    ABSTRACT: Objective: We aim to investigate whether prehospital Modified Early Warning Score (MEWS) can identify non-trauma patients requiring life-saving intervention (LSI) within 4 h of presentation to the ED. Methods: It was a prospective study of non-trauma ED patients by ambulance who were 16 years or older from 1 to 27 November 2013. Prehospital MEWS was calculated according to vital signs measured by the ambulance crew. Data on patients' demographics, triage category, LSI within 4 h of ED presentation and 24 h mortality were retrieved. LSI was defined as emergency interventions to airway, breathing and circulation, emergency procedures and medications administered. The performance of prehospital MEWS was analysed with sensitivity, specificity, predictive values (PV), likelihood ratios (LR) and the receiver operating characteristic curve. Results: Recruited during the study period were 1493 patients. The median age was 78 years. Of the patients, 49.9% belonged to critical, emergent or urgent triage categories. LSI was required in 321 patients (21.5%). Thirteen died within 24 h of ED presentation. The area under the receiver operating characteristic curve of prehospital MEWS relating to LSI was 0.72 (95% confidence interval 0.69 to 0.75). The sensitivity, specificity, positive PV, negative PV, positive LR and negative LR were 0.57, 0.76, 0.40, 0.87, 2.43 and 0.56, respectively, when prehospital MEWS ≥3 was chosen as the cut-off value. Conclusions: Prehospital MEWS is useful in identifying non-trauma patients requiring LSI within 4 h of ED presentation. This may in turn enhance the triage accuracy in the ED in addition to clinical assessment.

    ABSTRACT: Objectives: One out of 50 injury-related presentations to an ED is a transport-related cycling injury. Detailed information about the most frequent mechanism of cycling injuries, sustained injuries and patterns are under-reported. The objective of this research was to examine the pattern of injuries sustained by cyclists at a level 1 trauma centre. Methods: A retrospective review of data of injured cyclists admitted and treated at a level 1 trauma centre between 2011 and 2012 evaluated demographic data, mechanism of injury, injury pattern, economic costs and outcome. Results: Data of 261 patients (mean age of 39 years) were reviewed, of which 88% was male patients with an average age of 38 years. Non-collision cycling injuries were reported in 55% of cases followed by collisions with other motor vehicles in 25.6% of cases. The mean injury severity score (ISS) was 9, but an ISS ≥ 12 was documented in 24%. Predominantly upper limb injuries (24.8%) were found, followed by injuries to the head and lower limb (each with 16.8%). Traumatic brain and chest injuries were equally seen in 8%. The overall length of stay was 4 days, and survival rate was 98%. Conclusion: This current data review reveals that non-collision traffic crashes accounted for the majority of injuries in cyclists treated in this facility, and the upper limb has replaced the head as the most injured body part. With a growing number of cyclists, this information contributes to considerations to improve road safety and trauma management.

    ABSTRACT: In recent years, the Australasian College for Emergency Medicine (ACEM) has increasingly focused on the need for high-quality research in emergency medicine (EM). One important initiative was the establishment of the ACEM Foundation, which among other responsibilities, is required to support clinical research through the provision of research funding and other measures. In February 2015, the Foundation held a Research Forum that was attended by the leading EM researchers from Australasia. The Forum aimed to determine how a productive research culture could be developed within the ACEM. Nine key objectives were determined including that research should be a core business of the ACEM and a core activity of the EM workforce, and that EM research should be sustainable and adequately supported. This report describes the background and conduct of the Forum, its recommendations and the way in which they could be implemented.

    ABSTRACT: Objectives: Despite efforts to restructure mental health (MH) services across Victoria, the social and economic burden of MH illness continues to grow. This study compares MH presentations to EDs with a study undertaken 10 years earlier. Methods: The article is a retrospective observational study of MH presentations to four Victorian EDs between May and October 2013. Subjects were included if the presentation was MH related as determined by an International Classification of Diseases (version 10) discharge diagnosis, they were referred to an emergency crisis assessment team or had a documented presenting psychiatric complaint. Variables were extracted from electronic medical records and compared with 2004 data from a previous published study. Results: There were 5659 MH presentations over the 5 months compared with 2788 in 2004. The median ED length of stay decreased from 4:18 h in 2004 to 3:20 h in 2013 (P < 0.001), with a significant reduction in length of stay >4 h from 52.5% to 35.4% (P < 0.001). There was a 22-fold increase in short stay units as discharge destination from 0.9% to 20.2% (P < 0.001). Patients presenting with concurrent methamphetamine exposure doubled from 2.2% of presentations to 4.3% (P < 0.001). Conclusion: Despite increasing MH-related presentations, changes in ED practice have allowed improvements in delivery of care through a shortened ED length of stay and the virtual elimination of very long stays over 24 h. However, there continues to be significant variability in management and performance across hospital sites. Identifying which interventions lead to standout site performance, and subsequent application more broadly, may improve future ED delivery of care.

