Integrating the Internet of Medical Things (IoMT) in the Hospital system has modified the traditional medical service from a reactive system based on hospitalization and diseases to a preventive and interoperable system based mainly on the interactive data flow between patients and health professionals. Medical data is collected and processed using medically connected objects (MCOs). According to gathered data, the new medical system should be able to sort patient states based on urgent and critical vital signs, and consequently, priorities are defined. In this paper, we focus on managing priority in hospital emergencies to adapt dynamic operations and interactions with different stakeholders according to the changes in their execution context. Indeed, based on data sensed from MCOs implemented in ambulances, emergency rooms might be prepared to receive injured persons like victims of road accidents or other incidents. Therefore, we design a context-aware monitoring framework for injured people based on gathered medical data to manage priorities. [ABSTRACT FROM AUTHOR]

Background: The transport of patients from one location to another is a fundamental part of emergency medical services. However, little interest has been shown in the actual driving of the ambulance. Therefore, this review aimed to investigate how the driving of the ambulance affects the patient and the medical care provided in an emergency medical situation.Methods: A systematic integrative review using both quantitative and qualitative designs based on 17 scientific papers published between 2011 and 2020 was conducted.Results: Ambulance driving, both the actual speed, driving pattern, navigation, and communication between the driver and the patient, influenced both the patient's medical condition and the possibility of providing adequate care during the transport. The driving itself had an impact on prehospital time spent on the road, safety, comfort, and medical issues. The driver's health and ability to manage stress caused by traffic, time pressure, sirens, and disturbing moments also significantly influenced ambulance transport safety.Conclusions: The driving of the ambulance had a potential effect on patient health, wellbeing, and safety. Therefore, driving should be considered an essential part of the medical care offered within emergency medical services, requiring specific skills and competence in both medicine, stress management, and risk approaches in addition to the technical skills of driving a vehicle. Further studies on the driving, environmental, and safety aspects of being transported in an ambulance are needed from a patient's perspective. [ABSTRACT FROM AUTHOR]

Background: Medicine is facing a global shortage of nurses, including those with postgraduate education. One suggested educational method for undergraduate and postgraduate education, such as specialist ambulance nurse education, is simulation-based education (SBE). The implementation of SBE is motivated, in part, by the desire to attract and retain students, but also to contribute to student learning. Consequently, the use of SBE is increasing in specialist ambulance nurse education. The aim of this study was to explore how specialist ambulance nursing students experience SBE. Methods: This qualitative survey study involved the collection of study data using a purposefully designed, paper-based survey comprising five open-ended questions that required participant free-text answers. The answers were analysed using inductive content analysis and searching for descriptions of the participants' experiences. The survey was presented to 35 specialist ambulance nursing students. Results: The results are presented in two themes: SBE as learning and SBE as an educational method. Participating in SBE during the programme provides students with a realistic understanding of their future profession and its expected demands. The learning experience disregards prior work experience in ambulance services. Conclusions: Based on the findings, conclusions are that SBE is an appreciated educational method among nursing students, regardless of their prior experience in the field of prehospital care. To some extent, this differs from previous research findings related to this subject. Furthermore, SBE contributes to the provision of field work insights, preparing the ambulance nurse specialist students. [ABSTRACT FROM AUTHOR]

• Nigeria seeks to meet international standards for Out of Hospital Emergency Care (OHEC). • We highlighted the standard of service in public (government) and privately owned OHEC services. • While improvements have been made, poor-quality prehospital logistics, coordination, and oversight are inhibiting the growth and development of Nigerian OHEC. • This review highlights the importance and challenges of OHEC in Nigeria and outlines recommendations that may apply to other African countries with similar socioeconomic challenges. Out of Hospital Emergency Care (OHEC) in Nigeria, the most populous country with the highest GDP in Africa, is considered inadequate. A better understanding of the current state of OHEC is essential to address the country's unique challenges and offer potential solutions. This paper sought to identify gaps, barriers, and facilitators in implementing an OHEC model in Nigeria and provide recommendations for improvement. We searched MEDLINE (PubMed), Embase (OVID), CINAHL (EBSCO), and Google Scholar, using combinations of "emergency medical care" ('FRC,' 'PHC,' and 'EMS') OR prehospital care OR emergency training' AND 'Nigeria.' We included papers that described OHEC in Nigeria and were published in English. Of the initial 73 papers, those that met our inclusion criteria and those obtained after examination of reference lists comprised the 20 papers that contributed to our final review. Two authors independently reviewed all the papers, extracted data relevant to our objectives and performed a content analysis. All authors reviewed, discussed, and refined the proposed recommendations. For OHEC to meet the needs of Nigerians and achieve international standards, the following challenges need to be addressed: harmful cultural practices, inadequate training of citizens in the provision of first aid or of professionals that provide prehospital care, lack of proper infrastructure, poor communication, absent policy, and poor funding. Based on the available literature, this paper proposes key recommendations to improve OHEC with the hope of improving the standards of living. The federal government should provide general oversight, but this will require political will on the part of the country's leadership and the provision of adequate funding. [ABSTRACT FROM AUTHOR]

The COVID-19 pandemic led to massively increased emergency medical services (EMS) activity. The need to decontaminate emergency vehicles after conveying a suspected or confirmed patient to the hospital represented a critical step, slowing the activities and impacting the number of available ambulances. This brief paper analyzes the flow of EMS processes according to the Lean Thinking management approach, which focuses on reducing waste in a production cycle. The different steps of the whole process (arrival to the Emergency Department, handover phase, decontamination, return to service, and the required transfers) and a series of strategies are discussed. The organization (centralized or delocalized), number, and location of the decontamination centers impact transfers and waiting times and, consequently, the availability of ambulances. Optimizing these processes may lead to a global performance improvement, reducing transfers and time, with greater availability of emergency vehicles. [ABSTRACT FROM AUTHOR]

