Assistance time and peripheral oxygen saturation in prehospital emergency data as predictors of COVID19 hospital outcomes.

To verify if data obtained in the prehospital evaluation of patients with severe acute respiratory syndrome (SARS) during the initial response to the COVID-19 pandemic is associated with clinical outcomes: mechanical ventilation, hospital discharge, and death. This is a retrospective analysis involving secondary data from the Emergency Medical Service (EMS) records and the Health Surveillance Information System of patients assisted by the EMS in Manaus, from January to June 2020, the period of the first peak of COVID-19 cases. The combination of the two databases yielded a total of 1.190 patients, who received a first EMS response and were later admitted to hospital with SARS and had data on clinical outcomes of interest available. Patients were predominantly male (754, 63.4%), with a median age of 66 (IQR: 54.0-78.0) years. SARS illness before medical assistance was associated to need for invasive mechanical ventilation (IMV, p < 0.001). Lower pre-hospital SpO2 was associated to death (p = 0.025). Death was more common among patients with respiratory support needs, especially in the invasive ventilation group (262/287; 91.3%) (p < 0.001). In addition, IMV was more common among elderly individuals (p < 0.001). Patients admitted to ICU had a greater chance of dying when compared to non-ICU admitted patients (p < 0.001), and closely related to IMV (p < 0.001). Patients in ICU were also older (p = 0.003) and had longer hospital stay (p < 0.001). Mortality was associated with mechanical ventilation (p < 0.001), ICU admission (p < 0.001), and older age (p < 0.001). Patients who died had a shorter length of both ICU and total hospital stay (p < 0.001). Prehospital EMS may provide feasible and early recognition of critical patients with SARS in strained healthcare systems, such as in low-resource settings and pandemics.

Exploring Prehospital Data for Pandemic Preparedness: A Western Brazilian Amazon Case Study on COVID-19.

BACKGROUND: The timely management of rapidly evolving epidemiological scenarios caused by disease outbreaks is crucial to prevent devastating consequences. However, delayed laboratory diagnostics can hamper swift health policy and epidemic response, especially in remote regions such as the western Brazilian Amazon. The aim of the article is to analyze the impact of the COVID-19 pandemic on the volume and characteristics of emergency medical services (EMS) in Manaus, focusing on how the pandemic affected sensitive indicators such as response time and the use of advanced life support ambulances. Additionally, the study seeks to understand how changes in prehospital EMS patterns, triggered by the pandemic, could be utilized as health surveillance tools, enabling a more rapid response in epidemic scenarios. METHODS: This retrospective, descriptive study included data from the SAMU (Serviço de Atendimento Móvel de Urgência) medical records between January and June 2020. RESULTS: A total of 45,581 calls resulted in mobile units being dispatched during this period. These patients were predominantly male (28,227, 61.9%), with a median age of 47 years (IQR 30-67). The median response time significantly increased during the pandemic, reaching a median of 45.9 min (IQR 30.6-67.7) (p < 0.001). EMS calls were reduced for trauma patients and increased for other medical emergencies, especially respiratory conditions, concomitantly to an escalation in the number of deaths caused by SARS and COVID-19 (p < 0.001). The employment of advanced life support ambulances was higher during the pandemic phase (p = 0.0007). CONCLUSION: The COVID-19 pandemic resulted in a temporary disorder in the volume and reason for EMS calls in Manaus. Consequently, sensitive indicators like the response time and the employment of advanced life support ambulances were negatively affected. Sudden prehospital EMS pattern changes could play an important role in health surveillance systems, allowing for earlier establishment of countermeasures in epidemics. The impact of the COVID-19 pandemic on prehospital EMS and its role in health surveillance should be further explored.

Characteristics of the out-of-hospital cardiac arrest attended by the medical emergency services in Medellín. A population-based retrospective cohort study / Características del paro cardiaco extrahospitalario atendido por operadores de ambulancias en Medellín. Estudio de cohorte retrospectivo de base poblacional

