Background: Acute heart failure (AHF) is a common reason for emergency care, yet data on its epidemiology and prognosis in the prehospital setting remain limited. This study aims to analyze the characteristics and long-term survival outcomes of patients with AHF managed by emergency medical services (EMSs). Methods: A multicenter, prospective, observational study was conducted in adult patients attended by EMSs and transferred to emergency departments (EDs). Collected data included demographics, vital signs, laboratory parameters, chronic obstructive pulmonary disease (COPD) history, comorbidity burden assessed using the Age-adjusted Charlson Comorbidity Index (aCCI), and clinical outcomes. The primary endpoint was 2-year mortality (M2Y). Survival analysis was performed using Cox regression and Kaplan–Meier analysis. Results: A total of 417 patients were included. Their median age was 84 years, and 48.2% were women. A total of 92.3% of the patients had an elevated aCCI. Overall, M2Y was 57.6%, rising to 74.4% among COPD patients. aCCI range and elevated plasma potassium and lactate levels were independently associated with reduced survival (HR 2.86, 1.45 and 1.15, respectively). Overall, 50% of all deaths occurred within the first 49 days. Conclusions: AHF patients attended by EMSs exhibited high 2-year mortality, likely due to advanced age and comorbidities. High comorbidity burden and abnormal potassium and lactate levels were linked to worse outcomes. Full article

Background: Older adults (≥65 years) account for a substantial share of Emergency Medical Service (EMS) activations, yet differences between nursing homes (NHs) and the community are insufficiently defined. This study aimed to compare EMS responses for older adults inside and outside NHs. Methods: We conducted a retrospective observational study of all EMS activations involving patients ≥65 years in a rural German region from July 2020 to March 2025, based on fully anonymized prehospital patient care reports electronically documented on tablets. Prehospital patient care was assessed using the ABCDE approach, with additional analysis of feedback codes transmitted to the control center (response and on-scene times, physician dispatch, lights and sirens use, feedback codes, hospital destination, and admission urgency). Continuous variables were summarized as mean (SD) or median [IQR], categorical variables as n (%), and group comparisons performed using the Chi-Square test or Fisher’s exact test (categorical) and the t test or Mann–Whitney U test (continuous), as appropriate. Results: Among 46,598 EMS activations in adults aged ≥65 years, 28,749 EMS responses were included in the analysis after excluding non-emergency transports and duplicate physician records. Of these, 20% occurred in NHs (5707/28,749) and 80% in the community (23,042/28,749). Median age was 85 years (IQR 80–89) in NH patients and 80 years (IQR 73–86) in community patients (p < 0.001). Females accounted for 60% (3450/5705) of NH patients and 53% (12,223/23,036) of community patients (p < 0.001). Emergency physicians were dispatched in 7% of NH incidents (392/5707) and 10% of community incidents (2327/23,042; p < 0.001). In NHs, bronchitis/pneumonia was a leading feedback code (6%, 354/5707), whereas in community patients, acute coronary syndrome (ACS) was prominent (5%, 1249/23,042). Admission urgency categories also differed significantly, with NH residents classified as category 3 (outpatient evaluation) in 11% (621/5706) and category 0 (no admission) in 5% (280/5706), whereas community patients were more often classified as category 1 (immediate intervention) in 13% (2886/23,037) (all p < 0.001). Conclusions: NH residents were older, more often female, and presented with low-to-moderate acuity. Frequent diagnoses were closed extremity injuries and bronchitis/pneumonia. In contrast, ACS and other cardiovascular emergencies were more common in the community, particularly among men, consistent with international evidence on sex-specific incidence. NH residents were more often classified as non-urgent or outpatient and transported to nearby hospitals, whereas community patients more frequently required immediate intervention and referral to tertiary centers. In summary, EMS responses for older adults differed in clinical presentations, operational patterns, and hospital pathways. Full article

