Valor pronóstico de los parámetros metabólicos medidos en la asistencia inicial a pacientes con trauma grave: asociación con la puntuación de la escala NISS y la mortalidad / Prognostic value of metabolic parameters measured by first responders attending patients with severe trauma: associations with the New Injury Severity Score and mortality

Objetivos. En entornos de emergencia prehospitalarios, la detección temprana de un paciente con trauma grave o potencialmente crítico es un desafío. El objetivo es analizar las posibilidades diagnósticas y pronóstico de los parámetros analíticos obtenidos en los primeros momentos de la asistencia inicial. Métodos. Estudio observacional multicéntrico de la base de datos prospectiva “Código Trauma” de 2016-2019 excluyendo el trauma craneoencefálico aislado. La evaluación de las lesiones se realizó utilizando el New Injury Severity Score (NISS). Los pacientes fueron clasificados en 4 grupos según nivel de gravedad. Para el análisis inferencial, las puntuaciones NISS y el resultado de mortalidad se consideraron variables dependientes. Se realizó el análisis de la curva ROC, puntos de corte óptimos mediante el índice de Youden y se calcularon los valores predictivos positivo (VPP) y negativo. Resultados. De los 1.039 pacientes traumatizados del registro, 709 fueron incluidos en el estudio, con una edad media de 40,4 años (DE 17,3), 77,3% eran varones, el mecanismo lesional principal accidentes de moto (21%) y la mortalidad del 12,1%. El pH, lactato, pCO2, hemoglobina, hematocrito y glucemia influyeron significativamente en gravedad y mortalidad. El VPP de mortalidad para pH fue 61,2, 64,1, 70,7, 62,2 y 66,6 para los grupos de NISS 34-41, 42-49, 50-59 y $ 60 puntos la mortalidad, respectivamente. Las variables clínicas clásicas obtuvieron valores más bajos. Conclusiones. Los pacientes con mayor gravedad presentaron menor pH y concentraciones más altas de pCO2, lactato y exceso de bases. El pH, la pCO2 y la glucemia tuvieron la mayor capacidad predictiva de gravedad. La capacidad predictiva de los valores metabólicos es superior a la de los valores hemodinámicos clásicos. (AU)

Background and objective: Patients with severe or potentially severe trauma must be identified early, a challenge in prehospital settings. This study aimed to analyze the possible diagnostic and prognostic usefulness of analytical markers recorded in the early moments of care. Methods: Observational study of information extracted from the prospective multicenter Code Trauma database for 2016-2019, excluding data for isolated head injuries. Using the New Injury Severity Score (NISS), we classified cases into 4 levels of severity. NISS and mortality were considered the dependent variables in inferential analyses. We calculated the areas under receiver operating characteristic curves, identified optimal cutoff points (Youden index), and calculated positive (PPV) and negative predictive values. Results: Of the 1039 trauma patients in the registry, 709 were included in the study. Their mean (SD) age was 40.4 (17.3) years, and 77.3% were men. Motorcycle accidents were the most common causes of trauma (in 21%), and mortality was 12.1%. Lactate concentration, pH, PCO2, hemoglobin concentration, hematocrit, and blood sugar were significantly associated with severity and mortality. The PPVs corresponding to pH for the 4 NISS score groups (34-41, 42-49, 50-59, and $ 60) and mortality, respectively, were 61.2, 64.1, 70.7, 62.2, and 66.6. The PPVs of traditionally used clinical variables were lower. Conclusions: Patients with more severe trauma had lower pH values and higher PCO2, lactate, and base excess values. PCO2, pH, and blood sugar findings were the best predictors of severity. Metabolic variables are better predictors than traditionally recorded hemodynamic variables. (AU)

Visión general y comparación de la presencia de médicos en los servicios de emergencias médicas prehospitalarios en Europa / Physician utilization in prehospital emergency medical services in Europe: an overview and comparison

