Introduction: The aim of this systematic review was to investigate whether viscoelastic haemostatic assays (VHAs) offer comparative diagnostic ability of acute traumatic coagulopathy (ATC) compared to the standard laboratory coagulation tests (SLCT). ATC is a complication of major trauma characterized by dysfunctional blood clotting, leading to an increased bleeding risk. Additionally, we aimed to analyse the association of VHA with blood product use and health outcomes. Methods: The search protocol was pre-published and completed on December 2, 2020, assessing manuscripts from 2000 until the present. We searched MEDLINE, Embase, Cochrane Central, BIOSIS, Emcare, CINAHL, and additional online resources and referenced lists. Included were manuscripts that quantitatively reported the detection of ATC using VHAs and SLCTs. A meta-analysis was undertaken including observational studies that reported on patients with injuries to all body regions and results analysed using a random-effects model and reported using pooled odds ratio with 95% confidence intervals (CI). Results: There were 14 observational studies and one randomized control trial involving 2,715 participants that satisfied inclusion criteria. We observed significant heterogeneity in the definitions of ATC, study design, setting, and patient population. Among observational studies that reported on patients with injuries to all body regions, VHAs were associated with higher odds of diagnosing ATC compared to SLCT (pooled OR 2.4; 95% CI: 1.4–4.1). There was inadequate evidence to suggest VHAs were associated with reduced blood product usage or lower mortality. Conclusion: VHAs detected more patients with ATC compared to SLCTs. However, the clinical significance and applicability of this finding remains unknown as translation to management was not adequately reported.

Haemorrhagic shock after trauma is a leading cause of death worldwide, particularly in young individuals. Despite advances in trauma systems and resuscitation strategies, mortality from haemorrhagic shock has not declined over the previous two decades. A proportion of shocked trauma patients may experience a deficiency of cortisol relative to the severity of their injury. The benefit of exogenous steroid administration in patients suffering haemorrhagic shock as a result of injury is unclear. A systematic review of four databases (Ovid Medline, Ovid Embase, Cochrane, Scopus) was undertaken. Inclusion and exclusion criteria were pre-determined and two reviewers independently screened the articles with disagreements arbitrated by a third reviewer. The primary outcome variable was 28-day mortality. Quality of studies were assessed using the Cochrane-risk-of-bias (RoB 2) tool. Of the 2919 studies yielded by the search strategy, 1274 duplicates were removed and 1645 screened on title and abstract. After the full text of 33 studies were assessed, two articles were included. Both studies were over 30 years old with small numbers of participants and with primary outcomes not including mortality. Of the data available, no statistically significant difference in mortality was detected. Hospital length of stay, reversal of shock or adverse events were not reported. Both studies were at risk of bias. There are no high quality or recent studies in the English literature investigating the use of steroids for haemorrhagic shocked trauma patients.

The present study aimed to determine the difference in force required to puncture simulated pleura comparing Kelly clamps to fine artery forceps. The treatment of symptomatic traumatic pneumothorax and haemothorax involves puncture of the parietal pleura to allow decompression. This is usually performed using Kelly clamps or fine artery forceps. Over-puncture pulmonary injury risk increases with the force used.An experienced single operator performed puncturing of simulated parietal pleura on a thoracic mannequin while wearing a force sensor under gloves. The force imparted at the device tip onto the parietal pleura was estimated by subtracting the force required to hold the device from the total force. Outcome variables were the total maximum force and force imparted by the device.There were 11 simulated procedures completed, seven using Kelly clamps and four using fine artery forceps. After subtracting the force required to hold the chosen forceps, the median value of pleural puncture force using Kelly clamps was 52.91 N (IQR 36.68-63.56) and 10.70 N (IQR 7.64-26.56) using fine artery forceps (P = 0.006).A significantly increased force was required to puncture simulated parietal pleura using Kelly clamps compared to fine artery forceps. This higher puncture force will be associated with increased instrument acceleration at the time of pleural puncture, which may result in an increased risk of injury to the underlying lung. Based on these data, clinicians may reduce the risk of pulmonary injury by using fine artery forceps rather than Kelly clamps when performing pleural decompression.

