Introduction: Dementia is a common co-morbidity in older people who require urgent or emergency ambulance attendance and influences clinical decisions and care pathways. Following an initial audit of dementia data and consultation with staff, a specific section (tab) to record dementia was introduced on an ambulance service electronic patient record (ePR). This includes a dementia diagnosis button and a free-text section. We aimed to assess whether and how this improved recording. Methods: To re-audit the proportion of ambulance ePRs where dementia is recorded for patients aged ≥65 years, and to describe the frequency of recording in patients aged <65; to analyse discrepancies in the place of recording dementia on the ePR by comparing data from the new dementia tab and other sections of the ePR. Results: We included 112,193 ePRs of patients aged ≥65 with ambulance attendance from a six-month period. The proportion with dementia recorded in patients aged ≥65 was 16.5%, increasing to 19.9% in patients aged ≥75, as compared to 13.5% (≥65) and 16.5% (≥75) in our previous audit. In this audit, of the 16.5% (n = 18,515) of records with dementia recorded, 69.9% (n = 12,939) used the dementia button and 25.4% (n = 4704) recorded text in the dementia tab. Dementia was recorded in ePR free-text fields (but not the dementia tab) in 29.7% of records. Eighteen other free-text fields were used in addition to, or instead of, the dementia tab, including the patient's social history, previous medical history and mental health. Dementia was present on the ePR of 0.4% (n = 461) of patients aged <65. Conclusions: An ePR dementia tab enabled ambulance clinicians to standardise the location of recording dementia and may have facilitated increased recording. We would recommend other ambulance trusts capture this information in a specific section to improve information sharing and to inform care planning for this patient group. [ABSTRACT FROM AUTHOR]

Introduction: Older people, especially those with dementia, have a high risk of deterioration following admission to hospital. More than 60% of older people attended by South Central Ambulance Service (SCAS) clinicians are conveyed to hospital, although many conveyances may not have been due to life-threatening conditions. We aimed to understand patterns of conveyance and alternative referral pathways used following ambulance attendance to an older person. Methods: Service evaluation, using routinely collected, anonymised electronic records. Participants: Electronic records of people aged ≥75 years for whom an ambulance was dispatched between April 2016 and March 2017 within the geographical boundaries of SCAS NHS Foundation Trust, who were alive on arrival of the ambulance. Conveyance rates are described according to patient and emergency-call characteristics. Logistic regression was used to produce adjusted odds ratios for conveyance. Alternative referral pathways used are described. Results: Of 110,781 patients attended, 64% were conveyed to hospital. Factors associated with reduced odds of conveyance included out-of-hours calls (adjusted odds ratio (aOR) 0.82 [0.79-0.85]), living alone with a care package or with family plus care package (aOR 0.66 [0.62-0.69]; aOR 0.58 [0.54-0.62] respectively) and a record of dementia (0.91 [0.87-0.96]). Living in a nursing home was associated with an increased risk of conveyance (aOR 1.25 [1.15-1.36]). Patients with dementia with more income were significantly less likely to be conveyed than those with less income. Alternative referral services were used in 22% of non-conveyed patients, most commonly GP, out-of-hours and falls services. Discussion: People aged ≥75 years have high rates of conveyance, which are influenced by factors such as out-of-hours calls, dementia and receipt of social care. Low use of alternative referral services may reflect limited availability or difficulty in access. A better understanding of how these factors influence ambulance clinician decision-making is integral to improvement of outcomes for older people. [ABSTRACT FROM AUTHOR]

