RESUMO
STUDY OBJECTIVE: We assess the efficacy and safety of tamsulosin compared with placebo as medical expulsive therapy in patients with distal ureteric stones less than or equal to 10 mm in diameter. METHODS: This was a randomized, double-blind, placebo-controlled, multicenter trial of adult participants with calculus on computed tomography (CT). Patients were allocated to 0.4 mg of tamsulosin or placebo daily for 28 days. The primary outcomes were stone expulsion on CT at 28 days and time to stone expulsion. RESULTS: There were 403 patients randomized, 81.4% were men, and the median age was 46 years. The median stone size was 4.0 mm in the tamsulosin group and 3.7 mm in the placebo group. Of 316 patients who received CT at 28 days, stone passage occurred in 140 of 161 (87.0%) in the tamsulosin group and 127 of 155 (81.9%) with placebo, a difference of 5.0% (95% confidence interval -3.0% to 13.0%). In a prespecified subgroup analysis of large stones (5 to 10 mm), 30 of 36 (83.3%) tamsulosin participants had stone passage compared with 25 of 41 (61.0%) with placebo, a difference of 22.4% (95% confidence interval 3.1% to 41.6%) and number needed to treat of 4.5. There was no difference in urologic interventions, time to self-reported stone passage, pain, or analgesia requirements. Adverse events were generally mild and did not differ between groups. CONCLUSION: We found no benefit overall of 0.4 mg of tamsulosin daily for patients with distal ureteric calculi less than or equal to 10 mm in terms of spontaneous passage, time to stone passage, pain, or analgesia requirements. In the subgroup with large stones (5 to 10 mm), tamsulosin did increase passage and should be considered.

BACKGROUND: Nausea and vomiting is a common and distressing presenting complaint in emergency departments (ED). The aetiology of nausea and vomiting in EDs is diverse and drugs are commonly prescribed. There is currently no consensus as to the optimum drug treatment of nausea and vomiting in the adult ED setting. OBJECTIVES: To provide evidence of the efficacy and safety of antiemetic medications in the management of nausea and vomiting in the adult ED setting. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2014, Issue 8), MEDLINE (OvidSP) (January 1966 to August 2014), EMBASE (OvidSP) (January 1980 to August 2014) and ISI Web of Science (January 1955 to August 2014). We also searched relevant clinical trial registries and conference proceedings. SELECTION CRITERIA: We included randomized controlled trials (RCTs) of any drug in the treatment of nausea and vomiting in the treatment of adults in the ED. Study eligibility was not restricted by language or publication status. DATA COLLECTION AND ANALYSIS: Two review authors independently performed study selection, data extraction and assessment of risk of bias in included studies. We contacted authors of studies to obtain missing information if required. MAIN RESULTS: We included eight trials, involving 952 participants, of which 64% were women. Included trials were generally of adequate quality, with six trials at low risk of bias, and two trials at high risk of bias. Three trials with 518 participants compared five different drugs with placebo; all reported the primary outcome as mean change in visual analogue scale (VAS) (0 to 100) for nausea severity from baseline to 30 minutes. Trials did not routinely report other primary outcomes of the change in nausea VAS at 60 minutes or number of vomiting episodes. Differences in mean VAS change from baseline to 30 minutes between placebo and the drugs evaluated were: metoclopramide (three trials, 301 participants; mean difference (MD) -5.27, 95% confidence interval (CI) -11.33 to 0.80), ondansetron (two trials, 250 participants; MD -4.32, 95% CI -11.20 to 2.56), prochlorperazine (one trial, 50 participants; MD -1.80, 95% CI -14.40 to 10.80), promethazine (one trial, 82 participants; MD -8.47, 95% CI -19.79 to 2.85) and droperidol (one trial, 48 participants; MD -15.8, 95% CI -26.98 to -4.62). The only statistically significant change in baseline VAS to 30 minutes was for droperidol, in a single trial of 48 participants. No other drug was statistically significantly superior to placebo. Other included trials evaluated a drug compared to "active controls" (alternative antiemetic). There was no convincing evidence of superiority of any particular drug compared to active control. All trials included in this review reported adverse events, but they were variably reported precluding meaningful pooling of results. Adverse events were generally mild, there were no reported serious adverse events. Overall, the quality of the evidence was low, mainly because there were not enough data. AUTHORS' CONCLUSIONS: In an ED population, there is no definite evidence to support the superiority of any one drug over any other drug, or the superiority of any drug over placebo. Participants receiving placebo often reported clinically significant improvement in nausea, implying general supportive treatment such as intravenous fluids may be sufficient for the majority of people. If a drug is considered necessary, choice of drug may be dictated by other considerations such as a person's preference, adverse-effect profile and cost. The review was limited by the paucity of clinical trials in this setting. Future research should include the use of placebo and consider focusing on specific diagnostic groups and controlling for factors such as intravenous fluid administered.

