Advanced-level paramedic perspectives on competence requirements for responding to radiological/nuclear incidents

The threat of chemical, biological, radiological, and nuclear (CBRN) incidents has been a topic of increasing concern in recent years, and the need for increasing preparedness and competence among the first responder professions is widely recognized. This qualitative study explored advanced-level paramedic perspectives on competence requirements for responding to radiological/nuclear (R/N) incidents. This study utilized reflective essays (n = 26) written by advanced-level paramedics after familiarizing themselves with a fictional accidental nuclear power plant incident scenario. The material was analyzed using inductive content analysis. Three main categories were found: 1) Awareness of operating in multi-authority RN incidents, 2) Consideration of occupational safety, and 3) Competence in emergency care nursing and management during RN incidents. The results can be utilized for enhancing the competence management and training provision of Emergency Medical Services organizations.

Creation and Establishment of the State Emergency Medical Services and Disaster Medicine Services in Russia (to the 100th Anniversary of the N.V. Sklifosovsky Research Institute for Emergency Medicine)

After the October Revolution of 1917, the creation of the state healthcare and medical education system in the country played a decisive role in the organization of emergency medical services (EMS) in Moscow on the basis of the former Sheremetev Hospital which later became a large multidisciplinary medical institution — N.V. Sklifosovsky Institute of Emergency Medicine (since 1943 — N.V. Sklifosovsky Research Institute for Emergency Medicine), — and the city EMS station as a part of it.In the pre-war period, the working out of the main principles for the EMS provision was critically important for the development of the services. It became possible to solve scientific and methodological problems related to the training of specialists. The Institute grew into a large institution, research in the field of emergency medicine was carried out at the world level. This contributed to the organization of a network of EMS institutions in the country during 1926–1935.The years of the Great Patriotic War of 1941–1945 enriched the practice of providing emergency medical care, including during mass patient admission.In the post-war years (1946–1970s), the Institute became the leading institution on the problems of EMS in the country. Corresponding divisions were created within the Institute, and on its basis — “Emergency Medicine” scientific and practical association, research and organizational structures of the USSR Ministry of Health, the RSFSR Ministry of Health and the USSR Academy of Medical Sciences. Thanks to this, outstanding results were achieved in the EMS organization: the specialty of “emergency medicine physician” was introduced; emergency hospitals were created in a number of the country’s regions; government programs for EMS provision were successfully implemented; а large number of regulatory documents were prepared to facilitate the further EMS development.N.V. Sklifosovsky Research Institute for Emergency Medicine was among the main initiators of the disaster medicine service, which made it possible to fundamentally solve its organizational and technical problems. Thus, a significant contribution was made to the foundation of this service in Moscow and around the country.At the current stage (from 1992 to the present), EMS improvement has been continued, many developments turned out to be relevant for this services in the Russian Federation. In particular, the created structure of the Institute’s admission and intensive care unit remained the flagship among emergency care institutions in the country for about 20 years. The state program “Improving medical care for road accident victims” was successfully implemented. The Institute’s departments are being actively specialized, making it possible to obtain fundamentally new scientific and practical results for widespread implementation.Since 2011, “Scientific achievements in the field of emergency medical care in the Russian Federation” - collections of research works - have been published annually. The information presented in them can be used throughout the country.The experience in treatment for the novel coronavirus infection COVID-19 allowed the Institute to begin a new page in the history of emergency medical services.The recent opening of an emergency inpatient complex at the Institute contributed to optimizing the work of the hospital’s resuscitation and intensive care units and expanding their treatment and diagnostic capabilities.For more than 10 years, the public and consolidating activities of the scientific and practical society of emergency medicine specialists have been effective. Its work primarily concerns the organization and conduct of scientific and practical events, especially congresses of emergency medicine physicians, as well as the publication of Sklifosovsky Journal Emergency Medical Care, which has unifying significance for a large number of Russian specialists in the field of EMS. The decisions made at the congresses and conferences became the basis for expanding the introduction of advanced medical technologies in the Russian regions, as well as for carrying out important structural reforms in EMS institutions.One of the main achievements of the N.V. Sklifosovsky Research Institute for Emergency Medicine is the creation of the state EMS as a separate branch of healthcare in the country. Over the 100 years of the Institute’s activity, the foundations of its theory and practice have been developed, moreover, a contribution of world significance was made to the EMS development, thereby strengthening the scientific foundation for the activities of the Institute for many years to come.

