RESUMO
OBJECTIVES: To describe the epidemiology and outcomes of non-traumatic dyspnoea in patients aged 75 years or older presenting to emergency departments (EDs) in the Asia-Pacific region. METHODS: A substudy of a prospective interrupted time series cohort study conducted at three time points in EDs in Australia, New Zealand, Singapore, Hong Kong and Malaysia of patients presenting to the ED with dyspnoea as a main symptom. Data were collected over three 72-h periods and included demographics, co-morbidities, mode of arrival, usual medications, ED investigations and treatment, ED diagnosis and disposition, and outcome. The primary outcomes of interest are the epidemiology and outcome of patients aged 75 years or older presenting to the ED with dyspnoea. RESULTS: 1097 patients were included. Older patients with dyspnoea made up 1.8% [95% confidence interval (CI) 1.7-1.9%] of ED presentations. The most common diagnoses were heart failure (25.3%), lower respiratory tract infection (25.2%) and chronic obstructive pulmonary disease (17.6%). Hospital ward admission was required for 82.6% (95% CI 80.2-84.7%), with 2.5% (95% CI 1.7-3.6%) requiring intensive care unit (ICU) admission. In-hospital mortality was 7.9% (95% CI 6.3-9.7%). Median length of stay was 5 days (interquartile range 2-8 days). CONCLUSION: Older patients with dyspnoea make up a significant proportion of ED case load, and have a high admission rate and significant mortality. Exacerbations or worsening of pre-existing chronic disease account for a large proportion of cases which may be amenable to improved chronic disease management.

BACKGROUND AND OBJECTIVE: Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is a common presentation to emergency departments (ED) but data regarding its epidemiology and outcomes are scarce. We describe the epidemiology, clinical features, treatment and outcome of patients treated for AECOPD in ED. METHODS: This was a planned sub-study of patients with an ED diagnosis of AECOPD identified in the Asia, Australia and New Zealand Dyspnoea in Emergency Departments (AANZDEM) study. The AANZDEM was a prospective, interrupted time series cohort study conducted in 46 ED in Australia, New Zealand, Singapore, Hong Kong and Malaysia over three 72-h periods in May, August and October 2014. Primary outcomes were patient epidemiology, clinical features, treatment and outcomes (hospital length of stay (LOS) and mortality). RESULTS: Forty-six ED participated. There were 415 patients with an ED primary diagnosis of AECOPD (13.6% of the overall cohort; 95% CI: 12.5-14.9%). Median age was 73 years, 60% males and 65% arrived by ambulance. Ninety-one percent had an existing COPD diagnosis. Eighty percent of patients received inhaled bronchodilators, 66% received systemic corticosteroids and 57% of those with pH < 7.30 were treated with non-invasive ventilation (NIV). Seventy-eight percent of patients were admitted to hospital, 7% to an intensive care unit. In-hospital mortality was 4% and median LOS was 4 days (95% CI: 2-7). CONCLUSION: Patients treated in ED for AECOPD commonly arrive by ambulance, have a high admission rate and significant in-hospital mortality. Compliance with evidence-based treatments in ED is suboptimal affording an opportunity to improve care and potentially outcomes.

BACKGROUND: Early goal-directed therapy (EGDT) has been endorsed in the guidelines of the Surviving Sepsis Campaign as a key strategy to decrease mortality among patients presenting to the emergency department with septic shock. However, its effectiveness is uncertain. METHODS: In this trial conducted at 51 centers (mostly in Australia or New Zealand), we randomly assigned patients presenting to the emergency department with early septic shock to receive either EGDT or usual care. The primary outcome was all-cause mortality within 90 days after randomization. RESULTS: Of the 1600 enrolled patients, 796 were assigned to the EGDT group and 804 to the usual-care group. Primary outcome data were available for more than 99% of the patients. Patients in the EGDT group received a larger mean (±SD) volume of intravenous fluids in the first 6 hours after randomization than did those in the usual-care group (1964±1415 ml vs. 1713±1401 ml) and were more likely to receive vasopressor infusions (66.6% vs. 57.8%), red-cell transfusions (13.6% vs. 7.0%), and dobutamine (15.4% vs. 2.6%) (P<0.001 for all comparisons). At 90 days after randomization, 147 deaths had occurred in the EGDT group and 150 had occurred in the usual-care group, for rates of death of 18.6% and 18.8%, respectively (absolute risk difference with EGDT vs. usual care, -0.3 percentage points; 95% confidence interval, -4.1 to 3.6; P=0.90). There was no significant difference in survival time, in-hospital mortality, duration of organ support, or length of hospital stay. CONCLUSIONS: In critically ill patients presenting to the emergency department with early septic shock, EGDT did not reduce all-cause mortality at 90 days.

