Insights
Cardiovascular disease (CVD) is a leading cause of death in Europe, with significant regional variations in cardiac arrest incidence. Improving out-of-hospital cardiac arrest survival requires accurate, region-specific epidemiological data and robust registries like EuReCa.
Area of Science:
- Cardiology
- Public Health
- Epidemiology
Background:
- Cardiovascular disease (CVD) remains the primary cause of adult mortality in Europe, with cardiac arrest and sudden death from coronary ischemia being key contributors.
- While CVD incidence is declining globally due to improved prevention and treatment, in-hospital mortality rates decrease faster than out-of-hospital rates.
- Effective management of out-of-hospital cardiac arrest necessitates reliable epidemiological data and process metrics for quality improvement.
Purpose of the Study:
- To highlight the critical need for precise epidemiological data on cardiac arrest across diverse European regions.
- To emphasize the importance of standardized definitions and data collection for benchmarking and quality management of cardiac arrest response.
- To introduce the European Registry of Cardiac Arrest (EuReCa) as a tool for pan-European data integration and analysis.
Main Methods:
- Analysis of existing European data on cardiovascular disease and cardiac arrest incidence, noting significant regional disparities.
- Discussion of the Utstein and WHO definitions of cardiac arrest and sudden death, and their respective applications.
- Proposal for integrating data from multiple sources, including registries, surveys, death certificates, and medical records, to create a comprehensive understanding.
Main Results:
- Europe exhibits a 10-fold variation in coronary heart disease incidence and a 5-fold variation in emergency medical services-treated cardiac arrest rates across its regions.
- Current epidemiological data for cardiac arrest is insufficient and often lacks standardized definitions, hindering effective comparison and management.
- The European Registry of Cardiac Arrest (EuReCa) is proposed as a solution for standardized, pan-European data collection.
Conclusions:
- Accurate, region-specific epidemiological data is essential for improving out-of-hospital cardiac arrest survival rates.
- Standardized definitions and data collection methods are crucial for benchmarking and quality improvement across European regions.
- A holistic picture of cardiac arrest requires integrating data from diverse sources, facilitated by initiatives like EuReCa.
Abstract:
Major European institutions report cardiovascular disease (CVD) as the first cause of death in adults, with cardiac arrest and sudden death due to coronary ischaemia as the primary single cause. Global incidence of CVD is decreasing in most European countries, due to prevention, lifestyle and treatment. Mortality of acute coronary events inside the hospital decreases more rapidly than outside the hospital. To improve the mortality of cardiac arrest outside the hospital, reliable epidemiological and process figures are essential: "we can only manage what we can measure". Europe is a patchwork of 47 countries (total population of 830 million), with a 10-fold difference in incidence of coronary heart disease between North and South, East and West, and a 5-fold difference in number of EMS-treated cardiac arrest (range 17-53/1000,000/year). Epidemiology of cardiac arrest should not be calculated as a European average, but it is appropriate to describe the incidence of cardiac arrest, the resuscitation process, and the outcome in each of the European regions, for benchmarking and quality management. Epidemiological reports of cardiac arrest should specify definitions, nominator (number of cases) and denominator (study population). Recently some regional registries in North America, Japan and Europe fulfilled these conditions. The European Registry of Cardiac Arrest (EuReCa) has the potential to achieve these objectives on a pan-European scale. For operational applications, the Utstein definition of "Cardiac arrest" is used which includes the potential of survival. For application in community health, the WHO definition of "sudden death" is frequently used, describing the mode of death. There is considerable overlap between both definitions. But this explains that no single method can provide all information. Integrating data from multiple sources (local, national, multinational registries and surveys, death certificates, post-mortem reports, community statistics, medical records) may create a holistic picture of cardiac arrest in the community.
