Abstract Background Family presence during resuscitation is a controversial issue worldwide. The aim of this study was to investigate the self-confidence and attitudes of Emergency Medical Technicians (EMTs) towards family presence during resuscitation (FPDR). Methods In this cross-sectional study, a random sample of 252 EMTs were selected from 110 prehospital emergency centers. Two main questionnaires were used to collect data on the EMTs’ self-confidence and attitudes towards FPDR. Results The results showed that the EMTs’ attitudes towards FPDR were lower than the mean (43.69 ± 19.40). In addition, more than 85% of them stated that the resuscitation process was stressful for the patient’s companions. There was a positive correlation between EMTs’ self-confidence and attitudes towards FPDR (r = 0.52, p

High temperatures are linked to an increase in heat-related illnesses, which have significantly impacted the public health system, particularly emergency medical services (EMS). Analyzing the pattern of heat-related illness cases in EMS can improve resource utilization and preparedness within the public health system.Patients and Methods: A retrospective study was conducted on EMS data from Srinagarind Hospital, Thailand, covering the summer months (February to May) from 2020 to 2024. Patients with heat-related illnesses were identified in the EMS database using the 10th revision of the International Classification of Diseases (ICD-10) version 2019, specifically codes under “T67 Effects of Heat and Light”, which include heat stroke, heat syncope, heat cramps, heat exhaustion, and heat fatigue.Results: A total of 136 EMS operations from the hospital’s database were analyzed. In the summer 2024 group, 95.7% (N=44) of the patients were male. The majority of EMS triage cases required resuscitation (P = 0.020). Outdoor activity was identified as a significant factor related to heat illness, with rates of 83.3%, 92.9%, 93.3%, 97.1%, and 93.5% over the five years of the study. The activation time was 1.30 minutes for the summer of 2024 and 1.24 minutes for the summer of 2023. Notably, the average scene time in the summer 2024 group was significantly longer at 25.2 minutes, compared to 12.0 minutes in the summer 2020 group (P< 0.001).Conclusion: Outdoor activity was the most significant risk factor associated with increased heat-related illnesses. Other contributing factors included male gender, age between 20– 40 years, scene temperatures above 35°C, and prolonged scene times exceeding 15 minutes.Keywords: global warming, healthcare policy, heat illness, prehospital emergency care

Abstract Background Violence against Emergency Medical Services (EMS) personnel vary between studies. Current studies are mainly based on self-reporting, thus other designs are needed to provide more perspective. The purpose of this study was to explore the rate and predictors of violent behavior targeted at EMS personnel by exploring the Electronic patient care records (ePCR) documentation by EMS personnel. Methods This was a retrospective cohort study of EMS patients in Finland. The data were collected from three regions between 1st June and 30th November 2018. Text mining and manual evaluation were used to identify and explore predictors of violence targeted at EMS personnel from the ePCR narratives. Multivariable logistic regressions were used to determine factors that were independently associated with violent behavior. The results are presented with odds ratios (ORs) with 95% confidence intervals (CIs). Results The EMS personnel reported experiences of violence in a total of 297 identified missions (0.7%) of all EMS missions (n = 40,263). The violence was mostly verbal (62.3%) and the most common violence perpetrator was the patient (98.0%). The police were alarmed to many missions where violence was reported (40.7%). Sometimes violence occurred suddenly although the police were present. The multivariable logistic regression model indicates that violence occurred typically in urban areas (OR 1.699; 95% CI 1.283 to 2.248), at weekend nights (OR 1.357; 95% CI 1.043 to 1.765), by male (OR 1.501; 95% CI 1.160 to 1.942), and patients influenced by alcohol (OR 3.464; 95% CI 2.644 to 4.538). A NEWS2 score of 3 in any parameter (vs. score 0–4, OR 2.386; 95% CI: 1.788 to 3.185) and ALS unit type (vs. BLS, OR 1.373; 95% CI: 1.009 to 1.866) increased the likelihood as well. Conclusions The documentation in ePCRs show low rates of violence targeted at EMS personnel. However, violence is a multidimensional phenomenon connected to unfamiliar patients, rushed situations, and an uncontrolled environment. This means that the EMS personnels’ safety cannot be ensured in all situations. Therefore, a balance between safety margins and treating patients needs to be considered.

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.

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 In patients with out‐of‐hospital cardiac arrest (OHCA) who attain return of spontaneous circulation (ROSC), rearrest while in the prehospital setting represents a significant barrier to survival. To date, there are limited data to guide prehospital emergency medical services (EMS) management immediately following successful resuscitation resulting in ROSC and prior to handoff in the emergency department. Post‐ROSC care encompasses a multifaceted approach including hemodynamic optimization, airway management, oxygenation, and ventilation. We sought to develop an evidenced‐based, goal‐directed bundle of care targeting specified vital parameters in the immediate post‐ROSC period, with the goal of decreasing the incidence of rearrest and improving survival outcomes. Here, we describe the rationale and development of this goal‐directed bundle of care, which will be adopted by several EMS agencies within California. We convened a group of EMS experts, including EMS Medical Directors, quality improvement officers, data managers, educators, EMS clinicians, emergency medicine clinicians, and resuscitation researchers to develop a goal‐directed bundle of care to be applied in the field during the period immediately following ROSC. This care bundle includes guidance for prehospital personnel on recognition of impending rearrest, hemodynamic optimization, ventilatory strategies, airway management, and diagnosis of underlying causes prior to the initiation of transport.

Aim: This study aims to identify the organizational climate and culture among nurses working in Immediate Life Support Ambulances (ILSA). Methods: A descriptive, quantitative, and cross-sectional study was conducted with 81 Portuguese nurses working in Immediate Life Support Ambulances at the National Medical Emergency Institute (INEM). The data was analyzed using the Principal Component Analysis (PCA) method, followed by a Varimax rotation, and the models were validated using the Kaiser-Meyer-Olkin test and Bartlett’s test of sphericity. Findings: Factorial analysis yielded four factors, namely: Support (24.5%), Objectives (13.6%), Rules (9.7%), and Innovation (8.01%), associated with organizational climate and culture. Nurses with an undergraduate degree perceived significantly more support than those with higher qualifications. Support also varied according to relationship status, revealing that married nurses had a higher perception than those cohabiting. Conclusion: Organizational climate and culture unequivocally contribute to developing a healthy and safe work environment and are decisive for the quality of nursing care.

Objective: Traumatic brain injury (TBI) is among the leading causes of death and disability globally. Identifying and assessing the risk of in-hospital mortality in traumatic brain injury patients at an early stage is challenging. This study aimed to develop a model for predicting in-hospital mortality in TBI patients using prehospital data from China. Methods: We retrospectively included traumatic brain injury patients who sustained injuries due to external forces and were treated by pre-hospital emergency medical services (EMS) at a tertiary hospital. Data from the pre-hospital emergency database were analyzed, including demographics, trauma mechanisms, comorbidities, vital signs, clinical symptoms, and trauma scores. Eligible patients were randomly divided into a training set (241 cases) and a validation set (104 cases) at a 7:3 ratio. Least absolute shrinkage and selection operator (LASSO) and multivariate logistic regression were employed to identify independent risk factors. Analyzed the discrimination, calibration, and net benefit of the nomogram across both groups. Results: 17.40 % (42/241) of TBI patients died in the hospital in the training set, while 18.30 % (19/104) in the validation set. After analysis, chest trauma (odds ratio [OR] = 4.556, 95 % confidence interval [CI] = 1.861–11.152, P = 0.001), vomiting (OR = 2.944, 95%CI = 1.194–7.258, P = 0.019), systolic blood pressure (OR = 0.939, 95%CI = 0.913–0.966, P

Background: Due to the nature of their work, prehospital personnel face various ethical challenges that can lead to moral distress. Compared to hospital nurses, the interaction of personnel in the pre-hospital environment is closer, and the ethical climate can affect the reaction of pre-hospital personnel in the face of moral challenges and distress. This study determines the relationship between moral distress and ethical climate among prehospital personnel. Materials and Methods: This cross-sectional correlational study was conducted on 136 emergency medical services personnel selected via census sampling. To collect the data, two instruments were used, namely the revised moral distress and Victor and Cullen’s standard ethical climate. The data were analyzed using descriptive statistics and Pearson correlation in the SPSS software, version 23. Results: According to the results, the mean score of moral distress intensity (MDI) was high (3.65±1.14) and the mean score of moral distress frequency (MDF) was moderate (1.83±0.53) among emergency medical services personnel. The mean ethical climate was moderate (2.96±1.02). The study found a negative and significant relationship between ethical climate and MDI among emergency medical services staff (r=-0.34, P0.05). This study also found a significant relationship between MDI and personal characteristics, such as age, work experience, and history of referral to the board of inquiry (P0.05). Conclusion: Considering the positive effect of the ethical climate on reducing emergency medical services providers’ moral distress, more attention is essential to the factors affecting moral distress.