STUDY OBJECTIVE: Communication is commonly understood by health professional researchers to consist of relatively isolated exchanges of information. The social and organizational context is given limited credit. This article examines the significance of the environmental complexity of the emergency department (ED) in influencing communication strategies and makes the case for adopting a richer understanding of organizational communication. METHODS: This study draws on approximately 12 months (1,600 hours) of ethnographic observations, yielding approximately 4,500 interactions across 260 clinicians and staff in the EDs of 2 metropolitan public teaching hospitals in Sydney, Australia. RESULTS: The study identifies 5 communication competencies of increasing complexity that emergency clinicians need to accomplish. Furthermore, it identifies several factors-hierarchy, formally imposed organizational boundaries and roles, power, and education-that contribute to the collective function of ensuring smooth patient transfer through and out of the ED. These factors are expressed by and shape external communication with clinicians from other hospital departments. CONCLUSION: This study shows that handoff of patients from the ED to other hospital departments is a complex communication process that involves more than a series of "checklistable" information exchanges. Clinicians must learn to use both negotiation and persuasion to achieve objectives.

STUDY OBJECTIVE: We determine whether emergency physician-provided deep sedation with 1:1 ketofol versus propofol results in fewer adverse respiratory events requiring physician intervention when used for procedural sedation and analgesia. METHODS: Consenting patients requiring deep sedation were randomized to receive either ketofol or propofol in a double-blind fashion according to a weight-based dosing schedule. The primary outcome was the occurrence of a respiratory adverse event (desaturation, apnea, or hypoventilation) requiring an intervention by the sedating physician. Secondary outcomes included hypotension and patient satisfaction. RESULTS: Five hundred seventy-three patients were enrolled and randomized, 292 in the propofol group and 281 in the ketofol group. Five percent in the propofol group and 3% in the ketofol group met the primary outcome, an absolute difference of 2% (95% confidence interval [CI] -2% to 5%). Patients receiving propofol were more likely to become hypotensive (8 versus 1%; difference 7%; 95% CI 4% to 10%). Patient satisfaction was very high in both groups (10/10; interquartile range 10 to 10/10), and although the ketofol group was more likely to experience severe emergence delirium (5% versus 2%; difference 3%; 95% CI 0.4% to 6%), they had lower pain scores at 30 minutes postprocedure. Other secondary outcomes were similar between groups. CONCLUSION: Ketofol and propofol resulted in a similar incidence of adverse respiratory events requiring the intervention of the sedating physician. Although propofol resulted in more hypotension, the clinical relevance of this is questionable, and both agents are associated with high levels of patient satisfaction.

BACKGROUND: Exacerbations of chronic obstructive pulmonary disease (COPD) are common in emergency departments (ED). Guidelines recommend administration of inhaled bronchodilators, systemic corticosteroids and antibiotics along with non-invasive ventilation (NIV) for patients with respiratory acidosis. AIM: To determine compliance with guideline recommendations for patients treated for COPD in ED in Europe (EUR) and South East Asia/Australasia (SEA) and to compare management and outcomes. METHODS: In each region, an observational prospective cohort study was performed that included patients presenting to ED with the main complaint of dyspnoea during three 72-h periods. This planned sub-study included those with an ED primary discharge diagnosis of COPD. Data were collected on demographics, clinical features, treatment, disposition and in-hospital mortality. We determined overall compliance with guideline recommendations and compared treatments and outcome between regions. RESULTS: A total of 801 patients was included from 122 ED (66 EUR and 46 SEA). Inhaled bronchodilators were administered to 80.3% of patients, systemic corticosteroids to 59.5%, antibiotics to 44 and 60.6% of patients with pH <7.3 received NIV. The proportion administered systemic corticosteroids was higher in SEA (EUR vs SEA for all comparisons; 52 vs 66%, P < 0.001) as was administration of antibiotics (40 vs 49%, P = 0.02). Rates of NIV and mechanical ventilation were similar. Overall in-hospital mortality was 4.2% (SEA 3.9% vs EUR 4.5%, P = 0.77). CONCLUSION: Compliance with guideline recommended treatments, in particular administration of corticosteroids and NIV, was sub-optimal in both regions. Improved compliance has the potential to improve patient outcome.

