A multifaceted intervention to increase bystander CPR rates after out-of-hospital cardiac arrest in France: a stepped-wedge, cluster-randomised, controlled trial.
The Lancet. Public health·November 1, 2026·PMID 42901186
Why it mattersBystander CPR is a critical determinant of survival after out-of-hospital cardiac arrest, yet rates remain suboptimal. This trial provides real-world evidence that a coordinated, system-level intervention can significantly increase bystander CPR rates, offering a scalable model for EMS systems to strengthen the early links in the chain of survival.
