Objective: Orbital compartment syndrome (OCS) is a time critical condition, with ischaemic complications occurring after 90–120 min. In the prehospital setting, the diagnosis and management of OCS is challenging due to complex environmental considerations, competing clinical priorities, and limited equipment. This study aims to provide learning points on performing lateral canthotomy and cantholysis (LCC) in the prehospital setting. Methods: We performed a retrospective audit of LCC in our service from January 2016 to December 2020 by retrieving demographic and clinical details from LifeFlight Retrieval Medicine electronic database using 'OCS' and 'LCC' as keywords. Results: Three cases out of 7413 trauma missions were identified over the 5‐year period. LCC was performed at the primary scene in two cases, while one patient underwent LCC at a rural hospital near the scene of injury. Clinical findings, aeromedical considerations, and radiological findings at the receiving facility, along with visual outcomes at time of discharge are discussed. Conclusion: Prehospital LCC is rare. The Australian aeromedical context often involves lengthy transfers of trauma patients. Clinical diagnosis and management of OCS are highly challenging in the prehospital setting. It is important that prehospital physicians have access to appropriate equipment to perform LCC. They should be provided with suitable training and supported by a standard operating procedure.

Objective: To investigate differences in presenting patient characteristics, investigation, management and related outcomes between culturally and linguistically diverse (CALD) and non‐CALD chest pain (CP) patients presenting to the ED. Methods: A cohort study of 258 patients was enrolled on presentation to Liverpool Hospital ED with a complaint of CP over a 2‐week period. Main outcomes included frequency and timeliness of diagnostic and radiological investigations, medication administered and ED length of stay. Administrative and clinical data were extracted and linked from Cerner EMR FirstNet®, PowerChart® and paper records. Results: There were 155 (60%) CALD and 103 (40%) non‐CALD patients. CALD patients were older by 10 years (95% CI 4, 15; P < 0.0001). There were no significant differences in the number of pathology and imaging investigations carried out in each group, and similarly there were no significant differences in the number of patients administered analgesia or cardiac‐specific medications. Neither group differed in their ED length of stay (median 280 vs 259.5 min; P = 0.79) or hospital admission rate (median 56% vs 55%, P = 0.8). Conclusion: Both CALD and non‐CALD ED CP patients had similar test ordering, medication administration and clinical outcomes, but this was in the context of CALD patients being 10 years older together with a small study sample size. A larger cohort, matched for age, would provide further insights into potentially important differences. [ABSTRACT FROM AUTHOR]

Background: Sharing anonymised ED data with community agencies to reduce alcohol‐related injury and assaults has been found effective in the UK. This protocol document outlines the design of an Australian multi‐site trial using shared, anonymised ED data to reduce alcohol‐related harm. Design and Method: Nine hospitals will participate in a 36 month stepped‐wedge cluster randomised trial. After a 9 month baseline period, EDs will be randomised in five groups, clustered on geographic proximity, to commence the intervention at 3 monthly intervals. 'Last‐drinks' data regarding alcohol use in the preceding 12 h, typical alcohol consumption amount, and location of alcohol purchase and consumption, are to be prospectively collected by ED triage nurses and clinicians at all nine EDs as a part of standard clinical process. Brief information flyers will be delivered to all ED patients who self‐report risky alcohol consumption. Public Health Interventions to be conducted are: (i) information sharing with venues (via letter), and (ii) with police and other community agencies, and (iii) the option for public release of 'Top 5' venue lists. Outcomes Primary outcomes will be: (i) the number and proportion of ED attendances among patients reporting recent alcohol use; and (ii) the number and proportion of ED attendances during high‐alcohol hours (Friday and Saturday nights, 20.00–06.00 hours) assigned an injury diagnosis. Process measures will assess logistical and feasibility concerns, and clinical impacts of implementing this systems‐change model in an Australian context. An economic cost–benefit analysis will evaluate the economic impact, or return on investment. [ABSTRACT FROM AUTHOR]

