Development and validation of assessment instruments for cervical collar and spinal board placement in simulated environments for nursing students in the care of polytrauma patients

BackgroundMultiple trauma injuries are the leading cause of death and disability in people under the age of 45 and require prompt and specialised care. However, medical and nursing education programmes do not always include specific training in emergency pre-hospital care, resulting in a lack of basic practical skills in trauma management.ObjectiveTo develop and validate two instruments for assessing nursing students’ competence in cervical collar and spinal board application in simulated pre-hospital emergency scenarios.MethodThis is an instrumental study that involves the development of two assessment instruments and the evaluation of their psychometric properties in a sample of 392 nursing students. Content validity was assessed using expert judgement, by calculating the content validity ratio (CVR) for each item and the scale level content validity index average (S-CVI/Ave) for the instruments. Exploratory factor analysis using the MINRES extraction method and Promax rotation was performed to analyse the performance of the items and structure of the rubrics. Internal consistency was analysed using the Omega coefficient and inter-rater agreement was assessed using Cohen’s Kappa coefficient.ResultsInitially, two rubrics were obtained: one with six items for cervical collar placement (S-CVI/Ave = 0.86) and one with nine items for spinal board placement (S-CVI/Ave = 0.81). Both had a single-factor structure, with all items having factor loadings greater than 0.34 for the cervical collar rubric and 0.56 for the spinal board rubric, except for item 2 of the cervical collar rubric (λ = 0.24), which was subsequently removed. The final cervical collar rubric (five items) had an overall internal consistency of 0.84 and the spinal board rubric had an overall internal consistency of 0.90, calculated using the Omega statistic. The weighted Kappa coefficient for each item ranged from acceptable (0.32) to substantial (0.79). These results show that we have successfully developed two sufficiently valid instruments to assess the immobilisation competencies proposed in the objective of the study.ConclusionWhilst further research is needed to fully establish their psychometric properties, these instruments offer a valuable starting point for evaluating nursing students' competence in cervical collar and spinal board application in simulated pre-hospital scenarios.

Occupational stress profiles of prehospital and clinical staff in emergency medicine-a cross-sectional baseline study.

Occupational stress among emergency medical staff remains a central problem. Prior to the COVID-19 pandemic, many studies were focused on the working conditions of clinical emergency staff, but few examined the occupational stress profiles of prehospital emergency dispatchers (ED). The aim of this study is therefore to provide baseline data on the differences in occupational stress profiles between prehospital and clinical emergency medical staff. ED, emergency nurses (EN), and trauma surgeons on duty (TS) were questioned using the established and validated standardized short version of the instrument for stress-related job analysis for hospital physicians (ISAK-K). Differences between occupational groups were compared using the Mann-Whitney U test. Our data indicate significant differences in perception of stressors between professional groups (p < 0.05), with ED showing the highest psychological stress, followed by EN. Social stressors and emotional dissonance were significantly higher in ED and EN compared to TS (p < 0.05). Time pressure was identified as major stressor for ED and TS, but not for EN (p < 0.01). All professions showed moderate high levels of uncertainty and frustration (p = n.s.). Support from colleagues and supervisors was the greatest positive resource for all professional groups (p = n.s.). In accordance with current literature, our results advocate for a re-evaluation of the identified stressors, as ED, EN, and TS continue to show high levels of occupational stress. Training programs for coping with emotional dissonance and social stressors are likely to be crucial for reducing job stress among ED and EN.

The effect of assessor visibility on student stress and anxiety in emergency care simulation assessments

BackgroundSimulation assessment can result in anxiety for students. These assessments involve being observed by assessors, so there is a significant socio-evaluative stress component which may cause greater anxiety if assessors are visible to students during assessments. The aim of this study was to determine the effect of assessor visibility on biological and physiological markers of stress and levels of anxiety experienced by pre-hospital emergency care students in a simulation assessment environment.MethodsA paired comparison, pre-post test research design was used with two conditions; an assessor visible condition with simulation assessors visible to students in the room and an assessor not visible condition with assessors not in the room but connected via video link. With a sample of 29 emergency care students anxiety was measured with the State-Trait Anxiety Inventory and stress was measured with salivary cortisol and heart rate variability (HRV).ResultsDifferences in state anxiety scores, HRV variables and salivary cortisol suggested lower stress and anxiety in the assessor visible group. Only heart rate was significantly different between the groups (p = 0.016), with a higher heart rate in the assessor not visible group.ConclusionsGreater stress and anxiety may be experienced by students during emergency care simulation assessments when assessors are not visible to students.