Abstract Background Skydiving is the fastest nonmotorized sport; and consequently is not without risk. In the last decades, skydiving has become considerably safer but injuries and fatalities still occur. Incidents are reported to and administered by the Royal Netherlands Aeronautical Association (KNVvL). From 1995 to 2020, 2715 incidents were reported; of which 1503 resulted in injury and 26 in fatality. There is a need for more information available on the particular type, severity, and factors which contribute to skydiving-related injuries worldwide. This study aims to investigate patterns in occurrence rates, examine demographic and skydiving-related factors linked to injuries, and analyze the types and severity of injuries relating to these contributing factors. Methods The Dutch KNVvL database – covering more than 25 years of data – was examined for contributing factors. An analysis of the severity and types of injury resulting from incidents over the last five years were matched with a search of hospital databases. Results The rate of injuries pattern increases starting from 2016, with novice jumpers having the highest risk of injury. Most injuries occur during the landing phase. The lower extremities and the spine are most affected, with fractures being the most prevalent type of injury. More than half of the patients were admitted to hospital, with 10% requiring surgery, resulting in months of rehabilitation. Conclusion This study is the first in the Netherlands, and only the second worldwide to analyze technical incident databases in combination with data from medical information systems. Skydiving accidents of experienced jumpers should be considered as ‘high-energy trauma,’ therefore treatment should follow standard trauma guidelines. In less experienced skydivers, it is critical to conduct a secondary survey to assess the extremities adequately. Clinicians should also pay attention to friction burns that can arise due to friction between the skin and skydive equipment, a phenomenom that is already known in road traffic accidents.

BACKGROUND: Pre-hospital emergency medical services (PHEMS) training system is an integral part of the health system of any country. Therefore, knowing the status of graduates of this field can provide a new analysis for the policymakers of the National Health System. The purpose of this study was to analyze the status of PHEMS graduates in Iran. MATERIALS AND METHODS: The present survey research was conducted with the participation of 437 pre-hospital emergency medicine graduates of Iranian medical science universities in spring and summer of 2022. Sampling in this study was convenience. The documents of the National Organization of Educational Testing were used as well. The data collection tool was a researcher-made questionnaire. Statistical analyses were performed by SPSS25 software using descriptive statistics and analytical statistics. RESULTS: Among the graduates, the largest number (41.5%) was reported to be in the associate degree. According to the emergency system structure in Iran, graduates were employed in operational, communication, and headquarters areas, respectively, of which 76.8% were working in government centers. Most of the graduates were from the medical sciences universities of Zone 2 (35.6%) in the eastern area of Iran, while most of the workers were related to the medical sciences universities of Zone 1 (27.9%) in the capital region. CONCLUSION: Our findings revealed that the distribution of EMS graduates was not proportional to the distribution of the population and geographical area. Therefore, it is suggested that the policymakers of the country’s health system should make changes in the recruitment of students in each medical zone.

Background: Stroke is considered as one of the most important causes of emergency medical services (EMS) dispatch worldwide. Stroke is a time-sensitive condition and rapid transport of the patients improves the prognosis. In this study, we described prehospital emergency response times for stroke patients in Isfahan, Iran. Methods: In the current cross-sectional descriptive study, suspected stroke patients who were transported by EMS in Isfahan, Iran, from June 2022 to June 2023 were included. The data was extracted from patients’ files. The time interval between the receipt of a call and the EMS arrival at the scene (arrival time), the time interval between on-scene EMS arrival and the ambulance departure to the medical center (stroke scene time), and the time it takes to reach the medical center (transport time) were collected. Results: Overall, 79 patients with a mean age of 71.56 ± 12.03 were included. EMS diagnosed 63 (79.75%) of the patients with a definite diagnosis and 14 (17.72%) with probable stroke. Two false negative results were found. The average arrival time, was 11.56 ± 6.60 minutes, on-scene stroke time was 13.85 ± 7.23 minutes and the average transport time was 11.90 ± 6.08 minutes. The mean total EMS response time was 37.90 ±11.29 minutes. Conclusion: Overall, our study showed that while the EMS transport time is longer than ideal, the total time to transport to the hospital is short enough not to affect the outcome. EMS was also found to be adept at spotting the signs of stroke and rapidly starting the process of treatment.

ObjectiveFull compliance with American Heart Association (AHA) recommendations for prehospital care of stroke patients remains low. This study aims to identify components of prehospital care associated with shorter door-to-computed tomography (CT) times.MethodsData from a comprehensive stroke center's Get with the Guidelines-Stroke registry were supplemented by prehospital medical records for ischemic stroke patients between January 1, 2018, and December 31, 2020. Descriptive statistics and multivariable linear regression modeling was used to evaluate door-to-CT times for encounters compliant with AHA recommendations.ResultsThere were 621 ischemic stroke patients who presented via a prehospital provider, 452 of whom presented from the scene. Without adjusting for potential confounders, shorter door-to-CT times were observed with emergency medical services' documentation of a last-known well time, measurement of a blood glucose level, prenotification of a suspected stroke, or full compliance with AHA recommendations. Documentation of classic stroke signs, but not of a prehospital stroke scale, was also observed to have shorter door-to-CT times compared to encounters in which this did not occur.ConclusionDuring prehospital care of stroke, documentation of classic symptoms, obtaining a last-known well time or time of symptom onset, obtaining a blood glucose level, prenotifying the receiving hospital of suspected stroke, and complying fully with guidelines are associated with shorter door-to-CT times. Further studies are needed to understand if a shift in prehospital provider education, focusing on these key components of care, could lead to earlier diagnosis and treatment of acute stroke.

Background: Management of trauma patients includes prevention, prehospital care, appropriate resuscitation at a hospital, definitive treatment, and rehabilitation. Timely and adequate care for a trauma patient is paramount, which can dramatically impact survival. This study was planned to assess the proportion of patients who failed to receive adequate prehospital care before reaching our institute. Materials and Methods: A retrospective study was conducted in the trauma and emergency department of a level-1 trauma center in eastern India from February to April 2022. The demographic profile, vital parameters, injury, mode of transport, travel duration, referring hospital, and any interventions as per airway/breathing/circulation/hypothermia were collected. Results: The records of a hundred-two patients who were brought to the trauma and emergency department in the study period were reviewed. Road traffic accident involving two wheelers was the leading cause of injury. Eighty-three percent of the patients were referred from other health centers, of which 49 were referred from district headquarters hospitals. Only three patients out of 14 had been provided with an oropharyngeal airway for whom endotracheal intubation was indicated. Only one among the 41 patients needing Philadelphia collar actually received. Sixteen patients were provided supplemental oxygen out of the 35 for whom it was indicated. Out of 68 patients in whom intravenous cannulation and fluid administration were indicated, only 35 patients had received it. Out of 31 patients with fractures, none were provided immobilization. Conclusion: The care of the trauma patients with respect to airway, breathing, circulation, and fracture immobilization was found to be grossly inadequate, emphasizing the need of structured and protocol based prehospital trauma care.

Abstract Background Working in rural areas involves tackling long distances and occasional lack of supportive resources. Ambulance nurses are faced with the responsibility of making immediate autonomous decisions and providing extended care to critically ill patients during prolonged ambulance transport to reach emergency medical facilities. This study aims to expose the experiences of ambulance nurses acting as primary caregivers for critically ill patients during lengthy ambulance transfers in rural regions. Method Fifteen nurses employed in an ambulance service within sparsely populated rural areas were subjected to semi-structured interviews. The collected data underwent qualitative content analysis. Result The analysis resulted in one overarching theme with two categories. The theme is ‘Safety in the Professional Role,’ and the two categories are ‘Working in sparsely populated areas presents challenges’ and ‘Rare events: when routine cannot be established.’ The findings suggest that working as an ambulance nurse in a rural setting poses various challenges that can be highly stressful. Delivering care to critically ill patients during extended ambulance transports requires the knowledge, experience, and careful planning of the healthcare provider in charge. Conclusions The findings underscore the necessity for thorough planning and adaptable thinking when attending to critically ill patients during extended transport scenarios. The absence of supporting resources can render the task demanding. Nevertheless, participants reported an inherent tranquility that aids them in maintaining focus amid their responsibilities.