Quality improvement in emergency medical services: shared experiences of South Africa with pre-war Ukraine

In the Republic of South Africa (RSA) healthcare quality including Emergency Medical Services (EMS) is impaired by scarce resources and variable governance and management. The National Health Quality Improvement Plan (NHQIP) seeks to transform health care quality through standards setting. In RSA EMS managers monitor and adjust quality to comply with the Regulations Relating to Standards for EMS. EMS management training is deficient, and it is unknown how prepared they are to meet quality standards. Object of research: How can the knowledge, attitude, and practice (KAP) of EMS managers be transformed to comply with the standards regulations for EMS. A mixed methods explanatory sequential design was conducted in two phases. Phase one consisted of a KAP quantitative survey (n=352). Phase two included the non-participant observations (N-PO) at country-wide management workshops (n=7 provinces) and interviews (n=11) with key informants/power brokers. The data was analyzed to develop themes to deepen the understanding of the survey data. Fragmentation of EMS into districts; ineffective workforce management; poor fleet management; poorly trained dispatchers, underutilization of information communication technology and vehicle tracking are factors that compromises the access, safety and contribute to ineffective and inefficient EMS. The World Health Organization (2020) report on EMS in Ukraine identified similar challenges. EMS quality challenges in RSA are not unique, and sharing common challenges, experiences and solutions may benefit EMS organizations in other developing countries such as Ukraine.

Organizational factors influencing clinical reasoning in a Swedish emergency medical service organization: An explorative qualitative case study

Introduction Clinical reasoning (CR) among healthcare professionals working in emergency medical services (EMS) who focus on ambulance care is a vital part of ensuring timely and safe patient care. The EMS environment continually fluctuates, so clinicians constantly need to adapt to new situations. Organizational support is described as important for CR, but overall, research on organizational influences for CR in an EMS context is lacking. An increased understanding of these influencing factors can assist in the development of EMS by strengthening CR among clinicians. Therefore, the purpose of this study was to investigate the organizational factors influencing EMS clinicians’ CR. Methods Using a qualitative single case study design, an EMS organization in southwestern Sweden was explored. Data were collected from participant observations of patient encounters, individual and group interviews with clinicians and organizational representatives, and organizational document audits. Data were analyzed using qualitative content analysis and triangulation of data sources. Results The results revealed several organizational influencing factors. Collaboration and information sharing internally and externally were emphasized as essential components influencing CR. Additionally, the structure for the clinicians’ ‘room for action’ appeared confused and created uncertainties for CR related to decision mandates. Conclusion The conclusion is that organizational factors do play an important role in clinicians’ CR. Moreover, the EMS community needs to develop suitable forums for discussing and developing these influencing factors across organizational hierarchies. Finally, clarification is needed on clinicians’ ‘room for action’ within their own organization but also with possible collaborators.

Impact of Point-of-Care Ultrasound on Prehospital Decision Making by HEMS Physicians in Critically Ill and Injured Patients: A Prospective Cohort Study.

Several studies have shown the additional benefit of point-of-care ultrasound (POCUS) by prehospital Emergency Medical Services (EMS). Since organization of EMS may vary significantly across countries, the value of POCUS likely depends on the prehospital system in which it is used. In order to be able to optimally implement POCUS and develop a tailored training curriculum, it is important to know how often POCUS is currently used, for which indications it is used, and how it affects decision making. The aims of this study were: (1) to determine the percentage of patients in whom POCUS was used by Dutch Helicopter Emergency Medical Services (HEMS) crews; (2) to determine how often POCUS findings led to changes in on-scene management; and (3) what these changes were. Patients who received prehospital care from December 1, 2020 through March 31, 2021 by a single HEMS crew were included in this prospective cohort study. Clinical data and specific data on POCUS examination, findings, and therapeutic consequences were collected and analyzed. During the study period, on-scene HEMS care was provided to 612 patients, of which 211 (34.5%) patients underwent POCUS. Of these, 209 (34.2%) patients with a median age of 45 years were included. There were 131 (62.7%) trauma patients, and 70 (33.7%) of the included patients underwent cardiopulmonary resuscitation (CPR). The median reported time of POCUS examination was three (P25-P75 2-5) minutes. Median prolongation of on-scene time was zero (P25-P75 0-1) minutes. In 85 (40.7%) patients, POCUS examination had therapeutic consequence: POCUS was found to impact treatment decisions in 34 (26.0%) trauma patients and 51 (65.4%) non-trauma patients. In patients with cardiac arrest, POCUS was most often used to aid decision making with regard to terminating or continuing resuscitation (28 patients; 13.4%). During the study period, POCUS examination was used in 34.5% of all prehospital HEMS patients and had a therapeutic consequence in 40.7% of patients. In trauma patients, POCUS seems to be most effective for patient triage and evaluation of treatment effectiveness. Moreover, POCUS can be of significant value in patients undergoing CPR. A tailored HEMS POCUS training curriculum should include ultrasound techniques for trauma and cardiac arrest.