Inhaled analgesics for the treatment of prehospital acute pain-A systematic review.

Many prehospital emergency patients receive suboptimal treatment for their moderate to severe pain. Various factors may contribute. We aim to systematically review literature pertaining to prehospital emergency adult patients with acute pain and the pain-reducing effects, adverse events (AEs), and safety issues associated with inhaled analgetic agents compared with other prehospital analgesic agents. As part of an initiative from the Scandinavian Society of Anaesthesia and Intensive Care Medicine, we conducted a systematic review (PROSPERO CRD42018114399), applying the PRISMA guidelines, Grading of Recommendations Assessment, Development, and Evaluation (GRADE), and Cochrane methods, searching the Cochrane Library, Epistemonikos, Centre for Reviews and Dissemination, PubMed, and EMBASE databases (updated March 2024). Inclusion criteria were the use of inhaled analgesic agents in adult patients with acute pain in the prehospital emergency care setting. All steps were performed by minimum of two individual researchers. The primary outcome was pain reduction; secondary outcomes were speed of onset, duration of effect, and relevant AEs. We included seven studies (56,535 patients in total) that compared inhaled agents (methoxyflurane [MF] and nitrous oxide [N2O]) to other drugs or placebo. Study designs were randomized controlled trial (1; n = 60), randomized non-blinded study (1; n = 343), and randomized open-label study (1; n = 270). The remaining were prospective or retrospective observational studies. The evidence according to GRADE was of low or very low quality. No combined meta-analysis was possible. N2O may reduce pain compared to placebo, but not compared to intravenous (IV) paracetamol, and may be less effective compared to morphine and MF. MF may reduce pain compared to paracetamol, ketoprofen, tramadol, and fentanyl. Both agents may be associated with marked but primarily mild AEs. We found low-quality evidence suggesting that both MF and N2O are safe and may have a role in the management of pain in the prehospital setting. There is low-quality evidence to support MF as a short-acting single analgesic or as a bridge to IV access and the administration of other analgesics. There may be occupational health issues regarding the prehospital use of N2O.

Behind the scenes: a qualitative study on threats and violence in emergency medical services

The increasing prevalence of threats and violence against ambulance clinicians is a critical issue that has not been adequately studied. These incidents pose significant challenges to the provision of prehospital emergency care, affecting both the safety and well-being of the clinicians involved. This study aimed to explore the experiences of Swedish ambulance clinicians when encountering threats and violence during their work. A qualitative approach was used, involving semi-structured interviews with 11 ambulance clinicians from various regions of Sweden. The participants were selected to ensure diversity in gender, age, and educational background. The data were collected over three weeks in 2021 and analyzed using qualitative content analysis. The analysis revealed three key categories related to the challenges faced by ambulance clinicians: Police cooperation challenges, Strategies for a safe care environment, and Impact during and relief after stressful events. These categories highlight the complexities of managing threats and violence in the field. This study sheds light on the multifaceted challenges that ambulance clinicians face due to threats and violence. It underscores the urgent need for comprehensive training, effective communication, and clear role allocation in complex situations. Furthermore, it emphasizes the importance of organized support systems to help clinicians cope with the aftermath of stressful events.