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

Hence, prehospital emergency medical personnel who work as frontliners should be trained.Patients and Methods: Data via pretest, posttest, and questionnaire surveys regarding the HART’s knowledge of and confidence in operational skills were collected using the 5-point Likert scale. The cohort included prehospital emergency medical personnel aged > 18 years. The training program comprised lectures, practicals, and examinations and included three subcourses: emergency medicine in the chemical, biological, radiation, and nuclear hazardous area (EM-CBRN) course; Thailand Tactical Emergency Medical Service (TTEMS) course; and cooperation and preparation for disaster (CPD) course.Results: The HART’s mean multiple choice question (MCQ) posttest knowledge score (12.80± 3.11) was significantly higher (p< 0.001) than the mean pretest knowledge score (7.74± 3.71) for the EM-CBRN course. The HART’s mean MCQ posttest knowledge score (24.04± 2.79) was significantly higher (p< 0.001) than the mean pretest knowledge score (14.34± 3.92) for the TTEMS course. Further, the HART’s mean MCQ posttest knowledge score (21.03± 3.49) was significantly higher (p< 0.001) than the mean pretest knowledge score (14.40± 5.08) for the CPD course. The HART’s mean confidence in operational skill score for the EM-CBRN course was significantly higher (p< 0.001) after training (4.45± 0.59) than before training (2.77± 0.90). The HART’s mean confidence in operational skill score for the TTEMS course was significantly higher (p< 0.001) after training (4.55± 0.59) than before training (2.78± 0.98). The HART’s mean confidence in operational skill score for the CPD course was significantly higher (p< 0.001) after training (4.70± 0.41) than before training (3.03± 0.90).Conclusion: The HART training program significantly affected the HART’s knowledge development and confidence in operational skills, particularly the frontline prehospital emergency medical personnel. Therefore, prehospital emergency medical personnel should undergo training, and learning activities must be developed to reinforce capacity and improve knowledge and confidence.Keywords: education, emergency medical service, hazardous substances, knowledge, prehospital emergency care

Abstract 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 Chi2 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. Trial registration This paper is part of the study “Rettungswageneinsatz ohne Transport” [“Ambulance deployment without transport”] (RoT), which was registered in the German Register of Clinical Studies under the number DRKS00017758.

Abstract Introduction The unpredictability of prehospital emergencies combined with constantly changing circumstances can lead to increased stress and mental health issues among Emergency Medical Technicians (EMTs). To accurately determine the stress-inducing factors in the prehospital environment, it is important to first identify the stressful events that occur in this environment. Therefore, this study strives to provide a thorough analysis of the stressors in the prehospital environment. Methods Sequential explanatory mixed methods were conducted in Hamadan prehospital emergency centers in 2022. The study included 251 EMTs, who were selected through a method in the quantitative phase. The quantitative part used a questionnaire consisting of basic information and the Posttraumatic Stress Questionnaire (PCL-5). In the qualitative phase, 17 with extensive experience in dealing with prehospital stressors were selected based on their PCL-5 scores (above 33). The qualitative phase analysis was carried out using the contractual content method using the Graneheim and Ladman's approach. Statistical analyzes for the quantitative and qualitative phases were performed using SPSS 21 and maxqda 10, respectively. Results The study revealed that the EMTs had an average PTSD score of 21. 60 ± 11. 45. Multivariate linear regression analysis showed that the number of shifts had a statistically significant relationship with PTSD scores (t = 26.38, P

Abstrac Background Treatment of acute pain is an essential element of pre-hospital care for injured and critically ill patients. Clinical studies indicate the need for improvement in the prehospital analgesia. Objective The aim of this study is to assess the current situation in out of hospital pain management in Germany regarding the substances, indications, dosage and the delegation of the use of analgesics to emergency medical service (EMS) staff. Material and methods A standardized survey of the medical directors of the emergency services (MDES) in Germany was carried out using an online questionnaire. The anonymous results were evaluated using the statistical software SPSS (Chi-squared test, Mann-Whitney-U test). Results Seventy-seven MDES responsible for 989 rescue stations and 397 EMS- physician bases in 15 federal states took part in this survey. Morphine (98.7%), Fentanyl (85.7%), Piritramide (61%), Sufentanil (18.2%) and Nalbuphine (14,3%) are provided as opioid analgesics. The non-opioid analgesics (NOA) including Ketamine/Esketamine (98,7%), Metamizole (88.3%), Paracetamol (66,2%), Ibuprofen (24,7%) and COX-2-inhibitors (7,8%) are most commonly available. The antispasmodic Butylscopolamine is available (81,8%) to most rescue stations. Fentanyl is the most commonly provided opioid analgesic for treatment of a traumatic pain (70.1%) and back pain (46.8%), Morphine for visceral colic-like (33.8%) and non-colic pain (53.2%). In cases of acute coronary syndrome is Morphine (85.7%) the leading analgesic substance. Among the non-opioid analgesics is Ketamine/Esketamine (90.9%) most frequently provided to treat traumatic pain, Metamizole for visceral colic-like (70.1%) and non-colic (68.6%) as well as back pain (41.6%). Butylscopolamine is the second most frequently provided medication after Metamizole for “visceral colic-like pain” (55.8%). EMS staff (with or without a request for presence of the EMS physician on site) are permitted to use the following: Morphine (16.9%), Piritramide (13.0%) and Nalbuphine (10.4%), and of NOAs for (Es)Ketamine (74.1%), Paracetamol (53.3%) and Metamizole (35.1%). The dosages of the most important and commonly provided analgesic substances permitted to independent treatment by the paramedics are often below the recommended range for adults (RDE). The majority of medical directors (78.4%) of the emergency services consider the independent application of analgesics by paramedics sensible. The reason for the relatively rare authorization of opioids for use by paramedics is mainly due to legal (in)certainty (53.2%). Conclusion Effective analgesics are available for EMS staff in Germany, the approach to improvement lies in the area of application. For this purpose, the adaptations of the legal framework as well as the creation of a guideline for prehospital analgesia are useful.

Patients were included from June 2018 to September 2019. Video recordings were made of patients being assessed with CPSS and PASS. The recordings were later presented to the healthcare professionals. To determine relative and absolute interrater reliability in terms of inter-rater agreement (IRA), we used generalisability theory. Group-level agreement was determined against a gold standard and presented as an area under the curve (AUC). The gold standard was a consensus agreement between two neurology consultants.Results: A total of 120 patient recordings were assessed by 30 EMS providers, two neurology residents and two neurology consultants. Using the CPSS and the PASS, a total of 1,800 assessments were completed by EMS providers, 240 by neurology residents and 240 by neurology consultants. The overall relative and absolute IRA for all items combined from the CPSS and PASS score was 0.84 (95% CI 0.80; 0.87) and 0.81 (95% CI 0.77; 0.85), respectively. Using the CPSS, the agreement on a group-level resulted in AUCs of 0.83 (95% CI 0.78; 0.88) for the EMS providers and 0.86 (95% CI 0.82; 0.90) for the neurology residents when compared with the gold standard. Using the PASS, the AUC was 0.82 (95% CI 0.77; 0.87) for the EMS providers and 0.88 (95% CI 0.84; 0.93) for the neurology residents.Conclusion: The high relative and absolute inter-rater agreement underpins a high robustness/generalisability of the two scales. A high agreement exists across individual raters and different groups of healthcare professionals supporting widespread applicability of the stroke scales.Plain Language Summary: Early stroke identification is pivotal to enable faster treatment. To aid this identification, many symptom-based stroke scales have been constructed for both stroke screening and severity assessment. In the prehospital environment, several scales have been evaluated on performance, but only few studies have evaluated the agreement between the ambulance personnel (emergency medical service (EMS) providers) and stroke physicians when interpreting the assessed symptoms in the scales. It is of great importance to know how EMS providers interpret symptoms seen in connection with the use of the scales to focus the continuous training of the EMS providers but also to aid the decision on which scale to implement in ambulances. From previous studies, we know that complex stroke scales are used to a considerably lesser extent than more simple scales, which could be caused by difficulties interpreting specific symptoms. In this study, a variety of methods was applied to determine the inter-rater agreement for two simple stroke scales using dichotomously evaluated symptoms. High inter-rater agreement between EMS providers and Stroke Neurologists exists both between individual raters and between raters grouped according to their profession and seniority. Previous studies have also found high inter-rater agreement for simple stroke scales but lesser agreement for more advanced scales. In conclusion, simple stroke scales seem to produce the highest agreement.Keywords: observer variation, prehospital emergency care, emergency medical service provider, neurologists, stroke