Antecedentes: Los sistemas nacionales y regionales de prestación de atención médica a las emergencias pueden diferir mucho entre sí. Se buscó dilucidar la presencia de médicos en la atención prehospitalaria y su implantación en los diferentes países europeos. Métodos: Se analizaron los datos de 32 países europeos recogidos mediante la revisión de artículos publicados y a través de cuestionarios enviados a los autores de artículos científicos pertinentes, funcionarios del ministerio de sanidad (o equivalente), representantes de sociedades nacionales de medicina de urgencias o expertos reconocidos en medicina de urgencias. Resultados: Treinta de los 32 países europeos investigados (94%) disponen de médicos en los servicios de emergencias prehospitalarios. En 17 de 32 (53%), los médicos generalistas también participan en la atención a las emergencias prehospitalarias. Los modelos de los sistemas de emergencias médicas (SEM) se describieron como francoalemanes en 27 países (84%), híbridos en 17 (53%) o angloamericanos en 14 (44%). En 17 países (53%), coexistían diferentes modelos. Utilizando una nueva forma de clasificación por niveles, basada en la población media y el área atendida por el SEM prehospitalario, se pudieron diferenciar claramente los diferentes modelos existentes. Conclusiones: Se observan notables diferencias en los diseños de los SEM y en la presencia de los médicos entre las diferentes áreas geográficas, países y regiones de Europa. Coexisten varios modelos (francoalemán, híbrido y angloamericano), algunos simultáneamente, en los diferentes países. (AU)

Background: National and regional systems for emergency medical care provision may differ greatly. We sought to determine whether or not physicians are utilized in prehospital care and to what extent they are present in different European countries. Methods: We collected information on 32 European countries by reviewing publications and sending questionnairesto authors of relevant articles as well as to officials of ministries of health (or equivalent), representatives of national societies in emergency medicine, or well-known experts in the specialty. Results: Thirty of the 32 of European countries we studied (94%) employ physicians in prehospital emergency medical services. In 17 of the 32 (53%), general practitioners also participate in prehospital emergency care. Emergency system models were described as Franco-German in 27 countries (84%), as hybrid in 17 (53%), and as Anglo-American in 14(44%). Multiple models were present simultaneously in 17 countries (53%). We were able to differentiate between national prehospital emergency systems with a novel classification based on tiers reflecting the degree of physician utilization in the countries. We also grouped the national systems by average population and area served. Conclusions: There are notable differences in system designs and intensity of physician utilization between different geographic areas, countries, and regions in Europe. Several archetypal models (Franco-German, hybrid, and AngloAmerican) exist simultaneously across Europe. (AU)

Detección en urgencias de infección por VIH en pacientes que consultan por condiciones potencialmente relacionadas con infección oculta: Resultados iniciales del programa “Urgències VIHgila” / Emergency detection of HIV infection in patients consulting for conditions potentially related to occult infection: Initial results of the “Urgències VIHgila” program

Objective: To estimate the prevalence of unknown HIV infection in patients who consulted in hospital emergency services (ED) for conditions defined in the SEMES-GESIDA Consensus Document (DC), evaluate the efficiency of its im-plementation and investigate the efficiency of HIV serology determination in other conditions. Methods: Results were reviewed in 10 Catalan EDs for 12 months (July-21-June-22) after implementing CD recommendations: request HIV serology in case of suspected sexually transmitted infection, chemsex, post-exposure prophylaxis (PEP), mononucleosis syndrome, community pneumonia (18-65 y-o) or herpes zoster (18-65 y-o). Other reasons for request were included. Prevalence (%) of global seropositivity and for each circumstance was calculated, with a 95% confidence interval (95%CI). The efficient strategy was considered if the lower limit of the CI95%>0.1%. Results: A total of5,107 HIV serologies were performed: 2,847(56%) in situations specified in CD, and 2,266 (44%) in other 138 circumstances. Forty-eight unknown HIV infections were detected (prevalence=0.94%;95%CI=0.69-1.24). The prevalence was somewhat higher in DC requests (30 cas-es 1.12%) than the rest (18 cases 0.71%; p=0.16). The individualized prevalence of CD reasons ranged between 7.41% (95%CI=0.91-24.3) in chemsex and 0.42% 95%CI=0.14-0.98) in PPE, always efficient except herpes zoster (0.76%; CI95%=0.02-4.18). In other reasons, cases were detected in 12 circumstances, and in four the determination could be efficient: lymphopenia (10%;CI95%=0.25-44.5), fever with polyarthralgia-polyarthritis (7.41%;CI95% =0.91-24.3), behavioral alteration-confusion-encephalopathy (3.45%;95%CI=0.42-11.9) and fever of unknown origin (2.50%;95%CI=0.82-5.74). (AU)