    ABSTRACT: Objectives: We aimed to provide 'adequate analgesia' (which decreases the pain score by ≥2 and by <4 [0-10 scale]) and determine the effect on patient satisfaction. Methods: We undertook a multicentre, cluster-randomised, controlled, intervention trial in nine EDs. Patients with moderate pain (pain score of ≥4) were eligible for inclusion. The intervention was a range of educational activities to encourage staff to provide 'adequate analgesia'. It was introduced into five early intervention EDs between the 0 and 6 months time points and at four late intervention EDs between 3 and 6 months. At 0, 3 and 6 months, data were collected on demographics, pain scores, analgesia provided and pain management satisfaction 48 h post-discharge (6 point scale). Results: Overall, 1317 patients were enrolled. Logistic regression (controlling for site and other confounders) indicated that, between 0 and 3 months, satisfaction increased significantly at the early intervention EDs (OR 2.2, 95% CI 1.5 to 3.4 [P < 0.01]) but was stable at the control EDs (OR 0.8, 95% CI 0.5 to 1.3 [P = 0.35]). Pooling of data from all sites indicated that the proportion of patients very satisfied with their pain management increased from 42.9% immediately pre-intervention to 53.9% after 3 months of intervention (difference in proportions 11.0%, 95% CI 4.2 to 17.8 [P = 0.001]). Logistic regression of all data indicated that 'adequate analgesia' was significantly associated with patient satisfaction (OR 1.4, 95% CI 1.1 to 1.8 [P < 0.01]). Conclusions: The 'adequate analgesia' intervention significantly improved patient satisfaction. It provides a simple and efficient target in the pursuit of best-practice ED pain management.

    ABSTRACT: Objective: We aim to investigate whether a bundle of changes made to the practice of endotracheal intubation in our ED was associated with an improvement in first pass success rate and a reduction in the incidence of complications. Methods: We used a prospective observational study. Results: The data on 360 patients who were intubated during an 18-month period following the introduction of these changes were compared with our previously published observational data. Success on first attempt at intubation improved 83.4% to 93.9% (P < 0.0001). The proportion of patients with one or more complication fell from 29.0% to 19.4% (P < 0.042). Oesophageal intubation fell from 4.0% to 0.3% (P < 0.001), and there was a non-significant reduction in the rate of desaturation, from 15.6% to 10.9% (P < 0.07). Conclusion: We have shown that, through the introduction of a bundle of changes that spans the domains of staff training, equipment and practice standardisation, we have made significant improvements in the safety of patients undergoing endotracheal intubation in our ED.

    ABSTRACT: Objective: This study aimed to determine the reliability of the Abbreviated Westmead Post-traumatic Amnesia Scale (A-WPTAS) in children by examining the impact of age on A-WPTAS performance. Methods: Participants were typically developing patients with minor illnesses or injuries and/or accompanying siblings aged 5-10 years, attending a children's hospital ED. Exclusion criteria included: (i) a recent traumatic brain injury; (ii) developmental disability; (iii) recent drug administration judged to impact cognition; and/or (iv) non-English speaking background. The A-WPTAS was administered on two occasions separated by approximately 60 min. Logistic regression was used to determine the odds of passing based on age. Results: A total of 125 children completed the A-WPTAS assessments. A-WPTAS pass rates were 36% for 5 year olds, 68% for 6 year olds, and exceeded 90% for 7-10 year olds. Compared with 9 year olds, 5 year olds had significantly lower odds of passing (P = 0.003), a trend that persisted for 6 year olds (P = 0.052). Among 5 and 6 year olds, failure was predominantly due to difficulty with temporo-spatial orientation items. Conclusions: The A-WPTAS is reliable for use in children aged 7 years and older, while its use in children aged 6 years and under results in an unsatisfactory high false positive rate, limiting its clinical utility. The adult-level performance of children aged 7 years onwards provides strong support for using the tool in the early management of these children with mild traumatic brain injury in Australian EDs.