Objective: Paramedicine has evolved in ways that may outpace the science informing these changes. Examining the scholarly pursuits of paramedicine may provide insights into the historical academic focus, which may inform future endeavors and evolution of paramedicine. The objective of this study was to explore the existing discourse in paramedicine research to reflect on the academic pursuits of this community. Methods: We searched Medline, Embase, CINAHL, Google Scholar and Web of Science from January, 2006 to April, 2019. We further refined the yield using a ranking formula that prioritized journals most relevant to paramedicine, then sampled randomly in two-year clusters for full text review. We extracted literature type, study topic and context, then used elements of qualitative content, thematic, and discourse analysis to further describe the sample. Results: The initial search yielded 99,124 citations, leaving 54,638 after removing duplicates and 7084 relevant articles from nine journals after ranking. Subsequently, 2058 articles were included for topic categorization, and 241 papers were included for full text analysis after random sampling. Overall, this literature reveals: 1) a relatively narrow topic focus, given the majority of research has concentrated on general operational activities and specific clinical conditions and interventions (e.g., resuscitation, airway management, etc.); 2) a limited methodological (and possibly philosophical) focus, given that most were observational studies (e.g., cohort, case control, and case series) or editorial/commentary; 3) a variety of observed trajectories of academic attention, indicating where the evolution of paramedicine is evident, areas where scope of practice is uncertain, and areas that aim to improve skills historically considered core to paramedic clinical practice. Conclusions: Included articles suggest a relatively narrow topic focus, a limited methodological focus, and observed trajectories of academic attention indicating where research pursuits and priorities are shifting. We have highlighted that the academic focus may require an alignment with aspirational and direction setting documents aimed at developing paramedicine. This review may be a snapshot of scholarly activity that reflects a young medically directed profession and systems focusing on a few high acuity conditions, with aspirations of professional autonomy contributing to the health and social well-being of communities.

Background: Early pre-hospital initiation of blood pressure (BP) lowering could improve outcomes for patients with acute stroke, by reducing hematoma expansion in intracerebral hemorrhage (ICH), and time to reperfusion treatment and risk of intracranial hemorrhage in ischemic stroke (IS). We present the design of the fourth INTEnsive ambulance-delivered blood pressure Reduction in hyper-ACute stroke Trial (INTERACT4).Methods: A multi-center, ambulance-delivered, prospective, randomized, open-label, blinded endpoint (PROBE) assessed trial of pre-hospital BP lowering in 3116 hypertensive patients with suspected acute stroke at 50+ sites in China. Patients are randomized through a mobile phone digital system to intensive BP lowering to a target systolic BP of < 140 mmHg within 30 min, or guideline-recommended BP management according to local protocols. After the collection of in-hospital clinical and management data and 7-day outcomes, trained blinded assessors conduct telephone or face-to-face assessments of physical function and health-related quality of life in participants at 90 days. The primary outcome is the physical function on the modified Rankin scale at 90 days, analyzed as an ordinal outcome with 7 categories. The sample size was estimated to provide 90% power (α = 0.05) to detect a 22% reduction in the odds of a worse functional outcome using ordinal logistic regression.Discussion: INTERACT4 is a pragmatic clinical trial to provide reliable evidence on the effectiveness and safety of ambulance-delivered hyperacute BP lowering in patients with suspected acute stroke.Trial Registration: ClinicalTrials.gov NCT03790800. Registered on 2 January 2019; Chinese Trial Registry ChiCTR1900020534. Registered on 7 January 2019. All items can be found in this protocol paper. [ABSTRACT FROM AUTHOR]

Background: Internationally increasing demand for emergency care is driving innovation within emergency services. The Alternative Pre-Hospital Pathway (APP) Team is one such Community Emergency Medicine (CEM) initiative developed in Cork, Ireland to target low acuity emergency calls. In this paper the inception of the APP Team is described, and an observational descriptive analysis of the APP Team's service data presented for the first 12 months of operation. The aim of this study is to describe and analyse the APP team service.Methods: The APP Team, consisting of a Specialist Registrar (SpR) in Emergency Medicine (EM) and an Emergency Medical Technician (EMT) based in Cork, covers a mixed urban and rural population of approximately 300,000 people located within a 40-min drive time of Cork University Hospital. The team are dispatched to low acuity 112/999 calls, aiming to provide definitive care or referring patients to the appropriate community or specialist service. A retrospective analysis was performed of the team's first 12 months of operation using the prospectively maintained service database.Results: Two thousand and one patients were attended to with a 67.8% non-conveyance rate. The median age was 62 years, with 33.0% of patients aged over 75 years. For patients over 75 years, the non-conveyance rate was 62.0%. The average number of patients treated per shift was 7. Medical complaints (319), falls (194), drug and alcohol related presentations (193), urological (131), and respiratory complaints (119) were the most common presentations.Conclusion: Increased demand for emergency care and an aging population is necessitating a re-design of traditional models of emergency care delivery. We describe the Alternative Pre-Hospital Pathway service, delivered by an EMT and an Emergency Medicine SpR responding to low acuity calls. This service achieved a 68% non-conveyance rate; our data demonstrates that a community emergency medicine outreach team in collaboration with the National Ambulance Service offering Alternative Pre-Hospital Pathways is an effective model for reducing conveyances to hospital.

• First study to examine paramedic psychological injury through EMS data linkage. • Fatality and cardiac arrest cases increase the odds of psychological injury. • Lower patient age is associated with paramedic psychological injury. • Findings may help facilitate the provision of early interventions to those at risk. Introduction : In comparison to the general population and other emergency services workers, paramedics experience high rates of work-related psychological injury. However, there is limited understanding of the case and practitioner-related factors that increase the risk of psychological injury among these workers. This paper aims to identify case and practitioner-related factors associated with paramedic work-related psychological injury in Victoria, Australia, through data linkage. Methods : Data linkage of 7,223 paramedic injury reports with electronic patient care records, and paramedic demographic data from the single state-wide ambulance service in Victoria, Australia – Ambulance Victoria. Injuries reported between 1 January 2015 and 30 June 2020 were included. Factors associated with paramedic psychological injury were assessed using multivariable logistic regression analysis. Results : A total of 4,641 (64%) injury reports were successfully linked, of which, 244 (5%) were psychological injuries. Shift hours between 0401 and 0800 (AOR 1.83; 95%CI: 1.12–2.97), cardiac arrest or deceased patient attendances (AOR 2.15; 95%CI: 1.06–4.34), hospital or medical center case locations (AOR 2.44; 95%CI: 1.22–4.91), and Priority 0 (AOR 2.27; 95%CI: 1.26–4.09), Priority 2 (AOR 1.56; 95%CI: 1.04–2.33), and Priority 3 (AOR 1.95; 95%CI: 1.15–3.32) dispatch codes were associated with increased odds of psychological injury. Increasing patient age (AOR 0.98; 95%CI: 0.97–0.99), and the absence of other emergency services on scene (AOR 0.50; 95%CI: 0.34–0.72) were associated with decreased odds of paramedic psychological injury. Conclusions: This is the first study to collectively examine and identify EMS case and practitioner-related characteristics associated with paramedic psychological injury through data linkage of EMS agency-level data sources. Practical application: The findings of this study highlight the dispatch case characteristics that may increase the risk of a paramedic sustaining a work-related psychological injury, and consequently facilitate the early identification, intervention, and support of the individuals most at risk.

