Filter by:To determine the clinical effectiveness of hypothermia treatment in patients with out-of-hospital cardiac arrest complicating acute myocardial infarction.
Out-of-hospital cardiac arrest is a leading cause of death worldwide and patient outcome vary substantially throughout regions suggesting further evaluation and potential for improvement.When focussing on subgroups of OHCA, data in certain areas remains scarce and the need of revised guidelines is evident. Furthermore, enhanced knowledge on these varieties of OHCA's apply to substantial number of patients, also among vulnerable populations. The Danish Emergency Medical System introduced a nationwide registry of electronic medical reports in 2016. This report system allows electronic searches and thereby the opportunity to identify subgroups of OHCA's. Thus, this novel reporting enables the evaluation of new characteristics of cardiac arrests of non-cardiac origin, in cases where an automated external defibrillator (AED) is retrieved but did not recommend defibrillation and finally in OHCA related to foreign body obstruction. With the advantages of artificial intelligence, this project will enhance and strengthen data from the Danish Cardiac Arrest Registry. It may substitute the manual validation of the around 9000 cases per year in Denmark. Further, it proposes improvement of quality and development of observational health research.
This study evaluates data from patients in The Danish Medical Service electronical registry over a 6-year period from 2016 to 2021 with traumatic cardiac arrest. The objective of this study is to use artificial intelligence to evaluate reversible causes and relevant circumstances regarding traumatic OHCA in order to improve treatment and survival.
While regular exercise is known to prevent cardiovascular disorders, exercise might also trigger acute cardiac events such as cardiac arrest. This study examines the incidence, prognosis and outcomes of out-of-hospital cardiac arrest (OHCA) related to exercise in the general population of Denmark. This retrospective cohort study examins all OHCAs in the Danish Cardiac Arrest Registry from 2016 to 2019 in Denmark. OHCA related to exercise were identified in the nationwide electronic database and coupled to the patient register. OHCA related to exercise was defined as occurring during or up to one hour after exercise of moderate or vigorous intensity. Descriptive statistics are used together with an adjusted multivariate logistic regression model to assess predefined factors of interest.
Blood samples are collected and stored in a biobank for later analysis of circulating substances in peripheral blood and genetic variations in patients with severe critical illness and risk of death. The aim is to analyze stored samples in order to identify substances that can help predict the outcome of critically ill patients, but also to optimize treatment and possibly prevent serious illness and death in the future.
The purpose of this observational study is to assess the effectiveness of Curodont Repair Fluoride Plus (CRFP) compared to other tooth-specific treatments (silver diamine fluoride (SDF), sealants, or other FDA-approved treatments) in preventing progression to cavitation in patients with at least one early non-cavitated dental caries lesion. The study will also evaluate the effectiveness of CRFP in comparison to no tooth-specific treatment control groups, including whole mouth treatments such as: 2.26% fluoride varnish, 1.23% fluoride foam, and 5000 ppm fluoride prescription toothpaste; and no treatment, on caries arrest and in preventing progression to cavitation in patients with at least one early non-cavitated dental lesion.
It's crucial to determine whether a pulse is present or not in patient with cardiac arrest. But more and more studies have shown that manual palpation is unreliable for detecting pulse 1-4. Failure to detect pulselessness may cause delay of chest compression and directly affect the patient's outcome. Likewise, failure to rapidly detect return of spontaneous circulation may cause prolonged chest compression and increase associated injury during resuscitation. More and more studies have demonstrated that echo guided pulse detection is feasible 5-7. The aim of our study is to check carotid pulse via ultrasound. This is a prospective study and the patient selection is in-hospital or out of hospital cardiac arrest. A curvilinear ultrasonography transducer is used and placed transversely on either right/left carotid artery under pulsed-wave doppler mode to check whether the pulse is present or not. The result of ultrasonography will be compared with manual palpation and to determine the accuracy and effectiveness of clinical usage.
A controlled clinical trial will be performed. School children from the age of 10 to 11 will be selected to learn basic life support (BLS) in a primary school of Zaragoza. One of the groups will learn BLS in two consecutive years and the other group will learn BLS only the first year. The investigators think that the knowledge will be better in the group that receives two interventions.
Background: Foreign body airway obstruction (FBAO) is often described as an uncommon cause of Out of Hospital Cardiac Arrest (OHCA) accounting for approximately 1.4% of all OHCA. Reported incidents rates of FBAO causing cardiac arrest are unclear, and first aid by layperson are not well described. The aim of the epidemiological part of the study is: - to investigate information on actions taken by EMS-personnel and laypersons - to investigate outcomes of hypoxic Cardiac Arrest due to foreign body airway obstruction in Denmark - to increase overall survival. propose new guidelines and strategies to increase survival from OHCA caused by FBAO. The aim of advanced text-string search algorithm part of the study is - To investigate if an advanced text-string search algorithm can identify FBAO in medical records with high sensitivity Methods: National data will be collected from the verified 2016-2019 Danish OHCA register, and cases with FBAO prior to OHCA will selected via a direct marking by external validation and advanced text search. Patients reported as indisputably deceased (late signs of death) was excluded. Incidence rates per 100.000 citizens, survival rates to hospital and first aid actions by layperson are presented. A pilot study have been conducted in regional data from 2016-2019 and the study group have concluded that, a national study is feasible with the current amount of data and the used methodology. Expected outcome: This study will enable targeted campaigns aimed at increasing survival from OHCA caused by FBAO. Potential campaigns might target the food items provided to potential vulnerable groups and guide focus for first aid recommendations. Further, with a deeper understanding of which airway management procedures most often are successful, it will be possible to improve EMS treatments of vulnerable groups. Finally, a novel method of extracting information from the electronic medical records will be developed creating the foundation for future works on other prehospital conditions
Background: OHCA is a rare condition for children and young adults. Overall incidence rates are reported as 3.3-5.97 per 100.000 inhabitants. Previous studies from different data sources have identified a diverse and slightly incompatible etiologies. The purpose of this investigation was to analyze presumed etiologies of pediatric OHCA and report incident and survival rates. Further the investigators wish to present central characteristics of pediatric OHCA in Denmark. Methods: Data will be collected from the verified 2016-2019 Danish OHCA register. Inclusion criteria were age ≤ 16 years at the time of the event. All included EMS reports will read by two authors [MGH and TWJ] and the presumed reversible cause assigned to each case. Incidence rates per 100.000 citizens, survival rates to hospital, initial rhythm, use of AED by laypersons, EMS treatment and presumed etiology are reported. To test feasibility a study was conducted in 2018, on the 56 verified cases of children with OHCA was reported in the capital region of Denmark in 2016-2018 (among 1.8 million inhabitants). Incident rates were 0.83-1.34 per 100.000 inhabitants per year. Preliminary data show survival to hospital was 46% which was markedly higher than the adult population (28%, p = 0.002). The most common cause of OHCA was hypoxia (50%) followed by trauma/hypovolemia (14%) and others (7%). Approximately 23% did not present with an apparent etiology. Hereditary disorders as the primary cause was noted in 7% of the cases. The conclusion from the feasibility study is that the study is possible and that a reasonable proportion of pediatric OHCA can be analyzed from EMS medical reports. Expected outcome: Variables included in the study: age, gender, initial rhythm, etiology of cardiac arrest, event location, observation of occurrence, cardio-pulmonary-resuscitation (CPR), defibrillation and use automatic external defibrillators (AEDs), EMS-response time, hospitalization, return-of-spontaneous-circulation (ROSC), state at hospital admission, 30-day survival, airway management and use of epinephrine.
