Cardiac arrest & resuscitation

Resuscitation of out-of-hospital cardiac arrest in China: A systematic review and Utstein-style data analysis based on the Chain of Survival

ResuscitationPublished Systematic review and meta-analysis of Utstein-style cohorts

Authors' conclusion

A low probability of first aid at multiple points is linked to poor survival following OHCA.

Study context

Pooled result

As reported in the abstract

Survival to discharge, by scenario
  • Resuscitation attempted by a bystander vs Resuscitation attempted by emergency medical service (EMS): P = 0.025
  • Resuscitation attempted by a bystander vs In-hospital treatment: P = 0.301
  • Values listed in the order of the four prespecified scenarios
