Prehospital care and interfacility transfer of trauma patients before reaching the emergency of a level-1 trauma care center.

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.

Comprehensive analysis of vulnerability status and associated affect factors among prehospital emergency patients: a single-center descriptive cross-sectional study.

Background: Prehospital 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. Methods: In 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. Results: The 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. Conclusion: Addressing 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.

The ground is the limit: epidemiology of skydiving accidents over 25 years and in 2.1 million jumps in the Netherlands with sub-analysis of injuries reported by medical professionals in the past five years.

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.

Smartphone AI vs. Medical Experts: A Comparative Study in Prehospital STEMI Diagnosis.

PURPOSE: Prehospital telecardiology facilitates early ST-elevation myocardial infarction (STEMI) detection, yet its widespread implementation remains challenging. Extracting digital STEMI biomarkers from printed electrocardiograms (ECGs) using phone cameras could offer an affordable and scalable solution. This study assessed the feasibility of this approach with real-world prehospital ECGs. MATERIALS AND METHODS: Patients suspected of having STEMI by emergency medical technicians (EMTs) were identified from a policy research dataset. A deep learning-based ECG analyzer (QCG™ analyzer) extracted a STEMI biomarker (qSTEMI) from prehospital ECGs. The biomarker was compared to a group of human experts, including five emergency medical service directors (board-certified emergency physicians) and three interventional cardiologists based on their consensus score (number of participants answering "yes" for STEMI). Non-inferiority of the biomarker was tested using a 0.100 margin of difference in sensitivity and specificity. RESULTS: Among 53 analyzed patients (24 STEMI, 45.3%), the area under the receiver operating characteristic curve of qSTEMI and consensus score were 0.815 (0.691-0.938) and 0.736 (0.594-0.879), respectively (p=0.081). Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of qSTEMI were 0.750 (0.583-0.917), 0.862 (0.690-0.966), 0.826 (0.679-0.955), and 0.813 (0.714-0.929), respectively. For the consensus score, sensitivity, specificity, PPV, and NPV were 0.708 (0.500-0.875), 0.793 (0.655-0.966), 0.750 (0.600-0.941), and 0.760 (0.655-0.880), respectively. The 95% confidence interval of sensitivity and specificity differences between qSTEMI and consensus score were 0.042 (-0.099-0.182) and 0.103 (-0.043-0.250), respectively, confirming qSTEMI's non-inferiority. CONCLUSION: The digital STEMI biomarker, derived from printed prehospital ECGs, demonstrated non-inferiority to expert consensus, indicating a promising approach for enhancing prehospital telecardiology.

Factors associated with prolonged on-scene time in ambulance transportation among patients with minor diseases or injuries in Japan: a population-based observational study.

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.

Ambulance nurses' experiences as the sole caregiver with critical patients during long ambulance transports: an interview study.

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.

Redesigning Prehospital Care: Fiji's Response to the COVID-19 Pandemic.

The benefits of emergency care systems in low- and middle-income countries are well-described. Passed in the wake of the coronavirus disease 2019 (COVID-19) pandemic, the World Health Assembly (WHA) Resolution 76.2 emphasizes the importance of communication, transportation and referral mechanisms, and the linkages between communities, primary care, and hospital care. Literature describing prehospital care and ambulance system development is scarce, with little data on the effectiveness and cost effectiveness of different options. Prehospital care systems in Pacific Island countries are under-developed. In Fiji, out-of-hospital care is fragmented with an uncoordinated patchwork of ambulance providers. There is no scope of practice or training requirement for providers and no patient care records. There are no data relating to demand, access, and utilization of ambulance services.In response to a surge of COVID-19 cases in 2021, the Fiji government created a Prehospital Emergency Care Coordination Center (PHECCC) in the capital Suva, which was operational from July-October 2021. Access was via a toll-free number, whereby the public could receive a medical consultation followed by phone advice or dispatch of an ambulance for a home assessment, followed by transportation to hospital, if required. The PHECCC also provided coordination of inter-facility transport and retrieval of the critically ill.The system that was created met many of the prehospital care standards set by emergency care leaders in the region and created the first dataset relating to ambulance demand and utilization. This is the first article to document prehospital system development in the Pacific region.

