    ABSTRACT: We examined the disposition and outcomes of patients presenting to the ED with symptoms suggestive of acute coronary syndrome undergoing measurement of troponin T using a highly sensitive assay. Troponin T (TnT) was measured in 204 consecutive patients (mean age = 65 [±18] years, 55% men) presenting to the ED with symptoms suggestive of acute coronary syndrome. Ninety-four patients predominantly had chest pain, 34 had dyspnoea and the remainder had various symptoms. Overall, 96 patients had TnT >14 ng/L (upper reference limit), of whom 31 were admitted to the cardiology service (26 had final cardiac diagnosis [five ST-elevation MI, 10 non-ST-elevation MI, one unstable angina and 10 other cardiac]). Among these 96 patients, 41 had chronic kidney disease, 17 had heart failure and seven had sepsis. At 30 days, death rates among patients who had TnT >14 ng/L with non-cardiac diagnoses and in patients who had TnT >14 ng/L with a cardiac diagnosis were 6.6% and 2.9% (P = 0.652); no death and/or MI occurred in patients with normal TnT levels. At late follow up (median 6.8 months) that was obtained in 189 (93% of 204) patients, four had MI and 14 died (three cardiac deaths). Despite high-sensitivity TnT assay having a high sensitivity and specificity for myocardial necrosis, the majority of unselected consecutive patients attending ED in whom TnT levels were elevated did not have an acute coronary syndrome. Our pilot study suggests that a larger study is needed to provide evidence to modify management algorithms. © 2015 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    ABSTRACT: To determine the prevalence and nature of off-label and unlicenced (off-label/unlicenced) medicine administration to paediatric ED patients. We undertook a retrospective, observational study in six EDs (July 2011 to June 2012, inclusive). Patients, aged 0-17 years, who were administered a medicine in the ED were included. At each site, 50 eligible patients were randomly selected each month of the study period. An explicit review of each patient's records was undertaken. Medicines were classified as on or off-label/unlicenced according to categories of use approved by the Therapeutic Goods Administration. There were 3343 patients enrolled (56.5% men, mean ± SD age 6.7 ± 5.4 years). Of the 6786 medicine doses administered, 2072 (30.5%, 95% CI 29.4-31.7%) were off-label/unlicenced. The off-label/unlicenced doses were administered to 1213 (36.3%, 95% CI 34.7-37.9%) patients. Patients administered an off-label/unlicenced medicine were younger than those who were not (P < 0.01). Salbutamol, ondansetron, ipratropium, fentanyl and oxycodone were the medicines most commonly administered off-label. In 910 (44.0%) cases, the dose/frequency was not approved; in 592 (28.6%), there was an unapproved indication for treatment; in 158 (7.6%), the medicine was administered via an unapproved route; in 154 (7.4%) the medicine was not approved for the weight or age; and in 74 (3.5%) an unlicenced product was administered. The remaining cases had combinations of reasons. Off-label/unlicenced medicine administration is common. A registry of commonly used off-label medicines is recommended in which the safety and efficacy of their off-label use have been demonstrated by published evidence. © 2015 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    ABSTRACT: Critical illness intersects with the workload of rural doctors in Australia, mostly via their on-call responsibilities to rural hospitals. A significant proportion of these are prehospital incidents - vehicle crashes, farming injuries, bushfire etc. Effective care for such patients requires an integration of prehospital ambulance services, retrieval services and tertiary level trauma services all the way through to rehabilitation. Ambulance services in rural areas are often volunteer based, and with increasing remoteness via the 'tyranny of distance' comes the likelihood of increased delay in arrival of specialist retrieval services. Potential exists to utilise rural clinicians to respond to prehospital incidents in certain defined circumstances, as suggested by a recent survey of rural doctors. © 2015 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    ABSTRACT: Residents from aged care facilities make up a considerable proportion of ED presentations. There is evidence that many residents transferred from aged care facilities to EDs could be managed by primary care services. The present study aimed to describe the characteristics of residents transferred from residential aged care facilities to EDs, and to evaluate the appropriateness and cost of these presentations. A retrospective review of ED records was undertaken for residents transferred from residential aged care facilities to two EDs in Melbourne, Victoria, in 2012. Data examined included residents' mode and time of arrival to ED, presenting complaint, triage category, procedures within ED, diagnosis, length of stay, and disposition. Data were examined against a previously established tool to identify resident transfers that might be 'potentially avoidable'. There were 2880 resident transfers included in the sample, of which 408 transfers were randomly selected for scrutiny of documentation. Seventy-one residents (17.4%) were identified as being potentially avoidable transfers. Many resident transfers might have been avoided with better primary care services in place. Future strategies to improve resident care might include aged care staff skill mix and the availability of outreach or primary care services. © 2015 The Authors.

