How prehospital emergency personnel manage ethical challenges: the importance of confidence, trust, and safety.

Ethical challenges constitute an inseparable part of daily decision-making processes in all areas of healthcare. Ethical challenges are associated with moral distress that can lead to burnout. Clinical ethics support has proven useful to address and manage such challenges. This paper explores how prehospital emergency personnel manage ethical challenges. The study is part of a larger action research project to develop and test an approach to clinical ethics support that is sensitive to the context of emergency medicine. We explored ethical challenges and management strategies in three focus groups, with 15 participants in total, each attended by emergency medical technicians, paramedics, and prehospital anaesthesiologists. Focus groups were audio-recorded and transcribed verbatim. The approach to data analysis was systematic text condensation approach. We stratified the management of ethical challenges into actions before, during, and after incidents. Before incidents, participants stressed the importance of mutual understandings, shared worldviews, and a supportive approach to managing emotions. During an incident, the participants employed moral perception, moral judgments, and moral actions. After an incident, the participants described sharing ethical challenges only to a limited extent as sharing was emotionally challenging, and not actively supported by workplace culture, or organisational procedures. The participants primarily managed ethical challenges informally, often using humour to cope. Our analysis supports and clarifies that confidence, trust, and safety in relation to colleagues, management, and the wider organisation are essential for prehospital emergency personnel to share ethical challenges and preventing moral distress turning into burnout.

Organizational resilience in first-response agencies: Visual responses from first responders during the COVID-19 pandemic

Organizational resilience is considered essential not only for the survival of organizations but also for bouncing back from adversity and maybe even thriving in the aftermath of a crisis. While much is known about organizational resilience in different types of high-risk professions, less is known about the development and impact of organizational resilience within public first-response organizations. First responders are constantly coping with emergency situations and, therefore, must continually assess and reassess organizational resilience. To address this gap, this study explores the management of first-response organizations during the COVID-19 pandemic. Using visual methods and qualitative interviews with firefighters, police officers, emergency medical technicians, and paramedics working in the U.S. during the height of the COVID-19 pandemic, this study examines the impact of the internal and external context as well as specific organizational capabilities on the challenges and opportunities for organizational resilience. Common challenges impacting organizational resilience include inaction, inconsistent decontamination procedures, and a lack of perceived community support. Opportunities for promoting organizational resilience in first-response agencies include consolidating information, using equipment creatively, balancing protocol and patient needs, and sharing personnel and resources.

Informal Peer Support and Intentional Acts of Kindness May Attenuate the Impact of Work-Related Stressors on Compassion Satisfaction, Secondary Traumatic Stress, and Burnout of Emergency Medical Services Clinicians

ObjectiveEmergency medical services (EMS) Code Lavender was developed to support EMS clinicians after stressful events via consistent recognition of events, informal peer support, and intentional acts of kindness. This study evaluated changes in burnout screening tool responses of EMS clinicians in response to program implementation and the coincidental start of coronavirus disease 2019. MethodsAnonymous surveys with demographic questions and 2 burnout screening tools were distributed before program implementation (spring 2020) and 20 months later (fall 2021). Analysis included t-tests, Fisher exact tests, and multivariable linear regression. ResultsSeventy-seven preprogram (59% response rate) and 108 intraprogram (88% response rate) survey responses were included. No changes existed between preprogram and intraprogram responses across all subscale scores. Sex was associated with depersonalization subscale scores, with men having scores 1.53 (95% confidence interval [CI] 0.11-2.95) higher than women. Compared with emergency medical technicians, paramedics had higher compassion satisfaction (OR 3.50; 95% CI 1.79-5.70) and personal accomplishment scores (OR 2.40; 95% CI 1.08-3.71). Transport nurses had higher personal accomplishment (OR 3.29; 95% CI 1.18-5.40), depersonalization (OR 3.73; 95% CI 1.19-6.26), and rates of burnout symptoms (OR 0.54; 95% CI 0.09-0.98) than emergency medical technicians. ConclusionThe organizational commitment, peer support, and authentic leadership of EMS Code Lavender may attenuate work-related stressors among EMS clinicians.

