The cost effectiveness of medical treatments is not precisely known due to the compounding effect of multiple determining factors. Ambulance response time (RT) to emergency calls is exploited to learn more about the effect of the timing of treatment on health outcomes. This causal relation is identified by exploiting rainfall at the time of the ambulance run as a shock to RT. The analysis focuses on patients who have undergone a cardiac event and shows that a one-minute increase in average RT leads to 105 more deaths each year in one Italian region. Finally, the economic value of the lives that would be saved by reducing RT is quantified to facilitate policymaking., (© 2023 The Authors. Health Economics published by John Wiley & Sons Ltd.)

This study aimed to explore factors associated with ambulance use and emergency department (ED) visits among people with dementia in the month before death. A web-based survey of bereaved family caregivers of people with dementia was conducted in March 2020. Multivariate logistic regression analyses were conducted with ambulance use and ED visits in the month before death as dependent variables. Age and gender of people with dementia and their family caregivers, home care use, decision-makers, comorbidities, degree of independence in daily living, and caregivers' preparedness for death were independent variables. Data were collected from 817 caregivers of people with dementia who had died at hospitals (52.4%), long-term care facilities (25.0%), or own homes (22.4%). Caregivers' lack of preparedness for death was significantly associated with ambulance use in the month before death. Comorbidites and males with dementia were significantly associated with ED visits in the month before death. Better death preparedness of family caregivers may reduce ambulance use for symptoms that can be more effectively addressed by palliative care than acute care for people with dementia., (© 2023 The Authors.

Digital technology has an essential role in the development and application of innovations within the health care system. Its application is not limited to the hospital environment but extends to the emergency medical services system. The experimental phase of the shift to electronic emergency medical services documentation was performed within the Azienda Sanitaria Universitaria Friuli Centrale of Udine (Italy), a local health authority covering about 533 000 inhabitants. Considering the results of this study, we believe it is important to continue to update the methods of data collection and analysis in correlation with the management and outcomes of the patients.

Purpose: The aim of this study was to assess the effect of fluid administration by emergency life-saving technicians (ELST) on the prognosis of traffic accident patients by using a propensity score (PS)-matching method., Methods: The study included traffic accident patients registered in the JTDB database from January 2016 to December 2017. The main outcome was hospital mortality, and the secondary outcome was cardiopulmonary arrest on hospital arrival (CPAOA). To reduce potential confounding effects in the comparisons between two groups, we estimated a propensity score (PS) by fitting a logistic regression model that was adjusted for 17 variables before the implementation of fluid administration by ELST at the scene., Results: During the study period, 10,908 traffic accident patients were registered in the JTDB database, and we included 3502 patients in this study. Of these patients, 142 were administered fluid by ELST and 3360 were not administered fluid by ELST. After PS matching, 141 patients were selected from each group. In the PS-matched model, fluid administration by ELST at the scene was not associated with discharge to death (crude OR: 0.859 [95% CI, 0.500-1.475]; p = 0.582). However, the fluid group showed statistically better outcome for CPAOA than the no fluid group in the multiple logistic regression model (adjusted OR: 0.231 [95% CI, 0.055-0.967]; p = 0.045)., Conclusion: In this study, fluid administration to traffic accident patients by ELST was associated not with hospital mortality but with a lower proportion of CPAOA., (© 2021.

Objective: Nitrous oxide (Entonox ® ) and methoxyflurane (Penthrox ® ) are inhaled analgesics administered in paramedicine. Occupational exposure to nitrous oxide has been associated with negative health effects, and may inhibit professional capability. The effect of occupational exposure to methoxyflurane has not yet been clearly determined. This study identifies the frequency and duration of ambulance officer (AO) occupational exposure to nitrous oxide and methoxyflurane to provide a foundation for future assessments of occupational toxicity risk., Methods: A retrospective database review of Patient Report Forms (PRFs) in 11 months between February 2016 and February 2018 was conducted. Nitrous oxide was available for the first 5 months studied, followed by 6 months methoxyflurane availability. AO-specific measures of attendance, rate of inhaled analgesic use, and duration of analgesic use were determined. Subgroup analysis by AO qualification and rostered work hours was undertaken., Results: A total of 46,759 PRFs were examined, identifying 1,033 cases of nitrous oxide administration and 1456 cases of methoxyflurane was administration. There was a significant increase in the proportion of cases where inhaled analgesia was administered following the replacement of nitrous oxide with methoxyflurane. Relative risk of exposure to methoxyflurane compared with nitrous oxide was 1.22, while median duration of each exposure remained unchanged (32 vs. 33 min)., Conclusions: Methoxyflurane via the Penthrox ® inhaler was more likely to be administered than nitrous oxide. Most AOs are infrequently exposed to inhaled analgesics and are exposed for durations slightly greater than previously reported. Relative risk of exposure was greatest for lower-qualified AOs. Peak number of exposures and duration values suggest a subset of AOs with higher occupational health risk., (© 2021.

