State-Based Evaluation of the Workforce Pipeline from Paramedic Program Enrollment to Agency Affiliation.

OBJECTIVES: The strength and stability of the paramedic workforce is dependent on the continual flow of EMS clinicians into the field. Workforce entry requires three distinct steps: program completion, certification attainment, and affiliation with an EMS agency. At each of these steps, future EMS clinicians may be lost to the workforce but the contribution of each is unknown. Our objective was to evaluate these inflection points using a state-based registry of EMS clinicians from their point of entry into the EMS education system to eventual EMS agency affiliation.METHODS: This is a retrospective cohort evaluation of paramedic students in the Commonwealth of Virginia. We included any student who enrolled in a paramedic program in 2017 or 2018. Data were provided by the Virginia Office of Emergency Medical Services, who tracks the development of EMS clinicians from the point of entry into an educational program through their affiliation with an EMS agency upon employment. Our primary outcomes include proportions of enrolled students who complete a program, graduating students who attain national/state certification, and nationally certified EMS clinicians who affiliate with an EMS agency. Proportions were calculated at each step and compared to the overall population of students enrolled.RESULTS: In 2017 and 2018, 775 and 603 students were enrolled in paramedic programs, respectively. Approximately a quarter of students did not complete their paramedic program (2017: 25% [192/775]; 2018: 28% [170/603]). Of those who graduated, the proportion of students not gaining certification was lower (2017: 11% [62/583]; 2018: 17% [75/433]). Of those who certified, those not affiliating was similarly low (2017: 15% [77/521]; 2018: 13% [46/358]). Evaluating the effect of each of these steps on the total entry into the workforce, nearly half of those who originally enrolled did not join the workforce through agency affiliation (2017: 43% [331/775]; 2018: 48% [291/603]).CONCLUSIONS: There are multiple areas to enhance retention of potential EMS trainees from program enrollment to EMS agency affiliation. This analysis suggests that educational attrition has a larger impact on the availability of new paramedics than certification examinations or agency affiliation decisions, though is limited to a singular state evaluation.

Effect of COVID-19 Pandemic Lockdown on Emergency Medical Service Utilisation, and Percutaneous Coronary Intervention Volume-An Australian Perspective.

BACKGROUND: Acute coronary syndrome (ACS) admissions and percutaneous coronary intervention (PCI) volume declined during periods of COVID-19 lockdown internationally in 2020. The effect of lockdown on emergency medical service (EMS) utilisation, and PCI volume during the initial phase of the pandemic in Australia has not been well described. METHOD: We analysed data from the Victorian Cardiac Outcomes Registry (VCOR), a state-wide PCI registry, linked with the Ambulance Victoria EMS registry. PCI volume, 30-day major adverse cardiovascular and cerebrovascular events (MACCE; composite of mortality, myocardial infarction, stent thrombosis, unplanned revascularisation, and stroke), and EMS utilisation were compared over four time periods: lockdown (26 Mar 2020-12 May 2020); pre-lockdown (26 Feb 2020-25 Mar 2020); post-lockdown (13 May 2020-10 Jul 2020); and the year prior (26 Mar 2019-12 May 2019). Interrupted time series analysis was performed to assess PCI trends within and between consecutive periods. RESULTS: The EMS utilisation for ACS during lockdown was higher compared with other periods: lockdown 39.4% vs pre-lockdown 29.7%; vs post-lockdown 33.6%; vs year prior 27.1%; all p<0.01. Median daily PCI cases were similar: 31 (IQR 10, 38) during lockdown; 39 (15, 49) pre-lockdown; 39.5 (11, 44) post-lockdown; and, 42 (10, 49) the year prior; all p>0.05. Median door-to-procedure time for ACS indication during lockdown was shorter at 3 hours (1.2, 20.6) vs pre-lockdown 3.9 (1.7, 21); vs post-lockdown 3.5 (1.5, 21.26); and, the year prior 3.5 (1.5, 23.7); all p<0.05. Lockdown period was associated with lower odds for 30-day MACCE compared to pre-lockdown (odds ratio [OR] 0.55 [0.33-0.93]; p=0.026); post-lockdown (OR 0.66; [0.40-1.06]; p=0.087); and the year prior (OR 0.55 [0.33-0.93]; p=0.026). CONCLUSIONS: Contrary to international trends, EMS utilisation for ACS increased during lockdown but PCI volumes remained similar throughout the initial stages of the pandemic in Victoria, with no observed adverse effect on 30-day MACCE during lockdown. These data suggest that the public health response in Victoria was not associated with poorer quality cardiovascular care in patients receiving PCI.

Exploring the Effectiveness of Emergency Medical Services Becoming Active in Fall Prevention: A Literature Review.