THE MEDIATING ROLE OF JOB SATISFACTION AND PRESENTEEISM IN THE RELATIONSHIP BETWEEN JOB STRESS AND TURNOVER INTENTION: AN APPLICATION IN FAMILY HEALTH CENTRES

In this study, it was aimed to examine the relationship between job stress and turnover intention and the mediating effects of presenteeism and job satisfaction in this relationship. The research was conducted on healthcare professionals working in family health centres in Erzincan province and a total of 163 people, including 68 physicians, 34 nurses, 37 midwives and 24 other healthcare professionals (laboratory, emergency medical technician, etc.) were reached. The questionnaire method was used as a data collection tool in the study. The data were analysed using SPSS 25.0 program with PROCESS Macro 4.1 plug-in and the SPSS 24.0 AMOS program. Mediation analysis was performed using the Bootstrap method at 95% confidence interval. As a result of the analysis, it was determined that job stress has a significant positive effect on turnover intention and presenteeism variables and a significant negative effect on the job satisfaction variable. In addition, it was found that presenteeism had a positive effect on turnover intention and job satisfaction had a negative effect on turnover intention. Finally, it was concluded that the relationship between job stress and turnover intention is mediated by presenteeism and job satisfaction.

Identifying trusted local sources and predicting behavior change pathways according to COVID-19 vaccination status: Results of a 2022 statewide survey of Alaskan adults

BackgroundLow rates of COVID-19 vaccination remain a substantial public health challenge. Despite early successes, vaccinations of Alaskans trail the US average, drawing attention to the need for better-designed and targeted vaccine confidence interventions. Our objective was to assess levels of community trust and theory-driven predictors of vaccination status to inform the design of future programs. MethodsWe conducted a cross-sectional, telephone-based survey of 940 Alaskan adults between May and June 2022. Data were collected on vaccination status (including initial vaccination and receipt of booster shots), trust in local community members, demographic characteristics, and thematic questions designed using the Capability, Opportunity, Motivation - Behavior (COM-B) model to examine possible predictors (barriers/facilitators) of vaccination status. FindingsAmong those who are not fully vaccinated and boosted, we observe significantly lower trust placed in many immediate community members, especially health workers (e.g., doctors, nurses, specialty care physicians, health administrators). Firefighters and emergency medical technicians enjoy the most community trust, followed by medical professionals. Among those who received only a primary vaccine series, we find that perceptions of whether close friends are vaccinated, a sense of professional responsibility, and age were the strongest predictors vaccination status. Among the unvaccinated, we find significant predictive power from the same variables, as well as perceptions of whether family members are vaccinated, perceived risks from non-vaccination and whether vaccination is a healthy choice. ConclusionsThese findings will help inform the design and targeting of future vaccine promotion interventions to adult populations in Alaska. Interventions that leverage reflective motivation and social opportunity domains of the COM-B framework may be most effective. Local community members including firefighters and emergency medical technicians, as well as medical professionals may be perceived as the most trustworthy and influential messengers among those who are not fully vaccinated and boosted.

Emotional burnout, job satisfaction, and intention to leave among pre-hospital emergency healthcare workers during the COVID-19 pandemic.

