Abstract 13201: Increase in Bystander Cardiopulmonary Resuscitation in Sweden During the Last 15 Years is Mainly Attributed to Increased Rates of “Chest Compression Only” CPR
Introduction: Bystander cardiopulmonary resuscitation (CPR) traditionally consists of both ventilations and chest compressions. The concept of Compression Only CPR (CO-CPR) has emerged since rescue breaths are difficult to perform, potentially delay the start of CPR, and interrupt chest compressions. Since 2010 guidelines suggest CO-CPR for untrained bystanders and for trained bystanders unwilling or unable to perform rescue breaths.
Aim: The aim was to describe changes in rates of bystander CPR, CO-CPR and survival during 3 different time-periods of CPR-guidelines on a national level. We hypothesized that dissemination of CO-CPR would be associated with increased CPR-rates and similar survival compared to standard CPR.
Method: A registry based cohort study including all bystander witnessed cases of out-of-hospital cardiac arrests reported to the Swedish Cardiac Arrest Registry in 2000 - 2014. Exposure was categorized as bystander CPR or No-CPR. Bystander CPR was further categorized into Standard CPR (S-CPR) or CO-CPR. Primary outcome was 30-day survival.
Results: 23169 patients were included. Total rates of bystander CPR increased from 38% in 2000-2005 to 70% in 2011-2014. CO-CPR increased from 5% in 2000-2005 to 28% in 2011-2014. There was no significant difference in survival among patients receiving CO-CPR or S-CPR (13,6% vs. 12,9% p=0,3).
Conclusion: The increase in bystander CPR during the last 15 years in Sweden is mainly attributed to an increase in CO-CPR. Any form of bystander CPR was associated with increased 30-day survival compared to no CPR in all time periods studied. Overall 30-day survival was not different when comparing CO-CPR to S-CPR.