Objetivo: Estimar la prevalencia de infección por VIH des-conocida en pacientes que consultan en servicios de urgencias hospitalarios (SUH) por las condiciones definidas en el Documento de Consenso (DC) de SEMES-GESIDA, evaluar la eficiencia de su implementación e investigar si en otras condiciones la determinación de serología VIH puede resultar eficiente.Método: Se revisaron los resultados obtenidos en 10 SUH catalanes durante los 12 meses (julio-21 a junio-22) siguientes a implementar las recomendaciones del DC de solicitar serología VIH a pacientes con sospecha de infección de transmisión sexual, práctica de chemsex, solicitud profilaxis post-exposición (PPE), síndrome mononucleósico, neumonía comunitaria (18-65 años) o herpes zóster (18-65 años). Se consignaron también otros motivos de solicitud. Se calculó la prevalencia (%) de seropositividad global y para cada circunstancia, con su intervalo de confianza del 95% (IC95%). Se consideró la estrategia eficiente si el límite inferior del IC95% era >0,1%.Resultados: Se realizaron 5.107 serologías VIH: 2.847 (56%) en situaciones especificadas en el DC, y 2.266 (44%) en otras 138 circunstancias. Se detectaron 48 infecciones por VIH desconocidas (prevalencia=0,94%; IC95%=0,69-1,24). La preva-lencia fue algo superior en las solicitudes ajustadas al DC (30 ca-sos, 1,12%) que en las que no (18 casos, 0,71%; p=0,16). La prevalencia individualizada para los motivos especificados en el DC osciló entre 7,41% IC95%=0,91-24,3) en práctica de chemsex y 0,42% (IC95%=0,14-0,98) en PPE, y siempre resultó eficiente, con excepción de herpes zóster (0,76%, IC95%=0,02-4,18). Respecto al resto de motivos de solicitud, se detectaron casos en 12 circunstancias, y en cuatro la determinación podría ser eficiente: linfopenia (10%, IC95%=0,25-44,5), fiebre con poliartralgias-poliartritis (7,41%, IC95%=0,91-24,3), alteración conductual-confusión-encefalopatía (3,45%,IC95%=0,42-11,9) y fiebre de origen desconocido(2,50%,IC95%=0,82-5,74)(AU)

[Public guide for "first aid onsite-first responders action" in China (2023)].

In order to improve the popularity of first aid knowledge among the public, First Aid Professional Committee of China Geriatric Health Care Association has formulated the Public guide for "first aid onsite-first responders action" in China (2023). This guide aims at providing with the first eyewitness action guide that are critical but weak onsite rescue link of Chinese emergency medical service system to the public. In the first scene of injury and illness emergencies, it is very important for the first eyewitness to make a prompt and correct response in the first time. Based on best practice evidence, this guide combs the core concepts of onsite first aid in order to provide guidance and help in standardizing the popularization of public first aid knowledge and skills.

Engaging emergency medical services to improve postacute management of behavioural health emergency calls: a protocol of a scoping literature review.

INTRODUCTION: The public health crisis of escalating mental health, behavioural and substance-related emergencies has revealed the need to approach these complex events from a health perspective, rather than the traditional criminal justice standpoint. Despite law enforcement officers often being the first responders to emergency calls concerning self or bystander harm, they are not optimally equipped to manage these crises holistically or to connect affected individuals to necessary medical treatment and social support. Paramedics and other emergency medical services (EMS) providers are well positioned to deliver comprehensive medicosocial care during and in the immediate aftermath of these emergencies, moving beyond their traditional role in emergency evaluation, stabilisation and transport to a higher level of care. The role of EMS in bridging this gap and helping shift emphasis to mental and physical health needs in crisis situations has not been examined in prior reviews. METHODS AND ANALYSIS: In this protocol, we delineate our approach to describing existing EMS programmes that focus specifically on supporting individuals and communities experiencing mental, behavioural and substance-related health crises. The databases to be searched are EBSCO CINAHL, Ovid Cochrane Central Register of Controlled Trials, Ovid Embase, Ovid Medline, Ovid PsycINFO and Web of Science Core Collection, with search date limits being from database inception to 14 July 2022. A narrative synthesis will be completed to characterise populations and situations targeted by the programmes, describe programme staffing and composition, detail the interventions and identify collected outcomes. ETHICS AND DISSEMINATION: All data in the review will be publicly accessible and published previously, so approval by a research ethics board is not needed. Our findings will be published in a peer-reviewed journal and shared with the public. TRIAL REGISTRATION NUMBER: https://doi.org/10.17605/OSF.IO/UYV4R.