Falls, particularly among the elderly, are a prevalent and growing healthcare issue in the United States. Individuals who experience falls face heightened morbidity and mortality risks, along with substantial expenses associated with managing any resulting injuries. First responders frequently respond to 911 calls related to falls, with a significant portion of these cases not resulting in hospital or healthcare facility transfers. As such, many fall victims receive treatment without any preventive measures being implemented. The purpose of this review is to explore the current studies that examine whether Emergency Medical Service personnel can effectively act in fall prevention. While earlier studies present conflicting findings, recent research indicates the potential for preventive strategies that go beyond mere referrals.

Shift in emergency department utilization by frequent attendees with sickle cell disease during the COVID-19 pandemic: A multicentre cohort study.

While the coronavirus disease-2019 (COVID-19) might have increased acute episodes in people living with sickle cell disease (SCD), it may also have changed their reliance on emergency department (ED) services. We assessed the impact of the COVID-19 pandemic and lockdowns on ED visits in adult SCD people followed in five French reference centres, with a special focus on 'high users' (≥10 visits in 2019). We analysed the rate of ED visits from 1 January 2015 to 31 December 2021, using a self-controlled case series. Among 1530 people (17 829 ED visits), we observed a significant reduction in ED visits during and after lockdowns, but the effect vanished over time. Compared to pre-pandemic, incidence rate ratios for ED visits were 0.59 [95% CI 0.52-0.67] for the first lockdown, 0.66 [95% CI 0.58-0.75] for the second and 0.85 [95% CI 0.73-0.99] for the third. High users (4% of people but 33.7% of visits) mainly drove the reductions after the first lockdown. COVID-19 lockdowns were associated with reduced ED visits. While most people returned to their baseline utilization by April 2021, high users had a lasting decrease in ED visits. Understanding the factors driving the drop in ED utilization among high users might inform clinical practice and health policy.

[Prehospital Care Times and Interventions for Victims of Major Trauma in the Central Region of Portugal: A Retrospective Study]. / Tempos de Resposta e Intervenções Extra-Hospitalar à Vítima de Trauma Major na Região Centro de Portugal: Um Estudo Retrospetivo.

INTRODUCTION: The quality and promptness of prehospital care for major trauma patients are vital in order to lower their high mortality rate. However, the effectiveness of this response in Portugal is unknown. The objective of this study was to analyze response times and interventions for major trauma patients in the central region of Portugal. METHODS: This was a retrospective, descriptive study, using the 2022 clinical records of the National Institute of Medical Emergency's differentiated resources. Cases of death prior to arrival at the hospital and other non-transport situations were excluded. Five-time intervals were determined, among which are the response time (T1, between activation and arrival at the scene), on-scene time (T2), and transportation time (T5; between the decision to transport and arrival at the emergency service). For each ambulance type, averages and dispersion times were calculated, as well as the proportion of cases in which the nationally and internationally recommended times were met. The frequency of recording six key interventions was also assessed. RESULTS: Of the 3366 records, 602 were eliminated (384 due to death), resulting in 2764 cases: nurse-technician ambulance (SIV) = 36.0%, physician- nurse ambulance (VMER) = 62.2% and physician-nurse helicopter = 1.8%. In a very large number of records, it was not possible to determine prehospital care times: for example, transport time (T5) could be determined in only 29%, 13% and 8% of cases, respectively for SIV, VMER and helicopter. The recommended time for stabilization (T2 ≤ 20 min) was met in 19.8% (SIV), 36.5% (VMER) and 18.2% (helicopter). Time to hospital (T5 ≤ 45 min) was achieved in 80.0% (SIV), 93.1% (VMER) and 75.0% (helicopter) of the records. The administration of analgesia (42% in SIV) and measures to prevent hypothermia (23.5% in SIV) were the most recorded interventions. CONCLUSION: There was substantial missing data on statuses and a lack of information in the records, especially in the VMER and helicopter. According to the records, the time taken to stabilize the victim on-scene often exceeded the recommendations, while the time taken to transport them to the hospital tended to be within the recommendations.

