Introduction: An ambulance used by an emergency medical service team is the workplace of specialised medical personnel, providing daily transportation for patients in life-threatening conditions, from all walks of life, with numerous diseases and injuries. MRSA (methicillin-resistant Staphylococcus aureus) strains are classified as Gram-positive cocci, characterised primarily by their multidrug resistance. Infections caused by S. aureus have a low treatment success rate and are associated with persistent carrier state. This study aimed to isolate MRSA and MSSA (methicillin-sensitive Staphylococcus aureus) in the emergency vehicle and determine drug resistance of these isolates. Materials and Methods: This study involved an ambulance vehicle operated in central Poland. A total of 39 swabs were taken and evaluated from inside the ambulance on permanent duty. The isolates were analysed using catalase and coagulase assays, Gram staining, culturing on Chapman medium, growth evaluation on agar with 5% sheep blood, and assessing the strains' sensitivities to selected antibiotics. Material was collected from 13 designated points located in the medical compartment and driver's cabin. Results: S. aureus bacteria were detected in 51.28% of the samples, 40% of which were MRSA strains. Despite the application of high disinfection standards for the interior of the ambulance, it was not possible to kill all S. aureus strains, which may be because the pathogens in question produce a biofilm that effectively allows them to survive on various surfaces, including those disinfected. Almost 100% of the MRSA isolates were resistant to antibiotics from the β-lactam group (penicillin, ticarcillin, cefotaxime, and cefoxitin), the macrolide group (erythromycin) and the lincosamide group (clindamycin). However, only a few MRSA strains proved resistant to streptomycin (12.5%) and ciprofloxacin (37.5%). β-lactam antibiotics, such as cefotaxime (100% resistant strains) and penicillin (58% resistant strains), were also ineffective against MSSA. Although MSSA isolates showed slight resistance to ticarcillin and erythromycin (33.3%) and clindamycin (25%), the remaining antibiotics proved effective (no resistant strains). Conclusions: Among the isolated strains, the greatest resistance to β-lactam antibiotics and erythromycin was observed. Multidrug-resistant strains of S. aureus were found in the emergency medical system. Even the MSSA strains detected in the studied ambulance showed resistance to some of the antibiotics used. The prevalence of S. aureus strains within ambulances indicates the need for a high hygiene level in daily prehospital work with patients. [ABSTRACT FROM AUTHOR]

Background: Telehealth has become increasingly essential in healthcare provision, also in the Prehospital Emergency Medical Services (EMS), where live video is implemented as a supplemental tool to assess and triage medical emergency calls. So far, using video for emergency calls seems beneficial for patient assessment and dispatcher-assisted first aid. However, the EMS dispatchers' experiences with and perceptions of using video during emergency calls are largely unexplored. Methods: In 2023, a nationwide survey study was conducted in Denmark, which is covered by five Emergency Medical Dispatch Centers. All Danish EMS dispatchers were invited to participate in the study. The survey explored the dispatchers' experience with using video during emergency calls, the perception of their own video use, and the process of implementing video as a new tool in their working procedure. Main questions were answered on a scale from 1 to 7, where higher scores indicate more agreement. Results: Of the 183 EMS dispatchers employed during the study period, 78% completed the survey. They found video easy to use (median = 7) and found video supportive in guidance and dispatch when the patient's problem was unclear (median = 7), but did not find video suitable for all emergency calls and expressed that complications with the technology was a barrier for using video. The EMS dispatchers were least likely to agree that they choose not to use video due to the risk of being emotionally affected by what they might see (median = 1). When dividing the sample based on EMS dispatcher's gender, age, seniority, and educational background, generally few differences between groups were found. Conclusions: Live video during emergency calls is generally experienced as a useful supplemental tool by EMS dispatchers in Denmark, and the greatest self-perceived barriers for using video were not finding video suitable for all situations and the technology.

Background: Pre-hospital incidents involving pediatric and neonatal patients are infrequent, and clinical characteristics and care for these patients differ from the adult population. Lack of knowledge, guidelines, and experience can make pre-hospital pediatric care challenging, and there is limited research on the epidemiology and best practice of care for this population. We examined the pre-hospital pediatric population in the county of Sør-Trøndelag, Norway, to improve our understanding of this population in our region. Methods: We conducted a retrospective observational cohort study of emergency incidents involving children under twelve years of age with dispatch of Emergency Medical Services (EMS) in Sør-Trøndelag between 2018 and 2022. Incidents and patient characteristics were extracted from the Emergency Medical Communication Center (EMCC) database. In addition, data on patient characteristics and interventions for more serious incidents seen by the Helicopter Emergency Medical Service (HEMS) were included from the database LABAS. We provided descriptive statistics and estimated population incidences using Poisson regression. Results: The catchment area of EMCC Sør-Trøndelag has a population of approximately 43,000 children under the age of twelve years. During the five-year study period, there were 7005 emergency calls concerning this patient population, representing 6% of all emergency calls (total no. 108,717). Of these, 3500 (50%) resulted in the dispatch of an ambulance and/or HEMS, yielding an annual incidence of EMS dispatches of 17 per 1000 children. The three most common primary medical problems were respiratory distress, altered consciousness, and trauma. Among the 309 HEMS patients, 131 (42%) received advanced interventions from the HEMS physician. Assisted ventilation was the most frequent intervention. Conclusions: Pediatric and neonatal patients make up a small proportion of pre-hospital patient dispatches in Sør-Trøndelag. Consequently, each EMS provider infrequently encounters children in the pre-hospital environment, resulting in less experience with pediatric advanced medical interventions. This study identifies some clinical characteristics and interventions regarding pediatric and neonatal patients that have been pointed out as focus areas for pediatric pre-hospital research.

Background: Early activation of the emergency medical service (EMS) is crucial for the care of patients with STEMI. Methods: A retrospective cohort study of patients hospitalized with STEMI was conducted. Two groups of patients were compared: Bedouins and Jews. The primary outcome was one-year mortality. The secondary endpoints were 30-day mortality, mode of transportation and door-to-balloon time. Results: There were 445 Bedouin patients (BPs) and 1103 Jewish patients (JPs). BPs with STEMI were significantly younger than JPs, had more diabetes and higher rates of smoking. More JPs arrived at the hospital by ambulance compared to BPs (56.9% vs. 31.9%, p < 0.001). Direct transportation to the catheterization laboratory was observed in 51.9% of JPs and in 43.6% of BsP, p = 0.003. Door-to-balloon time was longer in BPs compared to JPs (median 65 min vs. 62 min, p = 0.044). There were no differences in one-year, 30-day and in-hospital mortality between the two groups. After adjustment by propensity score analysis for JPs vs. BPs, there was a protective factor for one-year mortality (hazard ratio (HR), 0.68; 95% CI 0.48–0.97), p = 0.034. Thirty-day and one-year mortality in the subgroup of BPs that arrived at the hospital from the outpatient clinic was higher compared to JPs (7.1% vs. 4.4%, p = 0.004 and 10.4% vs. 5.6%, p < 0.001, relatively) Conclusions: Underuse of EMS by BPs with STEMI compared to JPs resulted in a delay in direct transportation to the catheterization laboratory, longer door-to-balloon time and a higher 30-day and one-year mortality in the subgroup of BPs who arrived at the hospital after visiting an outpatient clinic.