With the onset of the COVID-19 pandemic, pre-hospital emergency healthcare workers (PHEHW) assumed critical responsibilities in controlling and preventing the spread of the virus. This descriptive study aimed to explore the emotional burnout, job satisfaction, and intention to leave among PHEHW during the COVID-19 pandemic. The study was conducted with 401 emergency medical technicians and paramedics. The Sociodemographic Data Form, the Emotional Burnout Scale, the Job Satisfaction Scale, the Intention to Leave the Profession Scale were used to collect data. The findings were assessed with a significance level set at p < 0.05 and a 95% confidence interval. The participants demonstrated moderate scores in emotional burnout, job satisfaction, and intention to leave the profession. The analysis revealed a negative correlation, indicating that as emotional burnout increased, job satisfaction decreased, and the intention to leave the profession heightened. Notably, the participants who had 6-9 years of service, lacked knowledge about COVID-19, had no COVID-19 training, underwent COVID-19 testing, and experienced the loss of a healthcare worker due to COVID-19 exhibited higher levels of burnout. Furthermore, those who had 6-9 years of service, lacked knowledge about COVID-19, had no COVID-19 training, and lost a healthcare worker due to COVID-19 reported lower levels of job satisfaction. Additionally, participants who had 6-9 years of service, lacked knowledge about COVID-19, had no COVID-19 training, and experienced the loss of a healthcare worker due to COVID-19 displayed a greater intention to leave the profession. It is important to implement improvement initiatives that will increase the motivation and job satisfaction of PHEHW. These include the regulation of working hours and shifts, augmenting staff numbers, enhancing working conditions, improving salaries, and implementing strategies aimed at fostering motivation and job satisfaction.

(Un)ergonomic working conditions for a paramedic in a medical ambulance

The work of a paramedic, is characterised by a high risk of injury. Ergonomic, psychological, and biomechanical factors are considered risk factors in the profession of emergency medical technicians. Ensuring ergonomic working conditions for emergency medical technicians is a priority and requires a thorough assessment both in the design process and during the operation of the ambulance, to provide a diagnosis of the current state and present necessary recommendations for modernization. Identifying stressors will enable the design of an ergonomic interior for the ambulance, ensuring comfort and reliability for members of the emergency medical team, thereby reducing the risk of injuries. The authors of this article developed a comprehensive methodology for assessing the nuisances occurring during the paramedic's work, which required specialised preliminary research. The research included the measurement and analysis of the paramedic's movement kinematics during typical medical procedures, both at a standstill and while driving the ambulance. For the analysis of motion kinematics, a non-invasive method called myoMotion was employed, and the study was conducted in a Mercedes ambulance. This article contains preliminary results on the evaluation of movement kinematics. These demonstrated the necessity for the paramedic to adopt forced positions when performing medical procedures. The ranges of movement of the individual body parts of the paramedic deviated from accepted norms, resulting in musculoskeletal overload. The acquired knowledge forms the basis for a detailed analysis of tasks performed within each procedure from the perspective of the spatial structure of the ambulance, the arrangement of equipment and medical supplies, their accessibility during work, and the organization of work within the ambulance. Additional identification of musculoskeletal system stress, its sources, and the formulation of modification recommendations for the ambulance interior will enable ensuring the comfort and reliability of the work for emergency medical teams, thereby reducing the risk of injuries in the workplace.

Influence of Personal and Work Environments on Work-Life Balance Among Emergency Medical Technicians.

Introduction Work-life balance (WLB) is a critical concern for emergency medical technicians (EMTs) because it significantly affects the provision of comprehensive emergency medical services (EMS). This study investigated personal and work-related factors influencing work-to-family negative spillover (WFNS), a key element of WLB, among EMTs. Methods A web-based survey was conducted from July 26 to September 13, 2021, among EMTs in Hokkaido, Japan. The study included 21 facilities that were randomly selected from 42 fire stations. The Japanese version of the Survey Work-Home Interaction-NijmeGen (SWING-J) was used to measure WFNS. Personal background factors, such as age, sex, years of work experience, and education, were surveyed. We also evaluated work environment factors, such as weekly working hours, monthly night shifts, monthly overtime hours, and yearly paid vacation days. Unpaired Student's t-tests, one-way analysis of variance (ANOVA), and multilevel generalized linear model (MGLM) analyses were used to explore the relationships between WFNS and personal and work-related factors. Results A total of 912 respondents were included in our analysis. They were predominantly male (98.2%), with an average EMT work experience of 12.7 years and a mean WFNS score of 1.16 (standard deviation (SD) = 1.67). MGLM analysis, adjusting for covariates, identified years of work experience (β = -0.129, p = 0.001), monthly overtime hours (β = 0.184, p < 0.001), and yearly paid vacation days (β = -0.170, p < 0.001) as independent factors associated with WFNS. Conclusion This study suggested that adjusting WFNS among EMTs could be achieved by reducing overtime hours and fostering an organized approach to paid leave within the work environment.