Introdução: A qualidade e rapidez do socorro pré-hospitalar à pessoa vítima de trauma major é vital para diminuir a sua elevada mortalidade. Contudo, desconhece-se a efetividade desta resposta em Portugal. O objetivo deste estudo foi analisar os tempos de resposta e as intervenções realizadas às vítimas de trauma major na região centro de Portugal. Métodos: Estudo retrospetivo, descritivo, utilizando os registos clínicos de 2022 dos meios diferenciados do Instituto Nacional de Emergência Médica. Casos de óbito pré-chegada ao hospital e outras situações de não transporte foram excluídos. Determinaram-se cinco tempos, entre os quais o tempo de resposta (T1, decorrente entre acionamento e chegada ao local), o tempo no local (T2) e o tempo de transporte (T5, intervalo entre a decisão de transporte e a chegada ao serviço de urgência). Foram calculadas médias e medidas de dispersão para cada meio, bem como a proporção de casos em que foram cumpridos os tempos recomendados nacional e internacionalmente. Avaliou-se também a frequência de registo de seis intervenções chave. Resultados: Dos 3366 registos, eliminaram-se 602 (384 por óbito), resultando em 2764 casos [suporte imediato de vida (SIV) = 36,0%, viaturas médicas de emergência e reanimação (VMER) = 62,2%, helicóptero de emergência médica (HEM) = 1,8%]. Num elevado número de registos não foi possível determinar tempos de socorro: por exemplo, o tempo de transporte (T5) foi determinável em apenas 29%, 13%, e 8% dos casos, respetivamente para SIV, VMER e HEM. O tempo recomendado para a estabilização (T2 ≤ 20 min), foi cumprido em 19,8% (SIV), 36,5% (VMER), e 18,2% (HEM) dos regis- tos. Já o tempo de transporte (T5 ≤ 45 min) foi cumprido em 80,0% (SIV), 93,1% (VMER) e 75,0% (HEM) dos registos (avaliáveis). A administração de analgesia (42% na SIV) e as medidas de prevenção de hipotermia (23,5% na SIV) foram as intervenções mais registadas. Conclusão: Observaram-se muitos status omissos e falta de informação nos registos, sobretudo na VMER e HEM. De acordo com os registos, o tempo no local superou frequentemente as recomendações, enquanto o tempo de transporte tende a estar dentro das normas.

A scenario based approach to optimizing cost-effectiveness of physician-staffed Helicopter Emergency Medical Services compared to ground-based Emergency Medical Services in Finland.

OBJECTIVES: Since Helicopter Emergency Medical Services (HEMS) is an expensive resource in terms of unit price compared to ground-based Emergency Medical Service (EMS), it is important to further investigate which methods would allow for the optimization of these services. The aim of this study was to evaluate the cost-effectiveness of physician-staffed HEMS compared to ground-based EMS in developed scenarios with improvements in triage, aviation performance, and the inclusion of ischemic stroke patients. METHODS: Incremental cost-effectiveness ratio (ICER) was assessed by comparing health outcomes and costs of HEMS versus ground-based EMS across six different scenarios. Estimated 30-day mortality and quality-adjusted life years (QALYs) were used to measure health benefits. Quality-of-Life (QoL) was assessed with EuroQoL instrument, and a one-way sensitivity analysis was carried out across different patient groups. Survival estimates were evaluated from the national FinnHEMS database, with cost analysis based on the most recent financial reports. RESULTS: The best outcome was achieved in Scenario 3.1 which included a reduction in over-alerts, aviation performance enhancement, and assessment of ischemic stroke patients. This scenario yielded 1077.07-1436.09 additional QALYs with an ICER of 33,703-44,937 €/QALY. This represented a 27.72% increase in the additional QALYs and a 21.05% reduction in the ICER compared to the current practice. CONCLUSIONS: The cost-effectiveness of HEMS can be highly improved by adding stroke patients into the dispatch criteria, as the overall costs are fixed, and the cost-effectiveness is determined based on the utilization rate of capacity.

Emergency physicians' and nurses' perception on the adequacy of emergency calls for nursing home residents: a non-interventional prospective study.

Introduction: A considerable percentage of daily emergency calls are for nursing home residents. With the ageing of the overall European population, an increase in emergency calls and interventions in nursing homes (NH) is to be expected. A proportion of these interventions and hospital transfers may be preventable and could be considered as inappropriate by prehospital emergency medical personnel. The study aimed to understand Belgian emergency physicians' and emergency nurses' perspectives on emergency calls and interventions in NHs and investigate factors contributing to their perception of inappropriateness. Methods: An exploratory non-interventional prospective study was conducted in Belgium among emergency physicians and emergency nurses, currently working in prehospital emergency medicine. Electronic questionnaires were sent out in September, October and November 2023. Descriptive statistics were used to analyze the overall results, as well as to compare the answers between emergency physicians and emergency nurses about certain topics. Results: A total of 114 emergency physicians and 78 nurses responded to the survey. The mean age was 38 years with a mean working experience of 10 years in prehospital healthcare. Nursing home staff were perceived as understaffed and lacking in competence, with an impact on patient care especially during nights and weekends. General practitioners were perceived as insufficiently involved in the patient's care, as well as often unavailable in times of need, leading to activation of Emergency Medical Services (EMS) and transfers of nursing home residents to the Emergency Department (ED). Advance directives were almost never available at EMS interventions and transfers were often not in accordance with the patient's wishes. Palliative care and pain treatment were perceived as insufficient. Emergency physicians and nurses felt mostly disappointed and frustrated. Additionally, differences in perception were noted between emergency physicians and nurses regarding certain topics. Emergency nurses were more convinced that the nursing home physician should be available 24/7 and that transfers could be avoided if nursing home staff had more authority regarding medical interventions. Emergency nurses were also more under the impression that pain management was inadequate, and emergency physicians were more afraid of the medical implications of doing too little during interventions than emergency nurses. Suggestions to reduce the number of EMS interventions were more general practitioner involvement (82%), better nursing home staff education/competences (77%), more nursing home staff (67%), mobile palliative care support teams (65%) and mobile geriatric nursing intervention teams (52%). Discussion and conclusion: EMS interventions in nursing homes were almost never seen as necessary or indicated by emergency physicians and nurses, with the appropriate EMS level almost never being activated. The following key issues were found: shortages in numbers and competence of nursing home staff, insufficient primary care due to the unavailability of the general practitioner as well as a lack of involvement in patient care, and an absence of readily available advance directives. General practitioners should be more involved in the decision to call the Emergency Medical Services (EMS) and to transfer nursing home residents to the Emergency Department. Healthcare workers should strive for vigilance regarding the patients' wishes. The emotional burden of deciding on an avoidable hospital admission of nursing home residents, perhaps out of fear for medico-legal consequences if doing too little, leaves the emergency physicians and nurses frustrated and disappointed. Improvements in nursing home staffing, more acute and chronic general practitioner consultations, and mobile geriatric and palliative care support teams are potential solutions. Further research should focus on the structural improvement of the above-mentioned shortcomings.

