    ABSTRACT: Objective Prognostic models are commonly used in the clinical setting. The objective of the study is to evaluate the prognostic accuracy of the Rapid Emergency Medical Score (REMS) or alternate models.MethodsA retrospective cohort study of critical care patients who underwent retrieval service transfer to an ICU in a single state-wide service in Victoria, Australia. All patients aged 18 years and over transferred to an ICU between 1 January 2010 and 30 June 2013. Retrieval and ICU datasets were probabilistically linked. Multivariable logistic regression modelling was used to investigate the capacity of physiological markers and patient characteristics to predict in-hospital mortality in the ICU population. The prediction performance was evaluated using measures of discrimination (C-statistic) and calibration (Hosmer–Lemeshow [H-L statistic] ).ResultsThere were 1776 ICU patients who were transferred and 1749 (98.5%) had complete data. Of the 1749 patients with complete data, 257 (14.7%) died in-hospital. The REMS calculated at the time of retrieval referral demonstrated borderline predictive capability (C-statistic 0.69, 95% CI 0.62–0.76). Following logistic regression analysis of the REMS components, final variables included in the Retrieval REMS model were age, mean arterial pressure and Glasgow Coma Scale score. This model demonstrated acceptable predictive capability (C-statistic 0.72, 95% CI 0.64–0.79). The median (interquartile range [IQR]) Retrieval REMS for survivors and non-survivors, respectively, were 7 (5, 10) and 9 (7, 11), P < 0.01.Conclusions The availability of a validated tool such as Retrieval REMS assists recognition of high-risk patients and consideration of this risk in retrieval mission planning and response.

    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.

    ABSTRACT: Objective: To document the number of adolescents aged 16 years and under presenting to the ED at Joondalup Health Campus (JHC) with problems related primarily to alcohol intoxication, and document information about these presentations. Method: Presentations of adolescents were sourced from the Emergency Department Information System database at JHC. The patient's notes were interrogated for data on presentation and discharge times, means of arrival to the ED, age, gender, arrival Glasgow Coma Score (GCS), location from where the adolescent was brought and blood alcohol levels (BALs), if done. These were analysed, and descriptive statistics was reported. Results: Fifty-six adolescents (61% girls) were brought in to JHC ED with alcohol intoxication in 2013. The majority (76.8%) arrived between 21.00 hours and 05.00 hours, most often by ambulance or police (58.9%). Most adolescents had BALs performed (80.4%) and of those, nearly seven in eight (86.7%) had a BAL >0.1 g/L, with a mean of 0.161 g/L (SD 0.066). Girls had a lower mean BAL, but 26.5% presented with a GCS <14. Most 16 year olds were brought from organised parties, whereas other age groups were more likely drinking at a friend's house or with friends. Few (12.5%) were drinking at home. Conclusion: Adolescents requiring review in an ED for alcohol intoxication are most often brought in by ambulance or police in the late evening or early morning. They are most likely to have high BALs and a significant proportion will have a GCS <14.

    ABSTRACT: Objectives: The aim of the study was to determine if oxygen delivered through humidified high flow nasal cannulae (HHFNC) reduced the need for escalation in ventilation management and work of breathing in the ED patients presenting with acute undifferentiated shortness of breath compared with standard oxygen therapy. Methods: This was an unblinded randomised control trial conducted at two hospital EDs in Sydney, Australia. Eligible patients presenting with shortness of breath were randomised to HHFNC or standard oxygen therapy. Primary outcomes were the need to escalate ventilation therapy or a reduction in respiratory rate of 20% or more within 2 h of commencement. Results: One hundred patients were enrolled in the trial. The intervention group receiving HHFNC was associated with a higher proportion of patients with a reduced respiratory rate at 2 h (66.7% vs 38.5%, P = 0.005) and a lower proportion of patients requiring escalation in ventilation therapy (4.2% vs 19%, P = 0.02) compared with standard oxygen therapy. Conclusions: The use of high flow nasal cannula oxygenation was associated with improved respiratory state in selected patients presenting to the ED with acute undifferentiated shortness of breath.

