Assessing need for extracorporeal cardiopulmonary resuscitation for out-of-hospital cardiac arrest using Power BI for data visualisation.
To estimate the number of patients in refractory out-of-hospital cardiac arrest (OHCA) potentially suitable for transport to an extracorporeal cardiopulmonary resuscitation (ECPR)-capable hospital in Brisbane, Queensland, Australia, based on outcome predictors for ECPR, ambulance geolocation and patient data. ⋯ Retrospective data collected from existing ambulance databases can be used to model patient suitability for ECPR. Relatively few patients with refractory OHCA in Queensland, Australia, could be attended and transported to an ECPR-capable centre within clinically acceptable timeframes. Further studies of the transport logistics and economic implications of providing ECPR services for OHCA are required to better inform decisions around this intervention.

Development, implementation and evaluation of a process to recognise and reduce aggression and violence in an Australian emergency department.
In 2018, we developed and implemented a novel approach to recognition and response to occupational violence and aggression (OVA). It included routine use of the Brøset Violence Checklist for all ED patients integrated with a score-based notification and response framework. The present study evaluated the impact of the new process on staff knowledge, perceptions and confidence regarding OVA in ED and the rate of security events related to OVA. ⋯ A process including routine OVA risk assessment and a notification and response framework reduced unplanned security events due to OVA and increased staff confidence in recognition and management of OVA. This approach may be suitable for use more broadly in ED.

Ocular ultrasound (US) is not one of ACEMs 'big 5' in terms of US capability that is expected of a trainee or FACEM. Most texts have a small chapter dedicated to ocular US but it is usually at the back or a subsection of a chapter where it is rarely seen or appreciated. However, it is a straightforward scan to perform with many benefits which will be discussed in this article. ⋯ This has the added benefit of being able to share images with an ophthalmologist remotely, improving time to definitive treatment. It can also be used in patients who cannot cooperate with sitting at a slitlamp, for example moribund or trauma patients. The authors propose that ocular US teaching should be incorporated into the ACEM syllabus, being a vital adjunct to a comprehensive eye examination.

Effect of tourniquet time on whole blood point-of-care lactate concentration: A healthy human volunteer study.
Lactate is frequently utilised in clinical practice. Some have concerns that tourniquet application for venous blood collection may falsely elevate venous lactate. The objective of the present study was to determine the effect of tourniquet time on varying venous lactate concentrations. ⋯ In the present study tourniquet application for blood collection did not significantly increase lactate concentration. Hence, clinically a raised venous lactate concentration should not be attributed to prolonged tourniquet application.
