The paper by Body et al is concerned with the evaluation of decision aids, which can be used to identify potential acute coronary syndromes (ACS) in the ED. The authors previously developed the Manchester Acute Coronary Syndromes model (MACS) decision aid, which uses several clinical variables and two biomarkers to 'rule in' and 'rule out' ACS. ⋯ Decision aids (as well as other types of 'diagnostic tests') are often evaluated in terms of diagnostic testing parameters such as the area under the receiver operating characteristic (ROC) curve, sensitivity and specificity. In this article, we explain how the ROC analysis is conducted and why it is an essential step towards developing a test with the desirable levels of sensitivity and specificity.

Children with mental health crises require access to specialised resources and services which are not yet standard in general and paediatric EDs. In 2010, we published a systematic review that provided some evidence to support the use of specialised care models to reduce hospitalisation, return ED visits and length of ED stay. We perform a systematic review to update the evidence base and inform current policy statements. ⋯ Lower-quality data suggest benefits to the use of specialised resources and services for paediatric mental health care in general and paediatric EDs. Experimental evaluation of strategies and the inclusion of patient-reported outcomes will improve confidence in these findings. Additional psychometric studies are needed for the HEADS-ED tool to be considered well established.

In order to enable fast treatment response to anaphylactic reactions, adrenaline auto-injectors (AAI) have been developed and manufactured. It has been reported in several studies that administration technique is suboptimal. The primary purpose of this study was to review the nature and extent of the deficiencies in administration technique among patients, parents/caregivers and healthcare professionals. ⋯ There was wide variation in administration techniques reported. However, studies designed using before-and-after training show that even a brief demonstration and educational intervention can improve technique. Further studies are required to design and pilot acceptable and cost-effective educational materials.

A short cut review was carried out to see if the presence of 'B lines' detected on lung ultrasound could be used to guide the volume of fluid replacement necessary in the resuscitation of the patient with sepsis. Four papers with some degree of relevance were found in the literature search. The author, date and country of publication, patient group studied, study type, relevant outcomes, results study weaknesses of these papers are tabulated. Although a promising concept, the remains a paucity of good quality evidence sufficient to recommend this approach.

A short cut review was carried out to see if 'finger' thoracostomy is a safe and effective method of treating a tension pneumothorax in a pre-hospital setting. Five relevant papers were found looking at this technique in the pre-hospital setting. The author, date and country of publication, patient group studied, study type, relevant outcomes, results study weaknesses of these papers are tabulated. This technique appears to be safe and effective when performed by trained physicians in a pre-hospital setting.