BACKGROUND: Prospective human studies of anaphylaxis and its mechanisms have been limited, with few severe cases or examining only 1 or 2 mediators. OBJECTIVES: We wanted to define the clinical patterns of anaphylaxis and relationships between mediators and severity. METHODS: Data were collected during treatment and before discharge. Serial blood samples were taken for assays of mast cell tryptase, histamine, anaphylatoxins (C3a, C4a, C5a), cytokines (IL-2, IL-6, IL-10), soluble tumor necrosis factor receptor I, and platelet activating factor acetyl hydrolase. Principal component analysis defined mediator patterns, and logistic regression identified risk factors and mediator patterns associated with reaction severity and delayed reactions. RESULTS: Of 412 reactions in 402 people, 315 met the definition for anaphylaxis by the National Institute of Allergy and Infectious Diseases/Food Allergy and Anaphylaxis Network. Of 97 severe reactions 45 (46%) were hypotensive, 23 (24%) were hypoxemic, and 29 (30%) were mixed. One patient died. Severe reactions were associated with older age, pre-existing lung disease, and drug causation. Delayed deteriorations treated with epinephrine occurred in 29 of 315 anaphylaxis cases (9.2%) and were more common after hypotensive reactions and with pre-existing lung disease. Twenty-two of the 29 delayed deteriorations (76%) occurred within 4 hours of initial epinephrine treatment. Of the remaining 7 cases, 2 were severe and occurred after initially severe reactions, within 10 hours. All mediators were associated with severity, and 1 group (mast cell tryptase, histamine, IL-6, IL-10, and tumor necrosis factor receptor I) was also associated with delayed deteriorations. Low platelet activating factor acetyl hydrolase activity was associated with severe reactions. CONCLUSION: The results suggest that multiple inflammatory pathways drive reaction severity and support recommendations for safe observation periods after initial treatment.

BACKGROUND: Patients with paroxysmal supraventricular tachycardia frequently present to the Emergency Department. Where vagal manoeuvres fail, the two most commonly used drugs are adenosine and calcium channel antagonists. Both are known to be effective but both have a significant side-effect profile. OBJECTIVES: To examine the relative effects of adenosine and calcium channel antagonists and, if possible, to determine which is most appropriate for the management of supraventricular tachycardia. SEARCH METHODS: Studies were identified from The Cochrane Central Register of Controlled Trials (CENTRAL) on The Cochrane Library, Issue 2, 2010, MEDLINE (1966 to May Week 1 2010) and EMBASE (1980 to 2010 week 19). The searches were originally run in June 2006 and updated and re-run in May 2010. Bibliographies of identified studies were also examined. No language restrictions were applied. SELECTION CRITERIA: Randomised trials comparing adenosine and a calcium channel antagonist in patients of any age with supraventricular tachycardia, where one of the defined outcomes was reported. Outcomes of interest were: reversion rate, mortality, time to reversion, rate of relapse, major and minor adverse events, length of hospital stay and patient satisfaction. DATA COLLECTION AND ANALYSIS: Two authors independently checked the results of searches to identify relevant studies. Dichotomous outcomes were reported as Peto Odds ratios and continuous outcomes as weighted mean differences. MAIN RESULTS: A total of ten trials were identified (two new trials were identified through the updated search in May 2010), all of which used verapamil as the calcium antagonist. In the pooled analysis there was no significant difference in reversion rate between the two drugs. Time to reversion was slower for verapamil than adenosine in all studies that reported this outcome, but the data were not suitable for combining. Relapse rates were higher for adenosine compared with verapamil (OR 0.25, 95% CI 0.07 to 0.99. P=0.05). Minor adverse events such as nausea, chest tightness, shortness of breath and headache were reported much more frequently in patients treated with adenosine with 10.8 % of patients reporting at least one of these events, compared with 0.6% of those treated with verapamil (OR 0.15, 95% CI 0.09 to 0.26, P<0.001). Hypotension was reported exclusively in the verapamil treatment group (4/214), and occurred in none of the patients treated with adenosine (OR 10.8, 95% CI 1.46 to 80.22, P=0.02). AUTHORS' CONCLUSIONS: Adenosine and verapamil are both effective treatments for supraventricular tachycardia in the majority of patients. There is a high incidence of minor but unpleasant side effects and a greater risk of relapse in patients treated with adenosine while some patients treated with verapamil may develop significant hypotension. Patients should be fully informed of these risks prior to treatment.