Recent research has yielded conflicting results on the use of spinal stabilization in prehospital care, with some guidelines expressing concerns about its potential lack of benefit or harm. Transportation on a backboard can cause pain, discomfort, and pressure ulcers, whereas the log-roll technique can cause unnecessary movement and aggravate existing injuries. The scoop stretcher and vacuum mattress provide comparable or better immobilization and comfort than the backboard. Prehospital time is critical, and patients with life-threatening conditions should undergo rapid stabilization procedures. Despite this, some studies have overlooked the scoop stretcher as a spinal stabilization device. The primary goal was to compare the time required to achieve spinal stabilization using a scoop stretcher versus a vacuum mattress. This was a monocentric, parallel, randomized (sealed envelope), superiority, open-label, controlled simulation experiment. All student paramedics, registered paramedics, and EMTs who work in the participating EMS were eligible to participate in the study apart of the study team. The experimental group had to use a scoop stretcher, whereas the control group used a vacuum mattress. Fifteen participants were included. The scoop stretcher group required less time to complete the stabilization procedure (median [Q1; Q3]: 127 seconds [111;145] versus 212 [156;237], p=0.005). Using a scoop stretcher for spinal stabilization is more time-efficient than a vacuum mattress, making it a viable option for unstable trauma patients in the prehospital setting. More research is needed to determine its efficacy in actual clinical practice.

BackgroundPrehospital emergency care is a critical but often understudied aspect of healthcare. Patient vulnerability in this setting can significantly impact outcomes. The aim of this study was to investigate the vulnerability status and to determine associated affect factors among prehospital emergency patients in China.MethodsIn this cross-sectional study conducted in China, from April 2023 to July 2023, we assessed the vulnerability of prehospital emergency patients using the Safety in Prehospital Emergency Care Index (SPECI) scale. We conducted a detailed questionnaire-based survey to gather demographic and disease-related information. We employed the SPECI scale, consisting of two subscales, to evaluate patient vulnerability. Statistical analyses, including t-tests, ANOVA, and multiple linear regression, were used to identify factors associated with vulnerability.ResultsThe study included a total of 973 prehospital emergency patients, with a response rate of 81.9%. These patients exhibited a low-to-moderate level of vulnerability, with an average SPECI score of 14.46 out of 40. Vulnerability was significantly associated with age (particularly those aged 60 and above), disease severity (severe conditions increased vulnerability), disease type (circulatory diseases correlated with higher vulnerability), alterations in consciousness, and chronic diseases. Unexpectedly, digestive system diseases were negatively correlated with vulnerability.ConclusionAddressing patient vulnerability in prehospital care is essential. Tailored interventions, EMS provider training, and interdisciplinary collaboration can mitigate vulnerability, especially in older patients and those with severe conditions.

AbstractObjective Severe trauma patients need immediate prehospital intervention and transfer to a specialised trauma hospital. In Norway, primary care doctors (PCDs) are an integrated part of the prehospital trauma care. The aim of this study was to investigate the degree to which PCDs were involved in prehospital care of severe trauma patients and how factors related to patients and doctors were associated with call-outs to these incidents.Design This was a registry-based study in Norway on severe trauma patients with acute hospital admission during the period 2012–2018.Setting Data was obtained from three Norwegian official registries.Subjects By linking the registries, we studied the actions taken by the PCDs, whether they called out to severe trauma incidents.Main outcome measures In multivariable regression models, we investigated whether factors related to the PCDs (age, sex, specialisation in general practice (GP)) and patients (age, sex, duration of hospital stay, type of injury) were associated with call-outs.Results Out of 4342 severe trauma incidents, PCDs had documented involvement in 1683 (39%) and called out to 644 (15%). Increased proportions of PCD call-outs to severe trauma incidents were significantly associated with lower age of PCD, being a GP specialist, lower patient age, being a male patient, increased length of hospital stay and injuries to the head and the neck.Conclusions PCDs called out to a relatively low proportion of severe trauma patients. Several factors related to patients and doctors were associated with call-outs to severe trauma incidents in Norway.

AbstractObjective To compare consultations with pregnant undocumented migrants at emergency primary health care to consultations with pregnant residents of Norway.Design A cross-sectional study of consultations at several time points.Setting The study was conducted at the Oslo Accident and Emergency Outpatient Clinic (OAEOC), the main emergency primary care service in Oslo, Norway.Subjects Consultations with pregnant patients without a Norwegian identity number seeking care at the Department of Emergency General Practice at the OAEOC were identified through a manual search of registration lists from 2009 to 2019. The consultations were categorized by women’s residency status as ‘probably documented migrant’, ‘uncertain migrant status’, or ‘probably undocumented migrant’. We also extracted aggregated data for women with a Norwegian identity number (i.e. residents) presenting in consultations with pregnancy-related (ICPC-2 chapter W) conditions.Main outcome measures Manchester Triage System urgency level at presentation, and hospitalization.Results Among 829 consultations with female patients categorized as probably undocumented migrants, we found 27.1% (225/829) with pregnant women. About half of the pregnant women (54.6% (123/225)) presented with a pregnancy-related condition. Pregnant women that were probably undocumented migrants had an increased risk of being triaged with a high level of urgency at presentation (relative risk (RR) 1.86, 95% CI 1.14–3.04) and being hospitalized (RR 1.68, 95% CI 1.21–2.34), compared to pregnant residents.Conclusion Pregnant undocumented migrants were more severely sick when presenting to emergency primary care services than pregnant residents. Increased access to primary care and emergency primary care services for pregnant undocumented migrants is urgently needed.

Background: Since a significant part of deaths due to traffic accidents are preventable in the pre-hospital phase, therefore it seems necessary to have an instrument to identify and measure the factors affecting it. This study aims to develop and psychometrically assess an instrument to measure preventable prehospital mortality due to traffic accidents. Methods: The study is a mixed qualitative-quantitative study, including systematic review, interviews, Delphi, and psychometrics. In the systematic review phase, using database searches, and in the qualitative phase, the factors affecting preventable mortality were extracted via interviews with 24 experts (fire-fighting organizations, traffic police, the Red Crescent, emergency medical services [EMS], emergency medicine, hospital emergency nurses and traffic accident victims) in Ministry of Health, Treatment and Medical Education and Yazd Province, Iran, 2020. The codes were classified with MAXQDA10 Software. The results were collected in the format of the primary instrument and the Delphi study (3 rounds) was conducted by experts. Finally, the reduction of the items and the psychometrics of the instrument, including the determination of face and content validity, and then the determination of the reliability using Cronbach’s alpha were performed. Results: The developed instrument had acceptable validity and reliability to be used in measuring preventable traffic-related pre-hospital mortalities. The final instrument to measure preventable pre-hospital mortality was developed with 5 dimensions, including “scene and casualty assessment, coordination and communication, time management, training performance, and support”. Conclusion: Using this instrument, preventable deaths can be detected, the present challenges can be identified, and the preventable deaths may be diminished.