‘On the inside I’m grossed out and wanting to puke’: Exploring professional facework and emotional labour as impression management tools in rural emergency medical services

Abstract In the foothills of rural Appalachia, situations arise where emergency medical services (EMS) providers—such as paramedics and emergency medical technicians—must reflect professionalism in their ‘face’. However, as EMS providers practice facework in their organizational roles, it is important to consider how they manage professionalism when emotional labour and dirty work are required, such as when supporting patients from underserved rural communities. Guided by 181 hours of participant observation with 23 interviews with EMS providers from two county-wide EMS organizations, this organizational ethnography reveals the value of impression management strategies in the form of emotional labour. Notably, such practices aid in EMS providers’ maintenance of professional face as they encounter face threats on the job. In such moments, EMS providers utilize emotional labour in their corrective and preventive facework. Importantly, this research makes a meaningful theoretical and practical contribution to organizational communication by illustrating the value of impression management, emotional labour, and facework that aid in the management of professionalism.

Opportunities and barriers for prehospital emergency medical services research in the Netherlands; results of a mixed-methods consensus study

IntroductionQuality improvement in prehospital emergency medical services (EMS) can only be achieved by high-quality research and critical appraisal of current practices. This study examines current opportunities and barriers in EMS research in the Netherlands.MethodsThis mixed-methods consensus study consisted of three phases. The first phase consisted of semi-structured interviews with relevant stakeholders. Thematic analysis of qualitative data derived from these interviews was used to identify main themes, which were subsequently discussed in several online focus groups in the second phase. Output from these discussions was used to shape statements for an online Delphi consensus study among relevant stakeholders in EMS research. Consensus was met if 80% of respondents agreed or disagreed on a particular statement.ResultsForty-nine stakeholders participated in the study; qualitative thematic analysis of the interviews and focus group discussions identified four main themes: (1) data registration and data sharing, (2) laws and regulations, (3) financial aspects and funding, and (4) organization and culture. Qualitative data from the first two phases of the study were used to construct 33 statements for an online Delphi study. Consensus was reached on 21 (64%) statements. Eleven (52%) of these statements pertained to the storage and use of EMS patient data.ConclusionBarriers for prehospital EMS research in the Netherlands include issues regarding the use of patient data, privacy and legislation, funding and research culture in EMS organizations. Opportunities to increase scientific productivity in EMS research include the development of a national strategy for EMS data and the incorporation of EMS topics in research agendas of national medical professional associations.

Factors associated with job satisfaction of emergency medical services professionals – a cross-sectional study

Relevance. Shortage of skilled emergency medical services (EMS) employees is an alarming global problem. EMS missions have increased by fifty percent in many communities. The high EMS demand, low recruitment rate and loss of skilled employees forced EMS organization to explore ways to improve EMS employees work ability and satisfaction. To date there are no data available on EMS employees’ job satisfaction levels in Kuwait. Intention – To establish the national EMS job satisfaction level, identify factors associated with job satisfaction and explore the relationship between job satisfaction, physical wellbeing and depressive disorder. Methodology. A cross-sectional survey was conducted in 80 Kuwait EMS employees online (15 January –15 March 2020). Job satisfaction and depressive disorders were assessed via a questionnaire based on Minnesota Satisfaction Questionnaire (MSQ) that included 21 items. Descriptive and regression analysis were performed. Results and Discussion. The overall mean of job satisfaction was closer to moderate, 3.9 ± 1.4. The participants described the EMS profession to have moderate levels of intrinsic factors except for achievement 1.8 ± 1.5. And to have moderate levels of extrinsic factors except for pay and social factors: overall mean 2.7 ± 1 and 2.2. ± 1.5, respectively. There were three factors associated with job satisfaction: gender (p = < 0.001), career advancement (p = 0.003) and responsibilities (p = 0.005). This analysis also showed significant association between job satisfaction and EMS employees’ well-being (p = 0.001) and absence of depressive disorder (p = < 0.001). Conclusion. There is a moderate level of job satisfaction among EMS workforce in Kuwait. Gender, career advancement and responsibilities were the main factors associated with job satisfaction. Having satisfied EMS employees with their job can eliminate depressive disorder and enhance physical well-being. Future efforts to improve EMS employee’s recruitment, work ability and work quality should reflect on these findings.

