Authors' conclusion

Barriers to DA-CPR after dispatcher recognition of cardiac arrest were common and associated with delayed bystander CPR and worse outcomes. Targeting these barriers could improve dispatcher call handling and bystander CPR rates.

Study context

Population
Transcribed emergency calls for out-of-hospital cardiac arrest in which the dispatcher recognised cardiac arrest, from five OHCA studiesconfirmed OHCA
Participants
3,263 participants
Exposure
Barrier-present vs barrier-free calls

Main finding

As reported in the abstract

At least one barrier

Confirmed OHCA with at least one barrier

43.7%

Observational data: associations, not effects.