Abstract Background Helicopter Emergency Medical Services (HEMS) are a limited and expensive resource, and should be intelligently tasked. HEMS dispatch was identified as a key research priority in 2011, with a call to identify a ‘general set of criteria with the highest discriminating potential’. However, there have been no published data analyses in the past decade that specifically address this priority, and this priority has been reaffirmed in 2023. The objective of this study was to define the dispatch criteria available at the time of the initial emergency call with the greatest HEMS utility using a large, regional, multi-organizational dataset in the UK. Methods This retrospective observational study utilized dispatch data from a regional emergency medical service (EMS) and three HEMS organisations in the East of England, 2016–2019. In a logistic regression model, Advanced Medical Priority Dispatch System (AMPDS) codes with ≥ 50 HEMS dispatches in the study period were compared with the remainder to identify codes with high-levels of HEMS patient contact and HEMS-level intervention/drug/diagnostic (HLIDD). The primary outcome was to identify AMPDS codes with a > 10% HEMS dispatch rate of all EMS taskings that would result in 10–20 high-utility HEMS dispatches per 24-h period in the East of England. Data were analysed in R, and are reported as number (percentage); significance was p 10% HEMS dispatch of all EMS taskings) resulted in 17 taskings per 24-h period. This definition derived nine AMPDS codes with high HEMS utility. Conclusion We have identified nine ‘golden’ AMPDS codes, available at the time of initial emergency call, that are associated with high-levels of whole-system and HEMS utility in the East of England. We propose that UK EMS should consider immediate HEMS dispatch to these codes.

Background and purpose: COVID-19 pandemic has affected different aspects of the health care system, including the outcomes of cardiac arrest. The purpose of this study was to compare out-of-hospital cardiac arrest (OHCA) during the first COVID-19 wave and the pre-COVID-19 time in Qom prehospital emergency care, Iran. Materials and methods: In a retrospective descriptive study, we compared the data of patients with OHCA who were registered in the Qom prehospital emergency care, during the first wave of COVID-19 (from 20 February to 3 April 2020) and the same period in 2018. The independent t-test was applied to analyze quantitative demographic data and Chi-square test was used to compare qualitative data and cardiopulmonary resuscitation (CPR) and its outcomes. Results: The incidence of OHCA was higher during COVID-19 pandemic than that in the same period in 2018 (248 cases vs. 189 cases). The incidence of cardiac arrest at home was also found to be significantly different between the two times (93.5% vs. 70.9%, P

Abstract Background As a result of several violent terrorist incidents, authorities in Sweden have shifted from previous approaches of being certain that it is safe for the ambulance service to enter the scene, to a one where “safe enough” is sufficient, potentially making it possible to save more lives. The aim was therefore to describe specialist ambulance nurses' perceptions of the new approach to assignments involving incidents with ongoing lethal violence. Methods This interview study employed a descriptive qualitative design with a phenomenographic approach in accordance with Dahlgren and Fallsberg. Results Five categories containing conceptual descriptions were developed from the analysis: Collaboration, Unsafe environments, Resources, Unequipped and Risk taking and self-protection. Conclusions The findings highlight the need to ensure that the ambulance service is a learning organisation, where clinicians with experience of an ongoing lethal violence event can pass on and share their knowledge with colleagues to prepare mentally for such an event. Potentially compromised security in the ambulance service when dispatched to ongoing lethal violence incidents needs to be addressed.

This issue is further compounded due to the multitude of contributing factors. Point of Care ultrasound (POCUS), especially when performed in prehospital care, that is before the patient is admitted to the ED has a high potential to reduce time of diagnosis and time of investigation which leads to shorter ED length of stay (LOS). The primary focus was on variances in ED LOS between the prehospital POCUS group and the standard care group.Patients and Methods: A cross-sectional study was conducted on prehospital patients who were admitted to the ED at Srinagarind Hospital, Thailand, from January to December 2021. We divided patients into two groups including patients who obtained prehospital POCUS (the prehospital POCUS group) and patients who received standard care treatment in which there was no prehospital POCUS performed (the standard care group). POCUS and ED medical records were documented and submitted for analysis.Results: Of 1348 prehospital patients, 840 were enrolled in this study: 169 with prehospital POCUS and 671 with standard care. Median LOS in the prehospital POCUS group was 159 min (IQR 89,289) versus 165 (IQR 102,330) in the standard care group (p = 0.125). Further imaging diagnostic test which affected ED LOS more than four hours was lower in the prehospital POCUS group (adjusted odds ratio [OR], 0.92; 95% confidence intervals [CI], 0.729– 1.666) than in the standard care group. The factor associated with increased odds of ED LOS more than four hour in the prehospital POCUS group was admission to hospital (adjusted OR 1.88; 95% CI, 1.230-2.239).Conclusion: Patients evaluated with prehospital POCUS had a shorter LOS than the only standard care treatment without statistical significance.Keywords: ultrasonography, prehospital emergency care, length of stay, emergency departments, crowding

Abstract A key focus is placed on engaging communities to become involved in making decisions to support health and care services in healthcare policies in England, UK. An example is the deployment of volunteers such as community first responders (CFRs), who are members of the public with basic life support skills, trained to intervene in emergency situations prior to the arrival of ambulance services. CFR policies have been devised by National Health Service (NHS) Trusts as a way of governing these and related activities. This paper critically examines the discourse around CFR policies to understand how CFR roles are organised and monitoring governance mechanisms are delineated in ensuring quality care delivery. We collected ten CFR policies from six ambulance services. Inductive analysis, guided by Foucault’s theory, enabled the identification of themes and subthemes. We found that Trusts have a common goal to make care quality assurances to regulatory bodies on CFR roles, and this is depicted in common hierarchies of individual responsibilities across Trusts. However, policies that govern approaches to CFRs activity vary. Firstly, the paper highlights institutional approaches to ensuring public safety through the application of organised surveillance systems to monitor CFR activities, and draws parallels between such surveillance and Foucault’s docile bodies. Secondly, the paper discusses how varying rules in the surveillance system compromises safety by decentralising knowledge to regulatory bodies to whom NHS Trusts must make safety assurances. We suggest that stronger interrelationships between Trusts in considering the CFR role has potential to increase public safety and outline a clearer direction for CFRs.

During emergencies, the time from symptom onset to definitive treatment determines the final outcome. Therefore, the emergency medical service (EMS) system in Korea, aims to transfer patients requiring emergency care to appropriate medical facilities within 30 minutes. This is in an attempt to improve the chances of survival and reduce sequelae. We attempted to locate areas vulnerable to prehospital transportation and identify hot spots with high demand for emergency medical helicopters in Jeju, by using a grid-based geospatial analysis. This retrospective cross-sectional observational study employed EMS data of 119 ambulance run sheets spanning from January 1, 2010 to September 30, 2018 in Jeju. The location data of emergency patients was superimposed on the spatial analysis frame using the geographic information system (GIS). Subsequently, the locations of long-distance transfer and delayed transfers to the hospital were analyzed, to identify hot spots where the demand for helicopter emergency services would be high. Of the total analysis targets, 42.2% (20,288 people) took more than 30 minutes from reporting to 119 dispatchers to hospital transfer. As the transfer time interval increased, the patient occurrence time increased in the city of Jeju, increased in Seogwipo, and the ratio of patients/ guardians to select a transfer hospital rose with significant differences. This study identified the characteristics related to time delays in prehospital transfer of emergency patients in Jeju, and the areas vulnerable to prehospital emergency care were derived and visualized through spatial analysis using the GIS.

Abstract Background Patients calling for an emergency ambulance and assessed as presenting with ‘unclear problem’ account for a considerable part of all emergency calls. Previous studies have demonstrated that these patients are at increased risk for unfavourable outcomes. A deeper insight into the underlying diagnoses and outcomes is essential to improve prehospital treatment. We aimed to investigate which of these diagnoses contributed most to the total burden of diseases in terms of numbers of deaths together with 1- and 30-day mortality. Methods A historic regional population-based observational cohort study from the years 2016 to 2018. Diagnoses were classified according to the World Health Organisation ICD-10 System (International Statistical Classification of Diseases and Related Health Problems, 10th edition). The ICD-10 chapters, R (‘symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified)’ and Z (‘factors influencing health status and contact with health services”) were combined and designated “non-specific diagnoses”. Poisson regression with robust variance estimation was used to estimate proportions of mortality in percentages with 95% confidence intervals, crude and adjusted for age, sex and comorbidities. Results Diagnoses were widespread among the ICD-10 chapters, and the most were ‘non-specific diagnoses’ (40.4%), ‘circulatory diseases’ (9.6%), ‘injuries and poisonings’ (9.4%) and ‘respiratory diseases’ (6.9%). The diagnoses contributing most to the total burden of deaths (n = 554) within 30 days were ‘circulatory diseases’ (n = 148, 26%) followed by ‘non-specific diagnoses’ (n = 88, 16%) ‘respiratory diseases’ (n = 85, 15%), ‘infections’ (n = 54, 10%) and ‘digestive disease’ (n = 39, 7%). Overall mortality was 2.3% (1-day) and 7.1% (30-days). The risk of mortality was highly associated with age. Conclusion This study found that almost half of the patients brought to the hospital after calling 112 with an ‘unclear problem’ were discharged with a ‘non-specific diagnosis’ which might seem trivial but should be explored more as these contributed the second-highest to the total number of deaths after 30 days only exceeded by ‘circulatory diseases’.