    ABSTRACT: Only recently has the potential (unmet) palliative care (PC) workload in the ED been recognised. While confident in PC symptom management, we underestimate the role of a palliative approach in non-cancer diagnoses and seek education in areas such as individual patient care pathways, ethical and legal issues and difficult conversations at the end of life. PC is best introduced early for a range of life-limiting cancer and non-cancer diagnoses. Allowing patients time to tell their story with active listening, acknowledgement of suffering and a compassionate presence leads to treatment 'success' that is not defined by cure. This patient-centred, rather than disease-centred approach, is the essence of PC, and one that is easily incorporated into emergency practice. PC and disease-specific treatments can comfortably coexist, and with meticulous symptom management, may actually prolong life. PC is everyone's business, and emergency medicine needs to be part of it.

    ABSTRACT: Objective: Despite recent efforts, most people are not trained in cardiopulmonary resuscitation (CPR), which has a major impact on survival following cardiac arrest (CA). We have set up a dispatcher-assisted CPR protocol at our call centre, based on international guidelines issued in 2010. The aim of our study was to evaluate the impact of this protocol on CA diagnosis and quantity of recommendations given by telephone dispatchers to untrained witnesses. Methods: We performed a 'before and after' monocentric observational study. Data were compared before and a short time after (2 months) implementation of the protocol. We included patients presenting as an out-of-hospital CA in the presence of a witness untrained in CPR. Fisher's test was used to compare periods. P < 0.05 was considered significant. Results: During the 8 month period before the protocol, 115 victims were potentially eligible for CPR. Diagnosis was achieved in 63.5% of cases and CPR recommendations given in 6.1%. After implementation of the protocol, 130 victims were potentially eligible for CPR. Frequency of CA diagnosis was significantly higher after the protocol with 76% of cases (P = 0.0359). Frequency of CPR recommendations given to witnesses was also significantly higher after the protocol, with a fivefold increase up to 29.2% (P < 0.0001). Conclusion: Implementation of a dispatcher-assisted CPR protocol was efficient in improving both CA diagnosis and CPR recommendations given to untrained witnesses for out-of-hospital CA with a very short time of dispatcher training. It is a simple and efficacious measure, at no additional cost and with the promises of improving prognosis following cardiac arrest in a centre not equipped with computerised dispatcher support programmes.

    ABSTRACT: Objective: We evaluated the decrease in chest compression depth during continuous one-handed chest compression (OHCC) in an in-hospital paediatric arrest setting, and whether switching hands could delay the decrease in chest compression depth. Methods: In total, 30 healthcare providers were randomised into groups A and B. Group A performed test 1 (chest compressors alternated hands every 30 s in 2 min of OHCC), followed by test 2 (chest compressors used one hand for 2 min without switching to the other hand) and group B, vice versa. Participants performed 2 min continuous OHCC on a paediatric manikin on a bed. Mean compression depth (MCD) and mean compression rate (MCR) were analysed at 30 s intervals. Results: The MCDs in 30 s intervals changed significantly with time passed in tests 1 and 2 (0-30 s: 43.4 ± 7.4 vs 42.8 ± 7.6 mm, 30-60 s: 42.8 ± 8.7 vs 40.3 ± 8.8 mm, 60-90 s: 40.5 ± 8.9 vs 38.2 ± 9.6 mm, 90-120 s: 40.2 ± 10.2 vs 36.9 ± 9.7 mm; P < 0.01). However, with the exception of the first 30 s interval, MCD in test 1 showed significantly higher values than in test 2 (P < 0.05). The MCRs in 30 s intervals did not change significantly with time passed in all tests and were not different between the two tests. All hand-off times measured during switching hands in test 1 were less than 1 s. Conclusions: Chest compression depth decreased significantly when continuous OHCC was performed without switching hands. Alternating hands every 30 s can delay the decrease in MCD and maintain deeper MCD for longer.