Ambulance professionals' experiences of teamwork in the context of a team training programme - a qualitative study.

BACKGROUND: Teamwork in the context of ambulance services exhibits unique characteristics, as this environment involves a small core team that must adapt to a dynamic team structure that involves health care professionals and emergency services. It is essential to acquire a deeper understanding of how ambulance teams operate. Therefore, this study aimed to explore the experiences of ambulance professionals with teamwork and how they were influenced by the implementation of a team training programme. METHODS: A qualitative descriptive study was conducted involving ambulance professionals who took part in focus group interviews carried out both before and after the implementation of a team training program across seven ambulance stations within a Norwegian hospital trust. The data were analysed using reflexive thematic analysis based on a deductive-inductive approach. RESULTS: Our analysis revealed 15 subthemes that characterised ambulance professionals' experiences with teamwork and a team training programme, which were organised according to the five main themes of team structure, communication, leadership, situation monitoring, and mutual support. Ambulance professionals' experiences ranged from the significance of team composition and interpersonal and professional relationships to their preferences regarding different communication styles and the necessity of team leaders within the ambulance service. The team training programme raised awareness of teamwork, while the adoption of teamwork tools was influenced by both individual and contextual factors. The Introduction/Identity, Situation, Background, Assessment and Recommendation (ISBAR) communication tool was identified as the most beneficial aspect of the programme due to its ease of use, which led to improvements in the structure and quality of consultations and information handover. CONCLUSIONS: This study documented the diverse characteristics and preferences associated with teamwork among ambulance professionals, emphasising the particular importance of proficient partnerships in this context. Participation in a team training programme was perceived as a valuable reminder of the significance of teamwork, thus providing a foundation for the enhancement of communication skills.

Changes in Nursing Staff Levels and Injury-Related Emergency Department Visits among Assisted Living Residents with Alzheimers Disease and Related Dementias.

OBJECTIVES: To examine the relationship between changes in nursing staff-hours per resident-day and injury-related emergency department (ED) visits among assisted living (AL) residents with Alzheimer disease and related dementias (ADRD). DESIGN: Retrospective cohort study. SETTING AND PARTICIPANTS: We leveraged a data set of AL community characteristics in Ohio linked to Medicare claims data from 2007 to 2015. METHODS: We estimated Poisson models examining the relationships of personal care aide, registered nurse (RN), licensed practical nurse (LPN), and total nursing hours with injury-related ED visits. Models were adjusted for resident characteristics (ie, age, race, sex, dual eligibility, presence and number of chronic conditions), AL community characteristics (percentage of residents on Medicaid, average resident acuity), year fixed effects, and assisted living fixed effects. We examined all injury-related ED visits and injury-related ED visits resulting in hospital admission as separate outcomes. RESULTS: The sample included 122,700 person-months, representing 12,144 fee-for-service Medicare beneficiaries with ADRD within 455 different AL communities in Ohio between 2007 and 2015. Median total nursing hours increased from 1.34 in 2007 to 1.69 in 2015. In the fully adjusted model, an increase in 1 RN-hour per resident-day was associated with a decrease in the risk of any injury-related ED visit (incidence rate ratio 0.59, 95% CI 0.36-0.96), representing a 53% decrease. Changes in RN-hours were not associated with injury-related inpatient hospitalizations. Changes in total nursing, LPN, and personal care aide hours were not associated with changes in the risk of injury-related ED visits or inpatient hospitalizations. CONCLUSIONS AND IMPLICATIONS: Increases in RN staffing hours were associated with reduced injury-related ED use among AL residents with ADRD. RNs provide surveillance and care oversight that may help mitigate injury risk, and they are able to physically assess residents at the time of a fall and/or injury, which can preempt unnecessary ED transfers.