Introduction: Emergency medical services (EMS) systems are piloting interventions to respond to overdoses with additional services such as leave‐behind naloxone and medication for opioid use disorder, but little is known about the perspectives of people who use drugs (PWUD) on these interventions being delivered by EMS during an overdose response. Methods: The Consolidated Framework for Implementation Research guided the development of data collection tools, the analytic strategy and the organisation of results. A community engaged method was used which included both academically trained researchers and community trained researchers who are also PWUD. This study used semi‐structured interviews to gather data from 13 PWUD in King County, Washington in June 2022. Data were analysed using thematic analysis. Results: The people interviewed for this study viewed EMS distribution of leave‐behind naloxone and field‐based buprenorphine favourably. They viewed EMS facilitation of hepatitis C virus and HIV testing in the field less favourably and were concerned about stigmas associated with those results. Additional themes emerged regarding: the need for different approaches to post‐overdose care; the need for new services, including post‐overdose trauma counselling and an alternative destination to the emergency department; and the harms of law enforcement presence at overdose responses. Discussion and Conclusions: This study found strong support for leave‐behind naloxone and field‐initiated buprenorphine. Further training for EMS should include trauma‐informed care and strategies to address burnout and increase compassion. Alternatives to the emergency department as a post‐overdose destination are needed. These strategies should be considered by jurisdictions revising overdose response protocols.

Ambulance-based telestroke may be a promising solution to improving stroke care. We assessed the technical feasibility and reliability of prehospital evaluations using commercial mobile phones with fifth-generation wireless communication technology. Six standardized patients portrayed scripted stroke scenarios during ambulance transport in an urban city and were remotely evaluated by independent raters using tablets (three neurologists and three emergency physicians) in a hospital, assisted by paramedics (trained in National Institute of Health Stroke Scale [NIHSS] assessment) in the ambulance; commercial cellular networks were utilized for videoconferencing transmission. The primary outcomes were mean difference (MD) and correlation of NIHSS scores between the face-to-face and remote assessments. We also examined the Bland-Altman plot for itemized NIHSS components, and Kaplan–Meier curves were used to compare the differences in the duration of the two evaluations between neurologists and emergency physicians. We conducted 32 ambulance runs and successfully completed all NIHSS examinations. No significant difference was found between the face-to-face and remote evaluations (MD, 0.782; 95% confidence interval [CI], −0.520–0.395). The correlation of NIHSS scores between the two methods was 0.994 (95% CI, 0.945–1.026), and three items exhibited the highest frequency of runs, with score differences between the two methods. There were no significant differences between neurologists and emergency physicians in the mean evaluation duration and NIHSS scores for the two methods. Prehospital evaluation using commercial mobile phones with fifth-generation wireless communication technology is feasible and reliable during ambulance transport in urban areas. Emergency physicians and neurologists performed similarly in stroke evaluations. [ABSTRACT FROM AUTHOR]

Objective: To survey the current structure, capability and operational scope of pre‐hospital and retrieval aeromedical teams across Australia. Methods: The medical directors of all Australian civilian adult aeromedical retrieval organisations with pre‐hospital teams and/or doctors for inter‐hospital critical care patient transport were contacted in a survey to qualitatively assess capacity and team structure. Results: All 17 organisations contacted completed the survey. While there is diversity in team structure with the pairing of doctors, paramedics and nurses, capacity for patient care is generally homogenous. A doctor/paramedic model is the more common team structure for rotary‐wing missions, and doctor/nurse for fixed‐wing. Differences are mostly due to state government controlled aspects of their health services. An advanced degree of intensive patient care occurs outside of the hospital. Land and sea rescue is an important aspect of Australian aeromedical work. Conclusion: Aeromedicine in Australia has many consistent elements, but variable contexts have resulted in a diversity of operational models. [ABSTRACT FROM AUTHOR]

Background. Studies have shown that the application of motorcycles in the pre-hospital emergency services in an urban environment improves the time index and the quality of services. The present study aimed to evaluate the performance of the services provided by motorlance in the Tabriz metropolis between 2018-2021. Methods. In this cross-sectional study conducted in the Tabriz pre-hospital emergency center, the recorded data about the patients using motorlance between 2018-2021 were collected and examined. The collected variables included the age, sex, chief complaint of the patients, vital signs of the patients, and final result of the mission in the pre-hospital setting. Two important indices of reaction time and response time in all the missions were evaluated. Results. A total of 9866 motorlance missions were completed during the study period. The mean reaction time was 68.24±62.91 seconds, and the mean response time was 641.70±304.48 seconds. Examination of the patients' chief complaint revealed that the lowest reaction time was for patients with abdominal pain (mean 44.90), and the lowest response time was for patients with cardiopulmonary arrest (mean 550.52). Conclusion. It was concluded that the timing indicators of motorlance missions were within the acceptable range for ambulances. Practical Implications. It was found necessary to increase the number of motorlance in metropolitan cities and employ experienced and knowledgeable personnel in motorlance in order to improve the existing situation and the quality of services.

Background: Advancement in treatment has led to prolonged survival and a rising number of women living with metastatic breast cancer (MBC) in the United States. Due to its high symptom burden, it is recommended that palliative care be integrated into the standard care to help improve quality of life. However, little is known about the use of palliative care among MBC patients in the nation. Objectives: To determine utilization of palliative care consult (PCC) after metastasis and the influence of PCC on healthcare utilization in the end of life among women living with MBC in the US. Methods: This retrospective cohort study examined a national electronic health record database to quantify the PCC use after metastasis diagnosis until death and the associations of PCC with Emergency Department (ED), Intensive Care Unit (ICU), and chemotherapies in the end-of-life women (age ≥ 18 years) living with MBC. Results: From a cohort of 2615 deceased MBC patients, 37% received PCC in the last 6 months of life. Patients who had received PCC in the end-of-life were more likely to be hospitalized, admitted to ED and ICU, and receive chemotherapies in the last 60 days before death. However, patients who had received end-of-life PCC had less hospital and ED visits and received less chemotherapies after PCC initiated. Conclusion: While PCC can reduce end-of-life aggressive interventions, it was underutilized among patients with MBC in the end-of-life. A myriad of clinical and patient factors may still challenge timely consultation. We urge for future endeavors in developing strategies to remove barriers in the implementation, especially earlier in the disease course, to assure timely PC treatments and reduce discomfort amid aggressive interventions for MBC.