Factors influencing witnesses' perception of patient safety during pre-hospital health care from emergency medical services: A multi-center cross-sectional study.

AIM: To determine the factors related with the perception of feeling safe during pre-hospital emergency care. METHODS: A multi-centred, cross-sectional study. Data collection from April 2021 to March 2022, in the Centro de Emergencias Sanitarias 061 (Andalusia, Spain). INCLUSION CRITERIA: witnesses of health care by emergency medical services. EXCLUSION CRITERIA: minors, or communication barriers. OUTCOME VARIABLE: Witness Perceived Safety Scale ESPT10. The variables studied were related with sociodemographic data, the request for health care, the patient, the hospital transfer and patient safety incidents. A multivariate linear regression model was constructed for the dependent variable. The study followed STROBE statement. RESULTS: Responses were obtained from 1400 witnesses. The linear regression model showed that the score on the scale increased as the witnesses felt more satisfied (B = 1.302; p < 0.001). On the contrary, the score was lower when the witness reported a patient safety incident (B = -2.856; p < 0.001 and B = -3.166; p < 0.001), or when the assistance took place in a public space (B = -0.722; p = 0.017). CONCLUSIONS: The level of satisfaction, the occurrence of a patient safety incident, and the place of health care are related factors with the perception of the witnesses. The Witness Perceived Safety Scale ESPT10 could be considered a valid and useful patient safety indicator.

Effect of urgency level on prehospital emergency transport times: a natural experiment.

Accurate estimation of ambulance transport time from the scene of incident to arrival at the emergency department (ED) is important for effective resource management and emergency care system planning. Further, differences in transport times between different urgency levels highlight the benefits of ambulance transports with highest urgency level in a setting where ambulances are allowed to not follow standard traffic rules. The objective of the study is to compare ambulance urgency level on the differences in estimates of ambulance transport times generated by Google Maps and the observed transport times in a prehospital setting where emergency vehicles have their own traffic laws. The study was designed as a natural experiment and register study. Ambulance transports dispatched with different levels of urgency (Level A and B) were included in the Central Denmark Region (a mixed urban and rural area) from March 10 to June 11, 2021. Ambulance transports for highest urgency level were compared to lowest urgency level with Google Maps estimated transport times as reference. We analyzed 1981 highest urgency level and 8.958 lowest urgency level ambulance transports. Google Maps significantly overestimated the duration of transports operating at highest level of urgency (Level A) by 1.9 min/10 km (95% CI 1.8; 2.0) in average and 4.8 min/10 km (95% CI 3.9; 5.6) for the first driven 10 km. Contrary, Google Maps significantly underestimated the duration of transports operating at lowest level of urgency (Level B) by -1.8 min/10 km (95% CI -2.1; -1.5) in average and -4.4 min/10 km (95% CI -5.4; -3.5) for the first driven 10 km. Google Maps systematically overestimates transport times of ambulance transports driven with Level A, the highest level of urgency in a setting where ambulances are allowed to not follow standard traffic rules. The results highlight the benefit of using urgency Level A and provide valuable information for emergency care management.

Ambulance deployment without transport: a retrospective difference analysis for the description of emergency interventions without patient transport in Bavaria.

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.

Effects of the Hazardous Area Response Team Training Program on the Knowledge and Confidence in Operational Skills of Prehospital Emergency Medical Personnel in Thailand: A Quasi-Experimental Study.

Background: Hazardous areas are places emitting hazardous materials, terrorist- or war-related, which lead to public health risks in developed and developing countries globally. 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.

Critical hypertension in trauma patients following prehospital emergency anaesthesia: a multi-centre retrospective observational study.

