Low-dose methoxyflurane is an inhaled non-opioid analgesic with a rapid onset of pain relief that is approved for emergency relief of moderate-to-severe trauma-related pain in adults. This analysis was performed to compare the efficacy and safety of low-dose methoxyflurane with standard of care analgesics in adults with trauma-related pain.Methods: A meta-analysis was performed on pooled data from randomized controlled trials identified via a systematic review. The primary endpoint was the pain intensity difference between baseline and various time intervals (5, 10, 15, 20, and 30 minutes) after initiation of treatment.Results: The pain intensity difference was statistically superior with low-dose methoxyflurane compared with standard of care analgesics (overall estimated treatment effect=11.88, 95% CI=9.75– 14.00; P< 0.0001). The superiority of low-dose methoxyflurane was demonstrated at 5 minutes after treatment initiation and was maintained across all timepoints. Significantly more patients treated with methoxyflurane achieved response criteria of pain intensity ≤ 30 mm on a visual analog scale, and relative reductions in pain intensity of ≥ 30% and ≥ 50%, compared with patients who received standard of care analgesics. The median time to pain relief was shorter with methoxyflurane than with standard of care analgesics. The findings were consistent in a subgroup of elderly patients (aged ≥ 65 years).Conclusion: Methoxyflurane can be considered as an alternative to standard of care analgesics in pre-hospital and hospital settings for treatment of adult patients with acute trauma-related pain.Keywords: acute pain, inhaled analgesic, emergency service, wounds and injury, pain management, analgesia

Trauma pain management presents challenges in the pre-hospital setting, particularly in adverse or hostile environments as well as in busy emergency departments (EDs). Inhaled methoxyflurane, administered at analgesic doses via a disposable inhaler, has recently become available in Europe for the emergency treatment of moderate to severe pain in conscious adult trauma patients. A growing body of evidence demonstrates that inhaled methoxyflurane is well tolerated and effective in providing a rapid onset of analgesia. In this paper, we discuss the rationale for methoxyflurane use in trauma pain management, data from clinical trials recently conducted in Europe, its efficacy and safety profile compared to current standard treatments, its place in therapy and organizational impact. We conclude that inhaled methoxyflurane represents an effective treatment option in the different settings where trauma patients require rapid and flexible pain resolution, with potential organizational advantages.Keywords: emergency, pre-hospital, analgesia, non-opioid pain management

Stuart Hartshorn,1 Patrick Dissmann,2 Frank Coffey,3 Mark Lomax4 1Emergency Department, Birmingham Children’s Hospital, Birmingham, UK; 2Academic Department of Emergency Medicine, James Cook University Hospital, Middlesbrough, UK; 3DREEAM: Department of Research and Education in Emergency Medicine, Acute Medicine and Major Trauma, Nottingham University Hospitals NHS Trust, Nottingham, UK; 4Data Management & Statistics, Mundipharma Research Limited, Cambridge, UK Introduction: The undertreatment of acute pain presents a significant challenge in the Emergency Department. This post hoc subgroup analysis of a previously reported randomized controlled UK study reports the efficacy and safety of low-dose methoxyflurane analgesia in treating adolescent patients with moderate-to-severe trauma pain. Patients and methods: Three hundred patients (96 in the adolescent subgroup) aged ≥12 years requiring analgesia for acute trauma pain (pain score of 4–7 on the Numerical Rating Scale) at triage were randomized 1:1 to methoxyflurane (up to 6 mL) or placebo (normal saline), both administered using a Penthrox® inhaler. The patient could request rescue medication (paracetamol/opioids) at any time. The primary endpoint was the change from baseline in visual analog scale (VAS) pain intensity. Results: Mean VAS pain score for the adolescent subgroup at baseline was ~61 mm. Adjusted mean change in VAS pain intensity from baseline to 5, 10, 15, and 20 minutes was −24.5, –28.1, –31.6, and –31.7 mm for methoxyflurane and −14.6, –18.8, –19.2, and –23.7 mm for placebo, with a statistically significant treatment effect in favor of methoxyflurane overall across all four time points (–9.9 mm; 95% CI: −17.4, –2.4 mm; P=0.0104). Median time to first pain relief was significantly shorter with methoxyflurane (1 minute) than placebo (3 minutes, P

