Multicenter Study
17 Exploring ambulance conveyances to the emergency department: a descriptive analysis of non-urgent transports.
An NHS England report highlighted key issues in how patients were initially navigating access to healthcare. This has manifested in increased pressure on ambulance services and emergency departments (EDs) to provide high quality, safe and efficient services to manage this demand. This study aims to identify non-urgent conveyances by ambulance services to the ED that would be suitable for care at scene or an alternative response. ⋯ 16% of ambulance conveyances to ED in 2014 were non-urgent with around 1 in 3 patients under the age of 34 conveyed with non-urgent complaints. 1 in 5 patients had a non-urgent conveyance out of hours. AMPDS analysis identified target areas for intervention including referrals from other healthcare providers. Final ED diagnosis identified specific patient target areas including minor illness and alcohol intoxication.emermed;34/12/A872-a/F2F2F2Figure 2emermed;34/12/A872-a/F3F3F3Figure 3Age of patients taken to ED by ambulance (avoidable).

Despite successful vaccination programmes meningococcal disease (MD) remains the leading infectious cause of septicaemia and death in children in the UK and Ireland.1,2 The early diagnosis of MD significantly improves outcomes with reduced morbidity and mortality.1,2 The early stages of MD are often indistinguishable from a simple viral illness making an early positive diagnosis of MD difficult.1 Hibergene have developed a commercially available bedside Loop-mediated isothermal AMPlification PCR (LAMP-MD) test that is a highly sensitive 0.89 (95%CI 0.72-0.96) and specific 1.0 (95%CI 0.97-1.0) for identifying children with invasive MD (4) (figure 1).emermed;34/12/A895-a/F1F1F1Figure 1 AIMS: The aims of this RCEM funded study were:Assess the ease of use and suitability for the EDDetermine the time taken to perform the testIndependently verify LAMP-MD performance against TaqMan quantitative PCR. ⋯ Meningitis Research Foundation.

A 'whole body' or 'pan-scan' computed tomography (CT) imaging approach is now becoming the standard of care during the early management of adult patients with suspected severe blunt multitrauma. A number of studies have variously reported a mortality benefit or no benefit from a pan-scan approach compared to that of carrying out body region-focused CT and/or plain radiographs or a mixture of imaging modalities. However, unanswered questions still remain due to the significant heterogeneity in practice between institutions, and the limitations of published studies. The potential risk for harm from ionising radiation or intravenous contrast-induced nephropathy is still a concern, especially where mortality benefit from an unselective pan-scan approach is yet to be definitively proven.We present the results of our latest analysis of the Trauma Audit and Research Network (TARN) database; updated to take into account the establishment of the regional trauma network system and focusing on the Major Trauma Centre's (MTC's). ⋯ The results of our investigation demonstrate that there is no risk adjusted mortality benefit observed from current practice in MTCs in England and Wales. Key issues remain to be addressed such as pan-scan selection criteria and the significant heterogeneity observed in practice across institutions.

Recent studies suggest that approximately one per thousand paediatric ED attendances may require some sort of critical procedure, with intubation being by far the most common. It is unknown how often critical non-airway procedures such as chest decompression, CPR, ED thoracotomy, defibrillation, pacing, and advanced vascular access techniques are performed by paediatric emergency clinicians. ⋯ More than half of the paediatric emergency clinicians surveyed had performed CPR and inserted an intraosseous needle within the last 12 months. Performance of other non-airway critical procedures was less common, and associated with less procedural confidence.

The benefit of antiplatelet medication in confirmed acute coronary syndrome (ACS) is well established. In the Emergency Department (ED) diagnostic uncertainty may lead to over-treatment, with consequent risks (e.g., bleeding), or under-treatment, compromising clinical outcomes. Clinicians must subjectively balance the anticipated risks and benefits with their perceived probability of ACS in order to decide whether to prescribe these medications. We aimed to construct a clinical model to optimise and personalise recommendations for anti-platelet prescription in this context. ⋯ Systematic review identified three relevant original studies, and three sub-studies. After extracting data, we constructed two separate models, based on clinical outcomes after 30 days and 12 months. Aspirin alone led to greater net utility at probabilities below 7.4%, whereas treatment with ticagrelor led to greater net benefit when the probability of ACS exceeded 8.3% (figures 1 and 2). Sensitivity analyses including 10,000-fold Monte Carlo simulations demonstrated that the models were robust to a wide range of assumptions (figure 3).emermed;34/12/A870-a/F1F1F1Figure 1Acute coronary syndrome risk thresholds of treatment strategy superiority.

This has potential to improve clinical outcomes when used alongside a prediction model, such as the Manchester Acute Coronary Syndromes (MACS) decision aid, which calculates each patient's individual probability of ACS. The clinical and cost effectiveness of this novel 'precision Emergency Medicine' approach should now be evaluated in clinical studies.