OBJECTIVES: To determine issues that affect newly resettled refugees in accessing an emergency department (ED). DESIGN, SETTING AND PARTICIPANTS: We conducted a descriptive community survey using a semistructured questionnaire. Newly resettled refugees from the Middle East and Africa were interviewed, statistical analysis was performed, and standard content analysis methods were applied to free-text responses. MAIN OUTCOME MEASURES: Emergency health-seeking behaviour, sociocultural barriers and beliefs about Australia's emergency health services. RESULTS: Half the African refugees (53/106) (50%), compared with only 15/49 (31%) of the Middle Eastern refugees, preferred an ED service over other forms of care for an urgent medical condition (P = 0.024). Qualitative data revealed that most newly resettled refugees understand how to use the emergency health services. However, while most indicated that they were able to make a call for emergency medical help, a substantial number of our respondents revealed that they were afraid to make such a call for fear of security implications, on the basis of experiences from their home countries. CONCLUSION: Reasons for differences in preferences of health care access, and determining how best to educate the community on the use of ED services, warrant further investigation. From a policy perspective, the increasing health care needs of refugees need re-examination when planning health care provision to refugees.

Basilar artery occlusion (BAO) is a rare cause of paediatric stroke that may result in severe neurological disability including a 'locked-in' state. Acute interventional therapy for paediatric BAO is limited to a small number of published case reports. Of 13 previously published cases that have undergone acute intravascular therapy, six made a full neurological recovery, six had residual deficits ranging from mild dysarthria and ataxia to vegetative state and one patient died. The time from symptom onset to intervention was ≥ 12 h in 77% (10/13). We reported a 14-year-old female patient presenting with altered sensorium that progressed to a 'locked-in' state due to idiopathic BAO who made a full clinical recovery after successful mechanical thrombectomy at 24 h following symptom onset. Acute neuro-interventional therapy for paediatric BAO can result in complete neurological recovery despite the presence of severe neurological deficits and a prolonged period of time from symptom onset to clinical diagnosis.

Automatic devices are used to take postural blood pressures in the emergency department despite research proving their inaccuracy in taking single blood pressures. This study assessed the accuracy of an automatic device compared with a manual aneroid reference standard for determining orthostatic hypotension and postural drops at triage. Supine and standing blood pressures were taken with an automatic and a manual device in a sequential and random order, and postural drops were calculated. The manual device indicated 10/150 emergency department patients had orthostatic hypotension (7%) and the automatic device detected this with a sensitivity of 30% and a specificity of 91%. The automatic-manual differences were clinically significant in 13% of systolic drops and 37% of diastolic drops. Findings suggest that automatic devices cannot reliably detect or rule out orthostatic hypotension, indicating that triage nurses need to use manual devices to take accurate postural blood pressures for optimal patient care.

