Education and training of prehospital first responders in low- and middle-income countries

Prehospital emergency medical services play a vital role in providing essential emergency medical and trauma care. However, in many low- and middle-income countries, there is a significant lack of adequate emergency medical services coverage, a problem compounded by a profound deficit of first responder training programs. The African Federation of Emergency Medicine classifies prehospital emergency care into 2 categories: tier-1, which includes laypersons, and tier-2, consisting of professionals equipped with dispatch capabilities. Both tier-1 and tier-2 first responders require protocolized training, integration, and coordination to varying degrees, with tier-1 programs focusing primarily on immediate stabilization and hospital transportation and tier-2 programs dedicating increased focus toward formal dispatch and advanced life support interventions. Training for both tiers of emergency medical services typically involves in-person didactic lectures with practical skills sessions. However, the content of these courses is highly context-dependent, and there is no international consensus regarding pedagogical methods or curriculum content for first responder training in low- and middle-income countries.Similarly, there is a lack of consensus in monitoring and evaluating training programs, including assessment methods, passing scores, and certification requirements. Although many programs use knowledge or skills acquisition testing, the content and depth of these examinations vary greatly, and long-term follow-up reporting is limited. As such, the educational landscape of both tier-1 and tier-2 emergency medical services in low- and middle-income countries remains highly varied and often faces a dual challenge of lacking clear international guidelines while still maintaining local appropriateness. Modular curricula developed in conjunction with standardized needs assessments, accompanied by the adoption of the training of trainers model, may present a pathway for local adaptability by leveraging local community members to inform and proliferate training. Although there have been notable improvements in prehospital training programs in resource-limited settings during the past 3 decades, challenges related to maintaining fidelity in monitoring and evaluation, expanding programs within resource constraints, and adapting to specific contexts continue to offer opportunities for further development in the future.

Evaluation of Prehospital Undertriage in Relation to Trauma Team Activation-Results from a Prospective Study in 12 Level one German Trauma Centers.

Background/Objective: This prospective, multicenter observational cohort study was carried out in 12 trauma centers in Germany and Switzerland. Its purpose was to evaluate the rate of undertriage, as well as potential consequences, and relate these with different Trauma Team Activation Protocols (TTA-Protocols), as this has not been done before in Germany. Methods: Each trauma center collected the data during a three-month period between December 2019 and February 2021. All 12 participating hospitals are certified as supra-regional trauma centers. Here, we report a subgroup analysis of undertriaged patients. Those included in the study were all consecutive adult patients (age ≥ 18 years) with acute trauma admitted to the emergency department of one of the participating hospitals by the prehospital emergency medical service (EMS) within 6 h after trauma. The data contained information on age, sex, trauma mechanism, pre- and in-hospital physiology, emergency interventions, emergency surgical interventions, intensive care unit (ICU) stay, and death within 48 h. Trauma team activation (TTA) was initiated by the emergency medical services. This should follow the national guidelines for severe trauma using established field triage criteria. We used various denominators, such as ISS, and criteria for the appropriateness of TTA to evaluate the undertriage in four groups. Results: This study included a total of 3754 patients. The average injury severity score was 5.1 points, and 7.0% of cases (n = 261) presented with an injury severity score (ISS) of 16+. TTA was initiated for a total of 974 (26%) patients. In group 1, we evaluated how successful the actual practice in the EMS was in identifying patients with ISS 16+. The undertriage rate was 15.3%, but mortality was lower in the undertriage cohort compared to those with a TTA (5% vs. 10%). In group 2, we evaluated the actual practice of EMS in terms of identifying patients meeting the appropriateness of TTA criteria; this showed a higher undertriage rate of 35.9%, but as seen in group 1, the mortality was lower (5.9% vs. 3.3%). In group 3, we showed that, if the EMS were to strictly follow guideline criteria, the rate of undertriage would be even higher (26.2%) regarding ISS 16+. Using the appropriateness of TTA criteria to define the gold standard for TTA (group 4), 764 cases (20.4%) fulfilled at least one condition for retrospective definition of TTA requirement. Conclusions: Regarding ISS 16+, the rate of undertriage in actual practice was 15.3%, but those patients did not have a higher mortality.