Hyperventilation During Manual Ventilation Can Be Reduced Using a Novel Ventilator but Not With Education Interventions.

Traumatic brain injury (TBI) is the leading cause of combat casualties in modern war with an estimated 20% of casualties experiencing head injury. Since the release of the Brain Trauma Foundation's Guidelines for the Management of Severe Traumatic Brain Injury in 1995, recommendations for management of TBI have included the avoidance of routine hyperventilation. However, both published and anecdotal data suggest that many patients with TBI are inappropriately ventilated during transport, thereby increasing the risk of morbidity and mortality from secondary brain injury. Enlisted Air Force personnel with prior emergency medical technician training completing a 3-week trauma course were evaluated on their ability to provide manual ventilation. Participants provided manual ventilation using either an in-situ endotracheal tube (ETT) or standard face mask on a standardized simulated patient manikin with TBI on the first and last days of the course. Manual ventilation was provided via a standard manual ventilator and a novel manual ventilator designed to limit tidal volume (VT) and respiratory rate (RR). Participants were given didactic and hands-on training on the third day of the course. Half of the participants were given simulator feedback during the hands-on training. All students provided 2 minutes of manual ventilation with each respirator. Data were collected on the breath-to-breath RR, VT, and peak airway pressures generated by the participant for each trial and were averaged for each trial. A minute ventilation (MV) was then derived from the calculated RR and VT. One hundred fifty-six personnel in the trauma course were evaluated in this study. Significant differences were found in the participant's performance with manual ventilation with the novel compared to the traditional ventilator. Before training, MV with the novel ventilator was less than with the traditional ventilator by 2.1 ± 0.4 L/min (P = .0003) and 1.6 ± 0.5 L/min (P = .0489) via ETT and face mask, respectively. This effect persisted after training with a difference between the devices of 1.8 ± 0.4 L/min (P = .0069) via ETT. Both traditional education interventions (didactics with hands-on training) and simulator-based feedback did not make a significant difference in participant's performance in delivering MV. The use of a novel ventilator that limits RR and VT may be useful in preventing hyperventilation in TBI patients. Didactic education and simulator-based feedback training may not have significant impact on improving ventilation practices in prehospital providers.

Rural Emergency Medical Services Clinicians’ Perceptions and Preferences in Receiving Clinical Feedback From Hospitals: A Qualitative Needs Assessment

Objective Emergency medical services (EMS) clinicians experience dissatisfaction with the quality and quantity of clinical feedback from hospitals. Satisfaction is further diminished by the lack of a standardized systems approach. The purpose of this study was to identify rural clinicians’ perceptions and preferences regarding clinical feedback received from hospitals, the delivery mechanisms, and its impact on their relationships with health care organizations. Methods This was a qualitative study focused on EMS clinicians involved in rural prehospital care at a single Midwestern academic medical center. Using a phenomenological framework, semi-structured interviews were conducted with medical directors, service directors, fire captains, air medical personnel, emergency medical responders, emergency medical technicians, advanced emergency medical technicians, and paramedics, all of whom were selected through purposive sampling. Interviews were recorded, transcribed, and independently coded by two trained reviewers. Results Twenty participants (11 frontline clinicians and 9 administrative staff members) with a wide range of clinical experience from 14 air and ground EMS agencies were interviewed. Emerging themes included: (1) the value or usefulness of feedback; (2) desired feedback system characteristics; (3) barriers to receiving feedback; (4) utilization and application of feedback; and (5) the feedback’s impact on the relationship with health care organizations. Participants felt that clinical feedback from hospitals was especially important as a method of improving quality of care, though was rarely provided. Professional development was seen as a major benefit of receiving clinical feedback from hospitals. Conclusion Our results suggest that consistent clinical feedback provided by hospitals was valued. Establishing a culture of providing organized feedback to practicing rural EMS clinicians is important for professional development and can strengthen the relationships between EMS clinicians and hospitals. These study findings can assist in the development and implementation of a standardized feedback instrument to benefit rural EMS clinicians, patients, and the health care system as a whole.