Background: Dementia is common in older adults assessed by ambulance services. However, inconsistent reporting via the patient record may result in this diagnosis being overlooked by healthcare staff further down the care pathway. This can have a deleterious effect on subsequent patient care, increasing morbidity and mortality. We sought to understand how and where ambulance staff would like to record this finding on the electronic patient record (ePR). Methods: We designed and implemented a survey of ambulance staff in a single service to understand how they identify patients with dementia, how they record dementia on the ePR and how the ePR could be improved to better capture dementia. Scoping questions on frailty were included. The survey was tested using cognitive interviewing. Analysis was conducted using descriptive statistics for closed questions and thematic analysis for open questions as appropriate. Results: 131 surveys were completed; 60% of participants were paramedics and 40% were other grades of front line staff. Participants reported consulting electronic/paper sources, and individuals such as carers involved in the patients' care, to establish whether dementia had been diagnosed. Frailty assessments were prompted by social context, reduced mobility, a fall or diagnosis of dementia. Staff reported documenting dementia in 20 different areas on the ePR and 46% of participants stated a preference for a designated area to record the information. However, 15% indicated it was not necessary to record dementia or that no ePR changes were required. Conclusions: We have highlighted the variation in ambulance staff practice in recording of dementia. Alterations to the ePR are required to ensure that dementia is recorded consistently and is easily retrievable. Clearer guidance on when to assess frailty may also enhance information provision to care staff in other sectors, resulting in more appropriate clinical and social care. [ABSTRACT FROM AUTHOR]

Background: Pain is a common symptom among patients presenting to ambulance services and is often associated with traumatic injury. Assessment and management of pain in children in the pre-hospital setting is suboptimal. This study aimed to understand the facilitators and barriers experienced by paramedics in their assessment and management of pain in children who have sustained traumatic injuries. Methods: Face-to-face, audio-recorded semi-structured interviews using a piloted topic guide were conducted with paramedics employed by South Central Ambulance Service NHS Foundation Trust. Interviews were professionally transcribed, coded manually and analysed using thematic analysis. Results: Eleven interviews were conducted; three themes related to assessment and three related to management were identified. Previous positive experiences of utilising pain scoring tools were identified as a facilitator to pain assessment, whereas a lack of confidence in using pain scoring tools was a barrier. Patients' understanding of and compliance with the tools were both a facilitator and a barrier to assessment. Facilitators to management included personal sub-themes of colleagues/others, exposure, being a parent, technology, severity of the injury and subjective pain scoring. Organisational facilitators included medicines, routes, and alternative methods. Situational facilitators included patient-specific solutions and parents. Five personal barriers to management included medicines, skill, consequences to self or patient, negative interactions, and limited exposure. Three organisational barriers included medicines and routes, equipment issues and choices, and training and culture. Within the theme of situation, two sub-themes emerged: patient-specific issues and environment-specific issues. Novel facilitators to emerge were those of alternative methods and being a parent. Conclusion: A multitude of factors incorporating situational, organisational, and personal all combine to determine how paramedics treat paediatric trauma patients. A multi-stakeholder approach to providing clearer assessment tools, improved education, equipment, and pharmacy options may improve assessment and management compliance for the benefit of the patient.

Background\ud \ud Concern about the use of epinephrine as a treatment for out-of-hospital cardiac arrest led the International Liaison Committee on Resuscitation to call for a placebo-controlled trial to determine whether the use of epinephrine is safe and effective in such patients.\ud \ud Methods\ud \ud In a randomized, double-blind trial involving 8014 patients with out-of-hospital cardiac arrest in the United Kingdom, paramedics at five National Health Service ambulance services administered either parenteral epinephrine (4015 patients) or saline placebo (3999 patients), along with standard care. The primary outcome was the rate of survival at 30 days. Secondary outcomes included the rate of survival until hospital discharge with a favorable neurologic outcome, as indicated by a score of 3 or less on the modified Rankin scale (which ranges from 0 [no symptoms] to 6 [death]).\ud \ud Results\ud \ud At 30 days, 130 patients (3.2%) in the epinephrine group and 94 (2.4%) in the placebo group were alive (unadjusted odds ratio for survival, 1.39; 95% confidence interval [CI], 1.06 to 1.82; P=0.02). There was no evidence of a significant difference in the proportion of patients who survived until hospital discharge with a favorable neurologic outcome (87 of 4007 patients [2.2%] vs. 74 of 3994 patients [1.9%]; unadjusted odds ratio, 1.18; 95% CI, 0.86 to 1.61). At the time of hospital discharge, severe neurologic impairment (a score of 4 or 5 on the modified Rankin scale) had occurred in more of the survivors in the epinephrine group than in the placebo group (39 of 126 patients [31.0%] vs. 16 of 90 patients [17.8%]).\ud \ud Conclusions\ud \ud In adults with out-of-hospital cardiac arrest, the use of epinephrine resulted in a significantly higher rate of 30-day survival than the use of placebo, but there was no significant between-group difference in the rate of a favorable neurologic outcome because more survivors had severe neurologic impairment in the epinephrine group.