INTRODUCTION: Injuries represent a widespread health problem worldwide and are the leading cause of both mortality and morbidity among children worldwide. This study examines the temporal trends of injured children transported by ambulance with the retrospective analysis of prehospital medical treatment and care. MATERIALS AND METHODS: We analysed all trauma patients transported by ambulance to the Emergency Department in the Paediatric Teaching Hospital of the University Clinical Centre of the Medical University of Warsaw in 2021. Analysis was restricted to a cohort of patients with arrival in ambulances before hospitalisation. A total of 981 patients met these criteria and were included in the analysis. Patient data was analyzed with respect of age, gender, location of the event, trauma mechanism, presence of alcohol or recreational drugs, suspicion of suicide, localisation and character of trauma, vital signs, signs and symptoms, pain assessment, treatment and procedures, and Glasgow Coma Scale (GCS) score. The relationships between the variables were examined using the dependence χ2 test, while the strength was investigated using the Cramer’s V coefficient. RESULTS: Males comprised 58% of the patient population, with a predominance in all age groups. Head trauma was the most frequently diagnosed injury. Accidents were the primary cause of injury, occurring frequently both in domestic and public settings. The specific cause of the injury varied according to the age and gender. A slightly higher volume of patients was observed on weekends and during the day compared to weekdays and regular business hours. Most of the injured children were transported by paramedic emergency medical services. Pain (66.36%) was the most prevalent symptom, followed by bleeding (18.04%). Approximately 6.12% of the patients required hospitalisation for at least 24 hours. The relationship between the child's age and the mechanism of the injuries is statistically significant [χ2 = 290,144; degrees of freedom (df) = 27; p < 0,05] and the association is medium [Cramer’s V coefficient = 0,314]. The relationship between the child's gender and the mechanism of injuries is statistically significant [χ2 = 37,844; degrees of freedom (df) = 9; p < 0,05]. CONCLUSIONS: Severe injuries in children are rare. Boys experience more injuries than girls. A significant portion of injuries occur at home. The mechanism of injury is correlated with age group and gender, but falls from height are the most common. Peak times are during the day and in the summer months, which should be taken into account for personnel planning. The improvement of the safety of children must continue.

Background/purpose: This study addresses the delicate balance between healthcare personnel burnout and medical accessibility in the context of endovascular thrombectomy (EVT) services in urban areas. We aimed to determine the minimum number of hospitals providing EVT on rotation each day without compromising patient access. Methods: Employing an optimization model, we developed shift schedules based on patient coverage rates and volumes during the pre-pandemic (2016–2018) and pandemic (2019–2021) periods. Starting with a minimum of two hospitals on duty per day, we gradually increased to a maximum of eight. Patient coverage rates, defined as the proportion of patients meeting bypass criteria and transported to rotating hospitals capable of EVT, were the primary outcomes. Sensitivity analyses explored the impact of varying patient transport intervals and accumulating patients over multiple years. Results: Results from 7024 patient records revealed patient coverage rates of 92.5% (standard deviation [SD] 2.8%) during the pre-pandemic and 91.4% (SD 2.8%) during the pandemic, with at least two rotating hospitals daily. No significant differences were observed between schedules based on the highest patient volume and coverage rate months. A patient coverage rate of 98.99% was achieved with four rotating hospitals per day during the pre-pandemic period, with limited improvement beyond this threshold. Changing patient transport intervals and accumulating patients over six years (p = 0.83) had no significant impact on coverage rates. Conclusion: Our optimization model supports reducing the number of daily rotating hospitals by half while preserving a balance between patient accessibility and alleviating strain on medical teams.

Abstract To verify if data obtained in the prehospital evaluation of patients with severe acute respiratory syndrome (SARS) during the initial response to the COVID-19 pandemic is associated with clinical outcomes: mechanical ventilation, hospital discharge, and death. This is a retrospective analysis involving secondary data from the Emergency Medical Service (EMS) records and the Health Surveillance Information System of patients assisted by the EMS in Manaus, from January to June 2020, the period of the first peak of COVID-19 cases. The combination of the two databases yielded a total of 1.190 patients, who received a first EMS response and were later admitted to hospital with SARS and had data on clinical outcomes of interest available. Patients were predominantly male (754, 63.4%), with a median age of 66 (IQR: 54.0–78.0) years. SARS illness before medical assistance was associated to need for invasive mechanical ventilation (IMV, p

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

Abstract Background Emergency medical services (EMS) personnel must rapidly assess and transport patients with time-sensitive conditions to optimise patient outcomes. Serum lactate, a valuable in-hospital biomarker, has become more accessible in EMS settings through point-of-care (POC) testing. Although POC lactate levels are valuable in specific patient groups, its broader application in EMS remains unclear. This study assessed the additional predictive value of POC lactate levels in a general adult EMS population. Methods This prospective observational study (March 2018 to September 2019) involved two EMS organisations in Västra Götaland, Sweden. Patients were triaged using the Rapid Triage and Treatment System (RETTS). POC lactate levels were measured using StatStrip Xpress devices. Non-consecutive patients who received EMS and were aged 18 years and above were available for inclusion if triaged into RETTS levels: red, orange, yellow, or green if respiratory rate of ≥ 22 breaths/min. Outcomes were adverse outcomes, including a time-sensitive diagnosis, sequential organ failure assessment (SOFA) score ≥ 2, and 30-day mortality. Statistical analyses included descriptive statistics, imputation, and regression models to assess the impact of the addition of POC lactate levels to a base model (comprising patient age, sex, presence of past medical conditions, vital signs, pain, EMS response time, assessed triage condition, and triage level) and a RETTS triage model. Results Of 4,546 patients (median age 75 [57, 84] years; 49% male), 32.4% had time-sensitive conditions, 12.5% met the SOFA criteria, and 7.4% experienced 30-day mortality. The median POC lactate level was 1.7 (1.2, 2.5) mmol/L. Patients with time-sensitive conditions had higher lactate levels (1.9 mmol/L) than those with non-time-sensitive conditions (1.6 mmol/L). The probability of a time-sensitive condition increased with increasing lactate level. The addition of POC lactate marginally enhanced the predictive models, with a 1.5% and 4% increase for the base and RETTS triage models, respectively. POC lactate level as a sole predictor showed chance-only level predictive performance. Conclusions Prehospital POC lactate assessment provided limited additional predictive value in a general adult EMS population. However, it may be beneficial in specific patient subgroups, emphasizing the need for its judicious use in prehospital settings.