Assessing the efficacy of simulation-based education for paramedics in extended focused assessment with sonography for trauma under physician guidance

We investigated the effectiveness of simulation-based education in Focused Assessment with Sonography for Trauma (FAST) to increase the number of Emergency Medical Technicians (EMTs) capable of performing ultrasound examinations in vehicles under the guidance of a physician. Twenty-eight paramedics watched a 14-min video on the features of the ultrasound system, its use, and the scanning method for each part of the body. Each participant performed four FAST examinations using a portable ultrasound device, and the task performance was rated using the Task Specific Checklist (TSC) and Global Rating Scale (GRS). The time required for visualizing each examination site and each FAST was assessed. The mean time required for the first and fourth FAST was 144.6 ± 52.4 s and 90.5 ± 31.0 s, respectively. The time required for each test significantly decreased with repeated testing (p < 0.001). The time to complete FAST was significantly shortened for the pericardial cavity (33.4 ± 23.1/15.3 ± 10.6 s, p < 0.01), right thoracic cavity (25.2 ± 11.8/12.1 ± 8.3 s, p < 0.01), Morrison fossa (19.1 ± 10.8/10.8 ± 6.3 s, p < 0.05), and left thoracic cavity (19.0 ± 8.3/15.6 ± 8.3 s, p < 0.05). TSC and GRS scores were elevated, and all EMTs could obtain valid images. The combination of a brief video lecture and hands-on training significantly reduced the time required for FAST performance. Moreover, repeated practice enabled the EMTs to efficiently obtain accurate and clinically useful images.

Optimization of the stroke hospital selection strategy and the distribution of endovascular thrombectomy resources.

Nowadays, emergency medical technicians (EMTs) decide to send a suspected stroke patient to a primary stroke center (PSC) or to an endovascular thrombectomy (EVT)-capable hospital, based on the Cincinnati Prehospital Stroke Scale (CPSS) and the number of symptoms a patient presents at the scene. Based on existing studies, the patient is likely to have a better functional outcome after three months if the time between the onset of symptoms and receiving EVT treatment is shorter. However, if an acute ischemic stroke (AIS) patient with large vessel occlusion (LVO) is first sent to a PSC, and then needs to be transferred to an EVT-capable hospital, the time to get definitive treatment is significantly increased. For this purpose, We formulate an integer programming model to minimize the expected time to receive a definitive treatment for stroke patients. We then use real-world data to verify the validity of the model. Also, we expand our model to find the optimal redistribution and centralization of EVT resources. It will enable therapeutic teams to increase their experience and skills more efficiently within a short period of time.

Neurological outcomes in traffic accidents: A propensity score matching analysis of medical and non-medical origin cases of out-of-hospital cardiac arrest