Video surveillance and detection of players with visible signs of concussion by experienced medical staff facilitates rapid on-field screening of suspected concussion in professional sports. This method, however has not been validated in community sports where video footage is unavailable. This study aimed to explore the utility of visible signs of concussion to identify players with decrements in performance on concussion screening measures. In this observational prospective cohort study, personnel with basic training observed live matches across a season (60 matches) of community male and female Australian football for signs of concussion outlined in the community-based Head Injury Assessment form (HIAf). Players identified to have positive signs of concussion (CoSign+) following an impact were compared with players without signs (CoSign-). Outcome measures, the Sport Concussion Assessment Tool (SCAT3) and Cogstate, were administered at baseline and post-match. CoSign+ (

Supported by the state government, three health networks partnered to initiate a virtual ED (VED), as part of a broader roll-out of emergency telehealth services in Victoria. The aim of the present study (Southeast Region Virtual Emergency Department-1 [SERVED-1]) was to report the initial 5-month experience and included all patients assessed through the service over the first 5 months (1 February 2022 to 30 June 2022).VED consults occurred after referral from paramedics in the pre-hospital setting. Electronic medical records were retrospectively reviewed for demographic, presenting complaint and outcome data. The primary outcome was the count of VED consultations. The secondary outcome was the proportion of patients where physical ED attendance was avoided within 72 h. The proportion of physical ED attendances avoided sub-grouped by primary presenting complaints were reported.There were 1748 patients who had a VED consultation, of which 1261 (72.1%; 95% confidence interval [CI] 70.0-74.2) patients had physical presentation to an ED avoided in the 72 h following the consult. There was a significant increase in consultations over the 5-month period (incidence rate ratio 1.27; 95% CI 1.23-1.31, P 0.001) that was consistent in the three health services. The most common presenting complaints were COVID-19 and shortness of breath, and physical presentation was avoided most often among younger patients and those with COVID-19.Initial experience demonstrated a significant increase in adoption of the service and an overall avoidance of physical ED attendance by a majority of patients. These results support ongoing VED consultations, complemented by follow up and health economic evaluations.

BACKGROUND There is a lack of consensus regarding the role of investigations among patients presenting to the emergency department (ED) with recurrent seizures. The aim of this systematic review was to determine the frequency and utility of commonly requested investigations for nontrauma patients presenting to the ED with recurrent seizures. METHODS The MEDLINE, EMBASE, and Cochrane Library databases were searched (March 2021) for articles on this topic using search terms related to recurrent seizures, investigations, and the ED. The inclusion criteria required that articles include adult nontrauma patients presenting to the ED. Studies exclusively investigating first-episode seizures, trauma patients, and status epilepticus were excluded. Eligible studies were assessed for bias using the Newcastle-Ottawa scale. Results of studies were presented using proportions. RESULTS There were six cohort studies included that contributed data from 36,595 patients. All six studies assessed at least one of our primary outcomes for computed tomography (CT) brain scans. The proportion of patients who underwent a head CT ranged from 13% to 42%. The rates of abnormal head CT findings ranged from 8% to 21%. One study reported on magnetic resonance imaging (MRI) and found it used infrequently in 0.79% of cases. The proportion and yield of nonneuroimaging investigations were not well evaluated in this patient population. Only one study reported on the utility of sodium levels or blood glucose results for this population and reported abnormalities in sodium levels for 19% of patients and abnormalities in glucose levels in 50% of patients. CONCLUSIONS In this population, CT brain scans appeared to be performed uncommonly but with moderate rates of abnormal findings. In the absence of prolonged alteration of consciousness, a history of brain tumor, or positive neurologic findings, however, neuroimaging was of low yield. Given the heterogeneity and potential limitations of these studies, further research on this topic is required.

Inter-hospital transfers are increasingly common due to the regionalisation of healthcare, but are associated with patient discomfort, high costs and adverse events. The aim of the present study was to evaluate the effectiveness of a trauma outreach service for preventing inter-hospital transfers to a major trauma centre.This was an observational pre- and post-intervention study over a 12-month period from 1 October 2020 to 30 September 2021. Eligible patients sustained a fall at Caulfield Hospital, a subacute care hospital specialising in community services, rehabilitation, geriatric medicine and aged mental health. The intervention was delivery of site-specific education at Caulfield Hospital and a trauma outreach service by specialist trauma clinicians at The Alfred Hospital who provided remote assessment, assisted with clinical management decisions and advised on appropriateness of transfer.The present study included 160 patients in the pre-intervention phase and 203 after the intervention. The primary outcome of transfer occurred in 19 (11.9%) patients in the pre-intervention phase and 4 (2.0%) in the post-intervention phase (P 0.001). In the subgroup of patients without pelvis or long bone fractures, pre-intervention transfer occurred for 17 (10.9%) patients and post-intervention transfer occurred for 4 (2.0%) patients (P 0.001). CT imaging was performed for 54 (33.8%) patients in the pre-intervention and 45 (22.2%) patients in the post-intervention group (P = 0.014).Telehealth consultation with a trauma specialist was associated with significant reduction of inter-hospital transfers, and significant reduction of CT imaging. This supports continuation of the service with scope for expansion and evaluation of patient-centred outcomes.