Prehospital and In-Hospital Treatment with Adrenaline and Related Prognosis in Anaphylaxis Patients

Introduction: Although intramuscular adrenaline is the recommended first-line treatment for anaphylaxis, not all patients receive this treatment. The consequences in daily clinical practice are sparsely described. This study aimed to investigate the treatment administered to anaphylactic patients and the related prognosis. Methods: A retrospective register-based study of patients with anaphylaxis referred to the allergy centre, Odense University Hospital (2019–2021). Each patient’s medical records were reviewed for contacts with the emergency departments and the prehospital emergency medical service in the Region of Southern Denmark. The World Allergy Organization (WAO) grading system was used to assess the severity of prehospital and in-hospital anaphylaxis. Furthermore, the treatment administered to the patients was registered. Results: In total, 315 patients were included. The prehospital system had contact with 256 of these patients (two were released prehospitally following treatment and 12 patients had insufficient data to assess anaphylaxis). Of the remaining 242 patients, 115 had anaphylaxis prehospitally (WAO grades 3–5); 59% (67/115) received adrenaline. Among the 67 patients who received prehospital adrenaline, 9 patients (13.4%; 95% CI: 6.3–24.0%) still had anaphylaxis at arrival at the emergency department. Of the 48 patients that were not treated with prehospital adrenaline, 17 patients (35.5%; 95% CI: 22.1–50.5) had anaphylaxis at the arrival to the emergency department. Among the 127 patients without prehospital anaphylaxis (WAO grades 0–2), 22 patients (18.2%; 95% CI: 11.8–26.2%) who did not receive prehospital adrenaline had anaphylaxis at arrival to the emergency department, while none of the 6 patients treated prehospitally with adrenaline had anaphylaxis. Conclusion: Omission of prehospital adrenaline in anaphylactic patients is associated with more severe anaphylactic symptoms at arrival to the hospital. Adrenaline treatment remains suboptimal since only half of the patients received prehospital adrenaline and only 1 out of 4 patients, with clinical signs of anaphylaxis, received adrenaline inside the hospital.

Use of bitemporal NACA score documentation in prehospital emergency medical services– a retrospective study

BackgroundThe assessment of illness severity in the prehospital setting is essential for guiding appropriate medical interventions. The National Advisory Committee for Aeronautics (NACA) score is a validated tool commonly used for this purpose. However, the potential benefits of using bitemporal documentation of NACA scores to capture the dynamic changes in emergency situations remain uncertain. The objective of this study was to evaluate the potential benefit of bitemporal NACA score documentation in the prehospital setting, specifically in assessing the dynamic changes of emergencies and facilitating quality improvement through enhanced documentation practices.MethodsIn this retrospective study, data from prehospital emergency patients were analyzed who received care from the physician response unit between January 1, 2018, and May 31, 2021. Patient demographics, NACA scores, indications for emergency care, and changes in NACA scores were extracted from medical records. Statistical analyses were performed to examine the associations between NACA scores, emergency categories, indications, and changes in NACA scores.ResultsThe study included 4005 patients, predominantly categorized as NACA III (33.7% at initial assessment, 41.8% at subsequent assessment) and NACA IV (31.6% at initial assessment, 22.4% at subsequent assessment). There was a significant improvement in NACA scores during the provision of prehospital care (p < 0.01). Notably, prehospital emergencies attributed to internal medical, neurological, traumatic, and paediatric causes demonstrated significant improvements in NACA scores (p < 0.01). Gender-specific differences were also observed.ConclusionOur study suggests that the bitemporal documentation of NACA scores can be advantageous in the prehospital setting and may have implications for research, practice, and policy.