Abstract Background The work environment in prehospital emergency medical care setting is dynamic and complex and includes many stressors. However, little is known about the perceived human factors from the perspective of paramedics. In this study, we investigated, from the perspective of paramedics, what are the human factors, and how are they linked to prehospital emergency medical care? Methods Data were collected through semi-structured interviews (n = 15) with Finnish paramedics. The material was analyzed using inductive content analysis. Results Three main categories of human factors were identified. The first main category consisted of factors related to work which were divided into two generic categories: “Challenging organizational work environment” and “Changing external work environment.” The second main category comprised factors related to paramedics themselves and were divided into three generic categories: “Issues linked to personality,” “Personal experiences”, and “Factors resulting from personal features.” The third main category described that paramedics have difficulties in understanding and describing human factors. Conclusion This study revealed numerous factors that can affect paramedics’ work in the EMS setting. Increased knowledge about human factors in the EMS setting provides organizations with the opportunity to develop procedures that can support paramedics’ cognitive and physical work. Human factors in different situations can be addressed to improve occupational and patient safety.

Background Out-of-hospital cardiac arrest (OHCA) is a leading cause of preventable mortality that now affects almost 3,000 people each year in Ireland. Survival is low at 6–7%, compared to a European average of 8%. The Irish Out-of-Hospital Cardiac Registry (OHCAR) prospectively gathers data on all OHCA in Ireland where emergency medical services attempted resuscitation. The Irish health system has undergone several developments that are relevant to OHCA care in the period 2012–2020. OHCAR data provides a means of exploring temporal trends in OHCA incidence, care, and outcomes over time. It also provides a means of exploring whether system developments were associated with a change in key outcomes. This research aims to summarise key trends in available OHCAR data from the period 2012 – 2020, to explore and model predictors of bystander CPR, bystander defibrillation, and survival, and to explore the hypothesis that significant system level temporal developments were associated with improvements in these outcomes. Methods The following protocol sets out the relevant background and research approach for an observational study that will address the above aims. Key trends in available OHCAR data (2012 – 2020) will be described and evaluated using descriptive summaries and graphical displays. Multivariable logistic regression will be used to model predictors of ‘bystander CPR’, ‘bystander defibrillation’ and ‘survival to hospital discharge’ and to explore the effects (if any) of system level developments in 2015/2016 and the COVID-19 pandemic (2020) on these outcomes. Discussion The findings of this research will be used to understand temporal trends in the care processes and outcomes for OHCA in Ireland over the period 2012-2020. The results can further be used to optimise future health system developments for OHCA in both Ireland and internationally.

Although inadequate assessment and treatment of acute pain are associated with various complications, about 43% of adults suffering from pain are undertreated. This phenomenon is poorly studied, and limited data are available in the literature. The objective was to investigate the pain management in a prehospital emergency health-care setting, verifying pain assessment, pharmacological treatment adherence and the effectiveness of pain relief therapy.Patients and Methods: A retrospective observational study was conducted in a sample including all adults treated by the professionals of nurse-staffed ambulances and medical cars in an Italian Emergency Medical Services (EMS) from 1 January 2019 to 31 May 2019. We collected both demographic information and Numeric Rating Scale scores, which evaluated presence and intensity of pain, from the EMS paper forms. All analyses were performed using SPSS, version 27.Results: The study sample was composed of 629 people: 310 males (49%) and 319 females (51%), with an average age of 64.2± 22 years (range 18– 108). Pain information was collected in 75.5% (n = 475) of our sample; among them 222 patients (46.7%) suffered from pain. We recorded that 79.7% (n = 177) of the subjects with pain received no pharmacological treatment, and in almost all of the treated cases they did not adhere to the analgesia algorithm in use. Among those who were pharmacologically treated, pain statistically significantly decreased in intensity, from before to after, in both emergency vehicles (nurse-staffed ambulances pre m = 8.36± 0.9 vs post m = 4.18± 2.2, p< 0.001; medical cars pre m = 7.25± 1.7 vs post m = 3.50± 2.6, p< 0.001). Subsequently, pain was only re-ascertained in 24.3% of subjects.Conclusion: Our findings confirm that pain is a prevalent symptom in prehospital patients, especially in the younger age range, but that it remains an underrecognized, underestimated, and undertreated symptom with the risk of causing worse health outcomes.Keywords: pain assessment, pain management, prehospital emergency care, emergency medical services, undertreatment of pain

Abstract Introduction A prehospital system where obvious futile cases may be terminated prehospitally by physicians may reduce unethical treatment of dying patients. Withholding treatment in futile cases may seem ethically sound but may keep dying patients from becoming organ donors. The objective of this study was to characterise the prehospital patients who underwent organ donation. The aim was to alert prehospital physicians to a potential for an increase in the organ donor pool by considering continued treatment even in some prehospital patients with obvious fatal lesions or illness. Methods This is a retrospective register-based study from the Region of Southern Denmark. The prehospital medical records from patients who underwent organ donation after prehospital care from 1st of January 2016–31st of December 2020 were screened for inclusion. The outcome measures were prehospital diagnosis, vital parameters, and critical interventions. Results In the five year period, one-hundred-and-fifty-one patients were entered into a donation process in the health region following prehospital care. Sixteen patients were excluded due to limitations in data availability. Of the 135 patients included, 36.3% had a stroke. 36.7% of these patients were intubated prehospitally. 15.6% had subarachnoideal haemorrhage. 66.7% of these were intubated prehospitally. 10.4% suffered from head trauma. 64.3% of these patients were intubated at the scene. In 21.5% of the patients, the prehospitally assigned tentative diagnosis was missing or included a diverse spectrum of medical and surgical emergencies. Twenty-two patients (16.3%) were resuscitated from cardiac arrest. 81.8% were intubated at the scene. Conclusion The majority of the patients who became organ donors presented prehospitally with intracranial pathology. However, 30% of the patients that later underwent an organ donation process had other prehospital diagnoses. Among these, one patient in six had out-of-hospital cardiac arrest. Termination of treatment in patients with cardiac arrest is not uncommon in physician-manned prehospital emergency medical systems. An organ donation process cannot be initiated prehospitally but can be shut down if treatment is withheld or terminated. We contend that there is a potential for enlarging the donor pool if the decision processes in out-of-hospital cardiac arrest include considerations concerning future procurement of organ donors.

Introduction: According to excising findings, if the emergency management system (EMS) operation will be developed, the survival outcome of sepsis patients might improve. This study aimed to evaluate the pre-hospital associated factors of survival in sepsis patients. Methods: This retrospective cohort study was conducted on patients diagnosed with sepsis, coded with the Thailand emergency medical triage protocol and criteria-based dispatch symptom group 17. Information on the 30-day survival rate of patients was obtained from the electronic medical records. Pre-hospital factors associated with 30-day survival were analyzed using univariate and multivariate logistic regression analyses and were reported using odds ratio (OR) with 95% confidence interval (CI). Results: 300 patients diagnosed with sepsis were enrolled. Among them, 232 (77.3%) survived within 30 days. Non-survived cases had significantly older age (p = 0.019), lower oxygen saturations (92.5% vs. 95.0%; p = 0.003), higher heart rate (p = 0.001), higher respiratory rate (p < 0.001), lower level of consciousness (p < 0.001), higher disease severity based on qSOFA score (p = 0.001), and higher need for invasive airway management (p = 0.001) and supplementary oxygen (p = 0.001). The survival rate improved by 3.5% with every 1% increase in pre-hospital oxygen saturation (adjusted OR = 1.035, 95% CI: 1.005–1.066, p = 0.020) and the survival probabilities of patients who responded to voice (adjusted OR = 0.170, 95% CI: 0.050–0.579, p = 0.005), those who responded to pain (adjusted OR = 0.130, 95% CI: 0.036–0.475, p = 0.002), and those who were unresponsive (adjusted OR = 0.086, 95% CI: 0.026–0.278, p-value < 0.001) were lower than patients who were alert. Conclusion: The 30-day survival rate of patients with sepsis managed by the EMS team was 77.3%. Pre-hospital oxygen saturation and level of consciousness were associated with the survival of patients with sepsis who were managed in the pre-hospital setting.