The objectives of the present study were to report the proportion of older teenagers, including the subgroup operating a motor vehicle, presenting to an adult major trauma centre after injury with a positive blood alcohol concentration (BAC) over a 12-year period.This was a registry-based cohort study, including all patients aged 16-19 years presenting to an adult major trauma centre in Victoria, Australia from January 2008 to December 2019 and included in the trauma registry. A Poisson regression model was used to test for change in incidence of positive BAC associated trauma and summarised using incidence rate ratios (IRRs) and 95% confidence intervals (CIs).There were 1658 patients included for analysis and alcohol was detected in 368 (22.2%; 95% CI 20.2-24.3). Most alcohol positive presentations were on weekend days (n = 207; 56.3%) and most were males (n = 307). Over the 12-year period, there was a reduction in the incidence of older teenagers presenting with a positive BAC (IRR 0.95; 95% CI 0.93-0.98; P = 0.001). Among patients presenting after trauma in the setting of operating a motor vehicle (n = 545), alcohol was detected in 80 (14.7%) with no significant change in incidence of positive BAC (IRR 0.95; 95% CI 0.89-1.02; P = 0.17).A substantial proportion of older teenagers included in the registry had alcohol exposure prior to trauma. Despite a modest down-trending incidence, the need for continuing preventive measures is emphasised. In particular, preventive efforts should be targeted at male, older teenagers undertaking drinking activities on weekend days and driving motor vehicles.

Objective: Cognitive symptoms are common in the initial weeks after mTBI, but recovery is generally expected within three months. However, there is limited information about recovery specifically in older age cohorts. Therefore, this study investigated cognitive outcome three months after mTBI in older adults (≥ 65 years) compared to trauma and community age-matched controls and explored risk factors for outcome after traumatic injury. Methods: Older mTBI patients (n = 40) and older adults with mild traumatic injury but without head injury (n = 66) were compared to a noninjured community control group (n = 47). Cognitive assessment included neuropsychological and computerized tests. Group differences were compared on individual tasks and overall cognitive performances using composite scores. Regression analyses identified predictors of outcome for trauma patients and moderator analyses explored possible interactions of mTBI severity with age and cognition. Results: As well as lower performances in processing speed and memory, both trauma groups had significantly lower performance on composite neuropsychological (d = .557 and .670) and computerized tasks (d = .783 and .824) compared to noninjured controls. Age, education, and history of depression were direct predictors of cognitive performance after mild traumatic injury (with or without head injury). Further moderation analysis demonstrated that mTBI severity (Glasgow Coma Scale < 15) moderated the impact of older age on computerized assessment (β = -.138). Conclusions: Three months after mild trauma (regardless of head injury), older people demonstrate lower cognition compared to noninjured peers. However, severity of mTBI (Glasgow Coma Scale < 15) can interact with older age to predict poorer cognitive outcomes.

To assess the feasibility of an ED presenting complaint (PC) tool that categorised all ED PCs into 10 categories.A retrospective analysis of 1445 consecutive patient encounters was conducted. The primary outcome was the frequency of use of the 10 PC categories.Of the 1203 patient encounters meeting inclusion criteria, the PC tool was completed by clinicians in 574 (47.7%). When completed, the tool's 10 options were selected for most presentations (72.3%).The PC tool captured the majority of presenting complaints in 10 categories. External validation is recommended.

Traumatic brain injury (TBI) is the largest contributor to death and disability in people who have experienced physical trauma. There are no national data on outcomes for people with moderate to severe TBI in Australia.To determine the incidence and key determinants of outcomes for patients with moderate to severe TBI, both for Australia and for selected population subgroups, including Aboriginal and Torres Strait Islander Australians.The Australian Traumatic Brain Injury National Data (ATBIND) project will analyse Australia New Zealand Trauma Registry (ATR) data and National Coronial Information Service (NCIS) deaths data. The ATR documents the demographic characteristics, injury event description and severity, processes of care, and outcomes for people with major injury, including TBI, assessed and managed at the 27 major trauma services in Australia. We will include data for people with moderate to severe TBI (Abbreviated Injury Scale [AIS] (head) score higher than 2) who had Injury Severity Scores [ISS] higher than 12 or who died in hospital. People will also be included if they died before reaching a major trauma service and the coronial report details were consistent with moderate to severe TBI. The primary research outcome will be survival to discharge. Secondary outcomes will be hospital discharge destination, hospital length of stay, ventilator-free days, and health service cost.The Alfred Ethics Committee approved ATR data extraction (project reference number 670/21). Further ethics approval has been sought from the NCIS and multiple Aboriginal health research ethics committees. The ATBIND project will conform with Indigenous data sovereignty principles.Our findings will be disseminated by project partners with the aim of informing improvements in equitable system-level care for all people in Australia with moderate to severe TBI.Not applicable.