Objective: Air pollutants play a crucial role in human health and disease. Emergency ambulance dispatch data have excellent potential for public and environmental health research. This study aimed at investigating the impact of short-term exposure to air pollutants on the emergency ambulance dispatches., Methods: We used data on emergency ambulance dispatches in Shanghai Municipality, China, from April 1, 2016 to December 31, 2017. The association of the daily emergency ambulance dispatches with air pollutants including PM 2.5 (particles ≤ 2.5 μm in aerodynamic diameter), PM 10 , O 3 , NO 2 and SO 2 was analyzed with the use of time-series analyses., Results: A total of 310,825 emergency ambulance dispatches for acute illness occurred in Shanghai during the study period. An increase in PM 2.5 by 10 μg/m 3 at lag1 and lag2 was shown to increase the risk of emergency ambulance dispatches (RR for lag1 = 1.05, 95% CI 1.00-1.11, RR for lag2 = 1.07, 95% CI 1.01-1.12). PM 10 , NO 2 , and SO 2 also showed significant associations with emergency ambulance dispatches in single-pollutant models. Cause-specific analyses showed an elevation in PM 2.5 by 10 μg/m 3 was associated with an increased risk of emergency ambulance dispatches related to respiratory diseases on the current day (lag0, RR 1.17, 95% CI 1.01-1.33), while the impact on emergency ambulance dispatches related to other diseases presented 1-3 days later. The other pollutants have the similar trend., Conclusions: Our findings show a strong relationship between ambient air pollutants and emergency ambulance dispatches. Our study contributes to the growing body of evidence describing the adverse health effects of ambient air pollution and will benefit ambulance services for early warning and effective ambulatory planning., (© 2021.

Objectives: To describe the patterns of personal emergency response systems (PERS) use in a statewide cohort of older Australians., Methods: PERS data from clients enrolled in the Personal Alarm Victoria program between January 2014 and June 2017 were analysed. Alarm activation reasons were extracted, and a medical record audit was performed for a sub-cohort of patients admitted to a local hospital following an alarm event. Descriptive statistics were used., Results: There were 42,180 clients enrolled during the study (mean age 80 years, 80% female, 93% living alone). An ambulance attended 44% of the fall-related events and 81% of events coded as unwell. Activation reasons were distributed equally between a fall and feeling unwell, and a repeating pattern of activation reasons was observed. In our sub-cohort (n = 92), the majority of admissions (86%) followed an alarm activation coded as unwell., Conclusion: We demonstrated recurring patterns associated with the reasons for alarm use., (© 2021 AJA Inc.)

Introduction: Ambulance personnel are exposed to traumatic and stressful situations, which can increase the risk of mental health conditions, such as post-traumatic stress disorder (PTSD). High rates of PTSD have been found in ambulance personnel (Petrie et al., 2018), but no review is available to examine post-traumatic growth (PTG - positive psychological change following a trauma) in this population. This literature review provides an overview of the prevalence rates and facilitators that may contribute to PTG in ambulance personnel. Methods: A systematic search was conducted on EBSCOhost in January 2024 across the following six databases: Academic Search Ultimate, PsycINFO, PsycARTICLES, MEDLINE, ERIC and Cumulative Index to Nursing and Allied Health Literature (CINAHL) Ultimate. Results: Eleven papers were identified for this review. Pooled prevalence of PTG was moderate (52%), and facilitators for PTG were grouped into five categories: coping style/strategies, resilience, personality traits, gender and incident characteristics. Conclusions: Numerous facilitators contributed to the development of PTG, although these did not arise in all papers. The quality of research ranged from satisfactory to excellent. Evidence suggested that adaptive coping style, high levels of resilience, the absence of a personality trait (neuroticism) and being female may facilitate PTG. Further research is needed to support the reliability of findings. [ABSTRACT FROM AUTHOR]