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.

Introduction: Various early warning score tools have been developed to identify clinical deterioration in patients. This study assessed the predictive capacity of the National Early Warning Score 2 (NEWS-2) in the prehospital setting to predict death within 24 hours and 30-day intensive care unit admission. Methods: A single-center observational retrospective study was conducted in the emergency medical services (EMS) of King Abdulaziz Medical City, Riyadh, Saudi Arabia. We included adult patients (> 18 years) who attended the emergency medical service. The primary outcome was 24-hour death and 30-day intensive care unit admission. Sensitivity, specificity, and negative/positive predictive values (NPV/PPV) were determined. Results: The study comprised 1,343 eligible patients. NEWS-2 exhibited a sensitivity of 20% and a specificity of 80% for predicting 24-hour death and a sensitivity of 10% and a specificity of 80% for predicting 30-day intensive care unit admission. The area under the curve for predicting death was 0.529, and for intensive care unit admission was 0.456. Conclusion: Our study underscores the limited utility of NEWS-2 as a predictor of 24-hour death and 30-day intensive care unit admission in adult patients utilizing the emergency medical service. Further extensive studies are warranted to corroborate this study's findings. [ABSTRACT FROM AUTHOR]

Background: Climate change impacts contemporary health and has the potential to further impact health in the future. This paper investigates ambulance dispatch-health relationships for three major cities in the UK: Birmingham; Glasgow; and London, which have distinct climates. The role of future climate on total ambulance dispatches and specific dispatches associated with breathing difficulties and assaults are investigated. Methods: A Distributed Lag Non-Linear modelling (DLNM) approach was used to model and compare relative risk (RR) across the temperature range for each city. Input data were daily mean temperature for each city and ambulance dispatches. Initial testing indicated that little variation in outcome occurred if maximum and minimum weekly temperature was averaged instead of using the daily means. The models for each city are used to make projections of future risk, attributable number (AN), and attributable fraction (AF). The temperature projections were from the UK Climate Projections 2018 (UKCP18) using the RCP8.5 high emissions scenario. Results: The relationships between temperature and ambulance dispatches were all non-linear, with different relationships for the same variables shown in the three cities. Glasgow showed a smaller and least significant increase in risk at high temperatures (95th percentile), whereas all cities showed significant increases in risk at low temperatures (5th percentile). Under RCP8.5, by 2060, RR is projected to increase in London and Birmingham, and to decrease in Glasgow. As such, the number of daily dispatches attributed to temperature increases by 11 per day in London, 2 in Birmingham, and decreases by 1 in Glasgow by 2060, assuming no changes in city population or demographics. Conclusion: This paper demonstrates that relationships between health and ambient temperatures within three cities in the UK are different. It also shows that under RCP8.5 projections, for a constant population, ambulance dispatches in London and Birmingham will likely increase, but for Glasgow, they will decrease. These findings can contribute to developing demand forecasts for ambulance usage based on meteorological and climatological forecasts.

In this paper, an analytic review of the recent methodologies tackling the problem of dynamic allocation of ambulances was carried out. Considering that state-of-the-art is moving to deal with more extensive and dynamic problems to address in a better way real-life instances, this research looks to identify the evolution and recent applications of this kind of problem once the basic models are explored. This extensive review allowed us to identify the most recent developments in this problem and the most critical gaps to be addressed. In this sense, it is essential to point out that the dynamic location of emergency medical services (EMS) is nowadays a relevant topic considering its impact on the healthcare system outcomes. Issues related to forecasting, simulation, heterogeneous fleets, robustness, and solution speed for real-life problems, stand out in the identified gaps. Applications of machine learning the deployment challenges during epidemic outbreaks such as SARS and COVID-19 were also explored. At the same time, a proposed notation tries to tackle the fact that the word problem in this kind of work refers to a model on many occasions. The proposed notation eases the comparison between the different model proposals found in the literature. [ABSTRACT FROM AUTHOR]

Background: In pre-hospital setting, ambulance provides emergency care and means of transport to arrive at appropriate health centers are as vital as in-hospital care, especially, in developing countries. Accordingly, Ethiopia has made several efforts to improve accessibility of ambulances services in prehospital care system that improves the quality of basic emergency care. Yet, being a recent phenomenon in Ethiopia, empirical studies are inadequate with regard to the practice and determinants of ambulance service utilization in pre-hospital settings. Hence, this study aimed to assess the ambulance service utilization and its determinants among patients admitted to the Emergency Departments (EDs) within the context of pre-hospital care system in public hospitals of Jimma City. Method: A cross-sectional study design was used to capture quantitative data in the study area from June to July 2022. A systematic sampling technique was used to select 451 participants. Interviewer-administered questionnaire was used to collect data. Data analysis was done using SPSS version 26.0; descriptive and logistic regressions were done, where statistical significance was determined at p < 0.05. Results: Ambulance service was rendered to bring about 39.5% (of total sample, 451) patients to hospitals. The distribution of service by severity of illnesses was 48.7% among high, and 39.4% among moderately acute cases. The major determinants of ambulance service utilization were: service time (with AOR, 0.35, 95%CI, 0.2-0.6 for those admitted to ED in the morning, and AOR, 2.36, 95%CI, 1.3-4.4 for those at night); referral source (with AOR, 0.2, 95%CI, 0.1-0.4 among the self-referrals); mental status (with AOR, 1.9, 95%CI, 1-3.5 where change in the level of consciousness is observed); first responder (AOR, 6.3 95%CI, 1.5-26 where first responders were the police, and AOR, 3.4, 95%C1, 1.7-6.6 in case of bystanders); distance to hospital (with AOR,0.37, 95%CI, 0.2-0.7 among the patients within ≤15km radius); and prior experience in ambulance use (with AOR, 4.1,95%CI, 2.4-7). Conclusion: Although the utilization of ambulance in pre-hospital settings was, generally, good in Jimma City; lower levels of service use among patients in more acute health conditions is problematic. Community-based emergency care should be enhanced to improve the knowledge and use of ambulance services. [ABSTRACT FROM AUTHOR]