Abstract Background Large numbers of people are killed or severely injured following injuries each year and these injuries place a large burden on health care resources. The majority of the severely injured are not fully recovered 12-18 months later. Psychological disorders are common post injury and are associated with poorer functional and occupational outcomes. Much of this evidence comes from countries other than the UK, with differing health care and compensation systems. Early interventions can be effective in treating psychological morbidity, hence the scale and nature of the problem and its impact of functioning in the UK must be known before services can be designed to identify and manage psychological morbidity post injury. Methods/Design A longitudinal multi-centre study of 680 injured patients admitted to hospital in four areas across the UK: Nottingham, Leicester/Loughborough, Bristol and Surrey. A stratified sample of injuries will ensure a range of common and less common injuries will be included. Participants will complete a baseline questionnaire about their injury and pre-injury quality of life, and follow-up questionnaires 1, 2, 4, and 12 months post injury. Measures will include health and social care utilisation, perceptions of recovery, physical, psychological, social and occupational functioning and health-related quality of life. A nested qualitative study will explore the experiences of a sample of participants, their carers and service providers to inform service design. Discussion This study will quantify physical, psychological, social and occupational functioning and health and social care utilisation following a range of different types of injury and will assess the impact of psychological disorders on function and health service use. The findings will be used to guide the development of interventions to maximise recovery post injury.

Abstract Background Regular cycling has been shown to improve health and has a role in tackling the threats posed by obesity and inactivity. Cycle collisions, particularly those involving motorised vehicles, can lead to significant mortality and morbidity and are currently a barrier to wider uptake of cycling. There is evidence that the conspicuity of cyclists is a factor in many injury collisions. Low-cost, easy to use retro-reflective and fluorescent clothing and accessories ('conspicuity aids') are available. Their effectiveness in reducing cycling collisions is unknown. The study is designed to investigate the relationship between the use of conspicuity aids and risk of collision or evasion crashes for utility and commuter cyclists in the UK. Methods/Design A matched case-control study is proposed. Cases are adult commuter and utility cyclists involved in a crash resulting from a collision or attempted evasion of a collision with another road user recruited at a UK emergency department. Controls are commuter and utility cyclists matched by journey purpose, time and day of travel and geographical area recruited at public and private cycle parking sites. Data on the use of conspicuity aids, crash circumstances, demographics, cycling experience, safety equipment use, journey characteristics and route will be collected using self-completed questionnaires and maps. Conditional logistic regression will be used to calculate adjusted odds ratios and 95% confidence intervals of the risk of a crash when using any item of fluorescent or reflective clothing or equipment. Discussion This study will provide information on the effectiveness of conspicuity aids in reducing the risk of injury to cyclists resulting from crashes involving other road users.

Abstract Background Globally and nationally large numbers of people are injured each year, yet there is little information on the impact of these injuries on people's lives, on society and on health and social care services. Measurement of the burden of injuries is needed at a global, national and regional level to be able to inform injured people of the likely duration of impairment; to guide policy makers in investing in preventative measures; to facilitate the evaluation and cost effectiveness of interventions and to contribute to international efforts to more accurately assess the global burden of injuries. Methods/Design A prospective, longitudinal multi-centre study of 1333 injured individuals, atttending Emergency Departments or admitted to hospital in four UK areas: Swansea, Surrey, Bristol and Nottingham. Specified quotas of patients with defined injuries covering the whole spectrum will be recruited. Participants (or a proxy) will complete a baseline questionnaire regarding their injury and pre-injury quality of life. Follow up occurs at 1, 4, and 12 months post injury or until return to normal function within 12 months, with measures of health service utilisation, impairment, disability, and health related quality of life. National estimates of the burden of injuries will be calculated by extrapolation from the sample population to national and regional computerised hospital in-patient, emergency department and mortality data. Discussion This study will provide more detailed data on the national burden of injuries than has previously been available in any country and will contribute to international collaborative efforts to more accurately assess the global burden of injuries. The results will be used to advise policy makers on prioritisation of preventive measures, support the evaluation of interventions, and provide guidance on the likely impact and degree of impairment and disability following specific injuries.