Objective: There are nearly 1000 annual ambulance crashes within the United States involving pediatric patients. In 2012 National Highway Traffic Safety Administration/US Department of Transportation released Best-Practice Recommendations for the Safe Transportation of Children in Emergency Ground Ambulances. The aim of our study was to measure emergency medical services (EMS) providers' knowledge and opinions of how to safely transport pediatric patients. In addition, we aimed to gather information on barriers to safe pediatric transport., Methods: Members of 1 urban and 2 suburban EMS agencies completed an anonymous survey that assessed level of training, years of experience, exposure to pediatric patients, knowledge of best practices, and opinions about barriers to safe transport of pediatric patients., Results: A total of 114 EMS providers answered the survey. Sixty-three percent were basic life support providers who had more than 10 years of experience in EMS. Ninety-six percent reported that they transported 0 to 5 pediatric patients per week. Twenty percent reported being trained on pediatric safe transport practices. Thirty-two percent of providers reported that personnel did not drive faster when transporting a sick pediatric patient. Eighty-six percent reported that it was unsafe to transport a child on a parent's lap, but 27% reported that it was appropriate to transport a newborn on the stretcher with mom. Thirty-eight percent were comfortable identifying proper restraint system/seat for pediatric patients, and only 35% were comfortable installing/using these devices. Provider-reported barriers to safe transport were identified., Discussion: Our survey demonstrates that despite published best practices for the safe transport of children, many providers are unfamiliar with the safest way to transport these patients. In addition, we identified several existing barriers that may contribute to unsafe practices.

Vehicular ad hoc networks (VANETs) can support safety-critical applications such as the safe and fast movement of emergency vehicles while preventing crashes, delays, and congestion involving emergency vehicles. A simulation approach to evaluate ambulance transit using VANET capabilities is presented in this paper for a real-life road network taken in and around the University of Missouri–Kansas City, USA. Three different VANET functional scenarios are compared with a base scenario (SC-1) which depicts the present-day traffic pattern and vehicle behaviors. In the three scenarios, the second one (SC-2) adds vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications along with the present-day traffic pattern; ambulances use VANETs simply to announce their arrival. The third scenario (SC-3) provides functionalities for ambulances to rerouting when they learn about a current or an anticipated road congestion. And the fourth scenario (SC-4) adds vehicle rerouting capabilities, so ambulance routes can be sent to vehicles, and they can avoid the ambulance path. Performance results are presented and evaluated for metrics such as delay, packet drop ratio, the average speed of the ambulance, average vehicle density, and ambulance message interval time. From the simulation results, it was observed that the ambulance transit time reduces by 12.52%, 14.65%, and 18.75% for SC-2, SC-3, and SC-4, respectively, as compared with SC-1, while the average ambulance speed increases by 14.49%, 15.57%, and 20.90% for SC-2, SC-3, and SC-4, respectively, when compared with SC-1. This paper provides substantial evidence that VANET capabilities for emergency vehicles can enhance crash protection and reduce the commute time for emergency response. [ABSTRACT FROM AUTHOR]

Objective: The objective of the present study is to examine variations in paramedic care of the agitated patient, including verbal de-escalation, physical restraint and sedation, provided by ambulance services in Australia and New Zealand., Methods: To examine the care of agitated patients, we first identified and reviewed all clinical practice guidelines for the management of agitated patients in Australian and New Zealand ambulance services between September and November 2018. We then conducted a structured questionnaire to obtain further information on the training, assessment and care of agitated patients by the ambulance services. Two authors extracted the data independently, and all interpretations and results were reviewed and confirmed by relevant ambulance services., Results: There were 10 independent clinical practice guidelines for the care of agitated patients in the 10 ambulance services. All services reported training in the management of agitated patients, and two services used a validated tool to assess the level of agitation. All services used physical restraint, although six services required police presence to restrain the patient. All ambulance services used some form of sedation, typically divided into the management of mild to moderate, and severe agitation. The most common agent for sedation was midazolam, while ketamine was the most common agent for sedating severely agitated patients. The maximum dose was varied, and contraindications for sedating agents varied between services., Conclusions: There were wide variations across the ambulance services in terms of the assessment of agitation, as well as the use of physical restraint and sedation., (© 2019 Australasian College for Emergency Medicine.)