OBJECTIVE: Lower respiratory tract infection (LRTI) is a frequent cause of dyspnoea in EDs, and is associated with considerable morbidity and mortality. We described and compared the management of this disease in Europe and Oceania/South-East Asia (SEA) cohorts. METHODS: We conducted a prospective cohort study with three time points in Europe and Oceania/SEA. We included in this manuscript patients presenting to EDs with dyspnoea and a diagnosis of LRTI in ED. We collected comorbidities, chronic medication, clinical signs at arrival, laboratory parameters, ED management and patient outcomes. RESULTS: A total of 1389 patients were included, 773 in Europe and 616 in SEA. The European cohort had more comorbidities including chronic heart failure, obesity, chronic obstructive pulmonary disease and smoking. Levels of inflammatory markers were higher in Europe. There were more patients with inflammatory markers in Europe and more hypercapnia in Oceania/SEA. The use of antibiotics was higher in SEA (72.2% vs 61.8%, P < 0.001) whereas intravenous diuretics, non-invasive and invasive ventilation were higher in Europe. Intensive care unit admission rate was 9.9% in Europe cohort and 3.4% in Oceania/SEA cohort. ED mortality was 1% and overall in-hospital mortality was 8.7% with no differences between regions. CONCLUSIONS: More patients with LRTI in Europe presented with cardio-respiratory comorbidities, they received more adjunct therapies and had a higher intensive care unit admission rate than patients from Oceania/SEA, although mortality was similar between the two cohorts.

BACKGROUND: Anaphylaxis is generally unanticipated and requires emergency management. Therefore, the biological mediators in human beings have been difficult to define. OBJECTIVE: Our aim was to identify cytokines and chemokines whose concentrations increase during anaphylaxis in human beings and to determine how each correlates with severity. METHODS: We measured the concentrations of potential mediators, including cytokines, chemokines, mast cell tryptase (MCT), and histamine, over 3 time points in 76 patients presenting to emergency departments with anaphylaxis and correlated these with a global severity scale, hypotension, and hypoxia. RESULTS: IL-2, IL-6, IL-10, TNF receptor I, MCT, and histamine were significantly elevated in patients with severe reactions (n = 36) compared with moderate reactions (n = 40) and healthy controls. Histamine levels peaked at emergency department arrival, whereas other mediators peaked later. IL-4, IL-5, IL-13, IFN-gamma, and TNF-alpha were marginally elevated in severe reactions compared with healthy controls but did not correlate with reaction severity. Severe reactions tended to be either hypotensive (n = 19) or hypoxemic (n = 12). Levels of IL-6, IL-10, TNF receptor I, MCT, and histamine correlated with hypotension. No mediator correlated with hypoxemia or other respiratory features. CONCLUSION: This study confirms that the concentrations of a number of cytokines are elevated in blood during anaphylaxis in human beings and that some correlate with the presence of hypotension. Others were only marginally elevated within a concentration range that available assays do not reliably detect. During respiratory reactions, mediators may be largely confined to the airways so that blood concentrations do not reflect activity.

OBJECTIVES: Guideline recommended treatments for chronic conditions are thought to reduce ED presentations. METHOD: We used data from 1958 ED patients with dyspnoea to describe medication use in patients with chronic conditions. RESULTS: A total of 1233 (63.5%) patients had one or more of: chronic obstructive pulmonary disease 547 (28%), asthma 454 (23%), atrial fibrillation 368 (19%) or heart failure 401 (21%). Approximately, 70% were prescribed appropriate preventative medication for their chronic condition when they presented to ED with dyspnoea. CONCLUSION: Prescription of guideline recommended therapies for chronic conditions in patients presenting to the ED in Australasia with acute dyspnoea is similar or higher than reported previously.

The interdisciplinary context of the emergency department encompasses diverse clinical presentations requiring teamwork by doctors, nurses and allied health workers to achieve optimal patient care. This interdisciplinary focus is extended by adding a research perspective. This project sought to systematically examine the current research capacity of emergency department staff at a major Australian tertiary urban hospital and to derive information about further research-related needs with a view to enhancing research capacity. The mixed method project utilized a department-wide staff survey followed by focus groups and individual interviews. Adequate response rates to the two phases were achieved (n = 67, n = 17 respectively). Not surprisingly, 89% of participants reported that they needed help with developing their research skills. Clinicians reported little or no experience with (i) finding literature (35%) and critical review (50%), (ii) research skills and techniques, both qualitative (72%) and quantitative (63%), and (iii) research output: publishing (68%), writing & presenting (34%). Data from focus groups and individual interviews yielded themes around developing research skills, communication, meaningfulness, team work and interdisciplinary strategies, forming part of the Dimensional Enhancing Research Capacity (DERC) model. This project highlighted not only interdisciplinary needs for research but also the way that research may additionally assist with building interprofessional linkage.