Abstract Introduction: Every year, five million people around the world experience an out-of-hospital cardiac arrest (OHCA) and less than 40 % receive any assistance before the arrival of the Emergency Medical Services (EMS). Ambulance operators (AO) take care of people experiencing an OHCA, stabilize and then transfer them. In Medellín, Colombia, there is a public AO and several private providers, but the information about an OHCA and the operational characteristics during the response to the event are limited. Objective: To estimate the incidence of OHCA and to explore the factors associated with survival after the event in Medellín city. Methods: Retrospective, population-based cohort study. All the medical records of patients experiencing an OHCA who were assessed and treated by ambulance operators, (AO) of the Emergency Medical Services (EMS) and private agencies in Medellin city were reviewed. Descriptive statistics were used for data analysis and the annual incidence of the event standardized for the general population was estimated. Potential survival-associated factors reported as OR with their corresponding 95% CI were explored. Results: A total of 1,447 patient records with OHCA between 2018 and 2019 were analyzed. The event incidence rate for the number of cases assessed was 28.1 (95 % CI 26.0-30.3) and 26.9 (95 % CI 24.929.1) cases per 100,000 inhabitants/year for 2018 and 2019, respectively; the incidence rate of treated OHCA was 2.6 (95 % CI 2.0-3.3) and 3.2 (95 % CI 2.5-4.0) per 100,000 inhabitants/year, for 2018 and 2019. Survival on arrival at hospitals of treated cases was 14.2 % (95 % CI 5.5-22.8) and 15.5 % (95 % CI 7.4-23.5) for 2018 and 2019, respectively. Conclusions: This study portrays the operating and care characteristics of the population experiencing OHCA in Medellín city. The incidence rate of the event and the survival were lower than those reported in the literature.

Resumen Introducción: Cada año, cinco millones de personas en el mundo presentan paro cardiaco prehospitalario (PCEH), de los cuales menos del 40 % reciben ayuda antes de la llegada de los sistemas de emergencia médica (SEM). Los operadores de ambulancias (OA) atienden a los que sufren un PCEH, su estabilización y posterior traslado. En Medellín, Colombia, existe un OA público y agencias privadas, pero la información acerca del PCEH y las características operacionales durante la respuesta a este evento es escasa. Objetivo: Estimar la incidencia del PCEH y explorar factores asociados a la supervivencia del evento en la ciudad de Medellín. Métodos: Estudio de cohorte retrospectivo de base poblacional. Se revisaron todos los registros médicos de pacientes que presentaron un PCEH que fueron evaluados y tratados por OA del SEM y de agencias privadas de Medellín. Se usaron estadísticos descriptivos para los datos y se estimó la incidencia anual del evento estandarizada para la población general. Se exploraron posibles factores asociados a la supervivencia, reportados como OR con su respectivos IC 95 %. Resultados: Se analizaron 1.447 registros de pacientes con PCEH presentados entre 2018 y 2019. La tasa de incidencia del evento para los casos evaluados fue de 28,1 (IC 95 % 26,0-30,3) y 26,9 (IC 95 % 24,9-29,1) casos por 100.000 habitantes/año, para 2018 y 2019, respectivamente; la tasa de incidencia del PCEH tratado fue de 2,6 (IC 95 % 2,0-3,3) y 3,2 (IC 95 % 2,5-4,0) por 100.000 habitantes/año, para 2018 y 2019. La supervivencia a la llegada a los hospitales de los casos tratados fue 14,2 % (IC 95 % 5,5-22,8) y del 15,5 % (IC 95 % 7,4-23,5) para 2018 y 2019, respectivamente. Conclusiones: Se muestra las características operativas y de atención de la población que presenta un PCEH en Medellín. La tasa de incidencia del evento y la supervivencia fueron menores a las reportadas en la literatura.

Field trauma triage criteria associated with need for dedicated trauma center care: a single-center retrospective cohort study.

INTRODUCTION: Direct transport from the scene of injury to a trauma centre reduces saves lives. In Ontario, paramedics use the field trauma triage standard (FTTS) to determine if a patient meets trauma bypass criteria. Recent studies have questioned the efficacy of the FTTS in identifying severely injured patients. The objective of this study was to determine the predictive performance of the FTTS on the need for trauma center care in patients who were transported to a trauma center. METHODS: This was a single-center health records study of patients transported by ambulance directly to a level 1 trauma center. Hospital based trauma center need and injury severity score-based need were defined. Bivariate associations with one or more FTTS criteria were tested using the Wilcoxon two-sample test for continuous variables, and the Chi-square or Fisher's exact test for categorical indicators. The sensitivity and specificity of each category of the FTTS were calculated. RESULTS: There were 1427 patients included in the study, with 76% men, mean age of 40, and 76% had a blunt mechanism. The overall sensitivity and specificity of the FTTS was 90.9% and 20.8% for hospital-based need and 91.6% and 20.3 for injury severity need. The most sensitive variable for hospital-based need was physiologic criteria (53.7). Mechanism of injury was the most sensitive criteria for injury severity need (54.8). Physiological criteria had the highest association with hospital-based and injury severity need (adjusted odds ratios 7.5 [95% CI 5.8-9.8] and 5.1 [95% CI 3.9-6.7]). CONCLUSIONS: The FTTS has fair performance in identifying the need for hospital-based and injury severity need. Systolic blood pressure less than 90 mmHg, Glasgow Coma Scale (motor) less than 6, and falls greater than 6 m were most predictive of trauma center need. Improving prehospital trauma triage is critical to ensure timely transport to a trauma centre.

