Background: Inappropriate use of emergency health services and increasing admission to emergency services (ES) are universal problems. Objectives: This study aimed to evaluate the appropriateness of using prehospital emergency health services and triage performance in the ES.Methods: Patients over 18 who were transported to the emergency service were included in the study. Data were obtained by screening Turkish Prehospital Ambulance Services (112 Emergency Medical Services) case forms, hospital information recording systems, and patient files. The emergency status of the patients, medical records, International Classification of Diseases-10 (ICD-10) diagnosis codes, triage categories, vital signs, and the necessity for hospitalization were evaluated according to the International List of 32 Emergency Parameters.Results: The study included 1029 cases. The median age of the patients was 51.0 years, and 51.0% were male. 112 Emergency Health Services transported 27.7% of the cases to our hospital with the diagnosis of trauma and 72.3% with the diagnosis of non-trauma emergency. Triple system triage was applied to 69.9% of the transported cases; 4.8% were given red, and 43.0% were given green triage codes. The proportion of applicants who met the 32 international emergency parameters determined by the World Health Organization was 35.4%, while 64.6% were not accepted as emergencies according to the same parameters. Moreover, 77.7% of patients admitted with a preliminary diagnosis of trauma and 76.6% of patients admitted with non-trauma diagnoses were discharged.Conclusion: When the need for hospitalization, ES diagnoses, and triage codes were evaluated, it was concluded that most transported cases did not have an emergency medical condition, and prehospital emergency health services were misused. Emergency health service providers should use appropriate triage scales to reduce the density and prevent unnecessary use.

Background: With increasing rates of patient conveyances from nursing homes to emergency departments worldwide, we aim to examine factors causing high rates of conveyances from nursing homes to the emergency department (ED) of an acute tertiary hospital. Methods: This was a prospective study involving presentation of ED attendances from nursing home residents during out-of-hours over a 23-month period from April 2020 to February 2022. Data was collected from a standardized manual form used by the Emergency Department to document nursing home conveyances. Results: A total of 338 pre-conveyance forms were reviewed. The most common reasons for conveyances to ED were neurological symptoms (16%), unstable hemodynamics (12%), fever (11%) and falls (10%). The peak conveyances occurred between 1600 and 1900 h on weekends. Respiratory rate, oxygenation requirements and high National Early Warning Score (NEWS) were significantly associated with increased conveyances to the emergency department. When the components of NEWS were analyzed individually, decision for ambulance conveyance to emergency department was significantly associated with respiratory rate (p <.001), oxygen saturation (p <.001), and the use of oxygen supplementation (p <.005). Conclusions: Unstable hemodynamics and falls were among the leading factors for nursing home conveyances to the emergency department, which highlights the need to implement better fall prevention strategies and standardized parameters monitoring in nursing homes. Future research should focus on outcomes of conveyances and the characteristics of nursing home with higher conveyance rates. This would aid to assess the appropriateness of conveyances and to identify strategies to decrease preventable conveyances. [ABSTRACT FROM AUTHOR]

Introduction: The fourth INTEnsive ambulance-delivered blood pressure Reduction in hyper-ACute stroke Trial (INTERACT4) is a large-scale, multicenter, prospective, randomized, open-label, blinded endpoint assessment trial, initiated in an ambulance in China, aiming at evaluating the effectiveness and safety of prehospital blood pressure (BP) lowering in patients with suspected acute stroke and elevated BP. A prespecified process evaluation is intended to explore the implementation of the trial intervention, provide support to interpret the trial outcomes and put forward suggestions to scale up the intervention in broader settings in the future. Methods: This process evaluation is a mixed-methods design, and follows the Normalization Process Theory (NPT) and the UK Medical Research Council (UK MRC) guidance. Fidelity, reach, acceptability, appropriateness, adoption, sustainability, and relevant contextual factors and mechanisms affecting the implementation of prehospital early intensive BP-lowering treatment will be analyzed. Semi-structured interviews with ambulance staff, ward and emergency department clinicians, and nurses are undertaken to explore perceptions of the intervention, contextual factors, and potential suggestions for future implementation in practice. Data from observational records, surveys, conventional monitoring data, on-site records, and case report forms will be analyzed to understand background care and context. Conclusion: The process evaluation of INTERACT4 will provide insights for the implementation of prehospital early intensive BP-lowering intervention in different health systems and help better explain the trial results for further scale up.

One of the threats that Emergency Medical Services (EMS) personnel regularly face on the field is ambulance collisions and crashes. Ambulance crashes cause death and injury burden on both the EMS personnel and the civilians. In our study we aimed to evaluate the characteristics of ambulance crashes in Ankara, capital province of Türkiye. This retrospective study analyzed 812 ambulance crashes in Ankara, Türkiye, from 01/01/2022 to 31/12/2023 using data from the EMS Command Centre. Crashes were categorized by location, date, driver's gender and education, patient presence, and accident mechanism, revealing significant correlations between crash incidence and factors such as patient absence and urban settings with stationary objects. We found that there is no statistically significant correlation between the gender and the educational status of the driver and the risk of an ambulance crash. Our data analysis also points out that crashes occur involving a stationary object and EMS vehicle are more common than other mechanisms. Additionally, there is statistically significant correlation between the incidence of an ambulance crash and the absence of a patient inside the ambulance. Ambulance crashes in Ankara, Türkiye, frequently involve stationary vehicles on straight roads in urban areas and are more common when no patient is on board. These findings highlight the need for improved training and safety measures for ambulance drivers to prevent such accidents. [ABSTRACT FROM AUTHOR]

The study utilizes a geospatial approach to analyze the risk of motorcycle accidents in Khon Kaen Municipality, Thailand. We focus on identifying high-crash areas involving motorcyclists and investigating factors contributing to the severity of accidents and potential survival rates. The analysis is framed within the "Chain of Survival" framework, specifically focusing on how the location of ambulance stations affects the Emergency Medical Service (EMS) response times. Additionally, we explore various traffic management strategies, with an emphasis on their effectiveness in reducing nighttime accidents. The primary goal of this research is to gain a comprehensive understanding of the spatial distribution of motorcycle accidents and to identify key factors influencing their outcomes. Our findings reveal that motorcycle accidents constitute the highest number of traffic accidents in the area, with a significant proportion occurring in the southwest of Khon Kaen Municipality during late night hours. Given the importance of early intervention within the EMS, we suggest locating EMS stations close to areas with a high incidence of accidents concerning the effective response time, as recommended at two specific points. However, due to limitations in the number of EMS teams available, these recommended points may experience delays in response times, particularly during late-night hours when traffic accidents peak. Ultimately, the insights gained from this study will inform data-driven recommendations aimed at optimizing both emergency response systems and traffic management strategies to enhance road safety in Khon Kaen Municipality.

We present two critical cases of life‐threatening postpartum hemorrhage (PPH) due to amniotic fluid embolism (AFE) complicated by disseminated intravascular coagulopathy (DIC). These cases are the first to show the effectiveness of resuscitative endovascular balloon occlusion of the aorta (REBOA) for patient survival. In Case 1, the patient, experiencing critical conditions with severe PPH and DIC despite conventional treatments, including rapid blood transfusion and fibrinogen concentrate, was air‐transferred to our hospital, where REBOA was promptly employed before hysterectomy was completed. Case 2 involved an ambulance‐transferred patient with massive PPH and DIC despite conventional treatments. Prehospital REBOA was performed to prevent cardiac arrest during transfer, and hysterectomy was performed in the hospital. Given the rapid deterioration associated with AFE, REBOA can serve as a bridge until complete hemostasis to maintain vital signs and control bleeding in patients unresponsive to standard therapies before hemostatic interventions or during transfer.