Professionalizing Emergency Medical Service Response Time

Abstract Prompt responses by emergency medical services (EMSs) are crucial in delivering efficient prehospital emergency treatment. The prompt arrival of EMS is strongly correlated with improved patient outcomes and increased chances of survival. To reduce the occurrence of long-term impairment or illness, the majority of EMS companies follow globally acknowledged response time benchmarks. Internationally, EMSs strive to achieve a response time of 8 min or less for 90% of life-threatening incidents. This research examines many variables that influence EMS response times and their subsequent consequences on patient outcomes. The measurement of response time starts with receipt of a clinical complaint call and concludes upon the arrival of EMS at the site. Timely and effective reactions are essential for the survival of patients, particularly in urgent medical situations. In contrast, there are data indicating that longer reaction times are associated with increased death rates. Various obstacles might hinder prompt EMS responses, including geographical obstacles, unfavorable weather and traffic conditions, and patient-specific considerations such as the kind of injury or sickness, medical history, age, and gender. In addition, a lack of staff, including insufficient workers, poor training, and the absence of standardized, up-to-date technology that simplify care delivery, may also cause delays in response times. Due to the crucial importance of EMS response times in prehospital emergency treatment, it is essential for EMS systems to make every effort to meet their response time goals.

Exploring Burnout, Work Addiction, and Stress-Related Growth among Prehospital Emergency Personnel.

Burnout and stress-related issues are significant concerns among medical personnel involved in emergency situations due to the high demands of their work. A cross-sectional descriptive and comparative study was conducted on 266 prehospital emergency personnel across five Romanian counties, comprising 41 physicians, 74 nurses, and 151 paramedics. Data were collected through an online form, including demographic and professional characteristics, and five validated scales. This study revealed moderate (49.3%) to high (25.9%) burnout rates, with 35% showing signs of work addiction. Despite these challenges, the personnel demonstrated high levels of stress-related growth (61.2%), strong self-discipline (74.1%), and low to moderate responsive distress (100%). Physicians exhibited higher work addiction and job satisfaction, whereas paramedics faced higher burnout, self-discipline, and distress levels. Nurses showed lower burnout and self-discipline levels. These findings highlight the prevalence of burnout and work addiction among emergency medical personnel, while also underscoring the presence of protective factors like higher self-discipline, good level of stress-related growth, and low to moderate responsive distress. The distinct differences in experiences among physicians, nurses, and paramedics emphasize the need for tailored strategies to address these issues within each group.

Development of the National Prehospital Pediatric Readiness Project assessment

AbstractIntroductionIn the United States (US), the quality of care provided to children during emergencies is highly variable. Following implementation of the National Pediatric Readiness Project (NPRP), inclusive of two national online assessments of Emergency Departments (EDs), national organizations involved in Emergency Medical Services (EMS) systems convened to launch the Prehospital Pediatric Readiness Project (PPRP). The PPRP seeks to ensure high‐quality pediatric prehospital emergency care for all children. One of the first priorities of PPRP is to assess the current level of pediatric readiness in EMS systems. The development of the first comprehensive national assessment of pediatric readiness in EMS systems is described.MethodsThe 2020 joint policy statement, “Pediatric Readiness in Emergency Medical Services Systems” and the associated prehospital pediatric readiness checklist served as the foundation for the PPRP assessment. Assessment questions and scoring algorithm were developed using a modified Delphi process. The PPRP Assessment was converted into an online format comprising a website (EMSpedsReady.org), the online assessment, a personalized gap report, and non‐public Tableau data‐monitoring dashboards. A directory of all eligible EMS agencies in the United Staters was created to track participation. A diverse cohort of 15 EMS agencies piloted of the assessment questions and the online version of the assessment. Feedback from the pilot was integrated.ConclusionThe inaugural PPRP Assessment was open access May through July 2024, and the results will be used to guide future PPRP efforts.

Expectations of healthcare professionals of community-based telemedicine in emergency medical service

Background In times of demographic change and an immense shortage of qualified personnel in emergency medical services, telemedicine could offer more efficient solutions for better care. Given the community-based nature of emergency services, local communities play an important role. This study explored the expectations of healthcare professionals and volunteers for telemedicine tools in prehospital emergency medicine. Methods This mixed-methods study was conducted in the rural region of Burgenland in Austria with stakeholders of the local emergency medical service in two focus groups (13 participants) and 99 quantitative questionnaires. Results Combining quantitative and qualitative data, we found that a majority of respondents (almost 80%) already experienced basic telemedicine and consider it valuable. In particular, there is a strong expectation for diagnostic support and inquiries related to potential hospitalization. Findings from two focus groups emphasized the importance of cultivating an improved learning culture, developing a specific mindset, and refining soft skills. The optimal telemedicine solution includes a knowledgeable and experienced tele-emergency physician coupled with user-friendly technology. Conclusion To be clear about the expectations of stakeholders, it is essential to involve all stakeholders right from the beginning. The solution should prioritize the integration of existing structures and be seamlessly incorporated into an evolving learning culture, while also fostering the necessary mindsets alongside educational aspects.