Primary care doctors in acute call-outs to severe trauma incidents in Norway - variations by rural-urban settings and time factors.

BACKGROUND: A severely injured patient needs fast transportation to a hospital that can provide definitive care. In Norway, approximately 20% of the population live in rural areas. Primary care doctors (PCDs) play an important role in prehospital trauma care. The aim of this study was to investigate how variations in PCD call-outs to severe trauma incidents in Norway were associated with rural-urban settings and time factors. METHODS: In this study on severe trauma patients admitted to Norwegian hospitals from 2012 to 2018, we linked data from four official Norwegian registries. Through this, we investigated the call-out responses of PCDs to severe trauma incidents. In multivariable log-binomial regression models, we investigated whether factors related to rural-urban settings and time factors were associated with PCD call-outs. RESULTS: There was a significantly higher probability of PCD call-outs to severe trauma incidents in the municipalities in the four most rural centrality categories compared to the most urban category. The largest difference in adjusted relative risk (95% confidence interval (CI)) was 2.08 (1.27-3.41) for centrality category four. PCDs had a significantly higher proportion of call-outs in the Western (RR = 1.46 (1.23-1.73)) and Central Norway (RR = 1.30 (1.08-1.58)) Regional Health Authority areas compared to in the South-Eastern area. We observed a large variation (0.47 to 4.71) in call-out rates to severe trauma incidents per 100,000 inhabitants per year across the 16 Emergency Medical Communication Centre areas in Norway. CONCLUSIONS: Centrality affects the proportion of PCD call-outs to severe trauma incidents, and call-out rates were higher in rural than in urban areas. We found no significant difference in call-out rates according to time factors. Possible consequences of these findings should be further investigated.

The impact of time to defibrillation on return of spontaneous circulation in out-of-hospital cardiac arrest patients with recurrent shockable rhythms.

OBJECTIVE: Optimal timing for subsequent defibrillation attempts for Out-of-hospital cardiac arrest (OHCA) patients with recurrent VF/pVT is uncertain. We investigated the relationship between VF/pVT duration and return of spontaneous circulation (ROSC) in OHCA patients with recurrent shockable rhythms. METHODS: We analyzed data from the Salt Lake City Fire Department (SLCFD) spanning from 2012 to 2023. The implementation of rhythm-filtering technology since 2011 enabled real-time rhythm interpretation during CPR, with local protocols allowing early defibrillation for recurrent/refractory VF/pVT cases. We included patients experiencing four or five episodes of VF and pVT rhythms and employed generalized estimating equation (GEE) regression analysis to examine the association between VF/pVT durations preceding recurrent defibrillation and return of spontaneous circulation (ROSC). RESULTS: Analysis of 622 appropriate shocks showed that patients achieving ROSC had significantly shorter median VF/pVT duration than those who did not achieve ROSC (0.83 minutes vs. 1.2 minutes, p = 0.004). Adjusted analysis of those with 4 VF/pVT episodes (N = 142) revealed that longer VF/pVT durations were associated with lower odds of achieving ROSC (odds ratio: 0.81, 95% CI: 0.72-0.93, p = 0.005). Every one-minute delay in intra-arrest defibrillation is predicted to decrease the likelihood of achieving ROSC by 19%. CONCLUSION: Every one-minute increase in intra-arrest VF/pVT duration was associated with a statistically significant 19% decrease in the chance of achieving ROSC. This highlights the importance of reducing time to shock in managing recurrent VF/pVT. The findings suggest reevaluating the current recommendations of two minutes intervals for rhythm check and shock delivery.

Mapping prehospital clinician impression to hospital-based diagnoses in children transported to the hospital by emergency medical services.