Prehospital clinical practice guidelines for unintentional injuries: a scoping review and prioritisation process.

BACKGROUND: Globally, millions of people die and many more develop disabilities resulting from injuries each year. Most people who die from injuries do so before they are transported to hospital. Thus, reliable, pragmatic, and evidence-based prehospital guidance for various injuries is essential. We systematically mapped and described prehospital clinical practice guidelines (CPGs) for injuries in the global context, as well as prioritised injury topics for guidance development and adolopment. METHODS: This study was sequentially conducted in three phases: a scoping review for CPGs (Phase I), identification and refinement of gaps in CPGs (Phase II), and ranking and prioritisation of gaps in CPGs (Phase III). For Phase I, we searched PubMed, SCOPUS, and Trip Database; guideline repositories and websites up to 23rd May 2021. Two authors in duplicate independently screened titles and abstract, and full-text as well as extracted data of eligible CPGs. Guidelines had to meet 60% minimum methodological quality according to rigour of development domain in AGREE II. The second and third phases involved 17 participants from 9 African countries and 1 from Europe who participated in a virtual stakeholder engagement workshop held on 5 April 2022, and followed by an online ranking process. RESULTS: Fifty-eight CPGs were included out of 3,427 guidance documents obtained and screened. 39/58 (67%) were developed de novo compared to 19 that were developed using alternative approaches. Twenty-five out of 58 guidelines (43%) were developed by bodies in countries within the WHO European Region, while only one guideline was targeted to the African context. Twenty-five (43%) CPGs targeted emergency medical service providers, while 13 (22%) targeted first aid providers (laypeople). Forty-three CPGs (74%) targeted people of all ages. The 58 guidance documents contained 32 injury topics. Injuries linked to road traffic accidents such as traumatic brain injuries and chest injuries were among the top prioritised topics for future guideline development by the workshop participants. CONCLUSION: This study highlights the availability, gaps and priority injury topics for future guideline development/adolopment, especially for the African context. Further research is needed to evaluate the recommendations in the 58 included CPGs for possible adaptation to the African context.

Digital feedback during clinical education in the emergency medical services: a qualitative study.

BACKGROUND: Clinical education is essential for students' progress towards becoming registered nurses (RN) in Sweden. Assessment of caring skills in the Emergency Medical Services (EMS) is complex due to the ever-changing scenarios and the fact that multiple supervisors are involved in the student's education. Currently, assessments of student's skills are summative and occur twice during the six weeks of clinical education. A digitalized assessment tool (DAT) with an adaptation for formative assessment is a new approach to assessment of nursing skills in the EMS. Since new technologies and changes in procedures are likely to affect both students and supervisors, our aim in this study is to describe students' and clinical supervisors' experience of formative assessments using DAT in the EMS. METHOD: This study is qualitative, using semi-structured group interviews (N = 2) with students and semi-structured individual telephone interviews (N = 13) with supervisors. The data was analysed according to Graneheim and Landman's method for content analysis. This analysis generated 221 codes organized into 10 categories within which three themes were identified. The students in this study were nursing students in their last semester and all supervisors were experienced RNs. RESULTS: The results showed that students and supervisors had mainly positive views of the DAT and the formative assessment stating that the information they provided while using the DAT offered opportunities for reflection. The DAT supported the students' learning by visualizing strengths and areas of improvement, as well as displaying progress using a Likert scale. The application improved communication, but additional features linking the assessment tool with the university were requested. The application contributed to transparency in the assessments and was seen as preferable to the traditional 'pen and paper' method. CONCLUSION: A digital system was described in a positive manner, and the assessment using the DAT facilitated reflection and formative assessment. The use of a Likert scale was considered positive in order to demonstrate progression which with advantage could be demonstrated visually.

The Role of Activated Charcoal in Prehospital Care.