- Abstract
Background: The 'Prehospital Assessment of the Role of Adrenaline: Measuring the Effectiveness of Drug Administration In Cardiac Arrest' (PARAMEDIC2) trial showed that adrenaline improves overall survival, but not neurological outcomes. We sought to determine the within-trial and lifetime health and social care costs and benefits associated with adrenaline, including secondary benefits from organ donation.Methods: We estimated the costs, benefits (quality-adjusted life years (QALYs)) and incremental cost-effectiveness ratios (ICERs) associated with adrenaline during the 6-month trial follow-up. Model-based analyses explored how results altered when the time horizon was extended beyond 6 months and the scope extended to include recipients of donated organs.Results: The within-trial (6 months) and lifetime horizon economic evaluations focussed on the trial population produced ICERs of £1,693,003 (€1,946,953) and £81,070 (€93,231) per QALY gained in 2017 prices, respectively, reflecting significantly higher mean costs and only marginally higher mean QALYs in the adrenaline group. The probability that adrenaline is cost-effective was less than 1% across a range of cost-effectiveness thresholds. Combined direct economic effects over the lifetimes of survivors and indirect economic effects in organ recipients produced an ICER of £16,086 (€18,499) per QALY gained for adrenaline with the probability that adrenaline is cost-effective increasing to 90% at a £30,000 (€34,500) per QALY cost-effectiveness threshold.Conclusions: Adrenaline was not cost-effective when only directly related costs and consequences are considered. However, incorporating the indirect economic effects associated with transplanted organs substantially alters cost-effectiveness, suggesting decision-makers should consider the complexity of direct and indirect economic impacts of adrenaline.Trial Registration: ISRCTN73485024 .

Introduction: Out-of-hospital cardiac arrest trials can prove challenging and there is a need to share learning from those that have recruited successfully. We have just completed three years of recruitment to PARAMEDIC2, a placebo-controlled trial of adrenaline in out-of-hospital cardiac arrest. This study was designed to describe the experience of operational ambulance staff involved in recruiting patients into PARAMEDIC2. Methods: Four focus groups involving trial paramedics and supporting members of the emergency care team were conducted across different geographical regions of a single UK ambulance service participating in the PARAMEDIC2 study. Data analysis was supported by NVivo 12 and themes were identified using a thematic analysis approach. Results: Forty-four participants contributed to the focus groups. Four overarching themes were identified: context for the research, ethical concerns, concerns at the patient's side and ongoing trial support. Participants felt that research such as PARAMEDIC2 is important and necessary to drive medical progress. They valued the opportunity to be part of a large project. Due to the deferred consent model employed, public awareness of the trial was felt to be important. Most expressed equipoise regarding adrenaline, but some felt concerned about enrolling younger patients and there was discussion around what constitutes a successful outcome. Struggles with ethical concerns were overcome through training and one-to-one discussion with research paramedics. Participants valued feedback on their performance of trial tasks, but also wanted feedback on their resuscitation skills. Cardiac arrest places a high cognitive demand on paramedics; simplicity and reinforcement of trial processes were key to facilitating recruitment. Caring for relatives was a high priority for paramedics and some felt conflicted about not discussing the trial with them. Conclusions: This study has provided insights into paramedic experience of a large-scale prehospital trial. Investment in time and resource to provide face-to-face training and personalised feedback to paramedics can foster engagement and optimise performance. [ABSTRACT FROM AUTHOR]