Objectives: Emergency medical services (EMS) serves a critical role in the delivery of services to children with out-of-hospital emergencies. The EMS clinicians' initial field diagnoses, termed "impressions", facilitate focused patient assessments, guide the application of prehospital treatment protocols, and help determine transport destination. We sought to evaluate the concordance of the EMS clinician impression to a child's hospital-based diagnosis.Methods: We retrospectively studied de-identified pediatric (<18 years old) scene runs transported to the hospital and with available linked hospital data from the 2021 ESO Data Collaborative, a multi-agency prehospital electronic health record dataset. EMS impressions and primary emergency department or admission-based diagnoses were categorized into one of twenty-one major groups in the Diagnosis Grouping System. We identified the most common hospital-based discharge diagnoses and evaluated for the agreement between EMS impression and hospital-based diagnosis using Cohen's Kappa statistic.Results: We included 35,833 pediatric transports from the scene with linked prehospital and in-hospital data (median age 11 years, interquartile range, 3-15 years; 50.9% male). The most common categories for both EMS impressions and hospital-based diagnoses were as follows respectively: trauma (26.1%; 24.6%), neurologic diseases (18.9%; 16.4%), psychiatric and behavioral diseases and substance use disorder (11.8%; 11.6%), and respiratory diseases (11.1% and 9.5%). A total of 23,224 out of 35,833 patients, or 64.8%, had concordant EMS impressions and hospital-based diagnoses. There was high agreement between common EMS impression and in-hospital diagnoses (trauma 77.3%; neurologic diseases 70.3%; respiratory diseases 64.5%; and psychiatric, behavioral disease and substance use disorder 73.9%). Hospital-based diagnoses demonstrated moderate concordance with prehospital data (Cohen's κ = 0.59).Conclusions: We found moderate concordance between EMS primary impression and hospital diagnoses. The EMS encounter is brief and without capabilities of advanced testing, but initial impressions may influence the basis of the triage assignment and interventions during the hospital-based encounter. By evaluating EMS impressions and ultimate hospital diagnoses, pediatric protocols may be streamlined, and specific training emphasized in pursuit of improving patient outcomes. Future work is needed to examine instances of discordance and evaluate the impact on patient care and outcomes.

Sex Disparities in Resuscitation Quality Following Out of Hospital Cardiac Arrest.

BACKGROUND: Women are known to be disadvantaged compared with men in the early links of the Chain of Survival, receiving fewer bystander interventions. We aimed to describe sex-based disparities in emergency medical service resuscitation quality and processes of care for out-of-hospital cardiac arrest. METHODS AND RESULTS: We conducted a retrospective analysis of patients who were nontraumatic with out-of-hospital cardiac arrest aged ≥16 years where resuscitation was attempted between March 2019 and June 2023. We investigated 18 routinely captured performance metrics and performed adjusted logistic and quantile regression analyses to assess sex-based differences in these metrics. During the study period, 10 161 patients with out-of-hospital cardiac arrest met the eligibility criteria, of whom 3216 (32%) were women. There were no clinically relevant sex-based differences observed in regard to external cardiac compressions; however, women were 34% less likely to achieve a systolic blood pressure >100 mm Hg on arrival at the hospital (adjusted odds ratio [AOR], 0.66 [95% CI, 0.47-0.92]). Furthermore, women had a longer time to 12-lead ECG acquisition after return of spontaneous circulation (median adjusted difference, 1.00 minute [95% CI, 0.38-1.62]) and 33% reduced odds of being transported to a 24-hour percutaneous coronary intervention-capable facility (AOR, 0.67 [95% CI, 0.49-0.91]). Resuscitation was also terminated sooner for women compared with men (median adjusted difference, -4.82 minutes [95% CI, -6.77 to -2.87]). CONCLUSIONS: Although external cardiac compression quality did not vary by sex, significant sex-based disparities were seen in emergency medical services processes of care following out-of-hospital cardiac arrest. Further investigation is required to elucidate the underlying causes of these differences and examine their influence on patient outcomes.

Effect of timing of advanced life support on out-of-hospital cardiac arrests at home in Japan.

AIM: In cases of out-of-hospital cardiac arrests (OHCA) occurring at home, Japanese emergency medical services personnel decide whether to provide treatment on the scene or during transport based on their judgment. This study aimed to evaluate the association between the timing of advanced life support (ALS) (i.e., endotracheal intubation [ETI] or adrenaline administration) for OHCA at home and prognosis. METHOD: This retrospective cohort study used data from the Japan Utstein Registry and emergency transport data collected from patients who underwent pre-hospital ETI (n = 6806) and received adrenaline (n = 22,636) between 2016 and 2019. The timing of ETI or adrenaline administration was determined as "on the scene" or "in the ambulance." Multiple logistic regression analysis was used to estimate the association among the timing of ALS implementation, pre-hospital return of spontaneous circulation (ROSC), and survival at 1 month. RESULT: ETI on the scene was significantly positively associated with pre-hospital ROSC (adjusted odds ratio [AOR], 1.81; 95% confidence interval [CI], 1.57-2.09) and survival at 1 month (AOR, 1.81; 95% CI, 1.47-2.23). Adrenaline administration on the scene was significantly positively associated with pre-hospital ROSC (AOR, 2.51; 95% CI, 2.33-2.70) and survival at 1 month (AOR, 2.13; 95% CI, 1.89-2.40). CONCLUSION: Our analysis suggests performing ALS on the scene was associated with pre-hospital ROSC and survival at 1 month. Further efforts are needed to increase the rate of ALS implementation on the scene by emergency life-saving technicians.

Evaluation of basic life support interventions for foreign body airway obstructions: A population-based cohort study.

