Paramedicine

BACKGROUND: Ambulance services need to identify and prioritise patients with sepsis for early hospital assessment. We aimed to determine the accuracy of early warning scores alongside paramedic diagnostic impression to identify sepsis that required urgent treatment. METHODS: We undertook a retrospective diagnostic cohort study involving adult emergency medical cases transported to Sheffield Teaching Hospitals ED by Yorkshire Ambulance Service in 2019. We used routine ambulance service data to calculate 21 early warning scores and categorise paramedic diagnostic impressions as sepsis, infection, non-specific presentation or other presentation...

INTRODUCTION: Sweden is facing a surge of gun violence that mandates optimized prehospital transport approaches, and a survey of current practice is fundamental for such optimization. Management of severe, penetrating trauma is time sensitive, and there may be a survival benefit in limiting prehospital interventions. An important aspect is unregulated transportation by police or private vehicles to the hospital, which may decrease time but may also be associated with adverse outcomes...

Early treatment is the mainstay of sepsis therapy. We suspected that early recognition of sepsis by prehospital healthcare providers may shorten the time for antibiotic administration in the emergency department. We retrospectively evaluated all patients above 18 years of age who were diagnosed with sepsis or severe infection in our emergency department between 2018 and 2020. We recorded the suspected diagnosis at the time of presentation, the type of referring healthcare provider, and the time until initiation of antibiotic treatment...

BACKGROUND: Epinephrine is the first-line treatment for anaphylaxis but is often replaced with antihistamines or corticosteroids. Delayed epinephrine administration is a risk factor for fatal anaphylaxis. Convincing data on the role of antihistamines and corticosteroids in anaphylaxis management are sparse. OBJECTIVE: To establish the impact of prehospital treatment with epinephrine, antihistamines, and/or corticosteroids on anaphylaxis management. METHODS: Patients presenting with anaphylaxis were recruited prospectively and retrospectively in 10 Canadian and 1 Israeli emergency departments (EDs) between April 2011 and August 2022, as part of the Cross-Canada Anaphylaxis REgistry...

INTRODUCTION: Mixed methods research, a methodology entailing the integration of qualitative and quantitative data within a single study, offers researchers the ability to investigate complex processes and systems in health and healthcare. The collective strength gained through the data combination can provide an enhanced understanding of research problems, providing an ideal solution to understanding complex clinical issues in a range of settings. In pre-hospital practice, where often uncontrollable variables and environmental considerations increase healthcare complexity, mixed methods has emerged as a valuable approach to research...

AIM: The aim of this professional practice paper is to provide a critical commentary on displaced risk among perinatal and neonatal patients attended to by the ambulance service. BACKGROUND: NHS services across the United Kingdom are currently facing unprecedented demand and increased scrutiny in their ability to provide safe and personalised care to patients. While current focus in the system centres around addressing social care demand, hospital bed capacity, planned care waiting times, staffing and ambulance handover delays, a less explored cohort of patients impacted by the current healthcare crisis is perinatal and neonatal populations attended to by the ambulance service...

INTRODUCTION: Chronic obstructive pulmonary disease (COPD) and asthma exacerbation are two common emergency situations. This study aimed to investigate the impact of pre-hospital dexamethasone initiation on treatment outcomes of these patients. METHODS: In this retrospective cross-sectional and comparative study, data from the emergency medical service (EMS) care report of patients with a final diagnosis of asthma or COPD, coded with Thailand's emergency medical triage protocol, collected between January 1, 2021, and October 31, 2022, were used...

BACKGROUND: Prehospital interventions may increase the time to definitive care. Compared to ground ambulance, we hypothesize improved mortality for patients with isolated, penetrating torso injuries transported via private vehicle. METHODS: We reviewed the National Trauma Data Bank (2017-2021) for adults with isolated, penetrating torso injuries stratified by mechanism (stabbing vs. firearm) and transport mode (private vehicle vs. ground ambulance). We performed a multivariable logistic regression to estimate the effect of transport mode on mortality...

Background/problem: Information transfer between emergency medical services (EMS) and emergency medicine (EM) is at high risk for omissions and errors. EM awareness of prehospital medication administration affects patient management and medication error. In April 2020, we surveyed emergency physicians and emergency department nurse practitioners (NPs) and physician assistants (PAs) regarding the EMS handoff process. Emergency physicians and NPs/PAs endorsed knowing what medications were given, or having received direct verbal handoff from EMS "Often" or "Always" only 20% of the time ( n  = 71), identifying a need to improve the written handoff process...