'Ramping' is a commonly used term in contemporary Australian healthcare. It is also a part of the public and political zeitgeist. However, its precise definition varies among sources. In the published literature, there are distinctions between related terms, such as 'entry overload' and 'Patient Off Stretcher Time Delay'. How ramping is defined and how it came to be defined have significance for policies and procedures relating to the described phenomenon. Through examination of the history of the term, insights are obtained into the underlying issues contributing to ramping and, accordingly, associated possible solutions. [ABSTRACT FROM AUTHOR]

Why you should read this article: • To understand why demand for ambulances has increased in recent years • To reflect on why people experiencing mental health issues often contact emergency services • To learn how mental health professionals working within 999 call centres can help to reduce demand on emergency services. Demand for ambulances has increased significantly in recent years due, for example, to ongoing public health issues and lack of availability of alternative healthcare services. However, as demand increases, so too do ambulance waiting times, partly due to significant pressures on emergency departments (EDs) resulting in handover delays. People experiencing mental health distress who cannot access the care they need often contact ambulance services or present to the ED. Ambulance trusts across the UK are attempting to address this by employing mental health professionals (MHPs) in various capacities. In this article, the authors explore some of the issues related to mental health-related calls to 999 services. The authors then describe a service improvement initiative in Wales which involves MHPs working in 999 call centre clinical support desk services to improve the quality of care delivered to people with mental health issues and reduce demand on ambulance and ED services.

Background: Although unplanned deliveries in ambulances are uncommon, Emergency Medical Services (EMS) providers may encounter this situation before reaching the hospital. This research aims to gather insights from Emergency Medical Technicians (EMTs), midwives, and expectant mothers to examine the causes of giving birth in ambulances and the challenges EMTs, pregnant women, and midwives face during delivery. Methods: A qualitative study was conducted, and 28 EMTs, midwives, and pregnant women who had experience with pre-hospital births in the ambulance were interviewed. Data were analyzed using thematic content analysis. The MAXQDA/10 software was employed for data analysis and code extraction. Results: The analysis of the interviews revealed two main categories: factors that cause delivery in the ambulance and its challenges. The factors include cultural problems, weak management, and inaccessibility to facilities. The challenges consist of fear and anxiety, native culture, and lack of resources. Conclusions: Several approaches should be implemented to reduce the number of births in ambulances and Pre-hospital Emergency Medical Services (PEMS). These include long-term community cultural activities, public education, awareness campaigns, education and follow-up for pregnant women, and improved accessibility to health facilities. Additionally, EMTS need to receive proper education and training for ambulance deliveries. Enhancing ambulance services and supporting EMTs in dealing with litigation claims are also critical.

We present a novel online optimization approach to tackle the ambulance routing problem on a road network, specifically designed to handle uncertainties in travel times, triage levels, required treatment times of victims, and potential changes in victim conditions in post-disaster scenarios. We assume that this information can be learned incrementally online while the ambulances get to the scene. We analyze this problem using the competitive ratio criterion and demonstrate that, when faced with a worst-case instance of this problem, neither deterministic nor randomized online solutions can attain a finite competitive ratio. Subsequently, we present a variety of innovative online heuristics to address this problem which can operate with very low computational running times. We assess the effectiveness of our online solutions by comparing them with each other and with offline solutions derived from complete information. Our analysis involves examining instances from existing literature as well as newly generated large-sized instances. One of our algorithms demonstrates superior performance when compared to the others, achieving experimental competitive ratios that closely approach the optimal ratio of one. [ABSTRACT FROM AUTHOR]

Objective: Following recent changes to the German Narcotics Act, this article examines prehospital analgesia by paramedics using piritramide vs. nalbuphine + paracetamol. Material and methods: Prehospital analgesia administered by paramedics from the Fulda (piritramide) and Gütersloh (nalbuphine + paracetamol) emergency services was compared regarding pain intensity at the beginning and end of the mission, measured using the numeric rating scale (NRS). Additionally, an analysis of the resulting complications was carried out. Results: In this study 2429 administrations of analgesia were evaluated (nalbuphine + paracetamol: 1635, 67.3%, initial NRS: 8.0 ± 1.4, end of NRS: 3.7 ± 2.0; piritramide: 794, 32.7%, initial NRS: 8.5 ± 1.1, end of NRS: 4.5 ± 1.6). Factors influencing NRS change were initial NRS (regression coefficient, RC: 0.7075, 95% confidence interval, CI: 0.6503–0.7647, p < 0.001), treatment with nalbuphine + paracetamol (RC: 0.6048, 95% CI: 0.4396–0.7700, p < 0.001). Treatment with nalbuphine + paracetamol (n = 796 (48.7%)) compared to piritramide (n = 190 (23.9%)) increased the odds of achieving NRS < 4 (odds ratio, OR: 2.712, 95% CI: 2.227–3.303, p < 0.001). Complications occurred in n = 44 (5.5%) with piritramide and in n = 35 (2.1%) with nalbuphine + paracetamol. Risk factors for complications were analgesia with piritramide (OR: 2.699, 95% CI: 1.693–4.301, p < 0.001), female sex (OR: 2.372, 95% CI: 1.396–4.029, p = 0.0014), and age (OR: 1.013, 95% CI: 1.002–1.025, p = 0.0232). Conclusion: Compared with piritramide, prehospital analgesia with nalbuphine + paracetamol has favorable effects in terms of analgesic efficacy and complication rates and should therefore be considered in future recommendations for paramedics.

Introduction Terrorist threats are a worldwide phenomenon. The injuries caused with military weapons or explosives are multiple and unusual for civilian care services. Damage control (DC) training has then become a critical need. In response to the November 2015 attacks, the French authorities launched a national DC training campaign for emergency care personnel. The aim was to describe the implementation of DC training campaign and its perception according to the respondent's profession, DC teaching levels, and the history of terrorist attacks in the last decade of the hospital center's activities. Materials and Methods A survey was distributed to all Casualty Department staff in France. The answers were collected between June 9, 2020 and July 22, 2020. The project was qualified as not involving humans and participation was on voluntary basis. The study is out of the French Jardé law. Results Two-thirds of the 1,525 respondents considered themselves trained in DC (emergency physicians [76.8%], nurse anesthetists [68.1%], and ambulance drivers [65.3%]). Less than half considered their theoretical (41.1%) and practical (44.7%) knowledge excellent or good. More than 95% of the untrained personnel wanted to receive this type of training. Trained personnel were in favor of annual refresher training (95.7%) and training for practical applications (95.1%). Personnel at teaching centers were more frequently trained than personnel at nonteaching centers (respectively 75.3% and 64.3%, P  < .0001) and had applied their knowledge significantly more often (50.1% vs. 43.4%, P  = .038). They often considered their knowledge to be excellent (respectively 50.8% vs. 42.4%, P  = .064). Conclusion The training of emergency personnel in DC is far from being generalized in France. Among the trained personnel, it was often deemed insufficient, in theory and in practice. There was an inequity of training in favor of those in teaching centers. It is therefore essential that training in DC techniques in France be continued, generalized, improved, and standardized throughout the country in order to guarantee an optimal response from the health care systems in the event of new terrorist attacks.