Ketorolac vs. Fentanyl: A retrospective chart review of analgesia in the prehospital environment

BackgroundWith growing concerns on the worsening opioid epidemic and provider hesitation for opioid use, opioid-sparing treatment regimens are being introduced such as ketorolac administration. The primary aims of this study are to compare the safety and efficacy of ketorolac to fentanyl in the prehospital setting and to determine ketorolac's potential as a practical alternative analgesic. MethodsA retrospective chart review of patient encounters obtained from a prehospital emergency medical services agency in New Mexico was conducted to evaluate the safety and efficacy of ketorolac vs. fentanyl in the prehospital setting. Primary outcomes assessed were the reported medication complications, initial pain, last pain, and pain reduction on a Numerical Rating Scale. Data was evaluated using unadjusted and adjusted (age, gender, and weight of the patient) models. ResultsA total of 4102 records were evaluated (3182 fentanyl cases vs. 920 ketorolac cases). No significant differences in initial, last pain or pain reduction were seen in unadjusted models and for age, gender, or weight adjusted models. However, adjusted models displayed a difference in the number of complications that occurred while all cases of medication complications occurred within the fentanyl group (64 occurrences, P<0.0001). Among the complications seen, nausea and hypoxia are the most frequent with 40.6 and 29.7% of occurrences respectively). ConclusionFindings suggest that ketorolac is both effective and safe in the prehospital environment when compared to fentanyl. These findings encourage prehospital agencies to adopt opioid-sparing treatment protocols to encourage increased treatment of pain without potentiating the current opioid epidemic.

Associations between paramedics' salutogenic health experience and the intention to stay in the profession: A cross-sectional survey.

To investigate the association between paramedics' salutogenic health and their intentions to stay in their profession. A cross-sectional survey. Paramedics from eight purposively selected organizations participated in this study (n = 433). The data were collected in 2022 with the Salutogenic Health Indicator Scale and validated single questions that assessed work ability, recovery and self-rated stress. Intention to stay was measured using two questions about the intention to leave prehospital emergency medical service work and leave the nursing sector completely during the next 2 years. Data were analysed using logistic regression and statistical significance tests. Men had higher mean salutogenic health scores than women. No significant differences in salutogenic health were observed across work experience or occupational groups. Paramedics intending to stay in their profession exhibited higher salutogenic health scores than those intending to leave. In the logistic regression models, increasing levels of salutogenic health and work ability were associated with intention to stay in the profession.

Long-term effects of a prehospital telemedicine system on structural and process quality indicators of an emergency medical service

The benefits of a telemedical support system for prehospital emergency medical services include high-level emergency medical support at the push of a button: delegation of drug administration, diagnostic assistance, initiation of therapeutic measures, or choice of hospital destination. At various European EMS sites telemedical routine systems are shortly before implementation. The aim of this study was to investigate the long-term effects of implementing a tele-EMS system on the structural and procedural quality indicators and therefore performance of an entire EMS system. This retrospective study included all EMS missions in Aachen city between 2015 and 2021. Regarding structural indicators of the EMS system, we investigated the overall number of emergency missions with tele-EMS and onsite EMS physicians. Furthermore, we analyzed the distribution of tracer diagnosis and process quality with respect to the time spans on the scene, time until teleconsultation, duration of teleconsultation, prehospital engagement time, and number of simultaneous teleconsultations. During the 7-year study period, 229,384 EMS missions were completed. From 2015 to 2021, the total number of EMS missions increased by 8.5%. A tele-EMS physician was consulted on 23,172 (10.1%) missions. The proportion of telemedicine missions increased from 8.6% in 2015 to 12.9% in 2021. Teleconsultations for missions with tracer diagnoses decreased during from 43.7% to 30.7%, and the proportion of non-tracer diagnoses increased from 56.3% to 69.3%. The call duration for teleconsultation decreased from 12.07 min in 2015 to 9.42 min in 2021. For every fourth mission, one or more simultaneous teleconsultations were conducted by the tele-EMS physician on duty. The implementation and routine use of a tele-EMS system increased the availability of onsite EMS physicians and enabled immediate onsite support for paramedics. Parallel teleconsultations, reduction in call duration, and increase in ambulatory onsite treatments over the years demonstrate the increasing experience of paramedics and tele-EMS physicians with the system in place. A prehospital tele-EMS system is important for mitigating the current challenges in the prehospital emergency care sector.