Background: Providing feedback is a key aspect of simulated participants' (SPs) educational work. In teaching contexts, the ability to provide feedback to learners is central to their role. Suboptimal feedback practices may deny learners the valuable feedback they need to learn and improve. This scoping review systematically maps the evidence related to SPs' role as educators and identifies how SPs prepare for their role and feedback practices., Methods: The authors conducted a scoping review and included a group of international stakeholders with experience and expertise in SP methodology. Five online databases were systematically searched and ERIC, MedEdPortal and MedEdPublish were hand searched to identify relevant studies. Inclusion/exclusion criteria were developed. Data screening and subsequently data charting were performed in pairs. The results of data charting were thematically analysed including categories relating to the Association of SP Educators (ASPE) Standards of Best Practice (SOBP)., Results: From 8179 articles identified for the title and abstract screening, 98 studies were included. Studies reported the benefit of SPs' authentic role portrayal and feedback interactions for learners and on the reported learning outcomes. Data was heterogeneous with a notable lack of consistency in the detail regarding the scenario formats for communication skills training interventions, SP characteristics, and approaches to training for feedback and role portrayal., Conclusions: The published literature has considerable heterogeneity in reporting how SPs are prepared for role portrayal and feedback interactions. Additionally, our work has identified gaps in the implementation of the ASPE SOBP, which promotes effective SP-learner feedback interactions. Further research is required to identify effective applications of SP methodology to prepare SPs for their role as educators.

Background: Postgraduate General Practice (GP) training is structured around a formal curriculum set out by the training body. It also includes a "hidden curriculum" of experiential workplace learning in a heterogenous learning environment [1]. There is no formal national annual survey of GP trainees and their views in Ireland., Methods: The research aim was to evaluate what the trainee population think of their training environment, and to analyse the contributory factors. A mixed methods cross-sectional survey was distributed to all third- and fourth-year GP trainees (N = 404). The Manchester Clinical Placement Index was adapted for the study., Results: The response rate was 30.94% (N = 125). Questions 1 to 7 provided a description of the characteristics of the study population. The remainder of the questions focused on aspects which relate to constituents of the learning environment. The responses were broadly and convincingly positive and supportive of the good work being done in GP training and by trainers in Ireland today across both qualitative and quantitative findings. One notable exception was in the area of feedback where single handed fourth year practices were found to be underperforming., Conclusions: The current research findings were broadly positive and supportive of the good work being done in GP training and by trainers in Ireland today. Further research will be needed to validate the study instrument and to further refine some aspects of its configuration. The implementation of such a survey on a regular basis may have merit as part of the quality assurance process in GP education alongside existing feedback structures [2]., (© 2023.

Excessive alcohol consumption carries a significant health, social and economic burden. Screening, brief intervention and referral to treatment (SBIRT) is one approach to identifying patients with excessive alcohol consumption and providing interventions to help them reduce their drinking. However, healthcare workers in urgent and emergency care settings do not routinely integrate SBIRT into clinical practice and raise a lack of training as a barrier to SBIRT delivery. Therefore, "Alcohol Prevention in Urgent and Emergency Care" (APUEC) training was developed, delivered, and evaluated. APUEC is a brief, stand-alone, multimedia, interactive digital training package for healthcare workers. The aim of APUEC is to increase positive attitudes, knowledge, confidence and skills related to SBIRT through the provision of (a) education on the impact of alcohol and the role of urgent and emergency care in alcohol prevention, and (b) practical guidance on patient assessment, delivery of brief advice and making referral decisions. Development involved collaborative-participatory design approaches and a rigorous six-step ASPIRE methodology (involving n = 28 contributors). APUEC was delivered to healthcare workers who completed an online survey ( n = 18) and then participated in individual qualitative interviews ( n = 15). Analysis of data was aligned with Levels 1-3 of the Kirkpatrick Model of Training Evaluation. Survey data showed that all participants (100%) found the training useful and would recommend it to others. Insights from the qualitative data showed that APUEC digital training increases healthcare workers' perceived knowledge, confidence and skills related to alcohol prevention in urgent and emergency care settings. Participants viewed APUEC to be engaging and relevant to urgent and emergency care workers. This digital training was perceived to be useful for workforce skills development and supporting the implementation of SBIRT in clinical practice. While the impact of APUEC on clinician behaviour and patient outcomes is yet to be tested, APUEC digital training could easily be embedded within education and continuing professional development programmes for healthcare workers and healthcare trainees of any discipline. Ultimately, this may facilitate the integration of SBIRT into routine care and contribute to population health improvement.