Design of a Mixed-Reality Application to Reduce Pediatric Medication Errors in Prehospital Emergency Care

Children in prehospital emergency care are particularly vulnerable to medication errors, often with serious consequences. A prior study analyzing prehospital pediatric medication dosing errors, conducted after the implementation of a statewide pediatric drug-dosing reference for emergency medical services (EMS), identified an alarmingly high error rate. This significant finding led to the current study, which aims to develop technological interventions to reduce the frequency of medication errors for children during treatment by EMS. The current study focuses on the design and development of a safety strategy to automate medication administration using mixed-reality technology. Simulations were conducted to inform the design process, focusing on three scenarios: cardiac arrest, seizure, and burns. The design team included medical and engineering researchers, paramedics, and emergency medical technicians from multiple emergency medical service agencies. Root cause analysis (RCA) and failure mode and effects analysis (FMEA) were conducted after the simulations were completed. The RCA and FMEA were used to identify and prioritize failure points, which were then addressed in a mixed-reality solution using Microsoft HoloLens 2 to automate and enhance pediatric medication administration in prehospital emergency care. The resulting application will provide real-time assistance to guide paramedics through the complicated medication dosing and administration process using a detailed step-by-step guide, aiming to decrease medication errors and improve medication dosing accuracy.

Knowledge, Attitudes and Practices of Radiologists and Paramedics Towards Accident and Emergency Preparedness and the Role of Biomedical Engineering in Prehospital Emergencies

Purpose: The purposes of this study were to assess the knowledge, attitude, and practice of radiologists and paramedics regarding accident and emergency preparedness in hospitals in the southern region of the Kingdom of Saudi Arabia and how to improve their role. Materials and methods: This was a descriptive, cross‑sectional online survey that was carried out among radiologists and paramedics in the Kingdom of Saudi Arabia. A self-structured, close-ended questionnaire that was administered that consisted of 19 questions was included. The questionnaire validity and reliability were evaluated for vetting and remarks. The questions were circulated through Google Forms, and it was circulated among the study participants through online mode. The data were collected systematically, and SPSS Statistics version 26.0 was used for data analysis Results: There were 139 responses, (77 specialist's radiology and 62 paramedics) participated in the study through Google Forms. In the study group, 84 (61.4%) were know the main steps for emergency response in major emergencies (p-value 0.000). Among the 19 questions used to assess the KAP, 12 questions were significant with a p-value less than 0.05. More than 72.6% agree the Management must be adequately prepared when emergencies and accidents occur. The respondents’ attitude toward emergency preparedness was generally positiveو Only a minority, that is, 43 (30.9%) of the respondents think it is possible for cooperation between radiologists and paramedics to interpret emergency cases and develop treatment plans in the emergency department. Conclusion: The level of knowledge was satisfactory among the radiologists and paramedics with a neutral level of attitudes, practice and knowledge regarding disaster preparedness. Follow-up research is essential to maximize the preparedness of the accident and emergency department.