BACKGROUND: Bronchiolitis imposes the largest health care burden on non-elective paediatric hospital admissions worldwide, with up to 15 % of cases requiring admission to intensive care. A number of previous studies have failed to show benefit of pharmaceutical treatment in respect to length of stay, reduction in PICU admission rates or intubation frequency. The early use of non-invasive respiratory support devices in less intensive scenarios to facilitate earlier respiratory support may have an impact on outcome by avoiding progression of the disease process. High Flow Nasal Cannula (HFNC) therapy has emerged as a new method to provide humidified air flow to deliver a non-invasive form of positive pressure support with titratable oxygen fraction. There is a lack of high-grade evidence on use of HFNC therapy in bronchiolitis. METHODS/DESIGN: Prospective multi-centre randomised trial comparing standard treatment (standard subnasal oxygen) and High Flow Nasal Cannula therapy in infants with bronchiolitis admitted to 17 hospitals emergency departments and wards in Australia and New Zealand, including 12 non-tertiary regional/metropolitan and 5 tertiary centres. The primary outcome is treatment failure; defined as meeting three out of four pre-specified failure criteria requiring escalation of treatment or higher level of care; i) heart rate remains unchanged or increased compared to admission/enrolment observations, ii) respiratory rate remains unchanged or increased compared to admission/enrolment observations, iii) oxygen requirement in HFNC therapy arm exceeds FiO2 ≥ 40 % to maintain SpO2 ≥ 92 % (or ≥94 %) or oxygen requirement in standard subnasal oxygen therapy arm exceeds >2L/min to maintain SpO2 ≥ 92 % (or ≥94 %), and iv) hospital internal Early Warning Tool calls for medical review and escalation of care. Secondary outcomes include transfer to tertiary institution, admission to intensive care, length of stay, length of oxygen treatment, need for non-invasive/invasive ventilation, intubation, adverse events, and cost. DISCUSSION: This large multicenter randomised trial will allow the definitive assessment of the efficacy of HFNC therapy as compared to standard subnasal oxygen in the treatment of bronchiolitis. TRIAL REGISTRATION: The trial is registered with the Australian and New Zealand Clinical Trials Registry ACTRN12613000388718 (registered on 10 April 2013).

OBJECTIVE: To evaluate the effect of the State of Origin rugby league series on the number of emergency department (ED) presentations in Queensland. DESIGN AND SETTING: Retrospective analysis of Emergency Department Information System data from 25 Queensland EDs for game 10s and matched control 10s during the annual State of Origin series from 2005 to 2012. The Queensland team won seven of the eight series in this period. MAIN OUTCOME MEASURES: Number of patients presenting to Queensland EDs on 24 game 10s and 80 control 10s. RESULTS: Proportionally, a binomial test indicated there were significantly fewer ED presentations on game 10s (49,702) than on control 10s (172,351) (P<0.001). On average, there were 2,154 presentations per 10 on control 10s and 2,071 on game 10s, representing a 4% reduction on game 10s. CONCLUSION: We found that the State of Origin series was associated with fewer ED presentations on game 10s. We believe these results have broader implications for workforce planning and resource allocation.

OBJECTIVE: Paediatric status epilepticus (SE) has potential for long-term sequelae. Existing data demonstrate delays to aspects of care. The objective of the present study was to examine the feasibility of collecting data on children with paediatric SE and describe current management strategies in pre-hospital and in-hospital settings. METHODS: A pilot, prospective, observational cohort study of children 4 weeks to 16 years of age with SE, in four EDs in Australia. Clinical details including medications administered, duration of seizure and short-term outcomes were collected. Follow up occurred by telephone at 1 month. RESULTS: We enrolled 167 children with SE. Mean age was 5.4 years (standard deviation [SD] 4.1), and 81 (49%) male. Median seizure duration was 10 min (interquartile range 7-30). Midazolam was the first medication administered in 87/100 (87%) instances, mean dose of 0.21 mg/kg (SD 0.13). The dose of midazolam was adequate in 30 (35%), high (>0.2 mg/kg) in 44 (51%) and low (<0.1 mg/kg) in 13 (15%). For second-line agents, levetiracetam was administered on 33/55 (60%) occasions, whereas phenytoin and phenobarbitone were administered on 11/55 (20%) occasions each. Mean dose of levetiracetam was 26.4 mg/kg (SD 13.5). One hundred and four (62%) patients were admitted to hospital, with 13 (8%) admitted to ICU and seven (4%) intubated. CONCLUSION: In children presenting with SE in Australia medical management differed from previous reports, with midazolam as the preferred benzodiazepine, and levetiracetam replacing phenytoin as the preferred second-line agent. This pilot study indicates the feasibility of a paediatric SE registry and its utility to understand and optimise practice.