Background: Administration of a single-dose activated charcoal (SDAC) is an effective method used for gastric decontamination and for other types of poisoning and overdose. This is only true when given within the first hour of poison ingestion as the effectivity of SDAC reduces over time. In addition, generally, not all patients are able to avail treatment within the specified period. Hence, multi-dose activated charcoal is regarded as a solution to a delayed process, although, no proof outweighs the use of SDAC. Objective: This study aimed to review and assess the adequacy of the past and current use of AC. The author also aimed to offer recommendations believed to be the best method to consider for prehospital care. Methods: The author conducted 6,337 online literature searches for this review, wherein seven papers met eligibility criteria for inclusion and analysis. Results: In this review, routine administration of AC in poisoning was found not related to the duration of hospital stay nor any other subsequent outcomes following poison ingestion. Further, this review did not establish that administration of AC could improve patient's clinical outcome. Further research and clinical trials is required to determine the efficacy of this therapy to appropriate patients in the prehospital setting. Conclusion: Activated charcoal can be used to treat highly acute to life-threatening poisoning if it is administered within the first hour of ingestion. Further studies would be necessary to investigate if this would affect clinical outcome..

Impact of Coronavirus Disease 2019 Pandemic on Cardiac Arrest and Emergency Care.

The incidence of both out-of-hospital and in-hospital cardiac arrest increased during the coronavirus disease 2019 (COVID-19) pandemic. Patient survival and neurologic outcome after both out-of-hospital and in-hospital cardiac arrest were reduced. Direct effects of the COVID-19 illness combined with indirect effects of the pandemic on patient's behavior and health care systems contributed to these changes. Understanding the potential factors offers the opportunity to improve future response and save lives.

Cost consequences of unscheduled emergency admissions in cancer patients in the last year of life.

OBJECTIVES: Cancer is a leading cause of death. This paper examines the utilisation of unscheduled emergency end-of-life healthcare and estimates expenditure in this domain. We explore care patterns and quantify the likely benefits from service reconfigurations which may influence rates of hospital admission and deaths. METHODS: Using prevalence-based retrospective data from the Northern Ireland General Registrar's Office linked by cancer diagnosis to Patient Administration episode data for unscheduled emergency care (1st January 2014 to 31st December 2015), we estimate unscheduled-emergency-care costs in the last year of life. We model potential resources released by reductions in length-of-stay for cancer patients. Linear regression examined patient characteristics affecting length of stay. RESULTS: A total of 3134 cancer patients used 60,746 days of unscheduled emergency care (average 19.5 days). Of these, 48.9% had ≥1 admission during their last 28 days of life. Total estimated cost was £28,684,261, averaging £9200 per person. Lung cancer patients had the highest proportion of admissions (23.2%, mean length of stay = 17.9 days, mean cost=£7224). The highest service use and total cost was in those diagnosed at stage IV (38.4%), who required 22,099 days of care, costing £9,629,014. Palliative care support, identified in 25.5% of patients, contributed £1,322,328. A 3-day reduction in the mean length of stay with a 10% reduction in admissions, could reduce costs by £7.37 million. Regression analyses explained 41% of length-of-stay variability. CONCLUSIONS: The cost burden from unscheduled care use in the last year of life of cancer patients is significant. Opportunities to prioritise service reconfiguration for high-costing users emphasized lung and colorectal cancers as offering the greatest potential to influence outcomes.

The impact of COVID-19 pandemic on obstetrics and gynecology hospitalization rate and on reasons for seeking emergency care: a systematic review and meta-analysis.

BACKGROUND: During the lockdown due to COVID-19 pandemic, utilization of emergency care units has been reported to be reduced for obstetrical and gynaecological reasons. The aim of this systematic review is to assess if this phenomenon reduced the rate of hospitalizations for any reason and to evaluate the main reasons for seeking care in this subset of the population. METHODS: The search was conducted using the main electronic databases from January 2020 to May 2021. The studies were identified with the use of a combination of: "emergency department" OR "A&E" OR "emergency service" OR "emergency unit" OR "maternity service" AND "COVID-19" OR "COVID-19 pandemic" OR "SARS-COV-2" and "admission" OR "hospitalization". All the studies that evaluated women going to obstetrics & gynecology emergency department (ED) during the COVID-19 pandemic for any reason were included. RESULTS: The pooled proportion (PP) of hospitalizations increased from 22.7 to 30.6% during the lockdown periods, in particular from 48.0 to 53.9% for delivery. The PP of pregnant women suffering from hypertensive disorders increased (2.6 vs 1.2%), as well as women having contractions (52 vs 43%) and rupture of membranes (12.0 vs 9.1%). Oppositely, the PP of women having pelvic pain (12.4 vs 14.4%), suspected ectopic pregnancy (1.8 vs 2.0), reduced fetal movements (3.0 vs 3.3%), vaginal bleeding both for obstetrical (11.7 vs 12.8%) and gynecological issues (7.4 vs 9.2%) slightly reduced. CONCLUSION: During the lockdown, an increase in the proportion of hospitalizations for obstetrical and gynecological reasons has been registered, especially for labor symptoms and hypertensive disorders.