AimThis study aimed to comprehensively compare the characteristics of out-of-hospital cardiac arrest (OHCA) with medical and non-medical origins attributed to traffic accidents and explore the potential association between the cases with a medical origin and neurologically favorable outcomes. MethodsIn this retrospective nationwide population-based study, baseline data were collected between January 2018 and December 2020. We analyzed 5091 OHCA associated with traffic accidents on the road scene. Only those encounters involving treatment or transport by prehospital emergency medical technicians were included. The characteristics of OHCA incidents and their outcomes were analyzed by categorizing patients into “medical origin” and “non-medical origin” groups. ResultsMedical-origin cases exhibited several distinct characteristics, including higher frequencies of occurrence during the daytime (79.3% [706/890] vs. 68.9% [2895/4201], p < 0.001), a higher prevalence among male (77.8% [692/890] vs. 68.3% [2871/4201], p < 0.001) and younger patients (median [25–75%]: 63 years [42–77] vs. 66 years [50–76], p = 0.003), a higher proportion of shockable initial rhythms(10.5% [93/890] vs. 1.1% [45/4201], p < 0.001), an increased number of cases requiring advanced airway management (33.8% [301/890] vs. 28.5% [1199/4201], p = 0.002) and adrenaline administration by emergency medical teams (26.9% [239/890] vs. 21.7% [910/4201], p < 0.001), and shorter transport times (55.3% [492/890] vs. 60.9% [2558/4201], p = 0.002) compared to non-medical-origin cases. However, medical-origin cases also had lower witness rates (42.8% [381/890] vs. 27.2% [1142/4201], p < 0.001) and were less likely to be transported to higher-level hospitals (55.3% [492/890] vs. 60.9% [2558/4201], p = 0.002). Propensity score matching analysis identified factors associated with favorable neurological outcomes in medical-origin traffic accidents. The adjusted odds ratios were as follows: 8.46 (3.47–20.61) for cases with shockable initial rhythms, 2.36 (1.01–5.52) for cases involving traffic accidents due to medical origin, and 0.09 (0.01–0.67) for cases where advanced airway management was provided. ConclusionIn this retrospective study, the occurrence of OHCAs of medical origin involving traffic accidents were associated with favorable neurological outcomes. These cases more frequently demonstrated favorable factors for survival compared to those classified as of non-medical origin. The findings have important implications for public health and EMS professionals, they will guide future research aimed at optimizing prehospital care strategies and improving survival rates for similar cases.

Emergency medical services (EMS) clinicians' views on EMS-delivered interventions to promote secure firearm storage practices.

Lethal means safety counseling (LMSC) to promote secure firearm storage may reduce the risk of firearm-involved deaths, including suicide. We examined if emergency medical services (EMS) clinicians, including emergency medical technicians and paramedics, may be suitable LMSC messengers. We conducted a web-based survey of 229 US EMS clinicians. While few EMS clinicians supported EMS-delivered LMSC to all patients (17.0%), most supported EMS-delivered LMSC to patients in an acute suicidal crisis (64.2%) or with a known suicide attempt history (55.9%). Barriers to EMS-delivered LMSC included lack of training (73.4%), perceptions that LMSC is outside EMS clinicians' scope of practice (58.1%), and lack of standard operating procedures (56.3%). Most reported at least some interest in receiving training on EMS-delivered LMSC (67.7%). Participants holding more accurate beliefs about the link between firearm storage practices and suicide risk, as well as the efficacy of LMSC, were more likely to support EMS-delivered LMSC across patient scenarios (ORs = 2.18-5.21, ps <0.01) and express interest in receiving LMSC training (ORs = 3.78-5.43, ps <0.001). Given that many EMS clinicians interface with patients at elevated suicide risk, targeted LMSC training may be strategic; however, research is needed to determine if and how EMS clinicians might be viable LMSC messengers.

Emergency medical technicians' experience of managing patients' pain during hospital transport: A qualitative study

This study aimed to explore and elucidate the experiences of emergency medical technicians concerning the pain management of patients during hospital transfers. By delving into their feelings, thoughts, and attitudes, the study sought to provide valuable insights to address the challenges faced in this critical aspect of patient care. In this qualitative study, targeted sampling was employed to recruit 10 emergency medical technicians as participants. Data were gathered through interviews and subsequently transcribed onto paper. The collected information was then subjected to analysis using the conventional content analysis method. The analysis of the collected data and the resulting findings revealed the presence of several barriers, including limited options for pain management, concerns about drug side effects, fear of potential repercussions, and the lack of readily available medical support for emergency medical technicians. The study's findings highlight the multitude of barriers and challenges in managing patients' pain, underscoring the paramount importance of pain relief as a critical issue. This significance becomes even more apparent in underserved and remote regions with limited treatment resources, where emergency medical technicians must prioritize this matter as a vital concern.