The Impact of the COVID-19 Pandemic on Pre-Hospital Emergency Medical Services: The impact of the Covid-19 pandemic on pre-hospital services.

The novel coronavirus (COVID-19) disease outbreak started in China and went on to affect the entire world. Healthcare providers were among the communities that faced severe challenges during the pandemic, and this was especially true of Pre-Hospital Emergency Medical Services (PHEMS) providers. This study aims to investigate the effect of the COVID-19 pandemic on service requests submitted to PHEMS providers via calls made to emergency hotlines. Data were obtained on calls made to 112 (the emergency hotline) during March - August 2020 (i.e., during the pandemic) and the same period the previous year (i.e., the pre-pandemic period). These 2 data sets were analyzed and compared using the SPSS 26 software package (IBM Corp., Armonk, New York, USA). The results of the analysis indicated that the total number of emergency calls received during the pandemic period (11 745) increased compared to the pre-pandemic period (10 747), whereas there was a decrease in the proportion of trauma-related emergency calls during the pandemic period (5.3%) compared to the pre-pandemic period (6.8%). Furthermore, there was a higher proportion of extended service times among ambulances serving in PHEMS during the pandemic period (ambulance movements longer than 90 seconds: 15.6%) compared to the pre-pandemic period (ambulance movements longer than 90 seconds: 8.6%). Non-emergency ambulance usage rate was 44.90% in the pre-pandemic period and 38.90% in the pandemic period. As the study's results show that there was an increase in the number of calls to PHEMS during the pandemic period, especially given that a significant portion of these calls consisted of non-emergency calls, it is recommended that measures be taken to reduce the excessive load on PHEMS during a pandemic.

Emergency Medical Service in the Elderly Population in Iran: A Cross-sectional Study Before and During the COVID-19 Pandemic.

This research examines the impact of an aging population in Eastern Iran on prehospital emergency medical services (EMS), with a focus on changes before and during the COVID-19 pandemic. A descriptive cross-sectional analysis was performed on data from 10,264 elderly individuals using EMS in Torbat-e Heydarieh County from March 2019 to March 2022. Statistical analyses, including t-tests and Chi-square tests, were conducted using SPSS software. Findings indicate that 30% of the 33,847 EMS calls received were from older adults. The nature of emergencies evolved from cardiovascular issues pre-pandemic to predominantly impaired consciousness during COVID-19, a statistically significant shift (p < .001). The study concludes with a call for research targeted at this demographic and suggests setting up dedicated EMS response units to cater to the elderly, responding to the increase in elderly-related EMS needs.

Approaches for Enhancing Pre-hospital EMS Response during the COVID-19 Pandemic Machine Learning

Background: Coronavirus disease 2019 (COVID-19) caused an unprecedented healthcare crisis and warranted a need to use artificial intelligence (AI) and machine learning (ML) for enhancing caller screening and triage within pre-hospital Emergency Medical Services (EMS) specifically tailored to COVID-19 cases. This study aimed to analyze existing AI and ML models and assess their accuracy and precision. Methods: A comprehensive assessment of artificial intelligence (AI) applications used to improve EMS responses in the context of COVID-19 instances was done. The dataset produced by Mexican government was used. This dataset was assessed over different models encompassing logistic regression, random forest, gradient boosting, neural networks, k-nearest neighbors (KNN), Naive Bayes, and clustering (K-means). Results: Multiple models performance evaluation was done employing metrics such as accuracy, precision, recall, and F1-score to comprehensively assess the strengths and limitations of these models. Conclusion: The study\&amp;apos;s findings underline the complexities inherent in caller screening and triage for COVID-19 cases, showcasing diverse strengths and limitations within the deployed machine learning models. The discourse underscores the necessity for a multifaceted approach to effectively manage the intricate challenges associated with caller classification and triage, offering invaluable insights for future research endeavors and guiding the enhancement of emergency healthcare systems.

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.