Introduction Military transport can induce whole-body vibrations, and combat almost always involves high impact between lower extremities and the ground. Therefore, robust splinting technology is necessary for lower extremity fractures in these settings. Our team compared a novel one-step spray-on foam splint (FastCast) to the current military standard structured aluminum malleable (SAM) splint. Materials and Methods Ten cadaveric specimens were subjected to complete tibia/fibula osteotomy. Specimens were fitted with custom accelerometer and gyroscope sensors superior and inferior to the fracture line. Each specimen underwent fracture and splinting from a standard of care SAM splint and an experimental FastCast spray foam splint in a randomized order. Each specimen was manually transported to an ambulance and then released from a 1 meter height to simulate impact. The custom sensors recorded accelerations and rotations throughout each event. Repeated-measures Friedman tests were used to assess differences between splint method within each event and between sensors within each splint method. Results During splinting, overall summation of change and difference of change between sensors for accelerations and rotations were greater for SAM splints than FastCast across all axes (P  ≤ 0.03). During transport, the range of acceleration along the linear superior/inferior axis was greater for SAM splint than FastCast (P  = 0.02), as was the range of rotation along the transverse plane (P  < 0.01). On impact, the summation of change observed was greater for SAM splint than FastCast with respect to acceleration and rotation on the posterior/anterior and superior/inferior axes (P  ≤ 0.03), and the cumulative difference between superior and inferior sensors was greater for SAM than FastCast with respect to anterior-axis rotation (P  < 0.05). Conclusion FastCast maintains stabilization of fractured lower extremities during transport and impacts to a significantly greater extent than SAM splints. Therefore, FastCast can potentially reduce the risk of fracture complications following physical stressors associated with combat and extraction. [ABSTRACT FROM AUTHOR]

Emergency Medical Services play a fundamental societal role since they provide pre-hospital care to patients in critical and time-constrained conditions. In this context, the hospital selection decision is vital to respond in a timely, effective and efficient way. By means of simulation experiments, the present study compares the effects of different assignment logics against a set of performance dimensions. To this end, we develop a Discrete Event Simulation model that covers the entire Emergency Medical Service process, from the ambulance transportation to final departure of the patient from the Emergency Department. Results demonstrate that the use of effectiveness-related criteria (e.g. expected waiting time, resource saturation) significantly enhances the overall performance and, at the same time, guarantees higher quality of care. Thus, the study contributes in enhancing hospital selection decisions by supporting decision-makers through a comprehensive decisional model, distancing from prior researches that predominantly considered efficiency-driven criteria (i.e. proximity).

Aims: In tackling rising diabetes‐related emergencies, the need to understand and address emergency service usage by people with type 1 diabetes is vital. This review aimed to quantify current trends in presentations for type 1 diabetes‐related emergencies and identify public health strategies that reduce the frequency of diabetes‐related emergencies and improve glycaemic management. Methods: Medline (OVID), Cochrane and CINAHL were searched for studies published between 2000 and 2023, focusing on people with type 1 diabetes, severe hypoglycaemia and/or diabetic ketoacidosis, and ambulance and/or emergency department usage. There were 1313 papers identified, with 37 publications meeting review criteria. Results: The incidence of type 1 diabetes‐related emergencies varied from 2.4 to 14.6% over one year for hypoglycaemic episodes, and between 0.07 and 11.8 events per 100 person‐years for hyperglycaemic episodes. Notably, our findings revealed that ongoing diabetes education and the integration of diabetes technology, such as continuous glucose monitoring and insulin pump therapy, significantly reduced the incidence of these emergencies. However, socio‐economic disparities posed barriers to accessing these technologies, subsequently shifting the cost to emergency healthcare and highlighting the need for governments to consider subsidising these technologies as part of preventative measures. Conclusions: Improving access to continuous glucose monitoring and insulin pump therapy, in combination with ongoing diabetes education focusing on symptom recognition and early management, will reduce the incidence of diabetes‐related emergencies. Concurrent research assessing emergency healthcare usage patterns during the implementation of such measures is essential to ensure these are cost‐effective. [ABSTRACT FROM AUTHOR]

Aim: To determine whether it was feasible, safe and acceptable for ambulance clinicians to use capillary blood ketone meters for 'high‐risk' diabetic ketoacidosis (DKA) recognition and fluid initiation, to inform the need for a full‐powered, multi‐centre trial. Methods: Adopting a stepped‐wedge controlled design, participants with hyperglycaemia (capillary blood glucose >11.0 mmol/L) or diabetes and unwell were recruited. 'High‐risk' DKA intervention participants (capillary blood ketones ≥3.0 mmol/L) received paramedic‐led fluid therapy. Participant demographic and clinical data were collated from ambulance and hospital care records. Twenty ambulance and Emergency Department clinicians were interviewed to understand their hyperglycaemia and DKA care experiences. Results: In this study, 388 participants were recruited (Control: n = 203; Intervention: n = 185). Most presented with hyperglycaemia, and incidence of type 1 and type 2 diabetes was 18.5% and 74.3%, respectively. Ketone meter use facilitated 'high‐risk' DKA identification (control: 2.5%, n = 5; intervention: 6.5%, n = 12) and was associated with improved hospital pre‐alerting. Ambulance clinicians appeared to have a high index of suspicion for hospital‐diagnosed DKA participants. One third (33.3%; n = 3) of Control and almost half (45.5%; n = 5) of Intervention DKA participants received pre‐hospital fluid therapy. Key interview themes included clinical assessment, ambulance DKA fluid therapy, clinical handovers; decision support tool; hospital DKA management; barriers to hospital DKA care. Conclusions: Ambulance capillary blood ketone meter use was deemed feasible, safe and acceptable. Opportunities for improved clinical decision making, support and safety‐netting, as well as in‐hospital DKA care, were recognised. As participant recruitment was below progression threshold, it is recommended that future‐related research considers alternative trial designs. Clinicaltrials.gov: NCT04940897.

The research team assessed community acceptability of prehospital stroke telemedicine services in rural O‘ahu communities. Tools were developed to evaluate patient-centered goals about implementing ambulance-based telemedicine which aimed to retain appropriate patients in community hospitals and improve thrombolytic treatment times. Using a mixed methods approach, the team surveyed well-appearing adults (ie, able to complete survey and interview) at O‘ahu community events. Participants were asked to complete a short Likert-scale questionnaire (n=263) followed by a semi-structured interview (n=29). Data were summarized by descriptive and inferential statistics. Comparisons between rural and urban groups were made by chi-square analysis and Wilcoxon rank-sum 2-tailed test. Interviews were transcribed, coded, and analyzed using inductive and deductive methods. The findings suggest that use of prehospital telemedicine for specialty care is viewed favorably by both rural and urban respondents. Additionally, most respondents felt comfortable staying at their local hospital if they had access to a specialist by telemedicine. However, mistrust in rural hospitals may be a potential barrier to implementation. Compared to urban respondents, rural respondents were less confident in their local hospital’s resources and capabilities for stroke care. The findings identified a potential misalignment of the project’s goal with some patients’ goal to use emergency medical services (EMS) to bypass rural hospitals for stroke care. Future community outreach efforts are needed to encourage activation of EMS and highlight the advantages of utilizing prehospital telemedicine for accessing specialty care thereby improving treatment times.

To explore paramedics' experiences and perspectives about attending and managing older adults who had fallen. This qualitative, exploratory study used a purposive sample of paramedics in Western Australia. Participants had at least one year of clinical experience. Semi-structured interviews were undertaken. Data were analysed via an inductive thematic approach. Fourteen paramedics were interviewed (Median age: 38 years, n = 5 females). The main theme identified that experiences were positive when attending patients with high-acuity medical problems or injuries following falls because binary decision-making (transport vs non-transport) was appropriate. Themes highlighted that decision-making for low-acuity falls attendances was a complex balance between 1) patient context, 2) risk management, 3) paramedic reactions, and 4) the lack of alternate referral pathways available. Experiences could be stressful and frustrating when attending falls call-outs for older adults with no injuries or medical problems. Participants concurred that when transport to hospital was not required there were no available, alternative pathways to refer onwards for appropriate health or social care. Attending low-acuity call-outs for falls was often frustrating and required complex decision-making, with gaps in services identified. Further exploration of alternative referral pathways for health care for pre-hospital management of adults who fall is required. [ABSTRACT FROM AUTHOR]

Traffic lights are the most commonly used tool to manage urban traffic to reduce congestion and accidents. However, the poor management of traffic lights can result in further problems. Consequently, many studies on traffic light control have been conducted using deep reinforcement learning in the past few years. In this study, we propose a traffic light control method in which a Deep Q-network with fuzzy logic is used to reduce waiting time while enhancing the efficiency of the method. Nevertheless, existing studies using the Deep Q-network may yield suboptimal results because of the reward function, leading to the system favoring straight vehicles, which results in left-turning vehicles waiting too long. Therefore, we modified the reward function to consider the waiting time in each lane. For the experiment, Simulation of Urban Mobility (SUMO) software version 1.18.0 was used for various environments and vehicle types. The results show that, when using the proposed method in a prototype environment, the average total waiting time could be reduced by 18.46% compared with the traffic light control method using a conventional Deep Q-network with fuzzy logic. Additionally, an ambulance prioritization system was implemented that significantly reduced the ambulance waiting time. In summary, the proposed method yielded better results in all environments.