OBJECTIVES: To determine the prevalence of frailty in Emergency Departments (EDs); examine the ability of frailty to predict poor outcomes post-discharge; and identify the most appropriate instrument for routine ED use. METHODS: In this prospective study we simultaneously assessed adults 65+yrs admitted and/or spent one night in the ED using Fried, the Clinical Frailty Scale (CFS), and SUHB (Stable, Unstable, Help to walk, Bedbound) scales in four Australian EDs for rapid recognition of frailty between June 2015 and March 2016. RESULTS: 899 adults with complete follow-up data (mean (SD) age 80.0 (8.3) years; female 51.4%) were screened for frailty. Although different scales yielded vastly different frailty prevalence (SUHB 9.7%, Fried 30.4%, CFS 43.7%), predictive discrimination of poor discharge outcomes (death, poor self-reported health/quality of life, need for community services post-discharge, or reattendance to ED after the index hospitalization) for all identical final models was equivalent across all scales (AUROC 0.735 for Fried, 0.730 for CFS and 0.720 for SUHB). CONCLUSION: This study confirms that screening for frailty in older ED patients can inform prognosis and target discharge planning including community services required. The CFS was as accurate as the Fried and SUHB in predicting poor outcomes, but more practical for use in busy clinical environments with lower level of disruption. Given the limitations of objectively measuring frailty parameters, self-report and clinical judgment can reliably substitute the assessment in EDs. We propose that in a busy ED environment, frailty scores could be used as a red flag for poor follow-up outcome.

BACKGROUND: Emergency departments (EDs) are pressured environment where patients with supportive and palliative care needs may not be identified. We aimed to test the predictive ability of the CriSTAL (Criteria for Screening and Triaging to Appropriate aLternative care) checklist to flag patients at risk of death within 3 months who may benefit from timely end-of-life discussions. METHODS: Prospective cohorts of >65-year-old patients admitted for at least one night via EDs in five Australian hospitals and one Irish hospital. Purpose-trained nurses and medical students screened for frailty using two instruments concurrently and completed the other risk factors on the CriSTAL tool at admission. Postdischarge telephone follow-up was used to determine survival status. Logistic regression and bootstrapping techniques were used to test the predictive accuracy of CriSTAL for death within 90 days of admission as primary outcome. Predictability of in-hospital death was the secondary outcome. RESULTS: A total of 1,182 patients, with median age 76 to 80 years (IRE-AUS), were included. The deceased had significantly higher mean CriSTAL with Australian mean of 8.1 (95% confidence interval [CI] = 7.7-8.6) versus 5.7 (95% CI = 5.1-6.2) and Irish mean of 7.7 (95% CI = 6.9-8.5) versus 5.7 (95% CI = 5.1-6.2). The model with Fried frailty score was optimal for the derivation (Australian) cohort but prediction with the Clinical Frailty Scale (CFS) was also good (areas under the receiver-operating characteristic [AUROC] = 0.825 and 0.81, respectively). Values for the validation (Irish) cohort were AUROC = 0.70 with Fried and 0.77 using CFS. A minimum of five of 29 variables were sufficient for accurate prediction, and a cut point of 7+ or 6+ depending on the cohort was strongly indicative of risk of death. The most significant independent predictor of short-term death in both cohorts was frailty, carrying a twofold risk of death. CriSTAL's accuracy for in-hospital death prediction was also good (AUROC = 0.795 and 0.81 in Australia and Ireland, respectively), with high specificity and negative predictive values. CONCLUSIONS: The modified CriSTAL tool (with CFS instead of Fried's frailty instrument) had good discriminant power to improve certainty of short-term mortality prediction in both health systems. The predictive ability of models is anticipated to help clinicians gain confidence in initiating earlier end-of-life discussions. The practicalities of embedding screening for risk of death in routine practice warrant further investigation.