OBJECTIVE: The aim of the present study was to describe the epidemiology and clinical features of patients presenting to the ED with suspected and confirmed COVID-19. METHODS: The COVID-19 ED (COVED) Project is an ongoing prospective cohort study in Australian EDs. This analysis presents data from eight sites across Victoria and Tasmania for July 2020 (during Australia's 'second wave'). All adult patients who met criteria for 'suspected COVID-19' and underwent testing for SARS-CoV-2 in the ED were eligible for inclusion. Study outcomes included a positive SARS-CoV-2 test result and mechanical ventilation. RESULTS: In the period 1 July to 31 July 2020, there were 30 378 presentations to the participating EDs and 2917 (9.6%; 95% confidence interval 9.3-9.9) underwent testing for SARS-CoV-2. Of these, 50 (2%) patients returned a positive result. Among positive cases, two (4%) received mechanical ventilation during their hospital admission compared to 45 (2%) of the SARS-CoV-2 negative patients (odds ratio 1.7, 95% confidence interval 0.4-7.3; P = 0.47). Two (4%) SARS-CoV-2 positive patients died in hospital compared to 46 (2%) of the SARS-CoV-2 negative patients (odds ratio 1.7, 95% confidence interval 0.4-7.1; P = 0.49). Strong clinical predictors of a positive SARS-CoV-2 result included self-reported fever, non-smoking status, bilateral infiltrates on chest X-ray and absence of a leucocytosis on first ED blood tests (P < 0.05). CONCLUSION: In this prospective multi-site study from July 2020, a substantial proportion of ED patients required SARS-CoV-2 testing, isolation and enhanced infection prevention and control precautions. Presence of SARS-CoV-2 on nasopharyngeal swab was not associated with death or mechanical ventilation.

OBJECTIVE: The aim of the present study was to describe the characteristics and outcomes of patients presenting to Australian EDs with suspected and confirmed COVID-19 during 2020, and to determine the predictors of in-hospital death for SARS-CoV-2 positive patients. METHODS: This analysis from the COVED Project presents data from 12 sites across four Australian states for the period from 1 April to 30 November 2020. All adult patients who met local criteria for suspected COVID-19 and underwent testing for SARS-CoV-2 in the ED were eligible for inclusion. Study outcomes were mechanical ventilation and in-hospital mortality. RESULTS: Among 24 405 eligible ED presentations over the whole study period, 423 tested positive for SARS-CoV-2. During the 'second wave' from 1 July to 30 September 2020, 26 (6%) of 406 SARS-CoV-2 patients received invasive mechanical ventilation, compared to 175 (2%) of the 9024 SARS-CoV-2 negative patients (odds ratio [OR] 3.5; 95% confidence interval [CI] 2.3-5.2, P < 0.001), and 41 (10%) SARS-CoV-2 positive patients died in hospital compared to 312 (3%) SARS-CoV-2 negative patients (OR 3.2; 95% CI 2.2-4.4, P = 0.001). For SARS-CoV-2 positive patients, the strongest independent predictors of hospital death were age (OR 1.1; 95% CI 1.1-1.1, P < 0.001), higher triage category (OR 3.5; 95% CI 1.3-9.4, P = 0.012), obesity (OR 4.2; 95% CI 1.2-14.3, P = 0.024) and receiving immunosuppressive treatment (OR 8.2; 95% CI 1.8-36.7, P = 0.006). CONCLUSIONS: ED patients who tested positive for SARS-CoV-2 had higher odds of mechanical ventilation and death in hospital. The strongest predictors of death were age, a higher triage category, obesity and receiving immunosuppressive treatment.