Learning Lessons for Future Preparedness: Exploring Work Well-Being-Related Leadership Challenges among Paramedics during the Early Stage of the COVID-19 Pandemic-A Qualitative Study.

The beginning of the COVID-19 pandemic majorly impacted the population and public services. In Finland, a state of emergency was declared to ensure the security of healthcare resources, and prehospital emergency medical service (EMS) organizations faced emergency conditions for the first time. This study explores the leadership challenges related to well-being experienced during the early phase of the pandemic. This qualitative study utilized reflective essay material written between August and November 2020 by experienced advanced-level paramedics (n = 30) who participated actively in EMS fieldwork at the beginning of the pandemic. The material (32,621 words) was analyzed with inductive content analysis. The work well-being-related leadership challenges experienced by paramedics during the early phase of the pandemic were divided into four upper categories: inadequate guidance, workplace reorganization, atmosphere mismanagement, and insufficient resources to cope. These upper categories were comprised of 17 subcategories. Several actions can be taken to enhance personnel well-being and prepare for similar challenges. Guidance and support should be clear and timely. Visible leadership should be emphasized and enhanced with modern communication. Efforts should be made to strengthen the work atmosphere to support those on the front lines of healthcare. This study was not registered on a publicly accessible registry.

Use of Stroke Alert Sticker in the Field Decreases Time to Acute Interventions for Ischemic Stroke Patients.

BACKGROUND: Stroke is a medical emergency requiring timely intervention to optimize patient outcomes. The only treatments currently Food and Drug Administration approved for acute stroke are intravenous (IV) thrombolytics, which require obtaining specific medical history to be administered safely. This medical history may be overlooked in the prehospital setting or lost during patient handoff between emergency medical services (EMS) personnel and hospital staff, delaying treatment. We evaluated whether utilization of a "stroke alert sticker" by EMS to capture key information in the field would decrease door-to-needle (DTN) time. METHODS: Bright-orange "stroke alert stickers" were disseminated to our local EMS agency to be placed on all suspected stroke patients in the field prompting documentation of key elements needed for timely treatment decisions. The "stroke alert sticker" included time last known well, contact information, presenting symptoms, and relevant medications. We evaluated the impact of the "stroke alert sticker" on acute stroke metrics, including DTN time. RESULTS: The project included 220 consecutive stroke alert patients brought to our comprehensive stroke center by a single EMS agency from May 2021 through February 2022. Twenty-one patients were treated with an IV thrombolytic. Overall "stroke alert sticker" use compliance was 40%; for the subgroup of patients who were given an IV thrombolytic, the "stroke alert sticker" was used 60% of the time. In patients who received an IV thrombolytic, prehospital EMS notification was 100% with "stroke alert sticker" use, compared with 75% without (P = .13). In addition, with "stroke alert sticker" utilization, DTN time was reduced by 20 minutes (31 [11] minutes with sticker vs 51 [21] minutes without, P = .04). CONCLUSION: Utilization of the "stroke alert sticker" significantly improved DTN times compared with patients without the sticker. This evidence supports continued use of the "stroke alert sticker" to improve DTN times and patient outcomes.

Characteristics of pediatric behavioral health emergencies in the prehospital setting.

