Background: The aim of the European Registry of Cardiac Arrest (EuReCa) network is to provide high quality evidence on epidemiology of out-ofhospital cardiac arrest (OHCA) in Europe by supporting and developing cardiac arrest registries and performing European-wide studies. To date, the EuReCa ONE and EuReCa TWO studies have involved around 28 countries, with population covered increasing from the first to the second study. The aim of the EuReCa THREE study is to build on previous work and to support the promotion of quality data collection on OHCA throughout Europe. Methods/design: EuReCa THREE will be the third prospective cohort study on epidemiology of OHCA and will involve around 30 European countries. The study will be conducted between 1st September and 30th November 2022. Data will be collected on cardiac arrest cases attended, resuscitation attempted, patient and cardiac arrest event characteristics and outcomes (including return of spontaneous circulation, status on hospital arrival and discharge). A particular focus for EuReCa THREE will be to describe key time intervals in OHCA management; time from call to EMS arrival on scene, time from cardiac arrest to start CPR, time from EMS arrival to delivery of patient to hospital. EuReCa THREE was registered with the German Registry of Clinical Trials Registration Number: DRKS00028591 searchable via WHO metaregistry (https://apps.who.int/trialsearch/). Discussion: The EuReCa THREE study will increase our knowledge on longitudinal OHCA epidemiology and provide new knowledge on crucial time intervals in OHCA management in Europe. However, the primary aim of building a network to support quality data on OHCA, remains the central tenant of the EuReCa project.

The Out-of-Hospital Cardiac Arrest Outcomes (OHCAO) project aims to understand the epidemiology and outcomes of out-of-hospital cardiac arrest (OHCA) across the UK. This data linkage study is a subproject of OHCAO. The aim was to establish the feasibility of linking OHCAO data to National Health Service (NHS) patient demographic data and Office for National Statistics (ONS) date of death data held on the NHS Personal Demographics Service (PDS) database to improve OHCAO demographic data quality and enable analysis of 30-day survival from OHCA. Data were collected from 1 January 2014 to 31 December 2014 as part of a prospective, observational study of OHCA attended by 10 English NHS Ambulance Services. 28 729 OHCA cases had resuscitation attempted by Emergency Medical Services and were included in the study. Data linkage was carried out using a data linkage service provided by NHS Digital, a national provider of health-related data. To assess data linkage feasibility a random sample o...
Risk factors for out-of-hospital cardiac arrest: the Reykjavik Study
European Heart Journal, 2005
To examine risk factors for out-of-hospital cardiac arrest in the Reykjavik Study, a long-term, prospective, population-based cohort study that started in 1967. Methods and results From 1987 to 1996, 137 men and 44 women out of the 8006 men and 9435 women in the study sustained out-of-hospital cardiac arrest due to cardiac causes. Determinants included coronary artery disease (CAD), its classical risk factors, and age, body mass index (BMI), heart rate, cardiomegaly, and erythrocyte sedimentation rate. Electrocardiograms (ECGs) were examined for various abnormalities. Significance was determined by Cox regression analysis. In multivariable analysis, the risk in men was significantly associated with age, diastolic blood pressure, cholesterol, current smoking, and previous diagnosis of myocardial infarction (MI). In women, the risk was associated with diastolic blood pressure, elevated levels of cholesterol and triglycerides, and increased voltage on ECG. Increased BMI was inversely related to women's risk of out-of-hospital cardiac arrest. Conclusion In this prospective, population-based cohort study previous MI and the classical risk factors for CAD significantly increased the risk of out-of-hospital cardiac arrest, the endpoint of this study. Increased voltage on ECG additionally increased women's risk.
