RESUMO
Advances in left ventricular assist device (LVAD) therapy have resulted in increasing numbers of adult LVAD recipients in the community. However, device failure, stroke, bleeding, LVAD thrombosis and systemic infection can be life-threatening emergencies. Currently, four LVAD systems are implanted in six UK transplant centres, each of which provides device-specific information to local emergency services. This has resulted in inconsistent availability and content of information with the risks of delayed or inappropriate decision-making. In order to improve patient safety, a consortium of UK healthcare professionals with expertise in LVADs developed universally applicable prehospital emergency algorithms. Guidance was framed as closely as possible on the standard ABCDE approach to the assessment of critically ill patients.

INTRODUCTION OR BACKGROUND: Ambulance services have historically found their targets particularly challenging. This article explores some areas of this multifaceted problem. SOURCES OF DATA: Research articles, government publications and published audit data. AREAS OF AGREEMENT: Demand is increasing in many areas of healthcare, but whilst hospitals saw a 7% increase in demand in recent times, ambulance services saw nearly double that. The services ambulance trusts provide have evolved from that of a transport service to that of a mobile health provider, and they have become victims of their own success. AREAS OF CONTROVERSY: Ambulance targets have never evolved to match evolving care. Ambulance personnel strive to avoid hospital attendance where appropriate, but this can be difficult for a 24-hour service, when not all referral pathways have 24-hour referral systems. GROWING POINTS: We discuss why demand might be growing disproportionately for ambulance services, and challenge the appropriateness of the targets themselves. AREAS TIMELY FOR DEVELOPING RESEARCH: Possible formats for revised ambulance targets are discussed.

Introduction: Pre-hospital clinicians can expect to encounter patients with agitation, including acute behavioural disturbance (ABD). These situations carry significant risk for patients and emergency medical services. Advanced paramedics within the London Ambulance Service (LAS) are frequently tasked to these incidents. At present, little evidence exists regarding clinical decision-making and management of this patient group. We sought to explore the demographics of patients presenting with potential ABD and quantify the degree of agitation, physical restraint, effectiveness of chemical sedation and any associated complications. Methods: A retrospective analysis of pre-hospital clinical records for patients coded with ABD and attended by LAS advanced paramedics between 1 October 2019 and 30 September 2020. Sedation assessment tool (SAT) scores were used as the primary outcome measure. Results: A total of 237 patient records were identified. Of the patients, 147 (62%) were physically restrained and 104 (44%) were chemically sedated. Sedation was more commonly administered where patients were exposed to physical restraint. High SAT scores were associated with the administration of sedative agents and at higher doses. Of patients undergoing sedation, 89 (85%) had a SAT score reduction of 2 points or a final score ≤ 0. The mean SAT score reduction was 2.72. Three cases of minor injury were reported following physical restraint. Conclusion: Advanced paramedics undertook sedation in less than half the cohort, suggesting that other strategies such as communication and positioning were utilised. Most patients were managed into a state between being restless and rousable, largely negating the need for ongoing physical restraint during hospital transfer. Appropriately trained advanced paramedics can utilise sedation safely and effectively in selected cases.
RESUMO
A 3 month old boy, with no known health conditions, suffered a sudden collapse at home. On first EMS arrival, ventricular fibrillation (VF) cardiac arrest was identified and resuscitation following UK national guidelines was initiated. He remained in cardiac arrest for over 25 min, during which he received 10 defibrillation shocks, each effective, but with VF reoccurring within a few seconds of each of the first 9. A return of spontaneous circulation (ROSC) was achieved after the 10th shock. The resuscitation was conducted fully in his home, with the early involvement of Advanced Paramedic Practitioners specialising in critical care (APP- CC). Throughout his resuscitation, there remained a strong focus on delivering quality resuscitation in situ, rather than a 'load and go' approach that would have resulted in very early conveyance to hospital with on-going CPR.The patient was subsequently discharged home and is making an excellent recovery. The arrest was later determined to have been caused by a primary arrhythmia as a result of a previously unidentified non-obstructive variant hypertrophic cardiomyopathy.We present data downloaded from the defibrillator used during the resuscitation that illustrates clearly the recurrent nature of his fibrillation.

