INTRODUCTION: Out-of-hospital cardiac arrest is a global health care problem. Like other cities in the world, Hong Kong faces the impact of such events. This study is the first territory-wide investigation of the epidemiology and outcomes of out-of-hospital cardiac arrest in Hong Kong. It is hoped that the findings can improve survival of patients with cardiac arrest. METHODS: This study was a retrospective analysis of the prospectively collected data on out-of-hospital cardiac arrest managed by the emergency medical service from 1 August 2012 to 31 July 2013...

BACKGROUND: Use of automated external defibrillators (AEDs) has been recommended for pediatric out-of-hospital cardiac arrest (OHCA). However, there are no conclusive studies that elucidated the effectiveness of public-access defibrillation (PAD) in children. METHODS: This was a nationwide, population-based, propensity score-matched study of pediatric OHCA in Japan from 2011 to 2012, based on data from the All-Japan Utstein Registry. We included pediatric OHCA patients (aged 1-17 years) who received bystander cardiopulmonary resuscitation...

INTRODUCTION: This study reports the epidemiology and outcomes from out-of-hospital cardiac arrest (OHCA) in England during 2014. METHODS: Prospective observational study from the national OHCA registry. The incidence, demographic and outcomes of patients who were treated for an OHCA between 1st January 2014 and 31st December 2014 in 10 English ambulance service (EMS) regions, serving a population of almost 54 million, are reported in accordance with Utstein recommendations...

OBJECTIVE: Out-of-hospital cardiac arrests (OHCA) in high-rise buildings experience lower survival and longer delays until paramedic arrival. Use of publicly accessible automated external defibrillators (AED) can improve survival, but "vertical" placement has not been studied. We aim to determine whether elevator-based or lobby-based AED placement results in shorter vertical distance travelled ("response distance") to OHCAs in a high-rise building. METHODS: We developed a model of a single-elevator, n-floor high-rise building...

INTRODUCTION: The survival rate of out-of-hospital cardiac arrest in Hong Kong is low. A long delay between collapse and defibrillation is a contributing factor. Public access to defibrillation may shorten this delay. It is unknown, however, whether Hong Kong's public is willing or able to use an automatic external defibrillator. This study aimed to evaluate public knowledge of how to use an automatic external defibrillator in out-of-hospital cardiac arrest. METHODS: A face-to-face semi-structured questionnaire survey of the public was conducted in six locations with a high pedestrian flow in Hong Kong...

Background Early defibrillation plays a key role in improving survival in patients with out-of-hospital cardiac arrests due to ventricular fibrillation (ventricular-fibrillation cardiac arrests), and the use of publicly accessible automated external defibrillators (AEDs) can help to reduce the time to defibrillation for such patients. However, the effect of dissemination of public-access AEDs for ventricular-fibrillation cardiac arrest at the population level has not been extensively investigated. Methods From a nationwide, prospective, population-based registry of patients with out-of-hospital cardiac arrest in Japan, we identified patients from 2005 through 2013 with bystander-witnessed ventricular-fibrillation arrests of presumed cardiac origin in whom resuscitation was attempted...

Out-of-hospital cardiac arrest (OHCA) is considered an important health issue worldwide, and early defibrillation is a key element for a favourable prognosis. In South Korea, public access defibrillation (PAD) programmes were initiated in 2007. However, the impact of PAD programmes on OHCA survival rates remains unclear. This study evaluated the deployment and maintenance status of public automatic external defibrillators (AED), including how frequently they were used, in Busan Metropolitan City, South Korea...

OBJECTIVE: To evaluate the time-independent effect of the early administration of epinephrine (EPI) on favorable neurological outcome (as CPC [cerebral performance category] 1-2) at 1 month in patients with out-of-hospital cardiac arrest. MATERIALS AND METHODS: A total of 119 639 witnessed cardiac arrest patients from 2008 to 2012 were eligible for this nationwide, prospective, population-based observational study. Patients were divided into EPI group (n = 20 420) and non-EPI group (n = 99 219)...

BACKGROUND: Immediate access to an automated external defibrillator (AED) increases the chance of survival for out-of-hospital cardiac arrest (OHCA). Current deployment usually considers spatial AED access, assuming AEDs are available 24 h a day. OBJECTIVES: The goal of this study was to develop an optimization model for AED deployment, accounting for spatial and temporal accessibility, to evaluate if OHCA coverage would improve compared with deployment based on spatial accessibility alone...

BACKGROUND: Actual application of public-access automated external defibrillator (AED) pads to patients with an out-of-hospital cardiac arrest (OHCA) by the public has been poorly investigated. METHODS: AED applications, prehospital characteristics, and one-month outcomes of OHCAs occurring in Osaka Prefecture from 2011 to 2012 were obtained from the Utstein Osaka Project registry. Patients with a non-traumatic OHCA occurring before emergency medical service attendance were enrolled...

AIM: Early defibrillation should achieve the highest survival rates when applied within the first minutes after the collapse. Public access defibrillation programs have increased the population awareness of the importance of defibrillation. Schoolchildren should be trained in basic life support (BLS) skills and some countries have included BLS in their school syllabus. However, little is known of the current knowledge and ability of schoolchildren to use an automated external defibrillator (AED)...

BACKGROUND: The occurrence of out-of-hospital cardiac arrest (OHCA) is a critical life-threatening event which frequently warrants early defibrillation with an automated external defibrillator (AED). The optimization of allocating a limited number of AEDs in various types of communities is challenging. We aimed to propose a two-stage modeling framework including spatial accessibility evaluation and priority ranking to identify the highest gaps between demand and supply for allocating AEDs...

BACKGROUND: Characteristics and outcomes of emergency patients with bath-related sudden cardiac arrest in prehospital settings have not been sufficiently investigated. METHODS AND RESULTS: From a prospective population-based registry, which covers all out-of-hospital cardiac arrests (OHCAs) in Osaka City, a total of 642 patients who had a bath-related OHCA from 2012 to 2014 were enrolled in the analyses. The characteristics and outcomes of OHCA were compared by three locations of arrest: home baths (n=512), public baths (n=102), and baths in other public institutions (n=28)...

Sudden cardiac death (SCD) in a young seemingly healthy athlete is a tragic and often highly publicized event. Preparticipation screening aims to identify those affected by cardiovascular diseases who may be at higher risk of SCD during sports participation. There are conflicting recommendations from the American Heart Association and the European Society of Cardiology regarding screening electrocardiograms (ECGs) before participation in sports. The use of an ECG as a screening strategy has been questioned, with a large number of abnormal test results observed in athletes resulting from the electrocardiographic changes that occur in a highly trained individual overlapping with findings suggestive of a pathologic condition...

BACKGROUND: Speed is the cornerstone of rescue for out-of-hospital cardiac arrest. As a consequence, community participation programs have been initiated to decrease response times. Even in the very best of these programs, however, short-term survival rates hover around 10% and long-term survival rates are half that. In most locales, survival is far worse. In Piacenza, Italy, responders have been trained for more than a decade to use publicly available automated external defibrillators (AEDs) and eschew the performance of cardiopulmonary resuscitation (CPR)...