Objective: The aim of the present study was to describe the epidemiology and clinical features of patients presenting to the ED with suspected and confirmed COVID-19 during Australia's 'second wave'. Methods: The COVID-19 ED (COVED) Project is an ongoing prospective cohort study in Australian EDs. This analysis presents data from 12 sites across four Australian states for the period from 1 July to 31 August 2020. All adult patients who met the criteria for 'suspected COVID-19' and underwent testing for SARS-CoV-2 in the ED were eligible for inclusion. Study outcomes included a positive SARS-CoV-2 test result, mechanical ventilation and in-hospital mortality. Results: There were 106 136 presentations to the participating EDs and 12 055 (11.4%; 95% confidence interval [CI] 11.2-11.6) underwent testing for SARS-CoV-2. Of these, 255 (2%) patients returned a positive result. Among positive cases, 13 (5%) received mechanical ventilation during their hospital admission compared to 122 (2%) of the SARS-CoV-2 negative patients (odds ratio 2.7; 95% CI 1.5-4.9, P = 0.001). Nineteen (7%) SARS-CoV-2 positive patients died in hospital compared to 212 (3%) of the SARS-CoV-2 negative patients (odds ratio 2.3; 95% CI 1.4-3.7, P = 0.001). Strong clinical predictors of the SARS-CoV-2 test result included self-reported fever, sore throat, bilateral infiltrates on chest X-ray, and absence of a leucocytosis on first ED blood tests (P Conclusions: In this prospective multi-site study during Australia's 'second wave', a substantial proportion of ED presentations required SARS-CoV-2 testing and isolation. Presence of SARS-CoV-2 on nasopharyngeal swab was associated with an increase in the odds of death and mechanical ventilation in hospital.

Inconsistency in the structure and function of team-based major trauma reception and resuscitation is common. A standardised trauma team training programme was initiated to improve quality and consistency among trauma teams across a large, mature trauma system. The aim of this manuscript is to outline the programme and report on the initial perception of participants.The Alfred Trauma Team Reception and Resuscitation Training (TTRRT) programme commenced in March 2019. Participants included critical care and surgical craft group members commonly involved in trauma teams. Training was site-specific and included rural, urban and tertiary referral centres. The programme consisted of prescribed pre-learning, didactic lectures, skill stations and simulated team-based scenarios. Participant perceptions of the programme were collected before and after the programme for analysis.The TTRRT was delivered to 252 participants and 120 responses were received. Significant improvement in participant-reported confidence was identified across all key topic areas. There was also a significant increase in both confidence and clinical exposure to trauma team leadership roles after participation in the programme (from 53 [44.2%] to 74 [61.7%; P = 0.007]). This finding was independent of clinician experience.A team-based trauma reception and resuscitation education programme, introduced in a large, mature trauma system led to positive participant-reported outcomes in clinical confidence and real-life team leadership participation. Wider implementation combined with longitudinal data collection will facilitate correlation with patient and staff-centred outcomes.

OBJECTIVE The objective was to evaluate the effectiveness of methoxyflurane versus standard care for the initial management of severe pain among adult emergency department (ED) patients. METHODS This randomized parallel-group open-label phase IV trial of methoxyflurane was conducted in a tertiary hospital ED setting in Australia. Inclusion criteria required adult patients to have an initial pain score ≥ 8 on the 11-point Numerical Rating Scale (NRS). Patients were randomized 1:1 to receive either inhaled methoxyflurane (3 mL) or standard analgesic treatment at ED triage. The primary outcome was the proportion of patients achieving clinically substantial pain reduction, defined as a ≥50% drop in the pain score at 30 minutes. Secondary outcomes included the pain score at multiple time points (15, 30, 60, 90 minutes) and the difference in the proportion of patients achieving a >2-point reduction on the NRS. RESULTS There were 120 patients randomized and analyzed between September 4, 2019, and January 16, 2020. The primary outcome was achieved in six (10%) patients in the methoxyflurane arm and three (5%) in the standard care arm (p = 0.49). A higher proportion of patients in the methoxyflurane arm reported a >2-point drop on the NRS at all time points (17% vs. 5% at 15 minutes, 25% vs. 9% at 30 minutes, 30% vs. 10% at 60 minutes, and 33% vs. 13% at 90 minutes). Methoxyflurane use was also associated with lower median pain scores at all time points. CONCLUSION Initial management with inhaled methoxyflurane in the ED did not achieve the prespecified substantial reduction in pain, but was associated with clinically significant lower pain scores compared to standard therapy.