- Abstract
Objective: We aimed to identify how patient (age, sex, condition) and paramedic factors (sex, role) affected prehospital analgesic administration and pain alleviation.Methods: We used a cross-sectional design with a 7-day retrospective sample of adults aged 18 years or over requiring primary emergency transport to hospital, excluding patients with Glasgow Coma Scale below 13, in two UK ambulance services. Multivariate multilevel regression using Stata 14 analysed factors independently associated with analgesic administration and a clinically meaningful reduction in pain (≥2 points on 0-10 numerical verbal pain score [NVPS]).Results: We included data on 9574 patients. At least two pain scores were recorded in 4773 (49.9%) patients. For all models fitted there was no significant relationship between analgesic administration or pain reduction and sex of the patient or ambulance staff. Reduction in pain (NVPS ≥2) was associated with ambulance crews including at least one paramedic (odds ratio [OR] 1.52, 95% confidence interval [CI] 1.14 to 2.04, p < 0.01), with any recorded pain score and suspected cardiac pain (OR 2.2, 95% CI 1.02 to 4.75). Intravenous morphine administration was also more likely where crews included a paramedic (OR 2.82, 95% CI 1.93 to 4.13, P < 0.01), attending patients aged 51 to 64 years (OR 2.04, 95% CI 1.21 to 3.45, p = 0.01), in moderate to severe (NVPS 4-10) compared with lower levels of pain for any clinical condition group compared with the reference condition.Conclusion: There was no association between patient sex or ambulance staff sex or grade and analgesic administration or pain reduction.

- Abstract
Objectives There is considerable interest in reducing the cost of clinical trials. Linkage of trial data to administrative datasets and disease-specific registries may improve trial efficiency, but it has not been reported in resuscitation trials conducted in the UK. To assess the feasibility of using national administrative and clinical datasets to follow up patients transported to hospital following attempted resuscitation in a cluster randomised trial of a mechanical chest compression device in out-of-hospital cardiac arrest. Methods Hospital data on trial participants were requested from Hospital Episode Statistics (HES), the Intensive Care National Audit and Research Centre, and Myocardial Ischaemia National Audit Project and National Audit of Percutaneous Coronary Interventions, using unique patient identifiers. Linked data were received between June 2014 and June 2015. Results Of 4471 patients randomised in the pre-hospital randomised assessment of a mechanical compression device in cardiac arrest (PARAMEDIC) trial, 2398 (53.6%) were not known to be deceased at emergency department arrival and were eligible for linkage. We achieved an overall match rate of 86.7% in the combined HES accident and emergency, inpatient and critical care dataset, with variable match rates (4.2%-80.4%) in individual datasets. Patient demographics, cardiac arrest-related characteristics and major outcomes were predominantly similar between HES matched and unmatched groups, in the linkage apart from location, response time and return of spontaneous circulation (ROSC) at handover. Conclusions This study shows that it is feasible to track patients from the prehospital setting through to hospital admission using routinely available administrative datasets with a moderate to high degree of success. This approach has the potential to complement the trial data with the demographic and clinical management information about the studied cohort, as well as to improve the efficiency and reduce the costs of follow-up in cardiac arrest trials.

Background: Dementia is a common diagnosis in older people. It is important to identify and record dementia on emergency call-outs, as it impacts on subsequent care decisions. Ambulance services are changing from paper to electronic patient records, but there are limited data on how frequently and in which sections of the electronic patient record dementia is being recorded. Aims: To audit the proportion of ambulance electronic patient records where dementia is recorded for patients aged (i) 65 and above and (ii) 75 and above, and to describe the sections in the electronic patient record in which dementia is recorded, as there is currently no standardised button or field available. Results: A total of 314,786 electronic patient records were included in the audit, over a one-year period. The proportion of attended calls with 'dementia' recorded in the electronic patient record in patients aged 65+ was 13.5%, increasing to 16.5% in patients aged 75+, which is similar to that recorded in previous literature. For patients aged 75+ conveyed to hospital, 15.2% had 'dementia' recorded in the electronic patient record, which may indicate under-recording. Recording of dementia between Clinical Commissioning Groups varied between 11.0% and 15.3%. Dementia was recorded in 16 different free-text fields, and 38.4% of records had dementia recorded in more than one field. Conclusion: This audit demonstrates high variability in both the frequency of recording dementia and also the location in the electronic patient record. To ensure consistent recording and ease of retrieval to inform patient care and handover, we propose that the electronic patient record should be modified to reflect paramedics' needs, and those of the healthcare staff who receive and act on the report. Enhanced training for paramedics in the importance and method of recording dementia is required. Future data will enable accurate monitoring of trends in conveyance, and inform justifications for alternative services and novel referral pathways. [ABSTRACT FROM AUTHOR]