RéSUMé: INTRODUCTION: Le transport direct de la scène de la blessure à un centre de traumatologie permet de sauver des vies. En Ontario, les ambulanciers paramédicaux utilisent la norme de triage des traumatismes sur le terrain (FTTS) pour déterminer si un patient répond aux critères de pontage traumatique. Des études récentes ont remis en question l'efficacité du FTTS dans l'identification des patients gravement blessés. L'objectif de cette étude était de déterminer la performance prédictive du FTTS sur le besoin de soins en centre de traumatologie chez les patients qui ont été transportés dans un centre de traumatologie. MéTHODES: Il s'agissait d'une étude des dossiers médicaux d'un seul centre portant sur des patients transportés par ambulance directement à un centre de traumatologie de niveau 1. Les besoins des centres de traumatologie hospitaliers et les besoins basés sur le score de gravité des blessures ont été définis. Les associations bivariées avec un ou plusieurs critères FTTS ont été testées à l'aide du test à deux échantillons de Wilcoxon pour les variables continues et du test de Fisher pour les indicateurs catégoriels. La sensibilité et la spécificité de chaque catégorie du FTTS ont été calculées. RéSULTATS: Il y avait 1427 patients inclus dans l'étude, avec 76% d'hommes, âge moyen de 40, et 76% avaient un mécanisme émoussé. La sensibilité et la spécificité globales du FTTS étaient de 90,9 % et de 20,8 % pour les besoins hospitaliers et de 91,6 % et de 20,3 % pour les besoins de gravité des blessures. La variable la plus sensible pour les besoins hospitaliers était les critères physiologiques (53,7). Le mécanisme de blessure était le critère le plus sensible pour le besoin de gravité de la blessure (54,8). Les critères physiologiques étaient les plus associés aux besoins hospitaliers et aux besoins en matière de gravité des blessures (rapports de cotes ajustés de 7,5 [IC à 95 % 5,8-9,8] et 5,1 [IC à 95 % 3,9-6,7]). CONCLUSION: Le FTTS a un rendement équitable pour ce qui est de déterminer le besoin de soins hospitaliers et de gravité des blessures. La pression artérielle systolique inférieure à 90mmHg, l'échelle de coma de Glasgow (moteur) inférieure à 6 et les chutes supérieures à 6m étaient les plus prédictives des besoins du centre de traumatologie. L'amélioration du triage des traumatismes avant l'hospitalisation est essentielle pour assurer un transport rapide vers un centre de traumatologie.

A low-cost, DIY tourniquet simulator with built-in self-assessment for prehospital providers in Guatemala city.

BACKGROUND: Hemorrhage is the leading cause of preventable death after trauma. In high-income countries first responders are trained in hemorrhage control techniques but this is not the case for developing countries like Guatemala. We present a low-cost training model for tourniquet application using a combination of virtual and physical components. METHODS: The training program includes a mobile application with didactic materials, videos and a gamified virtual reality environment for learning. Additionally, a physical training model of a bleeding lower extremity is developed allowing learners to practice tourniquet application using inexpensive and accessible materials. Validation of the simulator occurred through content and construct validation. Content validation involved subjective assessments by novices and experts, construct validation compared pre-training novices with experts. Training validation compared pre and post training novices for improvement. RESULTS: Our findings indicate that users found the simulator useful, realistic, and satisfactory. We found significant differences in tourniquet application skills between pre-training novices and experts. When comparing pre- and post-training novices, we found a significantly lower bleeding control time between the groups. CONCLUSION: This study suggests that this training approach can enhance access to life-saving skills for prehospital personnel. The inclusion of self-assessment components enables self-regulated learning and reduces the need for continuous instructor presence. Future improvements involve refining the tourniquet model, validating it with first-responder end users, and expanding the training program to include other skills.