The Field Assessment Stroke Triage for Emergency Destination (FAST-ED) protocol shows promise for rapid LVOS evaluation but lacks extensive validation. This study aims to assess the accuracy of FAST-ED in predicting LVOS and compare its predictive capability with the National Institute of Health Stroke Scale (NIHSS).Methods: This prospective cross-sectional study was conducted at Thammasat University Hospital. Participants included those aged 18 years or older who presented with symptoms of acute stroke syndrome within 24 hours of onset. The study focused on comparing FAST-ED assessments by emergency department physicians with NIHSS evaluations by neurologists, followed by vascular imaging, which included brain multiphase CT angiography, MRI with MRA, and transcranial Doppler ultrasound combined with carotid Doppler ultrasound. Statistical analyses included the use of AuROC to assess the effectiveness of FAST-ED and to compare FAST-ED with NIHSS.Results: 130 patients were included in the analysis, with 47 diagnosed with LVOS. No significant differences were found in most baseline characteristics between LVOS and non-LVOS groups, except for a higher prevalence of atrial fibrillation and lower systolic blood pressure in the LVOS group. The FAST-ED scale demonstrated a fair ability to predict LVOS with an AuROC of 0.79 (95% confidence interval (CI); 0.70, 0.87). A FAST-ED cut point of ≥ 4 showed improved specificity and likelihood ratio. Comparing FAST-ED≥ 4 with NIHSS≥ 6 revealed similar AuROC (0.74, 95% CI; 0.65, 0.82 and 0.72, 95% CI; 0.64, 0.80, respectively), with no significant statistical difference (p=0.661).Conclusion: FAST-ED scale, especially with a cut-off point of ≥ 4, exhibits fair overall accuracy in predicting LVOS in patients who presented with suspected acute stroke within 24 hours at the ED. This predictive capability is closely comparable to that of the NIHSS at a cut-off point of ≥ 6.Keywords: stroke, large vessel occlusion, scale, emergency medical service, emergency department

Abstract Background Prehospital management of severely burned patients is extremely challenging. It should include adequate analgesia, decision-making on the necessity of prehospital endotracheal intubation and the administration of crystalloid fluids. Guidelines recommend immediate transport to specialised burn centres when certain criteria are met. To date, there is still insufficient knowledge on the characteristics of prehospital emergency treatment. We sought to investigate the current practice and its potential effects on patient outcome. Methods We conducted a single centre, retrospective cohort analysis of severely burned patients (total burned surface area > 20%), admitted to the Berlin burn centre between 2014 and 2019. The relevant data was extracted from Emergency Medical Service reports and digital patient charts for exploratory data analysis. Primary outcome was 28-day-mortality. Results Ninety patients (male/female 60/30, with a median age of 52 years [interquartile range, IQR 37–63], median total burned surface area 36% [IQR 25–51] and median body mass index 26.56 kg/m2 [IQR 22.86–30.86] were included. The median time from trauma to ED arrival was 1 h 45 min; within this time, on average 1961 ml of crystalloid fluid (0.48 ml/kg/%TBSA, IQR 0.32–0.86) was administered. Most patients received opioid-based analgesia. Times from trauma to ED arrival were longer for patients who were intubated. Neither excessive fluid treatment (> 1000 ml/h) nor transport times > 2 h was associated with higher mortality. A total of 31 patients (34,4%) died within the hospital stay. Multivariate regression analysis revealed that non-survival was linked to age > 65 years (odds ratio (OR) 3.5, 95% CI: 1.27–9.66), inhalation injury (OR 3.57, 95% CI: 1.36–9.36), burned surface area > 60% (OR 5.14, 95% CI 1.57–16.84) and prehospital intubation (5.38, 95% CI: 1.92–15.92). Conclusion We showed that severely burned patients frequently received excessive fluid administration prehospitally and that this was not associated with more hemodynamic stability or outcome. In our cohort, patients were frequently intubated prehospitally, which was associated with increased mortality rates. Further research and emergency medical staff training should focus on adequate fluid application and cautious decision-making on the risks and benefits of prehospital intubation.

Abstract Background Emergency medical services preparedness in mass casualty incidents is one of the most important concerns in emergency systems. A mass casualty incident is a sudden event with several injured individuals that overwhelms the local health care system. This study aimed to identify and validate the components of emergency medical services readiness in mass casualty incidents which ultimately led to designing a conceptual model. Methods This research was an explanatory mixed-method study conducted in five consecutive stages in Iran between November 2021 and September 2023. First, a systematic review was carried out to extract the components of emergency medical services preparedness in mass casualty incidents based on the PRISMA guideline. Second, a qualitative study was designed to explore the preparedness components through in-depth semi-structured interviews and analyzed using the content analysis approach. Third, the integration of the components extracted from the two stages of the systematic review and qualitative study was done by an expert panel. Fourth, the obtained components were validated using the Delphi technique. Two rounds were done in the Delphi phase. Finally, the conceptual model of emergency medical services preparedness in mass casualty incidents was designed by a panel of experts. Results 10 articles were included in the systematic review stage and sixteen main components were extracted and classified into four categories. In the second stage, thirteen components were extracted from the qualitative study and classified into five categories. Then, the components of the previous two phases were integrated into the panel of experts and 23 components were identified. After validation with the Delphi technique, 22 components were extracted. Lastly, the final components were examined by the panel of experts, and the conceptual schematic of the model was drawn. Conclusions It is necessary to have an integrated framework and model of emergency medical service readiness in the planning and management of mass casualty incidents. The components and the final model of this research were obtained after the systematic scientific steps, which can be used as a scheme to improve emergency medical service preparedness in response to mass casualty incidents.

Abstract Objectives The purpose of this study was to investigate the preferred modes of transportation to the hospital among patients with acute stroke and acute myocardial infarction (AMI), as well as to identify the factors that influence the utilization of ambulances. Methods We conducted a cross-sectional study, including patients who were diagnosed with acute stroke and AMI, at the people’s hospital of Zhongjiang, from September 30th, 2022 to August 30th, 2023. All patients were divided into emergency medical service (EMS)-activation group and self-transportation group. Chi-square and t-tests were utilized to discern differences between groups at baseline. To screen relevant variables, we employed the Least Absolute Shrinkage and Selection Operator (LASSO) regression analysis using R package glmnet. Subsequently, we performed a logistic regression analysis to identify predictors of EMS activation according the results of LASSO regression. Results we collected 929 valid questionnaires. 26.16% of the patients required the services of EMS. 90.9% of individuals have not received any formal first aid education. 42.1% of them reported that they had no understanding of cardiovascular and cerebrovascular diseases. Diagnosed as AMI (OR 0.22, 95%CI 0.06 to 0.88) or acute cerebral infarction (OR 0.26, 0.10 to 0.68), the distance between the patient and the nearest 120 network hospital when the patient had these symptoms (OR 0.97, 0.94 to 0.99), the patient’s son or daughter was there when the patient was symptomatic (OR 0.58, 0.37 to 0.94), the patient (OR 0.19, 0.05 to 0.72) and the patient’s partner (wife or husband) (OR 0.36, 0.16 to 0.85) had decided that the patient needed further medical help, Among patients who did not seek immediate help after symptom onset, thinking that the symptoms will disappear spontaneously (OR 0.34, 0.13 to 0.92) or not wanting to disturb others (OR 0.06, 0.01 to 0.66) or believing that they are not important symptoms (OR 0.15, 0.05 to 0.42) were factors independently associated with less ambulance use. Age (OR 1.02, 1.00 to 1.04), Stroke patients have experienced symptoms of disturbance of consciousness or convulsions (OR 2.99, 1.72 to 5.2) were independent factors associated with increased ambulance use. Conclusion There is still ambulance underutilization among patients with acute stroke and AMI in county territory of China. Moreover, it is needed to raise the level of first aid education and awareness about EMS. Additionally, private clinic doctors and the public should gain adequate understanding of the severity of acute stroke and AMI, as well as their common symptoms, the crucial importance of prompt medical intervention. Finally, we propose that all township hospitals should be integrated into the 120 emergency networks and equipped with emergency first aid capabilities, pre-hospital care, and transportation abilities.