Background/Objectives: Patients with multimorbidity frequently rely on emergency services when continuity of care is weak. Strengthening communication between emergency and primary care can prevent unnecessary hospitalizations, yet this relationship remains underexplored. The aim of this study was to analyze the relationship between primary health care utilization in patients with multimorbidity and their demand for prehospital emergency services. Methods: An observational, longitudinal, analytical, and retrospective study was conducted in Málaga (Spain) between 2013 and 2017. Adults (>18 years) with multimorbidity who requested prehospital emergency care services at home were included; those with cancer, rare diseases, severe mental disorders, or incomplete electronic records were excluded. Variables encompassed sociodemographic, clinical, and behavioral characteristics, comorbidities, functional status, polypharmacy, resource type, and outcomes (on-site resolution or hospital referral). Primary health care visits before and after prehospital emergency use were extracted from electronic records. Descriptive, bivariate, and multivariate analyses were performed. Results: Among 532 patients, prior primary health care attendance predicted subsequent utilization (β = 0.57; p < 0.001), along with caregiver availability (β = 0.12; p = 0.001) and prehospital emergency services hyper-demand (β = 0.08; p = 0.022). Super-utilizers were younger, had ≥4 comorbidities, polypharmacy, prior family medicine visits, home oxygen therapy, and lower substance or alcohol use. Conclusions: In multimorbid adults, prehospital emergencies demand is influenced by factors beyond severity, including comorbidities, polypharmacy, the use of home medical devices, caregiver availability, and primary health care utilization patterns. Strengthening coordination between prehospital emergencies and primary health care, promoting patient–caregiver education, and implementing early notification pathways may improve care continuity and reduce avoidable emergencies.

Background/Objectives: Accurate telephone triage of emergency medical cases plays a crucial role in improving outcomes for critically ill patients. Effective triage enables emergency medical dispatchers to provide appropriate pre-arrival instructions and to deploy operational units according to the patient’s severity level. This study aimed to develop and assess the content validity of the Emergency Medical Triage Protocol and Criteria-Based Dispatch Code (EMTP-CBDC) for Thailand. The objective was to ensure the tool’s content accuracy and applicability in prioritizing emergency responses in line with medical urgency, considering global changes and universal standards. Methods: A cross-sectional descriptive study was conducted from 15–30 April 2024. The content validity of the newly developed EMTP-CBDC, comprising 30 symptom groups, was evaluated by five emergency physician experts with at least 1 year of experience in emergency medical oversight. The assessment focused on four aspects: relevance, clarity, simplicity, and ambiguity. The Content Validity Index (CVI) was calculated at both the item level (I-CVI) and the scale level using the average index (S-CVI/Ave). To adjust for chance agreement, the probability of chance agreement (Pc) and the modified kappa coefficient (k*) were calculated for each item. Results: The content validation revealed I-CVI values ranging from 0.80 to 1.00 across all items. The S-CVI/Ave scores were 0.97 for relevance, 0.93 for clarity, 0.98 for simplicity, and 0.94 for ambiguity. These values surpassed the accepted thresholds for content validity. Conclusions: The EMTP-CBDC developed for Thailand demonstrated good content validity across relevance, clarity, simplicity, and ambiguity. Further studies are needed to establish its reliability and field performance before routine implementation. Full article

Emergency medical services confront significant challenges in delivering timely patient assessments within geographically isolated or disaster-impacted regions. While drones (unmanned aircraft systems, UAS) show transformative potential in healthcare, standardized protocols for drone-assisted patient evaluations remain underdeveloped. This study introduces the ABCD-IN-BARS protocol, a 9-step telemedicine checklist integrating patient-assisted maneuvers and drone technology to systematize remote emergency assessments. A wait-list randomized controlled trial with 68 first-aid-trained volunteers evaluated the protocol’s feasibility. Participants underwent web-based modules and in-person simulations and were randomized into immediate training or waitlist control groups. The ABCD-IN-BARS protocol was developed via a content validity approach, incorporating expert-rated items from the telemedicine literature. Outcomes included time-to-assessment, provider confidence (Modified Cooper–Harper Scale), measured at baseline, post-training, and 3-month follow-up. Ethical approval and informed consent were obtained. Most of the participants can complete the assessment with a cue card within 4 min. A mixed-design repeated measures ANOVA assessed the effects of Time (baseline, post-test, 3-month follow-up within subject) on assessment durations. Assessment times improved significantly over three time points (p = 0.008), improving with standardized protocols, while patterns were similar across groups (p = 0.101), reflecting skill retention at 3 months and not affected by injury or not. Protocol adherence in simulated injury identification increased from 63.3% pre-training to 100% post-training. Provider confidence remained high (MCH scores: 2.4–2.7/10), and Technology Acceptance Model (TAM) ratings emphasized strong Perceived Usefulness (PU2: M = 4.48) despite moderate ease-of-use challenges (EU2: M = 4.03). Qualitative feedback highlighted workflow benefits but noted challenges in drone maneuvering. The ABCD-IN-BARS protocol effectively standardizes drone-assisted emergency assessments, demonstrating retained proficiency and high usability. While sensory limitations persist, its modular design and alignment with ABCDE principles offer a scalable solution for prehospital care in underserved regions. Further multicenter validation is needed to generalize findings. Full article