- Abstract
Background: There is an urgent need to develop prehospital research capability in order to improve the care of patients presenting to emergency medical services (EMS). The Prehospital Randomised Assessment of a Mechanical compression Device In Cardiac arrest trial, a pragmatic cluster randomised trial evaluating the LUCAS-2 device, represents the largest randomised controlled trial conducted by UK ambulance services to date. The aim of this study was to identify and analyse factors that may influence paramedic attitudes to, and participation in, clinical trials.Methods: Personal and organisational experience from this trial was assessed by feedback from a workshop attended by collaborators from participating EMS and a survey of EMS personnel participating in the trial. A work systems model was used to explain the impact of five interwoven themes-person, organisation, tasks, tools & technology and environment-on trial conduct including gathering of high-quality data.Results: The challenge of training a geographically diverse EMS workforce required development of multiple educational solutions. In order to operationalise the trial protocol, internal organisational relationships were perceived as essential. Staff perceptions of the normalisation of participation and ownership of the trial influenced protocol compliance rates. Undertaking research was considered less burdensome when additional tasks were minimised and more difficult when equipment was unavailable. The prehospital environment presents practical challenges for undertaking clinical trials, but our experience suggests these are not insurmountable and should not preclude conducting high-quality research in this setting.Conclusions: Application of a human factors model to the implementation of a clinical trial protocol has improved understanding of the work system, which can inform the future conduct of clinical trials and foster a research culture within UK ambulance services.Trial Registration Number: ISRCTN08233942.

Two-hundred-and-seventy-nine patients (103 men, 176 women) were followed-up 1-2 years after an act of non-fatal deliberate self-harm. Of 155 patients offered a psychiatric out-patient appointment at the time, only 68 completed the treatment. A further act of deliberate self-harm was committed by 26 men and 41 women within twelve months. The factors most highly associated with repetition were previous psychiatric treatment, a previous act of deliberate self-harm, and a criminal record. These factors held good for a separate series of patients. Significantly more repeaters received prolonged psychiatric care after the initial episode of deliberate self-harm. The implications of these findings for the clinical management of such patients are discussed. [ABSTRACT FROM AUTHOR]

In this study 368 patients were interviewed after they had attended the Bristol Royal Infirmary Accident and Emergency Department following a non-fatal act of deliberate self-harm. There were twice as many women (247) as men (121), and two thirds of the patients were in the 15-35 age group. Ninety-five per cent had taken a drug overdose, most commonly one or more of the tranquillizers, antidepressants, hypnotics or analgesics. Seventy-eight per cent had taken drugs prescribed by a doctor. Half the patients mentioned interpersonal conflict as a major precipitating factor in the episode. A psychiatric diagnosis was completed for all admitted patients, of whom 52 per cent were considered to be suffering from neurotic depression, 29 per cent from personality disorder, 12 per cent from functional psychosis and 10 per cent from alcohol addiction. Almost half had deliberately harmed themselves on a previous occasion. The series showed a greater than average incidence of unemployment, overcrowded living conditions, divorce and antisocial behaviour. The implications of these findings for the clinical management and prevention of non-fatal deliberate self-harm are discussed. [ABSTRACT FROM AUTHOR]

