Review
Migraine is a common condition that can carry considerable risk to aeromedical duties. Because randomized controlled trials are not an appropriate method to evaluate flight safety risk for medical conditions that may cause subtle or sudden incapacitation, the determination of fitness-to-fly must be based on risk assessments informed by extrapolated evidence. Therefore, we conducted a review of current literature to provide background information to inform the aeromedical risk assessment of migraine using a risk matrix approach. We identified studies on topics pertinent to conducting an aeromedical risk assessment of migraine. We generated an overview of the literature synthesizing the findings of articles retrieved from searches of Scopus, Ovid, PubMed, and the Cochrane Library published in English from all years, in both general and aircrew populations. International headache and neurology guidelines, as well as headache policies from the U.S. Air Force, were also reviewed. This review includes information on the following topics relevant to conducting an evidence-based risk assessment of migraine: diagnosis, prevalence, incidence, natural course, clinical presentation, triggers, comorbidities, neuroimaging, implications of family history, and efficacy of pharmacological and nonpharmacological therapies. This review summarizes current literature on migraine for use in a risk matrix approach to the aeromedical assessment of migraine in prospective and current aircrew. Awareness of the most current epidemiological data related to a variety of migraine parameters facilitates an evidence-based risk assessment of migraine in aircrew and requires iterative updates as new information becomes available.

OBJECTIVE
In Queensland, where a person experiences a major disturbance in their mental capacity, and is at risk of serious harm to self and others, an emergency examination authority (EEA) authorises Queensland Police Service (QPS) and Queensland Ambulance Service (QAS) to detain and transport the person to an ED. In the ED, further detention for up to 12 h is authorised to allow the examination to be completed. Little published information describes these critical patient encounters.
METHODS
Queensland's Public Health Act (2005), amended in 2017, mandates the use of the approved EEA form. Data were extracted from a convenience sample of 942 EEAs including: (i) patient age, sex, address; (ii) free text descriptions by QPS and QAS officers of the person's behaviour and any serious risk of harm requiring urgent care; (iii) time examination period commenced; and (iv) outcome upon examination.
RESULTS
Of 942 EEA forms, 640 (68%) were retrieved at three 'larger central' hospitals and 302 (32%) at two 'smaller regional' hospitals in non-metropolitan Queensland. QPS initiated 342 (36%) and QAS 600 (64%) EEAs for 486 (52%) males, 453 (48%) females and two intersexes (<1%), aged from 9 to 85 years (median 29 years, 17% aged <18 years). EEAs commonly occurred on weekends (32%) and between 2300 and midnight (8%), characterised by 'drug and/or alcohol issues' (53%), 'self-harm' (40%), 'patient aggression' (25%) and multiple prior EEAs (23%). Although information was incomplete, most patients (78%, n = 419/534) required no inpatient admission.
CONCLUSIONS
EEAs furnish unique records for evaluating the impacts of Queensland's novel legislative reforms.