Epidemiology of pre-hospital outcomes of out-of- hospital cardiac arrest in Queensland, Australia
Objective: To describe incidence in pre-hospital outcomes of adult outof-hospital cardiac arrest (OHCA) of presumed cardiac aetiology, attended by Queensland Ambulance Service (QAS) paramedics between 2002 and 2014, by age, gender, geographical remoteness and socio-economic status. Methods: The QAS OHCA Registry was used to identify cases, which was then linked with Queensland Hospital Admitted Patient Data Collection and Queensland Death Registry. Population data were obtained for each calendar year by age and gender from the Australian Bureau of Statistics in order to calculate incidence rates. Four mutually exclusive pre-hospital outcomes were analysed: (i) no resuscitation (No-Resus); (ii) resuscitation, no pre-hospital return of spontaneous circulation (No-ROSC); (iii) resuscitation, pre-hospital return of spontaneous circulation not sustained to hospital (Unsustained-ROSC); and (iv) resuscitation, pre-hospital return of spontaneous circulation sustained to hospital (Sustained-ROSC). Results: Over the 13 years, there were 30 560 OHCA cases for analyses. Incidence was significantly greater in males than females and incrementally increased with age, for each outcome. Incidence of total OHCA events generally increased as remoteness increased cities: 72.39 per 100 000 [95% CI 71.35-73.45]; very remote: 87.01 per 100 000 [95% CI 78.03-95.98]). There was an inverse association between incidence of OHCA events and socio-economic status (SEIFA 1 and 2: 81.34 per 100 000 [95% CI 79.28-83.40]; SEIFA 9 and 10: 61.57 per 100 000 [95% CI 59.67-63.46]). Conclusion: Rural-specific strategies should be continued. Prevention and management strategies for OHCA targeting lower socio-economic groups require focus.
Hospital admissions and pharmacotherapy before out-of-hospital cardiac arrest according to age
Resuscitation, 2012
Background: The underlying etiology of sudden cardiac death varies with age and is likely to be reflected in type and number of healthcare contacts. We aimed to determine the specific type of healthcare contact shortly before out-of-hospital cardiac arrest (OHCA) across ages. Methods: OHCA patients were identified in the nationwide Danish Cardiac Arrest Register and Copenhagen Medical Emergency Care Unit (2001)(2002)(2003)(2004)(2005)(2006). We matched every OHCA patients with 10 controls on sex and age. Healthcare contacts were evaluated 30 days before event by individual-level-linkage of nationwide registers. Results: We identified 16,924 OHCA patients, median age 70.0 years (Q1-Q3: 59-80). OHCA patients had a higher number of hospitalizations and received more pharmacotherapy compared to the control population across all ages (p for difference <0.001). OHCA patients aged 70-79 and 80-89 years had the highest proportion of hospitalizations (70%) and pharmacotherapy (73%), respectively. In general, the association between OHCA and hospitalizations and pharmacotherapy was more pronounced among the youngest OHCA patients compared to controls. OHCA patients in age groups 14-19, 20-29, 30-39 were ∼5 times more likely to be in contact with the healthcare service than the control population (p for difference <0.001). Similarly, OHCA patients in the oldest age groups (60-69, 70-79, 80-89, >89) were <2 times more likely to be in contact with the healthcare services shortly before OHCA compared to the control population (p for difference <0.001). Conclusion: Young OHCA patients are more likely to be in contact with the healthcare services compared with an age and sex matched control population suggestive of traits that make them stand out from the general population.
Cardiac arrest management in general practice in Ireland: a 5-year cross-sectional study
2013
To document the involvement of general practitioners (GPs) in cardiac arrests with resuscitation attempts (CARAs) and to describe the outcomes. Design: A 5-year prospective cross-sectional study of GPs in Ireland equipped with automated external defibrillators (AEDs) and immediate care training by the MERIT Project, with data collection every 3 months over the 5-year period. Practices reported CARAs by quarterly survey with an 89% mean response rate (81-97% for the period). Setting: General practices throughout Ireland. Participants: 495 GP participated: 168 (33.9%) urban, 163 (32.9%) rural and 164 (33.1%) mixed. Interventions: All participating practices received a standard AED and basic life support kit. Training in immediate care was provided for at least one GP in the practice. Main outcome measures: Incidence of CARA in participating practices. Return of spontaneous circulation (ROSC) and discharge alive from hospital. Results: 36% of practices were involved in a CARA during the 5-year period and 13% were involved in more than one CARA. Of the 272 CARAs reported, ROSC occurred in 32% (87/272) and discharge from hospital in 18.7% (49/262). In 45% of cases, the first AED was brought by the GP and in 65%, the GP arrived before the ambulance service. More cases occurred in rural and mixed settings than urban ones, but the survival rates did not differ between areas. In 65% of cases, the GP was on duty at the time of the incident and 47% of cases occurred in the patient's home. Conclusions: These outcomes are comparable with more highly structured components of the emergency response system and indicate that GPs have an important role to play in the care of patients in their own communities. GPs experience cardiac arrest cases during the course of their daily work and provide prompt care which results in successful outcomes in urban, mixed and rural settings.