Introduction: Ambulance service clinical placements are fundamental to paramedicine student education, but the quality and safety of these placements can be highly variable. Inspired by positive results from a nursing facilitator model, this study reports on a collaboration between an Australian university and ambulance service that introduced a paramedic clinical facilitator for undergraduate paramedic students during their ambulance clinical placements. This article describes the experiences of a clinical facilitator model for paramedicine students and their preceptors during the study period. Methods: This study follows an exploratory qualitative research methodology. After implementation of the paramedic clinical facilitator model, two focus groups with paramedicine student participants and two semi-structured interviews with their paramedic preceptors were conducted. Intimate observations were recorded in a reflexive logbook by the facilitator, which was kept for data analysis. Purposive sampling was used to recruit participants, and thematic analysis was used to code data and conceptualise themes. Results: Three broad overarching themes were conceptualised from the data: 1) increased educational opportunities, 2) improved clinical placement management and 3) greater student support and welfare. Both paramedicine students and paramedic preceptors felt that the paramedic clinical facilitator model improved the quality of ambulance clinical placements for undergraduate paramedicine students. Conclusion: This study suggests that a paramedic clinical facilitator model improved the safety and quality of ambulance clinical placement experience for paramedicine students and preceptors. Universities and ambulance services could consider implementing a paramedic facilitator model for ambulance clinical placements in their local contexts. [ABSTRACT FROM AUTHOR]

Many specialists say that the factorial experiment if used properly may bring remarkable results in the practical experiments in the field of motor vehicles. In order to prove these claims, with this paper we will present some theoretical considerations regarding the mathematical model used, but also the practical research carried out to obtain some objective functions such as the average fuel consumption in l/100km. In the context of the research, we present some examples of calculation regarding the actual mathematical modelling as well as, the manner in which one can reach the real values of the objective functions. During the practical research, the influence of disturbing factors suchs as temperature, air presure and humidity, wind speed and vehicle speed, wich can substantially influence the fuel consumption of road vehicle, was taken into account. In the end, some conclusions and directions regarding the research of the modelling are presented.

Background: Prolonged prehospital time is a major global problem in the emergency medical system (EMS). Although factors related to prolonged on-scene times (OSTs) have been reported in patients with trauma and critical medical conditions, those in patients with minor diseases or injuries remain unclear. We examined factors associated with prolonged OSTs in patients with minor diseases or injuries. Methods: This population-based observational study used the ambulance transportation and request call record databases of the Higashihiroshima Fire Department, Japan, between January 1, 2016, and December 31, 2022. The participants were patients with minor diseases or injuries during the study period. We performed a multivariable logistic regression analysis with robust error variance to examine the association between patient age, sex, severity, accident type, date and time of ambulance call, and the coronavirus disease 2019 (COVID-19) pandemic with prolonged OSTs. Prolonged OST was defined as ≥ 30 min from the ambulance arrival at the scene to departure. Results: Of the 60,309 people transported by ambulance during the study period, 20,069 with minor diseases or injuries were included in the analysis. A total of 1,241 patients (6.2%) experienced prolonged OSTs. Fire accidents (adjusted odds ratio [aOR]: 7.77, 95% confidence interval [CI]: 3.82–15.79), natural disasters (aOR: 28.52, 95% CI: 2.09–389.76), motor vehicle accidents (aOR: 1.63, 95% CI: 1.30–2.06), assaults (aOR: 2.91, 95% CI: 1.86–4.53), self-injuries (aOR: 5.60, 95% CI: 3.37–9.32), number of hospital inquiries ≥ 4 (aOR: 77.34, 95% CI: 53.55–111.69), and the COVID-19 pandemic (aOR: 2.01, 95% CI: 1.62–2.50) were associated with prolonged OSTs. Moreover, older and female patients had prolonged OSTs (aOR: 1.18, 95% CI: 1.01–1.36 and aOR: 1.12, 95% CI: 1.08–1.18, respectively). Conclusions: Older age, female sex, fire accidents, natural disasters, motor vehicle accidents, assaults, self-injuries, number of hospital inquiries ≥ 4, and the COVID-19 pandemic influenced prolonged OSTs among patients with minor diseases or injuries. To improve community EMS, we should reconsider how to intervene with potentially modifiable factors, such as EMS personnel performance, the impact of the presence of allied services, hospital patient acceptance systems, and cooperation between general emergency and psychiatric hospitals.

Abstract Background Medicine is facing a global shortage of nurses, including those with postgraduate education. One suggested educational method for undergraduate and postgraduate education, such as specialist ambulance nurse education, is simulation-based education (SBE). The implementation of SBE is motivated, in part, by the desire to attract and retain students, but also to contribute to student learning. Consequently, the use of SBE is increasing in specialist ambulance nurse education. The aim of this study was to explore how specialist ambulance nursing students experience SBE. Methods This qualitative survey study involved the collection of study data using a purposefully designed, paper-based survey comprising five open-ended questions that required participant free-text answers. The answers were analysed using inductive content analysis and searching for descriptions of the participants’ experiences. The survey was presented to 35 specialist ambulance nursing students. Results The results are presented in two themes: SBE as learning and SBE as an educational method. Participating in SBE during the programme provides students with a realistic understanding of their future profession and its expected demands. The learning experience disregards prior work experience in ambulance services. Conclusions Based on the findings, conclusions are that SBE is an appreciated educational method among nursing students, regardless of their prior experience in the field of prehospital care. To some extent, this differs from previous research findings related to this subject. Furthermore, SBE contributes to the provision of field work insights, preparing the ambulance nurse specialist students.

