Relationship of Public Interest in Cardiopulmonary Resuscitation with Cardiac Arrest Epidemiology and National Socioeconomic Indicators: Exploratory Infodemiology Study.

For the sample of European countries, public interest in CPR or CA showed no relationship with real bystander CPR rates and therefore could not be recommended as a proxy of community readiness to attempt resuscitation. The association of RSV for CPR with the rate of ROSC and countries' socioeconomic characteristics suggests it could be used for identifying geographies with poor performance of prehospital systems in terms of managing CA, in particular where effective epidemiological surveillance for CA may be unavailable.