The Crowd Crush at Mount Meron: Emergency Medical Services Response to a Silent Mass Casualty Incident.

On April 30, 2021, a total of 45 died and 112 were injured in a crowd crush at a religious festival on Mount Meron, Israel. Unlike a bomb blast, building collapse, mass shooting, or stampede, the incident lacked a dramatic, noticeable trigger and may be termed a "silent mass casualty incident (MCI)." This may have resulted in a slight delay in response. Magen David Adom (MDA)-Israel's National Emergency Medical Services Organization-was the main prehospital response to the MCI. MDA's intense planning, organization of medical infrastructure, and on-site MCI drill before the event allowed for the rapid, coordinated treatment and evacuation of casualties by ambulance and helicopter. The use of volunteers facilitated an effective response to the event. A "rolling reinforcement" system of ambulances helped treat and transport those at the scene while placing staff at stations throughout the country to serve routine emergency calls.

Promoting a health-centered approach to acute mental health crises on college campuses: The case for collegiate-based emergency medical services

As college and university campuses re-open during the COVID-19 pandemic, there is increased concern for mental health crises. Current trends in campus mental health care emphasize providing quality care in a safe, non-judgmental, and non-punitive manner. Collegiate-based emergency medical services organizations are well-positioned to respond to acute mental health crises on college campuses. Campus health professionals and administrators seeking to promote a health-centered approach toward mental health crises should support the growth and development of collegiate-based emergency medical services organizations.

Adverse Health Effects Related to Shift Work Patterns and Work Schedule Tolerance in Emergency Medical Services Personnel: A Scoping Review.

Paramedicine as a profession is continually evolving in clinical practice, responsibilities, and workload. Changes over time in both population demographics and distribution have altered the demand for, and availability of, prehospital emergency medical services (EMS). These factors may also affect scheduling policies in many EMS organizations. However, there is little evidence that suggests optimal shift scheduling patterns to reduce adverse health events such as increased stress or fatigue in prehospital emergency health care providers. Our objective was to describe associations between variations in shift scheduling patterns and EMS provider health outcomes, such as fatigue, stress, sleep quality, and general mental and physiological health. We also sought to identify knowledge gaps. We performed searches of PubMed, CINAHL, Embase, and Cochrane databases for primary studies, systematic reviews, and meta-analyses published between January 2000 and December 2020. Studies reporting measurable health care outcomes in prehospital personnel with defined shift schedule patterns in land-based ambulance systems were included. Our search strategy yielded 188 studies, of which 11 met eligibility criteria (eight cross-sectional surveys, one single case report, one retrospective cohort study, one prospective cohort study, and one systematic review), with one additional study found through reference list screening, leaving 12 studies for review. All publications contained a description of shift schedule characteristics and shared similar outcomes of interest, although there was variation in comparators and assessment of outcomes. Most studies showed high rates of fatigue, stress, mental health concerns, and negative general health outcomes in paramedic shift worker populations. The case study reported improved fatigue, alertness, and sleep quality levels following a switch from a 24-hour shift pattern to an eight-hour shift. We did not complete an in-depth risk of bias assessment for any of the studies. Melnyk evidence ratings varied from IV to VI, indicating a low quality of evidence evaluating the impacts of shift schedule patterns in paramedics, with the retrospective cohort study design, ranked as IV, systematic review as a V, and prospective cohort study, case report and surveys ranked as VI. The low quality and quantity of evidence indicate the need for further research to definitively assess relationships between specific schedule patterns and health outcomes.