BACKGROUND: Out-of-hospital cardiac arrest carries a poor prognosis with survival less than 10% in many patient cohorts. Survival is inversely associated with duration of resuscitation as external chest compressions do not provide sufficient blood flow to prevent irreversible organ damage during a prolonged resuscitation. Extracorporeal membrane oxygenation (ECMO) instituted during cardiac arrest can provide normal physiological blood flows and is termed Extracorporeal Cardio-Pulmonary Resuscitation (ECPR). ECPR may improve survival when used with in-hospital cardiac arrests. This possible survival benefit has not been replicated in trials of out-of-hospital cardiac arrests, possibly because of the additional time it takes to transport the patient to hospital and initiate ECPR. Pre-hospital ECPR may shorten the time between cardiac arrest and physiological blood flows, potentially improving survival. It may also mitigate some of the neurological injury that many survivors suffer. METHODS: Sub30 is a prospective six patient feasibility study. The primary aim is to test whether it is possible to institute ECPR within 30 âmin of collapse in adult patients with refractory out of hospital cardiac arrest (OHCA). The secondary aims are to gather preliminary data on clinical outcomes, resource utilisation, and health economics associated with rapid ECPR delivery in order to plan any subsequent clinical investigation or clinical service. On study days a dedicated fast-response vehicle with ECPR capability will be tasked to out-of-hospital cardiac arrests in an area of London served by Barts Heart Centre. If patients suffer a cardiac arrest refractory to standard advanced resuscitation and meet eligibility criteria, ECPR will be started in the pre-hospital environment. DISCUSSION: Delivering pre-hospital ECPR within 30 âmin of an out-of-hospital cardiac arrest presents significant ethical, clinical, governance and logistical challenges. Prior to conducting an efficacy study of ECPR the feasibility of timely and safe application must be demonstrated first. Extensive planning, multiple high-fidelity multiagency simulations and a unique collaboration between pre-hospital and in-hospital institutions will allow us to test the feasibility of this intervention in London. The study has been reviewed, refined and endorsed by the International ECMO Network (ECMONet). TRIAL REGISTRATION: Clinicaltrials. gov NCT03700125, prospectively registered October 9, 2018.

OBJECTIVES: To describe the epidemiology of assaults resulting in stab injuries among young people. We hypothesised that there are specific patterns and risk factors for injury in different age groups. DESIGN: Eleven-year retrospective cohort study. SETTING: Urban major trauma centre in the UK. PARTICIPANTS: 1824 patients under the age of 25 years presenting to hospital after a stab injury resulting from assault. OUTCOMES: Incident timings and locations were obtained from ambulance service records and triangulated with prospectively collected demographic and injury characteristics recorded in our hospital trauma registry. We used geospatial mapping of individual incidents to investigate the relationships between demographic characteristics and incident timing and location. RESULTS: The majority of stabbings occurred in males from deprived communities, with a sharp increase in incidence between the ages of 14 and 18 years. With increasing age, injuries occurred progressively later in the day (r2=0.66, p<0.01) and were less frequent within 5 km of home (r2=0.59, p<0.01). Among children (age <16), a significant peak in injuries occurred between 16:00 and 18:00 hours, accounting for 22% (38/172) of injuries in this group compared with 11% (182/1652) of injuries in young adults. In children, stabbings occurred earlier on school days (hours from 08:00: 11.1 vs non-school day 13.7, p<0.01) and a greater proportion were within 5 km of home (90% vs non-school day 74%, p=0.02). Mapping individual incidents demonstrated that the spike in frequency in the late afternoon and early evening was attributable to incidents occurring on school days and close to home. CONCLUSIONS: Age, gender and deprivation status are potent influences on the risk of violent injury in young people. Stab injuries occur in characteristic temporal and geographical patterns according to age group, with the immediate after-school period associated with a spike in incident frequency in children. This represents an opportunity for targeted prevention strategies in this population.