Objectives: The primary objective was to compare the usage of Hazardous Materials (HazMat) Protective Personal Equipment (PPE) and ordinary PPE when performing basic and advanced health care support maneuvers in a prehospital setting, evaluating the effectiveness of several procedures, defined as the mean success rate of each. The secondary objective was to evaluate the presence of a learning effect, with improvements in the success rate and/or procedure timing. Methods: This was a prospective within-subjects (repeated-measures) study conducted on Emergency Medical Services (EMS) responders within their Chemical-Biological-Radiological-Nuclear-Explosive (CBRNe) training institutional programme. Volunteers performed a trial sequence of eight lifesaving procedures four times. During the first trial sequence, they wore standard clothing; during the three successive trials, they wore full HazMat PPE equipment. The primary outcomes were changes in success rate and time interval across the four trials. Results: A total of 146 EMS responders volunteered for the experiment. Procedure success rates remained high overall, with the most notable initial drop observed for video-assisted intubation (≈−10%). The only statistically significant delay in the first HazMat trial compared with baseline was for intravenous access (median +30 s; p < 0.001). In the two successive HazMat trials, success rates and timings improved, with median values coming close to baseline. However, only 61% of participants completed the entire drill due to tolerance limits of the equipment. Conclusions: HazMat PPE, while physically and ergonomically demanding, has minimal impact on most lifesaving procedures, though it may reduce intubation success and delay intravenous access. Tolerance to prolonged use is a key limitation, but dexterity improves rapidly with brief practice. EMS responders can benefit from continuous training practice, while manufacturers could explore ergonomic and tolerance improvements in their PPE equipment. Full article

Background: The emergency medical services (EMS) sector, as a complex system, presents substantial hurdles in providing excellent treatment while operating within limited resources, prompting greater adoption of artificial intelligence (AI) as a tool for improving operational efficiency. While AI models have proved beneficial in healthcare operations, there is limited explainability and interpretability, as well as a lack of data used in their application and technological advancement. Methods: The scoping review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for scoping reviews, using PubMed, IEEE Xplore, and Web of Science, with a procedure of double screening and extraction. The search included articles published from 2018 to the beginning of 2025. Studies were excluded if they did not explicitly identify an artificial intelligence (AI) component, lacked relevance to emergency department (ED) or prehospital contexts, failed to report measurable outcomes or evaluations, or did not exploit real-world data. We analyzed the data source used, clinical subclasses, AI domains, ML algorithms, their performance, as well as potential roles for large language models (LLMs) in future applications. Results: A comprehensive PRISMA-guided methodology was used to search academic databases, finding 1181 papers on prehospital emergency treatment from 2018 to 2025, with 65 articles identified after an extensive screening procedure. The results reveal a significant increase in AI publications. A notable technological advancement in the application of AI in EMS using different types of data was explored. Conclusions: These findings highlighted that AI and ML have emerged as revolutionary innovations with huge potential in the fields of healthcare and medicine. There are several promising AI interventions that can improve prehospital emergency care, particularly for out-of-hospital cardiac arrest and triage prioritization scenarios. Implications for EMS Practice: Integrating AI methods into prehospital care can optimize the use of available resources, as well as triage and dispatch efficiency. LLMs may have the potential to improve understanding and assist in decision-making under pressure in emergency situations by combining various forms of recorded data. However, there is a need to emphasize continued research and strong collaboration between AI experts and EMS physicians to ensure the safe, ethical, and effective integration of AI into EMS practice.