The term 'zero responder' was initially devised in 2010 to describe those passing by or unharmed in a mass casualty incident, who provide life-saving care for injured persons before qualified professionals arrive. This review aims to determine how the literature defines the role of the zero responder and to explore how they can be better integrated into the emergency response. Current definitions of the zero responder in a medical setting were found through a literature search of several databases and online libraries using defined search terms. Additionally, a manual search of citations in included articles was performed to yield more results. In total, 16 papers defining the zero responder were included. These definitions were evaluated, and a revised definition was suggested to clarify the role in a medical setting relating to mass casualty incidents. The role of the zero responder can be facilitated through authority recognition and adequate equipment provision. Familiarisation with the term and role of zero responders among ambulance services is essential for effective collaboration. Further research and clarity on the integration of these two groups is necessary to facilitate effective and safe working between them. [ABSTRACT FROM AUTHOR]

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: The COVID-19 pandemic has significantly stretched global healthcare provisions since its commencement in 2019. From the outset, ambulance services in the UK had to adapt and change their working practices to meet distancing requirements, to increase staff numbers and to ease the effects of staff becoming unavailable for work due to self-isolation and illness. One strategy was moving clinicians from emergency operation centres (EOCs) to working from home. Like many international services, UK ambulance services use paramedics and nurses to undertake telephone and video assessments of patients calling the 999 emergency services line in a model known as virtual care or remote clinical decision making. Virtual care is any interaction between a patient and a clinician or clinicians, occurring remotely via information technologies. Increasing evidence is becoming available to suggest that the pandemic caused harm to the wellbeing of healthcare workers, primarily due to the severe stress of regular exposure to death and human suffering. However, there remains a dearth of literature focusing on the well-being of remote and virtual clinicians, especially those who moved from working in EOCs to working at home during the COVID-19 pandemic. Therefore, this study reports the findings of a qualitative analysis of these effects from the clinician's perspective. The authors hope that the findings from this study will inform the operating, well-being and leadership practices of those delivering such services. Methods: A convenience sample of telephone nurses and paramedics from one UK ambulance service where home working had been implemented were contacted. Fifteen clinicians with recent home-working experience responded to the invitation to participate out of a possible 31 (48%). All participants had previously practised remote assessment from within an EOC. Semi-structured interviews took place via video-conferencing software and were recorded, transcribed and thematically analysed. An inductive approach was taken to generating codes, and both researchers separately read the transcripts before re-reading them, assigning initial themes and determining frequency. Results: Five main themes were discovered, with further associated sub-themes. The main themes were: safety; financial implications; working relationships; home-working environment; and anxiety. Conclusions: Few studies explore remote clinicians' health and well-being. This study identified that home-working clinicians felt that there had been no detrimental impact on their health and well-being because of working from home during the initial phase of the COVID-19 pandemic. While some concerns were raised, these were mitigated through the support that clinicians received at home from family members, as well as from colleagues, some of whom had developed new working relationships. Financial implications appeared to have contributed to some concerns for participants initially, but these had been alleviated quickly despite requiring further exploration of the true financial impact of working from home.

Shock is circulatory insufficiency, inadequate oxygen delivery, and cellular hypoxia. Intravenous fluids are essential for shock management. Despite treatment, patients can face persistent shock with ongoing hypotension, contributing to higher mortality. This analysis aims to quantify hypotensive non-traumatic cases in an Australian ambulance service, determine persistent hypotension prevalence, and assess paramedic-administered intravascular fluids' impact on blood pressure changes. This study is a retrospective analysis of prehospital fluid resuscitation by New South Wales Ambulance paramedics during 2022. Hypotension is defined as a systolic blood pressure of ≤ 90 mmHg, and persistent hypotension is a systolic blood pressure consistently below 90 mmHg across all observations, with a final blood pressure below 90 mmHg. This study aimed to determine the volume of fluid resuscitation at which a plateau in population-level systolic blood pressure response is observed, by calculating the derivative of the fitted logistic regression model. Moreover, this analysis identified the relative contribution of factors influencing the probability of an attempt at intravenous or intraosseous access using machine learning. Among 796,865 attendances, 23,049 (2.9%) involved non-traumatic patients with hypotension. In total 7,388 (32.1%) of the hypotensive cases resulted in persistent hypotension, of which 3,235 (43.8%) received Hartmann's solution and 1,745 (53.9%) received at least 500 ml of fluids but still had hypotension. The model showed that systolic blood pressure tends to stop increasing after 500–600 milliliters of fluid are given. This suggests that, on average, giving more fluid than this may not raise blood pressure further in a prehospital setting, though individual patient needs can differ. The top four factors from the machine learning shows that as initial respiratory rate goes up, the probability of intravascular access rises. Transport times less than 20 min are associated with a smaller chance of access and younger patients are less likely to receive an attempt. Finally, extremes of systolic blood pressure are more likely to receive access attempts. This study found that three percent of non-traumatic attendances have at least one episode of hypotension, and that more than half of these have persistent hypotension. Only 44% of persistently hypotensive received fluids, and half of persistently hypotensive patients stayed hypotensive despite a reasonable volume of prehospital crystalloids. [ABSTRACT FROM AUTHOR]

Ambulance services are increasingly research active and the Rapid Intervention with Glyceryl trinitrate in Hypertensive stroke Trial-2 (RIGHT-2) is the largest United Kingdom (UK) ambulance-based randomized controlled trial in stroke. We explore the complexities and challenges encountered during RIGHT-2. Five hundred and sixteen of 1487 paramedics from eight UK ambulance services serving 54 comprehensive or primary stroke care centers screened and consented 1149 patients presenting within 4 h of FAST-positive stroke and with systolic blood pressure >120 mmHg; participants were randomized to treatment with transdermal glyceryl trinitrate versus sham patch in the ambulance. Working with multiple ambulance services demanded flexibility in the trial protocol to overcome variation in operating procedures to ensure deliverability. Many paramedics are novice researchers, and research concepts and practices are emerging including consent strategies in emergency stroke care. Regional variation in hospital participation and hours/days of operation presented paramedics with additional considerations prior to patient recruitment. The working hours of hospital research staff often do not reflect the 24/7 nature of ambulance work, which challenged deliverability until trial processes became fully embedded. Management of investigational medicinal product between ambulance stations, in-transit when on ambulance vehicles and on handover at hospital, necessitated an in-depth review to maintain accountability. RIGHT-2 demonstrated that although there are significant practical challenges to conducting multicenter ambulance-based research in a time-dependent environment, careful planning and management facilitated delivery. Lessons learned here will help inform the design and conduct of future ambulance-based trials. [ABSTRACT FROM AUTHOR]