Background: The aim of the study was to ascertain the views and experiences of those working in urgent and emergency care (UEC) settings towards screening, brief intervention, and referral to treatment (SBIRT) for alcohol, to inform future practice., Objectives: To explore i) views towards health promotion, ii) views towards and practice of SBIRT, iii) facilitators and barriers to delivering SBIRT, iv) training needs to support future SBIRT practice, and v) comparisons in views and attitudes between demographic characteristics, geographical regions, setting and occupational groups., Methods: This was an open cross-sectional international survey, using an online self-administered questionnaire with closed and open-ended responses. Participants were ≥18 years of age, from any occupational group, working in urgent and emergency care (UEC) settings in any country or region., Results: There were 362 respondents (aged 21-65 years, 87.8% shift workers) from 7 occupational groups including physicians (48.6%), nurses (22.4%) and advanced clinical practitioners (18.5%). Most believed that health promotion is part of their role, and that SBIRT for alcohol prevention is needed and appropriate in UEC settings. SBIRT was seen to be acceptable to patients. 66% currently provide brief alcohol advice, but fewer screen for alcohol problems or make alcohol-related referrals. The most common barriers were high workload and lack of funding for prevention, lack of knowledge and training on SBIRT, lack of access to high-quality resources, lack of timely referral pathways, and concerns about patient resistance to advice. Some views and attitudes varied according to demographic characteristics, occupation, setting or region., Conclusions: UEC workers are willing to engage in SBIRT for alcohol prevention but there are challenges to implementation in UEC environments and concerns about workload impacts on already-burdened staff, particularly in the context of global workforce shortages. UEC workers advocate for clear guidelines and policies, increased staff capacity and/or dedicated health promotion teams onsite, SBIRT education/training/resources, appropriate physical spaces for SBIRT conversations and improved alcohol referral pathways to better funded services. Implementation of SBIRT could contribute to improving population health and reducing service demand, but it requires significant and sustained commitment of time and resources for prevention across healthcare organisations., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Blake et al.

Background: Urgent and emergency care (UEC) settings provide an opportunity to prevent ill-health and promote healthy lifestyles with potential to screen and deliver interventions to under-served, at-risk populations. The aim of this study was to synthesise and summarise the evidence on the effectiveness and implementation of interventions for health promotion in UEC settings., Methods: PubMed and Embase (OVID) databases were used to search for studies published in English between January 2010 and January 2023. Systematic reviews and meta-analyses of studies that examined the effectiveness or implementation of face-to-face health promotion interventions for lifestyle behaviours delivered in UEC settings were eligible. Extracted data were synthesised and qualitatively summarised by lifestyle behaviour. Reviews were quality assessed using AMSTAR 2., Results: Eighteen reviews met the inclusion criteria; all included studies were conducted in emergency departments or trauma units. We identified 15 reviews on alcohol interventions (13 on effectiveness; 2 on implementation) and 3 on smoking interventions (effectiveness). There were no reviews of intervention studies targeting physical activity or diet and nutrition. There was heterogeneity across studies for study design, target populations, intervention design and content, comparator/control groups and outcomes assessed. The effectiveness of alcohol and smoking interventions in UEC settings varied but some reviews provided evidence of a significant decrease in alcohol consumption, alcohol-related outcomes and smoking in intervention groups, particularly in the short-term and in specific population groups. Research has focused on 'brief' interventions as part of screening, brief intervention and referral to treatment (SBIRT) approaches. Interventions are delivered by a wide range of staff with substantial variation in design. Alcohol brief interventions appear to be acceptable to UEC patients but clinicians face barriers in delivering them., Conclusions: UEC settings have been under-researched and appear to be under-utilised for delivering health promotion activities, except for alcohol prevention. Review level evidence suggests alcohol and smoking interventions are warranted in some population groups. However, further research is needed to determine the optimal intervention design, content and delivery mode for lifestyle behaviours which are suitable for implementation in UEC settings and promote long-term intervention effectiveness. Changes in clinical practice may be needed, including increased training, integration into service delivery and supportive policy, to facilitate the implementation of SBIRT for lifestyle behaviours. Interventions may need to be delivered in the wider UEC system such as urgent care centres, minor injury units and walk-in centres, in addition to emergency departments and trauma units, to support and increase health promotion activities in UEC settings., (© 2023.

