma with serious thoracic injuries. Over a 10-year period, the population-adjusted incidence of thoracic injury increased by 8% per year (incidence rate ratio [IRR] 1.08, 95% CI 1.07 to 1.09). This trend was observed across all age groups and mechanisms of injury. The greatest increase in incidence of thoracic injuries, 14% per year, was observed in people aged 85 years and older (IRR 1.14, 95% CI 1.09 to 1.18).Conclusions: Admissions for thoracic injuries in the major trauma population are increasing. Older patients are contributing to an increase in major thoracic trauma. This is likely to have important implications for trauma system design, as well as morbidity, mortality and use of healthcare resources. [ABSTRACT FROM AUTHOR]

Background: Blunt thoracic aortic injury (BTAI) is an uncommon diagnosis, usually developing as a consequence of high-impact acceleration-deceleration mechanisms. Timely diagnosis may enable early resuscitation and reduction of shear forces, essential to prevent worsening of the injury prior to definitive management. Death is commonly due to haemorrhagic shock, but clinical features may be absent until sudden and massive haemorrhage.Objectives: The aim of this systematic review was to determine the proportion of patients with BTAI who present with unstable vital signs.Methods: Manuscripts were identified through a search of MEDLINE, EMBASE and the Cochrane Library databases, focusing on subject headings and keywords related to the aorta and trauma. Mechanisms of injury, haemodynamic status and mortality from the included manuscripts were reviewed. Meta-analysis of presenting haemodynamic status among a select group of similar papers was conducted.Results: Nineteen studies were included, with five selected for meta-analysis. Most reported cases of BTAI (80.0%-100%) were caused by road traffic incidents, with mortality consistently higher among initially unstable patients. There was statistically significant heterogeneity among the included studies (P<0.01). The pooled proportion of patients with haemodynamic instability in the setting of BTAI was 48.8% (95% CI 8.3 to 89.4).Conclusions: Normal vital signs do not rule out aortic injury. A high degree of clinical suspicion and liberal use of imaging is necessary to prevent missed or delayed diagnoses. [ABSTRACT FROM AUTHOR]

Introduction Prehospital notification of injured patients enables prompt and timely care in hospital through adequate preparation of trauma teams, space, equipment and consumables necessary for resuscitation, and may improve outcomes. In India, anecdotal reports suggest that prehospital notification, in those few places where it occurs, is unstructured and not linked to a well-defined hospital response. The aim of this manuscript is to describe, in detail, a study protocol for the evaluation of a formalised approach to prehospital notification. Methods and analysis This is a longitudinal prospective cohort study of injured patients being transported by ambulance to major trauma centres in India. In the preintervention phase, prospective data on patients will be collected on prehospital assessment, notification, inhospital assessment, management and outcomes and recorded in a new tailored multihospital trauma registry. All injured patients arriving by ambulance and allocated to a red or yellow priority category will be eligible for inclusion. The intervention will be a prehospital notification application to be used by ambulance clinicians to notify emergency departments of the impending arrival of a patient. The proportion of eligible patients arriving to hospital after notification will be the primary outcome measure. Secondary outcomes evaluated will be availability of a trauma cubicle, presence of a trauma team on patient arrival, time to first chest X-ray and inhospital mortality. Progress Ethical approval has been obtained from the All India Institute of Medical Sciences, New Delhi and sitespecific approval granted by relevant trauma services. The trial has also been registered with the Monash University Human Research and Ethics Committee; Project number: CF16/1814 - 2016000929. Results will be fed back to prehospital and hospital clinicians via a series of reports and presentations. These will be used to facilitate discussions about service redesign and implementation. It is expected that evidence for improved outcomes will enable widespread adoption of this intervention among centres in all settings with less established tools for prehospital assessment and notification.