Maximizing the Role of Emergency Medical Services in COVID-19 Response.

The Centers for Disease Control and Prevention define 6 intervals of a pandemic: (1) investigation of cases, (2) recognition of the increased potential for ongoing transmission, (3) initiation of a pandemic wave, (4) acceleration of a pandemic wave, (5) deceleration of a pandemic wave, and (6) preparation for future pandemic waves. Each of these stages has 8 domains. Following China's coronavirus disease 2019 (COVID-19) outbreak announcement, Israel's National Emergency Medical Services (EMS) Organization immediately began working in conjunction with the Ministry of Health (MOH) to address the threat of the COVID-19 outbreak. This article will describe how a national EMS organization acted according to these pandemic intervals and domains. In the initial stages, EMS managed a checkpoint in the international airport voluntarily testing people for febrile symptoms. Calls to the dispatch centers that aroused the suspicion of COVID-19 resulted in EMS transport to the hospital with protective gear. During the period of first exposure, the scope of the medical emergency number was increased to include questions concerning coronavirus, telemedicine, and home sampling by protected EMS workers. In the contagion stages, epidemiological tests were conducted by the MOH, and EMS began operating dedicated telephone triage, mass drive-through sampling, and finally, administration of vaccinations.

Are Pelvic Binders an Effective Prehospital Intervention?

Objective Widespread adoption of prehospital pelvic circumferential compression devices (PCCDs) by emergency medical services (EMS) systems has been slow and variable across the United States. We sought to determine the frequency of prehospital PCCD use by EMS providers. Secondarily, we hypothesized that prehospital PCCD use would improve early hemorrhagic shock outcomes. Methods We conducted a single-center retrospective cohort study of 162 unstable pelvic ring injuries transported directly to our center by EMS from 2011 to 2020. Included patients received a PCCD during their resuscitation (prehospital or emergency department). Prehospital treatment details were obtained from the EMS medical record. The primary outcome was the proportion of patients who received a PCCD by EMS before hospital arrival. Secondarily, we explored factors associated with receiving a prehospital PCCD, and its association with changes in vital signs, blood transfusion, and mortality. Results EMS providers documented suspicion of a pelvic ring fracture in 85 (52.8%) patients and 52 patients in the cohort (32.2%) received a prehospital PCCD. Wide variation in prehospital PCCD use was observed based on patient characteristics, geographic location, and EMS provider level. Helicopter flight paramedics applied a prehospital PCCD in 46% of the patients they transported (38/83); in contrast, the EMS organizations geographically closest to our hospital applied a PCCD in ≤5% of cases (2/47). Other predictors associated with receiving a prehospital PCCD included lower body mass index (p = 0.005), longer prehospital duration (p = 0.001) and lower Injury Severity Score (p < 0.05). We were unable to identify any improvements in clinical outcomes associated with prehospital PCCD, including early vital signs, number of blood transfusions within 24 hours, or mortality during admission (p > 0.05). Conclusion Our results demonstrate wide practice variation in the application of prehospital PCCDs. Although disparate PCCD application across the state is likely explained by differences across EMS organizations and provider levels, our study was unable to identify any clinical benefits to the prehospital use of PCCDs. It is possible that the benefits of a prehospital PCCD can only be observed in the most displaced fracture patterns with the greatest early hemodynamic instability.

Responses of a Pre-hospital Emergency Medical Service During Military Conflict Versus COVID-19: A Retrospective Comparative Cohort Study.