Objective: The aim of the present study was to describe the epidemiology and clinical features of patients presenting to the ED with suspected and confirmed COVID‐19. Methods: The COVID‐19 ED (COVED) Project is an ongoing prospective cohort study in Australian EDs. This analysis presents data from eight sites across Victoria and Tasmania for July 2020 (during Australia's ‘second wave’). All adult patients who met criteria for ‘suspected COVID‐19’ and underwent testing for SARS‐CoV‐2 in the ED were eligible for inclusion. Study outcomes included a positive SARS‐CoV‐2 test result and mechanical ventilation. Results: In the period 1 July to 31 July 2020, there were 30 378 presentations to the participating EDs and 2917 (9.6%; 95% confidence interval 9.3–9.9) underwent testing for SARS‐CoV‐2. Of these, 50 (2%) patients returned a positive result. Among positive cases, two (4%) received mechanical ventilation during their hospital admission compared to 45 (2%) of the SARS‐CoV‐2 negative patients (odds ratio 1.7, 95% confidence interval 0.4–7.3; P = 0.47). Two (4%) SARS‐CoV‐2 positive patients died in hospital compared to 46 (2%) of the SARS‐CoV‐2 negative patients (odds ratio 1.7, 95% confidence interval 0.4–7.1; P = 0.49). Strong clinical predictors of a positive SARS‐CoV‐2 result included self‐reported fever, non‐smoking status, bilateral infiltrates on chest X‐ray and absence of a leucocytosis on first ED blood tests (P Conclusion: In this prospective multi‐site study from July 2020, a substantial proportion of ED patients required SARS‐CoV‐2 testing, isolation and enhanced infection prevention and control precautions. Presence of SARS‐CoV‐2 on nasopharyngeal swab was not associated with death or mechanical ventilation.

Blunt vertebral artery injury (VAI) is associated with severe cervicocephalic trauma and may have devastating consequences. This study aimed to determine the incidence and nature of VAI in polytrauma patients. The secondary objective was to assess the association of VAI with previously suggested risk factors. It was a retrospective observational study of all polytrauma patients admitted to the trauma unit between April 2018 and July 2019, who had CT neck angiography to diagnose blunt VAI according to modified Denver criteria. Out of 1084 admitted polytrauma patients, 1025 (94.6%) sustained blunt trauma. Of these, 120 (11.7%) underwent screening CT neck angiography. VAI was detected in 10 (8.3%; 95% CI 4.1–14.8) patients. There were three patients with Grade I injury, two with Grade II, and five with Grade IV injury. Among all trauma admissions, the incidence of diagnosed VAI was 0.9% (95% CI 0.5–1.8). Among patients suspected of VAI, there was no univariable association of VAI with C-Spine fracture: OR 4.2 (95% CI 0.51–34.4; p = 0.18). There were two (20%) deaths related to VAI. Traumatic VAI was uncommonly detected in this major trauma service in Saudi Arabia. High suspicion and liberal screening by CT angiography in cases where VAI is possible should be considered to avoid missed injuries.

Objectives To determine if Victorian state of emergency (SOE) measures to combat COVID‐19 were associated with delayed presentations or management of acute stroke and acute myocardial infarction (AMI). Methods This was a retrospective, pre‐ and post‐implementation study using data from an adult, tertiary cardiology and neurosciences centre with 24‐hour capacity for endovascular procedures. All primary presentations with acute stroke or AMI during the first 28 days of Stage 2 and 3 SOE restrictions (26 March to 23 April 2020) were compared to an equivalent period without restrictions (26 March to 23 April 2019). The primary outcome variable was time from onset of symptoms to emergency department (ED) presentation. Results There were 52 (1.6% of all ED presentations) patients that met inclusion criteria during the SOE period and 57 (1.0%) patients in the comparator period. Patients were equally matched for demographics, disease severity and prior history of stroke or AMI. Median time from symptom onset to presentation was 227 (93‐1183) mins during the SOE period and 342 (119‐1220) mins during the comparator period (p=0.24). Among eligible patients with ischaemic stroke or ST‐elevation AMI, median time to primary reperfusion intervention was 65 (37‐78) mins during SOE and 44 (39‐60) mins in the comparator period (p=0.54). There were no differences in mortality at hospital discharge (9.6% vs 10.5%) and hospital LOS (5.4 vs 4.3 days). Conclusions In the first 28 days, SOE measures to combat COVID‐19 were not associated with delays in presentation or life‐saving interventions for patients with acute stroke and AMI.

OBJECTIVE: The number of patients with suspected COVID-19 presenting to Australian EDs continues to impose a burden on healthcare services. Isolation is an important aspect of infection prevention and control, but has been associated with undesirable consequences among hospital inpatients. The aim of the present study was to determine if isolation is associated with an increased length of stay (LOS) in the ED. METHODS: The Registry for Emergency Care Project is a prospective cohort study with a series of nested sub-studies. The present study was a retrospective analysis of adult patients allocated an Australasian Triage Scale category of 1 or 2 who presented to a tertiary ED between 18 and 31 May 2020. The primary outcome was ED LOS. Regression methods were used to determine the independent association between ED isolation and LOS. RESULTS: There were 447 patients who met inclusion criteria, of which 123 (28%) were managed in isolation. The median (interquartile range) ED LOS was 259 (210-377) min for the isolation group and 204 (126-297) min for the non-isolation group, a difference in median ED LOS of 55 min (P < 0.001). Isolation was independently associated with a 23% increase in ED LOS (P = 0.002) and doubled the odds of an ED stay of more than 4 h (adjusted odds ratio 2.2 [1.4-3.4], P = 0.001). CONCLUSION: Consistent with the anecdotal experience of Australian ED clinicians, the present study demonstrated an increased ED LOS for patients managed in isolation. Enhanced infection prevention and control precautions will be required during and beyond the current pandemic, creating significant ongoing challenges for emergency care systems.