Hybrid emergency care at the home for patients – A multiple case study

IntroductionHealthcare systems worldwide are facing numerous challenges, such as an aging population, reduced availability of hospital beds, staff reductions and closure of emergency departments (ED). These issues can exacerbate crowding and boarding problems in the ED, negatively impacting patient safety and the work environment. In Sweden a hybrid of prehospital and intrahospital emergency care has been established, referred to in this article as Medical Emergency Team (MET), to meet the increasing demand for emergency care. MET, consisting of physicians and nurses, moving emergency care from EDs to patients’ home. Physicians and nurses may encounter challenges in their healthcare work, such as limited resources for example medical equipment, sampling and examination, in unfamiliar varying home environments. There is a lack of knowledge about how these challenges can influence patient care. Therefore, the aim of this study was to explore the healthcare work of the METs when addressing patients’ emergency care needs in their homes, with a focus on the METs reasoning and actions.MethodsUsing a qualitative multiple case study design, two METs in southwestern Sweden were explored. Data were collected from September 2023 – January 2024 and consist of field notes from participant observations, short interviews and written reflections. A qualitative manifest content analysis with an inductive approach was used as the analysis method.ResultThe result of this study indicates that physicians and nurses face several challenges in their daily work, such as recurring interruptions, miscommunication and faltering teamwork. Some of these problems may arise because physicians and nurses are not accustomed to working together as a team in a different care context. These challenges can lead to stress, which ultimately can expose patients to unnecessary risks.ConclusionWhen launching a new service like METs, which is a hybrid of prehospital and intrahospital emergency care, it is essential to plan and prepare thoroughly to effectively address the challenges and obstacles that may arise. One way to prepare is through team training. Team training can help reduce hierarchical structures by enabling physicians and nurses to feel that they can contribute, collaborate, and take responsibility, leading to a more dynamic and efficient work environment.

Ventricular arrhythmias in acute heart failure: a clinical consensus statement of the Association for Acute CardioVascular Care, the European Heart Rhythm Association, and the Heart Failure Association of the European Society of Cardiology.

Patients presenting with or alerting emergency networks due to acute heart failure (AHF) form a diverse group with a plethora of symptoms, risks, comorbidities, and aetiologies. During AHF, there is an increased risk of destabilizing the functional substrate and modulatory adding to the risk of ventricular arrhythmias (VAs) already created by the structural substrate. New VAs during AHF have previously identified patients with higher intra-hospital and 60-day morbidity and mortality. Risk stratification and criteria/best time point for coronary intervention and implantable cardioverter defibrillator implantation, however, are still controversial topics in this difficult clinical setting. The characteristics and logistics of pre-hospital emergency medicine, as well as the density of centres capable of treating AHF and VAs, differ massively throughout Europe. Scientific guidelines provide clear recommendations for the management of arrhythmias in patients with chronic heart failure. However, the incidence, significance, and management of arrhythmias in patients with AHF have been less studied. This consensus paper aimed to address the identification and treatment of VAs that complicate the course of patients who have AHF, including cardiogenic shock.

Workshop-based training of pre-hospital emergency technicians for acute psychiatric patients: benefits and drawbacks

BackgroundPre-hospital emergency technicians are crucial in managing patients with acute psychiatric symptoms. They must quickly assess the condition, make a primary diagnosis, and refer the patient to the appropriate treatment center. Insufficient skills in these situations can cause serious harm. Educating technicians on dealing with these patients may enhance their knowledge and skills; however, we do not know the extent and longevity of this improvement and which areas are affected. This study investigates the impact of training on pre-hospital emergency technicians’ knowledge and skills.MethodsThis quasi-experimental study involved pre-hospital emergency technicians in Robat Karim and Nasim Shahr counties from December 2022 to January 2022. The technicians received workshops on interacting with psychiatric patients. The training topics included the basic principles of coping with a psychiatric patient. They also covered a step-by-step approach to dealing with an aggressive patient, dealing with a patient threatening suicide, managing agitation, managing a patient suffering from panic attacks, and finally dealing with a delirious patient. A pre-test assessed their baseline knowledge and skills, followed by a post-test after training and another test three months later. The test results were analyzed.ResultsThis study involved forty male participants ranging in age from 25 to 44 and with work experience ranging from five to twenty years. As a result of training in dealing with acute psychiatric patients, technicians developed significant skills and knowledge immediately after training, and these improvements remained significant three months after training. Nevertheless, the correct answers decreased during the three-month follow-up compared to the pre-test. Education was less effective at managing panic, delirium, and agitation.ConclusionIn conclusion, technicians’ knowledge and skills can be effectively enhanced through training; however, the impact diminishes with time. Theories and practical methods, periodic repetition, and real-world internships are the best ways to maximize training effectiveness.