Background: Emergency medical personnel are among the people who play a major role in reducing the mortality and disability of the injured. This study determines the relationship between mental health and job satisfaction with professional ethics in emergency medical personnel. Materials and Methods: The present cross-sectional study included 126 emergency medical personnel in Hamadan City, Iran. The data were collected using a 3-part demographic information questionnaire, the 28-item general health questionnaire, the Barry Field and Ruth job satisfaction questionnaire and the Cadozier professional ethics questionnaire. The data were analyzed using Stata software, version 14. Meanwhile, the significance level was considered P

Background: Undoubtedly, overlooking a stroke can result in severe disability or even death. However, identifying stroke patients in the prehospital setting poses a significant challenge. While the Face–Arm–Speech–Time (FAST) score is widely used, its effectiveness has been questioned because of its focus on symptoms primarily associated with anterior circulation strokes. In response to this limitation, we developed the innovative FAST4D score and conducted a comparative analysis of stroke detection rates between the novel FAST4D score and the FAST score. Methods: This prospective, multicenter proof-of-concept study aimed to assess stroke detection rates using both the FAST score and the new FAST4D score, which incorporates additional items such as the acute onset of diplopic images, deficit in the field of vision, dizziness/vertigo, and dysmetria/ataxia. Following their presentation to emergency medical services, all patients suspected of having a stroke and those diagnosed with a stroke upon discharge were included in this study. The diagnostic performance of the novel FAST4D score was evaluated and compared with that of the FAST score. Results: Between May 2019 and June 2021, a total of 1469 patients (749 female) were enrolled, with 1035 patients discharged with the diagnosis of stroke. Notably, 259 patients were identified solely through the FAST4D score. This resulted in a significantly higher rate of correctly identified as having had a stroke (stroke detection rate, sensitivity) with the new FAST4D score (93%) compared with the established FAST score (78%) (p < 0.001). This resulted in a reduction in false negative diagnoses by 65%. Conclusions: The novel FAST4D score demonstrated a 15-percentage increase in the stroke detection rate. This heightened detection rate holds the potential for more accurate patient allocation to stroke units, consequently reducing the time to revascularization. [ABSTRACT FROM AUTHOR]

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

This study addresses the delicate balance between healthcare personnel burnout and medical accessibility in the context of endovascular thrombectomy (EVT) services in urban areas. We aimed to determine the minimum number of hospitals providing EVT on rotation each day without compromising patient access. Employing an optimization model, we developed shift schedules based on patient coverage rates and volumes during the pre-pandemic (2016–2018) and pandemic (2019–2021) periods. Starting with a minimum of two hospitals on duty per day, we gradually increased to a maximum of eight. Patient coverage rates, defined as the proportion of patients meeting bypass criteria and transported to rotating hospitals capable of EVT, were the primary outcomes. Sensitivity analyses explored the impact of varying patient transport intervals and accumulating patients over multiple years. Results from 7024 patient records revealed patient coverage rates of 92.5% (standard deviation [SD] 2.8%) during the pre-pandemic and 91.4% (SD 2.8%) during the pandemic, with at least two rotating hospitals daily. No significant differences were observed between schedules based on the highest patient volume and coverage rate months. A patient coverage rate of 98.99% was achieved with four rotating hospitals per day during the pre-pandemic period, with limited improvement beyond this threshold. Changing patient transport intervals and accumulating patients over six years (p = 0.83) had no significant impact on coverage rates. Our optimization model supports reducing the number of daily rotating hospitals by half while preserving a balance between patient accessibility and alleviating strain on medical teams.

INTRODUCTION: Injuries represent a widespread health problem worldwide and are the leading cause of both mortality and morbidity among children worldwide. This study examines the temporal trends of injured children transported by ambulance with the retrospective analysis of prehospital medical treatment and care. MATERIALS AND METHODS: We analysed all trauma patients transported by ambulance to the Emergency Department in the Paediatric Teaching Hospital of the University Clinical Centre of the Medical University of Warsaw in 2021. Analysis was restricted to a cohort of patients with arrival in ambulances before hospitalisation. A total of 981 patients met these criteria and were included in the analysis. Patient data was analyzed with respect of age, gender, location of the event, trauma mechanism, presence of alcohol or recreational drugs, suspicion of suicide, localisation and character of trauma, vital signs, signs and symptoms, pain assessment, treatment and procedures, and Glasgow Coma Scale (GCS) score. The relationships between the variables were examined using the dependence χ2 test, while the strength was investigated using the Cramer's V coefficient. RESULTS: Males comprised 58% of the patient population, with a predominance in all age groups. Head trauma was the most frequently diagnosed injury. Accidents were the primary cause of injury, occurring frequently both in domestic and public settings. The specific cause of the injury varied according to the age and gender. A slightly higher volume of patients was observed on weekends and during the day compared to weekdays and regular business hours. Most of the injured children were transported by paramedic emergency medical services. Pain (66.36%) was the most prevalent symptom, followed by bleeding (18.04%). Approximately 6.12% of the patients required hospitalisation for at least 24 hours. The relationship between the child's age and the mechanism of the injuries is statistically significant [χ2 = 290,144; degrees of freedom (df) = 27; p < 0,05] and the association is medium [Cramer's V coefficient = 0,314]. The relationship between the child's gender and the mechanism of injuries is statistically significant [χ2 = 37,844; degrees of freedom (df) = 9; p < 0,05]. CONCLUSIONS: Severe injuries in children are rare. Boys experience more injuries than girls. A significant portion of injuries occur at home. The mechanism of injury is correlated with age group and gender, but falls from height are the most common. Peak times are during the day and in the summer months, which should be taken into account for personnel planning. The improvement of the safety of children must continue. [ABSTRACT FROM AUTHOR]

During and subsequent to a natural disaster, there is an expectation that certain elements of society will continue to operate with a degree of normalcy. For example, it is expected that emergency medical services will continue to function and remain reliable for the community served. Expectations such as these are based on the presumed reliability of government and the assumption that those responsible for the relevant infrastructure will have made plans to ensure it remains functional and taken steps to mitigate known weaknesses. The COVID-19 pandemic provides a case in point. Specifically, data captured during the pandemic are now the subject of ongoing review and analysis, and the findings from such studies are being used to inform planning and preparedness for the next public health disaster. This particular study was conducted in response to circumstantial evidence indicating that frontline workers in the healthcare profession may share some of the same ambivalence towards transmission mitigation as seen in the general population when confronted with new and emerging communicable diseases. This is a concern, as when medical personnel are either unable or unwilling to take reasonable steps to protect themselves and their patients, it undermines the readiness of the essential service. To explore this situation in greater depth, the study examines the real-time responses from a sample of frontline personnel interviewed during the pandemic. The results indicate that there are a number of opportunities to improve workforce readiness to assure reliable continuity during the next outbreak, epidemic or pandemic. [ABSTRACT FROM AUTHOR]