Background: Younger and older adults attending the Emergency Department (ED) are a heterogeneous population. Longer length of ED stay is associated with adverse outcomes and may vary by age., Aims: To evaluate the associations between age and (1) clinical characteristics and (2) length of ED stay among adults attending ED., Methods: The NOttingham Cohort study in the Emergency Department (NOCED)-a retrospective cohort study-comprises new consecutive ED attendances by adults ≥ 18 years, at a secondary/tertiary care hospital, in 2019. Length of ED stay was dichotomised as < 4 and ≥ 4 h. The associations between age and length of ED stay were analysed by binary logistic regression and adjusted for socio-demographic and clinical factors including triage acuity., Results: 146,636 attendances were analysed; 75,636 (51.6%) resulted in a length of ED stay ≥ 4 h. Attendances of adults aged 65 to 74 years, 75 to 84 years and ≥ 85 years, respectively, had an increased risk (odds ratio (95% confidence interval) of length of ED stay ≥ 4 h of 1.52 (1.45-1.58), 1.65 (1.58-1.72), and 1.84 (1.75-1.93), compared to those of adults 18 to 64 years (all p < 0.001). These findings remained consistent in the subsets of attendances leading to hospital admission and those leading to discharge from ED., Discussion and Conclusion: In this real-world cohort study, older adults were more likely to have a length of ED stay ≥ 4 h, with the oldest old having the highest risk. ED target times should take into account age of attendees., (© 2022. The Author(s), under exclusive licence to Springer Nature Switzerland AG.)

Background: Ankle sprains are one of the most common musculoskeletal injuries, accounting for up to 5% of all Emergency Department visits in the United Kingdom. Ankle injury may be associated with future ankle osteoarthritis. Up to 70% of ankle osteoarthritis cases may be associated with previous ankle injury. There is limited research regarding the association between ankle sprain and ankle osteoarthritis development. The current study aims to phenotype those who suffer significant ankle ligament injuries, identify potential risk factors for ankle injuries and subsequent poor recovery, examine why individuals may develop osteoarthritis, and what factors influence this chance., Methods: In this multicentre cohort study participants were recruited from nine Emergency Departments and two Urgent Care Centres in the United Kingdom. Participants (aged 18-70 years old) were defined as those who had suffered an isolated acute ankle sprain, which was Ottawa Ankle Rules positive, but negative for a significant ankle fracture on x-ray. Age and sex matched controls were also recruited. The controls were individuals who had not suffered a significant ankle injury, including ankle pain, function affected for more than 7 days, or the ankle caused them to report to an Emergency Department. Data is collected through a series of seven questionnaires (at baseline, 3 months, 1 year, 3 years, 5 years, 10 years, and 15 years later). The questionnaires include four sections (demographic questions; index injury, and injury history questions; functional assessment questions; and quality of life questions) and are designed to collect detailed information about the individual, their injury, potential risk factors for ankle sprains and ankle osteoarthritis, plus their medical history and any medication consumed., Discussion: The Significant Ankle Ligament Injury (SALI) study aims to add to the limited knowledge regarding which factors can predict ankle sprains, complaints, and osteoarthritis. This is important because despite ankle sprains being regarded as a benign injury that resolves quickly, residual symptoms are not uncommon months and years after the injury.