The risk of dying or being injured as a result of traffic collisions is higher for medical emergency responders than for other professional drivers. This systematic review synthesizes the literature regarding the collisions of ambulances, focusing on the prevalence and characteristics surrounding such events. Keywords including paramedics and traffic collisions were searched in papers available in PubMed from January 1990 to July 2021. Two independent reviewers screened the abstracts of 2494 papers and ended up with 93 full-text articles to assess for eligibility, of which 26 papers were finally kept for this review. There was a total of 18 studies conducted in the United States, followed by 3 in Turkey, 2 in Taiwan, 1 in both the United States and Canada, 1 in France, and 1 in Poland. There is a high record of injury and fatal collisions for ambulances compared to other commercial or similarly sized vehicles. Drivers less than 35 years old with low experience and a history of citations are more likely to be involved in such collisions. Ambulance collisions are more likely to happen in urban areas and intersections are the riskiest locations. Most collisions occur when the ambulance is responding to an emergency call (i.e., going to the patient or the hospital) and using lights and sirens. Tailored preventive policies and programs for improving paramedics' safety should be sought to reduce the burden of these occupational collisions. [ABSTRACT FROM AUTHOR]

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]

Background: Ambulance personnel are frequently exposed to traumatic accidents, which makes them a high risk for poor mental health. High rates of Post-Traumatic Stress Symptoms (PTSS) have been found within ambulance personnel samples but no review has been completed to examine the factors that may be implicated in the development of these symptoms. This literature review provides an overview of the factors that predict PTSS in ambulance personnel. Methods: A systematic search strategy was conducted in April 2020 across the following four databases: PsycINFO, PsycARTICLES, MEDLINE and Cumulative Index to Nursing and Allied Health Literature (CINAHL). Results: Eighteen papers were included in this review, and the predictive factors examined were grouped into four categories: coping style, personal factors, environmental factors and organisational factors. Conclusions: An array of factors across the four categories were implicated in the development of PTSS, but these tended to be indicated in only one or two papers. Evidence was found to suggest that dysfunctional coping styles, reduced levels of some personality traits, proximity and nature of the critical incident and high levels of organisation stress can all lead to PTSS. Further research is needed to support the reliability of findings. [ABSTRACT FROM AUTHOR]

The benefits of community-based, grassroots food practices, such as community gardens or kitchens, are widely acknowledged. However, they have also been shown to support neoliberal and exclusionary dynamics. This paper examines this contradiction on the ground by unpacking the processes and mechanisms through which these initiatives reproduce, reinforce or challenge social inequities and injustices in the city. It suggests the concept of community food space to look at the articulation of practices and intentions within these groups, and highlight emancipatory practices situated around food rather than simply about food. The paper draws upon an ongoing militant ethnography into community food spaces in Berlin, Germany. Exploring the complex and diverse landscape of Berlin food activism, it illuminates the ways in which food may be used to perpetuate unjust social configurations or, on the contrary, to advance social justice at both local and structural levels.

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: Linked datasets for trauma system monitoring should ideally follow patients from the prehospital scene to hospital admission and post-discharge. Having a well-defined cohort when using administrative datasets is essential because they must capture the representative population. Unlike hospital electronic health records (EHR), ambulance patient-care records lack access to sources beyond immediate clinical notes. Relying on a limited set of variables to define a study population might result in missed patient inclusion. We aimed to compare two methods of identifying prehospital trauma patients: one using only those documented under a trauma protocol and another incorporating additional data elements from ambulance patient care records., Methods: We analyzed data from six routinely collected administrative datasets from 2015 to 2018, including ambulance patient-care records, aeromedical data, emergency department visits, hospitalizations, rehabilitation outcomes, and death records. Three prehospital trauma cohorts were created: an Extended-T-protocol cohort (patients transported under a trauma protocol and/or patients with prespecified criteria from structured data fields), T-protocol cohort (only patients documented as transported under a trauma protocol) and non-T-protocol (extended-T-protocol population not in the T-protocol cohort). Patient-encounter characteristics, mortality, clinical and post-hospital discharge outcomes were compared. A conservative p-value of 0.01 was considered significant RESULTS: Of 1 038 263 patient-encounters included in the extended-T-population 814 729 (78.5 %) were transported, with 438 893 (53.9 %) documented as a T-protocol patient. Half (49.6 %) of the non-T-protocol sub-cohort had an International Classification of Disease 10th edition injury or external cause code, indicating 79644 missed patients when a T-protocol-only definition was used. The non-T-protocol sub-cohort also identified additional patients with intubation, prehospital blood transfusion and positive eFAST. A higher proportion of non-T protocol patients than T-protocol patients were admitted to the ICU (4.6% vs 3.6 %), ventilated (1.8% vs 1.3 %), received in-hospital transfusion (7.9 vs 6.8 %) or died (1.8% vs 1.3 %). Urgent trauma surgery was similar between groups (1.3% vs 1.4 %)., Conclusion: The extended-T-population definition identified 50 % more admitted patients with an ICD-10-AM code consistent with an injury, including patients with severe trauma. Developing an EHR phenotype incorporating multiple data fields of ambulance-transported trauma patients for use with linked data may avoid missing these patients., Competing Interests: Declaration of competing interest Matthew Miller reports financial support was provided by New South Wales Institute for Trauma and Injury Management (ITIM).