Background: Emergency medical services (EMS) personnel must rapidly assess and transport patients with time-sensitive conditions to optimise patient outcomes. Serum lactate, a valuable in-hospital biomarker, has become more accessible in EMS settings through point-of-care (POC) testing. Although POC lactate levels are valuable in specific patient groups, its broader application in EMS remains unclear. This study assessed the additional predictive value of POC lactate levels in a general adult EMS population. Methods: This prospective observational study (March 2018 to September 2019) involved two EMS organisations in Västra Götaland, Sweden. Patients were triaged using the Rapid Triage and Treatment System (RETTS). POC lactate levels were measured using StatStrip Xpress devices. Non-consecutive patients who received EMS and were aged 18 years and above were available for inclusion if triaged into RETTS levels: red, orange, yellow, or green if respiratory rate of ≥ 22 breaths/min. Outcomes were adverse outcomes, including a time-sensitive diagnosis, sequential organ failure assessment (SOFA) score ≥ 2, and 30-day mortality. Statistical analyses included descriptive statistics, imputation, and regression models to assess the impact of the addition of POC lactate levels to a base model (comprising patient age, sex, presence of past medical conditions, vital signs, pain, EMS response time, assessed triage condition, and triage level) and a RETTS triage model. Results: Of 4,546 patients (median age 75 [57, 84] years; 49% male), 32.4% had time-sensitive conditions, 12.5% met the SOFA criteria, and 7.4% experienced 30-day mortality. The median POC lactate level was 1.7 (1.2, 2.5) mmol/L. Patients with time-sensitive conditions had higher lactate levels (1.9 mmol/L) than those with non-time-sensitive conditions (1.6 mmol/L). The probability of a time-sensitive condition increased with increasing lactate level. The addition of POC lactate marginally enhanced the predictive models, with a 1.5% and 4% increase for the base and RETTS triage models, respectively. POC lactate level as a sole predictor showed chance-only level predictive performance. Conclusions: Prehospital POC lactate assessment provided limited additional predictive value in a general adult EMS population. However, it may be beneficial in specific patient subgroups, emphasizing the need for its judicious use in prehospital settings. [ABSTRACT FROM AUTHOR]

Background: Prehospital management of severely burned patients is extremely challenging. It should include adequate analgesia, decision-making on the necessity of prehospital endotracheal intubation and the administration of crystalloid fluids. Guidelines recommend immediate transport to specialised burn centres when certain criteria are met. To date, there is still insufficient knowledge on the characteristics of prehospital emergency treatment. We sought to investigate the current practice and its potential effects on patient outcome. Methods: We conducted a single centre, retrospective cohort analysis of severely burned patients (total burned surface area > 20%), admitted to the Berlin burn centre between 2014 and 2019. The relevant data was extracted from Emergency Medical Service reports and digital patient charts for exploratory data analysis. Primary outcome was 28-day-mortality. Results: Ninety patients (male/female 60/30, with a median age of 52 years [interquartile range, IQR 37–63], median total burned surface area 36% [IQR 25–51] and median body mass index 26.56 kg/m2 [IQR 22.86–30.86] were included. The median time from trauma to ED arrival was 1 h 45 min; within this time, on average 1961 ml of crystalloid fluid (0.48 ml/kg/%TBSA, IQR 0.32–0.86) was administered. Most patients received opioid-based analgesia. Times from trauma to ED arrival were longer for patients who were intubated. Neither excessive fluid treatment (> 1000 ml/h) nor transport times > 2 h was associated with higher mortality. A total of 31 patients (34,4%) died within the hospital stay. Multivariate regression analysis revealed that non-survival was linked to age > 65 years (odds ratio (OR) 3.5, 95% CI: 1.27–9.66), inhalation injury (OR 3.57, 95% CI: 1.36–9.36), burned surface area > 60% (OR 5.14, 95% CI 1.57–16.84) and prehospital intubation (5.38, 95% CI: 1.92–15.92). Conclusion: We showed that severely burned patients frequently received excessive fluid administration prehospitally and that this was not associated with more hemodynamic stability or outcome. In our cohort, patients were frequently intubated prehospitally, which was associated with increased mortality rates. Further research and emergency medical staff training should focus on adequate fluid application and cautious decision-making on the risks and benefits of prehospital intubation.

Heatwaves are periods of unusual heat, whose frequency and intensity is increasing. Heatwaves also translate into emergency healthcare dysfunctions, but evidence on how to mitigate these effects still needs to be provided. This multicentric study aimed to identify the interactions between heatwaves and prehospital emergency medicine (PHEM). After obtaining informed consent, PHEM personnel working full-time in different districts of the Veneto Region, Northern Italy, were recruited. Their perspective was captured through semi-structured interviews and analyzed using content analysis methodology. Thirteen subjects participated in the study. Their insights were categorized into four themes: perception of heatwaves; clinical impact of heatwaves; social factors and heatwaves; heatwaves and emergency medical service (EMS). According to the interviewees, the strain on EMSs during heatwaves may be partially reduced by interventions targeting vulnerable populations, primary care, social networks, and education and information. Specific public health actions could follow the surge science principles of staff, stuff, structure, and system to help policymakers improve EMS surge capacity planning, preparedness, and responses. The present study also identified PHEM vulnerabilities and targets of interventions to implement heat–health action plans, mitigate the risk of prehospital emergency care dysfunction, and improve EMS sustainability and preparedness against heatwaves and the changing climate.

Pre-hospital emergency medical service (PHEMS) is critical for the treatment outcomes of life-threatening injuries and time-sensitive illnesses. Response time, influenced by traffic conditions and the site planning of pre-hospital emergency medical facilities (PHEMFs), is the main indicator for evaluating PHEMS. In 2020, the Beijing government released the "Special Plan for Spatial Layout of Pre-hospital Emergency Medical Facilities in Beijing (2020–2022)". This paper evaluates the functional efficiency and spatial equity of this plan within Beijing's central six districts using isochrone measures to assess the accessibility of the planned PHEMFs. The isochrone coverages of the area and population were calculated, and the temporal-spatial characteristics of isochrones were concluded. The analysis revealed that while the current planning meets several objectives, challenges in service availability and equity persist. Although 10-min isochrone coverage was high, 8-min coverage was insufficient, particularly during peak hours. This highlights gaps in service accessibility that necessitate additional emergency stations in underserved areas. The current planning approach leads to significant overlap at administrative boundaries, causing service oversupply and increased costs, which calls for a city-wide planning perspective that breaks administrative boundaries to optimize resource allocation. Traffic conditions significantly impact service coverage, with congestion reducing coverage in central areas and better coverage near traffic hubs. Future planning should strategically place stations based on traffic patterns and population distribution to enhance emergency medical service accessibility and equity in urban areas.