This study concerns glulisine, a rapid-acting insulin analogue that plays a fundamental role in diabetes management. We have applied a combination of methods namely X-ray crystallography, and biophysical characterisation to provide a detailed insight into the structure and function of glulisine. X-ray data provided structural information to a resolution of 1.26 Å. Crystals belonged to the H3 space group with hexagonal (centred trigonal) cell dimensions a = b = 82.44 and c = 33.65 Å with two molecules in the asymmetric unit. A unique position of D21Glu, not present in other fast-acting analogues, pointing inwards rather than to the outside surface was observed. This reduces interactions with neighbouring molecules thereby increasing preference of the dimer form. Sedimentation velocity/equilibrium studies revealed a trinary system of dimers and hexamers/dihexamers in dynamic equilibrium. This new information may lead to better understanding of the pharmacokinetic and pharmacodynamic behaviour of glulisine which might aid in improving formulation regarding its fast-acting role and reducing side effects of this drug.

Background: We aimed to estimate the diagnostic accuracy of the VitalScan magnetocardiograph (MCG) for suspected acute coronary syndrome (ACS)., Methods: We undertook a prospective cohort study evaluating the diagnostic accuracy of the MCG in adults with suspected ACS. The reference standard of ACS was determined by an independent adjudication committee based on 30-day investigations and events. The cohort was split into a training sample, to derive the MCG algorithm and an algorithm combining MCG with a modified Manchester Acute Coronary Syndrome (MACS) clinical probability score, and a validation sample, to estimate diagnostic accuracy., Results: We recruited 756 participants and analysed data from 680 (293 training, 387 validation), of whom 96 (14%) had ACS. In the training sample, the respective area under the receiver operating characteristic (AUROC) curves were the following: MCG 0.66 (95% CI 0.58 to 0.74), MACS 0.64 (95% CI 0.54 to 0.73) and MCG+MACS 0.70 (95% CI 0.63 to 0.77). MCG specificity was 0.16 (95% CI 0.12 to 0.21) at the threshold achieving acceptable sensitivity for rule-out (>0.98). In the validation sample (n=387), the respective AUROCs were the following: MCG 0.56 (95% CI 0.48 to 0.64), MACS 0.69 (95% CI 0.61 to 0.77) and MCG+MACS 0.64 (95% CI 0.56 to 0.72). MCG sensitivity was 0.89 (95% CI 0.77 to 0.95) and specificity 0.15 (95% CI 0.12 to 0.20) at the rule-out threshold. MCG+MACS sensitivity was 0.85 (95% CI 0.73 to 0.92) and specificity 0.30 (95% CI 0.25 to 0.35)., Conclusion: The VitalScan MCG is currently unable to accurately rule out ACS and is not yet ready for use in clinical practice. Further developmental research is required., Competing Interests: Competing interests: The University of Sheffield received funding from Creavo Medical Technologies for the time committed to the study by its employees (SG, SJW)., (© Author(s) (or their employer(s)) 2021.

Pain management is a vital component of patient care, particularly in the emergency setting. Pain can hinder the opportunities to treat and manage pain-causing conditions and remains one of the primary reasons patients seek emergency medical care, yet despite this, pain often remains under-acknowledged, under-assessed and undertreated. Despite the importance of effective management of acute pain, there are currently no well-defined emergency medicine guidelines at a European level to support healthcare professionals in achieving this goal. The European Society for Emergency Medicine (EUSEM) identified this as a significant unmet requirement, for improving day-to-day patient management and for providing guidance to trainees and non-emergency medicine physicians. Under the auspices of EUSEM, a programme-the European Pain Initiative-was launched with the aim of providing information, advice and guidance on pain management in pre-hospital and emergency department settings. Search terms were developed to search MEDLINE, Cochrane database, Google Scholar and EMBASE online databases to return English language articles published in the last 10 years. A working package of reference materials was evaluated against inclusion and exclusion criteria and levels of evidence ascribed. A short survey was developed by the European Pain Initiative Steering Committee for completion by EUSEM members to evaluate actual clinical practice. A working document of > 800 publications was identified for further review and evaluation against agreed criteria. Some further publications were included by the Steering Committee to explore older literature for long-established analgesics, or newly emergent literature that was considered important for inclusion but was identified as the guideline development was underway. This article provides the methodology used to inform the guidelines, including survey results of EUSEM members on assessment and treatment of acute pain. A companion manuscript in this issue presents an evidence-based review and recommendations for individualised evaluation of acute pain in patients in emergency settings.