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

Background Traumatic injury is a leading contributor to the overall global burden of disease. However, there is a worldwide shortage of population data to inform understanding of non-fatal injury burden. An improved understanding of the pattern of recovery following trauma is needed to better estimate the burden of injury, guide provision of rehabilitation services and care to injured people, and inform guidelines for the monitoring and evaluation of disability outcomes. Objective To provide a comprehensive overview of patient outcomes and experiences in the first 5 years after serious injury. Design This is a population-based, nested prospective cohort study using quantitative data methods, supplemented by a qualitative study of a seriously injured participant sample. Participants All 2547 paediatric and adult major trauma patients captured by the Victorian State Trauma Registry with a date of injury from 1 July 2011 to 30 June 2012 who survived to hospital discharge and did not opt-off from the registry. Analysis To analyse the quantitative data and identify factors that predict poor or good outcome, whether there is change over time, differences in rates of recovery and change between key participant subgroups, multilevel mixed effects regression models will be fitted. To analyse the qualitative data, thematic analysis will be used to identify important themes and the relationships between themes. Contribution to the field The results of this project have the potential to inform clinical decisions and public health policy, which can reduce the burden of non-fatal injury and improve the lives of people living with the consequences of severe injury.

INTRODUCTION: Improved early pain control may affect the longer-term prevalence of persistent pain. In a previous randomised, controlled trial, we found that the administration of ketamine on hospital arrival decreased pain scores to a greater extent than morphine alone in patients with prehospital traumatic pain. In this follow-up study, we sought to determine the prevalence of persistent pain and whether there were differences in patients who received ketamine or morphine. METHODS: This study was a long-term follow-up study of the prehospital, prospective, randomised, controlled, open-label study comparing ketamine with morphine in patients with trauma and a verbal pain score of >5 after 5mg intravenous morphine. Patients were followed-up by telephone 6-12months after enrolment, and a questionnaire including the SF-36 (V.2) health-related quality of life survey and the Verbal Numerical Rating Scale for pain was administered. RESULTS: A total of 97/135 (72%) patients were able to be followed-up 6-12 months after enrolment between July 2008 and July 2010. Overall, 44/97 (45%) participants reported persistent pain related to their injury, with 3/97 (3%) reporting persistent severe pain. The prevalence of persistent pain was the same between study groups (22/50 (44%) for the ketamine group vs 22/47 (46%) for the morphine group). There was no difference in the SF-36 scores between study arms. CONCLUSIONS: There is a high incidence of persistent pain after traumatic injury, even in patients with relatively minor severity of injury. Although decreased pain scores at hospital arrival are achieved with ketamine compared with morphine, this difference does not affect the prevalence of persistent pain or health-related quality of life 6months after injury. Further larger studies are required to confirm this finding. TRIAL REGISTRATION NUMBER: Australian and New Zealand Clinical Trials Registry (ACTRN12607000441415). [ABSTRACT FROM AUTHOR]

Introduction The aim of this study was to test the hypothesis that all blunt trauma patients, presenting with a Glasgow coma scale (GCS) score of 15, without intoxication or neurological deficit, and no pain or tenderness on log-roll can have any thoracolumbar fracture excluded without imaging. Materials and Methods All patients diagnosed with a thoracolumbar fracture presenting to the emergency department of a major trauma centre and having an initial GCS score of 15 were included in the study. Variables collected included type of fracture, mechanism of injury, the presence of pain or tenderness on log-roll, ethanol levels and prehospital opioid analgesia. Results There were 536 patients with thoracolumbar fractures, of which 508 (94.8%) patients had either pain, tenderness or had received prehospital opioid analgesia. A small subgroup of 28 (5.2%) patients who received no prehospital opioid analgesia, did not complain of pain and had no tenderness to the thoracolumbar spine elicited on log-roll. This subgroup was significantly older (p=0.033) and a high proportion of patients (64.3%) had a concurrent fracture of the cervical spine. Within this subgroup, a clinically significant unstable thoracic fracture was present in three patients, with all three patients exhibiting symptoms and signs of neurological injury or having a concurrent cervical vertebral fracture. Conclusions In this population of blunt trauma patients with a GCS score of 15, not under the influence of alcohol or prehospital morphine administration, the absence of pain or tenderness on log-roll can exclude a clinically significant lumbar vertebral fracture, but does not exclude a thoracic fracture.