COVID-19 has challenged global health care systems and resulted in prehospital delays for time-sensitive emergencies, like stroke and transient ischemic attacks (TIA). However, there are conflicting international reports on the level of effect of the pandemic on ambulance response intervals and emergency call volumes for these conditions. The purpose of this study was to synthesize the international evidence on the effect of COVID-19 on ambulance response intervals and emergency call volume for suspected stroke and TIA. Following a published protocol, we conducted a systematic search of six databases through May 31, 2022. We re-ran this search on April 14, 2023, to check for any new papers. We considered for inclusion peer-reviewed quantitative studies comparing prehospital emergency care for adults with suspected stroke/TIA before and during the COVID-19 pandemic. Two authors screened title/abstract and full text articles. One author carried out data extraction, with a random selection of articles being checked by another author. We calculated overall pooled estimates of ambulance intervals (activation, response, patient care, and total prehospital intervals) and stroke/TIA emergency call volume. Subgroup and sensitivity analyses included location and stroke/TIA diagnosis. Two authors assessed study quality using the appropriate Joanna Briggs Institute tool. We worked with patient and public involvement contributors and clinical and policy stakeholders throughout the review. Of 4,083 studies identified, 52 unique articles met the inclusion criteria. Mean response interval (-1.29 min [-2.19 to -0.38]) and mean total prehospital interval (-6.42 min [-10.60 to -2.25]) were shorter in the pre-COVID-19 period, compared to the COVID-19 period. Furthermore, there was a higher incidence rate of emergency call volume for suspected stroke/TIA per day pre-COVID-19 compared with the COVID-19 period (log IRR = 0.17 [0.02 to 0.33]). Ambulance response interval definitions and terminology varied between regions and countries. Our review indicates that prehospital delays for suspected stroke/TIA increased during the COVID-19 pandemic. Furthermore, emergency call volume for suspected stroke/TIA decreased during this period. In order to minimize delays in future pandemics or other health care emergencies future research may involve understanding the potential reasons for these delays. [ABSTRACT FROM AUTHOR]

Introduction: The COVID-19 pandemic posed significant global challenges to healthcare systems, necessitating rapid education and training adaptations for frontline workers. In Qatar, Hamad Medical Corporation Ambulance Service (HMCAS) has transitioned to distance learning platforms to ensure the continuing professional development of paramedics. The aim of this study was to evaluate the effectiveness of these online learning platforms in meeting the educational needs of HMCAS paramedics in pre-hospital care. Methods: A retrospective observational study design was followed using an online survey. Data were collected using a validated tool focused on accessibility, feasibility, and perception of online learning during the pandemic. Descriptive and inferential statistics (ANOVA) were used to estimate differences in satisfaction scores across themes and analyze the data. Results: The findings revealed that HMCAS paramedics reported high levels of satisfaction (mean 3.93 out of 5) with online learning, citing its ability to meet their educational needs, enhance academic performance, and provide a safe learning environment. However, challenges such as poor internet connectivity, financial constraints, and lack of face-to-face interactions were identified as limitations. ANOVA results indicated that there was higher satisfaction with the online learning program, and that it met their patient care management expectations. Conclusion: This study highlights the potential of online learning to meet the educational needs of paramedics during a global health crisis. The findings suggest that online learning can be an effective and resilient approach to education and training in future public health emergencies with appropriate quality control measures, improved feedback mechanisms, and strategies to enhance interaction and engagement.

The prompt initiation of stroke treatment significantly influences patient outcomes, highlighting the crucial role of prehospital triage. This study aimed to assess the implementation of the 7-Item Japan Urgent Stroke Triage (JUST-7) score by emergency medical services (EMS) in our region and its effect on emergency transportation for suspected stroke patients. Data were collected from patients suspected of having an acute stroke with a Cincinnati Prehospital Stroke Scale (CPSS) score of 1 or more who were transferred by ambulance within 24 h of symptom onset. Two prehospital stroke scales were employed during different periods: period 1 with CPSS alone (January to December 2020) and period 2 with both CPSS and JUST-7 (January 2021 to March 2023). On-scene time data were obtained from the EMS crews, and data regarding the final diagnosis of patients and their outcomes were obtained from the respective hospitals to which the patients were transferred. These data were compared between periods 1 and 2 and between the CPSS and JUST-7. The results revealed that additional evaluation with JUST-7 did not affect ambulance transport time. The CPSS+JUST-7 approach demonstrated higher specificity in identifying stroke and major artery occlusion than with the CPSS alone; however, an appropriate cut-off value needs to be considered. The JUST-7 achieved a diagnostic concordance rate of 35.9% for the most likely stroke type and 64.0% for the first two most likely types. This research emphasizes the potential of JUST-7 as a valuable addition to prehospital stroke diagnosis protocols. Its flexibility in adapting cut-off values based on regional factors and available medical resources optimizes its utility in diverse healthcare settings. The JUST-7 score is a promising tool for improving patient outcomes through prompt and accurate prehospital assessments. [ABSTRACT FROM AUTHOR]

Background: An increasing number of patients receive ambulance care without being conveyed to a definitive care provider. This process has been described as complex, challenging, and lacking in guideline support by EMS clinicians. The use of quality- and outcome measures among non-conveyed patients is an understudied phenomenon. Aim: To identify current quality- and outcome measures for the general population of non-conveyed patients in order to describe major trends and knowledge gaps. Methods: A scoping review of peer-reviewed original articles was conducted to identify quality- and outcome measures for non-conveyance within emergency medical services. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews statement (PRISMA-ScR) was followed. The PROSPERO and OSF database were checked for pending reviews or protocols. PubMed, CINAHL, Scopus, Web of Science and the Cochrane Library database were searched for relevant articles. Searches were performed in November 2023. Results: Thirty-six studies fulfilled the inclusion criteria and were included in the review. Mortality was the most used outcome measure, reported in 24 (67%) of the articles. Emergency department attendance and hospital admission were the following most used outcome measures. Follow-up durations varied substantially between both measures and studies. Mortality rates were found to have the longest follow-up times, with a median follow-up duration a little bit over one week. Conclusions: This scoping review shows that studies report a wide range of quality and outcome measures in the ambulance setting to measure non-conveyance. Reported quality and outcome measures were also heterogeneous with regard to their follow-up timeframe. The variety of approaches to evaluate non-conveyance poses challenges for future research and quality improvement. A more uniform approach to reporting and measuring non-conveyance is needed to enable comparisons between contexts and formal meta-analysis. [ABSTRACT FROM AUTHOR]

The current research on ST elevation myocardial infarction (STEMI) patients has been mostly limited to Door-to-Balloon (D-to-B) time. This study aimed to compare the effects of different hospital admission modes to on the time metrics of patients undergoing primary percutaneous coronary intervention (PPCI). It also examined the effects of these modes on in-hospital mortality and other influencing factors. The goal was to prompt healthcare facilities at all levels, including chest hospitals, the Centers for Disease Control and Prevention (CDC), and communities to take measures to enhance the treatment outcomes for patients with STEMI. A total of 1053 cases of STEMI patients admitted to Tianjin Chest Hospital from December 2016 to December 2023 and successfully underwent PPCI were selected for this study. They were divided into three groups based on the admission modes: the ambulances group (363 cases), the self-presentation group (305 cases), and the transferred group (385 cases). Multivariate logistic regression was used to explore the impact of different modes of hospital admission on the standard-reaching rate of key treatment time metrics. The results showed that the S-to-FMC time of transferred patients (OR = 0.434, 95% CI 0.316–0.596, P < 0.001) and self-presentation patients (OR = 0.489, 95% CI 0.363–0.659, P < 0.001) were more likely to exceed the standard than that of ambulance patients; The cath lab pre-activation time of self-presented patients was also less likely to meet the standard than that of ambulance patients (OR = 0.695, 95% CI 0.499–0.967, P = 0.031); D-to-W time of self-presentation patients was less likely to reach the standard than that of ambulance patients (OR = 0.323, 95% CI 0.234–0.446, P < 0.001);However, the FMC-to-ECG time of self-presentation patients was more likely to reach the standard than that of ambulance patients (OR = 2.601, 95% CI 1.326–5.100, P = 0.005). The Cox proportional hazards model analysis revealed that for ambulance patients, the time spent at each key treatment time point is shorter, leading to lower in-hospital mortality rate (HR0.512, 95% CI 0.302–0.868, P = 0.013) compared to patients admitted by other means. We found that direct arrival of STEMI patients to the PCI hospital via ambulance at the onset of the disease significantly reduces the S-to-FMC time, FMC-to-ECG time, D-to-W time, and catheterization room activation time compared to patients who self-present. This admission mode enhances the likelihood of meeting the benchmark standards for each time metric, consequently enhancing patient outcomes. [ABSTRACT FROM AUTHOR]