1. The incidence of non-fatal deliberate self-harm throughout the City of Bristol during 1972 and 1973 was assessed by means of a survey of patients presenting to Accident and Emergency Departments of hospitals in the area. Fatal or repeated acts of self-harm were not included in the survey. 2. The rates for females exceeded those for males at all ages, with peak incidence of 645 per 100,000 females (age group 15-29 years) and 334 per 100,000 males (age group 25-29 years). Ninety-three per cent had taken a drug overdose of some kind. 3. The problem was found in all electoral wards of tE CITY, THOUGH ITS DISTRIBUTION WAS MARKEDLY CENTRIPETAL, WITH A CENTRAL AREA HAVING MORBIDITY RATES UP TO 2-8 TIMES THAT FOR THE CITY AS A WHOLE. 4. The socio-economic correlates of deliberate self-harm were examined by reference both to a series of 368 patients interviewed soon after the event and to the pattern of its distribution throughout the city. A significant positive association was found with areas of overcrowding, lack of exclusive domestic amenities and high proportion of foreign born residents, but there was no correlation with the proportion of persons living alone nor with the type of accommodation. 5. The central high rate area was found to be heterogeneous in socio-economic terms, ranging from a student and young professionals' bed-sitter area to one with a high proportion of unskilled manual labourers and New Commonwealth immigrants. 6. The aetiological implications of the ecological findings for deliberate self-harm throughout the city are discussed. [ABSTRACT FROM AUTHOR]

- Abstract
The article provides information on managing psychological trauma. Study was conducted and researchers found an association between the type of cognitive appraisals made at the time and the degree of subsequent coping. It states that relying on past memories is the limitation of this research. It also mentions that as workload increases and diversifies, adaptive coping mechanisms is more relevant to the paramedic profession.

- Abstract
Purpose of Review: Mechanical chest compression devices are increasingly deployed during cardiopulmonary resuscitation. We discuss the data supporting the use of mechanical chest compression devices during cardiac arrest and provide an opinion about the future of the technology., Recent Findings: Multiple randomized trials investigating the use of mechanical chest compression devices for out-of-hospital cardiac arrest have not demonstrated improved outcomes. There is little prospective evidence to support the use of mechanical chest compression devices in other settings. Data from observational studies do not support the routine use of mechanical chest compression devices for in-hospital cardiac arrest, but there may be a role for mechanical chest compressions for cardiac arrest in procedural areas and cardiac arrest prior to cannulation for extracorporeal membrane oxygenation., Summary: Mechanical chest compression devices offer a solution to some of the human limiting factors of resuscitation, but have failed to demonstrate meaningful improvement in outcomes from cardiac arrest. Routine use of mechanical chest compression devices during cardiac arrest is not supported by evidence., (Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.)

- Abstract
Objective: This review summarises the current evidence base for combinations of neuroprotective CPR adjuncts (active compression-decompression chest compressions, impedance threshold devices, and head-up positioning) during out-of-hospital cardiac arrest., Methods: A systematic search (PROSPERO registration CRD42023432302) was performed in English on MEDLINE, EMBASE, and the Cochrane Library in August 2023, and repeated in February 2024. All randomised and observational studies (not abstracts) reporting on any combination of the aforementioned CPR adjuncts were included. Papers were screened independently by two researchers, with a third reviewer acting as tiebreaker. Out-of-hospital, non-traumatic, cardiac arrests in patients >18 years were eligible for inclusion. Risk of bias was assessed using the Risk of Bias 2 tool and the Newcastle-Ottawa scale., Results: Eight of 1172 unique articles identified in the initial searches were included, with five randomised controlled trials and three observational studies. No randomised trial investigated a bundle of all three interventions. All randomised controlled trials were at intermediate or high risk of bias. Neurologically favourable survival was greater in patients treated with an impedance threshold device and active compression-decompression CPR when compared to standard CPR (8.9% vs 5.8%, p = 0.019) in the largest existing randomised trial. Conflicting results were found in observational studies comparing the complete neuroprotective bundle to standard CPR., Conclusions: This review was limited by small study numbers and overlapping samples, which precluded a meta-analysis. Limited data suggests that combinations of adjuncts to improve cerebral perfusion during CPR may improve survival with favourable neurological outcome. A randomised controlled trial is required to establish whether combining all three together results in improved outcomes., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.