BACKGROUND: Critical hypertension in major trauma patients is associated with increased mortality. Prehospital emergency anaesthesia (PHEA) is performed for 10% of the most seriously injured patients. Optimising oxygenation, ventilation, and cerebral perfusion, whilst avoiding extreme haemodynamic fluctuations are the cornerstones of reducing secondary brain injury. The aim of this study was to report the differential determinants of post-PHEA critical hypertension in a large regional dataset of trauma patients across three Helicopter Emergency Medical Service (HEMS) organisations. METHODS: A multi-centre retrospective observational study of consecutive adult trauma patients undergoing PHEA across three HEMS in the United Kingdom; 2015-2022. Critical hypertension was defined as a new systolic blood pressure (SBP) > 180mmHg within 10 min of induction of anaesthesia, or > 10% increase if the baseline SBP was > 180mmHg prior to induction. Purposeful logistical regression was used to explore variables associated with post-PHEA critical hypertension in a multivariable model. Data are reported as number (percentage), and odds ratio (OR) with 95% confidence interval (95%CI). RESULTS: 30,744 patients were attended by HEMS during the study period; 2161 received PHEA and 1355 patients were included in the final analysis. 161 (11.9%) patients had one or more new episode(s) of critical hypertension ≤ 10 min post-PHEA. Increasing age (compared with 16-34 years): 35-54 years (OR 1.76, 95%CI 1.03-3.06); 55-74 years (OR 2.00, 95%CI 1.19-3.44); ≥75 years (OR 2.38, 95%CI 1.31-4.35), pre-PHEA Glasgow Coma Scale (GCS) motor score four (OR 2.17, 95%CI 1.19-4.01) and five (OR 2.82, 95%CI 1.60-7.09), patients with a pre-PHEA SBP > 140mmHg (OR 6.72, 95%CI 4.38-10.54), and more than one intubation attempt (OR 1.75, 95%CI 1.01-2.96) were associated with post-PHEA critical hypertension. CONCLUSION: Delivery of PHEA to seriously injured trauma patients risks haemodynamic fluctuation. In adult trauma patients undergoing PHEA, 11.9% of patients experienced post-PHEA critical hypertension. Increasing age, pre-PHEA GCS motor score four and five, patients with a pre-PHEA SBP > 140mmHg, and more than intubation attempt were independently associated with post-PHEA critical hypertension.

Entrusting life to professionals: A phenomenological hermeneutical study of older persons' participation in prehospital emergency care involving municipal home care and ambulance services.

BACKGROUND: Participation in care is considered to promote safe and qualitative care. Care-dependent older persons ageing in place have increased emergency care needs, which initiate inter-organisational collaboration involving municipal home care and ambulance services. Previous research concludes that uncertainties exist regarding what participation in care means in clinical practice, which necessitates the need to illuminate the phenomenon for older persons in critical life situations. AIM: This study aimed to illuminate meanings of participation in prehospital emergency care from the perspective of care-dependent older persons experiencing acute illness at home. DESIGN: This study has a qualitative design with a lifeworld approach. METHOD: A phenomenological hermeneutical method was used to analyse transcribed telephone interviews with eleven care-dependent persons aged 70-93 years. RESULTS: Care-dependent older persons' participation in prehospital emergency care means 'Entrusting life to professional caregivers' when being in helpless solitude and existentially unsafe, which emphasises a deepened interpersonal dependence. Meanings of participation in care from the perspective of older persons involve Being reassured in togetherness, Being pliant in trust of emergency expertise, Being enabled through the agency of professional caregivers, and Encountering readiness in the emergency care chain. CONCLUSION: Care-dependent older persons' participation in prehospital emergency care is existential and involves interpersonal dependence. Togetherness brings reassurance, safety and opportunity for emotional rest while accessing the professional caregivers' power, competence and abilities which provide opportunities for existence and movement towards well-being and continued living. IMPLICATIONS FOR PRACTICE: Prehospital emergency care from the perspective of care-dependent older persons transcends organisational boundaries and includes the municipal mobile safety alarm service. The involved municipal and regional organisations need to provide support by implementing lifeworld-led care models and care alternatives that enable professionals to recognise the existential dimension of participation in care.