Introduction: The aim of the EuReCa ONE study was to determine the incidence, process, and outcome for out of hospital cardiac arrest (OHCA) throughout Europe. Methods: This was an international, prospective, multi-centre one-month study. Patients who suffered an OHCA during October 2014 who were attended and/or treated by an Emergency Medical Service (EMS) were eligible for inclusion in the study. Data were extracted from national, regional or local registries. Results: Data on 10,682 confirmed OHCAs from 248 regions in 27 countries, covering an estimated population of 174 million. In 7146 (66%) cases, CPR was started by a bystander or by the EMS. The incidence of CPR attempts ranged from 19.0 to 104.0 per 100,000 population per year. 1735 had ROSC on arrival at hospital (25.2%), Overall, 662/6414 (10.3%) in all cases with CPR attempted survived for at least 30 days or to hospital discharge. Conclusion: The results of EuReCa ONE highlight that OHCA is still a major public health pr...

Background: Despite the introduction of the concept known as "Chain of Survival" has significantly increased survival rates in patients with out-of-hospital cardiac arrest (OHCA), short-term mortality in this group of patients is still very high. Epidemiological data on OHCA in Poland are limited. The aim of this study was to create a prospective registry on OHCA covering a population of 2.7 million inhabitants of Upper Silesia in Poland. Presented herein is the study design and results of a three-month pilot study. Methods: The Silesian Registry of Out-of-Hospital Cardiac Arrest (SIL-OHCA) is a prospective, population-based registry of OHCA, of minimum duration which took 12 months; from January 1 st ,2018 to December 31 st ,2018. The first 3 months of the study constituted the pilot phase. The inclusion criterion is the occurrence of OHCA in the course of activity of the Voivodeship Rescue Service in the city of Katowice, Poland. Results: During the 3-month pilot phase of the study there were 390 cases of OHCA in which cardiopulmonary resuscitation was undertaken. Estimated frequency of OHCA in the population analyzed was 57 per 100,000 population per year. Shockable rhythm was present in 25.8% of cases. Return of spontaneous circulation was achieved in 35.1% of the whole cohort. 28.7% of patients were admitted to the hospital, including 2.8% of patients, who were admitted during an ongoing cardiopulmonary resuscitation. Conclusions: Prehospital survival of patients with OHCA in Poland is still unsatisfactory. It is believed that data collected in SIL-OHCA registry will allow identification factors, which require improvement in order to reduce short-and long-term mortality of patients with OHCA.
Incidence of Out-of-Hospital cardiac arrest
The American Journal of Cardiology, 2004
Estimates of the incidence of out-of-hospital primary cardiac arrest (CA) have typically relied solely upon emergency medical service or death certificate records and have not investigated incidence in clinical subgroups. Overall and temporal patterns of CA incidence were investigated in clinically defined groups using systematic methods to ascertain CA. Estimates of incidence were derived from a population-based case-control study in a large health plan from 1986 to 1994. Subjects were enrollees aged 50 to 79 years who had had CA (n ؍ 1,275). A stratified random sample of enrollees who had not had CA was used to estimate the population at risk with various clinical characteristics (n ؍ 2,323). Poisson's regression was used to estimate incidence overall and for 3-year time periods (1986 to 1988, 1989 to 1991, and 1992 to 1994). The overall CA incidence was 1.89/1,000 subject-years and varied up to 30-fold across clinical subgroups. For example, incidence was 5.98/1,000 subject-years in subjects with any clinically recognized heart disease compared with 0.82/1,000 subject-years in subjects without heart disease. In subgroups with heart disease, incidence was 13.69/1,000 subject-years in subjects with prior myocardial infarction and 21.87/1,000 subject-years in subjects with heart failure. Risk decreased by 20% from the initial to the final time period, with a greater decrease observed in those with (25%) compared with those without (12%) clinical heart disease. Thus, CA incidence varied considerably across clinical groups. The results provide insights regarding absolute and population-attributable risk in clinically defined subgroups, information that may aid strategies aimed at reducing mortality from CA. ᮊ2004
