Filter by: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. See the dedicated study protocol for an extended description of the variables and associated analyses.
Cardiac arrest is the number one cause of death in Canada. It is often the first symptom of cardiac disease for the victims. Eighty-five percent of victims collapse in their own home. Fifty percent collapse in the presence of a family member. Bystander cardiopulmonary resuscitation (CPR) can improve the chance to survive a cardiac arrest by three to four times, but needs to be started quickly. In most communities, less than 30% of victims receive CPR before the ambulance arrives. Currently, only 8% of cardiac arrest victims can leave the hospital alive. Many things have been tried to improve the number of times people do CPR. So far, the only thing that really increased the number of times that someone did CPR is when 9-1-1 attendants started to give CPR instructions to callers over the phone. The only problem is that about 25% of cardiac arrest victims gasp for air in the first few minutes. This can fool the 9-1-1 callers and attendants into thinking that the victim is still alive. The investigators have looked at all the studies on how to help 9-1-1 attendants to recognize abnormal breathing over the phone. The investigators have also learned what should be taught after finishing a large survey with 9-1-1 attendants from across Canada. This survey was done with the help of psychologists and other education experts. It measured the impact of attitudes, social pressures, and 9-1-1 attendants' perceived control over their ability to recognize abnormal breathing and cardiac arrest. Then the investigators developed a teaching tool which helped Ottawa 9-1-1 attendants recognize abnormal breathing. When they could do that, they could also recognize more cardiac arrest. The main goal of this project is to use the tool developed in Ottawa in more centres to help 9-1-1 attendants save the lives of even more cardiac arrest victims across Canada.
The quality of cardiopulmonary resuscitation (CPR) has been identified as an important determinants for patient survival, yet many studies revealed poor CPR guidelines compliance in real-life practice for both health care providers and lay persons. Common shortcomings identified include an insufficient number of chest compression, too rapid lung inflations, and too much hands-off time. The poor quality of CPR is associated with lower survival rate. Besides, some other problems could be found during resuscitation, such as prolonged intubation time, delayed first shock delivery or unsteady drug delivery interval. These problems can't be blamed on the only person but the teamwork. Certain measurements could improve the performance of the resuscitation team, such as audio prompt or checklist. Methods proposed and improvised to improve the quality of CPR have included CPR assisted devices, automatic driven devices or audio prompt system. However, some of these methods are hardly incorporate with the original resuscitation process since it could be an extra workload. Therefore, the investigators try to provide an digitized checklist combined with visual and audio alarming system, which could not only minimize the workload of chart recording but also remind the team to perform essential procedures in time. Information gained from a video-recording evaluation system had been employed to improve the resuscitation skills. The improvement of resuscitation quality also could be found through video-recording after certain intervention. It can also avoid the interference of the resuscitation and find out other harmful factors to CPR quality.