Navigating into the unknown: exploring the experience of exposure to prehospital emergency stressors: a sequential explanatory mixed-methods.

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 < 0.001). The qualitative phase of the study included 17 interviews, resulting in 14 subcategories, which consisted of four categories: "the overall impact of the stress crisis on technicians," "missing links in the communication network in incident management," "professional shortcomings in pre-hospital care," and "the complex and multifaceted context of stressful pre-hospital emergencies." Additionally, the study's theme was centered around "surveying the experiences of EMTs in stressful environments." CONCLUSION: As the number of shifts increased, the primary cause of the high prevalence of PTSD in EMTs was revealed. Prehospital emergency stress can be reduced and managed more skillfully by adjusting various factors such as shortening workdays, offering continuous training, augmenting workforce, supplying ambulance equipment insurance, refraining from hiring personnel devoid of clinical training, hiring psychologists, hiring midwives in an emergency, updating prehospital protocols and guidelines, encouraging cooperation between EMTs and other relief groups, and utilizing cutting-edge technologies.

Time to Reconsider Analgesia in Mass Casualty Incidents.

The provision of analgesia in mass casualty incidents has traditionally been viewed as low-priority and reserved for later stages of care. Poor pain management is commonplace in trauma victims, and inadequate acute pain management can hinder evacuation efforts and may lead to the development of chronic pain and posttraumatic stress disorder. New, safe, and simple methods for administering quality analgesia have proven to be safe and effective in the prehospital setting and, as such, could easily be implemented into mass casualty incident protocols and allow for analgesia at earlier stages in such incidents, thereby improving patient care.

A Motorcycle Paramedic Increases the Survival Rate of Patients after OHCA.

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.

Prehospital Clinical Decision-Making for Medication Administration for Behavioral Emergencies.

Introduction: Prehospital behavioral emergency protocols provide guidance on when a medication may be necessary for prehospital behavioral emergency. However, the final decision of which medication to administer to a patient is made independently by paramedics. The authors evaluated circumstances in a prehospital behavioral emergency when paramedics considered chemical restraints, and factors that go into choosing which medications to administer. Methods: A qualitative research design was used involving paramedics from a Midwestern County in the United States, between November 18 and 26, 2019. A total of 149 paramedics were asked to complete a survey consisting of two open-ended questions to measure their clinical decision-making process and factors considered when selecting a medication from a behavioral emergencies protocol. An immersion-crystallization approach was used to analyze the content of the interviews. Results: There was a 53% (n = 79) response rate. Six major themes emerged regarding the paramedics' decisions to use medication for behavioral emergencies: safety of the patients and paramedics, inability to use calming techniques, severity of the behavioral emergency, inability to assess the patient due to presentation, etiology of the behavioral episode, and other factors, such as age, size, and weight of the patient. Six major themes emerged regarding factors considered when choosing medication for behavioral emergency: etiology of the behavioral emergency, patient presentation, the patients' history and age, desired effect and intended outcome of the medication, and other factors. Conclusions: Emergency medical services (EMS) paramedics relied on several factors, such as safety of all parties involved and etiology of the behavioral emergency in deciding when, and which medication to use in a behavioral emergency. The findings could help EMS administrators to develop protocols, such as how paramedics respond and treat patients with behavioral health emergencies.

Application of analgesics in emergency services in Germany: a survey of the medical directors.

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.

Outcomes of out-of-hospital cardiac arrest in Ireland 2012-2020: Protocol for an observational study.

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.

Inter-Rater Agreement on Cincinnati Prehospital Stroke Scale (CPSS) and Prehospital Acute Stroke Severity Scale (PASS) Between EMS Providers, Neurology Residents and Neurology Consultants.

Objective: To examine the agreement between emergency medical service (EMS) providers, neurology residents and neurology consultants, using the Cincinnati Prehospital Stroke Scale (CPSS) and the Prehospital Acute Stroke Severity Scale (PASS). Methods: Patients with stroke, transient ischemic attack (TIA) and stroke mimic were included upon primary stroke admission or during rehabilitation. 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.
