Frequency of emergency medical service contacts after hospital admissions.

Identifying frequent users of Emergency Medical Services (EMS) in the post-discharge period can potentially direct interventions to prevent deterioration at home. This study aimed to describe the frequency of post-discharge emergency phone calls within 30 days after common medical and surgical categories of hospital admission. A retrospective cohort study retrieved data from the electronic medical record and the EMS Capital Region Denmark database after approval by the Danish Health Data Authority.

Barriers for Responding to Pediatric Out-of-Hospital Cardiac Arrest During Emergency Medical Calls: A Qualitative Study.

Background: Rapid recognition of pediatric out-of-hospital cardiac arrest (POHCA) is a critical component to prompt initiation of bystander interventions. We aimed to investigate barriers for responding to POHCA during emergency medical calls.

Methods And Results: We included all POHCA calls (aged 0-18 years) from the emergency dispatch center in the Capital Region of Denmark between 2018 and 2021 and excluded POHCAs with no resuscitation order, found dead, where trained health professionals were on site, or where there was no possibility for initiation of cardiopulmonary resuscitation.

An assessment of long-term complications following prehospital intraosseous access: A nationwide study.

Background: The guidelines for Advanced Life Support issued by the European Resuscitation Council recommend considering drug delivery through intraosseous access if intravenous access to the vascular bed is not feasible or unsuccessful. Emergency prehospital intraosseous cannulation may theoretically lead to an increased risk of long-term complications such as osteomyelitis, osteonecrosis, or compartment syndrome. Such complications have previously been reported in case reports or small sample case series.

Susceptibility to and severity of SARS-CoV-2 infection according to prescription drug use-an observational study of 46,506 Danish healthcare workers.

Evaluating the Impact of Moderate and Severe Varicella Infections on Danish Children Under 18 Years Old: A Comprehensive Analysis From 2015 to 2023.

Background: Varicella (chickenpox) caused by varicella-zoster virus (VZV) is a highly contagious pediatric disease. While it typically manifests as a mild disease, complications leading to hospitalization are not uncommon. Knowing the current disease burden, seasonality and risk groups is pivotal for evidence-based decisions on the introduction of a varicella vaccine.

Glucagon-like peptide-1 receptor agonist use is associated with reduced risk of out-of-hospital cardiac arrest in women with type 2 diabetes: A nationwide nested case-control study.

Objective: Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) improve cardiovascular outcomes in patients with type 2 diabetes, but few studies have studied the risk of out-of-hospital cardiac arrest (OHCA). We investigated whether GLP-1 RA use reduce OHCA risk in type 2 diabetes when compared to dipeptidyl peptidase-4 inhibitor (DPP-4i) use.

Methods: We identified all patients having a redeemed prescription of a glucose-lowering drug between 1995 and 2019 and excluded patients with a first-time redeemed prescription consisting of insulin.

Incidence and Outcomes After Out-of-Hospital Cardiac Arrest at Train Stations in Denmark.

Background: Following international guidelines, communities have deployed automated external defibrillators at train stations without substantive evidence.

Methods And Results: We geocoded public out-of-hospital cardiac arrests (OHCAs) (2016-2020), automated external defibrillators, and train stations. The stations were divided into the following groups according to passenger flow: 1 (0-499), 2 (500-4999), 3 (5000-9999), and 4 (>10 000) passengers per day.

Prehospital management and outcomes of patients calling with chest pain as the main complaint.

Background: Chest pain is a frequent cause of health care contacts. We examined the prehospital management, in-hospital discharge diagnoses, and mortality of patients calling a non-emergency and emergency medical service with chest pain.

Methods: The Copenhagen Emergency Medical Services (EMS) consists of a non-emergency medical helpline (calls to 1813) and emergency medical service (1-1-2 calls).

Ongoing Opioid Treatment and Symptoms of Myocardial Infarction in Calls to the Emergency Medical Services.