Second Victims among German Emergency Medical Services Physicians (SeViD-III-Study).

BACKGROUND: Patient care in the prehospital emergency setting is error-prone. Wu's publications on the second victim syndrome made very clear that medical errors may lead to severe emotional injury on the caregiver's part. So far, little is known about the extent of the problem within the field of prehospital emergency care. Our study aimed at identifying the prevalence of the Second Victim Phenomenon among Emergency Medical Services (EMS) physicians in Germany. METHODS: Web-based distribution of the SeViD questionnaire among n = 12.000 members of the German Prehospital Emergency Physician Association (BAND) to assess general experience, symptoms and support strategies associated with the Second Victim Phenomenon. RESULTS: In total, 401 participants fully completed the survey, 69.1% were male and the majority (91.2%) were board-certified in prehospital emergency medicine. The median length of experience in this field of medicine was 11 years. Out of 401 participants, 213 (53.1%) had experienced at least one second victim incident. Self-perceived time to full recovery was up to one month according to 57.7% (123) and more than one month to 31.0% (66) of the participants. A total of 11.3% (24) had not fully recovered by the time of the survey. Overall, 12-month prevalence was 13.7% (55/401). The COVID-19 pandemic had little effect on SVP prevalence within this specific sample. CONCLUSIONS: Our data indicate that the Second Victim Phenomenon is very frequent among prehospital emergency physicians in Germany. However, four out of ten caregivers affected did not seek or receive any assistance in coping with this stressful situation. One out of nine respondents had not yet fully recovered by the time of the survey. Effective support networks, e.g., easy access to psychological and legal counseling as well as the opportunity to discuss ethical issues, are urgently required in order to prevent employees from further harm, to keep healthcare professionals from leaving this field of medical care and to maintain a high level of system safety and well-being of subsequent patients.

Efficacy of intraosseous access for trauma resuscitation: a systematic review and meta-analysis.

BACKGROUND: During medical emergencies, intraosseous (IO) access and intravenous (IV) access are methods of administering therapies and medications to patients. Treating patients in emergency medical situations is a highly time sensitive practice; however, research into the optimal access method is limited and existing systematic reviews have only considered out-of-hospital cardiac arrest (OHCA) patients. We focused on severe trauma patients and conducted a systematic review to evaluate the efficacy and efficiency of intraosseous (IO) access compared to intravenous (IV) access for trauma resuscitation in prehospital care. MATERIALS AND METHOD: PubMed, Web of Science, Cochrane Library, EMBASE, ScienceDirect, banque de données en santé publique and CNKI databases were searched for articles published between January 1, 2000, and January 31, 2023. Adult trauma patients were included, regardless of race, nationality, and region. OHCA patients and other types of patients were excluded. The experimental and control groups received IO and IV access, respectively, in the pre-hospital and emergency departments for salvage. The primary outcome was success rate on first attempt, which was defined as secure needle position in the marrow cavity or a peripheral vein, with normal fluid flow. Secondary outcomes included mean time to resuscitation, mean procedure time, and complications. RESULTS: Three reviewers independently screened the literature, extracted the data, and assessed the risk of bias in the included studies; meta-analyses were then performed using Review Manager (Version 5.4; Cochrane, Oxford, UK). The success rate on first attempt was significant higher for IO access than for IV access (RR = 1.46, 95% CI [1.16, 1.85], P = 0.001). The mean procedure time was significantly reduced (MD = - 5.67, 95% CI [- 9.26, - 2.07], P = 0.002). There was no significant difference in mean time to resuscitation (MD = - 1.00, 95% CI [- 3.18, 1.17], P = 0.37) and complications (RR = 1.22, 95% CI [0.14, 10.62], P = 0.86) between the IO and IV groups. CONCLUSION: The success rate on first attempt of IO access was much higher than that of IV access for trauma patients, and the mean procedure time of IO access was significantly less when compared to IV access. Therefore, IO access should be suggested as an urgent vascular access for hypotensive trauma patients, especially those who are under severe shock.