- Abstract
Background: The recruitment of patients to emergency research studies without the requirement for prior informed consent has furthered the conduct of randomised studies in cardiac arrest. Frameworks enabling this vary around the world depending on local legal or ethical requirements. When an enrolled patient does not survive, researchers may take one of three approaches to inform relatives of their enrolment: a direct (active) approach, providing information indirectly (passively) and inviting relatives to seek further information if they choose, or providing no information about the trial (no attempt). Previous studies have described experiences of US researchers' active approach but there is little known about approaches elsewhere.We aimed to conduct a structured investigation of methods used in cardiac arrest trials to provide information about trial enrolment to relatives of non-surviving patients., Methods: We systematically searched trial registries to identify randomised clinical trials that recruited cardiac arrest patients. Trials were eligible for inclusion if they recruited adults during cardiac arrest (or within 1 hour of return of spontaneous circulation) between 2010 and 2022 (in the decade prior to study conception). We extracted data from trial registries and, where relevant, published papers and protocols. Investigators were contacted and asked to describe the style, rationale and timing of approach to relatives of non-surviving patients. We present descriptive statistics., Results: Our trial registry search identified 710 unique trials, of which 108 were eligible for inclusion. We obtained information from investigators for 64 (62%) trials. Approximately equal numbers of trials attempted to actively inform relatives of non-survivors (n=28 (44% (95% CI; 31% to 57%))), or made no attempt (n=25 (39% (95% CI; 27% to 52%))). The remaining studies provided general information about the trial to relatives but did not actively inform them (n=11 (17% (95% CI; 8% to 29%)))., Conclusions: There is wide variability in the approach taken to informing relatives of non-surviving patients enrolled in cardiac arrest randomised clinical trials., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

- Abstract
Objectives: To evaluate oxygen saturation and vital signs measured in the community by emergency medical services (EMS) as clinical markers of COVID-19-positive patient deterioration., Design: A retrospective data analysis., Setting: Patients were conveyed by EMS to two hospitals in Hampshire, UK, between 1 March 2020 and 31 July 2020., Participants: A total of 1080 patients aged ≥18 years with a COVID-19 diagnosis were conveyed by EMS to the hospital., Primary and Secondary Outcome Measures: The primary study outcome was admission to the intensive care unit (ICU) within 30 days of conveyance, with a secondary outcome representing mortality within 30 days of conveyance. Receiver operating characteristic (ROC) analysis was performed to evaluate, in a retrospective fashion, the efficacy of different variables in predicting patient outcomes., Results: Vital signs measured by EMS staff at the first point of contact in the community correlated with patient 30-day ICU admission and mortality. Oxygen saturation was comparably predictive of 30-day ICU admission (area under ROC (AUROC) 0.753; 95% CI 0.668 to 0.826) to the National Early Warning Score 2 (AUROC 0.731; 95% CI 0.655 to 0.800), followed by temperature (AUROC 0.720; 95% CI 0.640 to 0.793) and respiration rate (AUROC 0.672; 95% CI 0.586 to 0.756)., Conclusions: Initial oxygen saturation measurements (on air) for confirmed COVID-19 patients conveyed by EMS correlated with short-term patient outcomes, demonstrating an AUROC of 0.753 (95% CI 0.668 to 0.826) in predicting 30-day ICU admission. We found that the threshold of 93% oxygen saturation is prognostic of adverse events and of value for clinician decision-making with sensitivity (74.2% CI 0.642 to 0.840) and specificity (70.6% CI 0.678 to 0.734)., Competing Interests: Competing interests: MI-K is the National Clinical Lead Deterioration and National Specialist Advisor Sepsis, NHS England and NHS Improvement., (© Author(s) (or their employer(s)) 2024.