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]

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]

The main purpose of this paper is to demonstrate how important it is for the Ministry of Internal Affairs to have a sufficient budget to carry out the missions entrusted by law. The Ministry of Internal Affairs has very important responsibilities in terms of maintaining public order and intervention in emergency situations. The Romanian Police, the Romanian Gendarmerie, the Romanian Border Police, which are in charge of maintaining public order, as well as the General Inspectorate for Emergency Situations, which is in charge of extinguishing fires and providing first aid through SMURD ambulances, are active within the Ministry of Internal Affairs. In this paper, the possible negative impacts of the application of the Government's Emergency Ordinances regarding some fiscal-budgetary measures, adopted in 2023, will be presented.

The paper concerns numerical study of the ultra-light seat frame serving transported patients in ambulance. The structure of seat was designed to be built of the carbon fibers, aluminium and steel. The present prototype distinguishes itself with low mass and high strength. During modelling, the stress state and displacement state were verified based on requirements according to regulation ECE14. In simulation, solid, beam and connection elements were employed to consider all the parts of structures. The analysis of the stress state verification based on the assumptions of boundary conditions close to regulation ECE14. The isotropic materials were considered to be in elastic range. In case of composite materials, TSAI-WU (TSW) criterion for assessment of strength was taken into account. Five different variants of seat were taken into consideration to indicate the differences between them. The paper includes the results of analysis of composite structure under static loads which were shown and discussed. [ABSTRACT FROM AUTHOR]

The objective of this study is to determine the impacts of low-intensity heat on human health in regions with hot, humid summers. Current literature has highlighted an increase in mortality and morbidity rates during significant heat events. While the impacts on high-intensity events are established, the impacts on low-intensity events, particularly in regions with hot, humid summers, are less clear. A scoping review was conducted searching three databases (PubMed, EMBASE, Web of Science) using key terms based on the inclusion criteria. We included papers that investigated the direct human health impacts of low-intensity heat events (single day or heatwaves) in regions with hot, humid summers in middle- and high-income countries. We excluded papers written in languages other than English. Of the 600 publications identified, 33 met the inclusion criteria. Findings suggest that low-intensity heatwaves can increase all-cause non-accidental, cardiovascular-, respiratory- and diabetes-related mortality, in regions experiencing hot, humid summers. Impacts of low-intensity heatwaves on morbidity are less clear, with research predominantly focusing on hospitalisation rates with a range of outcomes. Few studies investigating the impact of low-intensity heat events on emergency department presentations and ambulance dispatches were found. However, the data from a limited number of studies suggest that both of these outcome measures increase during low-intensity heat events. Low-intensity heat events may increase mortality. There is insufficient evidence of a causal effect of low-intensity heat events on increasing morbidity for a firm conclusion. Further research on the impact of low-intensity heat on morbidity and mortality using consistent parameters is warranted. [ABSTRACT FROM AUTHOR]

Background: Reconfiguration of the Irish acute hospital sector resulted in the establishment of a Medical Assessment Unit (MAU) in Mallow General Hospital (MGH). We developed a protocol whereby certain patients deemed to be low risk for clinical deterioration could be brought by the National Ambulance Service (NAS) to the MAU following a 999 or 112 call., Aims: The aim of this paper is to report on the initial experience of this quality improvement initiative., Methods: The Plan-Do-Study-Act (PDSA) Cycle for quality improvement was implemented when undertaking this project. A pathway was established whereby, following discussion between paramedic and physician, patients for whom a 999 or 112 call had been made could be brought directly to the MAU in MGH. Strict inclusion and exclusion criteria were agreed. The protocol was implemented from the 1st of September 2022 for a 3-month pilot period., Results: Of 39 patients discussed, 29 were accepted for review in the MAU. One of the 29 accepted patients declined transfer to MAU. Of 28 patients reviewed in the MAU, 7 were discharged home. One patient required same day transfer to a model 4 centre. Twenty patients were admitted to MGH with an average length of stay of 8 days. Frailty and falls accounted for 7 of the admissions and the mean length of stay for these patients was 12 days., Conclusions: Our results have demonstrated the safety, feasibility and effectiveness of this pathway. With increased resourcing, upscaling of this initiative is possible and should be considered., (© 2023. The Author(s), under exclusive licence to Royal Academy of Medicine in Ireland.)

