BACKGROUND
Although paramedics can use adrenaline autoinjectors (AAIs) during their duties, the actual conditions of their use and the challenges faced remain unclear. We investigated the actual situation and issues pertaining to creating an environment in which paramedics can operate AAIs more effectively.
METHODS
A web-based survey was conducted among paramedics who participated in a web-based training session related to their latest knowledge on food allergies and emergency responses in 2022. The survey items included practice and training environments, practices of AAI administration, and regarding AAI administration.
RESULTS
Seventy paramedics responded to the survey. Twenty-eight respondents (40%) had experienced cases in which they wished they had an AAI in their work to date, but only one had actually administered one. Thirty-four (49%) indicated that it would be good to have an AAI in the ambulance at all times; 48 (69%) were not concerned about the use of AAI, and the level of concern about its use was significantly related to length of service. The study also revealed that paramedics do not have an adequate training environment regarding AAI.
CONCLUSION
Few paramedics have experience in administering AAI, although they are aware of the need for it. For more effective use of AAI, it is necessary to establish a training environment to familiarize paramedics with anaphylaxis and an environment that enables them to use AAI promptly in the field.

AIM
The cohort of patients in which cardiac arrest centres (CAC) in rural and suburban populations confer the greatest survival benefit remains unclear. The aim of this study was to assess whether the transfer of resuscitated Utstein-comparator out-of-hospital cardiac arrest (OHCA) patients direct to a CAC was associated with improved survival to hospital discharge compared to patients conveyed to non-specialist centres.
METHODS
A consecutive sample of adult (≥18 years old) Utstein-comparator patients (witnessed collapse and initial shockable rhythm) were included from the East of England Ambulance Service NHS Trust Utstein resuscitation registry; 2018-2022. Logistic regression was used to compare survival to discharge in patients transported to CACs compared with patients transported to non-specialist centres.
RESULTS
During the study period, resuscitation was attempted in 18,276 OHCA patients. N = 2448 (13.4%) met the Utstein-comparator definition and 1151 patients were included in the final analysis; per protocol. Survival was greater for patients conveyed directly to a CAC (n = 768, 60.7%) compared to non-specialist centres (n = 383, 47.3%); adjusted OR 1.44 (95%CI 1.07-1.94),p = 0.017. Amongst the centres analysed in this study, there was significant inter-hospital variability in survival between CACs (p = 0.017). There was no association between patient volume and survival (p = 0.850).
CONCLUSION
Direct transport to a cardiac arrest centre was associated with a 44% increase in the odds of survival compared to conveyance to a non-specialist centre for resuscitated adult patients presenting with witnessed collapse and initial shockable OHCA rhythm.

The global imperative to expand prehospital emergency care in low and middle-income countries to reduce health disparities and improve outcomes for time-sensitive health conditions is well established in academic literature and public policy discussions. However, the governance and legal frameworks essential for the strategic development of prehospital systems remain understudied and inadequately addressed. This paper delves into the critical role of governance in prehospital systems, emphasizing its impact on equity, human rights, and the provision of timely, quality emergency care. Health system governance, defined as a complex interplay of mechanisms, processes, and institutions, is a neglected yet pivotal component of prehospital care. By highlighting previously described barriers, we underscore the opportunity to strengthen prehospital care through improved governance, particularly in leadership and legislative standards. Drawing on the World Health Organization's Health System Building Blocks and the Emergency Care System Framework, we elucidate the multifaceted nature of governance in the prehospital context, including the coordination of diverse stakeholders, the establishment of standards, and the creation of accountability mechanisms. We emphasize the importance of applying a human rights perspective to governance, ensuring non-discriminatory and timely access to emergency care. Through the application of an established governance framework of 10 principles to assess prehospital system governance, we offer policymakers and stakeholders a structured approach to identify weaknesses, propose solutions, and evaluate progress in the prehospital system. To provide practical insights, we present a contemporary case study of Ghana's National Ambulance Service Act and the Health Institutions and Facilities Act of 2011, which establish a structured approach to governance and oversight while reflecting Ghana's commitment to advancing emergency care yet faces common challenges to operationalizing the laws. We advocate for a renewed focus on governance as an essential building block for effective prehospital emergency care. By providing a comprehensive framework and case study analysis, the paper offers actionable insights to guide policymakers and stakeholders in developing and evaluating governance initiatives that improve the availability, accessibility, acceptability, and quality of prehospital care globally.

BACKGROUND
Tranexamic acid (TXA) decreases mortality in injured patients and should be administered as soon as possible. Despite international guidelines recommending TXA in the prehospital setting, its use remains low. The aim of this study was to assess the prehospital administration of TXA for injured patients in a Swiss region.
METHODS
We conducted a retrospective observational study in Switzerland between 2018 and 2021. Inclusion criteria were injured patients ≥18 years for whom an ambulance or helicopter was dispatched. The exclusion criterion was minor injury defined by a National Advisory Committee for Aeronautics score <3. The primary outcome was the proportion of patients treated with TXA according to guidelines. The European guidelines were represented by the risk of death from bleeding (calculated retrospectively using the Bleeding Audit for Trauma and Triage (BATT) score). Factors impacting the likelihood of receiving TXA were assessed by multivariate analysis.
RESULTS
Of 13 944 patients included in the study, 2401 (17.2%) were considered at risk of death from bleeding. Among these, 257 (11%) received prehospital TXA. This represented 38% of those meeting US guidelines. For European guidelines, the treatment rate increased with the risk of death from bleeding: 6% (95% CI 4.4% to 7.0%) for low risk (BATT score 3-4); 13% (95% CI 11.1% to 15.9%) for intermediate risk (BATT score 5-7); and 21% (95% CI 17.6% to 25.6%) for high risk (BATT score ≥8) (p<0.01). Women and the elderly were treated less often than men and younger patients, irrespective of the risk of death from bleeding and the mechanism of injury.
CONCLUSION
The proportion of injured patients receiving TXA in the prehospital setting of the State of Vaud in Switzerland was low, with even lower rates for women and older patients. The reasons for this undertreatment are probably multifactorial and would require specific studies to clarify and correct them.