Background/Objectives: This study aimed to evaluate a regional implementation project for rural emergency care (RuralRescue) and to examine how its components and outcomes may support personalized approaches in emergency medicine. While not originally designed as a personalized medicine intervention, the project combined digital, educational, and organizational innovations that enable patient-specific adaptation of care processes. Methods: Conducted in the rural district of Vorpommern-Greifswald (Mecklenburg–Western Pomerania, Germany), the intervention included (1) standardized cardiopulmonary resuscitation (CPR) training for laypersons, (2) a geolocation-based first responder app for medically trained volunteers, and (3) integration of a tele-emergency physician (TEP) system with prehospital emergency medical services (EMSs). A multi-perspective pre–post evaluation covered medical, economic, and organizational dimensions. Primary and secondary outcomes included bystander CPR rates, responder arrival times, telemedical triage decisions, diagnostic concordance, hospital transport avoidance, economic simulations, workload, and technology acceptance. Results: Over 12,600 citizens were trained in CPR and the responder app supported early intervention in hundreds of cases. TEPs remotely assisted 3611 emergency calls, including delegated medication in 17.8% and hospital transport avoidance in 24.3% of cases. Return of spontaneous circulation (ROSC) after out-of-hospital cardiac arrest (OHCA) was achieved in 35.6% of cases with early CPR. Diagnostic concordance reached 84.9%, and documentation completeness 92%. Centralized coordination of TEP units reduced implementation costs by over 90%. Psychological evaluation indicated variable digital acceptance by role and experience. Conclusions: RuralRescue demonstrates that digitally supported, context-aware, and regionally integrated emergency care models can contribute significantly to personalized emergency medicine and can be cost-effective. The project highlights how intervention intensity, responder deployment, and treatment decisions can be tailored to patient needs, professional capacity, and regional structures—even in resource-limited rural areas.

Background/Objectives: Ultrasonography is a diagnostic modality characterized by high sensitivity in detecting hepato-biliary pathology, particularly intrahepatic biliary duct dilation. This study compares the sonographic findings obtained by a radiographer/sonographer in a Basic Emergency Service (BES) using Point-of-Care Ultrasonography (POCUS) in Portugal with the sonographic findings from the same patients acquired by radiologists at a referral hospital (RH) for suspected intrahepatic biliary dilatation. Methods: Nineteen patients presenting with right upper quadrant (RUQ) pain and suspected abdominal pathology underwent sonographic screening using POCUS in the BES. Subsequently, the same patients were referred to the RH, where a radiologist performed a comprehensive ultrasound. Both examinations were compared to determine whether the findings obtained in the BES were confirmed by radiologists in the RH. Results: Cholestasis, cholangitis, lithiasis, pancreatitis, peri-ampullary lithiasis, and neoplasms were observed in association with intrahepatic biliary dilation in this study sample. All six variables showed a strong association between the BES and RH findings (Cramer’s V > 0.6; p < 0.006). A strong kappa measure of agreement between the radiographer and radiologist findings was obtained in “cholelithiasis/sludge/gallbladder acute sonographic changes” (k = 0.802; p = 0.000). A moderate kappa value was obtained for the variable “abdominal free fluid”, (k = 0.706; p = 0.001). Conclusions: In this study, all patients referred from the BES to the RH required hospitalization for treatment and additional imaging exams. Although pre-hospital screening ultrasound is not intended for definitive diagnoses, the early detection of intrahepatic biliary tract dilatation through screening sonography played a significant role in the clinical referral of patients, with a sensitivity of 94% and specificity of 75%.

