An observational study in Out-Of-Hospital Cardiac Arrest, sponsored by Prehospital Center, Region Zealand. Completed. Per ClinicalTrials.gov, last updated 2022-10-17.
Sponsored by Prehospital Center, Region Zealand · Observational
The goal of this observational study is to investigate characteristics in out-of-hospital cardiac arrests (OHCA) related to sex differences.
The main questions it aims to answer are:
This analysis will be based on data from the national electronic based Danish OHCA registry. Data on OHCAs with resuscitative attempts in Denmark have been collected in the electronic based Danish Medical Service report system since 2016. The registry covers detailed data including the EMS report, executive entries, and advanced text searches of prehospital charts. All cases go through an elaborate validation process where all identified events are read through manually by an external verification team. This ensures high quality of data, collected according to the Utstein recommendations, throughout the approximately 5400 cases of OHCA in Denmark annually. During this verification process, supplementary sources of data are linked to each OHCA, among others information about survival, localization, initiation of bystander CPR and EMS personnel operation.
966 studies on the registry are indexed under Heart Arrest; 227 are open to participants now.
This study's enrollment of 27,000 is above the median of 200 across 383 observational studies indexed under Heart Arrest.