The participation of volunteers in the National Health Service (NHS) has been actively promoted during recent years, particularly within community and primary healthcare services (National Health Service 1996, 1998). As a consequence, volunteers currently make a significant contribution to health and social care within the UK. Concerning this contribution, the literature often portrays the volunteers' role as one of providing social support. In the present paper, the authors attempt to explore this role in more detail, drawing on interview data from studies of two separate volunteer programmes. One of these considered the role of volunteers supporting older hospitalised patients (Davies et al. 2001), and the other was based within general practice (Faulkner 2003, 2004). The social support provided by these programmes is considered from the perspective of four broad support mechanisms described by Langford et al. (1997), namely: emotional support; informational support; appraisal support; and instrumental support. Secondary analysis examines the potential contribution of volunteers to patient well-being.

This qualitative study describes and analyses the key features of a practice based voluntary referral service called the Patient Support Service (PSS). This involved collecting interview data from 11 service users and 8 service providers, which was analysed using 'Framework,' a qualitative method of applied policy research. The study findings describe the PSS, its perceived effectiveness and barriers to service provision. Following this, a series of strategic recommendations for service development are presented. It is concluded that voluntary patient referral services, such as the PSS, broaden the referral options available for managing patients with psychosocial problems in primary care.

The sick role is a complex behaviour that allows a person who is ill to depend on carers. This article discusses the parameters of the sick role, explains how it is prompted by admission to hospital and asks whether it can act as a barrier to patients' participation in decisions on their care. It considers why some patients are reluctant to relinquish the sick role and suggests ways for nurses to help these patients to play an active part in their own recovery.

OBJECTIVE: To develop and validate a prognostic model for early death in patients with traumatic bleeding. DESIGN: Multivariable logistic regression of a large international cohort of trauma patients. SETTING: 274 hospitals in 40 high, medium, and low income countries PARTICIPANTS: Prognostic model development: 20,127 trauma patients with, or at risk of, significant bleeding, within 8 hours of injury in the Clinical Randomisation of an Antiï¬brinolytic in Signiï¬cant Haemorrhage (CRASH-2) trial. External validation: 14,220 selected trauma patients from the Trauma Audit and Research Network (TARN), which included mainly patients from the UK. OUTCOMES: In-hospital death within 4 weeks of injury. RESULTS: 3076 (15%) patients died in the CRASH-2 trial and 1765 (12%) in the TARN dataset. Glasgow coma score, age, and systolic blood pressure were the strongest predictors of mortality. Other predictors included in the final model were geographical region (low, middle, or high income country), heart rate, time since injury, and type of injury. Discrimination and calibration were satisfactory, with C statistics above 0.80 in both CRASH-2 and TARN. A simple chart was constructed to readily provide the probability of death at the point of care, and a web based calculator is available for a more detailed risk assessment (http://crash2.lshtm.ac.uk). CONCLUSIONS: This prognostic model can be used to obtain valid predictions of mortality in patients with traumatic bleeding, assisting in triage and potentially shortening the time to diagnostic and lifesaving procedures (such as imaging, surgery, and tranexamic acid). Age is an important prognostic factor, and this is of particular relevance in high income countries with an aging trauma population.

AIM: This paper reports the development and initial testing of the combined assessment of residential environments (CARE) profiles, which identify the frequency of positive events over a specified time based on the perceptions of residents, relatives and staff in care home settings. BACKGROUND: Despite the well-known benefits of positive events for subjective well-being, little is known about the nature of positive events experienced by residents, relatives and staff in care homes. There is also a dearth of tools capable of systematically evaluating how frequently these events occur in this context. METHODS: The CARE profiles were developed and tested between February 2004 and June 2005 with a combined sample of 372 residents, relatives and staff drawn from 11 care homes. An Event Frequency Approach was adopted to create three questionnaires (residents, relatives and staff), each containing 30 consensually valid positive events. The thematic content of these events was balanced for each questionnaire using the Senses Framework as a theoretical model. Once completed, the CARE profiles were tested in four care homes. RESULTS: Test data from the CARE profiles were used to produce a bar chart showing median frequencies of positive events experienced by residents, relatives and staff during the timeframe in question (e.g. 1 month). These profiles were shown to be internally consistent, with alpha scores ranging from 0.70 to 0.89 for residents, 0.91 to 0.94 for relatives and 0.78 to 0.92 for staff. CONCLUSION: We envisage that feedback from the CARE profiles will both reinforce good care home practice and identify areas for change based on the experiences of all major stakeholders. However, further development of the profiles is needed if the experiences of cognitively impaired residents are to be included in the assessment process.