Objective: The objective of this study was to quantify the impact of heatwaves on likelihood of ambulance callouts for Australia., Methods: A systematic review and meta-analysis was conducted to retrieve and synthesise evidence published from 1 January 2011 to 31 May 2023 about the association between heatwaves and the likelihood of ambulance callouts in Australia. Different heatwave definitions were used ranging from excess heat factor to heatwave defined as a continuous period with temperatures above certain defined thresholds (which varied based on study locations)., Results: We included nine papers which met the inclusion criteria for the review. Eight were eligible for the meta-analyses. The multilevel meta-analyses revealed that the likelihood of ambulance callouts for all causes and for cardiovascular diseases increased by 10% (95% confidence interval: 8%, 13%) and 5% (95% confidence interval: 1%, 3%), respectively, during heatwave days., Conclusions: Exposure to heatwaves is associated with an increased likelihood of ambulance callouts, and there is a dose-response association between heatwave severity and the likelihood of ambulance callouts., Implications for Public Health: The number of heatwave days are going to increase, and this will mean an increase in the likelihood of ambulance callouts, thereby, spotlighting the real burden that heatwaves place on our already stressed healthcare system. The findings of this study underscore the critical need for proactive measures, including the establishment of research initiatives and holistic heat health awareness campaigns, spanning from the individual and community levels to the healthcare system, in order to create a more resilient Australia in the face of heatwave-related challenges., Competing Interests: Conflicts of interest Authors declare no conflict of interest., (Copyright © 2023 The Authors.

Introduction: People who call emergency ambulances frequently are often vulnerable because of health and social circumstances, have unresolved problems or cannot access appropriate care. They have higher mortality rates. Case management by interdisciplinary teams can help reduce demand for emergency services and is available in some UK regions. We report results of interviews with people who use emergency ambulance services frequently to understand their experiences of calling and receiving treatment., Methods: We used a two-stage recruitment process. A UK ambulance service identified six people who were known to them as frequently calling emergency services. Through third-sector organisations, we also recruited nine individuals with healthcare experiences reflecting the characteristics of people who call frequently. We gained informed consent to record and transcribe all telephone interviews. We used thematic analysis to explore the results., Results: People said they make frequent calls to emergency ambulance services as a last resort when they perceive their care needs are urgent and other routes to help have failed. Those with the most complex health needs generally felt their immediate requirements were not resolved and underlying mental and physical problems led them to call again. A third of respondents were also attended to by police and were arrested for behaviour associated with their health needs. Those callers receiving case management did not know they were selected for this. Some respondents were concerned that case management could label frequent callers as troublemakers., Conclusion: People who make frequent calls to emergency ambulance services feel their health and care needs are urgent and ongoing. They cannot see alternative ways to receive help and resolve problems. Communication between health professionals and service users appears inadequate. More research is needed to understand service users' motivations and requirements to inform design and delivery of accessible and effective services., Patient or Public Contribution: People with relevant experience were involved in developing, undertaking and disseminating this research. Two public contributors helped design and deliver the study, including developing and analysing service user interviews and drafting this paper. Eight public members of a Lived Experience Advisory Panel contributed at key stages of study design, interpretation and dissemination. Two more public contributors were members of an independent Study Steering Committee., (© 2023 The Authors. Health Expectations published by John Wiley & Sons Ltd.)

Background: With millions of unscheduled patient contacts every year and increasing call outs clustered around the most deprived communities, it is clear the ambulance sector could have a role to play in improving population health. However, the application and value of a public health approach within the ambulance sector has not been comprehensively explored. A scoping review was undertaken to explore the role of the ambulance sector in the delivery of public health interventions and what impact this has on population health and ambulance sector outcomes. Methods: A search strategy was developed on MEDLINE and translated to other major medical and health related bibliographic databases (Embase; CINAHL; HMIC; Science and Social Sciences Citation Index; Cochrane Library) to identify literature published since 2000 in OECD countries. Targeted grey literature, reference list, and citation searching was also carried out. Search results were downloaded to Microsoft Excel and screened by three reviewers according to pre-determined inclusion / exclusion criteria. Data from included studies, such as the type of activity noted within the paper, the population involved and the public health approach that was utilised, was extracted from within the paper using a data extraction form and narratively synthesised. Results: Fifty-two references were included in the final review (37 database searching; 9 reference list searching; 6 grey literature). Included articles were categorised according to the relevant public health domains and subdomains as articulated by the UK Faculty of Public Health: Health improvement domain: Public health education and advice (Health promotion sub-domain) (n=13) Emergency Services personnel providing vaccines (Disease prevention sub-domain) (n=1) Health care public health domain Paramedicine (Service delivery sub-domain) (n=30) Screening tools and referral pathways used by the ambulance sector (Service delivery sub-domain) (n=28) Health intelligence using ambulance sector data (population health management sub-domain) (n=26) Of note, some domains (e.g. health protection) returned nil results. Discussion: The scoping review demonstrates the breadth of public health related activities in which the ambulance sector is involved. However, an overemphasis on demand management outcomes precludes definitive conclusions on the impact of ambulance sector-led public health initiatives on public health outcomes. Future evaluations of public health initiatives should incorporate wider health system perspectives beyond the immediately apparent remit of the ambulance sector. [ABSTRACT FROM AUTHOR]