Background/Objectives: Pain remains as a prevailing cause, prompting patients to seek medical attention, comprising approximately 40% of all emergency department (ED) visits annually. Timely and effective pain management is crucial for patient comfort, satisfaction, and optimal recovery. However, there is increasing evidence highlighting the concern that patients often receive inadequate pain management in both emergency departments and prehospital settings. Despite the simplicity and potential for the repetitive use of pain scales throughout a patient’s stay, it appears that a greater emphasis is often placed on monitoring hypotension or low saturation values rather than addressing pain levels above 7 on the numeric rating pain scale. Methods: This article represents an ambitious attempt to implement process improvement methodologies such as Lean Management and SixSigma, both which have been well established in service and industrial fields, within the hospital environment to improve the process of pain management in the emergency department. Results: The implementation of pain management improvement processes in the emergency department led to a statistically significant but clinically modest increase in the administration of analgesics and improved pain reporting practices. The percentage of patients receiving no analgesia decreased from 96.6% to 94.8% (p = 0.008), and the documentation of pain characteristics during triage improved. However, the escalation of pain therapy remained limited, and strong analgesics were still underutilized. Conclusions: Despite partial improvements, the lean management-based interventions did not sufficiently address the problem of oligoanalgesia in the emergency setting. Sustainable change requires enhanced clinical engagement, ongoing staff training, and the broader adoption of structured analgesia protocols across prehospital and hospital care. Full article

Background: Respiratory infections (RIs) are a common cause of care by Prehospital Emergency Medical Services (PEMS). Early Warning Scores (EWS) are tools used by PEMS to assess patients with acute pathology. However, there is little evidence of their application in RIs. The primary aim of this study was to assess the ability of five EWS to predict one-year mortality (M1Y) and two-year (M2Y) mortality in patients with suspected RI assisted by PEMS. The secondary objective was to perform a survival analysis. Methods: An observational and prospective study was conducted in adult patients with RIs transferred by EMS to their referral hospital. The variables necessary for the calculation of EWS [National Early Warning Score 2 (NEWS2), Quick Sequential Organ Failure Assessment (qSOFA) score, Quick COVID-19 Severity Index (qCSI), CURB-65 Score for Pneumonia Severity (CURB-65) and BAP-65 Score for Acute Exacerbation of COPD (BAP-65) score] were collected. The prognostic ability of the EWS was assessed by the area under the receiver operating characteristic curve (AUC). Patients were followed up and a survival study was performed. Results: A total of 819 patients met the inclusion criteria. M1Y was 55.9% and M2Y was 63.5%. BAP-65 showed the best predictive ability at both 1 and 2 years, with AUC of 0.716 and 0.711, respectively. 48.8% of deaths took place during the first month. Conclusions: BAP-65 was the score with the best ability to predict both M1Y and M2Y after the index event in patients with RIs. All other EWS analyzed showed poor performance except in patients with low comorbidity. Full article

This sought seeks to find and examine the main stress factors and psychosocial settings that affect ambulance staff, looking at the larger problem of how these stressors impact their mental well-being and work satisfaction. The research collected data from a field survey that identified and assessed stress factors, as well as qualitative insights from interviews that examined staff perceptions of complex work conditions in emergency services. Important findings show that high-stress situations, like dealing with traumatic events, long hours, and insufficient support, are linked to higher anxiety and burnout in ambulance workers. Moreover, the study points out important features of the work environment, such as workplace relationships and organizational culture, that can either reduce or increase stress. These findings are important, as they could guide healthcare policies that seek to improve the well-being of emergency service workers, which is crucial for maintaining a strong and effective workforce in pre-hospital care. By stressing the urgent need for effective approaches and supportive work structures, this research can have wider implications for healthcare, indicating that tackling the psychosocial issues faced by ambulance staff is crucial not just for their own well-being but also for the overall quality of emergency medical services.

The organizational culture significantly impacts employee behavior, satisfaction, and retention. Historically associated with hierarchical, fire-service-based structures, EMS cultures vary considerably, and their influence remains unclear. We aimed to identify organizational cultures within EMS agencies and examine their association with clinicians’ intent to leave within 12 months. We performed a cross-sectional survey of nationally certified civilian EMS clinicians aged 18–85 in the United States who recertified with the National Registry of Emergency Medical Technicians between October 2022 and April 2023. Respondents completed the validated Organizational Culture Assessment Instrument (OCAI), categorizing organizational cultures into adhocracy, clan, hierarchy, market, or mixed. Multivariable logistic regression evaluated the organizational culture and clinicians’ intention to leave, adjusting for personal demographics, workplace characteristics, and job satisfaction. In total, 30,762 survey respondents were included. Mixed and hierarchy cultures predominated, followed by clan, market, and adhocracy. Clinicians in adhocracy and hierarchy cultures had significantly higher adjusted odds of intending to leave EMS compared to clan and mixed. The organizational culture in EMS significantly influences clinicians’ intentions to leave. Adhocracy, hierarchy, and market cultures are associated with an increased likelihood of turnover, but clan-oriented environments do not increase risks. These findings suggest that optimizing EMS agency cultures towards collaboration and supportive environments may enhance clinician retention. Full article

