pre hospital emergency medicine

IMPORTANCE: The introduction of large language models (LLMs), such as Generative Pre-trained Transformer 4 (GPT-4; OpenAI), has generated significant interest in health care, yet studies evaluating their performance in a clinical setting are lacking. Determination of clinical acuity, a measure of a patient's illness severity and level of required medical attention, is one of the foundational elements of medical reasoning in emergency medicine. OBJECTIVE: To determine whether an LLM can accurately assess clinical acuity in the emergency department (ED)...

BACKGROUND: Despite continuous advances in post-resuscitation management, outcome after out-of-hospital cardiac arrest (OHCA) is limited. To improve the outcome, interdisciplinary Cardiac Arrest Centers (CACs) have been established in recent years, but survival remains low and treatment strategies vary considerably in clinical and geographical aspects. Here we analyzed a strategy of in-hospital post-resuscitation management while evaluating the outcome. METHODS: A broad spectrum of pre- and in-hospital parameters of 545 resuscitated patients, admitted to the Cardiac Arrest Center of the University Hospital of Marburg (MCAC) between 01/2018 and 12/2022 were retrospectively analyzed...

BACKGROUND: The global evolution of pre-hospital care systems faces dynamic challenges, particularly in multinational settings. Machine learning (ML) techniques enable the exploration of deeply embedded data patterns for improved patient care and resource optimisation. This study's objective was to accurately predict cases that necessitated transportation versus those that did not, using ML techniques, thereby facilitating efficient resource allocation. METHODS: ML algorithms were utilised to predict patient transport decisions in a Middle Eastern national pre-hospital emergency medical care provider...

INTRODUCTION: Prehospital stroke endovascular therapy bypass transports patients with suspected large vessel occlusion directly to an endovascular therapy capable center. Our objective was to determine if an endovascular therapy bypass protocol improved access to stroke treatments. Secondary objectives were to determine safety, effectiveness, and rate of subsequent interfacility transfers. METHODS: Endovascular therapy bypass in 2018 was implemented in Eastern Ontario, for patients with a Los-Angeles-Motor-Scale ≥ 4 (positive large vessel occlusion screen) with a 90-min transport time if < 6 h from last seen well...

BACKGROUND: There are concerns that airway management in patients with suspected or confirmed cervical spine injury may exacerbate an existing neurological deficit, cause a new spinal cord injury or be hazardous due to precautions to avoid neurological injury. However, there are no evidence-based guidelines for practicing clinicians to support safe and effective airway management in this setting. METHODS: An expert multidisciplinary, multi-society working party conducted a systematic review of contemporary literature (January 2012-June 2022), followed by a three-round Delphi process to produce guidelines to improve airway management for patients with suspected or confirmed cervical spine injury...

INTRODUCTION: The purpose of this study is to evaluate the patient selection methods, treatment outcomes, complications, clinical and radiological follow-up after renal angiomyolipoma (AML) treatment with selective arterial embolization (SAE) in an Australian metropolitan tertiary centre. METHODS: This study presents a retrospective single-centre review of patients' medical records who underwent SAE for renal AML during the period of 1st January 2012 and 1st January 2023...

The fee-for-service funding model for US emergency department (ED) clinician groups is increasingly fragile. Traditional fee-for-service payment systems offer no financial incentives to improve quality, address population health, or make value-based clinical decisions. Fee-for-service also does not support maintaining ED capacity to handle peak demand periods. In fee-for-service, clinicians rely heavily on cross-subsidization, where high reimbursement from commercial payors offsets low reimbursement from government payors and the uninsured...

SETTING: Royal Prince Alfred Hospital, a quaternary referral hospital in Sydney...

OBJECTIVE: This study aimed to investigate the incidence and pattern of tramadol-induced seizures and injuries in patients admitted to the hospital. METHODS: The cross-sectional study included 300 patients with alleged tramadol intoxication. Demographic information, tramadol dosage and duration of abuse, co-existing illicit drug abuse, hospital stay length, and occurrence of seizures and trauma (type and site of injuries) were collected. Different statistical tests, including the Mann-Whitney U-test, Pearson's Chi-square test, and Student's t-test, were conducted to compare the patients with and without seizures, trauma, and co-ingestion of illicit drugs...