Approximately 10% of emergency medical services (EMS) encounters in the United States are behavioral health related, but pediatric behavioral health EMS encounters have not been well characterized. We sought to describe demographic, clinical, and EMS system characteristics of pediatric behavioral health EMS encounters across the United States and to evaluate factors associated with sedative medication administration and physical restraint use during these encounters. We conducted a retrospective cross-sectional study of pediatric (<18 years old) behavioral health EMS encounters from 2019 to 2020 using the National Emergency Medical Services Information System. Behavioral health encounters were defined using primary or secondary impression codes. We used multivariable logistic regression to identify factors associated with sedative medication administration and physical restraint use. Of 2,740,271 pediatric EMS encounters, 309,442 (11.3%) were for behavioral health. Of pediatric behavioral health EMS encounters, 85.2% of patients were 12-17 years old, 57.3% of patients were female, and 86.6% of encounters occurred in urban areas. Sedative medications and physical restraints were used in 2.2% and 3.0% of pediatric behavioral health EMS encounters, respectively. Sedative medication use was associated with the presence of developmental, communication, or physical disabilities relative to their absence (adjusted odds ratio [aOR] 3.38, 95% confidence interval [CI] 2.93-3.91) and with encounters in the West relative to the South (aOR 1.23, 95% CI 1.16-1.32). Physical restraint use was associated with encounters by patients 6-11 years old relative to those 12-17 years old (aOR 1.35, 95% CI 1.27-1.44), the West relative to the South (aOR 3.49, 95% CI 3.27-3.72), and private nonhospital EMS systems relative to fire departments (aOR 3.39, 95% CI 3.18-3.61). Among pediatric prehospital behavioral health EMS encounters, the use of sedative medications and physical restraint varies by demographic, clinical, and EMS system characteristics. Regional variation suggests opportunities may be available to standardize documentation and care practices during pediatric behavioral health EMS encounters.

Description of the prehospital emergency healthcare system in Norway

BackgroundNorway has a long coastline, steep mountains, and wide fjords, which presents some challenges to the prehospital emergency healthcare system. In recent years, the prehospital emergency medical services (EMS) have undergone significant changes, structurally, in terms of professionalisation of the services and in the education level of the personnel. In this article, we aim to describe the current structure for handling prehospital medical emergencies. MethodsFor healthcare, Norway is divided into four Regional Health Authorities, consisting of 19 Health Trusts, where 18 have an EMS. There is a dedicated medical emergency number, 113, that terminates in 16 emergency medical communication centres. The use of air and boat ambulances, in addition to traditional ambulances, seeks to meet the challenges in the EMS system. Strengths and limitationsThe Norwegian EMS is an advanced system with highly educated staff; however, this level of care comes with an equally high cost. ConclusionThe Norwegian EMS can handle emergencies nationwide, providing advanced care at the scene and during transport. The geography and demography challenge the idea of equal care, but the open publishing of data from national quality registries seeks to identify and address potential differences.

Relaxation and strain among emergency medical service personnel and emergency control center dispatchers during the first two waves of the SARS-CoV-2 pandemic.

Workloads of emergency medical service personnel (EMP) and emergency control center dispatchers (CCDs) were manifold. The SARS-CoV-2 pandemic presented new challenges for the prehospital emergency medical service. The purpose of this study was to compare the status of stress/strain and recovery of Recovery-Stress Questionnaire among EMP and CCDs in Germany during the first 2 waves of the SARS-CoV-2 pandemic both between occupational groups and over time. A total of 2426 emergency medical service personnel and control center dispatchers were questioned with the Recovery-Stress Questionnaire based on Kallus. The results from the first 2 waves of the pandemic (June-August 2020 and January-February 2021) were compared. During the first and second wave of SARS-CoV-2 pandemic, the subjectively perceived stress of emergency medical service personnel and control center dispatchers increased, but recovery decreased. The CCDs showed more unfavorable values compared to EMP. Health promotion interventions are necessary to counteract possible career changes or mental or other diseases due to insufficient management.

Telephone Assessment of Suicidal Risk at Prehospital Emergency Medical Services: A Direct Comparison with Face-to-Face Evaluation at Psychiatric Emergency Service

Objective Assessment of suicidal risk is one of the most challenging tasks faced by health professionals, notably in emergency care. We compared telephone suicide risk assessment at prehospital Emergency Medical Services Dispatch Center (EMS-DC), with subsequent face-to-face evaluation at Psychiatric Emergency Service (PES), using French national Risk-Urgency-Danger standards (RUD). Method Data were collected for all suicidal adult patients (N = 80) who were addressed by EMS-DC to PES between December 2018 and August 2019 and benefited from RUD assessment at both services. Suicidal risk was given a score of 1, 2, 3 or 4, in order of severity. Results Mean of the differences between the RUD score at EMS-DC and PES was −0.825 (SD = 1.19), and was found to be significant (p < 0.01). The average time between RUD assessments was 420 min (SD = 448) and was negatively correlated with the difference in the RUD score (r = −0.295, p = 0.008). Associated suicide attempt increased the odds of a decrease in the RUD score (OR = 2.989; 95% CI = 1.141–8.069; p < 0.05). Conclusions Telephone evaluation of suicidal risk using RUD at EMS-DC yielded moderately higher scores than those obtained by a subsequent face-to face evaluation at PES, with this difference partially explained by the time between assessments, and by clinical and contextual factors.

