An observational study of Cardiac Arrest, run by AfterROSC at 27 sites in 2 countries.
Trial summary
Even in patients with successful return of spontaneous circulation (ROSC), outcome after cardiac arrest remains poor. The overall in-hospital survival rate widely varies both worldwide and across communities, from 1 to 4 folds according to circumstances of arrest and post-resuscitation interventions.

About this study
Even in patients with successful return of spontaneous circulation (ROSC), outcome after cardiac arrest remains poor. The overall in-hospital survival rate widely varies both worldwide and across communities, from 1 to 4 folds according to circumstances of arrest and post-resuscitation interventions. Several studies have already shown that early interventions performed after ROSC, such as treatment of the cause, targeted temperature management, optimal hemodynamic management and extra-corporeal life support in selected patients, could improve the outcome in post-cardiac arrest patients. However, the decision process regarding the allocation of these resources, in parallel with the management of patients' proxies, remains a complex challenge for physicians facing these situations. Consequently, several prediction models and scores have been developed in order to stratify the risk of unfavorable outcome and to discriminate the best candidates for post-resuscitation interventions. Overall, several scores exist, but external validation are lacking and direct comparisons are needed to assess relative interest of scoring systems. Indeed, establishing the optimal scoring system is crucial, for optimal treatment allocation and appropriate information to relatives.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Even in patients with successful return of spontaneous circulation (ROSC), outcome after cardiac arrest remains poor. The overall in-hospital survival rate widely varies both worldwide and across communities, from 1 to 4 folds according to circumstances of arrest and post-resuscitation interventions. Several studies have already shown that early interventions performed after ROSC, such as treatment of the cause, targeted temperature management, optimal hemodynamic management and extra-corporeal life support in selected patients, could improve the outcome in post-cardiac arrest patients. However, the decision process regarding the allocation of these resources, in parallel with the management of patients' proxies, remains a complex challenge for physicians facing these situations. Consequently, several prediction models and scores have been developed in order to stratify the risk of unfavorable outcome and to discriminate the best candidates for post-resuscitation interventions.

Where is the study taking place?
The record lists 27 sites in France, Belgium. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Determination of Area Under Curve of Cerebral Admission Hospital Prognosis (CAHP) Score at intensive care unit admission (time frame: Intensive Care Unit Admission (Usually 3 hours after cardiac arrest)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04167891, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Sep 2024.