- Abstract
Aims: The PARAMEDIC-3 trial evaluates the clinical and cost-effectiveness of an intraosseous first strategy, compared with an intravenous first strategy, for drug administration in adults who have sustained an out-of-hospital cardiac arrest., Methods: PARAMEDIC-3 is a pragmatic, allocation concealed, open-label, multi-centre, superiority randomised controlled trial. It will recruit 15,000 patients across English and Welsh ambulance services. Adults who have sustained an out-of-hospital cardiac arrest are individually randomised to an intraosseous access first strategy or intravenous access first strategy in a 1:1 ratio through an opaque, sealed envelope system. The randomised allocation determines the route used for the first two attempts at vascular access. Participants are initially enrolled under a deferred consent model.The primary clinical-effectiveness outcome is survival at 30-days. Secondary outcomes include return of spontaneous circulation, neurological functional outcome, and health-related quality of life. Participants are followed-up to six-months following cardiac arrest. The primary health economic outcome is incremental cost per quality-adjusted life year gained., Conclusion: The PARAMEDIC-3 trial will provide key information on the clinical and cost-effectiveness of drug route in out-of-hospital cardiac arrest.Trial registration: ISRCTN14223494, registered 16/08/2021, prospectively registered., Competing Interests: The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: GDP is co-chair of the International Liaison Committee on Resuscitation (ILCOR).

- Abstract
Aims: The Prehospital Optimal Shock Energy for Defibrillation (POSED) study will assess the feasibility of conducting a cluster randomised controlled study of clinical effectiveness in UK ambulance services to identify the optimal shock energy for defibrillation., Methods: POSED is a pragmatic, allocation concealed, open label, cluster randomised, controlled feasibility study. Defibrillators within a single UK ambulance service will be randomised in an equal ratio to deliver one of three shock strategies 120-150-200 J, 150-200-200 J, 200-200-200 J. Consecutive adults (≥18 years) presenting with out of hospital cardiac arrest requiring defibrillation will be eligible. The study plans to enrol 90 patients (30 in each group). Patients (or their relatives for non-survivors) will be informed about trial participation after the initial emergency has resolved. Survivors will be invited to consent to participate in follow-up (i.e., at 30 days or discharge).The primary feasibility outcome is the proportion of eligible patients who receive the randomised study intervention. Secondary feasibility outcomes will include recruitment rate, adherence to allocated treatment and data completeness. Clinical outcomes will include Return of an Organised Rhythm (ROOR) at 2 minutes post-shock, refibrillation rate, Return of Spontaneous Circulation (ROSC) at hospital handover, survival and neurological outcome at 30 days ., Conclusion: The POSED study will assess the feasibility of a large-scale trial and explore opportunities to optimise the trial protocol.

Pocock H, Deakin CD, Lall R, Smith CM, and Perkins GD
- Abstract
Aim: To determine the optimal first-shock energy level for biphasic defibrillation and whether fixed or escalating protocols for subsequent shocks are most effective., Methods: We searched Medline, Embase, Cochrane CENTRAL, CINAHL, the Web of Science and national and international trial registry databases for papers published from database inception to January 2022. We reviewed reference lists of key papers to identify additional references. The population included adults sustaining non traumatic out-of-hospital cardiac arrest subject to attempted defibrillation. Studies of internal or monophasic defibrillation and studies other than randomised controlled trials or prospective cohorts were excluded. Two reviewers assessed study relevance. Data extraction and risk of bias assessment, using the ROBINS-I tool, were conducted by one reviewer and checked by a second reviewer. Data underwent intention-to-treat analysis., Results: We identified no studies evaluating first shock energy. Only one study ( n = 738) comparing fixed versus escalating energy met eligibility criteria: a prospective cohort analysis of a randomised controlled trial of manual versus mechanical CPR. High fixed (360 J) energy was compared with an escalating (200-200/300-360 J) strategy. Researchers found 27.5% (70/255) of patients in the escalating energy group and 27.61% (132/478) in the fixed high energy group survived to hospital discharge (unadjusted risk ratio 0.99, 95% CI 0.73, 1.23). Results were of very low certainty as the study was at serious risk of bias., Conclusion: This systematic review did not identify an optimal first-shock energy for biphasic defibrillation. We identified no survival advantage at 30 days when comparing 360 J fixed with 200 J escalating strategy., (© 2022 The Author(s).)