Women Abused: Analysis of Assistance Provided by Urgency Mobile Service.

Considering that reports of violence against women must come after a victim seeks help, the subject matter transcends health-related issues. In Brazil, mobile urgency services (SAMU/SIATE) frequently provide first aid to these women and, to the best of our knowledge, no other research has specifically examined the first reaction given to these women. The present study aimed to analyze SAMU/SIATE assistance to abused women in a cross-sectional study of the assistance to assaulted women provided by SIATE and SAMU Maringá/Norte Novo between 2011 and 2020. Women between 20 and 39 years old, non-pregnant, were the main victims, and 19.52% of them have used drugs of some kind. The (ex) partner figured as the perpetrator in 17.35%, but there was no information about this variable in 73.75% of the records. The Chi-square test shows a mortality rate superior to 70% among the severely traumatized victims. This is the first research work to examine the kind of care that SAMU/SIATE offers, and it identifies several weaknesses in its "modus operandi" that may prevent the results from being applied to larger contexts. In addition, further studies on mobile urgent care services in other provinces are required in order to suggest ways to lessen this epidemic.

Team climate and job satisfaction in a mobile emergency service: a multilevel study / Clima en equipo y satisfacción laboral en un servicio de atención móvil de urgencia: estudio multinivel / Clima em equipe e satisfação no trabalho em um serviço de atendimento móvel de urgência: estudo multinível

Objective: to investigate the relationship between team climate and job satisfaction among professionals working in mobile pre-hospital care. Method: this is a quantitative, correlational study carried out in a mobile pre-hospital care service in the São Paulo Metropolitan Region. The participants were 95 professionals, allocated to 40 teams, who answered three questionnaires: sociodemographic/labor data, Team Climate Scale and S20/23 Job Satisfaction Scale. Descriptive statistics and multilevel linear models were used for the analysis, including moderation effects. The Backward method was used to ascertain the order of significance. Results: in the models, the relationships between satisfaction with hierarchical relationships and the factor "support for new ideas" moderated for men and "task orientation" for women were significant. For satisfaction with the physical environment, "working hours" and "participation in the team" were significant and, for intrinsic satisfaction, the regime, working hours and the factors "team objectives", "participation in the team" and "support for new ideas" remained significant, as did the moderation effect between length of service, "participation in the team" and "support for new ideas". Conclusion: team climate is influenced by job satisfaction in a heterogeneous way and the moderating effect of this relationship is associated with gender and length of service.

Objetivo: examinar la relación entre el clima en equipo y la satisfacción laboral de los profesionales que trabajan en servicios de atención prehospitalaria móvil. Método: estudio cuantitativo y correlacional realizado en un servicio de atención prehospitalaria móvil en la Región Metropolitana de São Paulo. Participaron 95 profesionales, distribuidos en 40 equipos, que respondieron a tres cuestionarios: datos sociodemográficos/laborales, Escalas de Clima en Equipo y de Satisfacción Laboral S20/23. Para el análisis, se utilizaron estadísticas descriptivas y modelos lineales multiniveles, incluyendo efectos de moderación. Se empleó el método Backward para determinar el orden de significancia. Resultados: en los modelos, fueron significativas las relaciones entre la satisfacción con las relaciones jerárquicas y el factor "apoyo para nuevas ideas" moderado por el género masculino y "orientación hacia las tareas" en mujeres. Para la satisfacción con el ambiente físico, fueron significativos "jornada laboral" y "participación en el equipo", y para la satisfacción intrínseca, se mantuvieron significativos el régimen, la jornada y los factores "objetivos del equipo", "participación en el equipo" y "apoyo para ideas nuevas", y el efecto de moderación entre el tiempo de actuación, "participación en el equipo" y "apoyo para ideas nuevas". Conclusión: el clima en equipo es influenciado por la satisfacción laboral de manera heterogénea y el efecto moderador de esta relación se asocia con el género y el tiempo de actuación en el servicio.

