    ABSTRACT: Objectives The objectives of the present study were to describe the injury profiles of cyclists presenting to an ED and determine the risk of significant head injury associated with bicycle helmet use.Methods This was a retrospective single trauma centre study of all adult cyclists presenting to an inner city ED and undergoing a trauma team review between January 2012 and June 2014. The outcome of interest was significant head injury defined as any head injury with an Abbreviated Injury Scale score of two or more. Variables analysed included demographic characteristics, helmet use at time of incident, location, time and the presence of intoxication.ResultsThe most common body regions were upper limb injuries (57%), followed by head injuries (43%), facial injuries (30%) and lower limb injuries (24%). A lower proportion of people wearing helmets had significant head injury (17% vs 31%, P = 0.018) or facial injury (26% vs 48%, P = 0.0017) compared with non-helmet users. After adjustment for important covariates, helmet use was associated with a 70% decrease in the odds of significant head injury (odds ratio 0.34, 95% confidence interval 0.15, 0.76, P = 0.008).Conclusions Head injuries were common after inner city cycling incidents. The use of helmets was associated with a reduction in significant head injury.

    ABSTRACT: The fly-on-the-wall medical documentary is a popular television phenomenon. When patients can give appropriate consent to filming, the final product can be both educational for the public and rewarding for its subjects. However, in the dynamic world of emergency and prehospital medicine, consenting critically ill patients before filming is a significant challenge. The main barriers to gaining valid consent in the field and in the ED are limited time to inform the patient and the diminished capacity of the sick patient. Although there is an argument that involvement in a commercial film might be beneficial to several parties, including the patient, these benefits do not amount to therapeutic necessity if prior consent is not obtainable. Despite this, we still see acutely incapacitated patients featured in some television programmes. In these cases, the conventional process of consent might be being sidestepped in order to obtain permission for broadcast retrospectively. This alternative process fails to recognise that incapacitated patients require protection from an invasion of privacy that occurs when a crew is filming their resuscitations. This harm has already occurred by the time consent is sought. Ultimate responsibility for defending the patients' interests during their medical treatment rests with the medical practitioner. We argue that filming a patient without prior consent in both the prehospital and emergency environment is ethically unsound: it threatens trust in the healthcare relationship and might compromise the patient's dignity and privacy. Robust guidelines should be developed for all healthcare professionals who engage with commercial film crews. © 2015 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    ABSTRACT: Standard ampoules and prefilled syringes of adrenaline are widely available in Australasian EDs for use in cardiac arrest. We hypothesise that prefilled syringes can be administered more rapidly and accurately when compared with the two available standard ampoules. This is a triple arm superiority study comparing the time to i.v. administration and accuracy of dosing of three currently available preparations of adrenaline. In their standard packaging, prefilled syringes were on average more than 12 s faster to administer than the 1 mL 1:1000 ampoules and more than 16 s faster than the 10 mL 1:10 000 ampoules (P < 0.01 in both comparisons). With packaging removed, the time to administration was equal for the 1 mL (1:1000) ampoule and the prefilled syringe. Accuracy of dosing was excellent with both the 10 mL (1:10 000) ampoules and prefilled syringes. The 1 mL (1:1000) ampoules delivered a small number of markedly inaccurate doses, but these did not reach statistical significance. The speed of administration of adrenaline utilising a Minijet (CSL Limited, Parkville, Victoria, Australia) is faster than using adrenaline in glass ampoules presented in their plastic packaging. Removing the plastic packaging from the 1 mL (1 mg) ampoule might result in more rapid administration similar to the Minijet. Resuscitation personnel requiring rapid access to adrenaline should consider storing it as either Minijets or ampoules devoid of packaging. These results might be extrapolatable to other clinical scenarios, including pre-hospital and anaesthesia, where other drugs are required for rapid use. © 2015 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    ABSTRACT: Shortness of breath is a common reason for ED attendance. This