Summary

This study will evaluated the epidemiology and the outcome of patients suffering out-of-hospital cardiac arrest in 27 european nations. The special focus in the EuReCa TWO study is on bystander CPR.

Detailed description

The importance of the establishment of out-of-hospital cardiac arrest (OHCA) registries as a critical step in improving OHCA outcomes is recognised from clinical, academic and political perspectives 1-4. The aim of the EuReCa project is to establish a European Registry of Cardiac Arrest to provide quality benchmarking for OHCA measurement in Europe based on Utstein style data collection, so that variations in OHCA incidence, management and outcomes can be identified 5,6. The EuReCa ONE project secured the collaboration of 27 European countries. During October 2014, data was collected from each of these countries, resulting in the most comprehensive estimate of OHCA incidence and outcomes to date 7. As expected, the proportion of variation between data collection from individual countries was considerable. While much of this variation is likely to be attributable to patient and system level differences, some variation was a consequence of the difference in proportions of countries covered by data collection, and may also have been caused by differences in how key variables were interpreted. Improving data quality is an incremental process therefore in EuReCa TWO, we aim to build on the work of EuReCa ONE and further improve understanding of OHCA incidence, management and outcome across the continent. Key to the overall aim of achieving quality benchmarking is to ensure that EuReCa data collection is comprehensive and reliable. Essential to the aims of the EuReCa project is that the data collected on each link of the Chain of Survival is comparable across participating countries. During EuReCa ONE, it was noted that the term 'bystander CPR' was interpreted differently across countries. A subsequent European survey of interpretation of the term 'bystander' and 'bystander CPR' confirmed this observation. In order to enhance the key quality requirements of comprehensiveness and reliability, the aims of the EuReCa TWO project will be as follows: * Expand the EuReCa network * Improve the understanding of the role of bystanders in OHCA in Europe In order to achieve these aims, the following objectives will be fulfilled: * Encourage participating countries to aim for national data collection and encourage additional countries to participate * In order to provide more robust estimates of incidence, management and outcome, increase the data collection period, increase the period of data collection to three months (1st October to 31st December 2017) * Identify consistency and variation in the use of the term 'bystander CPR' * Describe the incidence of 'bystander CPR' and its influence on OHCA outcome EuReCa TWO is expected to result in the creation of the largest ever database of OHCA European data, which has been collected over a single time period, using consistent data definitions. This will provide the opportunity to generate more robust estimates of OHCA incidence and outcome for particular subgroups. 2\. Research Questions In order to build on previous work and improve the robustness of estimates, the Research Questions in EuReCa TWO will closely mirror those of EuReCa ONE: * What proportion of each country's national population is covered by data collection? * What is the incidence of confirmed OHCA attended by the EMS in different European regions? * What is the incidence of any CPR (cardiopulmonary resuscitation) attempted in OHCA throughout Europe? * What proportion of CPR is started by: * Bystander - on scene by chance * Person alerted to scene by ambulance dispatch * EMS? * What is the age and gender profile of those who provide CPR before EMS arrival? * In OHCA, what is the initial cardiac arrest rhythm of the patients where bystanders or EMS starts CPR or any other resuscitation intervention - shockable or non-shockable? * In patients where CPR was started by bystanders or EMS, what is the incidence and rate of any return of spontaneous circulation (ROSC) after out-of-hospital cardiac arrest? * What is the incidence of patients never transported due to being declared dead on scene? * What is the patient status at handover from EMS to emergency department or hospital system with ongoing additional treatment in the next step of care (ROSC, ongoing CPR, dead)? * What is the incidence of patients who are still alive 30 days (whether in-hospital or discharged) after their cardiac arrest event and/or what is the incidence of patients who are discharged alive from hospital? * In patients with a witnessed collapse (witnessed by bystanders and/or EMS), found in a shockable rhythm and with an event of medical aetiology (i.e. Utstein comparator group): * What is the incidence of ROSC at hospital admission (at time of being handed over from EMS to emergency department or hospital system with ongoing additional treatment e.g. PCI) for the Utstein group * What is the incidence of patients who are still alive at 30 days (whether in-hospital or discharged) after their cardiac arrest event and/or what is the incidence of patients who are discharged alive from hospital in the Utstein group? * What factors determine ROSC, admission and survival (as defined in questions above)? Secondary Research Questions * What is the European incidence of and percentage survival from OHCA with a traumatic aetiology? * What is the European incidence of and percentage survival from OHCA in cases brought to hospital with unsustained ROSC and/or ongoing CPR?