OBJECTIVE: The aim of the present study was to describe the epidemiological and clinical features of ED patients with suspected and confirmed COVID-19. METHODS: The COVID-19 Emergency Department (COVED) Project is an ongoing prospective cohort study that includes all adult patients presenting to The Alfred Hospital ED who undergo testing for SARS-CoV-2. Current guidelines recommend testing for patients with fevers or chills, acute respiratory symptoms or a high-risk exposure history, as well as implementation of infection prevention and control precautions for all suspected and confirmed cases. Study outcomes include a positive SARS-CoV-2 test result and intensive respiratory support. RESULTS: In the period 1-30 April 2020, 702 of 3453 ED patients (20%; 95% CI 19-22) were tested, with a significant increase during the study period (incident rate ratio 1.019; 95% confidence interval 1.017-1.021, P < 0.001). The primary outcome of a positive SARS-CoV-2 test was recorded in 14 patients (2%; 95% confidence interval 1-3). Shortness of breath (77%), fatigue (100%), myalgia (67%) and diarrhoea (67%) were common among positive cases, while close contact (9%), fever (0%) and healthcare occupation (0%) were not. No positive cases required intensive respiratory support in the ED. CONCLUSIONS: The volume of ED patients with suspected COVID-19 is increasing. Low numbers of positive cases precluded development of accurate predictive tools, but the COVED Project is fulfilling an important role in monitoring the burden of infection prevention and control requirements on the ED. The increasing number of patients meeting isolation criteria has the potential to impact on patient flow and may lead to ED overcrowding.

Background Pediatric burn injury is one of the major causes of mortality and morbidity in the Kingdom of Saudi Arabia (KSA). Among survivors, long-term morbidity may have substantial impact. This study aimed to describe the epidemiology of pediatric patients admitted to the burns ICU at King Saud Medical City (KSMC) over a 10-year period. Methodology This was a retrospective cohort study and included all admitted patients to the burn ICU aged 0–14 years from January 2009 to December 2018. Explicit chart review of medical records was performed to extract demographics, Glasgow Coma Scale (GCS) on arrival, mechanism and extent of injury and in-hospital outcomes. Results There were 787 pediatric patients admitted in burn ICU over a period of 10 years. Of these, 56.4% were males and 54.7% were Saudi nationals. Most (73.8%) of injuries occurred at home, with 77% occurring were when the child was playing, and 81% were sustained from open flames. Most patients (757, 96%) admitted to the ICU were intubated with 499 (63.4%) diagnosed with inhalation injury. Patients spent an average of 12.6 (4.7) days in the burn ICU. There were 199 (25.3%) deaths at hospital discharge, and among patients discharged alive, 37.1% were discharged to inpatient rehabilitation. Conclusion There was substantial burden of severe burns in the KSA with majority secondary to flame injury and mostly occurring at home. Inhalation injury was common and indicates requirement for focused education on resuscitative strategies. Population-based education programs are indicated to reduce burn injuries and should be targeted to domestic settings in in the KSA.

Objective The COVID-19 Emergency Department (COVED) Quality Improvement Project aims to provide regular and real-time clinical information to ED clinicians caring for patients with suspected and confirmed COVID-19. The present study summarises data from the first 2 weeks of the study. Methods COVED is an ongoing prospective cohort study that commenced on 1 April 2020. It includes all adult patients presenting to a participating ED who undergo testing for SARS-CoV-2. Data are collected prospectively and entered into a bespoke registry. Outcomes include a positive SARS-CoV-2 polymerase chain reaction test result and requirement for intensive respiratory support. Results In the period 1-14 April 2020, 240 (16%) of 1508 patients presenting to The Alfred Emergency and Trauma Centre met inclusion criteria. Of these, 11 (5%) tested positive for SARS-CoV-2. The mean age of patients was 60 years and the commonest symptoms were acute shortness of breath (n = 122 [67%]), cough (n = 108 [56%]) or fever (n = 98 [51%]). Overseas travel or known contact with a confirmed case was reported by 24 (14%) and 16 (10%) patients, respectively. Fever or hypoxia was recorded in 23 (10%) and 11 (5%) patients, respectively. Eleven (5%) patients received mechanical ventilation in the ED, of whom none tested positive for SARS-CoV-2. Conclusions Among patients presenting to a tertiary ED with suspected COVID-19, only a small proportion tested positive for SARS-CoV-2. Although the low incidence of positive cases currently precludes the development of predictive tools, the COVED Project demonstrates that the rapid establishment of an agile clinical registry for emergency care is feasible.