Background: Ongoing opioid treatment can potentially modify symptoms of myocardial infarction (MI) and cause a lack of recognition and treatment delay.

Objectives: The purpose of this study was to examine MI symptoms and the time to hospitalization for patients in ongoing opioid treatment compared to patients without ongoing opioid treatment.

Methods: We evaluated calls to the Copenhagen Emergency Medical Services in Denmark from 2014 to 2018.

Patients' use of Danish emergency medical services before and during the COVID-19 pandemic: a register-based study.

Background: During the COVID-19 pandemic, disturbing images of ambulances unable to respond to the demands for prehospital assistance appeared from several parts of the world. In Denmark, however, a notion occurred that the demands for emergency medical assistance declined. The purpose of this study was to compare the patients' use of the Danish Emergency Medical Services (EMS) before and during the COVID-19 pandemic.

Prehospital Pulse-Dose Glucocorticoid in ST-Segment Elevation Myocardial Infarction: The PULSE-MI Randomized Clinical Trial.

Importance: In patients with ST-segment elevation myocardial infarction (STEMI), acute inflammation is related to the extent of myocardial damage and may increase infarct size. Thus, administration of pulse-dose glucocorticoid in the very early phase of infarction may reduce infarct size.

Objective: To determine the cardioprotective effect of prehospital pulse-dose glucocorticoid in patients with STEMI.

"I think we should wait and see": A qualitative study of call-takers' decision-making in consultations with patients suffering unrecognized myocardial infarction.

Objectives: Call-takers face a complex situation when assessing medical problems in emergency medical services calls. Patients with myocardial infarction experiencing atypical symptoms risk misinterpretation. We examined development in call-takers' decision-making process in telephone consultations with patients having imminent myocardial infarction.

Long-term survival following out-of-hospital cardiac arrest in women and men: Influence of comorbidities, social characteristics, and resuscitation characteristics.

Aim: We aimed to study sex differences in long-term survival following out-of-hospital cardiac arrest (OHCA) compared to the general population, and determined associations for comorbidities, social characteristics, and resuscitation characteristics with survival in women and men separately.

Methods: We followed 2,452 Danish (530 women and 1,922 men) and 1,255 Dutch (259 women and 996 men) individuals aged ≥25 years, who survived 30 days post-OHCA in 2009-2015, until 2019. Using Poisson regression analyses we assessed sex differences in long-term survival and sex-specific associations of characteristics mutually adjusted, and compared survival with an age- and sex-matched general population.

Factors associated with approaching Pilot Peer Support: a cross-sectional study.

Background: Pilot Peer Support Programs (PPSP) have been introduced in Europe as a measure to facilitate commercial pilots' mental health help-seeking in a confidential and non-punitive manner. However, research is scarce regarding what promotes and prevents pilots from approaching PPSP.

Aims: To investigate if, and in which way, different organizational and individual factors are associated with pilots' attitudes towards approaching PPSP, and to examine the prevalence of possible cases of depression and anxiety disorders among commercial pilots in Europe.

Incidence and Survival of Out-of-Hospital Cardiac Arrest in Public Housing Areas in 3 European Capitals.

Background: Strategies to reach out-of-hospital cardiac arrests (called cardiac arrest) in residential areas and reduce disparities in care and outcomes are warranted. This study investigated incidences of cardiac arrests in public housing areas.

Methods: This register-based cohort study included cardiac arrest patients from Amsterdam (the Netherlands) from 2016 to 2021, Copenhagen (Denmark) from 2016 to 2021, and Vienna (Austria) from 2018 to 2021.

Prediction model for future OHCAs based on geospatial and demographic data: An observational study.

This study used demographic data in a novel prediction model to identify areas with high risk of out-of-hospital cardiac arrest (OHCA) in order to target prehospital preparedness. We combined data from the nationwide Danish Cardiac Arrest Registry with geographical- and demographic data on a hectare level. Hectares were classified in a hierarchy according to characteristics and pooled to square kilometers (km2).