    ABSTRACT: The primary aim was to investigate staff experiences and attitudes towards palliative care provision in a public metropolitan ED. Using a previously validated survey tool, data were collected from ED clinical staff using Likert-type, open-ended and dichotomous items asking about perceptions of palliative care and education needs. Comparisons were made between nursing and medical staff. Medical staff and nurses' perceptions of palliative care were similar, differing on only 10 of 37 (Likert) items. All staff reported confidence with symptom management, whereas medical staff felt more confident with decision-oriented communication and nurses were more supportive of nasogastric feeding. Staff were moderately accurate in determining the five most common causes of death. Four out of five conditions selected as appropriate for palliative care were cancer diagnoses. End-of-life communication and ethical issues were the two most frequently requested areas for further education. Our study suggests that overall ED staff were confident regarding symptom management in palliative care. Cancer diagnoses were overrepresented in both the top five causes of death and conditions most appropriate for a palliative approach, suggesting that staff might underestimate the role of a palliative approach in non-cancer diagnoses. Areas suggested for further education include communication and ethical issues surrounding end-of-life care. © 2015 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    ABSTRACT: The present study aimed to determine the relationship between the triage-based resource allocation and clinical treatment (TRACT) protocol and mortality and length of stay (LOS) in ED. This before-and-after study was conducted in an adult, tertiary, teaching hospital ED from August 2008 to July 2012. Patients who were younger than 18 years of age, who were dead on arrival and whose triage information was not available were excluded. TRACT was implemented in August 2010, and the Emergency Severity Index (ESI) was used for triage. Primary and secondary outcomes were ED mortality and ED LOS. Multivariate logistic regression models for ED mortality and multivariable general linear models on the ED LOS were used to compare the before- and after-intervention periods. For the 155 563 visits over study period, the ED mortality rate was 0.2%, and the ED LOS was 4.6 h (median). The adjusted odds ratios (95% confidence intervals [CIs]) of the TRACT protocol on ED mortality were 0.69 (0.54-0.88) for total patients, 0.42 (0.30-0.59) for ESI 1, 1.04 (0.66-1.65) for ESI 2 and 1.45 (0.76-2.75) for ESI 3 group. The adjusted coefficients (95% CIs) of the TRACT on the ED LOS were -88.1 (-96.9 ∼ -79.2) min for all patients, -44.9 (-72.0 ∼ -17.9) min for ESI level 2 and -104.3 (-114.7 ∼ -94.0) min for ESI level 3. The TRACT protocol decreased the ED mortality in ESI 1 group and reduced the ED LOS in ESI levels 2 and 3 groups. © 2015 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    ABSTRACT: In critical care medicine, US views of the inferior vena cava (IVC) and its change with respiration are used to estimate the intravascular volume status of unwell patients and, in particular, to answer the question: 'Is this patient likely to be fluid responsive?' Most commonly in the literature, the subxiphisternal (SX) window in the longitudinal plane is utilised. To date, no study has specifically assessed interrater agreement in estimating IVC diameter between emergency medicine specialists (experts) and trainees (learners). To determine the interrater agreement between an expert (senior emergency specialist with US qualifications) and learner (emergency medicine trainee) when measuring IVC diameter (IVCD) and IVC collapsibility index (IVCCI) in the SX longitudinal US window in healthy volunteers. Healthy volunteers (ED staff) were scanned in the supine position using a sector (cardiac) probe of a portable US machine, in the SX longitudinal position. The maximum and minimum diameters of the IVC were measured in each of these positions and the IVCCI calculated. Results were analysed using Bland-Altman plots. In the longitudinal SX window, the operators' measurements of maximum IVCD differed by an average of 1.9 mm (95% limits of agreement -9.4 mm to +5.5 mm) and their measurement of IVCCI differed by an average of 4% (95% limits of agreement -30% to 38%). The wide 95% limits of agreement demonstrate a poor interrater agreement between the IVC US measurements obtained by expert and learner users in the assessment of fluid status. These ranges are greater than clinically acceptable. © 2015 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    ABSTRACT: The objective was to evaluate the impact of an ED clinical redesign project that involved team-based care and early senior assessment on hospital performance. This was an interrupted time series analysis performed using daily hospital performance data 6 months before and 8 months after the implementation of the clinical redesign intervention that involved Emergency Consultant-led team-based care, redistribution of ED beds and implementation of a senior nursing coordination roles in the ED. The primary outcome was the daily National Emergency Access Target (NEAT) performance (proportion of total daily ED presentations that were admitted to an inpatient ward or discharged from ED within 4 h of arrival). Secondary outcomes were daily ALOS in ED, inpatient Clinical Emergency Response System (CERS) calls and hospital mortality. Autoregressive Integrated Moving Average analysis was used to model NEAT performance. Hospital mortality was modelled using negative binomial regression. After adjusting for patient volume, inpatient admissions, ambulance, hospital occupancy, weekends ED Consultant numbers, weekends and underlying trends, there was a 17% improvement in NEAT associated with the post-intervention period (95% CI 12, 19% P < 0.001). There was no change in the number of CERS calls and the median daily hospital mortality rate reduced from 1.04% to 0.96% (P = 0.025). An ED-focused clinical redesign project was associated with a 17% improvement in NEAT performance with no evidence of an increase in clinical deterioration on inpatient wards and evidence for an improvement in hospital mortality. © 2015 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    ABSTRACT: To describe population-based trends in cycling-related presentations to EDs over the past decade. A retrospective cohort of road trauma patients (motor vehicle, motor cyclist, cyclist and pedestrian) presenting to EDs in the Sydney Greater Metropolitan Area between 2004 and 2013 was obtained using the Public Health Real-time Emergency Department Surveillance System. The outcomes of interest were the cycling-related ED presentation rate per 1000 population, as well as the proportion of cycling-related presentations that died in ED or were admitted to a critical care ward. Trends in ED presentation rates based on presentation counts and Sydney population data were plotted and described. There were 68 438 cycling-related presentations identified, representing 30% of all road trauma patients presenting to EDs in Sydney. There was a 91% increase in cycling-related presentations for the 35 to 64-year-old age group and a 123% increase in cycling-related presentations in the 65-year-old and over age group. All other age groups were associated with a stable or decrease in cycling-related ED presentation rates. The proportion of presentations requiring critical care ward admission or death in ED has decreased by 20%. Using an ED syndromic surveillance system, cycling-related ED presentation rates in Sydney Australia have increased in those aged 35 years and over the past 10 years, with a relative decrease in the proportion of deaths in ED or those requiring critical care admission. © 2015 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.