Background: Emergency medical services (EMS) are intended to provide people with immediate, effective, and safe access to the healthcare system. The effects of pandemics on emergency medical services (EMS) have not been studied sufficiently. The aim of this paper is to assess the frequency and structure of calls at an ambulance station in Kazakhstan during the period of 2019–2023. Methods: A retrospective analysis was conducted to estimate the incidence of emergency assistance cases from 2019 to 2023. Results: An analysis of the structure and number of ambulance calls before the pandemic, during the pandemic, and post-pandemic period did not reveal significant changes, except for calls in urgency category IV. Patients of urgency category IV handled by an ambulance decreased by 2 and 1.7 times in 2020 and 2021, respectively, which appears to be related to quarantine measures. In 2022 and 2023, category IV calls were 4.7 and 4.5 times higher than in 2019. Conclusions: This study's findings suggest no changes in the dynamics of ambulance calls, except urgency category IV calls. The number of category IV urgent calls decreased significantly during the COVID-19 pandemic and increased in the post-pandemic period. [ABSTRACT FROM AUTHOR]

Objective: Ventilator‐assisted preoxygenation (VAPOX) is a method of preoxygenation and apnoeic ventilation which has been tried in hospital setting. We aimed to describe VAPOX during intubation of critically unwell patients in aeromedical retrieval setting. Methods: Retrospective observational study of VAPOX performed at LifeFlight Retrieval Medicine (LRM) between January 2018 and December 2022 across Queensland, Australia. Demographic and clinical data were recorded. Descriptive statistics and paired Student's t‐tests were used to evaluate the efficacy of VAPOX on oxygen saturation (SpO2). Results: VAPOX was used in 40 patients. Diagnoses included pneumonia (n = 11), COPD (n = 6) and neurological (n = 7). Patients were intubated in hospital (n = 36), in helicopter (n = 2) and ambulance (n = 2). Median VAPOX settings were: positive end‐expiratory pressure 6 (IQR 5–9), pressure support 10 (IQR 10–14) and back up respiratory rate 14 (IQR 11–18). Twelve agitated patients underwent delayed sequence induction with ketamine. There was a statistically significant increase in SpO2 after application of VAPOX (P < 0.001), followed by a slight decrease after intubation (P = 0.006). Mean SpO2 were significantly improved after intubation compared with on arrival of LRM (P = 0.016). Hypotension was present prior to VAPOX (n = 13), during VAPOX (n = 2) and post‐intubation (n = 15). Two patients had cardiac arrest. Three patients were started on VAPOX but subsequently failed. There were no significant oxygen depletion or aspiration events. Conclusion: VAPOX can be considered for pre‐intubation optimisation in the retrieval environment. The incidence of post‐intubation critical hypoxia was low, and hypotension was high. Pre‐intubation respiratory physiology can be optimised by delivering variable pressure supported minute ventilation, achieving a low incidence of critical hypoxia. [ABSTRACT FROM AUTHOR]

Objective: The ambulance service in Victoria, Australia implemented a revised clinical response model (CRM) in 2016 which was designed to increase the diversion of low‐acuity Triple Zero (000) calls to secondary telephone triage and reduce emergency ambulance dispatches. The present study evaluates the influence of the revised CRM on emergency ambulance response times and ED presentations. Methods: A retrospective study of emergency calls for ambulance between 1 January 2015 and 31 December 2018. Ambulance data were linked with ED presentations occurring up to 48 h after contact. Interrupted time series analyses were used to evaluate the impact of the revised CRM. Results: A total of 2 365 529 calls were included. The proportion allocated a Code 1 (time‐critical, lights/sirens) dispatch decreased from 56.6 to 41.0% after implementation of the revised CRM. The proportion of calls not receiving an emergency ambulance increased from 10.4 to 19.6%. Interrupted time series analyses demonstrated an improvement in Code 1 cases attended within 15 min (Key Performance Indicator). However, for patients with out‐of‐hospital cardiac arrest or requiring lights and sirens transport to hospital, there was no improvement in response time performance. By the end of the study period, there was also no difference in the proportion of callers presenting to ED when compared with the estimated proportion assuming the revised CRM had not been implemented. Conclusion: The revised CRM was associated with improved Code 1 response time performance. However, there was no improvement in response times for high acuity patients, and no change in the proportion of callers presenting to ED. [ABSTRACT FROM AUTHOR]

Objective: Preventable transmission of blood‐borne viruses (BBV), including human immunodeficiency virus (HIV), hepatitis C virus (HCV) and hepatitis B virus (HBV), continue in at‐risk populations, including people who use alcohol and drugs (AODs). To our knowledge, no studies have explored the use of ambulance data for surveillance of AOD harms in patients with BBV infections. Methods: We used electronic patient care records from the National Ambulance Surveillance System for people who were attended by an ambulance in Victoria, Australia between July 2015 and July 2016 for AOD‐related harms, and with identified history of a BBV infection. Descriptive and geospatial analyses explored the epidemiological and psychosocial characteristics of patients for these attendances. Results: The present study included 1832 patients with a history of a BBV infection who required an ambulance for AOD‐related harms. Amphetamines were reported in 24.7% of attendances where the patient identified HIV history, and heroin was reported more often for patients with viral hepatitis history (HCV: 19.2%; HBV: 12.7%). Higher proportions of attendances with a viral hepatitis history were observed in patients from the most socially disadvantaged areas. Geospatial analyses revealed higher concentrations of AOD attendances with a BBV history occurring in metropolitan Melbourne. Conclusions: Our study describes the utility of ambulance data to identify a sub‐population of patients with a BBV history and complex medical and social characteristics. Repeat attendances of BBV history patients to paramedics could present an opportunity for ongoing surveillance using ambulance data and possible paramedic intervention, with potential linkage to appropriate BBV services.

The current fallback position for the elderly frail nearing the end of life (less than 12 months to live) is hospitalisation. There is a reluctance to use the term 'terminally ill' for this population, resulting in overtreatment, overdiagnosis and management that is not consistent with the wishes of people. This is the major contributor to the so‐called hospital crisis, including decreased capacity of hospitals, reduced ability to conduct elective surgery, increased attendances at emergency departments and ambulance ramping. The authors recently conducted the largest randomised study, to their knowledge, attempting to inform specialist hospital medical teams about the terminally ill status of their admitted patients. This information did not influence their clinical decisions in any way. The authors discuss the reasons why this may have occurred, such as the current avoidance of discussing death and dying by society and the concentration of healthcare workers on actively managing the acute presenting problem and ignoring the underlying prognosis in the elderly frail. The authors discuss ways of improving the management of the elderly nearing the end of life, such as more detailed goals of care discussions using the concept of shared decision‐making rather than simply completing Advanced Care Decision documents. Empowering people in this way could become the most important driver of people's health care. [ABSTRACT FROM AUTHOR]

This article explores the advancements in blood transfusion practices for resuscitating bleeding patients, which have been influenced by experiences on the battlefield and later adopted in civilian settings. These changes, such as using balanced ratios of blood products and prepositioning blood in emergency departments, have improved outcomes for trauma patients and those with hemorrhagic shock. However, there are still three major changes needed for wider implementation: adopting a walking blood bank, correcting reimbursement practices for prehospital blood transfusion, and ensuring military personnel are trained in transfusion practices. The article also addresses the issue of blood shortages in the United States and suggests implementing a whole blood-based resuscitation strategy as a potential solution. The authors emphasize the importance of military-civilian partnerships and call for policy changes to support the routine use of prehospital blood products and the implementation of the whole blood-based resuscitation strategy in civilian trauma systems.