RESULTS: There were 106 136 presentations to the participating EDs and 12 055 (11.4%; 95% confidence interval [CI] 11.2-11.6) underwent testing for SARS-CoV-2. Of these, 255 (2%) patients returned a positive result. Among positive cases, 13 (5%) received mechanical ventilation during their hospital admission compared to 122 (2%) of the SARS-CoV-2 negative patients (odds ratio 2.7; 95% CI 1.5-4.9, P = 0.001). Nineteen (7%) SARS-CoV-2 positive patients died in hospital compared to 212 (3%) of the SARS-CoV-2 negative patients (odds ratio 2.3; 95% CI 1.4-3.7, P = 0.001). Strong clinical predictors of the SARS-CoV-2 test result included self-reported fever, sore throat, bilateral infiltrates on chest X-ray, and absence of a leucocytosis on first ED blood tests (P < 0.05). CONCLUSIONS: In this prospective multi-site study during Australia's 'second wave', a substantial proportion of ED presentations required SARS-CoV-2 testing and isolation. Presence of SARS-CoV-2 on nasopharyngeal swab was associated with an increase in the odds of death and mechanical ventilation in hospital.

OBJECTIVE: The Ottawa subarachnoid haemorrhage (SAH) rule suggests that alert patients older than 15 years with a severe nontraumatic headache reaching maximum intensity within 1 h and absence of high-risk variables effectively have a SAH ruled out. We aimed to determine the proportion of emergency department (ED) patients with any headache fulfilling the entry criteria for the Ottawa SAH rule. PATIENTS AND METHODS: The Ottawa SAH rule was applied retrospectively in a substudy of a prospective snapshot of 34 EDs in Queensland, Australia, carried out over 4 weeks in September 2014. Patient aged 18 years and older with a nontraumatic headache of any potential cause were included. Clinical data and results of investigations were collected. RESULTS: Data were available for 644 (76%) patients. A total of 149 (23.1%, 95% confidence interval: 20.0-26.5%) fulfilled and 495 (76.9%, 95% confidence interval: 73.5-80.0%) did not fulfil the entry criteria. In patients who fulfilled the entry criteria, 30 (<5% overall) did not have any high-risk variables for SAH. In patients who fulfilled the entry criteria and had at least 1 high-risk feature, almost half (46%) received a computed tomographic brain. No SAH were missed. CONCLUSION: In this descriptive observational study, the majority of ED patients presenting with a headache did not fulfil the entry criteria for the Ottawa SAH rule. Less than 5% of the patients in this cohort could have SAH excluded on the basis of the rule. More definitive studies are needed to determine an accepted benchmark for the proportion of patients receiving further work-up (computed tomographic brain) after fulfilling the entry criteria for the Ottawa SAH rule.

Emergency care needs to be underpinned by the highest quality evidence. However, research involving critically ill patients in the emergency setting has unique ethical, logistical and regulatory issues. Informed consent is a well-established principle in conventional research. In this article, we discuss informed consent as it pertains to the difficulties of research in the emergency setting. Alternatives to informed consent are discussed. Human research ethics committees require a greater understanding of consent issues in emergency care research for Australia to remain competitive internationally.

OBJECTIVES: The objective of this study was to describe demographic and clinical characteristics including features that were consistent with subarachnoid hemorrhage (SAH), use of diagnostic tests, emergency department (ED) discharge diagnoses, and disposition of adult patients presenting with an acute headache to EDs statewide across Queensland, Australia. In addition, potential variations in the presentation and diagnostic workup between principal-referral and city-regional hospitals were examined. METHODS: A prospective cross-sectional study was conducted over 4 weeks in September 2014. All patients ≥ 18 years presenting to one of 29 public and five private hospital EDs across the state with an acute headache were included. The headache had to be the principal presenting complaint and nontraumatic. The 34 study sites attend to about 90% of all ED presentations statewide. The treating doctor collected clinical information at the time of the ED visit including the characteristics of the headache and investigations performed. A study coordinator retrieved results of investigations, ED discharge diagnoses, and disposition from state databases. Variations in presentation, investigations, and diagnosis between city-regional and principal-referral hospitals were examined. RESULTS: There were 847 headache presentations. Median (range) age was 39 (18-92) years, 62% were female, and 31% arrived by ambulance. Headache peaked instantly in 18% and ≤ 1 hour in 44%. It was "worst ever" in 37%, 10/10 in severity in 23%, and associated with physical activity in 7.4%. Glasgow Coma Scale score was < 15 in 4.1%. Neck stiffness was noted on examination in 4.8%. Neurologic deficit persisting in the ED was found in 6.5%. A computed tomography (CT) head scan was performed in 38% (318/841, 95% CI = 35% to 41%) and an lumbar puncture in 4.7% (39/832, 95% CI = 3.4% to 6.3%). There were 18 SAH, six intraparenchymal hemorrhages, one subdural hematoma, one newly diagnosed brain metastasis, and two bacterial meningitis. Migraine was diagnosed in 23% and "primary headache not further specified" in 45%. CT head scans were more likely to be performed in principal-referral hospitals (41%) compared to city-regional hospitals (33%). The headache in patients presenting to the latter was less likely to be instantly peaking or associated with activity, but was no less severe in intensity and was more frequently accompanied by nausea and vomiting. Their diagnosis was more likely to be a benign primary headache. Variations in CT scanning could thus be due to differences in the case mix. The median (interquartile range) ED length of stay was 3.1 (2.2 to 4.5) hours. Patients was discharged from the ED or admitted to the ED short-stay unit prior to discharge in 57 and 23% of cases, respectively. CONCLUSIONS: The majority of patients had a benign diagnosis, with intracranial hemorrhage and bacterial meningitis accounting for only 3% of the diagnoses. There are variations in the proportion of patients receiving CT head scans between city-regional and principal-referral hospitals. As 38% of headache presentations overall underwent CT scanning, there is scope to rationalize diagnostic testing to rule out life-threatening conditions.