Objective: The aim of the study is to describe the epidemiology of major bleeding fatalities. Methods: A case series analysis of Australia's National Coronial Information System was conducted. Keywords were used to search for closed cases of major haemorrhage in the state of Victoria for the period 1 January 2009 to 31 December 2011. Coroners' findings, autopsy reports and police reports of cases were reviewed. Demographic data were extracted, and cases were assigned to a clinical bleeding context. Results: A total of 427 cases of major bleeding causing death were identified. The cohort was predominately men (69%), with a median age of 63 years (interquartile range 45-77 years). Trauma accounted for 38%, gastrointestinal haemorrhage 28%, surgical/procedural bleeding 14%, ruptured/leaking aneurysms 12% and other 8%. Most events began in homes (46%), hospitals (22%) and at the roadside (17%). Of those whose haemorrhage began in the community, 69% did not survive to hospital. Conclusions: Major bleeding fatalities occurred across a diverse range of contexts, with trauma and gastrointestinal bleeding accounting for most deaths. The majority of patients did not survive to reach hospital. Major haemorrhage occurring entirely outside hospital may be underrecognised from analyses of datasets based primarily on traumatic or in-hospital bleeding. These findings have implications for management of pre-hospital resuscitation and development of clinical practice guidelines for identification and management of major bleeding in the community.

Objective Anticoagulant and antiplatelet ( ACAP) drugs are associated with increased mortality in trauma patients, therefore medication history on admission is important. Whether these medications are recorded on trauma admission has not been investigated, nor if absence of a medication history is associated with worse patient outcomes. Methods We conducted a retrospective database review combining demographic and outcome data from the St George Hospital (Sydney) trauma registry with admission medication history in the electronic record. To contrast medications with a known increased risk ( ACAP) to patients with unknown risk, patients were divided into three groups: those on ACAPs, no- ACAP if medication history was present and no- ACAP documented, or no-Hx if no medication history recorded. Inclusion criteria were aged >16 and Injury Severity Score ( ISS) >12. Admission demographic data and outcome data were compared between all three groups. Results Of 533 consecutive patients, 21% comprised the no-Hx group, while 22% were on an ACAP and 57% not on an ACAP. No-Hx patients had more severe head injuries and a younger median age compared to ACAP patients (42 vs 82 years old, P < 0.001). Mortality was higher for ACAP (24%; 95% CI 17-33%) compared to no- ACAP (11%; 95% CI 8-16%) or no-Hx patients (12%; 95% CI 7-20%) ( P = 0.04). Conclusions While a large number of severe trauma patients were admitted without a medication history, no-Hx patients did not appear at increased risk of adverse outcomes. ACAP patients had a higher mortality compared to no- ACAP highlighting the vulnerability of this group. [ABSTRACT FROM AUTHOR]

Objective Age-related policies allow adolescents to access paediatric and adult EDs. Anecdotally, paediatric and adult EDs report challenges when caring for older and younger adolescents, respectively. Our aim was to describe the characteristics of an adolescent population attending an adult ED, co-located with a tertiary paediatric ED. Methods The Westmead Hospital ED database was accessed for 14.5-17.9 years old presentations between January 2010 and December 2012. Patient diagnosis coding ( SNOMED) was converted to ICD-10. De-identified data were transferred into Microsoft Excel with analysis performed using spss V22. Results There were 5718 presentations made to the Westmead Hospital, Sydney, Australia ED by 4450 patients, representing 3.3% (95% CI 3.2-3.4) of total visits from all patients 14.5 years and above. The mean age of the sample was 16.6 years (male 51.8%). Presentations triaged as level 4 or 5 represented 61.0% (95% CI 58.7-61.3) of visits. The proportion of patients who did not wait to receive care was 13.8% (95% CI 12.9-14.7), which was significantly higher than adult rates ( P < 0.01). There were 279 unscheduled return visits (visits made <72 h of discharge) representing 4.9% (95% CI 4.4-5.8) of all presentations. Injury was the most common diagnosis (30.2%, 95% CI 28.8-31.6). Chronic physical illness and alcohol-related visits comprised 2.1% (95% CI 1.7-2.5) and 0.8% (95% CI 0.6-1.0) of adolescent presentations, respectively. Conclusion Contrary to reported staff perceptions, adolescent chronic physical illness presentations were not a major burden. Alcohol was likely under-recorded as a contributing factor to presentations. [ABSTRACT FROM AUTHOR]