Purpose: This paper aims to identify human rights violations of patients during the early periods of the COVID-19 pandemic in Ghana by investigating the experiences of people on how health-care professionals discharged their responsibilities during the time in question. Design/methodology/approach: Explanatory design of the mixed methods approach was adopted, with the intention of collecting both quantitative and qualitative data sequentially, and then integrating the results at the interpretation stage. The approach enriched the quality of data collected as it offered the advantage of shedding light on the primary motivations and reasons for attitudes and behaviours and helped to provide an in-depth understanding of how individuals interpret the happenings around them and their experiences. Thus, although some amount of quantitative method was used in the data collection, the core of this paper is based on the qualitative interpretations. Findings: The study reveals that health-care professionals, especially those in the Tema Metropolis, undermined certain fundamental human rights of patients during the early period of the COVID-19 pandemic. This includes failure to provide information to patients about treatment options and potential risks of medications; failure to seek the informed consent of patients before performing medical procedures; denial of access to medical files of patients for transfer; and inability or failure to provide medical ambulances services to patients on time. Originality/value: Although many publications on human rights dimensions and health protective issues on COVID-19 pandemic are available on a global scale, still little information pertaining to experiences of individuals with health-care professionals during the early days of the COVID-19 pandemic, especially in Ghana through the lens of patient's rights exists. This paper, therefore, fills an important gap in health-care management information, critical for policy decision-making processes regarding patient's rights in times of pandemic control.

The introduction of long‐acting injectable buprenorphine preparations for opioid use disorder has been widely heralded as a breakthrough treatment, with several studies indicating positive results when using these medications. In many locations, nurse practitioners prescribe, administer, and monitor long‐acting injectable preparations. The objective of this paper is to explore whether a reduction in dispensed needles and syringes is attributable to increased nurse practitioner prescribing of LAIB. We used a retrospective audit of needles dispensed through the health service needle and syringe program vending machine, and individuals treated with long‐acting injectable buprenorphine by the nurse practitioner led model. In addition, we examined potential factors that may influence changes in the number of needles dispensed. Linear regression found that each individual with opioid dependence treated with long‐acting injectable buprenorphine was associated with 90 fewer needles dispensed each month (p < 0.001). The nurse practitioner led model of care for individuals with opioid dependence appears to have influenced the number of needles dispensed at the needle and syringe program. Although all confounding factors could not be discounted entirely, such as substance availability, affordability, and individuals obtaining injecting equipment elsewhere, our research indicates that a nurse practitioner led model of treating individuals with opioid use disorder influenced needle and syringe dispensing in the study setting.

Hemodialysis patients frequently require ambulance transport to the hospital for dialysis. Some patients require urgent dialysis (UD) within 24 hours of transport to hospital to avoid morbidity and mortality. UD is not available in all hospitals; therefore, predicting patients who need UD prior to hospital transport can help paramedics with destination planning. In this paper, we developed machine learning models for paramedics to predict whether a patient needs UD based on patient characteristics available at the time of ambulance transport. This paper presented a study based on ambulance data collected in Halifax, Canada. Given that relatively few patients need UD, a class imbalance problem is addressed by up-sampling methods and prediction models are developed using multiple machine learning methods. The achieved prediction scores are F1-score=0.76, sensitivity=0.76, and specificity=0.97, confirming that models can predict UD with limited patient characteristics.