AIM: To quantify the associations of foreign body airway obstruction (FBAO) basic life support (BLS) interventions with FBAO relief and survival to discharge. METHODS: We identified prehospital FBAO patient encounters in Alberta, Canada between Jan 1, 2018 and Dec 31,2021 using the provincial emergency medical services' medical records, deterministically linked to hospital data. Two physicians reviewed encounters to determine cases and extract data. Multivariable logistic regression determined the adjusted odds ratio of FBAO relief (primary outcome) and survival to discharge for the exposure of BLS interventions (abdominal thrusts [AT], chest compressions/thrusts [CC], or combinations) relative to back blows [BB]. Intervention-associated injuries were identified using International Classification of Diseases codes, followed by health records review. RESULTS: We identified 3,677 patient encounters, including 709 FBAOs requiring intervention. Bystanders performed the initial BLS intervention in 488 cases (77.4%). Bystanders and paramedics did not relieve the FBAO in 151 (23.5%) and 11 (16.7%) cases, respectively. FBAOs not relieved before paramedic arrival had a higher proportion of deaths (n = 4[0.4%] versus n = 92[42.4%], p < 0.001). AT and CC were associated with decreased odds of FBAO relief relative to BB (adjusted odds ratio [aOR] 0.49 [95%CI 0.30-0.80] and 0.14 [95%CI 0.07-0.28], respectively). CC were associated with decreased odds of survival to discharge (aOR 0.04 [95%CI 0.01-0.32]). AT, CC, and BB were implicated in intervention-associated injuries in four, nine, and zero cases, respectively. CONCLUSIONS: Back blows are associated with improved outcomes compared to abdominal thrusts and chest compressions. These data can inform prospective studies aimed at improving response to choking emergencies.

Emergency reflex action drill for traumatic cardiac arrest in a simulated pre-hospital setting; a one-group pre-post intervention study.

BACKGROUND: Emergency Reflex Action Drills (ERADs) are meant to decrease stress-associated cognitive demand in high urgency situations. The aim of this study was to develop and test an ERAD for witnessed traumatic cardiac arrest (TCA), an event in which potentially reversible causes need to be systematically addressed and treated in a short period of time. We hypothesize that this ERAD (the TCA-Drill) helps ground Emergency Medical Services (EMS) nurses in overcoming performance decline during this specific high-pressure situation. METHODS: This was a prospective, experimental one-group pre-post intervention study. Ground EMS nurses participated in a session of four simulated scenarios, with an in-between educational session to teach the TCA-Drill. Scenarios were video recorded, after which adherence and time differences were analyzed. Self-confidence on clinical practice was measured before and after the scenarios. RESULTS: Twelve ground EMS nurses participated in this study. Overall median time to address reversible causes of TCA decreased significantly using the TCA-Drill (132 vs. 110 s; p = 0.030) compared with the conventional ALS strategy. More specifically, participants adhering to the TCA-Drill showed a significantly lower time needed for hemorrhage control (58 vs. 37 s; p = 0.012). Eight of 12 (67 %) ground EMS nurses performed the ERAD without protocol deviations. Reported self-confidence significantly increased on 11 of the 13 surveyed items. CONCLUSIONS: The use of an ERAD for TCA (the TCA-Drill) significantly reduces the time to address reversible causes for TCA without delaying chest compressions in a simulated environment and can be easily taught to ground EMS nurses and increases self-confidence. IMPLICATIONS FOR CLINICAL PRACTICE: The use of an ERAD for TCA (the TCA-Drill can significantly reduce the time to address reversible causes for TCA without delaying chest compression. This drill can be easily taught to ground EMS nurses and increases their self-confidence in addressing TCA-patients.

Social mass gathering events influence emergency medical services call volume.

Background: Prior literature suggests that mass gathering events pose challenges to an emergency medical services (EMS) system. We aimed to investigate whether events influence EMS call rates. Materials and methods: This study is a retrospective review of all primary response ambulance calls in Rhode Island (US) between January 1st, 2018 and August 31st, 2022. The number of EMS calls per day was taken from the state's EMS registry. Event data was collected using a Google (Google LLC, Mountain View, CA) search. We used separate Poisson regression models with the number of ambulance calls as the dependent and the social event categories sports, agricultural, music events, and public exhibitions as independent variables. All models controlled for the population at risk and the period of the COVID-19 pandemic. Results are presented as increases or decreases in calls per 100,000 inhabitants from the mean over the study period. Results: The mean number of daily EMS calls was 38 ± 4 per 100,000 inhabitants. EMS encountered significantly more missions on days with music events (+3, 95% CI [2; 3]) and public exhibitions (+2, 95% CI [1; 2]). In contrast, days with agricultural events were associated with fewer calls (-1, 95% CI [-1; 0]). We did not find any effect of sports events on call rates. Conclusion: Increased ambulance call volumes are observed on days with music events and public exhibitions. Days with agricultural events are associated with fewer EMS calls.