Aim: To identify specific activities associated with high cognitive load during simulated pediatric out-of-hospital cardiac arrest (POHCA) resuscitation using physiological monitoring with functional near-infrared spectroscopy (fNIRS). Methods: We recruited teams of emergency medical services (EMS) responders from fire departments located throughout the Portland, OR metropolitan area to participate in POHCA simulations. Teams consisted of both paramedics and emergency medical technicians (EMTs), with one paramedic serving as the person in charge (PIC). The PIC was outfitted with the OctaMon to collect fNIRS signals from the prefrontal cortex. Signals reported changes in oxygenated and deoxygenated hemoglobin concentrations, which were used to determine moments of increased cognitive activity. Increased cognitive activity was determined by significant increases in oxygenated hemoglobin and decreases in deoxygenated hemoglobin. Significant changes in fNIRS signals were associated with specific concurrent clinical tasks recorded by two independent researchers using video review. Results: We recorded cognitive activity of EMS providers in 18 POHCA simulations. We found that a proportion of PIC’s experienced relatively high cognitive load during medication administration, defibrillation, and rhythm checks compared to other events. Conclusion: EMS providers commonly experienced increased cognitive activity during key resuscitation tasks that were related to safely coordinating team members around calculating and administering medications, defibrillation, and rhythm and pulse checks. Understanding more about activities that require high cognitive demand can inform future interventions that reduce cognitive load.

Objective: Pre-hospital emergency staff are involved in the front line of care for COVID-19 patients and face many challenges. The aim of this study was to explore the challenges of prehospital emergency staff in the COVID-19 pandemic. Methods: This qualitative research was conducted with a descriptive phenomenological approach. Purposeful sampling was applied and data collection was done through semi-structured interviews. Participants consisted of 16 pre-hospital emergency staff. Data analysis was performed using the Colaizzi approach. Results: Data analysis revealed five main themes including safety against COVID-19, knowledge deficit, fear and worry, challenges of transporting patients to the hospital, and selflessness. Conclusion: Pre-hospital emergency staff face many problems in personal, professional, equipment and cultural fields in the COVID-19 epidemic. In this regard, special attention from health systems is mandatory.

Abstract Introduction Prehospital advanced airway management, including endotracheal intubation (ETI), is one of the most commonly performed advanced life support skills. In South Africa, prehospital ETI is performed by non-physician prehospital providers. This practice has recently come under scrutiny due to lower first pass (FPS) and overall success rates, a high incidence of adverse events (AEs), and limited evidence regarding the impact of ETI on mortality. The aim of this study was to describe non-physician ETI in a South African national sample in terms of patient demographics, indications for intubation, means of intubation and success rates. A secondary aim was to determine what factors were predictive of first pass success. Methods This study was a retrospective chart review of prehospital ETIs performed by non-physician prehospital providers, between 01 January 2017 and 31 December 2017. Two national private Emergency Medical Services (EMS) and one provincial public EMS were sampled. Data were analysed descriptively and summarised. Logistic regression was performed to evaluate factors that affect the likelihood of FPS. Results A total of 926 cases were included. The majority of cases were adults (n = 781, 84.3%) and male (n = 553, 57.6%). The most common pathologies requiring emergency treatment were head injury, including traumatic brain injury (n = 328, 35.4%), followed by cardiac arrest (n = 204, 22.0%). The mean time on scene was 46 minutes (SD = 28.3). The most cited indication for intubation was decreased level of consciousness (n = 515, 55.6%), followed by cardiac arrest (n = 242, 26.9%) and ineffective ventilation (n = 96, 10.4%). Rapid sequence intubation (RSI, n = 344, 37.2%) was the most common approach. The FPS rate was 75.3%, with an overall success rate of 95.7%. Intubation failed in 33 (3.6%) patients. The need for ventilation was inversely associated with FPS (OR = 0.42, 95% CI: 0.20–0.88, p = 0.02); while deep sedation (OR = 0.56, 95% CI: 0.36–0.88, p = 0.13) and no drugs (OR = 0.47, 95% CI: 0.25–0.90, p = 0.02) compared to RSI was less likely to result in FPS. Increased scene time (OR = 0.99, 95% CI: 0.985–0.997, p

Background: Approximately 356,000 out-of-hospital cardiac arrests occur yearly (AHA, 2019), and prehospital providers must rely on their training to successfully resuscitate these patients. Despite advancements in their training, providers tend to hyperventilate patients, which has been linked to adverse health sequelae. While studies have briefly explored provider hand size as a variable, none have conclusively connected hand size and hyperventilation rates. Furthermore, minute ventilation (MV) has not been explored as a parameter of ventilation performance. Methods: A focused revisit of this relationship between hand size and ventilation performance through manikin simulation testing of 122 emergency medical services professionals in Maryland evaluated the ventilator parameters of breath rate (BR), tidal volume (TV), and MV. Results: The cohort's hyperventilation rate was 29%. In this study, evidence approaching statistical significance exists that participants with small hands (as determined by glove size) provide greater MV than other participants, yet no size-specific relationship was found for BR or TV. Further stratifying the participant certification level, the basic life support-certified providers with small hand sizes provided significantly greater BR administration. Conclusion: These findings affirm that hyperventilation is still a concern, MV is an important ventilator parameter to include in future studies, and a larger scale study is needed.

Police patrol officers (PPOs) face different types of encounters with acutely ill and injured people as first responders. The study aim was to explore and describe the emergency care competence needed for Swedish PPOs. The study had an exploratory design, and the data was collected using the Delphi technique from 43 experts in Sweden: police program educators (n=10), police authority instructors (n=11), and PPOs (n= 22). The results generated an understanding of emergency care competence that is relevant for PPOs. Basic assessment and basic life support measures for traumatic injuries and cardiac arrest (e.g., airway management, cardiopulmonary resuscitation (CPR), and hemorrhage control) received the highest levels of agreement among the experts, whereas more advanced assessments (taking care of people suffering from mental/medical illness or with drug/alcohol abuse) received lower levels of agreement. These results provide support for educators at the police programs and for the police authority in preparing PPOs to perform relevant out-of-hospital emergency care.

This study focused on developing a new model of emergency medical services (EMS) using a motorcycle-based ambulance (motorlance) with an automated external defibrillator (AED). There are currently no studies regarding access time for this vehicle. This study aimed at utilization of an AED in conjunction with motorlance and comparing the response time between a traditional ambulance and a motorlance.Methods: This was a prospective study conducted in the EMS department of Srinagarind Hospital, located in Khon Kaen, Thailand, over a five-month period, from September 2021 to January 2022. Data were recorded employing a national standard of operations record form used for Thailand EMS departments nationwide.Results: The 891 cases were divided into two groups which were motorlance and ambulance. The activation times for motorlance and ambulance were 0.44 minutes and 1.42 minutes, respectively (p < 0.001) and the response time in the motorlance group was 7.20 minutes compared with 9.25 minutes in the ambulance group. In OHCA, the motorlance with AED arrived at patients location and assisted to continue resuscitation at the hospital 88.9% of the time.Conclusion: AED used in conjunction with motorcycle ambulances had shorter periods of both activation time and response time compared to ambulances. The use of AEDs clearly increases the number of continuous resuscitations in out-of-hospital cardiac arrest patients.Keywords: ambulance, cardiac arrest, emergency care, prehospital emergency care, response time

Ambulance nurses in prehospital emergency care must assess, treat, and triage patients with mental health issues. This study aimed to investigate the self-perceived competence of ambulance nurses in prehospital emergency care of patients with mental illness. A cross-sectional questionnaire survey was done, a question-index value (Q-IV; range: 0–1.0) was defined as a summary of the proportion of positive responses (%). Correlations of self-perceived competence with education and professional experience were also examined. Overall self-perceived competence was good (mean Q-IV, 0.80). For six of the nine questions, women rated their abilities slightly lower than men. Women rated themselves as fairly good in providing “information about types of effective help available” (Q-IV, 0.55) and in “suggesting tactics for helping a person with mental illness feel better” (Q-IV, 0.56). Men rated their competence as fairly good in “directing patients to appropriate sources of help” (Q-IV, 0.58). Self-perceived competence did not correlate with education level or professional experience. In conclusion, these results indicate that in encounters with patients who have mental illness, ambulance nurses perceive their overall competencies as good, with some sex-based differences in self-perception for specific knowledge areas. Education level and professional experience did not correlate with self-perceived competence.