Objectives: Dynamic ambulance relocation means that the operators at a dispatch centre place an ambulance in a temporary location, with the goal of optimising coverage and response times in future medical emergencies. This study aimed to scope the current research on dynamic ambulance relocation., Design: A scoping review was conducted using a structured search in PubMed, Scopus and Web of Science. In total, 21 papers were included., Results: Most papers described research with experimental designs involving the use of mathematical models to calculate the optimal use and temporary relocations of ambulances. The models relied on several variables, including distances, locations of hospitals, demographic-geological data, estimation of new emergencies, emergency medical services (EMSs) working hours and other data. Some studies used historic ambulance dispatching data to develop models. Only one study reported a prospective, real-time evaluation of the models and the development of technical systems. No study reported on either positive or negative patient outcomes or real-life chain effects from the dynamic relocation of ambulances., Conclusions: Current knowledge on dynamic relocation of ambulances is dominated by mathematical and technical support data that have calculated optimal locations of ambulance services based on response times and not patient outcomes. Conversely, knowledge of how patient outcomes and the working environment are affected by dynamic ambulance dispatching is lacking. This review has highlighted several gaps in the scientific coverage of the topic. The primary concern is the lack of studies reporting on patient outcomes, and the limited knowledge regarding several key factors, including the optimal use of ambulances in rural areas, turnaround times, domino effects and aspects of working environment for EMS personnel. Therefore, addressing these knowledge gaps is important in future studies., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Background: Not all patients who call the ambulance service are subsequently transported to hospital. In 2018, a quarter of deployments of an emergency ambulance in Bavaria were not followed by patient transport. This study describes factors that influence patient transport rates., Method: This is a retrospective cross-sectional study based on data from all Integrated Dispatch Centres of the Free State of Bavaria in 2018. Included were ambulance deployments without emergency physician involvement, which were subdivided into ambulance deployments without transport and ambulance deployments with transport. The proportion of transported patients were determined for the primary reasons for deployment and for the different community types. On-scene time was compared for calls with and without patient transport. Differences were tested for statistical significance using Chi 2 tests and the odds ratio was calculated to determine differences between groups., Results: Of 510,145 deployments, 147,621 (28.9%) could be classified as ambulance deployments without transport and 362,524 (71.1%) as ambulance deployments with transport.The lowest proportion of patients transported was found for activations where the fire brigade was involved ("fire alarm system" 0.6%, "fire with emergency medical services" 5.4%) and "personal emergency response system active alarm" (18.6%). The highest transport rates were observed for emergencies involving "childbirth/delivery" (96.9%) and "trauma" (83.2%). A lower proportion of patients is transported in large cities as compared to smaller cities or rural communities; in large cities, the odds ratio for emergencies without transport is 2.02 [95% confidence interval 1.98-2.06] referenced to rural communites. The median on-scene time for emergencies without transport was 20.8 min (n = 141,052) as compared to 16.5 min for emergencies with transport (n = 362,524). The shortest on-scene times for emergencies without transport were identified for activations related to "fire alarm system" (9.0 min) and "personal emergency response system active alarm" (10.6 min)., Conclusion: This study indicates that the proportion of patients transported depends on the reason for deployment and whether the emergency location is urban or rural. Particularly low transport rates are found if an ambulance was dispatched in connection with a fire department operation or a personal emergency medical alert button was activated. The on-scene-time of the rescue vehicle is increased for deployments without transport. The study could not provide a rationale for this and further research is needed.

In vehicular energy networks (VENs) operating in smart health care systems (SHaCarS), reputation of vehicles, i.e., ambulances, plays an important role as all functions depend upon it including message sharing, energy trading, etc. Keeping this in view, this paper presents a reputation management scheme. To ensure that the proposed scheme is secure and transparent, Blockchain (BC) technology is used. In the proposed model, the registration of ambulances is performed through a certificate authority (CA). Later, a pseudo mechanism is designed using Elliptic Curve Digital Signature Algorithm, which ensures conditional anonymity and traceability. The ambulances are provided with the pseudo identities, which are mapped with the real identities to prevent disputes. Besides, the proposed scheme uses a Shamir secret sharing (SSS) algorithm to enable distributed revocation in BC based VENs operating in SHaCarS. In addition, the ambulances' reputation information is stored in interplanetary file system (IPFS) in an efficient manner. The hashes are generated by IPFS upon data storage, which are then stored in BC. The performance evaluation of the proposed system is done via extensive simulations. The results show 18–20% reduction in computational overhead and 35–40% reduction in storage overhead. The proposed system's robustness is tested by inducing the 51% attack and the replay attack. In addition, the security analysis of the smart contract is performed using Oyente. The results show that the system proposed for reputation management in the underlying work is robust and computationally efficient. [ABSTRACT FROM AUTHOR]