Emergency medical services and palliative care: a scoping review.

OBJECTIVES: The aim of this study was to map existing emergency medical services (EMS) and palliative care literature by answering the question, what literature exists concerning EMS and palliative care? The sub-questions regarding this literature were, (1) what types of literature exist?, (2) what are the key findings? and (3) what knowledge gaps are present? DESIGN: A scoping review of literature was performed with an a priori search strategy. DATA SOURCES: MEDLINE via Pubmed, Web of Science, CINAHL, Embase via Scopus, PsycINFO, the University of Cape Town Thesis Repository and Google Scholar were searched. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Empirical, English studies involving human populations published between 1 January 2000 and 24 November 2022 concerning EMS and palliative care were included. DATA EXTRACTION AND SYNTHESIS: Two independent reviewers screened titles, abstracts and full texts for inclusion. Extracted data underwent descriptive content analysis and were reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews guidelines. RESULTS: In total, 10 725 articles were identified. Following title and abstract screening, 10 634 studies were excluded. A further 35 studies were excluded on full-text screening. The remaining 56 articles were included for review. Four predominant domains arose from included studies: (1) EMS' palliative care role, (2) challenges faced by EMS in palliative situations, (3) EMS and palliative care integration benefits and (4) proposed recommendations for EMS and palliative care integration. CONCLUSION: EMS have a role to play in out-of-hospital palliative care, however, many challenges must be overcome. EMS provider education, collaboration between EMS and palliative systems, creation of EMS palliative care guidelines/protocols, creation of specialised out-of-hospital palliative care teams and further research have been recommended as solutions. Future research should focus on the prioritisation, implementation and effectiveness of these solutions in various contexts.

Efficacy of Fascia Iliaca Compartment Blocks in Proximal Femoral Fractures in the Prehospital Setting: A Systematic Review and Meta-Analysis.

INTRODUCTION: Proximal femoral fractures are characterized as one of the most common and most painful injuries sustained by patients of all ages and are associated with high rates of oligoanalgesia in the prehospital setting. Current treatments include oral and parenteral opiates and sedative agents, however regional anesthesia techniques for pain relief may provide superior analgesia with lower risk of side effects during patient transportation. The fascia iliaca compartment block (FICB) is an inexpensive treatment which is performed with minimal additional equipment, ultimately making it suitable in prehospital settings. PROBLEM: In adult patients sustaining proximal femoral fractures in the prehospital setting, what is the effect of the FICB on non-verbal pain scores (NVPS), patient satisfaction, success rate, and adverse events compared to traditional analgesic techniques? METHODS: A librarian-assisted literature search was conducted of the Cochrane Database, Ovid MEDLINE, PubMed, Ovid EMBASE, Scopus, and Web of Science indexes. Additionally, reference lists for potential review articles from the British Journal of Anesthesia, the College of Anesthetists of Ireland, the Journal of Prehospital Emergency Care, Annales Francaises d'Anesthesie et Réanimation, and the Scandinavian Journal of Trauma, Resuscitation, and Emergency Medicine were reviewed. Databases and journals were searched during the period from January 1, 1980 through July 1, 2022. Each study was scrutinized for quality and validity and was assigned a level of evidence as per Oxford Center for Evidence-Based Medicine guidelines. RESULTS: Five studies involving 340 patients were included (ie, two randomized control trials [RCTs], two observational studies, and one prospective observational study). Pain scores decreased after prehospital FICB across all included studies by a mean of 6.65 points (5.25 - 7.5) on the NVPS. Out of the total 257 FICBs conducted, there was a success rate of 230 (89.3%). Of these, only two serious adverse events were recorded, both of which related to local analgesia toxicity. Neither resulted in long-term sequelae and only one required treatment. CONCLUSION: Use of FICBs results in a significant decrease in NVPS in the prehospital setting, and they are ultimately suitable as regional analgesic techniques for proximal femur fractures. It carries a low risk of adverse events and may be performed by health care practitioners of various backgrounds with suitable training. The results suggest that FICBs are more effective for pain management than parenteral or oral opiates and sedative agents alone and can be used as an appropriate adjunct to pain management.

Piloting a Layperson Prehospital Care System in Rural Uganda.