Background: Point-of-care ultrasound (POCUS) is steadily growing in use in prehospital emergency medicine. While currently used primarily by emergency physicians, POCUS could also be employed by paramedics to support diagnosis and decision-making. Yet to date, no paramedicine-targeted POCUS curricula exist in Germany. Furthermore, given time and resource constraints in paramedic training, it is unclear whether paramedics could feasibly learn POCUS for prehospital deployment. Hence, this study outlines the development and implementation of a comprehensive POCUS curriculum for paramedics. Through this curriculum, we investigate whether paramedics can attain proficiency in POCUS comparable to other user groups. Methods: In this prospective observational study, we first developed a blended learning-based POCUS curriculum specifically for paramedics, focusing on basic principles, the RUSH-Protocol and ultrasound guided procedures. Participants underwent digital tests to measure their theoretical competence before (T1) and after the digital preparation phase (T2), as well as at the end of the on-site phase (T3). At time point T3, we additionally measured practical competence using healthy subjects and simulators. We compared the theoretical competence and the practical competence on a simulator with those of physicians and medical students who had also completed ultrasound training. Furthermore, we carried out self-assessment evaluations, as well as evaluations of motivation and curriculum satisfaction. Results: The paramedic study group comprised n = 72 participants. In the theoretical test, the group showed significant improvement between T1 and T2 (p < 0.001) and between T2 and T3 (p < 0.001). In the practical test on healthy subjects at T3, the group achieved high results (87.0% ± 5.6). In the practical test on a simulator at T3, paramedics (83.8% ± 6.6) achieved a lower result than physicians (p < 0.001), but a comparable result to medical students (p = 0.18). The results of the study group's theoretical tests (82.9% ± 9.2) at time point T3 were comparable to that of physicians (p = 0.18) and better than that of medical students (p < 0.01). The motivation and attitude of paramedics towards the prehospital use of POCUS as well as their self-assessment significantly improved from T1 to T3 (p < 0.001). The overall assessment of the curriculum was positive (92.1 ± 8.5). Conclusion: With our tailored curriculum, German paramedics were able to develop skills in POCUS comparable to those of other POCUS learners. Integration of POCUS into paramedics' training curricula offers opportunities and should be further studied. [ABSTRACT FROM AUTHOR]

Background: Emergency medical services preparedness in mass casualty incidents is one of the most important concerns in emergency systems. A mass casualty incident is a sudden event with several injured individuals that overwhelms the local health care system.

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

Background: Emergency medical personnel are among the people who play a major role in reducing the mortality and disability of the injured. This study determines the relationship between mental health and job satisfaction with professional ethics in emergency medical personnel. Materials and Methods: The present cross-sectional study included 126 emergency medical personnel in Hamadan City, Iran. The data were collected using a 3-part demographic information questionnaire, the 28-item general health questionnaire, the Barry Field and Ruth job satisfaction questionnaire and the Cadozier professional ethics questionnaire. The data were analyzed using Stata software, version 14. Meanwhile, the significance level was considered P<0.05. Results: Most of the participants in the study were married (53.17%), technicians (80.95%), in contractual employment (75.4%), with rotating shift type (84.92%), had a bachelor's degree (55.56%) and were not satisfied with their monthly income (76.98%). The results showed that the mean scores of mental health, professional ethics and job satisfaction were 50.9, 81.45 and 35.58, respectively. There is a direct and significant relationship between mental health and professional ethics (P=0.007, r=0.24). Additionally, there is a direct and significant relationship between professional ethics and job satisfaction (P=0.001, r=0.41). However, no significant relationship was observed between mental health and job satisfaction (P=0.24, r=0.10). Conclusion: Mental health workshops and fun facilities can improve emergency medical personnel's professional ethics and job satisfaction due to their direct relationship. [ABSTRACT FROM AUTHOR]

Background: Homeless individuals are vulnerable and have a higher burden of illness. Barriers to care exist and experiences can be negative, contributing to increased morbidity and mortality. The experiences of homeless individuals accessing healthcare through ambulance services is underexplored. Aims: The study aims to describe why homeless individuals access healthcare through ambulance services and identify lived experiences. Methods: A narrative literature review was undertaken using Preferred Reporting Items for Systematic Reviews and Meta-Analyses methodology, with Critical Appraisal Skills Programme tools used to assess quality before thematic synthesis. Results: Twenty-three studies were included. Six themes were identified including frequency of ambulance use and clinical characteristics, why healthcare is accessed through ambulance services and the experiences of homeless individuals and paramedics. Conclusions: Evidence relating to homeless individuals accessing healthcare through ambulance services is limited. However, it is clear this group uses these services more often than non-homeless individuals, likely because of their higher chronic illness burden. Services should be developed to meet the needs of homeless individuals and to help ensure demand on ambulance services is manageable and affordable. [ABSTRACT FROM AUTHOR]

Aims: The PIVOT trial evaluates the clinical outcomes and ventilatory quality of an automatic pneumatic ventilation method compared to a bag-valve-mask ventilation method in patients who have experienced out-of-hospital cardiac arrest and have had an advanced airway placed. Methods: The PIVOT trial is a pragmatic, open-label, multicenter randomized controlled trial. It aims to recruit 514 patients in Hsinchu County, Taiwan. Adult, non-trauma patients who experience out-of-hospital cardiac arrest, are treated by emergency medical services, and have an advanced airway in place will be randomized. Biweekly cluster randomization will assign EMS teams to either the automatic pneumatic ventilation group or the bag-valve-mask group. Informed consent is waived. The primary outcome is the return of spontaneous circulation, either prehospital or in-hospital. Secondary outcomes include survival to discharge, neurological outcomes, prehospital ventilatory quality, and the content of prehospital resuscitation. Participants will be followed until they pass away or are discharged from the hospital. Conclusion: The PIVOT trial will provide new insight on the clinical effectiveness of automatic pneumatic ventilation in patients experienced out-of-hospital cardiac arrest.Trial number: NCT06067204 in clinicaltrial.gov

IntroductionEmergency medical service (EMS) serves as a pivotal role in linking injured road users to hospitals via offering first aid measures and transportation. This paper aims to investigate the effect of emergency medical service (EMS) response time on the fatality risk of freeway crashes.MethodsCrash injury severity data from Kaiyang Freeway, China in 2014 and 2015 are employed for the empirical investigation. A Bayesian random parameters spatial logistic model is developed for analyzing crash severity.ResultsBayesian inference of the random parameters spatial logistic model demonstrates the importance of reducing EMS response time on minimizing the fatality risk of freeway crashes. Fatality odds would increase by 2.6% for 1 min increase in EMS response time. Additionally, vehicle type, crash type, time of day, horizontal curvature, vertical grade, and precipitation are also found to have significant effects on the fatality probability of freeway crashes.ConclusionIt is crucial to reduce EMS response time to decrease the fatality likelihood of freeway crashes. Some countermeasures have been proposed to shorten EMS response time.