ABSTRACTBackgroundDecreases in routine healthcare practices have been shown to occur during disasters. However, research regarding the impacts of natural disasters, pandemics, or military conflicts on emergency medical services (EMS) is scarce.ObjectivesThis study assessed the impact of a military conflict versus the coronavirus disease 2019 (COVID-19) pandemic on a national EMS organization in terms of responses to overall daily emergencies, medical illnesses, motor vehicle collisions, and other injuries.MethodsThis retrospective comparative cohort study assessed daily routine emergency ambulance calls to Magen David Adom (MDA), Israel’s national EMS organization. This included overall emergency calls as well as those related to medical illnesses, motor vehicle collisions (MVCs), and other injuries. All data were obtained from the MDA command and control database. During the military conflict Operation Protective Edge (2014), the civilian population was subjected to intensive rocket attacks for 24 days, followed by 26 days of a progressive withdrawal of operations and then to a post-conflict period. During the first wave of the COVID-19 pandemic (March-April 2020), the population was subjected to 32 days of total lockdown, followed by 27 days of progressive relief of confinement, and then to a post-lockdown period.ResultsThe total number of emergency calls in this study was 330,430. During the conflict, the mean number of daily calls decreased, followed by an increase during Relief and Post-Conflict with higher values in Post-Conflict than in Pre-Conflict. During the COVID-19 pandemic, there was a decrease in the mean daily number of calls during Lockdown. It remained low during Relief and increased during Post-Lockdown. However, it remained lower in Post-Lockdown than during Pre-Lockdown. Calls related to medical illnesses decreased during the conflict and during the lockdown. The post-conflict period was characterized by a similar baseline call magnitude but not during the post-lockdown period. Decreases in calls for MVC and other injuries were significant during the lockdown but not during the military conflict. Post-lockdown was accompanied by return to baseline call volumes for MVC, whereas calls for other injuries increased above baseline both after the lockdown and military conflict.ConclusionThis study shows decreasing trends in routine daily calls for EMS during both Operation Protective Edge and COVID-19. However, different patterns of needs for EMS were evidenced for medical illnesses, MVC, or calls concerning other injuries. These results are instrumental for managing the operational demands of EMS during military conflicts and pandemics.

Adherence to Psychological First Aid after Exposure to a Traumatic Event at Work among EMS Workers: A Qualitative Study.

Managing post-traumatic stress reactions in the first few days after exposure to a potentially traumatic event in the course of one’s work remains a challenge for first responder organizations such as Emergency Medical Services (EMS). Psychological First Aid (PFA) is an evidence-informed approach to reducing initial distress and promoting short- and long-term coping strategies among staff in the aftermath of exposure. PFA provided by peer helpers is considered a promising solution for first responder organizations. Unfortunately, first responders may encounter stigma and barriers to mental health care. Therefore, a deeper investigation is needed regarding adherence over time to implemented PFA intervention. The purpose of this study is to qualitatively explore factors that influence adherence to PFA intervention of recipients and peer helpers. EMS workers (n = 11), working as PFA peer helpers for one year, participated in semi-structured interviews. Data were analyzed using thematic analysis; intercoder reliability (κ = 0.91) was also used. Researchers identified four themes and 11 subthemes influencing adherence to PFA intervention: (1) individual perceptions and attitudes of peer helpers and recipients about pfa intervention; (2) perceived impacts on peer helpers and recipients; (3) organizational support to pfa intervention; and (4) congruence with the occupational culture. Study findings herein suggest that it is conceivable to act on various factors to improve adherence to PFA intervention among peer helpers and recipients within EMS organization. This could lead to enhanced understanding of the challenges involved in sustaining a peer led PFA program for first responders.

Out-of-hospital cardiac arrest and ambient air pollution: A dose-effect relationship and an association with OHCA incidence.

Pollution has been suggested as a precipitating factor for cardiovascular diseases. However, data about the link between air pollution and the risk of out-of-hospital cardiac arrest (OHCA) are limited and controversial. By collecting data both in the OHCA registry and in the database of the regional agency for environmental protection (ARPA) of the Lombardy region, all medical OHCAs and the mean daily concentration of pollutants including fine particulate matter (PM10, PM2.5), benzene (C6H6), carbon monoxide (CO), nitrogen dioxide (NO2), sulphur dioxide (SO2), and ozone (O3) were considered from January 1st to December 31st, 2019 in the southern part of the Lombardy region (provinces of Pavia, Lodi, Cremona and Mantua; 7863 km2; about 1550000 inhabitants). Days were divided into high or low incidence of OHCA according to the median value. A Probit dose-response analysis and both uni- and multivariable logistic regression models were provided for each pollutant. The concentrations of all the pollutants were significantly higher in days with high incidence of OHCA except for O3, which showed a significant countertrend. After correcting for temperature, a significant dose-response relationship was demonstrated for all the pollutants examined. All the pollutants were also strongly associated with high incidence of OHCA in multivariable analysis with correction for temperature, humidity, and day-to-day concentration changes. Our results clarify the link between pollutants and the acute risk of cardiac arrest suggesting the need of both improving the air quality and integrating pollution data in future models for the organization of emergency medical services.