IMPORTANCE
Early warning scores (EWSs) are designed for in-hospital use but are widely used in the prehospital field, especially in select groups of patients potentially at high risk. To be useful for paramedics in daily prehospital clinical practice, evaluations are needed of the predictive value of EWSs based on first measured vital signs on scene in large cohorts covering unselected patients using ambulance services.
OBJECTIVE
To validate EWSs' ability to predict mortality and intensive care unit (ICU) stay in an unselected cohort of adult patients who used ambulances.
DESIGN, SETTING, AND PARTICIPANTS
This prognostic study conducted a validation based on a cohort of adult patients (aged ≥18 years) who used ambulances in the North Denmark Region from July 1, 2016, to December 31, 2020. EWSs (National Early Warning Score 2 [NEWS2], modified NEWS score without temperature [mNEWS], Quick Sepsis Related Organ Failure Assessment [qSOFA], Rapid Emergency Triage and Treatment System [RETTS], and Danish Emergency Process Triage [DEPT]) were calculated using first vital signs measured by ambulance personnel. Data were analyzed from September 2022 through May 2023.
MAIN OUTCOMES AND MEASURES
The primary outcome was 30-day-mortality. Secondary outcomes were 1-day-mortality and ICU admission. Discrimination was assessed using area under the receiver operating characteristic curve (AUROC) and area under the precision recall curve (AUPRC).
RESULTS
There were 107 569 unique patients (52 650 females [48.9%]; median [IQR] age, 65 [45-77] years) from the entire cohort of 219 323 patients who used ambulance services, among whom 119 992 patients (54.7%) had called the Danish national emergency number. NEWS2, mNEWS, RETTS, and DEPT performed similarly concerning 30-day mortality (AUROC range, 0.67 [95% CI, 0.66-0.68] for DEPT to 0.68 [95% CI, 0.68-0.69] for mNEWS), while qSOFA had lower performance (AUROC, 0.59 [95% CI, 0.59-0.60]; P vs other scores < .001). All EWSs had low AUPRCs, ranging from 0.09 (95% CI, 0.09-0.09) for qSOFA to 0.14 (95% CI, 0.13-0.14) for mNEWS.. Concerning 1-day mortality and ICU admission NEWS2, mNEWS, RETTS, and DEPT performed similarly, with AUROCs ranging from 0.72 (95% CI, 0.71-0.73) for RETTS to 0.75 (95% CI, 0.74-0.76) for DEPT in 1-day mortality and 0.66 (95% CI, 0.65-0.67) for RETTS to 0.68 (95% CI, 0.67-0.69) for mNEWS in ICU admission, and all EWSs had low AUPRCs. These ranged from 0.02 (95% CI, 0.02-0.03) for qSOFA to 0.04 (95% CI, 0.04-0.04) for DEPT in 1-day mortality and 0.03 (95% CI, 0.03-0.03) for qSOFA to 0.05 (95% CI, 0.04-0.05) for DEPT in ICU admission.
CONCLUSIONS AND RELEVANCE
This study found that EWSs in daily clinical use in emergency medical settings performed moderately in the prehospital field among unselected patients who used ambulances when assessed based on initial measurements of vital signs. These findings suggest the need of appropriate triage and early identification of patients at low and high risk with new and better EWSs also suitable for prehospital use.

Review
BACKGROUND
Even though the traditional focus in emergency care is on life-threatening medical crisis, ambulance clinicians frequently encounter patients with mental illness, including suicidal ideation. A suicide is preceded by a complex process where most of the suicidal ideation is invisible to others. However, as most patients seek healthcare in the year before suicide, ambulance clinicians could have an important part to play in preventing suicide, as they encounter patients in different phases of the suicidal process.
AIM
The aim of this study was to describe ambulance clinicians' conceptions of responsibility when encountering patients in a suicidal process.
RESEARCH DESIGN
A qualitative inductive design using a phenomenographic approach was used.
PARTICIPANTS AND RESEARCH CONTEXT
Twenty-seven ambulance clinicians from two regions in southern Sweden were interviewed.
ETHICAL CONSIDERATIONS
The study was approved by the Swedish Ethical Review Authority.
FINDINGS
Three categories of descriptions captured a movement from responding to a biological being to responding to a social being. Conventional responsibility was perceived as a primary responsibility for emergency care. In conditional responsibility, the patient's mental illness was given only limited importance and only if certain conditions were met. Ethical responsibility was perceived to have its primary focus on the encounter with the patient and listening to the patient's life story.
CONCLUSIONS
An ethical responsibility is favourable regarding suicide prevention in ambulance care, and competence development in mental illness and conversation skills could enable ambulance clinicians to have conversations with patients about suicidal ideation.