Abstract Background Emergency medical service providers are frequently exposed to a variety of stressors as a result of their work environment. These stressors can have detrimental effects on both the physical and mental well-being of individuals. This study was conducted with the aim of exploring stress management strategies in emergency medical service providers. Methods This study was conducted in 2023 using a qualitative approach and content analysis method. A purposive sampling method was used to include 16 emergency medical system providers from Hamadan city. Semi-structured interviews, with a duration of 45–60 min, were conducted for data collection. The Data were analyzed using Graneheim and Lundman’s conventional content analysis approach. Results The analysis of the interview data revealed three themes: readiness for the worst conditions, assistance based on supportive partnerships, and striving for balance. The six categories within these three themes were mental preparation, risk management, collaborations in emergency response, supportive communication, adaptive behaviors, and maladaptive responses. Conclusions The results of this study shed light on the various stress management strategies employed by emergency medical service providers. Understanding and implementing effective stress management strategies can not only enhance the well-being of emergency medical service providers but also improve the quality of patient care. Further research and action are essential to promote the resilience and mental health of these professionals, ensuring their overall well-being and job satisfaction.

Abstract Background Almost all paramedics encounter workplace violence (WPV) during their careers. The most common form of WPV is verbal, and the perpetrator is usually the patient. It is known that paramedics suffer from post-traumatic stress disorder and other mental health problems, and WPV is one of the reasons behind that. Nevertheless, little is known about the recovery processes paramedics have had after encountering WPV. The research question was: What kind of recovery processes have paramedics had after encountering WPV? Methods A qualitative, narrative interview study was done. Data was collected in individual interviews with Finnish paramedics (n = 18). Paramedics were from different parts of Finland, and their ages varied from 24 to 49 years. They had been working in EMS for an average of 10.5 years (range 1.5 to 25 years). Interviews were conducted with a narrative approach, which enabled paramedics to narrate their experiences and speak on their own terms about the subject to the extent of their choosing. The data was analyzed using thematic analysis. Results Ten recovery process themes were identified: Strong psychological and physical reactions in a short time frame, Questioning one’s profession and actions, Various support structures aided in recovery, Dysfunctional processes hindered recovery, Personal resources provided support, The support of the workcommunity as a lifeline, Left to cope alone, Permanent changes to work routines, Resulting in professional growth and Eternal crack in the shell. Conclusions Many internal and external factors affect paramedics’ recovery processes. While some receive adequate help, others struggle to get appropriate support, especially from their organization and supervisors. The findings of this study suggest that clear protocols should be established to help paramedics recover after encountering WPV and that an individual aspect should be kept in mind, as not everybody reacts in the same way.

Abstract Background Procedural sedation and analgesia (PSA) is a technique of administering sedatives to induce a state that allows the patient to tolerate painful procedures while maintaining cardiorespiratory function, a condition that is frequently desired prehospital. Non-physician prehospital clinicians often have a limited scope of practice when it comes to providing analgesia and sedation; sometimes resulting in a crew request for back-up from physician-staffed prehospital services.“. This is also the case if sedation is desirable. Advanced practice providers (APPs), who are legally authorized and trained to carry out this procedure, may be a solution when the physician-staffed service is not available or will not be available in time. Methods The aim of this study is to gain insight in the circumstances in which an APP, working at the Dutch ambulance service “RAV Brabant MWN” from January 2019 to December 2022, uses propofol for PSA or to provide sedation. With this a retrospective observational document study we describe the characteristics of patients and ambulance runs and evaluates the interventions in terms of safety. Results During the study period, the APPs administered propofol 157 times for 135 PSA and in 22 cases for providing sedation. The most common indication was musculoskeletal trauma such as fracture care or the reduction of joint dislocation. In 91% of the situations where propofol was used, the predetermined goal e.g. alignment of fractured extremity, repositioning of luxated joint or providing sedation the goal was achieved. There were 12 cases in which one or more adverse events were documented and all were successfully resolved by the APP. There were no cases of laryngospam, airway obstruction, nor anaphylaxis. None of the adverse events led to unexpected hospitalization or death. Conclusion During the study period, the APPs performed 135 PSAs and provided 22 sedations. The success rate of predetermined goals was higher than that stated in the literature. Although there were a number of side effects, their incidences were lower than those reported in the literature, and these were resolved by the APP during the episode of care. Applying a PSA by an APP at the EMS “RAV Brabant MWN” appears to be safe with a high success rate.

Background/purpose: This review aimed to investigate the effect of crew ratios of on-scene advanced life support (ALS)-trained personnel on patients with out-of-hospital cardiac arrest (OHCA). Methods: We systematically searched PubMed, Ovid EMBASE, and the Cochrane Central Register of Controlled Trials databases from the inception date until September 30, 2022, for eligible studies. Two reviewers independently screened the studies for relevance, extracted data, and quality. We compared the effect of the ratio of on-scene ALS-trained personnel >50 % to those with a ratio ≤50 % among prehospital personnel on the clinical outcomes of OHCA patients. The primary outcome was survival-to-discharge and secondary outcomes were any return of spontaneous circulation (ROSC), sustained ROSC (≥2 h), and favourable neurological outcome at discharge (cerebral performance category scores: 1 or 2). Pooled odds ratios (ORs) were calculated, and the certainty of evidence was assessed. Results: From 10,864 references, we identified four non-randomised studies, including 16,475 patients. Two studies were performed in Japan and two in Taiwan. There were significant differences in survival-to-discharge (OR: 1.24, 95 % confidence interval [CI]: 1.07–1.44, I2: 7 %), any ROSC (OR:1.22, 95 % CI: 1.04–1.43, I2: 74 %) and sustained ROSC (OR: 1.39, 95 % CI: 1.16–1.65, I2: 40 %), but insignificant differences in favourable neurological outcome at discharge. The overall certainty of evidence was rated as very low for all outcomes. Conclusion: Prehospital ALS care with a ratio of on-scene ALS-trained personnel >50 % could improve OHCA patient outcomes than crew ratios ≤50 %. Further studies are required to reach a robust conclusion.

This study aimed to identify event-related factors in OHCA and their impact on return of spontaneous circulation (ROSC) achievement and maintenance until hospital admission.Patients and Methods: All data were collected from Utstein Resuscitation Registry Template for OHCA from The Institute of Emergency Medicine of Zagreb from January 2012 to August 2022. This cross-sectional research analyzed 2839 Utstein reports, including 2001 male, 836 female, and 8 subjects of unknown gender. The average age was 65.4 ± 16.2 years.Results: The most frequent place of collapse was private residence, and 27% of collapses were unwitnessed. Dispatcher-provided CPR instructions were provided in 39.7% of cases until the arrival of the emergency service team, which showed a very strong effect on bystander-provided CPR, and were followed in 68.4% of cases, while non-instructed bystander CPR was provided in only 7.9% of cases. Bystander CPR is more likely to be provided in public places than in private residences, often with both compression and ventilation. Bystander CPR was also more likely to be provided to men. Cases with bystander CPR, and compressions with ventilation compared to compression only CPR, showed a significantly greater success in maintaining ROSC later in CPR, both with moderate effects.Conclusion: Bystander CPR has been shown to have a significant role in achieving and maintaining ROSC until hospital admission. However, our results showed a location-dependent nature of bystanders’ willingness to perform CPR as well as sex disparities in patients receiving CPR. With deficient education in basic life support in Croatia, dispatchers need to insist on and instruct bystander CPR performance.Keywords: out-of-hospital cardiac arrest, cardiopulmonary resuscitation, emergency medical service