Optimizing Emergency Medical Service Structures Using a Rule-Based Discrete Event Simulation-A Practitioner's Point of View.

Many studies in research deal with optimizing emergency medical services (EMS) on both the operational and the strategic level. It is the purpose of this method-oriented article to explain the major features of “rule-based discrete event simulation” (rule-based DES), which we developed independently in Germany and Switzerland. Our rule-based DES addresses questions concerning the location and relocation of ambulances, dispatching and routing policies, and EMS interplay with other players in prehospital care. We highlight three typical use cases from a practitioner’s perspective and go into different countries’ peculiarities. We show how research results are applied to EMS and healthcare organizations to simulate and optimize specific regions in Germany and Switzerland with their strong federal structures. The rule-based DES serves as basis for decision support to improve regional emergency services’ efficiency without increasing cost. Finally, all simulation-based methods suggest normative solutions and optimize EMS’ performance within given healthcare system structures. We argue that interactions between EMS, emergency departments, and public healthcare agencies are crucial to further improving effectiveness, efficiency, and quality.

Strategies to Handle Increased Demand in the COVID-19 Crisis: A Coronavirus EMS Support Track and a Web-Based Self-Triage System

Background In emergencies, such as the COVID-19 pandemic, there is an increased need for contact with emergency medical services (EMS), and call volume might surpass capacity. The Copenhagen EMS operates two telephone line the 1-1-2 emergency number and the 1813 medical helpline. A separate coronavirus support track was implemented on the 1813 medical helpline and a web-based self-triage (web triage) system was created to reduce non-emergency call volume. The aim of this paper is to present call volume and the two measures implemented to handle the increased call volume to the Copenhagen EMS. Methods This is a cross sectional observational study. Call volume and queue time is presented in the first month of the COVID-19 pandemic (27th of February 2020 to 27th of march) and compared to the equivalent month from the year before (2019). Descriptive statistics are conducted on call volumes and queue times and spearman’s rank correlation test are performed to test correlation between web triage and call volume. Results Total EMS call volume increase by 23.3% between 2019 and 2020 (92.670 vs. 114,250). The 1-1-2 emergency line total call volume increase by 4.4% (8,4942 vs. 8,870) and the 1813 medical helpline increased by 25.1% (84.176 vs. 105.380). The coronavirus support track handled 21,063 calls. The 1813 medical helpline queue time was a mean of 02 minutes and 23 seconds (CI: 2.22-2.25) in 2019 and 12 minutes and 2 seconds (CI 11:55-12:09) in 2020 (P < 0.001). The web triage was used 10,894 times. No correlation between call volume and web triage usage was seen. Conclusions In the first month of the ongoing COVID-19 pandemic a significant increase in call volume was observed in the 1813 medical helpline compared to 2019. A large number of calls were handled by the additional coronavirus track and diverted away from the regular tracks of the 1813 medical helpline. This likely contributed to mitigating increased call volumes and queue times. The web triage was widely used but no significant correlation was seen with 1813 medical helpline call volume. Other EMS organizations can learn from this to enhance capacity in a future epidemics.

The Role of Emergency Medical Services in Earthquake Response: Integrating the ABC Approach of Israel's Magen David Adom.

Throughout history, earthquakes have caused devastation and loss of life. Emergency medical services (EMS) plays a vital role in the response to any mass-casualty incident or disaster. Magen David Adom, Israel's premier EMS organization, has a unique strategy known as the ABC approach to earthquake response. It involves thousands of salaried workers and trained volunteers who are prepared to respond to an earthquake based on the extent of the disaster. Depending on the amount of destruction, they will be working locally or available to help in other areas. A Level A earthquake causes local destruction and minimal casualties. Any EMS responders in that area as well as in surrounding areas will be available to help. Furthermore, all responders will need to work automatically and autonomously. A Level B earthquake causes extensive destruction, and all responders in the region will be busy caring for the victims. Anyone available outside of the region will come and help. A Level C earthquake is completely devastating, and all workers nationwide will be involved in responding to the catastrophe. The role of EMS responders using the ABC approach to earthquake response, as described here, may be integrated in part or whole in other EMS systems.