    ABSTRACT: Objective: Femoral nerve blocks (FNBs) are commonly administered to patients with a fractured neck of femur (NOF). FNBs reduce complications associated with opioids and are effective for up to 24 h. However, the recognised 'gold standard' time to definitive treatment (surgery) in the patient with a fractured NOF is within 48 h. This leaves a significant period of time in which the patient has no effective analgesia, and might require opioids to alleviate pain. The present study explored the number of NOF patients who received a FNB: their wait for definitive treatment (surgery) and how much opioid analgesia was administered in the preoperative phase. Methods: A retrospective review of electronic patient records was conducted over a 6 month period in 2012. Patients who presented to the ED with a fractured NOF, received a FNB and were transferred to surgery in the same hospital were included in the sample. Results: The median time from FNBs to surgery was 37.5 h. When patients waited more than 20 h for surgery, the volume of opioid received increased significantly (P ≤ 0.001). Conclusion: Even when patients' time to surgery was within the 'gold standard', patients received increasing doses of opioids 20 h after the administration of the FNB. While patients continue to wait extended periods for surgery, the practice of administering a single injection FNB needs to be challenged. ED clinicians might consider FNB infusions rather than single injection FNBs for patients with a fractured NOF.

    ABSTRACT: Objective: To understand the attitudes of consultant emergency medicine physicians and advanced trainees and the perceived barriers to public health interventions in Australasian EDs. Methods: This was a voluntary cross-sectional, mixed-methods online survey of consultant emergency physicians and advanced trainees of the ACEM, conducted between December 2011 and March 2012. Results: Eight hundred and fifty-six ACEM members responded to the survey - a response rate of 33%. A similar number of consultants (70%) and trainees (75%) believed public health initiatives should be provided in the ED. Barriers identified by a similar majority of consultants and trainees to the implementation of public health interventions in EDs included dedicated time available for staff to be involved; available public health resources; available funding; clinical staff skills and expertise in public health; and the availability of staff training. Conclusions: Public health and health promotion are perceived by the majority of emergency medicine physicians as important in emergency medicine; however, substantial barriers exists to their implementation. Development of an evidence-based approach to public health interventions, which are effective and feasible in the ED environment, will facilitate a more comprehensive approach to public health initiatives in emergency medicine.

    ABSTRACT: The Victorian Nurse-On-Call (NOC) service has been in use for over 8 years, though little research has been conducted investigating the service. The present study aimed to explore whether parents in Victoria presenting with their child to the ED for lower urgency conditions use the NOC before ED arrival and whether the advice given impacts their decision to attend the ED. A survey study of 1150 parents attending one of four EDs in Victoria, Australia for their child's lower urgency condition. Few parents (20%) contacted the service before attending. Of those who did contact the service, 70% were instructed to attend the ED. Parents reported that they did not contact the service due to lack of awareness (16%) and because they perceive the service to not be helpful (53%). The findings of our study show that use and awareness of NOC is low in parents attending the ED for their child's lower urgency condition. The success of NOC in the goal of deferring non-urgent conditions from presenting to the ED appears limited. Telenursing triage services in Australia should consider assessment of their algorithms to increase the likelihood that where appropriate, lower urgency conditions are directed to primary care services rather than the ED. © 2015 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    ABSTRACT: Objective The objective of the present study is to develop new multifaceted interventions to reduce return visits (RVs) based on identified risk factors related to RVs in the ED and to compare the RV rate before and after the implementation of the intervention.Methods The present study was a controlled before and after study that was conducted in the ED of a 900-bed tertiary hospital in an urban area. The primary outcome was the rate of unplanned RVs to the ED and hospital admission after RV. The risk and predictive factors of RVs were identified by a retrospective study of all unscheduled RVs to the ED within 72 h in 2011. We developed five new multifaceted interventions based on the results: (i) daily RV feedback; (ii) prescription set of drugs; (iii) creation of a discharge instruction sheet; (iv) early follow-up appointments of outpatient department (OPD); and (v) enhancement of referral system. A prospective interventional study in which the interventions were implemented was then conducted over 10 months, from 1 June 2012 to 31 March 2013.ResultsThe five new multifaceted interventions significantly reduced the mean early RV rate and RV admission rate after ED discharge by an average of approximately 25%, with a maximum of approximately 55% and 47%, respectively, compared with the pre-intervention period (RV rate: P < 0.001, RV admission rate: P < 0.001).Conclusions Multifaceted interventions based on identified risk factors for early RV after ED discharge had a positive effect on reducing RVs and the admission rate after RVs for adult patients within 72 h of non-traumatic ED visits.