OBJECTIVE: To compare the efficacy of nebulized fentanyl (NF) with i.v. morphine (IVM) in paediatric patients presenting to the ED with clinically suspected limb fractures. METHODS: A convenience sample of patients aged 4-13 years, presenting with clinically suspected limb fractures, were randomized to receive either NF at 4 microg/kg or IVM at 0.1 mg/kg. Pain scores were assessed at 0, 15 and 30 min using the Wong and Baker faces pain scale (0-10). Vital signs and adverse effects were also recorded. RESULTS: Of the 77 patients enrolled in the study, data were available for analysis on 73 patients. Of those, 36 received NF and 37 received IVM. The two groups were similar in terms of demographics and initial pain scores. Mean pain score at 15 min was decreased by 3.06 (NF) and by 1.97 (IVM) (difference 1.09; 95% CI 2.32 to -0.32). At 30 min the decreases were 3.6 (NF) and 3.0 (IVM), respectively (difference 0.6; 95% CI 1.89 to -0.65). Decreases in pain scores for both NF and IVM were statistically significant (P < 0.0001), but the difference in the effect of NF and IVM did not reach statistical significance. There was no significant change in any vital signs or serious adverse events in either group. CONCLUSION: NF in a dose of 4 microg/kg given via a standard nebulizer provided clinically significant improvements in pain scores, comparable to IVM. NF should be considered as a treatment option for use in children presenting in acute pain.

OBJECTIVE: To determine whether slow or fast bandaid removal is less painful. DESIGN, SETTING AND PARTICIPANTS: A prospective, randomised, crossover trial was carried out at James Cook University, Townsville. Participants were healthy volunteers from Years 2 and 3 of the James Cook University medical school program. INTERVENTIONS: Medium-sized bandaids were applied bilaterally in three standard body locations and removed using slow and fast techniques. MAIN OUTCOME MEASURES: Pain scores were assessed using an 11-point verbal numeric pain scale. RESULTS: 65 participants were included in the study. The overall mean pain score for fast bandaid removal was 0.92 and for slow bandaid removal was 1.58. This represents a highly significant difference of 0.66 (P < 0.001). CONCLUSION: In young healthy volunteers, fast bandaid removal caused less pain than slow bandaid removal.

Hypertonic saline (HS) is being increasingly used for the management of a variety of conditions, most notably raised intracranial pressure. This article reviews the available evidence on HS solutions as they relate to emergency medicine, and develops a set of recommendations for its use. To conclude, HS is recommended as an alternative to mannitol for treating raised intracranial pressure in traumatic brain injury. HS is also recommended for treating severe and symptomatic hyponatremia, and is worth considering for both recalcitrant tricyclic antidepressant toxicity and for cerebral oedema complicating paediatric diabetic ketoacidosis.

We evaluated the effect of telemedicine compared with traditional telephone conversations when evaluating patients for aeromedical retrieval. A convenience sample of consecutive patients referred for retrieval from Palm Island over a six-month period was compared retrospectively with patients referred during the previous six months. There was a significant difference (P = 0.014) in the number of patients referred in the telemedicine period (113) compared to the previous six months (78), which may have been a seasonal fluctuation. There was a smaller proportion of aeromedical retrievals in the telemedicine period (78%) compared to the control period (92%), P = 0.009. Other significant differences between the telemedicine and control period included a larger proportion of patients not transferred at all (16% compared to 5%, P = 0.022) and a smaller percentage of rotary flights (52% compared with 73%, P = 0.004). Retrieval coordinators perceived that telemedicine use prevented 10 aeromedical flights and six night flights. The coordinators and referrers felt that telemedicine improved patient care in 75% and 65% of consultations, respectively. The coordinators felt that it improved communication with the referring doctor for 84% of the consultations.