Background Out-of-hospital cardiac arrest (OHCA) is a leading cause of preventable mortality that now affects almost 3,000 people each year in Ireland. Survival is low at 6-7%, compared to a European average of 8%. The Irish Out-of-Hospital Cardiac Registry (OHCAR) prospectively gathers data on all OHCA in Ireland where emergency medical services attempted resuscitation. The Irish health system has undergone several developments that are relevant to OHCA care in the period 2012-2020. OHCAR data provides a means of exploring temporal trends in OHCA incidence, care, and outcomes over time. It also provides a means of exploring whether system developments were associated with a change in key outcomes. This research aims to summarise key trends in available OHCAR data from the period 2012 – 2020, to explore and model predictors of bystander CPR, bystander defibrillation, and survival, and to explore the hypothesis that significant system level temporal developments were associated with improvements in these outcomes. Methods The following protocol sets out the relevant background and research approach for an observational study that will address the above aims. Key trends in available OHCAR data (2012 – 2020) will be described and evaluated using descriptive summaries and graphical displays. Multivariable logistic regression will be used to model predictors of ‘bystander CPR’, ‘bystander defibrillation’ and ‘survival to hospital discharge’ and to explore the effects (if any) of system level developments in 2015/2016 and the COVID-19 pandemic (2020) on these outcomes. Discussion The findings of this research will be used to understand temporal trends in the care processes and outcomes for OHCA in Ireland over the period 2012-2020. The results can further be used to optimise future health system developments for Out-of-Hospital Cardiac Arrest in both Ireland and internationally.

Objective: To compare the characteristics of the emergency medical services (EMS) brought COVID-19 patients versus self-referred walk-in patients. Methods: This was a Cross-sectional study of COVID-19 infected cases in Jahrom, south of Iran. Age, sex, the symptoms of beginning days’ passing, respiratory distress, PO2 at arrival, admission length and inhospital death were retrieved for confirming COVID-19 cases in the whole 2020 year. Respiratory distress was considered as the sign that agitates the patient to call EMS care. Survival analysis was used to evaluate the possible difference of the hospitalization outcome in EMS brought or Self-referred walk-in (SRW) patients. Results: There was 704 (27.1%) registries patients transfer to the hospital by EMS and 1895 (72.9%) cases with SRW referred to the hospital. The survival distributions for the EMS group were statistically significant and lower than SRW group (p

ContextThe prehospital emergency system is essential for reducing mortality and disability in emergency patients. However, the high turnover rate of prehospital emergency physicians (PEPs) remains the most prominent problems in the prehospital emergency system. Turnover intent (TI) is predictive of actual turnover behavior; however, previous studies have mainly focused on sociodemographic factors and job characteristics, ignoring many other potential psychological factors, such as professional identity (PI) and job burnout (JB).ObjectivesTo measure the level of PI, JB, and TI of PEPs in Beijing, China. We analyze the distribution of TI in different social demography PEPs and then further explore the influence of PI and JB on TI, to provide a reference and suggestions for government departments to reduce the TI of PEPs.MethodsAn online questionnaire was distributed to 552 PEPs in Beijing, and a total of 533 valid questionnaires were included. T-test and variance analysis were used to examine the differences in the distribution of TI among different sociodemographic PEPs. Pearson's correlation analysis was used to test the correlation between PI, JB, and TI. The SEM was used to analyze the relationships among PI, JB, and TI.ResultsUnivariate analysis showed that age, marital status, education, professional title, work experience, department and hukou were significantly associated with TI. Pearson's correlation analysis showed that PI was negatively associated with JB and TI, and JB was positively associated with TI. Professional treatment identity (PTI, β = −0.24, 95% CI: −0.38~-0.11), professional meaning identity (PMI, β = −0.12, 95% CI: −0.23~0.03), and emotional exhaustion (EE, β = 0.40, 95% CI: 0.28~0.51) seem to have direct impacts on TI. Given the mediating role played by EE, PTI may have an indirect negative effect on TI (β = −0.24, 95% CI: −0.32~0.16).ConclusionPI and JB of PEPs in China are closely related to TI, which may have unexpected effects on government departments to stabilize the team of PEPs through a series of control measures. According to the above results, the professional treatment of PEPs needs to be improved, and external learning opportunities should be increased. Legalization of medical rescue workers should also be on the agenda.

Introduction: Pain has been identified as the most common reason for emergency medical service (EMS) calls. Despite many years of pain research, it is still true that oligoanalgesia is an ongoing phenomenon. This demonstrates the need for the implementation of new solutions and for further analyses on the causes of inadequate pain treatment. The study was undertaken to analyze analgesic treatment implemented in specialist “S” and basic “P” Emergency Medical Teams (EMTs). Methods: This retrospective study was based on the analysis of medical records using the emergency medical service card. A total of 1333 medical files were analyzed, of which 539 cases were qualified for the study according to the inclusion and exclusion criteria. Results: The analysis has shown that the majority of interventions were undertaken by basic emergency medical teams and that acute pain was the most common reason for contacting the EMS. However, only 62.52% of patients received analgesia. It was shown that the frequency of administering paracetamol, metamizole, and ketoprofen was proportional to the increase in pain intensity. Similar correlations were identified in the cases of morphine, fentanyl, and drotaverine, which were most often administered to patients with the most severe pain. Conclusions: The nature and location of pain, as well as its intensity, affected the choice of analgesia. Opioids were administered more frequently with more extensive injuries and at greater pain intensity. Significant differences were found in the frequency at which acetylsalicylic acid was administered more often in “S” EMTs and drotaverine more often in “P” EMTs. The intravenous route was found to be the most common route of analgesia administration in EMTs.

Background and Objectives: Despite advancements in modern medicine, the survival rate of patients after out-of-hospital cardiac arrest (OHCA) remains low. The proportion of OHCA patients who could be saved under ideal circumstances is unknown. A significant portion of patients experience cardiac arrest due to irreversible conditions. The survival of patients with reversible causes depends on the prompt initiation of basic life support (BLS) and early defibrillation. In order to increase the chances of survival, the motorcycle paramedic (MP) project was implemented in Ljubljana in 2003. The MP is equipped with an AED. In the case of OHCA with a shockable rhythm, he performs defibrillation before the arrival of the emergency medical team (EMT). The aim of this study was to evaluate whether the MP, by reducing response times to OHCA patients, increases the survival and outcome of these patients compared to the EMT. Materials and Methods: A retrospective analysis of OHCA cases within the area covered by Ljubljana Emergency Medical Service (EMS) was conducted for the period from January 2003 to December 2022. Instances where the MP arrived at the scene before the EMT were considered MP interventions and classified as the MP group; all other interventions were classified as the EMT group. Results: Between January 2003 and December 2022, the EMT performed resuscitation on 3352 patients. In 316 cases, the MP was simultaneously activated and arrived at the scene before the EMT. The response time in the MP group was shorter compared to the EMT group (7.7 ± 4.1 min vs. 9.9 ± 6.5 min, p < 0.001). In 16 patients, return of spontaneous circulation (ROSC) was achieved before the arrival of the EMT. The MP group had a higher ROSC rate, a larger proportion of patients were discharged from the hospital and there were more patients with a good neurological outcome compared to the EMT group (44.3% vs. 36.9%, p = 0.009; 18.7% vs. 13.0%, p = 0.005; 15.9% vs. 10.6%, p = 0.004, respectively). Conclusion: This study has demonstrated that the implementation of the MP into the EMS in Ljubljana has resulted in shorter response times, an increased survival rate and improved neurological outcome for OHCA patients.