People often have not received the support they needed during a mental health crisis that triggered an emergency service (911) call. In order to address this gap, an Aotearoa New Zealand Co-Response Team (CRT) was established and studied over 12 months. With co-response, specialist staff from police, ambulance and mental health services jointly attend 911-mental health crises providing simultaneous multidisciplinary input. This study employed qualitative methods to analyze the narratives obtained from 23 service users and family/supporters who experienced co-response. Themes included 'I needed help', 'humanistic engagement' and 'good but not perfect'. Participants liked the co-response model. CRT staff were praised for their kind approach, reassuring communication and practical multi-disciplinary help that differed from prior experiences. Some participants experienced poor follow-up support and some felt intimidated by the CRT police presence, recommending improved pathways and a cautious CRT police approach. [ABSTRACT FROM AUTHOR]

Introduction: The aim of the study was to explore social isolation and loneliness in those who frequently contacted the ambulance service, what factors contributed to this and how unmet needs could be addressed. Methods: Semi‐structured interviews with staff from the ambulance service and service users who were identified as frequently contacting the ambulance service. Service users also completed the UCLA loneliness scale and personal community maps. Data were analysed thematically before triangulation with the UCLA loneliness scale and personal community maps. Results: The final analysis was drawn from 15 staff and seven service user participants. The relationship between social isolation and loneliness and contacting the ambulance service was a contributing, but not the driving, factor in contacting the ambulance service. For service users, we identified three key themes: (1) impact on activities of daily living and loneliness and/or isolation as a result of a health condition; (2) accessing appropriate health and social care services to meet needs; (3) the link between social isolation and/or loneliness and contact with the ambulance service. The analysis of staff data also highlighted three key themes: (1) social isolation and/or loneliness in their role; (2) access to other appropriate health and social care services; (3) the impact of austerity and Covid‐19 on social isolation and/or loneliness. Conclusions: Our research emphasises the complex nature of social isolation and loneliness, including the cyclic nature of poor health and social isolation and loneliness, and how this contributes to contact with the ambulance service. Patient or Public Contribution: The advisory group for the study was supported by a public and patient representative who contributed to the design of the study documentation, data analysis and authorship.

Paediatric supraventricular tachycardia (SVT) is a common arrhythmia of great clinical significance. If not treated promptly, it can cause heart failure and cardiogenic shock. Depending on the patient's condition, SVT treatment involves vagal manoeuvres, pharmacological, or direct current cardioversion. The goal of acute SVT management is to immediately convert SVT to a normal sinus rhythm (NSR) and prevent its recurrence. Adenosine is recommended as the first-line treatment for stable SVT by the European Resuscitation Council (ERC) and American Heart Association (AHA) guidelines, when vagal manoeuvres have proven ineffective. The ERC and AHA guidelines recommend the intravenous route of administration. The intraosseous (IO) administration technique is also possible, but still relatively unknown. The aim of this paper is to describe a 3.5-year-old child with SVT that was converted to NSR following IO administration of adenosine. Successful conversion was achieved after the second attempt with the adenosine dose. In the described case, there was no recurrence of SVT. [ABSTRACT FROM AUTHOR]

During the COVID-19 pandemic, ambulance divert in our EMS system reached critical levels. We hypothesized that eliminating ambulance divert would not be associated with an increase in the average number of daily ambulance arrivals. Our study objective was to quantify the EMS and emergency department (ED) effects of eliminating ambulance divert during the COVID-19 pandemic. Regional hospital divert data were obtained for the 10-county Twin Cities metro from MNTrac, a state-supported online system designed to allow hospitals to indicate their divert status to EMS. ED metrics are reported for a single Level I trauma center and were obtained by a deidentified data pull from our electronic medical record covering the 12 months prior to the elimination of divert (2021) and the 12 months after divert elimination (2022). The decision to eliminate divert occurred in November 2021, based on data available through October, with an implementation date of January 2022. The primary study outcome was to quantify the effect of the elimination of divert on the number of ambulances arriving per day at the study hospital. Regional utilization of ambulance divert increased steadily by 859% from January to October 2021 when 355 individual divert events occurred, totaling 809 h (34 days). There was no significant difference in the number of ambulances that arrived to the study hospital in 2021 (30,774) vs 2022 (30,421) p = 0.15. As compared to 2021, in 2022 there was no significant increase in mean ambulance arrivals per day (84/day vs 83/day, p = 0.08), time to room Emergency Severity Index level 2 (ESI) patients (28 min vs 28 min, p = 0.90), or time to obtain emergent head CT in acute "code stroke" patients (12 min vs 12 min, p = 0.15). Ambulance turnaround interval in the ED did not appreciably increase (16 min vs 17 min, p = 0.15). Elimination of ambulance divert was not associated with increases in the number of mean daily ambulance arrivals or EMS turnaround intervals, delays in ESI 2 patients being placed in beds, or prolonged time to head CT in stroke code patients.

Emergency medical services (EMS) facilitated telemedicine encounters have been proposed as a strategy to reduce transports to hospitals for patients who access the 9-1-1 system. It is unclear which patient impressions are most likely able to be treated in place. It is also unknown if the increased time spent facilitating the telemedicine encounter is offset by the time saved from reducing the need for transport. The objective of this study was to determine the association between the impressions of EMS clinicians of the patients' primary problems and transport avoidance, and to describe the effects of telemedicine encounters on prehospital intervals. This was a retrospective review of EMS records from two commercial EMS agencies in New York and Tennessee. For each EMS call where a telemedicine encounter occurred, a matched pair was identified. Clinicians' impressions were mapped to the corresponding category in the International Classification of Primary Care, 2nd edition (ICPC-2). Incidence and rates of transport avoidance for each category were determined. Prehospital interval was calculated as the difference between the time of ambulance dispatch and back-in-service time. Of the 463 prehospital telemedicine evaluations performed from March 2021 to April 2022, 312 (67%) avoided transports to the hospital. Respiratory calls were most likely to result in transport avoidance (p = 0.018); no other categories had statistically significant transport rates. Four hundred sixty-one (99.6%) had matched pairs identified and were included in the analysis. When compared to the matched pair, telemedicine without transport was associated with a prehospital interval reduction in 68% of the cases with a median reduction of 16 min; this is significantly higher than telemedicine with transport when compared to the matched pair with a median interval increase in 27 min. Regardless of transport status, the prehospital interval was a median of 4 min shorter for telemedicine encounters than non-telemedicine encounters (p = 0.08). In this study, most telemedicine evaluations resulted in ED transport avoidance, particularly for respiratory issues. Telemedicine interventions were associated with a median four-minute decrease in prehospital interval per call. Future research should investigate the long-term effects of telemedicine on patient outcomes. [ABSTRACT FROM AUTHOR]

Ambulance crews play an important role in responding quickly to emergencies and rescuing patients by providing appropriate treatment. Typically, fully equipped emergency vehicles are used to transport ambulance personnel to emergency locations. The ambulance crew cleans, sterilizes, and prepares equipment after each patient transfer with great care. Additionally, they check more than 70 pieces of equipment twice a day using a checklist, which is a tedious, time-consuming, and error-prone task. This study uses computer vision and deep learning techniques to replace the manual checklist process for medical equipment to assist the crew and make the equipment availability check faster and easier. To accomplish this, a dataset containing 2099 images of medical equipment in ambulances was collected and annotated with 3000 labeled instances. An experimental study compared the performance of YOLOv9-c, YOLOv8n, and YOLOv7-tiny. YOLOv8n demonstrated the best performance with a mAP50 of 99.2% and a speed of 3.3 ms total time per image. Therefore, YOLOv8 was selected for the proposed system due to its high accuracy and detection speed, which make it suitable for mobile applications. The presence of an application integrated with computer vision and deep learning technologies in paramedic devices can assist in reviewing the equipment checklist, reducing human errors, speeding up the review process, and alleviating the burden on paramedics in their work.

