Influence of nationwide policy on citizens' awareness and willingness to perform bystander cardiopulmonary resuscitation

Aims: Public awareness to cardiopulmonary resuscitation (CPR) and cardiac arrest is influenced by systemic factors including related policies and legislations in the community. Here, we describe and compare the results of the two nationwide CPR surveys in 2007 and 2011 examining public awareness and attitudes to bystander CPR in South Korea along with changes in nationwide CPR policies and systemic factors. Methods: This population-based study used specially designed questionnaires via telephone surveys. We conducted bi-temporal surveys by stratified cluster sampling to assess the impact of age, gender, and geographic regions in 2007 (n = 1029) and in 2011 (n = 1000). Logistic regression analysis was performed to identify factors associated with willingness to perform bystander CPR. Results: Public awareness of automated external defibrillators increased from 3.0% in 2007 to 32.6% in 2011. The proportion of the population that underwent CPR training within the previous 2 years increased significantly from 26.9% to 49.0%. The factors most related with intention of bystander CPR were male gender, younger age, CPR awareness, recent CPR training, and qualified CPR learning. In 2011, 75.8% of respondents were more willing to perform bystander CPR for stranger vs. 68.3% in 2007 (p = 0.002). Additional dispatcher hands-only CPR increased this proportion (85.8%, p < 0.001). However, bystander CPR experience rates remained unchanged (3.6-3.9%). Conclusion: Changes in nationwide CPR policies and systemic factors affected citizens' awareness and willingness to perform bystander CPR. Additionally, applied dispatcher hands-only CPR and publicity increased public willingness to perform bystander CPR. (C) 2013 Elsevier Ireland Ltd. All rights reserved.