Background: Patients dead before arrival of the ambulance or before arrival at hospital may be in- or excluded in mortality analyses, making comparison of mortality difficult. Often only physicians are allowed to declare death, thereby impeding uniform registration of prehospital death. Many studies do not report detailed definitions of prehospital mortality. Our aim was to define criteria to identify and categorize prehospital patients' vital status, and to estimate the proportion of these groups, primarily the proportion of patients dead on ambulance arrival. Methods: Prehospital medical records review for patients receiving an ambulance in the North Denmark Region from 2019 to 2021 and registered dead on the same or the following day. We defined three vital status categories: (1) Dead on Ambulance Arrival (DOAA), (2) Out-of-Hospital Cardiac Arrest (OHCA) divided into OHCA Basic Life Support (OHCA BLS) and OHCA Advanced treatment, and 3) Alive on Ambulance Arrival. Results: Among 3 174 dead patients, DOAA constituted 28.8%, OHCA BLS 13.4%, OHCA Advanced treatment 31.3%, and Alive on Ambulance Arrival 26.6%. Conclusion: We defined exhaustive and mutually exclusive criteria to define vital status, DOAA, OHCA, and Alive on Ambulance Arrival based on prehospital medical records. More than one out of four patients receiving an ambulance and registered dead on the same or the following day were dead already at ambulance arrival. Adding OHCA BLS where resuscitation was terminated without defibrillation or other treatment, increased the proportion of patients dead on ambulance arrival to 42%. We recommend reporting similar categories of vital status to improve valid comparisons of prehospital mortality rates. [ABSTRACT FROM AUTHOR]

Background: Patients presenting to the ambulance services with cardiovascular complaints are common, and as such, represent a notable proportion of paramedic clinical practice. Numerous texts refer to a system-based approach to cardiovascular assessment, however the application by paramedics is scarcely researched. As such, this article aims to quantify paramedic confidence levels regarding an examination of a patient with a cardiovascular complaint. Methods: An online cross-sectional survey was conducted, recruiting paramedics from one ambulance trust within the United Kingdom and analysing their confidence levels of assessing a patient with a cardiovascular complaint. Paramedics were recruited using purposive sampling and asked to complete an online questionnaire exploring their confidence levels among cardiovascular assessments, which were subsequently quantified to summarise confidence levels expressed by these respondents. Results: A total of 331 responses across one ambulance service were received in April 2021. Of these, 90.3% (299/331) reported a high level of confidence with the general cardiovascular assessment. Throughout all individual elements of assessment, over 50% of respondents indicated they feel confident with the examination, except when assessing heaves and thrills where 56.2% (185/329) and 55.1% (182/330) of respondents disagreed with feeling confident, respectively. A strong correlation was seen throughout the results between confidence levels and the reported occurrence of each type of assessment, which was demonstrated using Spearman's rank-order correlation. Conclusions: High confidence levels for a cardiovascular examination were reported among the respondents of this survey. Paramedics have shown good confidence among all areas of a cardiovascular assessment, except with palpating the chest for heaves and thrills. There is an evident link between reported confidence levels and how often these assessments are completed, however there is still room for additional training and research within this area.

Background and Importance: The COVID-19 pandemic affected the utilization of health care services and posed organizational challenges. While many previous studies focused on the misuse of pre-hospital EMS for low-urgency health problems, the pandemic has put more emphasis on the avoidance of medically necessary calls. Objective: To compare the utilization of pre-hospital emergency medical services before and after specific pandemic periods. Design, setting and participants: This was a retrospective, descriptive analysis of routine data from 26 dispatch centers in Bavaria, Germany. Outcomes measure and analysis: We investigated the number of emergencies per 100,000 population, as well as the relative change in the emergency rates and transport rates in 2020, compared to the two previous years. Boxplots showed the distributions across the Bavarian districts per calendar week. The mean rates and standard deviations as well as the relative changes were presented for the specific periods. A paired samples t-test was used to compare the rates. Main results: Compared to the average of the two previous years, the emergency rates in 2020 were lower in 35 out of 52 calendar weeks. The strongest reductions were observed during the first wave, where the average emergency rate declined by 12.9% (SD 6.8, p < 0.001). There was no statistically significant difference in the overall emergency rate during the summer holidays. Lower transport rates were observed throughout the year, especially during the first wave. Conclusions: Utilization of pre-hospital emergency medical services decreased in 2020, especially during the periods with strict measures. This could be due to the lower morbidity from the behavioral changes during the pandemic, but also to the avoidance of medical services for both less urgent and severe conditions. While a reduction in unnecessary care would be beneficial, patients must be encouraged to seek necessary urgent care, even during a pandemic. [ABSTRACT FROM AUTHOR]

To investigate the current state of emergency vehicle management within sports medicine and athletic hospitals, with a focus on hospitals located in Zhejiang Province. This study aims to provide valuable insights and recommendations for enhancing the management of emergency vehicles in the context of sports medicine. Methods: A convenience sampling approach was employed, involving surveys conducted with nurses from a total of 40 sports medicine and athletic hospitals located in 15 cities across Zhejiang Province during the period from April to May 2022. Results: The findings obtained through the questionnaire survey revealed noteworthy aspects. Specifically, 15.89% of the surveyed hospital departments lacked a dedicated pharmacist responsible for regular quality checks of emergency drugs. Furthermore, 55.14% of the respondents expressed concerns about the athlete nurses' level of knowledge regarding rescue drugs and related items. Alarmingly, the study found that 100% of the departments relied solely on manual inventory management for emergency drugs and items, with only 39.39% of them implementing partial information management systems, leading to varying degrees of inventory discrepancies. Conclusion: The study highlights certain shortcomings in the supervision and management systems related to emergency medicines and equipment within sports medicine and athletic hospitals. Additionally, personnel management practices appear to be lacking in some athletic hospitals. [ABSTRACT FROM AUTHOR]