Objectives: There is an urgency to support Australian ED clinicians with real‐time tools as the COVID‐19 pandemic evolves. The COVID‐19 Emergency Department (COVED) Quality Improvement Project has commenced and will provide flexible and responsive clinical tools to determine the predictors of key ED‐relevant clinical outcomes. Methods: The COVED Project includes all adult patients presenting to a participating ED and meeting contemporary testing criteria for COVID‐19. The dataset has been embedded in the electronic medical record and the COVED Registry has been developed. Results: Outcomes measured include being COVID‐19 positive and requiring intensive respiratory support. Regression methodology will be used to generate clinical prediction tools. Conclusion: This project will support EDs during this pandemic.

AIMS: To undertake a multicentre evaluation of translation of a partnered pharmacist medication charting (PPMC) model in patients admitted to general medical units in public hospitals in the state of Victoria, Australia. METHODS: Unblinded, prospective cohort study comparing patients before and after the intervention. Conducted in seven public hospitals in Victoria, Australia from 20 June 2016 to 30 June 2017. Patients admitted to general medical units were included in the study. Medication charting by pharmacists using a partnered pharmacist model was compared to traditional medication charting. The primary outcome variable was the length of inpatient hospital stay. Secondary outcome measures were medication errors detected within 24 h of the patients' admission, identified by an independent pharmacist assessor. RESULTS: A total of 8648 patients were included in the study. Patients who had PPMC had reduced median length of inpatient hospital stay from 4.7 (interquartile range 2.8–8.2) days to 4.2 (interquartile range 2.3–7.5) days (P < 0.001). PPMC was associated with a reduction in the proportion of patients with at least 1 medication error from 66% to 3.6% with a number needed to treat to prevent 1 error of 1.6 (95% confidence interval: 1.57–1.64). CONCLUSION: Expansion of the partnered pharmacist charting model across multiple organisations was effective and feasible and is recommended for adoption by health services.

BackgroundAlcohol and other drug (AOD) use is a key preventable risk factor for serious injuries. Prevention strategies to date have largely focused on transport injuries, despite AOD use being a significant risk factor for other injury causes, including falls. This systematic review aimed to report the prevalence of AOD use in patients presenting to hospital for fall-related injuries.MethodsThis systematic review includes studies published in English after the year 2010 that objectively measured the prevalence of AOD use in patients presenting to hospital for a fall-related injury. Screening, data extraction and risk of bias assessments were completed by two independent reviewers. Data were presented using narrative synthesis and, where appropriate, meta-analyses.ResultsA total of 12 707 records were screened. Full texts were retrieved for 2042 records, of which 29 were included. Four studies reported the combined prevalence of any alcohol and/or drug use, generating a pooled prevalence estimate of 37% (95% CI 25% to 49%). Twenty-two records reported on the prevalence of acute alcohol use alone and nine reported specifically on the prevalence of drugs other than alcohol, with prevalence ranging from 2% to 57% and 7% to 46%, respectively. The variation in prevalence estimates likely resulted from differences in toxicology testing methods across studies.ConclusionsAOD exposure was common in hospitalised fall-related injuries. However, research addressing prevalence across different types of falls and the use of drugs other than alcohol was limited. Future research should address these areas to improve our understanding of which populations should be targeted in AOD and injury prevention strategies .PROSPERO registration numberCRD42020188746.

The wide-spread use of an initial 'Glasgow Coma Scale (GCS) 8 or less' to define and dichotomise 'severe' from 'mild' or 'moderate' traumatic brain injury (TBI) is an out-dated research heuristic that has become an epidemiological convenience transfixing clinical care. Triaging based on GCS can delay the care of patients who have rapidly evolving injuries. Sole reliance on the initial GCS can therefore provide a false sense of security to caregivers and fail to provide timely care for patients presenting with GCS greater than 8. Nearly 50 years after the development of the GCS - and the resultant misplaced clinical and statistical definitions - TBI remains a heterogeneous entity, in which 'best practice' and 'prognoses' are poorly stratified by GCS alone. There is an urgent need for a paradigm shift towards more effective initial assessment of TBI.