Factors Predisposing Emergency Medical Technicians to Workplace Violence: A Cross Sectional Study.

Emergency medical technicians (EMT) are at high risk of workplace violence as they often care for patients in uncontrolled and often hostile emergency settings. Gauteng Province, the most populous province in South Africa, caters for 75% of the total population which is dependant on state funded health care. Public sector EMTs' have been robbed with aggravated circumstances, assaulted with intent to do grievous bodily harm, raped and even murdered whilst on duty. Despite this, comprehensive studies investigating the factors that predispose public sector EMTs' to workplace violence in Gauteng Province are lacking. Thus, the aim of this study was to investigate the factors that predispose public service EMTs' to workplace violence in Gauteng Province. Data were collected using questionnaires. A total of 413 questionnaires were returned by community members of Gauteng who met the inclusion criteria. Descriptive statistics and binomial tests were used to analyze data. The results of this study revealed that workplace violence toward public service EMTs' in Gauteng is attributed to the high rates of crime, the widening gap of inequality, economic deprivation of basic rights to previously disadvantaged communities by government, vulnerability of EMTs' when responding to the ill and injured within low- and middle-income communities and a lack of consequence for disorderly behavior within the communities. An understanding of the community factors that predispose EMTs' to workplace violence may improve the understanding of the phenomenon of workplace violence and developing prevention programs within the communities.

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

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. 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. 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. The digital STEMI biomarker, derived from printed prehospital ECGs, demonstrated non-inferiority to expert consensus, indicating a promising approach for enhancing prehospital telecardiology.

E-FAST Ultrasound Training Curriculum for Prehospital Emergency Medical Service (EMS) Clinicians.

Audience and type of curriculum: This hybrid, asynchronous curriculum is designed for prehospital clinician colleagues, including but not limited to emergency medical technicians (EMT), advanced EMTs (AEMT), EMT-paramedics (EMT-P), critical care EMT-Ps (CCEMTP), critical care transport nurses (CCTN), and certified flight registered nurses (CFRN) to learn and practice ultrasound fundamentals in the setting of a standardized extended focused assessment with sonography in trauma (E-FAST) exam. Over a five-month curriculum, learners will perform a pre-test, review online module lectures, attend an ultrasound scanning workshop, and perform post-test examinations. The extended-focused assessment with sonography in trauma (E-FAST) exam can identify intrathoracic and intraabdominal free fluid, as well as pneumothoraces. The E-FAST ultrasound exam has previously been taught to clinicians of various backgrounds in healthcare including emergency medical service (EMS). However, an open-access, systemized curriculum for teaching E-FAST exams to EMS clinicians has not been published. By the end of these training activities, prehospital EMS learners will be able to demonstrate foundational ultrasound skills in scanning, interpretation, and artifact recognition by identifying pertinent organs and anatomically relevant structures for an E-FAST examination. Learners will differentiate between normal and pathologic E-FAST ultrasound images by identifying the presence of free fluid and lung sliding. Learners will also explain the clinical significance and application of detecting free fluid during an E-FAST scan. The educational strategies used in this curriculum include a hybrid, asynchronous curriculum encompassing 2.5 hours of lectures derived from online learning modules and in-person review. In addition, learners will attend 2 hours of hands-on proctored ultrasound scanning practicing E-FAST examinations. An online 13-question pre-test was administered prior to the study. An online post-test and in-person scanning OSCEs were administered at least eight weeks after their scheduled workshop consisting of an online 13-question multiple-choice post-test, a confidence survey, and a hands-on E-FAST Objectively Structured Clinical Exam (OSCE) session. A non-parametric Wilcoxon signed-rank test was performed between each pre-test and post-test metric to examine the statistical differences of paired data. Post-test scores demonstrated statistically significant improvement in both image interpretation exams and ultrasound self-efficacy from the pre-test. The mean pre-test and post-test scores were 55.46% (7.21 ± 1.99) and 84.23% (10.89 ± 1.59) correct out of 13 questions, respectively (p < 0.0001). Participants surveyed an increase in self-efficacy reflected by a Likert scale for ultrasound usage and image interpretation (p < 0.005). The average post-test OSCE E-FAST exam score was 37.89 ± 2.76 out of 42 points (90.21%). This 4.5-hour hybrid asynchronous model demonstrates an effective curriculum for teaching E-FAST ultrasound to prehospital clinicians.