OBJECTIVE: Asthma exacerbations are common presentations to ED. Key guideline recommendations for management include administration of inhaled bronchodilators, systemic corticosteroids and titrated oxygen therapy. Our aim was to compare management and outcomes between patients treated for asthma in Europe (EUR) and South East Asia/Australasia (SEA) and compliance with international guidelines. METHODS: In each region, prospective, interrupted time series studies were performed including adult (age >18 years) patients presenting to ED with the main complaint of dyspnoea during three 72 h periods. This was a planned sub-study that included those with an ED primary diagnosis of asthma. Data was collected on demographics, clinical features, treatment in ED, diagnosis, disposition and in-hospital outcome. The results of interest were differences in treatment and outcome between EUR and SEA cohorts. RESULTS: Five hundred and eighty-four patients were identified from 112 EDs (66 EUR and 46 SEA). The cohorts had similar demographics and co-morbidity patterns, with 89% of the cohort having a previous diagnosis of asthma. There were no significant differences in treatment between EUR and SEA patients - inhaled beta-agonists were administered in 86% of cases, systemic corticosteroids in 66%, oxygen therapy in 44% and antibiotics in 20%. Two thirds of patients were discharged home from the ED. CONCLUSION: The data suggests that compliance with guideline-recommended therapy in both regions, particularly corticosteroid administration, is sub-optimal. It also suggests over-use of antibiotics.

OBJECTIVE: The primary objective of this study was to describe the epidemiology and management of dyspneic patients presenting to emergency departments (EDs) in an international patient population. Our secondary objective was to compare the EURODEM and AANZDEM patient populations. PATIENTS AND METHODS: An observational prospective cohort study was carried out in Europe and the Asia-Pacific region. The study included consecutive patients presenting to EDs with dyspnea as the main complaint. Data were collected on demographics, comorbidities, chronic treatment, clinical signs and investigations, treatment in the ED, diagnosis, and disposition from ED. RESULTS: A total of 5569 patients were included in the study. The most common ED diagnoses were lower respiratory tract infection (LRTI) (24.9%), heart failure (HF) (17.3%), chronic obstructive pulmonary disease (COPD) exacerbation (15.8%), and asthma (10.5%) in the overall population. There were more LRTI, HF, and COPD exacerbations in the EURODEM population, whereas asthma was more frequent in the AANZDEM population. ICU admission rates were 5.5%. ED mortality was 0.6%. The overall in-hospital mortality was 5.0%. In-hospital mortality rates were 8.7% for LRTI, 7.6% for HF, and 5.6% for COPD patients. CONCLUSION: Dyspnea as a symptom in the ED has high ward and ICU admission rates. A variety of causes of dyspnea were observed in this study, with chronic diseases accounting for a major proportion.

BACKGROUND: Cooling of recently amputated digits is recommended to preserve tissue pending reimplantation. Although many methods are describe for cooling digits, it is unknown which method is optimal. METHODS: Six methods were compared in which fresh chicken feet were wrapped in saline-soaked gauze, placed in a plastic bag or a specimen jar, and then placed in a fixed quantity of ice and water in one of a plastic bag, kidney dish, or sealed plastic container. Serial measurements were made of the (1) tissue temperature and (2) point at which ice in the solution was no longer visible. Each method was repeated 12 times, resulting in 72 sets of measurements. RESULTS: There was a significant variation in the time each method took to reach the target tissue temperature (p < 0.001) and the duration that the tissue was kept within the target temperature range (p < 0.001). Of the six methods tested, placing the chicken foot into a specimen jar and subsequently placing this into a specimen bag containing ice and water kept the tissue within the target temperature range (4 degrees C +/- 2 degrees C) for the longest duration [225.8 minutes, 95% confidence intervals (CI), 201.5-250.1]. The Bag-in-kidney dish method performed worst, with the slowest time to reach target temperature (58.0 minutes, 95%CI, 46.0-70.0) and the shortest duration at this temperature (62.0 minutes, 95%CI, 46.3-77.7). CONCLUSION: Of the six methods examined, the best method for achieving a target temperature of 4 degrees C +/- 2 degrees C is by wrapping the tissue in saline-soaked gauze, placing it in a specimen jar and placing this into a specimen bag that contains ice and water.