BACKGROUND
Prior literature suggests that mass gathering events pose challenges to an emergency medical services (EMS) system. We aimed to investigate whether events influence EMS call rates.
MATERIALS AND METHODS
This study is a retrospective review of all primary response ambulance calls in Rhode Island (US) between January 1st, 2018 and August 31st, 2022. The number of EMS calls per day was taken from the state's EMS registry. Event data was collected using a Google (Google LLC, Mountain View, CA) search. We used separate Poisson regression models with the number of ambulance calls as the dependent and the social event categories sports, agricultural, music events, and public exhibitions as independent variables. All models controlled for the population at risk and the period of the COVID-19 pandemic. Results are presented as increases or decreases in calls per 100,000 inhabitants from the mean over the study period.
RESULTS
The mean number of daily EMS calls was 38 ± 4 per 100,000 inhabitants. EMS encountered significantly more missions on days with music events (+3, 95% CI [2; 3]) and public exhibitions (+2, 95% CI [1; 2]). In contrast, days with agricultural events were associated with fewer calls (-1, 95% CI [-1; 0]). We did not find any effect of sports events on call rates.
CONCLUSION
Increased ambulance call volumes are observed on days with music events and public exhibitions. Days with agricultural events are associated with fewer EMS calls.

AIMS
To capture the types and content of healthcare encounters following severe hypoglycemia requiring emergency medical services (EMS) and to correlate their features with subsequent risk of severe hypoglycemia.
METHODS
A retrospective cohort was obtained by linking data from a multi-state health system and an advanced life support ambulance service. This identified 1977 EMS calls by 1028 adults with diabetes experiencing hypoglycemia between 1/1/2013-12/31/2019. We evaluated the healthcare engagement over the following 7 days to identify rates of discussion of hypoglycemia, change of diabetes medications, glucagon prescribing, and referral for diabetes.
RESULTS
Rates of hypoglycemia discussion increased with escalating levels of care, from 11.5 % after EMS calls without emergency department (ED) transport or outpatient clinical encounters to 98 % among hospitalized patients with outpatient follow-up. EMS transport and outpatient follow-up were associated with significantly higher odds of discussion of hypoglycemia (OR 60 and OR 22.1, respectively). Interventions were not impacted by previous severe hypoglycemia within 30 days. Prescription of glucagon was rare among all patients.
CONCLUSIONS
Interventions to prevent recurrent hypoglycemia increase with escalating levels of care but remain inadequate and inconsistent with clinical guidelines. Greater attention is needed to ensure timely diabetes-related follow-up and treatment modification for patients experiencing severe hypoglycemia.

BACKGROUND
Various prognosticative approaches to assist in recognizing clinical deterioration have been proposed. To date, early warning scores (EWSs) have been evaluated in hospital with limited research investigating their suitability in the prehospital setting. This study evaluated the predictive ability of established EWSs and other clinical factors for prehospital clinical deterioration.
METHODS
A retrospective cohort study investigating adult patients of all etiologies attended by Queensland Ambulance Service paramedics between January 1, 2018, and December 31, 2020, was conducted. With logistic regression, several models were developed to predict adverse event outcomes. The National Early Warning Score (NEWS), Modified Early Warning Score (MEWS), Queensland Adult Deterioration Detection System (Q-ADDS), and shock index were calculated from vital signs taken by paramedics.
RESULTS
A total of 1,422,046 incidents met the inclusion criteria. NEWS, MEWS, and Q-ADDS were found to have comparably high predictive ability with area under the receiver operating characteristic curve (AUC-ROC) between 70% and 90%, whereas shock index had relatively low AUC-ROC. Sensitivity was lower than specificity for all models. Although established EWSs performed well when predicting adverse events, these scores require complex calculations requiring multiple vital signs that may not be suitable for the prehospital setting.
CONCLUSIONS
This study found NEWS, MEWS, and Q-ADDS all performed well in the prehospital setting. Although a simple shock index is easier for paramedics to use in the prehospital environment, it did not perform comparably to established EWSs. Further research is required to develop suitably performing parsimonious solutions until established EWSs are integrated into technological solutions to be used by prehospital clinicians in real time.

Two healthy Landrace pigs anaesthetized with propofol suffered rapid onset of fatal sepsis. Clinical signs included severe arterial hypotension, loss of peripheral oxygenation, low end-tidal CO, clinical onset of pulmonary oedema and cardiac dysfunction. Gross and histopathological examination revealed loss of vascular integrity with severe lung oedema and congestion, haemorrhages in several organs and fluid leakage into body cavities. Large numbers of Gram-negative bacteria, primarily sp., were present in the anaesthetic infusion containing propofol and were also cultured from internal organs of both pigs. The propofol was likely contaminated by bacteria after inappropriate handling and storage in the operating room. This report illustrates the potential for severe nosocomial infection when applying propofol in animals and humans and may serve as a reminder of the importance of strict aseptic practice in general, and specifically in the handling of this anaesthetic agent.