Background: In Europe, healthcare systems and education, as well as the clinical care and health outcomes of patients, varies across countries. Likewise, the management of acute events for patients also differs, dependent on the emergency care setting, e.g. pre-hospital or emergency department. There are various barriers to adequate pain management and factors common to both settings including lack of knowledge and training, reluctance to give opioids, and concerns about drug-seeking behaviour or abuse. There is no single current standard of care for the treatment of pain in an emergency, with management based on severity of pain, injury and local protocols. Changing practices, attitudes and behaviour can be difficult, and improvements and interventions should be developed with barriers to pain management and the needs of the individual emergency setting in mind., Methods: With these principles at the forefront, The European Society for Emergency Medicine (EUSEM) launched a programme-the European Pain Initiative (EPI)-with the aim of providing information, advice, and guidance on acute pain management in emergency settings., Results and Conclusions: This article provides treatment recommendations from recently developed guidelines, based on a review of the literature, current practice across Europe and the clinical expertise of the EPI advisors. The recommendations have been developed, evaluated, and refined for both adults and children (aged ≥ 1 year, ≤ 15 years), with the assumption of timely pain assessment and reassessment and the possibility to implement analgesia. To provide flexibility for use across Europe, options are provided for selection of appropriate pharmacological treatment.

Background: Patients with palpitations and pre-syncope commonly present to Emergency Departments (EDs) but underlying rhythm diagnosis is often not possible during the initial presentation. This trial compares the symptomatic rhythm detection rate of a smartphone-based event recorder (AliveCor) alongside standard care versus standard care alone, for participants presenting to the ED with palpitations and pre-syncope with no obvious cause evident at initial consultation., Methods: Multi-centre open label, randomised controlled trial. Participants ≥ 16 years old presenting to 10 UK hospital EDs were included. Participants were randomised to either (a) intervention group; standard care plus the use of a smartphone-based event recorder or (b) control group; standard care alone. Primary endpoint was symptomatic rhythm detection rate at 90 days. Trial registration number NCT02783898 (ClinicalTrials.gov)., Findings: Two hundred forty-three participants were recruited over an 18-month period. A symptomatic rhythm was detected at 90 days in 69 (n = 124; 55.6%; 95% CI 46.9-64.4%) participants in the intervention group versus 11 (n = 116; 9.5%; 95% CI 4.2-14.8) in the control group (RR 5.9, 95% CI 3.3-10.5; p < 0.0001). Mean time to symptomatic rhythm detection in the intervention group was 9.5 days (SD 16.1, range 0-83) versus 42.9 days (SD 16.0, range 12-66; p < 0.0001) in the control group. The commonest symptomatic rhythms detected were sinus rhythm, sinus tachycardia and ectopic beats. A symptomatic cardiac arrhythmia was detected at 90 days in 11 (n = 124; 8.9%; 95% CI 3.9-13.9%) participants in the intervention group versus 1 (n = 116; 0.9%; 95% CI 0.0-2.5%) in the control group (RR 10.3, 95% CI 1.3-78.5; p = 0.006)., Interpretation: Use of a smartphone-based event recorder increased the number of patients in whom an ECG was captured during symptoms over five-fold to more than 55% at 90 days. This safe, non-invasive and easy to use device should be considered part of on-going care to all patients presenting acutely with unexplained palpitations or pre-syncope., Funding: This study was funded by research awards from Chest, Heart and Stroke Scotland (CHSS) and British Heart Foundation (BHF) which included funding for purchasing the devices. MR was supported by an NHS Research Scotland Career Researcher Clinician award.