AbstractThis study addresses the problem of optimizing composition and distribution of an ambulance fleet within an existing emergency medical system. The primary objective is to formulate a strategy aimed at minimizing response times and enhancing the system's responsiveness, particularly to critically ill patients. The optimal spatial distribution of various types of vehicles is proposed using a hierarchical p-median model. The effects of these strategies are evaluated through a detailed computer simulation model. Experimental studies have shown that optimizing station locations contributes more significantly than altering the fleet composition and associated dispatching protocols. In the context of the Slovak Republic, the proportion of high-priority incidents responded to within 8 minutes could be increased by 8.7% in urban areas and 10.5% in rural areas, solely through optimal deployment of currently active ambulances. An additional improvement of nearly 2% could be achieved by introducing 13 patient transport ambulances, optimally distributed throughout the country. [ABSTRACT FROM AUTHOR]

Unidentified patients present a medical information dilemma for all medical departments but can be a major problem in Emergency Departments (EDs). This study aimed to determine the clinical and socio-demographic profile of 'unidentified' patients admitted to the ED with altered consciousness and to define the outcomes of these patients. All ED presentations were analyzed retrospectively for the unidentified patients brought to the hospital by ambulance with altered consciousness. We assessed demographic data, clinical presentation, discharge information, and major clinical outcomes. In this study, 1324 unidentified patients were admitted with altered consciousness to the ED. Of these, 1048 (80.1%) were foreign nationals. In this patient group, the most common diagnoses were; traffic accidents, assault or sharp object injuries, drug addicts, or syncope-epilepsy. In addition, the number of patients who left the hospital without permission or escaped and therefore could not be diagnosed was higher in the foreign nationalities group and constituted approximately one-fifth of the patients (18.9% vs. 5.4%, p:0.001). Of the unidentified patients, 903 (68.2%) were discharged after treatment. 351 (26.5%) patients left the ED unattended. 32 (2.4%) patients were hospitalized. 38 (2.9%) patients died in ED. The majority of the unidentified patients admitted to the ED with altered consciousness were immigrant males. Unidentified patients are a high-need population, most commonly presenting with substance misuse or trauma. Although most of the patients were seeking urgent treatment, more than one-fourth of the patients left the hospital without appropriate treatment and most of these patients were also immigrants. We believe that economic, linguistic, and social disadvantages played an important role in this outcome. [ABSTRACT FROM AUTHOR]

Aim Design Methods Results Conclusions Impact Reporting Method Patient or Public Contribution To explore frontline decision‐making, adaptation, and learning in ambulance care during the evolving COVID‐19 pandemic.Descriptive and interpretative qualitative study.Twenty‐eight registered nurses from the Swedish ambulance services described 56 critical incidents during the COVID‐19 pandemic through free‐text questionnaires. The material was analysed using the Critical Incident Technique and Interpretive Description through the lens of potential for resilient performance.The findings were synthesized into four themes: ‘Navigating uncharted waters under never‐ending pressure’, ‘Balancing on the brink of an abyss’, ‘Sacrificing the few to save the many’ and ‘Bracing for the next wave’. Frontline decision‐making during a pandemic contribute to ethical dilemmas while necessitating difficult prioritizations to adapt and respond to limited resources. Learning was manifested through effective information sharing and the identification of successful adaptations as compared to maladaptations.During pandemics or under other extreme conditions, decisions must be made promptly, even amidst emerging chaos, potentially necessitating the use of untested methods and ad‐hoc solutions due to initial lack of knowledge and guidelines. Within ambulance care, dynamic leadership becomes imperative, combining autonomous frontline decision‐making with support from management. Strengthening ethical competence and fostering ethical discourse may enhance confidence in decision‐making, particularly under ethically challenging circumstances.Performance under extreme conditions can elevate the risk of suboptimal decision‐making and adverse outcomes, with older adults being especially vulnerable. Thus, requiring targeted decision support and interventions. Enhancing patient safety in ambulance care during such conditions demands active participation and governance from management, along with decision support and guidelines. Vertical communication and collaboration between management and frontline professionals are essential to ensure that critical information, guidelines, and resources are effectively disseminated and implemented. Further research is needed into management and leadership in ambulance care, alongside the ethical challenges in frontline decision‐making under extreme conditions.Findings are reported per consolidated criteria for reporting qualitative research (COREQ).No Patient or Public Contribution.

Background: Teamwork in the context of ambulance services exhibits unique characteristics, as this environment involves a small core team that must adapt to a dynamic team structure that involves health care professionals and emergency services. It is essential to acquire a deeper understanding of how ambulance teams operate. Therefore, this study aimed to explore the experiences of ambulance professionals with teamwork and how they were influenced by the implementation of a team training programme. Methods: A qualitative descriptive study was conducted involving ambulance professionals who took part in focus group interviews carried out both before and after the implementation of a team training program across seven ambulance stations within a Norwegian hospital trust. The data were analysed using reflexive thematic analysis based on a deductive-inductive approach. Results: Our analysis revealed 15 subthemes that characterised ambulance professionals' experiences with teamwork and a team training programme, which were organised according to the five main themes of team structure, communication, leadership, situation monitoring, and mutual support. Ambulance professionals' experiences ranged from the significance of team composition and interpersonal and professional relationships to their preferences regarding different communication styles and the necessity of team leaders within the ambulance service. The team training programme raised awareness of teamwork, while the adoption of teamwork tools was influenced by both individual and contextual factors. The Introduction/Identity, Situation, Background, Assessment and Recommendation (ISBAR) communication tool was identified as the most beneficial aspect of the programme due to its ease of use, which led to improvements in the structure and quality of consultations and information handover. Conclusions: This study documented the diverse characteristics and preferences associated with teamwork among ambulance professionals, emphasising the particular importance of proficient partnerships in this context. Participation in a team training programme was perceived as a valuable reminder of the significance of teamwork, thus providing a foundation for the enhancement of communication skills. Trial registration: ClinicalTrials.gov—ID: NCT05244928. [ABSTRACT FROM AUTHOR]

Introduction: Prehospital capabilities are inadequately developed to meet the growing needs for emergency care in most low- and middle-income countries. This study aims to describe the prehospital care received by the road traffic injury (RTI) victims presenting to a level I Trauma Care Center in Central Kerala, India. Methods: This was a hospital-based prospective observational study, which included consecutive victims of RTI attending the emergency department within 24-h of the event. A structured interview schedule was developed for collecting the data on various domains and the patients were followed up for their duration of hospital stay. Results: A total of 920 RTI victims, were included in this study. Two percent (17/920) of first responders had some sort of training in trauma care whereas the rest were untrained. The time taken to get any help at the scene after an RTI was 8 ± 12.9 min (95% confidence interval [CI] 7.16–8.84) and for first medical contact 25 ± 16 min (95% CI 24–26). No attempt at field stabilization occurred in any case. Three percent (26/920) had received some form of prehospital care, like arrest of hemorrhage using a compression bandage and splinting of the fractured limb with a wooden plank. None of the patients received supplemental oxygen, airway management, or cervical spine immobilization at the site of the accident or en route to the hospital. Conclusion: A lack of an organized prehospital care system results in minimal care before hospital admission. Urgent establishment of ambulance services and structured prehospital care tailored to our health-care system is imperative. [ABSTRACT FROM AUTHOR]