Prehospital neurological emergencies– a survey on the state of prehospital neurological assessment by emergency medical professionals

BackgroundNeurological emergencies are one of the major diagnosis groups in the Emergency Medical Services (EMS) with the highest rate of misdiagnosis. Despite the knowledge of time sensitivity and the importance of prehospital factors, prehospital delay is common. Although several stroke triage scales have been developed, a gold standard in the prehospital setting is lacking.ObjectivesOur aim was to evaluate the perception of neurological emergencies by EMS personnel and to identify current problems, difficulties and opportunities for improvement in the prehospital management of stroke, seizure, non-specific neurological symptoms, and paediatric neurological emergencies.MethodsThe study was conducted as an online survey through SoSci Survey and was made available from March 1st to June 30th 2023 to all personnel working in emergency medical services. The access link was distributed through snowballing, social media, and through a QR code on a promotional poster. The survey was completed anonymously. The final survey consisted of 30 questions in German on the topics of neurological emergencies, general neurological assessment, specific neurological examination including paediatric assessment, stroke, and seizures, and finally suggestions for improvement.ResultsThe largest group of participants were paramedics, who estimated to encounter neurological emergencies at a general rate of 20–60%. When unease was felt, the main reasons were ambiguity of symptoms and insufficient admission capacity of hospitals. The biggest challenges were highly varied. Almost 80% of participants assumed that the neurological assessment would be omitted in difficult patient groups such as demented, intoxicated or children. 75% felt uncomfortable making a paediatric assessment, 50% were unfamiliar with the Paediatric Glasgow Coma Scale.ConclusionsSupport through more standardized practical training and defined, uniform guidelines is needed. There was also a clear need for peer collaboration, feedback and case sharing. Digitalization, the usage of telemedicine and updated versions of the documentation protocols including paediatric adaptations to current guidelines could further improve current neurological assessment in the prehospital setting.

Improving Triage Accuracy in Prehospital Emergency Telemedicine: Scoping Review of Machine Learning-Enhanced Approaches.

Prehospital telemedicine triage systems combined with machine learning (ML) methods have the potential to improve triage accuracy and safely redirect low-acuity patients from attending the emergency department. However, research in prehospital settings is limited but needed; emergency department overcrowding and adverse patient outcomes are increasingly common. In this scoping review, we sought to characterize the existing methods for ML-enhanced telemedicine emergency triage. In order to support future research, we aimed to delineate what data sources, predictors, labels, ML models, and performance metrics were used, and in which telemedicine triage systems these methods were applied. A scoping review was conducted, querying multiple databases (MEDLINE, PubMed, Scopus, and IEEE Xplore) through February 24, 2023, to identify potential ML-enhanced methods, and for those eligible, relevant study characteristics were extracted, including prehospital triage setting, types of predictors, ground truth labeling method, ML models used, and performance metrics. Inclusion criteria were restricted to the triage of emergency telemedicine services using ML methods on an undifferentiated (disease nonspecific) population. Only primary research studies in English were considered. Furthermore, only those studies using data collected remotely (as opposed to derived from physical assessments) were included. In order to limit bias, we exclusively included articles identified through our predefined search criteria and had 3 researchers (DR, JS, and KS) independently screen the resulting studies. We conducted a narrative synthesis of findings to establish a knowledge base in this domain and identify potential gaps to be addressed in forthcoming ML-enhanced methods. A total of 165 unique records were screened for eligibility and 15 were included in the review. Most studies applied ML methods during emergency medical dispatch (7/15, 47%) or used chatbot applications (5/15, 33%). Patient demographics and health status variables were the most common predictors, with a notable absence of social variables. Frequently used ML models included support vector machines and tree-based methods. ML-enhanced models typically outperformed conventional triage algorithms, and we found a wide range of methods used to establish ground truth labels. This scoping review observed heterogeneity in dataset size, predictors, clinical setting (triage process), and reported performance metrics. Standard structured predictors, including age, sex, and comorbidities, across articles suggest the importance of these inputs; however, there was a notable absence of other potentially useful data, including medications, social variables, and health system exposure. Ground truth labeling practices should be reported in a standard fashion as the true model performance hinges on these labels. This review calls for future work to form a standardized framework, thereby supporting consistent reporting and performance comparisons across ML-enhanced prehospital triage systems.
