To determine whether admission delay (lead-time) and other factors are associated with hospital mortality rates of emergency medical patients. ⋯ MEWS, delta MEWS and sepsis were predictors of hospital mortality in emergency medical patients. Lead-time was not associated with mortality, which could be due to benefits of various treatments initiated in the ED. In patients requiring intensive care, however, the longer lead-time probably led to higher MEWS and mortality.

Apart from case reports and anecdotes, there are no published studies on the feasibility of using non-medical devices for emergency bystander cricothyroidotomy. This study evaluated the ability of non-trained junior doctors and medical students to place an emergency cricothyroidotomy on an embalmed cadaver using only a blade and a ballpoint pen. ⋯ In embalmed cadavers, inexperienced junior doctors and medical students with no prior training were able to place a successful cricothyroidotomy slightly more than half the time. It suggests that surgical cricothyroidotomy with a ballpoint pen and blade is a feasible option in extremis. It is unknown whether junior doctors from other specialties, such as emergency medicine, would perform better.

Review Meta Analysis
Heart-type fatty acid binding protein as an early marker for myocardial infarction: systematic review and meta-analysis.
Heart-type fatty acid binding protein (H-FABP) has been proposed as an early biomarker of myocardial infarction (MI). The authors aimed to undertake a systematic review and meta-analysis to estimate the early sensitivity and specificity of quantitative and qualitative H-FABP assays. ⋯ H-FABP has modest sensitivity and specificity for MI at presentation but estimates are subject to substantial uncertainty and primary data are subject to substantial heterogeneity. H-FABP may have a role alongside troponin in improving early sensitivity but comparison with high sensitivity troponin assays is required.

Randomized Controlled Trial
Can training improve laypersons helping behaviour in first aid? A randomised controlled deception trial.
There is limited evidence indicating that laypersons trained in first aid provide better help, but do not help more often than untrained laypersons. This study investigated the effect of conventional first aid training versus conventional training plus supplementary training aimed at decreasing barriers to helping. ⋯ Supplementary training on dealing with barriers to helping did not alter the helping behaviour. The timing and appropriateness of the aid provided can be improved.

Recent recommendations from the Society for Academic Emergency Medicine and the American College of Emergency Physicians identified the detection of delirium in the emergency department (ED) as a 'high yield' research objective. This review aimed to determine the occurrence rate, and physician detection rates, of delirium within the ED. A systematic literature review was conducted and identified using online databases. ⋯ Given the scale, addressing delirium should be a priority for clinicians and researchers. To improve delirium outcomes and hospital management, measures must include mechanisms to improve detection. Finding a single validated assessment method and facilitating research in this difficult patient population would be an important progress.
