OBJECTIVE: Hemorrhage is the leading cause of preventable death in civilian trauma centers and on the battlefield. One of the emerging treatment options for hemorrhage in austere environments is tranexamic acid (TXA). However, the landscape is not amenable to the current delivery standard. This study compared the pharmacokinetics of TXA via a standard 10-minute intravenous infusion (IV infusion), intravenous rapid push over 10 s (IV push), and intramuscular injection (IM) in a swine polytrauma and hemorrhagic shock model (trauma group) compared to uninjured controls (control group)...

Improving health and safety in our communities requires deliberate focus and commitment to equity. Inequities are differences in access, treatment, and outcomes between individuals and across populations that are systemic, avoidable, and unjust. Within health care in general, and Emergency Medical Services (EMS) in particular, there are demonstrated inequities in the quality of care provided to patients based on a number of characteristics linked to discrimination, exclusion, or bias. Given the critical role that EMS plays within the health care system, it is imperative that EMS systems reduce inequities by delivering evidence-based, high-quality care for the communities and patients we serve...

Introduction: Asthma exacerbations are a common cause of pediatric Emergency Medical Services (EMS) encounters. Accordingly, prehospital management of pediatric asthma exacerbations has been designated an EMS research priority. However, accurate identification of pediatric asthma exacerbations from the prehospital record is nuanced and difficult due to the heterogeneity of asthma symptoms, especially in children. Therefore, this study's objective was to develop a prehospital-specific pediatric asthma computable phenotype (CP) that could accurately identify prehospital encounters for pediatric asthma exacerbations...

Objective: The prehospital treatment for stable patients with atrial fibrillation with rapid ventricular response is rate-controlling agents such as calcium channel blockers, often diltiazem given as a bolus. At our agency we encourage the use of a bolus given via the infusion pump over two to four minutes immediately followed by maintenance infusion, given concerns of recurrent tachycardia or hypotension secondary to rapid bolus administration. We examined if administering a bolus and infusion via an infusion pump shows better heart rate (HR) control at arrival to the emergency department (ED) compared with administration of a bolus only, while maintaining hemodynamic stability during transport...

OBJECTIVES: Emergency medical services (EMS) systems increasingly grapple with rising call volumes and workforce shortages, forcing systems to decide which responses may be delayed. Limited research has linked dispatch codes, on-scene findings, and emergency department (ED) outcomes. This study evaluated the association between dispatch categorizations and time-critical EMS responses defined by prehospital interventions and ED outcomes. Secondarily, we proposed a framework for identifying dispatch categorizations that are safe or unsafe to hold in queue...

INTRODUCTION: Early administration of antibiotics for open fractures reduces serious bone and soft tissue infections. The effectiveness of antibiotics in reducing these infections is time-dependent, with various surgical associations recommending administration within one hour of injury, or within one hour of patient arrival to the emergency department (ED). The extent to which prehospital antibiotic administration in these situations might reduce the time to treatment has not been previously reported...

OBJECTIVE: Out-of-hospital cardiac arrest (OHCA) is a major health problem and one of the leading causes of death in adults older than 40. Multiple prior studies have demonstrated survival disparities based on race/ethnicity, but most of these focus on a single racial/ethnic group. This study evaluated OHCA variables and outcomes among on 5 racial/ethnic groups. METHODS: This is a retrospective review of data for adult patients in the Cardiac Arrest Registry to Enhance Survival (CARES) from 3 racially diverse urban counties in the San Francisco Bay Area from May 2009 to October 2021...

OBJECTIVE: Current guidelines recommend that patients presenting with ST-elevation myocardial infarction (STEMI) to hospitals not capable of performing primary percutaneous coronary intervention (PCI) be transferred to a PCI-capable hospital if reperfusion can be accomplished within 120 minutes. Most STEMI patients are accompanied by an advanced care paramedic (ACP, equivalent to EMT-P), nurse, or physician who can manage complications should they arise. In our region, stable STEMI patients are transported by primary care paramedics (PCPs, similar scope of practice to advanced EMT) in cases where a nurse, physician, or ACP paramedic is not available...