집단미술치료가 외상 후 스트레스를 경험한 응급구조사의 회복탄력성과 정서 조절 곤란에 미치는 효과

The purpose of this study was to investigate the effects of group art therapy on the resilience and emotional regulation difficulties of emergency medical technicians who experienced PTSD. The subjects were 7 emergency medical technicians working at the fire station located in the city D who experienced PTSD. The program of group art therapy was conducted once a week for 90 minutes per session, from May 1st, 2023, to August 31st, 2023, with a total of 14 sessions. As research tools, we quantitatively analyzed the pre- and post-changes using resilience scales and emotion regulation difficulties scales. Additionally, we qualitatively analyzed the changes in major content for each session using the Person in the Rain (PITR) drawing tests. The results of this study were as follows. Firstly, group art therapy had a positive effect on the resilience of emergency medical technicians who experienced PTSD. Secondly, group art therapy had a positive effect on the emotion regulation difficulties of emergency medical technicians who experienced PTSD. Thirdly, in the Person in the Rain (PITR) drawing tests, changes in emotional regulation, reduction of emotional instability, the establishment of a positive self-image, and improvement of stress-coping ability appeared. These research results lead to the conclusion that group art therapy has a positive effect on the resilience and emotion regulation difficulties of emergency medical technicians who experience PTSD. This suggests its potential utility in counseling and art therapy settings for emergency medical technicians.

*SMARTSIM* A multicenter prospective randomized trial of 3D virtual reality versus traditional patient simulation.

Simulations are an integral part of paramedic education. Technological advancements have introduced three-dimensional virtual reality patient simulations (3DVRS), offering a low-cost, accessible alternative. This study compares the impact of 3DVRS and traditional simulation on paramedic students. Students selected from a convenience sample of 11 cohorts in 10 accredited programs distributed across the United States were allocated to 2 groups using a stratified random sampling. One group received simulations via 3DVRS, the second used traditional in-person simulation. Students were exposed to 6 scenarios over 2h from the National Association of Emergency Medical Technicians (NAEMT) Advanced Medical Life Support (AMLS) program. Altered mental status scenarios were selected a priori by the research team containing approximately 30 potential differential diagnoses. A 50-item posttest was administered using validated cognitive items provided by Fisdap. A multicenter prospective randomized trial of 174 paramedic students was undertaken from April until August of 2022. The traditional simulation group was comprised of 88 students and the 3DVRS group had 86 students. A Mann-Whitney U test (U=4064.5, n 1=88, n 2=86, p=0.396) detected no statistical difference between two distributions or median exam score (70%), the range of values and interquartile range (IQR) for both groups: TS IQR=64-75 (range, 32-82); 3DVRS IQR=64-76 (range, 34-86). No difference in exam scores using 3DVRS versus traditional simulation was detected. Paramedic programs may have an effective new option when incorporating simulation with 3DVRS, potentially reducing financial and real-estate resources required with in-person simulations. Larger studies are needed to truly evaluate the impact and usability of virtual reality on paramedic education.