international study aims to describe the epidemiology of dyspnoea presenting to EDs in the South East Asia-Pacific region, to compare disease patterns across regions, to understand how conditions are investigated and treated, and to assess quality of care. This is a prospective, interrupted time series cohort study conducted in EDs in Australia, New Zealand, Singapore, Hong Kong and Malaysia of consecutive adult patients presenting to the ED with dyspnoea as a main symptom. Data were collected over three 72 h periods in May, August and October 2014 (autumn, winter and spring), and included demographics, comorbidities, mode of arrival, usual medications, pre-hospital treatment, initial assessment, ED investigations, treatment in the ED, ED diagnosis, disposition from ED, in-hospital outcome and final hospital diagnosis. The primary outcomes of interest are the epidemiology and outcome of patients presenting to ED with dyspnoea. Secondary outcomes of interest are seasonal and geographic comparisons of diagnoses and outcomes, disease-specific descriptions of epidemiology, investigation, treatment and disposition, and compliance with treatment guidelines. This novel study will explore dyspnoea from the viewpoint of the patient's symptom (shortness of breath) rather than that of a single disease. The results will provide robust data about the epidemiology, investigation, treatment and disposition of this diverse patient group. The obtained data also have the potential to inform service planning and to quantify the proportion of patients with mixed cardiac and respiratory disease. © 2015 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    ABSTRACT: To determine the magnitude and characteristics of the increase in ED demand in Western Australia (WA) from 2007 to 2013. We conducted a population-based longitudinal study examining trends in ED demand, stratified by area of residence, age group, sex, Australasian Triage Scale category and discharge disposition. The outcome measures were annual number and rate of ED presentations. We calculated average annual growth, and age-specific and age-standardised rates. We assessed the statistical significance of trends, overall and within each category, using the Mann-Kendall trend test and analysis of variance ANOVA. We also calculated the proportions of growth in ED demand that were attributable to changes in population and utilisation rate. From 2007 to 2013, ED presentations increased by an average 4.6% annually from 739 742 to 945 244. The rate increased 1.4% from 354.1 to 382.6 per 1000 WA population (P = 0.02 for the trend). The main increase occurred in metropolitan WA, age 45+ years, triage category 2 and 3 and admitted cohorts. Approximately three-quarters of this increase was due to population change (growth and ageing) and one-quarter due to increase in utilisation. Our study reveals a 4.6% annual increase in ED demand in WA in 2007-2013, mostly because of an increase in people with urgent and complex care needs, and not a shift (demand transfer) from primary care. This indicates that a system-wide integrated approach is required for demand management. © 2015 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    ABSTRACT: It is unclear whether emerging evidence for harm from aggressive fluid resuscitation for paediatric sepsis has altered clinical practice. We surveyed senior emergency physicians to see if their fluid resuscitation practices conformed to published clinical guidelines. This is a cross-sectional, Internet-based survey of senior emergency medical staff in any of 12 Paediatric Research in Emergency Departments International Collaborative (PREDICT) Network centres in Australia and New Zealand. There were 110 of 120 (92%) senior medical staff who responded. Ninety-eight per cent of respondents used 0.9% saline as their primary resuscitation fluid. Sixty-two per cent of respondents used 20 mL/kg fluid bolus for every bolus, 30% used 20 mL/kg for the first bolus and 10 mL/kg subsequently. Response to fluid bolus administration was based on clinical parameters in 92% of respondents (heart rate, BP, skin perfusion/mottling and central capillary refill), conscious state in 80% and venous lactate in 75%. Harm from fluid bolus administration was routinely monitored for by 81% of respondents. In those assessing for harm, clinical parameters were reported to be most commonly used (respiratory rate and effort in 60%, SpO2 in 55%, presence of crackles on lung auscultation in 50% and hepatomegaly in 42%). Invasive or ultrasound-based monitoring was used infrequently. Paediatric sepsis is reported to be managed by senior emergency physicians largely according to published guidelines. At this time, evidence for potential harm from fluid bolus resuscitation has not altered practice. © 2015 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.