PURPOSE: Tourniquets are a mainstay of life-saving hemorrhage control. The US military has documented the safety and effectiveness of tourniquet use in combat settings. In civilian settings, events such as the Boston Marathon bombing and mass shootings show that tourniquets are necessary and life-saving entities that must be used correctly and whenever indicated. Much less research has been done on tourniquet use in civilian settings compared to military settings. The purpose of this study is to describe the prehospital use of tourniquets in a regional EMS system served by a single trauma center...

BACKGROUND: Whether the National Early Warning Score 2 (NEWS2) can effectively discriminate the severe/critical state of patients with coronavirus disease 2019 (COVID-19) at the prehospital stage remains unknown. We aimed to assess the performance of NEWS2 in rapidly discriminating severe/critical COVID-19 and its relationship with prehospital medical services. METHODS: Six illness severity scores of 414 patients were calculated at the prehospital stage. Receiver operating characteristic curves were generated to explore the ability of these scores to discriminate severe/critical patients from mild/moderate patients...

BACKGROUND: Prehospital post-resuscitation hypotension and hypoxia have been associated with adverse outcomes in the context of out-of-hospital cardiac arrest (OHCA). We aimed to investigate the association between clinical outcomes and post-resuscitation hypoxia alone, hypotension alone, and combined hypoxia and hypotension. METHODS: We used the 2018-2021 ESO annual datasets to conduct this study. All EMS-treated non-traumatic OHCA patients who had a documented prehospital return of spontaneous circulation (ROSC) and two or more SpO2 readings and systolic blood pressures recorded were evaluated for inclusion...

BACKGROUND: Prehospital emergency physicians have to navigate complex decision-making in out-of-hospital cardiac arrest (OHCA) treatment that includes ethical considerations. This study explores Danish prehospital physicians' experiences of ethical issues influencing their decision-making during OHCA. METHODS: We conducted a multisite ethnographic study. Through convenience sampling, we included 17 individual interviews with prehospital physicians and performed 22 structured observations on the actions of the prehospital personnel during OHCAs...

Frostbite remains a severe medical condition that causes long-lasting sequelae and can threaten military operations. Information on prehospital treatment of frostbite is scarce and existing guidelines are aimed at the general population.This paper provides a guideline on prehospital emergency care of frostbite in the (Netherlands) Armed Forces. The insights gained from studies reporting on frostbite treatment in the prehospital setting were combined with the expert opinions of the authors and applied to the military context...

OBJECTIVE: It is unclear if prehospital intubation improves survival in patients with traumatic brain injury. We performed a systematic review and meta-analysis to assess the impact of prehospital intubation on mortality rates of traumatic brain injury. METHODS: PubMed, CENTRAL, Web of Science, and Embase databases were searched without any language restriction up to 20 June 2022 for all types of comparative studies reporting survival of traumatic brain injury patients based on prehospital intubation...

The aim of this study was to analyze the mortality of polytrauma patients and identify prediction parameters. A further aim was to create from the results a score for the prehospital predictive evaluation of 30-day survival. The study was conducted with a retrospective, observational design and was carried out unicentrically at a Level 1 Trauma Center. During the 4-year investigation period, patients with an Injury Severity Score (ISS) ≥ 16 were examined and their demographic basic data, laboratory values, and vital parameters were recorded...

BACKGROUND: Appendicitis is the most common reason children undergo acute general surgery but international, population-level disparities exist. This is hypothesised to be caused by preoperative delay and differential access to surgical care. The impact of prehospital factors on paediatric appendicitis severity in New Zealand is unknown. METHODS: A prospective, multicentre cohort study with nested parental questionnaire was conducted by a national trainee-led collaborative group...

BACKGROUND: In October 2021, French acute care societies jointly published cognitive aids to standardise practices and limit cognitive biases to ensure greater safety in management of severe trauma patients. The aim of the study was to evaluate the impact of a checklist on emergency physicians' adherence to the recommendations. METHODS: This prospective before-and-after study study took place in a French mobile emergency and resuscitation service. All adults trauma patients referred to hospital were included...