Signs of Irukandji syndrome (IS) suggest an underlying catecholamine storm with research demonstrating that Carukia barnesi venom causes a significant rise in adrenaline/noradrenaline serum levels. A systematic review was undertaken to ascertain the current evidence in treating IS with magnesium salts. A literature search was conducted using Scopus, Medline and ScienceDirect. Further articles were discarded via title description and/or abstract details. The remaining were read in full, and those identified as not having sufficient information regarding magnesium and patient outcomes were removed. Nine articles were identified. One article was a randomised controlled trial, which concluded that there appears to be no beneficial difference between those patients who received the magnesium sulphate (MgSO4) and those who received the placebo and recommended against the use of MgSO4 in IS. Of the remaining eight, one reported the failure of MgSO4 and the remaining seven were case series reporting varying success in its use. This systematic review found insufficient evidence to support any clear recommendation regarding the use of magnesium, but nor was there clear evidence to recommend against its use in IS. Two case series describe significant reduction in key symptoms and hypertension but are a non-randomised albeit prospective series with the limitations accompanying this. The reporting of recrudescence of symptoms with reduction of dose does suggest a dose-response relationship. The evidence for the use of MgSO4 is at best anecdotal, and further research is required to either confirm its benefit or confirm the randomised controlled trial. [ABSTRACT FROM AUTHOR]

Objective Incident reporting systems are critical to understanding adverse events, in order to create preventative and corrective strategies. There are very few systems dedicated to Emergency Medicine with published results. All EDs in Australia and New Zealand were contacted to encourage the use of an Emergency Medicine - specific online reporting system called the Emergency Medicine Events Register (EMER). Methods We conducted an analysis of the first 150 incidents entered into EMER. EMER captures Emergency-medicine-specific details including triage score, clinical presentation, outcome, contributing factors, mitigating factors, other specialities involved and patient journey stage. These details were analysed by an expert panel. Results Over the first 26 months, 150 incidents were reported into EMER. The most common categories reported, in order, were diagnostic error, procedural complication and investigation errors. Most incidents contained more than one category of error. The most common stage of the patient's journey in which an incident was detected was after discharge from the ED. Conclusion A focus on correct diagnosis, procedure performance and investigation interpretation may reduce errors in the ED. The ability to learn from incidents and make system changes to enhance patient safety in healthcare organisations is an inherent part of providing a proactive, quality culture.

Objective To interrogate the National Coroners Information System ( NCIS) to determine the recurrent themes among coroners' recommendations that aimed to increase the safety of ED care. Methods This was a retrospective analysis of NCIS closed cases, from Queensland, New South Wales, Tasmania, Victoria, Australian Capital Territory, South Australia and North Territory, entered since its inception in 2000. The keyword 'emergency department' returned 1645 cases, of which 180 were found to be relevant. The primary outcomes were the number and nature of cases where recommendations for improvements in ED care had been made and the recurrent themes of these recommendations that could inform education initiatives. Results Of the 180 cases, 108 (60.0%) were of deceased men and subject age ranged from 2 days to 91 years. The commonest causes of death were trauma (26.7%), infection (24.4%), cardiac events (15.0%) and poisoning (8.9%). No coronial recommendations were required in 19 cases. For the remainder, recommendation themes related to issues of risk management/medico-legal, diagnostic/therapeutic error, education, documentation/communication and re-presentation. The themes associated with the different doctor designations (consultant, registrar, resident/intern) were similar, although registrars and residents/interns tended towards more diagnostic/therapeutic errors. The themes associated with hospital type (referral, urban, regional/rural) were also similar. Although theme analysis is important, some individual cases were particularly instructive. Conclusion The NCIS data theme analysis indentifies important high-risk patients and presenting complaints. These should be incorporated into emergency physician training. EDs should review the coronial recommendations to ensure that, where possible, they have been adopted. [ABSTRACT FROM AUTHOR]

Research is an important part of emergency medicine and provides the scientific underpinning for optimal patient care. Although increasing numbers of emergency physicians participate in research activities, formal research training is currently neither part of emergency physician training in Australia nor easily available for clinicians interested in clinical research. In a two-part series, which is targeted at part-time clinical researchers in the ED, we set out and explain the key elements for conducting high-quality and ethical research. Part I addressed ethical and regulatory aspects. In Part II, we describe important elements of research science, and practical elements of research conduct and administration, which form the basis for high-quality research. [ABSTRACT FROM AUTHOR]