Review
BACKGROUND
With millions of unscheduled patient contacts every year and increasing call outs clustered around the most deprived communities, it is clear the ambulance sector could have a role to play in improving population health. However, the application and value of a public health approach within the ambulance sector has not been comprehensively explored. A scoping review was undertaken to explore the role of the ambulance sector in the delivery of public health interventions and what impact this has on population health and ambulance sector outcomes.
METHODS
A search strategy was developed on MEDLINE and translated to other major medical and health related bibliographic databases (Embase; CINAHL; HMIC; Science and Social Sciences Citation Index; Cochrane Library) to identify literature published since 2000 in OECD countries. Targeted grey literature, reference list, and citation searching was also carried out. Search results were downloaded to Microsoft Excel and screened by three reviewers according to pre-determined inclusion / exclusion criteria. Data from included studies, such as the type of activity noted within the paper, the population involved and the public health approach that was utilised, was extracted from within the paper using a data extraction form and narratively synthesised.
RESULTS
Fifty-two references were included in the final review (37 database searching; 9 reference list searching; 6 grey literature). Included articles were categorised according to the relevant public health domains and subdomains as articulated by the UK Faculty of Public Health: 1. Health improvement domain: Public health education and advice (Health promotion sub-domain) (n=13) Emergency Services personnel providing vaccines (Disease prevention sub-domain) (n=1) 2. Health care public health domain Paramedicine (Service delivery sub-domain) (n=30) Screening tools and referral pathways used by the ambulance sector (Service delivery sub-domain) (n=28) Health intelligence using ambulance sector data (population health management sub-domain) (n=26) Of note, some domains (e.g. health protection) returned nil results.
DISCUSSION
The scoping review demonstrates the breadth of public health related activities in which the ambulance sector is involved. However, an overemphasis on demand management outcomes precludes definitive conclusions on the impact of ambulance sector-led public health initiatives on public health outcomes. Future evaluations of public health initiatives should incorporate wider health system perspectives beyond the immediately apparent remit of the ambulance sector.

INTRODUCTION
Falls in the community can have major impacts on patient lives. There can be long lasting physical and psychological consequences of a fall and subsequent long lie. The annual burden to ambulance services responding to falls at home is high. Affordable devices to help people get up from the floor, or reduce the risk of a long lie, would be useful and widely applicable.
CASE REPORT
We present the case of 2 families who successfully used an air mattress and a bath lift to get the fallen person up off the floor following a fall, when they had previously called an ambulance. This has reduced their dependence on the ambulance service and has improved their confidence following falls.
DISCUSSION/CONCLUSION
Affordable devices such as air mattresses can help people off the floor following a fall and prevent long lies as well as reduce the number of ambulance call outs.

Review
Over the past decades, continuous technological advances and the availability of novel therapies have enabled treatment of more acute medical conditions than ever before. Many of these treatments, such as intravenous thrombolysis and mechanical thrombectomy for acute ischemic stroke, are highly time sensitive. This has raised interest in shifting advanced acute care from hospitals to the prehospital setting. Key objectives of advanced prehospital stroke care may include (1) early targeted treatments in the prehospital setting, for example, intravenous thrombolysis for acute stroke, and (2) advanced prehospital diagnostics such as prehospital large vessel occlusion and intracranial hemorrhage detection, to help inform patient triage and potentially reduce subsequent workload in emergency departments. Major challenges that may hamper a swift transition to more advanced prehospital care are related to conducting clinical trials in the prehospital setting to provide sufficient evidence for emergency interventions, as well as ambulance design, infrastructure, emergency medical service personnel training and workload, and cost barriers. Utilizing new technologies such as telemedicine, mobile stroke units and portable diagnostic devices, customized software applications, and smart storage space management may help surmount these challenges and establish efficient, targeted care strategies that are achievable in the prehospital setting. In this article, we delineate the paradigm of shifting advanced stroke care to the prehospital setting and outline future directions in providing evidence-based, patient-centered prehospital care. While we use acute stroke as an illustrative example, these principles are not limited to stroke patients and can be applied to prehospital triage for any time-critical disease.