BACKGROUND: Although frailty is one of the aging syndromes, it can occur at a younger age and in individuals with organ diseases. Identifying frailty and pre-frailty in patients with chronic respiratory diseases (CRDs) is an emerging assessment in the field of pulmonary medicine and rehabilitation. The aim of this study was to find out the prevalence of frailty among chronic respiratory disease patients. METHODS: A single centre cross-sectional survey study with a total population of 381 patients, adults aged 18-90 years presenting to the pulmonology OPD was included based on the inclusion and exclusion criteria...

BACKGROUND: Efficient resource distribution is important. Despite extensive research on response timings within ambulance services, nuances of time from unit dispatch to becoming available still need to be explored. This study aimed to identify the determinants of the duration between ambulance dispatch and readiness to respond to the next case according to the patients' transport decisions. METHODS: Time from ambulance dispatch to availability (TDA) analysis according to the patients' transport decision (Transport versus Non-Transport) was conducted using R-Studio™ for a data set of 93,712 emergency calls managed by a Middle Eastern ambulance service from January to May 2023...

OBJECTIVES: Ever since COVID-19, short-term changes in transport injury patterns have been observed. The aim is to examine both the initial and the enduring impact of government lockdown and the pandemic on road injuries requiring hospitalisation and road fatalities. METHODS: Time series analysis of Transport Accident Commission (TAC) claims involving hospitalisation and fatalities in Victoria, Australia, from July 2016 to May 2023, including lockdown (March 2020 to October 2020) and post-lockdown (November 2020 onwards)...

OBJECTIVE: Hemodynamic collapse in multi-trauma patients with severe traumatic brain injury (TBI) poses both a diagnostic and therapeutic challenge for prehospital clinicians. Brain injury associated shock (BIAS), likely resulting from catecholamine storm, can cause both ventricular dysfunction and vasoplegia but may present clinically in a manner similar to hemorrhagic shock. Despite different treatment strategies, few studies exist describing this phenomenon in the early post-injury phase...

Dragon's blood (DB) is a traditional Chinese medicine (TCM) with hemostatic effects and antibacterial properties. However, it is still challenging to use for rapid hemostasis because of its insolubility. In this study, different amounts of DB were loaded on mesoporous silica nanoparticles (MSNs) to prepare a series of DB-MSN composites (5DB-MSN, 10DB-MSN, and 20DB-MSN). DB-MSN could quickly release DB and activate the intrinsic blood coagulation cascade simultaneously by DB and MSN. Hemostasis tests demonstrated that DB-MSN showed superior hemostatic effects than either DB or MSNs alone, and 10DB-MSN exhibited the best hemostatic effect...

BACKGROUND: Hospitalization presents an opportunity to begin people with opioid use disorder (OUD) on medications for opioid use disorder (MOUD) and link them to care after discharge; regrettably, people admitted to the hospital with an underlying OUD typically do not receive MOUD and are not connected with subsequent treatment for their condition. To address this gap, we launched a multi-site randomized controlled trial to test the effectiveness of a hospital-based addiction consultation team (the Substance Use Treatment and Recovery Team (START)) consisting of an addiction medicine specialist and care manager team that provide collaborative care and a specified intervention to people with OUD during the inpatient stay...

In order to enhance interdisciplinary collaboration and promote better medication management, a partnered pharmacist medication charting (PPMC) model was piloted in the emergency department (ED) of an Australian referral hospital. The primary objective of this study was to evaluate the impact of PPMC on the timeliness of time-critical medicines (TCMs), completeness of medication orders, and assessment of venous thromboembolism (VTE) risk. This concurrent controlled retrospective pragmatic trial involved individuals aged 18 years and older presenting to the ED from 1 June 2020 to 17 May 2021...