    ABSTRACT: The crisis of medical response caused by catastrophic events might significantly affect emergency response, and might even initiate more serious social crisis. Therefore, early identification and timely blocking the formation of crisis in the early phase after a major disaster will improve the efficiency of medical response in a major disaster and avoid serious consequences. In the present paper, we described the emergency strategy to crisis management of medical response after a major disaster. Major catastrophic events often lead to various crises, including excess demand, the crisis of response in barrier and the structural crisis in response. The corresponding emergency response strategies include: (i) shunt of catastrophic medical surge; (ii) scalability of medical surge capacity; (iii) matching of the structural elements of response; (iv) maintaining the functions of support system for medical response and maximising the operation of the integrated response system; and (v) selection of appropriate care 'standard' in extreme situations of overload of disaster medical surge. In conclusion, under the impact of a major catastrophic event, medical response is often complex and the medical surge beyond the conventional response capacity and it is easy to be in crisis. In addition to the current consensus of disaster response, three additional aspects should be considered. First, all relevant society forces led by the government and military should be linkages. Second, a powerful medical response system must be based on a strong support system. Third, countermeasures of medical surge should be applied flexibly to the special and specific disaster environment, to promote the effective medical response force. © 2015 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    ABSTRACT: Objective To determine the accuracy and reliability of triage of children in public hospital EDs using the Australasian Triage Scale (ATS). This is the first study to examine these issues in paediatric triage following the 2007 development of the Emergency Triage Education Kit (ETEK) to foster accurate and consistent application of the ATS.MethodsA convenience sample of 167 triage nurses working at three general hospitals and one speciality paediatric hospital in greater metropolitan Melbourne assigned triage ratings for nine paediatric clinical scenarios using the ATS. Scenarios were derived from the ETEK or from other published sources. Kappa was used to assess interrater reliability within and between hospitals.ResultsTriage nurses correctly assigned triage scores to an average of 5.3 of nine paediatric clinical scenarios. Accuracy in specific hospitals ranged from a low of 15% on one scenario, to 100% accuracy on a different scenario at a different hospital. Interrater reliability within and across the EDs studied was found to be kappa = 0.27. Both accuracy and interrater reliability were marginally higher at the speciality paediatric hospital.Conclusions Our findings demonstrate inconsistencies in the accuracy and reliability in which sick children presenting to EDs receive triage scores both within and across hospitals. These results suggest the need for improvements either in current triage nurse training or training resources. Use of the ETEK alone has not resulted in high levels of paediatric triage accuracy or reliability.

    ABSTRACT: The prevalence of allergic disorders is rising, with a corresponding increase in patients presenting to an ED with anaphylaxis. Appropriate follow up is required for patients with anaphylaxis. We reviewed two potential performance indicators for the quality of post-discharge care: (i) the rate of self-injectable adrenaline prescription; and (ii) the referral rate for follow-up care with allergy specialists. A search of Cochrane Library, PubMed and Google Scholar was performed using the following initial search string: anaphylaxis and 'emergency department'. We considered any (interventional or observational design) study assessing post-discharge care in anaphylaxis, measured by either adrenaline self-injection prescription or allergist referral. Subjects were patients with (suspected) anaphylaxis or severe allergic reaction, with no age limit. This review summarises findings from 16 relevant papers, all retrospective analyses of post-discharge care for anaphylaxis. Weighted arithmetic means were calculated for rates of prescription of adrenaline auto-injector and referral to an allergist following admission to an ED in patients with (suspected) anaphylaxis or severe allergic reaction. Prescription rates for self-injected adrenaline at the time of discharge following anaphylaxis varied from 0% to 68%, with a mean of 44%. Allergist referral rates ranged from 0% to 84%, with a mean of 33%. This review demonstrates that there is room for improvement in post-discharge care for patients who present to the ED with an anaphylactic reaction. © 2015 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    ABSTRACT: Damage control resuscitation (DCR) has become a more widely adopted acute management strategy over the past decade. A cornerstone of this strategy is the performance of an initial limited surgical intervention for the control of active bleeding and contamination. This technique is indicated where significant physiological compromise exists and immediate surgical intervention is required. This damage control surgery itself is completed judiciously to allow a period of resuscitative stabilisation before later definitive surgical solutions. This discussion describes the three further principles of DCR and then explores the rationale and drivers behind the development of this approach. © 2015 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.