Abstract Objective To investigate the status quo and analyze the influencing factors of the knowledge, attitude, and practice of pre-hospital emergency among caregivers for older adults. Methods In this cross-sectional study, 133 caregivers for older adults in Guangdong province, China, nursing homes were selected as survey participants from December 2021 to June 2022 via convenience sampling. All participants were administered a general information questionnaire and a Pre-Hospital Emergency Knowledge, Attitude, and Practice Questionnaire. For data analysis, we used descriptive and inferential statistics. Results The scores on the knowledge, attitude, and practice dimensions were 24.65 ± 4.49, 24.52 ± 4.34, and 24.05 ± 4.67, respectively. Regression analysis showed that the age, professional skill level, and healthcare education experience of the caregivers were the main influencing factors of their pre-hospital emergency knowledge. Additionally, the presence/absence of direct participation in the pre-hospital emergency of the caregivers was the primary influencing factor of attitude, while education level and employment status were the factors mainly influencing pre-hospital emergency practice. Conclusion Caregivers for older adults currently have a low-to-medium level of knowledge, attitude, and practice of pre-hospital emergency. The main factors affecting the implementation of pre-hospital emergency for caregivers in China are their older age, low education levels, temporary employment and imperfect occupational security system.

Prehospital blood transfusion in Brazil: results of the first year of implementation in an emergency medical service.

INTRODUCTION: Hemorrhagic shock is the main cause of death in the prehospital environment, which highlights the need to standardize measures aiming at bleeding control and volume replacement in this environment. In Brazil, the first prehospital packed red blood cell transfusion service started in September 2020, in Bragança Paulista, state of São Paulo. OBJECTIVES: Describe the trends and characteristics of patients who received prehospital transfusions prior to hospital treatment during the first year of operation. METHODS: A retrospective data review was made of all patients who received transfusions from the mobile intensive care unit in Bragança Paulista over one year. RESULTS: In this period, 19 patients were transfused. Since activation, the average response time was 20 min. The mean shock indexes before and after blood transfusion were 2.16 and 1.1, respectively. During the course of the 1st year of prehospital transfusions, no blood was wasted and there were no adverse effects. CONCLUSION: Introduction of the prehospital packed red blood cell transfusion service was successful, with significant improvement in hemodynamic parameters.

Manejo del trauma pre-hospitalario. ¿Qué hacer?

El manejo pre-hospitalario del trauma corresponde a la fase cero del control de daños, tiene por objetivo evitar y prevenir el desarrollo del rombo mortal. A pesar de que la mortalidad causada por una hemorragia aguda traumática es prevenible, solo el 50% de los pacientes son manejados a tiempo. En la actualidad, existen múltiples métodos mecánicos y químicos para el control hemorrágico en un ambiente austero. La campaña Stop the Bleed de la American College of Surgeons (ACS), ha promovido el uso de los dispositivos mecánicos por la población general a través de la capacitación. En el enfrentamiento prehospitalario del trauma, se utiliza el clásico A-B-C-D-E, agregando la letra X al inicio, para indicar que el primer manejo debe ser el control de las hemorragias externas compresibles. En conclusión: El manejo prehospitalario rápido y ordenado, determina mejores resultados en la evolución clínica y sobrevida del paciente politraumatizado.

The pre-hospital management of trauma is zero phase of damage control, its objective is to avoid and prevent the development of the fatal rhombus. Although mortality caused by acute traumatic hemorrhage is preventable, only 50% of patients are managed on time. Currently there are multiple mechanical and chemical methods for hemorrhagic control in an austere environment. The Stop the Bleed program of the American College of Surgeons (ACS) has promoted the use of mechanical devices by the general population through training. In prehospital trauma, the classic A-B-C-D-E is used, adding the letter X at the beginning to indicate that the first management should be of compressible external hemorrhages. The rapid and orderly prehospital management determines better results in the clinical evolution and survival of the polytraumatized patient.

Direct transport versus inter-hospital transfer of trauma victims in the Brazilian Emergency Medical System.