Objectives: The risk of falls increases with age and often requires an emergency medical service (EMS) response. We compared the characteristics of patients attended by EMS in response to repeat falls within 30 days and 12 months of their first EMS-attended fall; and explored the number of days between the index fall and the subsequent fall(s). Methods: This retrospective cohort study included all adults (> =18 years of age) who experienced their first EMS-attended fall between 1st January 2016 and 31st December 2020, followed up until 31 December 2021...

INTRODUCTION: Behavioral health emergencies (BHEs) are a common patient encounter for emergency medical services (EMS) clinicians and other first responders, in particular law enforcement (LE) officers. It is critical for EMS clinicians to have management strategies for BHEs, yet relatively little information exists on best practices. In 2016, the Los Angeles County EMS Agency's Commission initiated a comprehensive evaluation of the 9-1-1 response for BHEs and developed a plan for improving the quality of care and safety for patients and first responders...

Objective: Previous investigations of the relationship between obesity and difficult airway management have provided mixed results. Almost universally, these studies were conducted in the hospital setting, and the influence of patient body weight on successful prehospital airway management remains unclear. Because patient weight could be one readily identifiable risk factor for problematic airway interventions, we sought to evaluate this relationship. Methods: We conducted a retrospective analysis using the 2020 ESO Data Collaborative dataset...

Introduction: We report a case of accelerated idioventricular rhythm (AIVR) identified by Emergency Medical Services (EMS) monitoring of an infant presenting with lethargy and respiratory distress. Accelerated idioventricular rhythms are rare ventricular rhythms originating from the His-Purkinje system or ventricular myocytes, consisting of >3 monomorphic beats with gradual onset and termination. 1 An AIVR is usually well-tolerated and does not require treatment, though sustained arrythmia may induce syncope, and the rhythm has been seen in newborn infants with congenital heart diseases...

Background. Children have differing utilization of emergency medical services (EMS) by socioeconomic status. We evaluated differences in prehospital care among children by the Child Opportunity Index (COI), the agreement between a child's COI at the scene and at home, and in-hospital outcomes for children by COI. Methods. We performed a retrospective study of pediatric (<18 years) scene encounters from approximately 2,000 United States EMS agencies from the 2021-2022 ESO Data Collaborative. We evaluated socioeconomic status using the multi-dimensional COI v2...

Objective: Emergency services utilization is increasing in older adult populations. Many such encounters may be preventable with better access to acute care in the community. Mobile integrated health (MIH) programs leverage mobile resources to deliver care and services to patients in the out-of-hospital environment and have the potential to improve clinical outcomes and decrease health care costs; however, they have not been widely implemented. We assessed barriers, potential facilitators, and other factors critical to the implementation of MIH programs with key vested partners...

Objective: To evaluate the Shock Index (SI) as a predictive tool for triage of gastrointestinal bleeding (GI) in the prehospital setting, assessing its correlation with mortality, admission rates, and hospital length of stay. Methods: In this retrospective cohort study, we analyzed data from the ESO Data Collaborative encompassing EMS records from the year 2022, focusing on 1525 patients with a primary GI bleeding diagnosis. The primary measure was the SI, calculated at initial contact and highest recorded prior to ED arrival...

BACKGROUND: Pelvic fractures resulting from high-energy trauma can frequently present with life-threatening hemodynamic instability that is associated with high mortality rates. The role of pelvic exsanguination in causing hemorrhagic shock is unclear, as associated injuries frequently accompany pelvic fractures. This study aims to compare the incidence of hemorrhagic shock and in-hospital outcomes in patients with isolated and non-isolated pelvic fractures. METHODS: Registries-based study of trauma patients hospitalized following pelvic fractures...

INTRODUCTION: The use of transcutaneous pacing (TCP) for unstable bradycardia has a class 2B recommendation from the American Heart Association. Prior studies have not adequately described the frequency or possible causes of treatment failure. EMS clinicians and leaders have reported false electrical capture as a potential cause. In this study, we aimed to describe the frequency of true electrical capture, documented verification of mechanical capture, and its association with systolic blood pressure (SBP) and survival...

Background: Position statements from national organizations commonly vary in methodology for the evaluation of existing literature and the development of recommendations. Recent national recommendations have highlighted important components for evidence-based guidelines that can be feasibly incorporated in the creation of position statements and their resource documents. We describe the methodology developed to guide the creation of a compendium of 16 trauma-related position statements led by NAEMSP and partner organizations...