INTRODUCTION: In many low-income countries, basic prehospital Emergency Medical Services (EMS) remain under-developed, resulting in significant delays or the complete inability to access care. STUDY OBJECTIVE: The purpose of this study was to analyze the effectiveness of a layperson EMS training targeting motorcycle taxi (boda) drivers in a rural region of Uganda. METHODS: Fifty (50) adult boda drivers from Masindi, Uganda were selected for a one-day training course including lectures and simulation. Course content covered basic prehospital skills and transport. Participants were given a first responder kit at completion of the course. Understanding of material was assessed prior to training, immediately after course completion, and four months from the initial course using the same ten question test. Test means were analyzed using a standard linear regression model. At the four-month follow up, all 50 boda drivers participated in semi-structured small group qualitative interviews regarding their perception of the course and experiences implementing course skills in the community. Boda drivers were asked to complete a brief form on each patient transported during the study period. For patients transported to Masindi Kitara Medical Center (MKMC), hospital trauma registry data were analyzed. RESULTS: Trainees showed both knowledge acquisition and retention with pre-test scores of 21.8% improving to 48.0% at course completion and 57.7% at the four-month follow up. Overall, participant's scores increased by an average of 35% from the pre-test to the second post-test (P <.001). A total of 69 patient forms were completed on transported patients over the initial four-month period. Ninety-five percent (95%) of these were injured patients, and motorcycle crash was the predominant mechanism of injury (48% of injuries). Eight patients were transported to MKMC, but none of these patients were recorded in the hospital trauma registry. Major barriers identified through semi-structured interviews included harassment by police, poor road conditions, and lack of basic resources for transport. Ninety-four percent (94%) of trainees strongly agreed that the training was useful. Total costs were estimated at $3,489 USD, or $69 per trainee. CONCLUSION: Motorcycle taxi drivers can be trained to provide basic prehospital care in a short time and at a low cost. While there is much enthusiasm for additional training and skill acquisition from this cohort, the sustainability and scalability of such programs is still in question.

The Safety, Efficacy, and Expediency of Albuterol Nebulizer Administration by BLS Providers.

INTRODUCTION: Many Emergency Medical Service (EMS) systems in the United States restrict albuterol therapy by scope of practice to Advanced Life Support (ALS). The State of Delaware has a two-tiered EMS system in which Basic Life Support (BLS) arrives on scene prior to ALS in the majority of respiratory distress calls. STUDY OBJECTIVE: This study sought to evaluate the safety, efficacy, and expedience of albuterol administration by BLS compared to ALS. METHODS: This retrospective observational study used data collected from July 2015 through January 2017 throughout a State BLS albuterol pilot program. Pilot BLS agencies participated in a training session on the indications and administration of albuterol, and were then authorized to carry and administer nebulized albuterol. Heart rate (HR), respiratory rate (RR), and pulse oximetry (spO2) were obtained before and after albuterol administration by BLS and ALS. The times from BLS arrival to the administration of albuterol by pilot BLS agencies versus ALS were compared. Study encounters required both BLS and ALS response. Data were analyzed using chi-square and t-test as appropriate. RESULTS: Three hundred eighty-eight (388) incidents were reviewed. One hundred eighty-five (185) patients received albuterol by BLS pilot agencies and 203 patients received albuterol by ALS. Of note, the population treated by ALS was significantly older than the population treated by BLS (61.9 versus 51.6 years; P <.001). A comparison of BLS arrival time to albuterol administration time showed significantly shorter times in the BLS pilot group compared to the ALS group (3.50 minutes versus 8.00 minutes, respectively; P <.001). After albuterol administration, BLS pilot patients showed improvements in HR (P <.01), RR (P <.01), and spO2 (P <.01). Alternately, ALS treatment patients showed improvement in spO2 (P <.01) but not RR (P = .17) or HR (P = 1.00). Review by ALS or hospital staff showed albuterol was indicated in 179 of 185 BLS patients and administered correctly in 100% of these patients. CONCLUSION: Patients both received albuterol significantly sooner and showed superior improvements in vital signs when treated by BLS agencies carrying albuterol rather than by BLS agencies who required ALS arrival for albuterol. Two-tiered EMS systems should consider allowing BLS to carry and administer albuterol for safe, effective, and expedient treatment of respiratory distress patients amenable to albuterol therapy.
