The impact of dispatcher-assisted CPR and prior bystander CPR training on neurologic outcomes in out-of-hospital cardiac arrest: a multicenter study

ResuscitationPublished Prospective observational cohort study

Authors' conclusion

DA-CPR and prior CPR training play crucial roles in improving favorable neurological outcomes in bystander-witnessed OHCA cases. Additionally, DA-CPR may be particularly effective for untrained bystanders.

Study context

Population
Patients with non-traumatic out-of-hospital cardiac arrest (OHCA) witnessed by laypersons, 42 emergency hospitals in the SOS-KANTO 2017 study (September 2019-March 2021)analysed
