Cardiac arrest & resuscitation
Accuracy of etiological classification of out-of-hospital cardiac arrest: A scoping review
Authors' conclusion
Major disparities exist between current etiological classifications based on the Utstein reporting template and robust sources such as autopsy and medical records.
Study context
- Population
- Studies reporting initial and confirmed etiologies of OHCA (Medline, EBM-Cochrane, Embase, 1946–2023)12 studies
- Comparison
- Emergency medical service (EMS)-based Utstein etiological classification vs confirmed etiology
- Outcome
- Agreement of EMS-based Utstein etiological classification of OHCA with other sources