Abstract Objective Paramedicine has evolved in ways that may outpace the science informing these changes. Examining the scholarly pursuits of paramedicine may provide insights into the historical academic focus, which may inform future endeavors and evolution of paramedicine. The objective of this study was to explore the existing discourse in paramedicine research to reflect on the academic pursuits of this community. Methods We searched Medline, Embase, CINAHL, Google Scholar and Web of Science from January, 2006 to April, 2019. We further refined the yield using a ranking formula that prioritized journals most relevant to paramedicine, then sampled randomly in two-year clusters for full text review. We extracted literature type, study topic and context, then used elements of qualitative content, thematic, and discourse analysis to further describe the sample. Results The initial search yielded 99,124 citations, leaving 54,638 after removing duplicates and 7084 relevant articles from nine journals after ranking. Subsequently, 2058 articles were included for topic categorization, and 241 papers were included for full text analysis after random sampling. Overall, this literature reveals: 1) a relatively narrow topic focus, given the majority of research has concentrated on general operational activities and specific clinical conditions and interventions (e.g., resuscitation, airway management, etc.); 2) a limited methodological (and possibly philosophical) focus, given that most were observational studies (e.g., cohort, case control, and case series) or editorial/commentary; 3) a variety of observed trajectories of academic attention, indicating where the evolution of paramedicine is evident, areas where scope of practice is uncertain, and areas that aim to improve skills historically considered core to paramedic clinical practice. Conclusions Included articles suggest a relatively narrow topic focus, a limited methodological focus, and observed trajectories of academic attention indicating where research pursuits and priorities are shifting. We have highlighted that the academic focus may require an alignment with aspirational and direction setting documents aimed at developing paramedicine. This review may be a snapshot of scholarly activity that reflects a young medically directed profession and systems focusing on a few high acuity conditions, with aspirations of professional autonomy contributing to the health and social well-being of communities.

One of the main priorities of emergency services is to minimize the response time to calls. In the process of proper allocation of emergency vehicles, maps of emergency vehicle accessibility are found to be helpful. These maps represent areas within which emergency services can reach the specified location within a certain time. Calculating travel times requires taking into account the rapidly changing current road conditions. This paper presents a method for dynamically generating maps of emergency vehicle accessibility, considering network models and irregular computational grids.

The scale of attacks on healthcare has become more visible and its impact greater in recent armed conflicts in Ukraine, Sudan and Myanmar. In these conflicts, combatants systematically target health facilities and ambulances. We need to ensure that attacks on healthcare do not become the new norm amongst governmental troops and non-State armed groups. There is limited evidence about why and how attacks on healthcare have become "normal" practice amongst many combatants, despite the likely tactical and strategic costs to themselves. We are convinced that the problem now needs to be tackled like any other public health issue by assessing: the scale of the problem; who is the most at risk; identifying risk factors; developing new interventions to prevent the risks or address the issue; and evaluating the effectiveness of these interventions.

The COVID-19 pandemic led to massively increased emergency medical services (EMS) activity. The need to decontaminate emergency vehicles after conveying a suspected or confirmed patient to the hospital represented a critical step, slowing the activities and impacting the number of available ambulances. This brief paper analyzes the flow of EMS processes according to the Lean Thinking management approach, which focuses on reducing waste in a production cycle. The different steps of the whole process (arrival to the Emergency Department, handover phase, decontamination, return to service, and the required transfers) and a series of strategies are discussed. The organization (centralized or delocalized), number, and location of the decontamination centers impact transfers and waiting times and, consequently, the availability of ambulances. Optimizing these processes may lead to a global performance improvement, reducing transfers and time, with greater availability of emergency vehicles.

Emergency medical services (EMS) are a unique workforce providing 24/7 emergency care across high-income countries (HICs) and low- and middle-income countries (LMICs). Although traditionally perceived as first responders to traumatic and medical emergencies, EMS scope of practice has evolved to respond to the changing needs of communities, including a growing demand for community-based palliative care. Public health provides a useful framework to conceptualise palliative and end-of-life care in community-based settings. However, countries lack public policy frameworks recognising the role EMS can play in initiating palliative approaches in the community, facilitating goals of care at end of life and transporting patients to preferred care settings. This article aims to explore the potential role of EMS in a public health palliative care approach in a critical discussion essay format by (1) discussing the utility of EMS within a public health palliative care approach, (2) identifying the current barriers preventing public health approaches to EMS palliative care provision and (3) outlining a way forward through priorities for future research, policy, education and practice. EMS facilitate equitable access, early provision, expert care and efficacious integration of community-based palliative care. However, numerous structural, cultural and practice barriers exist, appearing ubiquitous across both HICs and LMICs. A Public Health Palliative Care approach to EMS Framework highlights the opportunity for EMS to work as a linking asset to build capacity and capability to support palliative care in place; connect patients to health and community supports; integrate alternative pathways by engaging multidisciplinary teams of care; and reduce avoidable hospital admissions by facilitating home-based deaths. This article articulates a public health approach to EMS palliative and end-of-life care provision and offers a preliminary framework to illustrate the components of a potential implementation and policy strategy.

Healthcare vehicles such as ambulances are the key drivers for digital and pervasive remote care for elderly patients. Thus, Healthcare Vehicular Ad Hoc Network (H-VANET) plays a vital role to empower the digital and Intelligent Transportation System (ITS) for the smart medical world. Quality of Service (QoS) performance of vehicular communication can be improved through the development of a robust routing protocol having enhanced reliability and scalability. One of the most important issues in vehicular technology is allowing drivers to make trustworthy decisions, therefore building an efficient routing protocol that maintains an appropriate level of Quality of Service is a difficult task. Restricted mobility, high vehicle speeds, and continually changing topologies characterize the vehicular network environment. This paper contributes in four ways. First, it introduces adaptive, mobility-aware, and reliable routing protocols. The optimization of two routing protocols which are based on changing nature topologies of the network used for vehicular networks has been performed, amongst them, Optimized Link State Routing (Proactive) and Ad-hoc on Demand Distance Vector (Reactive) are considered for Packet Delivery Ratio (PDR) and throughput. Furthermore, Packet Loss Ratio (PLR), and end-to-end (E2E) delay parameters have also been calculated. Second, a healthcare vehicle system architecture for elderly patients is proposed. Third, a Platoon-based System model for routing protocols in VANET is proposed. Fourth, a dynamic channel model has been proposed for the vehicle to vehicle communication using IEEE8011.p. To optimize the QoS, the experimental setup is conducted in a discrete Network Simulator (NS-3) environment. The results reveal that the AODV routing protocol gives better performance for PDR as well as for PLR and the communication link established is also reliable for throughput. Where OLSR produces a large average delay. The adoptive mobility-aware routing protocols are potential candidates for providing Intelligent Transportation Systems with acceptable mobility, high reliability, high PDR, low PLR, and low E2E delay.