Effect of the COVID-19 pandemic on advanced life support units’ prehospital management of the stroke code in four Spanish regions: an observational study

IntroductionStroke is the most common time-dependent pathology that pre-hospital emergency medical services (EMS) are confronted with. Prioritisation of ambulance dispatch, initial actions and early pre-notification have a major impact on mortality and disability. The COVID-19 pandemic has led to disruptions in the operation of EMS due to the implementation of self-protection measures and increased demand for care. It is crucial to evaluate what has happened to draw the necessary conclusions and propose changes to improve the system’s strength for the future. The study aims to compare prehospital time and neuroprotective care metrics for acute stroke patients during the first wave of COVID-19 and the same periods in the years before and after.MethodsAnalytical, observational, multicentre study conducted in the autonomous communities of Andalusia, Catalonia, Galicia, and Madrid in the pre-COVID-19 (2019), “first wave” of COVID-19 (2020) and post-COVID-19 (2021) periods. Consecutive non-randomized sampling. Descriptive statistical analysis and hypothesis testing to compare the three time periods, with two by two post-hoc comparisons, and multivariate analysis.ResultsA total of 1,709 patients were analysed. During 2020 there was a significant increase in attendance time of 1.8 min compared to 2019, which was not recovered in 2021. The time of symptom onset was recorded in 82.8% of cases, and 83.3% of patients were referred to specialized stroke centres. Neuroprotective measures (airway, blood glucose, temperature, and blood pressure) were performed in 43.6% of patients.ConclusionDuring the first wave of COVID-19, the on-scene times of pre-hospital emergency teams increased while keeping the same levels of neuroprotection measures as in the previous and subsequent years. It shows the resilience of EMS under challenging circumstances such as those experienced during the pandemic.

Challenges and opportunities to improve efficiency and quality of prehospital emergency care using an mHealth platform: Qualitative study in Rwanda

IntroductionPrompt, high-quality pre-hospital emergency medical services (EMS) can significantly reduce morbidity and mortality. The goal of this study was to identify factors that compromise efficiency and quality of pre-hospital emergency care in Rwanda, and explore the opportunities for a mobile health (mHealth) tool to address these challenges. MethodsIn-depth interviews were conducted with 21 individuals representing four stakeholder groups: EMS dispatch staff, ambulance staff, hospital staff, and policymakers. A semi-structured interview guide explored participants’ perspectives on all aspects of the pre-hospital emergency care continuum, from receiving a call at dispatch to hospital handover. Participants were asked how the current system could be improved, and the potential utility of an mHealth tool to address existing challenges. Interviews were audio-recorded, and transcripts were thematically analyzed using NVivo. ResultsStakeholders identified factors that compromise the efficiency and quality of care across the prehospital emergency care continuum: triage at dispatch, dispatching the ambulance, locating the emergency, coordinating patient care at scene, preparing the receiving hospital, and patient handover to the hospital. They identified four areas where an mHealth tool could improve care: efficient location of the emergency, streamline communication for decision making, documentation with real-time communication, and routine data for quality improvement. While stakeholders identified advantages of an mHealth tool, they also mentioned challenges that would need to be addressed, namely: limited internet bandwidth, capacity to maintain and update software, and risks of data security breaches that could lead to stolen or lost data. ConclusionDespite the success of Rwanda's EMS system, this study highlights factors across the care continuum that could compromise quality and efficiency of prehospital emergency care. Mobile health tools hold great promise to address these challenges, but contextual issues need to be considered to ensure sustainability of use.