Disparity in guideline adherence for prehospital care according to patient age in emergency medical service transport for moderate to severe trauma.

OBJECTIVES: The aim of this study was to investigate the association between patient age and guideline adherence for prehospital care in emergency medical services (EMS) for moderate to severe trauma. METHODS: This was a retrospective observational study that used a nationwide EMS-based trauma database from 2016 to 2019. Adult trauma patients whose injury severity score was greater than or equal to nine were screened, and those with cardiac arrest or without outcome data were excluded. The enrolled patients were categorized into four groups according to patient age: young (<45 years), middle-aged (45-64 years), old (65-84 years), and very old (>84 years). The primary outcome was guideline adherence, which was defined as following all prehospital care components: airway management for level of consciousness below verbal response, oxygen supply for pulse oximetry under 94 %, intravenous fluid administration for systolic blood pressure under 90 mmHg, scene resuscitation time within 10 min, and transport to the trauma center or level 1 emergency department. Multivariable logistic regression was conducted to calculate the adjusted odds ratios (aORs) and 95 % confidence intervals (95 % CIs). RESULTS: Among the 430,365 EMS-treated trauma patients, 38,580 patients were analyzed-9,573 (24.8 %) in the young group, 15,296 (39.7 %) in the middle-aged group, 9,562 (24.8 %) in the old group, and 4,149 (10.8 %) in the very old group. The main analysis revealed a lower probability of guideline adherence in the old group (aOR 95 % CI = 0.84 (0.76-0.94)) and very old group (aOR 95 % CI = 0.68 (0.58-0.81)) than in the young group. CONCLUSION: We found disparities in guideline adherence for prehospital care according to patient age at the time of EMS assessment of moderate to severe trauma. Considering this disparity, the prehospital trauma triage and management for older patients needs to be improved and educated to EMS providers.

The Road to 988/911 Interoperability: Three Case Studies on Call Transfer, Colocation, and Community Response.

The 988 Suicide and Crisis Lifeline-known more simply as 988-holds promise for significantly improving the mental health of Americans and accelerating the decriminalization of mental illness. However, the rapid transition to 988 has left many gaps as communities scramble to prepare-not the least of which includes determining how 988 will interface with local 911 response systems and law enforcement. 911 is often the default option for individuals experiencing mental health emergencies, despite the fact that 911 call centers have limited resources to address behavioral health crises. Since 988 launched in 2022, one key area of focus has been ways that jurisdictions approach 988/911 interoperability: the existence of formal protocols, procedures, or agreements that allow for the transfer of calls from 988 to 911 and vice versa. This study presents case studies from three jurisdictions that have established models of 988/911 interoperability. It provides details related to interoperability in each model, including the role of each agency, points of interagency communication, and decision points that can affect the way a call flows through the local system. It also identifies facilitators, barriers, and equity-related considerations of each jurisdiction's approach, as well as lessons learned from implementation. This study should be of interest to jurisdictions that are looking to implement 988/911 interoperability, including those that are spearheading local initiatives and those that are responding to state-level legislation. Its findings are relevant to 988 call centers, public safety answering points, mobile crisis units, law enforcement, and local and state decisionmakers.

Role identities of emergency medical services personnel and their associations with intention to leave the profession.

BACKGROUND: The scope of emergency medical services (EMS) has expanded from the urgent care of emergency patients to on-call healthcare services provided in the field with a holistic view of the patient's wellbeing. This challenges EMS to find solutions to cover all demands, while simultaneously setting high skill requirements for EMS personnel. Understanding personnel is a critical element in developing functional and resistant EMS. The aim of this study was to investigate how Finnish EMS personnel emphasize the Emergency Medical Services Role Identity Scale aspects of caregiving, thrill-seeking, duty, and capacity; and if these role identities are associated with intention to leave the profession. METHODS: We conducted a cross-sectional survey (N = 616, 52% women, mean age 32.9 years). Data were collected through social media platforms and analyzed with means, standard deviations, Mann-Whitney U-tests, Kruskal-Wallis H-tests, and binary logistic regression analyses. RESULTS: Our results indicate that capacity is the most emphasized aspect among EMS personnel, and at the same time, it increases intention to leave EMS. Capacity was followed by caregiving, with no association with intention to leave. Duty and thrill-seeking were the least emphasized and were negatively associated with intention to leave. Additionally, there were also other factors that were associated with emphasizing EMS-RIS aspect and intention to leave. CONCLUSION: Capacity stands out most strongly in analysis being at the core of the role identity of EMS personnel and was associated with a higher likelihood of leaving intentions. Several other factors were also associated with the intention to leave. Future studies should examine the exact dimensions of capacity that are considered important among EMS personnel and why factors such as work experience are associated with intentions to leave.