This study aimed to determine whether the Hamad Medical Corporation Ambulance Service (HMCAS) personnel fulfil the pre-hospital readiness requirements for hazardous material and chemical, biological, radiological, and nuclear (HazMat-CBRN) incidents. This cross-sectional study performed an online assessment of non-specialist paramedics’ behaviour and knowledge about HazMat-CBRN incident management, followed by a ‘HazMat-CBRN incident management’ course with pre-and post-activity assessments. The validity and reliability of the knowledge assessment questions were also tested. The pre-and-post course assessement responses revealed certain deficiencies in staff knowledge. The multiple linear regression and paired groups t-test demonstrated that this was rectified after the training intervention. The results indicate that the implemented course helped HMCAS staff acquire a satisfactory level of knowledge to ensure their readiness for safe and effective responses to potential HazMat-CBRN incidents in Qatar.

Police, ambulance, and mental health tri-response services are a relatively new model of responding to people experiencing mental health crisis in the community, though limited evidence exists examining their efficacy. Reducing unnecessary involuntary detentions and emergency department presentations is believed to be a benefit of this model. A systematic review was performed to review the evidence base around the relationship between the police, ambulance, mental health tri-response models in reducing involuntary detentions of people experiencing mental health crisis. We searched key health databases for clinical studies and grey literature as per a previously published protocol. Two researchers completed title and abstract screening and full text screening. Our search identified 239 citations. No studies or grey literature met the inclusion criteria. We report an empty review. It is recommended that further investigation of the tri-response mental health crisis model be undertaken to determine its effectiveness and value as a health and emergency service initiative.

Background: NHS ambulance service staff are at risk of poor physical and mental wellbeing because of the likelihood of encountering stressful and traumatic incidents. While reducing sickness absence and improving wellbeing support to ambulance staff is a key NHS priority, few studies have empirically documented a national picture to inform policy and service re-design. The study aimed to understand how ambulance service trusts in England deal with staff health and wellbeing, as well as how the staff perceive and use wellbeing services.Methods: To achieve our aim, we undertook semi-structured telephone interviews with health and wellbeing leads and patient-facing ambulance staff, as well as undertaking documentary analysis of ambulance trust policies on wellbeing. The study was conducted both before and during the UK first COVID-19 pandemic wave. The University of Lincoln ethics committee and the Health Research Authority (HRA) granted ethical approval. Overall, we analysed 57 staff wellbeing policy documents across all Trusts. Additionally, we interviewed a Health and Wellbeing Lead in eight Trusts as well as 25 ambulance and control room staff across three Trusts.Results: The study highlighted clear variations between organisational and individual actions to support wellbeing across Trust policies. Wellbeing leads acknowledged real 'tensions' between individual and organisational responsibility for wellbeing. Behaviour changes around diet and exercise were perceived to have a positive effect on the overall mental health of their workforce. Wellbeing leads generally agreed that mental health was given primacy over other wellbeing initiatives. Variable experiences of health and wellbeing support were partly contingent on the levels of management support, impacted by organisational culture and service delivery challenges for staff.Conclusion: Ambulance service work can impact upon physical and mental health, which necessitates effective support for staff mental health and wellbeing. Increasing the knowledge of line managers around the availability of services could improve engagement. [ABSTRACT FROM AUTHOR]

Background: Emergency medical care, including prehospital treatment, forms an important component of any healthcare system. Like most low-middle-income countries, Nepal has an emergency medical system that can be described as underdeveloped. Emergency physicians navigating this system may experience challenges or barriers in their treatment of patients. This study aimed to investigate physicians' perspectives on emergency and prehospital patient management in a low-income country, Nepal, and to understand the challenges and barriers they perceive in emergency treatment including both the prehospital treatment and the immediate in-hospital treatment at the emergency department. Methods: Using a qualitative study, eight semi-structured interviews with physicians working in a Nepalese emergency department were performed. The interviews were conducted between September and November 2021 and were audio-recorded and transcribed verbatim. Data were subsequently analyzed using the systematic text condensation method. Results: Four main themes and associated sub-themes were identified: (1) patients' sociocultural, educational, and financial factors (such as financial issues and financial inequality) and regional differences; (2) emergency department's organization and resources concerning human and material resources, protocols, and guidelines; (3) problems with the emergency department (ED) service's qualities and availability caused by an insufficient integration of the ED and the EMS, prehospital resources, and financial interests in the EMS; and (4) surrounding healthcare system's impact on the ED where, especially, the levels of organized primary care, governmental responsibilities, and healthcare structure were addressed. Conclusions: The physicians identified numerous regularly encountered challenges and barriers. These challenges stretched beyond the ED and into various aspects of society. The patients' financial problems were described as the greatest problem, restricting the treatment due to a given patient's inability or unwillingness to pay for the required procedures. The physicians were thus restricted in completing their duties to the desired levels. The low quality of prehospital care and a lack of education and awareness of common diseases and symptoms in a significant proportion of patients were identified by many participants as being significant issues. The aforementioned challenges or barriers directly resulted in patients arriving in critical conditions that could have been avoided if the disease were treated earlier. [ABSTRACT FROM AUTHOR]

Abstract Background The transport of patients from one location to another is a fundamental part of emergency medical services. However, little interest has been shown in the actual driving of the ambulance. Therefore, this review aimed to investigate how the driving of the ambulance affects the patient and the medical care provided in an emergency medical situation. Methods A systematic integrative review using both quantitative and qualitative designs based on 17 scientific papers published between 2011 and 2020 was conducted. Results Ambulance driving, both the actual speed, driving pattern, navigation, and communication between the driver and the patient, influenced both the patient’s medical condition and the possibility of providing adequate care during the transport. The driving itself had an impact on prehospital time spent on the road, safety, comfort, and medical issues. The driver’s health and ability to manage stress caused by traffic, time pressure, sirens, and disturbing moments also significantly influenced ambulance transport safety. Conclusions The driving of the ambulance had a potential effect on patient health, wellbeing, and safety. Therefore, driving should be considered an essential part of the medical care offered within emergency medical services, requiring specific skills and competence in both medicine, stress management, and risk approaches in addition to the technical skills of driving a vehicle. Further studies on the driving, environmental, and safety aspects of being transported in an ambulance are needed from a patient’s perspective.