Recent major disasters, including the COVID-19 pandemic and floods in Europe, highlight the unpredictability of crises and the necessity for systemic preparedness at all levels of crisis management, including pre-hospital emergency medical services. Paramedics observed, under these challenging conditions (but not exclusively during them), cases of insufficient knowledge and skills in providing pre-hospital medical care, which lead to inadequate or prolonged decision making in delivering assistance. For this reason, the authors aimed to determine the extent to which such situations occur and to examine their causes, focusing on potential gaps and shortcomings in the education of paramedics. This study examines the impact of educational systems on the professional preparedness of paramedics in V4 European countries (the Slovak Republic, the Czech Republic, Hungary, and Poland) during pre-hospital care through a questionnaire survey. A survey involving over 1600 respondents revealed significant disparities in perceived knowledge and skill gaps, with Poland demonstrating the highest deficiencies (78%) and the Slovak Republic the lowest (57%). Key factors influencing these gaps included the frequency of external educational and training activities, years of experience, and expertise in managing critical conditions. The findings underscore the importance of innovative technologies, such as simulations and virtual reality, in enhancing paramedic training, along with integrating digital solutions across all phases of disaster management. Recommendations focus on strengthening system resilience, fostering interdisciplinary approaches, and improving system sustainability and adaptability. By using the results obtained and leveraging technological advances, the study aims to contribute to more effective crisis preparedness, population protection, and sustainable development goals (SDGs), namely (3, 4, 9, and 11), especially in the field of crisis management. This reinforces the broader role of SDGs in building more robust, future-ready disaster management frameworks. Full article

Background: The World Health Organization (WHO) estimates that 180,000 patients die from burns every year, which is considered a serious public health issue. Patients with burns require immediate pre-hospital care and transport to specialized treatment facilities. The aim of this study was to outline the profile of the burn patient from the perspective of the Polish Medical Air Rescue (PMAR), as well as to analyze the medical procedures being implemented. Methods: The study includes 2154 interventions by air emergency medical teams (AEMS) which provided aid for burn patients. The analysis covered the period from 2018 to 2022, including nationwide data made available from the IT systems of the PMAR. Statistical design was used, allowing for correlations of variables, at a significance level of p < 0.05. Results: Patients’ ages ranged from 1 month to 96 years (mean 35.05; SD ± 26.88). Adult patients (n = 1409; 65.41%) constituted the vast majority. The number of interventions to children below 1-year-old was noticeable (n = 394; 18.29%). Men were the most likely to suffer burns, up to three times more often than women (n = 1574, 73.07% vs. n = 570, 26.46%. T29—burns to multiple body areas (n = 890)—and T21—burns to the trunk (n = 255)—were most frequently reported as diagnoses according to the ICD-10 classification. A statistically significant association was found between age group and ICD-10 diagnosis (p < 0.001). The vast majority of patients were transported from the scene directly to Burn Treatment Centers (n = 1373; 63.74%). Treatment of pain by helicopter emergency medical services (HEMS) crews appeared to be effective (p < 0.001), and other interventions consisted of administering medications—ketamine (23.72%), rocuronium bromide (15.78%), propofol (14.02%)—and procedures such as sedation (30.87%), as well as intubation (13.42%) and mechanical ventilation (13.23%). Conclusions: The burn patient profile indicates men with a mean age of 35 years. Nevertheless, HEMS crews often carry out missions to infants and newborns. The most common diagnosis was extensive body burns. In 63.74% of the missions, patients were transported to the Burn Treatment Center. The HEMS crews implement effective pharmacological analgesia, and handle rescue medications and procedures to stabilize the patient’s condition. Full article
