A multifaceted intervention to increase bystander CPR rates after out-of-hospital cardiac arrest in France: a stepped-wedge, cluster-randomised, controlled trial.
This stepped-wedge, cluster-randomised controlled trial assessed a coordinated intervention to increase bystander CPR before EMS arrival among adults with non-traumatic out-of-hospital cardiac arrest in France.
Why it matters
Bystander CPR is an important early response to OHCA, and this trial suggests that combining dispatcher support, volunteer activation, and agency feedback can increase its use.