Abstract Background Internationally increasing demand for emergency care is driving innovation within emergency services. The Alternative Pre-Hospital Pathway (APP) Team is one such Community Emergency Medicine (CEM) initiative developed in Cork, Ireland to target low acuity emergency calls. In this paper the inception of the APP Team is described, and an observational descriptive analysis of the APP Team’s service data presented for the first 12 months of operation. The aim of this study is to describe and analyse the APP team service. Methods The APP Team, consisting of a Specialist Registrar (SpR) in Emergency Medicine (EM) and an Emergency Medical Technician (EMT) based in Cork, covers a mixed urban and rural population of approximately 300,000 people located within a 40-min drive time of Cork University Hospital. The team are dispatched to low acuity 112/999 calls, aiming to provide definitive care or referring patients to the appropriate community or specialist service. A retrospective analysis was performed of the team’s first 12 months of operation using the prospectively maintained service database. Results Two thousand and one patients were attended to with a 67.8% non-conveyance rate. The median age was 62 years, with 33.0% of patients aged over 75 years. For patients over 75 years, the non-conveyance rate was 62.0%. The average number of patients treated per shift was 7. Medical complaints (319), falls (194), drug and alcohol related presentations (193), urological (131), and respiratory complaints (119) were the most common presentations. Conclusion Increased demand for emergency care and an aging population is necessitating a re-design of traditional models of emergency care delivery. We describe the Alternative Pre-Hospital Pathway service, delivered by an EMT and an Emergency Medicine SpR responding to low acuity calls. This service achieved a 68% non-conveyance rate; our data demonstrates that a community emergency medicine outreach team in collaboration with the National Ambulance Service offering Alternative Pre-Hospital Pathways is an effective model for reducing conveyances to hospital.

ObjectivesWe aimed to identify, appraise, and synthesise the qualitative literature to develop theory on heroism and paramedic practice.Hypothesis/research questionWhat does published literature tell us about heroism and paramedic practice?SettingParamedics and other healthcare workers (HCWs) faced an outpouring of public support for them early in the COVID-19 pandemic which brought into focus the relationship between them and society, where they are portrayed as heroes.ParticipantsWe conducted a metasynthesis using Evolved Grounded Theory and procedural guidelines of Noblit and Hare to guide analysis. Preferred Reporting Items for Systematic Reviews and Meta-analysis Protocols (PRISMA-P) guidelines were also applied.Results151 papers were retrieved and eleven included in the final sample. Studies were moderate to very low quality, involving a wide range of methodologies and settings; none specifically explored heroism and paramedic practice. The following interrelated themes were constructed on heroism and paramedic practice: (a) Myth, Folk law, and storytelling in heroism and paramedic practice (b) The epic journey of heroism and paramedic practice (c) Heroes and Zeroes: The fluctuating Societal Value in heroism and paramedic practice (d) Politicisation, and objectification in Heroism and Paramedic practice.ConclusionParamedics have long been characterised as heroes, but this may not reflect their everyday experiences. Heroism in paramedic practice can provide scripts for prosocial action, inspiring others, and leading to more social heroic actions. Paramedics may however be ambivalent to such heroism narratives, due to politicisation, and objectification in the media and society. This metasynthesis is only one of many possible constructions of heroism and paramedic practice and is the first point in making sense of and developing theory on heroism and paramedic practice.Study registrationPROSPERO: CRD42021234851.

A rough road surface produces strong or continuous vibration in an ambulance, which causes feeling of discomfort, severe pain or sometimes deterioration of physical condition to injured or ill persons. With the aim of reducing such harmful vibration for safe and reliable medical emergency transportation services, this paper proposes a method to find out rough road surfaces from drive data of ambulances and to give them the priority for future pavement repair. There are four steps in the prioritization process: The first step is to collect drive data including information on location, speed and vibration with a smartphone. According to ISO2631-1, the vibration is quantified as a running r.m.s of the frequency-weighted acceleration. In the second step, meaningless data such as small vibration and extremely slow speed data are removed. Then, depending on the location and the traveling direction of the ambulance when the data were recorded, the data form clusters, which are candidates of road repair zones. Finally, each cluster is prioritized by the evaluation function. The larger amount of strong-vibration and slow-speed data are included in the cluster, the higher priority is given to it. An example of application to three ambulances is presented. The high priority clusters were well matched to the road surfaces that the ambulance crews were aware of as strong vibration zones. It is also shown that at least one and a half months are required in collection of the drive data to decide on the top ten clusters.

Fixation using cephalomedullary nails (CMNs) with additional cement augmentation (CA) was developed as a novel treatment option for the osteosynthesis of osteoporotic trochanteric fractures, though the effectiveness of CA on early postoperative mobility remains uncertain. This multicenter prospective cohort study aimed to estimate the effectiveness of CA on early postoperative mobility in patients with trochanteric fractures. We enrolled patients with femoral trochanteric fractures aged >60 years who were able to walk independently before the injury. The primary outcome was the postoperative 3-day cumulated ambulation score (CAS); the secondary outcome was the visual analog scale (VAS) pain score at rest and during movement on postoperative days 1–3. The outcomes of the patients treated using CMNs with or without CA were compared. Sixty-three eligible patients were categorized into CA (n = 32) and control (n = 31) groups. In univariate analysis, the CA group had significantly higher CAS values, lower VAS scores at rest on day 1 postoperatively, and lower VAS scores during movement on day 3. In multivariable linear regression analyses, the CA group had significantly higher CAS values (beta, 2.1; 95% confidence interval, 0.5 to 3.6; p = 0.01). The CA group had a negative adjusted beta value in their VAS scores during movement. This study indicated that CA was associated with a high CAS value in patients with geriatric trochanteric fractures. However, CA was not associated with pain reduction at rest and during movement during the initial postoperative days. [ABSTRACT FROM AUTHOR]