Substance use is a risk factor for being both a perpetrator and a victim of violence. The aim of this systematic review was to report the prevalence of acute pre-injury substance use in patients with violence-related injuries. Systematic searches were used to identify observational studies that included patients aged ≥15 years presenting to hospital after violence-related injuries and used objective toxicology measures to report prevalence of acute pre-injury substance use. Studies were grouped based on injury cause (any violence-related, assault, firearm, and other penetrating injuries including stab and incised wounds) and substance type (any substance, alcohol only, drugs other than alcohol only), and they were summarized using narrative synthesis and meta-analyses. This review included 28 studies. Alcohol was detected in 13%–66% of any violence-related injuries (five studies), 4%–71% of assaults (13 studies), 21%–45% of firearm injuries (six studies; pooled estimate = 41%, 95% CI: 40%–42%, n = 9,190), and 9%–66% of other penetrating injuries (nine studies; pooled estimate = 60%, 95% CI: 56%–64%, n = 6,950). Drugs other than alcohol were detected in 37% of any violence-related injuries (one study), 39% of firearm injuries (one study), 7%–49% of assaults (five studies), and 5%–66% of penetrating injuries (three studies). The prevalence of any substance varied across injury categories: any violence-related injuries = 76%–77% (three studies), assaults = 40%–73% (six studies), firearms = n/a, other penetrating injuries = 26%–45% (four studies; pooled estimate = 30%, 95% CI: 24%–37%, n = 319).Overall, substance use was frequently detected in patients presenting to hospital for violence-related injuries. Quantification of substance use in violence-related injuries provides a benchmark for harm reduction and injury prevention strategies.

Australia is rapidly moving towards 'living with COVID-19', with relaxation of some public health measures. The number of severe cases of COVID-19 may be mitigated by vaccination, but 'living with COVID-19' will be associated with higher number of patients seeking emergency care. This impending impact on the emergency care system requires recognition, monitoring and co-ordinated management. Current challenges include a lack of emergency care monitoring systems, staff shortages and patient flow processes that are quickly overwhelmed by large numbers, particularly in a system already operating at capacity. Effective monitoring systems are required for health systems to proactively detect and respond to stresses. Additional solutions include public health messaging and clinical innovation to facilitate care of the right patient in the right place at the right time. Optimising staff numbers and morale, and efficient patient flow, are integral steps to increasing capacity within the emergency care system.

Objective The aim of the present study was to describe the characteristics and outcomes of patients presenting to Australian EDs with suspected and confirmed COVID‐19 during 2020, and to determine the predictors of in‐hospital death for SARS‐CoV‐2 positive patients. Methods This analysis from the COVED Project presents data from 12 sites across four Australian states for the period from 1 April to 30 November 2020. All adult patients who met local criteria for suspected COVID‐19 and underwent testing for SARS‐CoV‐2 in the ED were eligible for inclusion. Study outcomes were mechanical ventilation and in‐hospital mortality. Results Among 24 405 eligible ED presentations over the whole study period, 423 tested positive for SARS‐CoV‐2. During the ‘second wave’ from 1 July to 30 September 2020, 26 (6%) of 406 SARS‐CoV‐2 patients received invasive mechanical ventilation, compared to 175 (2%) of the 9024 SARS‐CoV‐2 negative patients (odds ratio [OR] 3.5; 95% confidence interval [CI] 2.3–5.2, P, The aim of COVED‐5 was to describe the characteristics and outcomes of patients presenting to Australian emergency departments (EDs) with suspected and confirmed COVID‐19 during 2020, and to determine the predictors of in‐hospital death for SARS‐CoV‐2 positive patients. ED patients who tested positive for SARS‐CoV‐2 had higher odds of mechanical ventilation and death in hospital. The strongest predictors of death were age, a higher triage category, obesity and receiving immunosuppressive treatment.

ObjectivesTo assess the association between soft-shell headgear (HG) use and sports-related concussion (SRC). Secondary objectives were to assess the association between HG and superficial head injury and investigate potential increase in injury risk among HG users.DesignA systematic search in Ovid MEDLINE, Cochrane Library, Scopus, PsycINFO and SPORTDiscus was conducted in April 2020. Inclusion criteria were youth Outcome measuresIncidence rates of SRC, superficial head injury or other injuries.ResultsEight studies were eligible. The majority (n=5) reported no difference in the rate of SRC among HG users versus non-users. One rugby study identified significantly lower risk of SRC for non-HG users (risk ratio (RR) 0.63; 95% CI 0.41 to 0.98) compared with HG users, whereas a cross-sectional survey of soccer players indicated higher risk of SRC for non-HG users (RR 2.65; 95% CI 1.23 to 3.12) compared with HG users. Three of the four studies investigating superficial head injury found no significant differences with HG use, though the soccer survey reported reduced risk among HG users (RR 1.86; 95% CI 0.09 to 0.11). Increased incidence of injuries to all body regions for rugby HG users was reported in two studies with adjusted RRs of 1.16 (95% CI 1.04 to 1.29) and 1.23 (95% CI 1.00 to 1.50).ConclusionsHG use was not associated with reduced rates of SRC or superficial head injury in youth soccer and rugby. The possibility of increased injury risk to all body regions for rugby HG users was raised. The need for research specific to youth and female athletes was highlighted.PROSPERO registration numberCRD42018115310.