Introduction Injured patients presenting with hypothermia, acidosis and coagulopathy have been identified at high risk of death. This study aimed to describe the presentation, management and outcome of major trauma patients presenting with the 'triad of death' and identify ways to improve survival. Methods A retrospective, explicit chart review was undertaken on patients presenting to a level I adult major trauma centre with the 'triad of death'. These patients presented directly from the scene, were coagulopathic (international normalised ratio (INR) >1.5), hypothermic (temperature <35°C) and acidotic (pH <7.2) on arrival. Results There were 90 patients over an 8-year period, with an overall mortality of 47.8%. No significant differences were observed among demographics and injury severity scores between survivors and nonsurvivors. Extremes of systolic blood pressure and heart rate, a high activated partial thromboplastin time activated partial thromboplastin time, low fibrinogen counts, pH, bicarbonate, base excess and haemoglobin were present among survivors. There were no survivors in our cohort with an initial INR greater than 3.2. Survivors received significantly lower volumes of packed red blood cells. Conclusions There has been little change in mortality over time in this subgroup of major trauma patients. While the presence of the triad alone does not determine futility, there were no survivors over 8 years with extreme coagulopathy with concurrent hypothermia and acidosis. [ABSTRACT FROM AUTHOR]

Aetiology/risk factors Most people with asthma are atopic; exposure to certain stimuli initiates inflammation and structural changes in airways, causing airway hyperresponsiveness and variable airflow obstruction, which in turn cause most asthma symptoms. Stimuli include environmental allergens, occupational sensitising agents, and respiratory viral infections. Prognosis About 10.20% of people presenting to the emergency department with asthma are admitted to hospital. Of these, fewer than 10% receive mechanical ventilation, although previous ventilation is associated with a 19-fold increased risk of ventilation for a subsequent episode. It is unusual for people to die unless they have had respiratory arrest before reaching hospital. One prospective study of 939 people discharged from emergency care found that 17% (95% confidence interval 14% to 20%) had relapsed by two weeks. Aims To minimise or eliminate symptoms; to maximise lung function; to prevent exacerbations; to minimise the need for medication; to minimise adverse effects of treatment; and to provide enough information and support to facilitate self management of asthma. Outcomes Symptoms (daytime and nocturnal); lung function (PEFR and forced expiratory volume in one second (FEV1)); need for rescue medication such as inhaled beta 2 agonists; variability of flow rates; activities of daily living; adverse effects of treatment.

Background Clinical handover between paramedics and the trauma team is undertaken in a time-pressured environment. Paramedics are often required to handover complex problems to a multitude of staff. There is evidence that information loss occurs at this transition. The aims of this project were to (1) develop a minimum dataset to assist paramedics provide handover; (2) identify attributes of effective and ineffective handover; (3) determine the feasibility of advanced data transmission; and (4) identify how to best display data in trauma bays. Methods Qualitative study of paramedics and trauma team members. A thematic analysis was undertaken using grounded theory. Results Ten paramedics and 17 trauma team members were interviewed. A minimum dataset modified on an existing template was developed to include fields required by the trauma team to inform immediate treatment. Respondents stated that an effective handover was one which was delivered succinctly and in a structured manner, and contained only vital data necessary to direct immediate treatment. Advanced transmission of data to the receiving hospital was widely supported. While computers carried by paramedics were capable of exporting data to the receiving hospital, barriers such as time constraints, workflow issues and infection control issues impeded the ability to do this in the current environment. Discussion There is support for the adoption and further evaluation of a handover template. It can provide valuable structure to the face-to-face handover, and experience from other specialties suggests it can reduce information loss. Strategies to enable information to be transmitted in advance of the patients' arrival must address concerns voiced by paramedics. [ABSTRACT FROM PUBLISHER]