Introduction: The Brazilian medical emergency services presented a significant development due to the investment in emergency care units, increasing the expansion of the services. However, there was a surge in need for secondary patient transfers, which served as the common link in a wide web of tertiary hospital access. This study aimed to assess the outcome of trauma patients who required secondary transfer. Patients and methods: This prospective observational cross-sectional study included 2302 patients (565 from the study group and 1737 from the control group) and compared the outcome of patients hospitalized for trauma referred by secondary transfer or those who directly visited the Emergency Unit of the municipality with a Brazilian medical emergency system. Results: As for the trauma mechanism, there was a predominance of blunt trauma (93.32 %), 34.5 % were elderly, 12.45 % suffered severe traumatic brain injury, and 18.44 % had severe trauma rate (injury severity score > 15). The outcome of death did not present a significant difference between the groups, even when evaluated considering possible risk factors, such as the elderly age (over 65 years of age) and trauma index. Conclusion: There was no significant difference in terms of the outcome of death in patients who underwent secondary transfer and those with direct access to medical emergency services. However, patients who underwent secondary transfer had an increase in the length of hospital stay.

Lessons from the Fallen: An After-Action Review of Prehospital Casualty Data during the Global War on Terror.

BACKGROUND: The US military's recent involvement in long standing conflict has caused the pioneering of many lifesaving medical advances, often made possible by data-driven research. However, future advances in battlefield medicine will likely require greater data fidelity than is currently attainable. Continuing to improve survival rates will require data which establishes the relative contributions to preventable mortality and guides future interventions. Prehospital data, particularly that from Tactical Combat Casualty Care (TCCC) Cards and TCCC After Action Reports (TCCC AARs), are notoriously inconsistent in reaching searchable databases for formal evaluation. While the military has begun incorporating more modern technology in advanced data capture over the past few years like the Air Force's Battlefield Assisted Trauma Distributed Observation Kit (BATDOK) and the Army's Medical Hands-free Unified Broadcast system (MEDHUB), more analysis weighing the advantages and disadvantages of substituting analog solutions is needed. DISCUSSION: We propose 3 changes which may aid prehospital data capture and facilitate analysis: reexamine the current format of TCCC Cards and consider reducing the number of available datapoints to streamline completion, implement a military-wide mandate for all Role 1 providers to complete a TCCC AAR within 24 hours of a casualty event, and formalize the process of requesting de-identified data from the Armed Forces Medical Examiner System (AFMES) database. CONCLUSION: Reflecting on the state of US military medicine after 20 years of war, an important focus is improving the way prehospital data is gathered and analyzed by the military. There are steps we can take now to enhance our capabilities.

Prehospital Pharmacotherapy in Moderate and Severe Traumatic Brain Injury: A Systematic Review.

BACKGROUND: Traumatic brain injury (TBI) affects civilian and military populations with high morbidity and mortality rates and devastating sequelae. As the US military shifts its operational paradigm to prepare for future large-scale combat operations, the need for prolonged casualty care is expected to intensify. Identifying efficacious prehospital TBI management strategies is therefore vital. Numerous pharmacotherapies are beneficial in the inpatient management of TBI, including beta blockers, calcium channel blockers, statins, and other agents. However, their utility in prehospital management of moderate or severe TBI is not well understood. We performed a systematic review to elucidate agents of potential prehospital benefit in moderate and severe TBI. METHODS: We searched 6 databases from January 2000 through December 2021 without limitations in outcome metrics using a variety of search terms designed to encapsulate all studies pertaining to prehospital TBI management. We identified 2,142 unique articles, which netted 114 studies for full review. Seven studies met stringent inclusion criteria for our aims. RESULTS: Studies meeting inclusion criteria assessed tranexamic acid (TXA) (n=6) and ethanol (n=1). Of the TXA studies, 3 were randomized controlled trials, 2 were retrospective cohort studies, 1 was a prospective cohort study, and 1 was a meta-analysis. Notably absent were papers investigating therapeutics shown to be beneficial in inpatient hospital treatment of TBI. Overall, data suggest TXA administration is potentially beneficial in moderate or severe TBI with or without intracranial hemorrhage. Severe TBI with or without penetrating trauma was associated with worse overall outcomes, regardless of TXA use. CONCLUSION: Effective interventions for treating moderate or severe TBI are lacking. TXA is the most widely studied pharmacologic intervention and appears to offer some benefit without adverse effects in moderate TBI (with or without intracranial hemorrhage) in the pre-hospital setting despite heterogeneous results. Limitations of these studies include heterogeneity in outcome metrics, patient populations, and circumstances of TXA use. We identified a gap in the literature in translating agents with demonstrated inpatient benefit to the prehospital setting. Further investigation into these and other novel therapeutic options in the prehospital arena is crucial to improving clinical outcomes in TBI.
