Multicenter Study
Validation of the PredAHT-2 prediction tool for abusive head trauma.
The validated Predicting Abusive Head Trauma (PredAHT) clinical prediction tool calculates the probability of abusive head trauma (AHT) in children <3 years of age who have sustained intracranial injuries (ICIs) identified on neuroimaging, based on combinations of six clinical features: head/neck bruising, seizures, apnoea, rib fracture, long bone fracture and retinal haemorrhages. PredAHT version 2 enables a probability calculation when information regarding any of the six features is absent. We aimed to externally validate PredAHT-2 in an Australian/New Zealand population. ⋯ PredAHT-2 demonstrated reasonably high point sensitivity and specificity when externally validated in an Australian/New Zealand population. Performance was similar to that in the original validation study.

Multicenter Study Observational Study
Association of clinically important traumatic brain injury and Glasgow Coma Scale scores in children with head injury.
Head injury (HI) is a common presentation to emergency departments (EDs). The risk of clinically important traumatic brain injury (ciTBI) is low. We describe the relationship between Glasgow Coma Scale (GCS) scores at presentation and risk of ciTBI. ⋯ Outside clinical decision rules, decreasing levels of GCS are an important indicator for increasing risk of ciTBI, neurosurgery and death. The level of GCS should drive clinician decision-making in terms of urgency of neurosurgical consultation and possible transfer to a higher level of care.

Multicenter Study
Key occupational stressors in the ED: an international comparison.
The ED Stressor Scale outlines 15 stressors that are of importance for ED staff. Limited research has identified how commonly such stressors occur, or whether such factors are perceived with similar importance across different hospitals. This study sought to examine the frequency or perceived severity of these 15 stressors using a multicentre cohort of emergency clinicians (nurses and physicians) in EDs in two countries (Australia and Sweden). ⋯ Workload, inability to provide optimal care, workplace violence and death or sexual abuse of a child were consistently reported as the most distressing events across sites. The frequency with which these occurred differed in Australia and Sweden, likely due to differences in the healthcare systems.

Multicenter Study
Blood glucose reduction in patients treated with insulin and dextrose for hyperkalaemia.
Dextrose is commonly administered with insulin during the management of hyperkalaemia to avoid hypoglycaemia. Previous research has evaluated the incidence of hypoglycaemia; however, none have reported the extent of blood glucose reduction after this regimen. The aim of this study was to better characterise the changes in blood glucose and to identify patients who may have an increased response to insulin. ⋯ The extent of blood glucose reduction is variable and hypoglycaemia is common. The high incidence of hypoglycaemia highlights the importance of frequent blood glucose monitoring.

Multicenter Study Comparative Study
Comparison of four decision aids for the early diagnosis of acute coronary syndromes in the emergency department.
To directly compare the diagnostic accuracy of four decision aids (Troponin-only Manchester Acute Coronary Syndromes (T-MACS), History, ECG, Age, Risk factors and Troponin (HEART), Thrombolysis in Myocardial Infarction (TIMI) and Emergency Department Assessment of Chest Pain (EDACS)) used to expedite the early diagnosis of acute coronary syndromes (ACS) in the ED. ⋯ In this study, T-MACS could rule out AMI in 46.5% patients with 99.2% sensitivity. EDACS could rule out AMI in 48.3% patients with lower sensitivity, although the difference was not statistically significant. The HEART and TIMI scores had lower diagnostic accuracy.
